There he devoted himself to composing his famous Biblical commentary.

It produced the leading scholars European Jewry, including Yaakov ben Yakar, the teacher of Rashi. Around the year 1000, Rabbenu Gershom called assembly of rabbis to deal with complex, pressing issues of the day, during which he instituted various laws and bans. These include the prohibition against polygamy, the requirement of a wife to consent to divorce, the requirement to accept any Jew who had been forced to convert to Christianity and wishes to return, and the ban against opening and reading another person's mail. Asher ben Yechiel (Rosh) said about these laws that they became "such permanent fixtures that they are treated as if handed down on Mount Sinai." The title "Ma'or Hagolah" (Light of the Exile) was reverently appended to his name.
Son of the "Beit Yaakov" of Izhbitz and author of numerous works, he is known primarily for his efforts in identifying the Chilazon fish from which Techeilet is manufactured, and strongly encouraged the renewal of it's usage in the mitzvah of Tzitzit.

With royal support he was able to save the Jewish communities of Aragon and Roussillon during the anti-Jewish riots of 1391, as well as send thousands of Conversos to Northern Africa and Eretz Yisrael. He was perhaps the first European philosopher to argue against Aristotelian philosophy.

Shalom Sharabi. He mastered Talmud, kabbalah and Jewish history at an early age. Though born and raised in Jerusalem, he spent much of his life as an emissary from the Land of Israel traveling throughout the Jewish communities of Europe and raising funds for the support of communities in the Land of Israel. His scholarship, knowledge of multiple languages, physical resilience and bravery made him an ideal candidate for the task of emissary, upon the success of whose mission the survival of the Jewish community of Chevron rested. Wherever he went, he visited famous libraries and examined books and manuscripts and later described in Shem Gedolim, his unique and indispensable biographical dictionary. He read widely, seemingly remembered everything, and wrote and published numerous works on almost every imaginable Torah topic.

Avraham ben Meir ibn Ezra, better known simply as Ibn Ezra, was a medieval Spanish Torah commentator, poet, philosopher and grammarian. While he wrote on grammar, philosophy, astronomy, medicine, and mathematics, he is most famous for his Biblical commentaries, which, alongside those of Rashi, are ubiquitous and indispensable. His commentaries focus on grammatical explanations and the "peshat" (plain-sense) meaning of the text. He often incorporates biting or humorous comments directed toward other commentators, especially towards the Karaites. He maintained a deep friendship with R. Yehudah Halevi, and quotes some of his interpretations in his commentaries. His poetry is still read and sung as part of the regular liturgy. Ibn Ezra knew great poverty and traveled widely, almost incessantly, teaching and making connections with fellow scholars, notably Rabbenu Tam in France.
A prolific Italian rabbi, kabbalist and merchant, he spent several years in Palestine studying from the great kabbalist rabbis there. Among his writings was the Mishnat Hasidim, a reformulation of Kabbalistic concepts according to the organization of the Mishnah.

Isaac Luria (also known as Ari HaKadosh or Arizal), was a rabbi and mystic who taught in Egypt and Safed in the sixteenth century. He is considered the forefather of modern Kabbala, also known as Lurianic Kabbala. Born in Jerusalem, but educated in Egypt under the auspices of the David bin Abi Zimra (Radbaz) and Bezalel Ashkenazi, Luria became one of the Radbaz's leading student. He lived a life of seclusion on an island in the Nile but was eventually forced to turn to commerce. It was during this period of seclusion that he developed his famous system of kabbalistic ideas. After moving to Safed, Luria taught his system to many followers, who copied down and interpreted his ideas. Shrouded in secrecy, many legends developed about his life, which were only furthered after his death at a young age. Luria’s students mostly memorized his teachings and put them in writing. Among the transmitters of Luria’s kabbalistic ideas were Eleazer Azikri, Israel Sarug, Elijah de Vidas, Abraham Galante, Moses Jonah, Menahem Azariah Fano, Joseph ibn Ṭabul and Joseph Solomon Delmedigo. None of them, however, was as instrumental in disseminating Luria’s teachings as his closest disciple, Ḥayyim Viṭal. The Lurianic version of Kabbala, far as it was from Luria’s original teaching, became the mainstream form of Kabbala. Its popularity in the Jewish world, even in circles that had never before practiced Kabbala, contributed to the upsurge of messianism that set the ground for the Sabbatean movement and Shabbetay Ṣevi.
Isaac Samuel Reggio, also known as the YaShaR, was a linguist, scholar and religious philosopher who applied the principles of enlightenment philosophy to the understanding of Torah.

Yitzchak ben Moshe Arama was a Spanish rosh yeshiva, Talmudic commentator, preacher and philosophically-oriented exegete. He served as rosh yeshiva in Zamora and, subsequently, as chief rabbi of Tarragona. The poor inhabitants of that city could not support a beit midrash, but implored him to give public lessons and sermons. His sermonic style, fusing didactic philosophical as well as ethical teachings, served as a model for generations of darshanim, or preachers. These sermons formed the basis of his masterpiece, Akedat Yitzchak. Later, he served as chief rabbi in other cities. When Jews were expelled from Spain in 1492, he moved with his son, Meir, to Portugal, and then from there to southern Italy. He greatly admired the Rambam, but felt that the philosophical commentators who succeed him took the Rambam's philosophical approach in directions he never intended. His teachings are brought so consistently, and often anonymously, by Abarbanel in his commentaries that Meir Arama accused him of plagiarizing his father's works.
One of the foremost Tosafists, frequently quoted throughout the pages of the Tosafot commentaries on the Talmud. On his father's side he was a grandson of R' Simchah ben Samuel of Vitry, author of the Machzor Vitry; on his mother's side he was a great-grandson of Rashi and a nephew of Rabbeinu Tam, Rashbam, and Rivam. He was surnamed "haZaḳen" (the elder) to distinguish him from his disciple, Isaac ben Abraham "haBachur" (the younger), also a Tosafist.
14th century Spanish Halakhic authority. Born in Barcelona (according to other accounts: Valencia), he was a prime disciple of Rabbeinu Nissim (Ran), and was imprisoned in Barcelona on false charges together with his teacher and several others. After they were acquitted, he left Barcelona and accepted a Rabbinic position in Saragossa. However the city was beset by strife, which prompted him to leave and settle in Valencia where he directed a Talmudic academy. The persecution of the Spanish Jews in 1391 forced him to flee to Algeria, where he was received with much honor.
Isaac de Leon, (born in Toledo - not to be confused with Isaac Leon ibn Tzur, author of Megilat Esther on Rambam), a Kabbalist and author of Maʿaseh Nissim, was a native of Leon, and the pupil of Isaac Campanton. He was part of the Kabbalistic circles that produce the work "Sefer Ha-Meshiv". An opponent of philosophy, he nonetheless studied Aristotelian logic as part of the formal approach to halakhah of the school of Isaac Campanton. Joseph Karo and others honored him with the title of "the great teacher." He was more than seventy years of age at his death, which occurred shortly before the expulsion of the Jews from Spain.
Yitzchak Sagi Nahor (Isaac the Blind) was a Provencal rabbi and kabbalist. He was the son of the Ra'avad, and was active at the time that Sefer HaBahir was first emerging in public; in some circles he was considered its author.

In 1621 he moved to the Land of Israel, where he was appointed chief rabbi of the Ashkenazic community in Jerusalem. He moved to Tzfat and Teveriah shortly after being ransomed from captivity in 1625, where he further immersed himself in kabbalist study. His great work, Shnei Luchot HaBrit, published by his son, is almost unparalleled in its impact on Ashkenazic Jewish life, playing an enormous role in spreading and popularizing kabbalistic ideas. He had a huge impact upon the Chassidic movement, which sprang up soon after his passing, through his teachings and his descendants, some of whom were great Chassidic leaders.
Prominent Italian Tosafist and prolific author, (sometimes referred to as "Rid HaZaken" or "Rid HaRishon", to differentiate him from his grandson who was a famous scholar as well).

He also wrote "Shevilei de'Rakiya", an introduction to the principles of Rabbinical astronomy, and "Drush Ohr HaChayim", a treatise discussing the eternity of the soul and the age of the universe, in addition to other lengthy essays, many of which are appended to his Mishnah commentary. His ethical will contains twenty-eight paragraphs, consisting primarily of moral and ascetic precepts.
Israel Meir (HaKohen) Kagan, also known as the Chofetz Chaim, was one of the foremost leaders of Ashkenazic Jewry. He was a posek, rosh yeshiva and writer on Jewish ethics whose seminal works, Chafetz Chaim and Shmirat HaLashon, have come to define the rules of proper speech.

Senior disciple of the founder of Chassidut, the Baal Shem Tov, Jacob Joseph was one of the chief disseminators of his master's teachings through his published works. Born into a prominent rabbinical family, he was serving as rabbi in Sharograd, Western Ukraine, and was initially opposed to the fledgling Chasidic movement, but changed course after an inspirational meeting with the Baal Shem Tov. His embrace of Chasidism caused him to forfeit his position in Sharograd, whereupon he took up rabbinic posts in Rashkov (1748-1752), and then Nemirov (1752-1770), before finally settling in Polonne (1770-1782). His works, the titles of which all contain allusions to the author's name, are: "Toldot Yaakov Yosef", which was the first book of Chassidic teachings ever published; "Ben Porat Yosef"; "Tzofnat Paneach"; and "Ketonet Pasim".

He also composed a Torah commentary which remained in manuscript for centuries, a small extract of which, known as Ba'al HaTurim al HaTorah, was based primarily on gematria-based associations. These were lead-ins to the main body of his work, eventually published in full, which draws on the works of other commentators, particularly that of Ramban.
Yedidiah Solomon ben Abraham Nortsi was an Italian rabbi, Biblical scholar and grammarian. He served as rabbi of Mantua for some thirty years.

Italian rabbi and scholar in the early 16th century. He was also an author, publisher, and writer of responsa. Widely known is his commentary on the festival prayer book according to the Roman rite, published anonymously under the title 'Kimcha D'Avishuna' (Bologna, 1540). He was extremely active as a proofreader of midrashic works and in the establishment of accurate readings of the tractates he studied with his pupils.

Of his three sons the best known is Raphael Joseph who was a posek, as well as a book publisher.
Yonatan Eybeschutz was a German rabbi, Talmudist, posek, kabbalist and homilist, writing prolifically in all of these fields. He was a child prodigy and his personality created a great impression upon people from early on. He spent many years as a rosh yeshiva and dayyan in Prague, but he was never appointed as chief rabbi of a city due to suspicions that he was secretly a Sabbatean. While he stridently denied the allegations, the suspicions continued, espoused especially by Rabbi Yaakov Emden, who deciphered cryptic names in amulets prepared by Rabbi Yonatan as being Sabbatean in nature, and believed to have found connections between his writings and those of an acquaintance. A contemporary rabbinical tribunal exonerated him of the allegations, and his works are widely studied to this day. In 1750, he was elected rabbi of the "Three Communities:" Altona, Hamburg, and Wandsbek. He was a preacher of great force and eloquence, and his collected homilies are amongst the most widely read today.
14-15th century Spanish rabbi and philosopher, disciple of R' Hasdai Crescas and author of "Sefer HaIkkarim" on Jewish philosophy and faith.

Joseph Ber Soloveitchik was a major 20th Century American Orthodox rabbi, Talmudist, and modern Jewish philosopher. He was a scion of the Lithuanian Jewish Soloveitchik rabbinic dynasty. As a Rosh Yeshiva of Rabbi Isaac Elchanan Theological Seminary at Yeshiva University in New York City, The Rav, as he came to be known, ordained close to 2,000 rabbis over the course of almost half a century. He served as an advisor, guide, mentor, and role-model for tens of thousands of Jews, both as a Talmudic scholar and as a religious leader. He is regarded as a seminal figure by Modern Orthodox Judaism. During his tenure at Yeshiva University, in addition to his Talmudic lectures, Soloveitchik deepened the system of "synthesis" whereby the best of religious Torah scholarship would be combined with the best secular scholarship in Western civilization. In his major non-Talmudic publications, which altered the landscape of Jewish philosophy and Jewish theology, Soloveitchik stresses the normative and intellectual centrality of the halakhic corpus. In The Lonely Man of Faith, Halakhic Man, and Halakhic Mind is a four-part analysis of the historical correlation between science and philosophy. Only in its fourth and last part does the author introduce the consequences on the Halakha of the analysis performed in the previous three parts.
Yosef Dov Soloveitchik, also known as the Beis HaLevi, was a rabbi and scholar and the first of the Soloveitchik dynasty. His mother, Rivke, was the granddaughter of Rabbi Chaim of Volozhin. R. Yosef Dov quickly became known for his great genius and kindness of heart. In 1854, he was invited to be co-Rosh Yeshiva of the Volozhin Yeshiva together with R. Naftali Zvi Yehudah Berlin. In 1865, he became Rabbi of Slutsk, where, upon discovering the impoverishment of the heder children, he instituted community sponsored lunches. Two of his pupils in Slutsk were R. Yosef Rosen – later known as the Rogatchover Gaon – and R. Zalman Sender Shapiro. In 1875, struggles with the Maskilim ultimately forced him to leave Slutsk. In 1878 he was offered the rabbinate of Brisk, a position he held until his death in 1892. Over his lifetime he produced numerous published works, including Talmud commentaries, halachic insights, responsa and sermons, which were all printed under the title "Beit HaLevi."
Joseph ibn Megas (Hebrew: יוסף בן מאיר הלוי אבן מיגאש) was a Rabbi, Posek, and Rosh Yeshiva in Lucena, also known as Ri Migash. He studied under the renowned Talmudist Isaac Alfasi (Rif) before being appointed Rosh yeshivah (President of the Academy) after the latter’s death. His most famous pupil was Maimon, the father of Rambam. Although Rambam in his writings seems to indicate that he was himself a pupil, this is unlikely being that he was all of six when Ibn Migash died, rather his intention must have been that he absorbed Ibn Migash's teachings from his father. Ibn Megash authored over 200 responsa in Judeo-Arabic (later translated into Hebrew), and a Talmudic commentary of which only the novellae on tractates Bava Batra and Shevuot are currently extant.
16th century Bible commentator, a member of the famous Ibn Yachia family which produced many great Torah scholars. He composed a commentary on the Five Megilot, and a book on Gan Eden and the afterlife called "Torah Ohr." Two other books, "Derech Ha-Chaim" and "Ner Mitzva" were lost during the burning of the Talmud in Padua in 1414. His son Gedaliah is the author of "Shalsheles HaKabbalah".
Yosef Karo, expelled from Spain as a child, was a rabbi, Talmudist, mystic and the pre-emiment halachic codifier. His best-known work, the Shulchan Aruch, was accepted in his lifetime and formally recognized thereafter as the definitive statement of Jewish legal and religious practice. He also wrote basic commentaries on the Mishneh Torah and the Arba'ah Turim (the latter forming the basis from which the Shulchan Aruch was distilled). He was also a mystic who received heavenly revelations. Some of these were set down in writing and formed the impetus to come to the Land of Israel. There, he lived in Tsfat, where he took a central role in the attempt by his teacher, Rabbi Yaakov Berav, to revive traditional rabbinic Semichah.
12th century Bible commentator and grammarian. He was born in Spain, but religious persecution by the Mujahideen forced him to flee with his family to Provence, where he settled in Narbonne. He wrote a commentary on the Torah and several books on Hebrew grammar.

His sons, R' Moshe and R' David (Radak), were also famous Biblical commentators.
One of the greatest and most original Jewish minds of the last few generations, he was connected to Chabad Chassidut throughout his life. Nevertheless, he also studied under Rabbi Chaim Soloveitchik in Slutzk. Hence he was universally accepted and answered a large quantity of responsa well beyond his responsibilities as the rabbi of the chassidic community of Dvinsk. His most famous work was his Tzafnat Paneach commentary on Rambam's Mishneh Torah.
Yosef ben Meir Teomim was a Polish/German posek and Talmud scholar. In 1744 he left Lemberg (Lvov) for Komarno, where he married and served as the town melamed, devoting many hours to learning and composing his various works. In 1767, he moved to Berlin in order to devote himself undisturbed to his studies and his writing, and it was there that he published some of his works. Upon the death of his father, the townspeople of Lemberg implored him to take the former's place. After several years, he finally agreed, and in 1774 he returned to serve as dayan, darshan (preacher) and rabbi of Lemberg. In 1781 he was appointed rabbi and av beit din in Frankfurt. Though he published several works on different Torah subjects, his fame derives from Pri Megadim, a comprehensive super-commentary on Shulchan Aruch and its early commentaries.

Toward the end of his life, he was captured and held by German Christian authorities. His disciples raised the huge ransom demanded, but he refused to allow its payment, aware of the precedent it could set. He died in prison and was ransomed years later for Jewish burial. His most prominent disciple, Asher ben Yechiel (the Rosh), fled to Spain in the wake of what befell his teacher.
Shmuel Eidels (Maharsha) was a Polish rabbi and Talmudist whose chiddushim (Talmudic novellae) on both halachic and aggadic passages are found in almost every edition of the Talmud. He was a child prodigy and initially rejected many marriage offers to devote himself entirely to Torah study. After marrying, he moved to Posen and established a yeshiva which was supported for twenty years by his mother-in-law, Eidel. He adopted her name as his surname in gratitude for her unstinting support. He was an active participant in the Council of Four Lands.
Shlomo Luria (Maharshal) was a Polish rabbi, posek and Talmudic commentator. His prominent family claimed descent from Rashi. He served as rosh yeshiva of the famed yeshiva in Lublin, Poland.

His great halachic work, Yam shel Shlomo, was overshadowed by the contemporary Shulchan Aruch, of whose halachic methodology he was highly critical.
Meïr Leibush ben Yehiel Michel Weisser (Malbim) was a rabbi, Hebrew grammarian, halachic scholar, and author of one of the most insightful and comprehensive Torah commentaries since medieval times. Known as the "ilui (prodigy) of Volhynia," he served in seven different rabbinic posts over the course of his lifetime. His staunch adherence to halacha and defense of tradition put him in direct confrontation with "enlightened" intellectuals who wished to introduce Reformist innovations in worship and other communal institutions. While serving as chief rabbi of Bucharest, he was falsely charged by his opponents and he only escaped imprisonment on the condition that he leave Romania. Persecution by reformers followed him to other rabbinic posts, including Lunchitz, where he was additionally attacked by a Chassidic faction that accused him of introducing enlightenment thought in his Torah commentary. On his way to accept a post in Krementchug, he fell sick in Kiev and died on the first day of Rosh HaShanah.
Markus Horovitz was a Hungarian rabbi and historian.

Horovitz was rabbi in Frankfurt at a time when the disagreements between the Orthodox and Reform factions were reaching their peak. Horovitz was appointed to chair a committee on ritual to placate the Orthodox followers of Samson Raphael Hirsch, who were threatening to found a separate community, the Israelitische Religionsgesellschaft ("Religious Society of Israelites"). He was given authority over the entire community's religious institutions, and promoted the construction of a new Orthodox synagogue on the Börneplatz, which was dedicated on September 10, 1882. Horovitz promoted the coexistence between the different factions, maintaining that it was possible for a unified community to exist while both sides exercised autonomy over their own institutions.
Marcus Jastrow was a Talmudic scholar and author of the widely used Talmudic dictionary which bears his name in popular parlance. He was rabbi of the Orthodox congregation Rodeph Shalom in Philadelphia from 1866 to 1892.

He studied under the great Turkish rabbis of Izmir, R' Chaim Abulafia and R' Yitzchak HaKohen Rappaport, after which he emigrated to Jerusalem together with the latter. He was subsequently sent as an emissary to North Africa in order to raise funds for the Jerusalem community. The Libyan Jewish community at that time was at a spiritual low point and they requested that he remain there and become their leader. He accepted and was appointed chief rabbi of Tripoli, a position he held for 20 years until his death in 1768. In addition to his work on Rambam, he wrote novellae on the Talmud and Five Megilot, as well as drashot (sermons), but these have never been published.

He was appointed to the Toledo Beth Din and head of an important yeshiva in Toledo. He was so highly esteemed that on his father's death in 1225 the latter's honorary title of Nasi (prince) was applied to him. A fierce opponent of philosophy, he first entered the controversy over the Guide for the Perplexed of Maimonides. However, over the years his opposition waned, and when the subject was reopened some thirty years later he refrained from getting involved. He was a prolific author and wrote a number of Talmud novellae, but only commentary on two tractates are extant, entitled "Yad Ramah". He also wrote halakhic responsa, a commentary on the mystical book Sefer Yezirah and a book on the laws of writing a Torah scroll.

He had an encyclopedic knowledge of philosophical and kabbalistic literature, and his commentaries on Rambam's Mishneh Torah and on Chumash are noted for their originality and depth. His knowledge of the Jerusalem Talmud was so thorough that he was able to immediately determine that two supposedly "newly discovered" tractates were forgeries. He was very beloved by his congregation, and though he received offers of rabbinic posts in Jerusalem, New York, Kovno and other cities, he retained his position in Dvinsk for almost 40 years.

Menachem Mendel of Lubavitch was third rebbe of the Chabad-Lubavitch Hasidic movement. His mother died shortly after his birth and he was raised by his grandfather, Rabbi Shneur Zalman, the Alter Rebbe of Chabad. After the death of his uncle, Rabbi Dov Baer, the Mittler Rebbe, he tried unsuccessfully to persuade the Chassidim to accept other candidates as rebbe, and only acceded to their demands after three years. He was a recognized Posek (decisor of Jewish law) and his many responsa were published in the influential work by which he is known, "Tzemach Tzedek". He also wrote a mystical exposition of the mitzvot, "Derech Mitzvotecha". In opposing the Haskalah, he formed a strong bond with prominent leaders of the Mitnagdim (opponents of Chassidism), which lead to a kind of rapprochement. He actively promoted the expansion of Chabad yeshivot in towns in which there were concentrations of Chabad Chassidim, and he sent students to lift the spirits of young cantonist (boys taken into the Russian army with the intent of their eventual apostasy). He was succeeded as rebbe by his youngest son, Shmuel, while other sons set up competing Chabad courts, some of which persisted until World War 2.
Menachem Mendel Schneerson, known as "The Rebbe," was the last Chabad-Lubavitcher rebbe and the pioneer of the Jewish outreach movement. Under his leadership, Chabad emerged from relative obscurity to become one of the most influential forces of Jewish life in the 20th century. Escaping Nazi Europe, he arrived in New York in 1941, where he became the head of Chabad's educational and social service networks. In 1951 he succeeded his father in law as Rebbe and immediately expanded the "shlichut" system that had been established by his predecessor, sending pairs of yeshiva students to far-flung Jewish communities to reconnect Jews to their heritage. He also worked actively internationally, helping to free thousands of Iranian Jews during the 1979 revolution, and later providing for the religious and educational needs of Jews trapped inside the Soviet Union. He authored a commentary on the Passover Haggada and a special calendar for Chabad Chassidim, but the bulk of his scholarship was not recorded directly by him, but was rather culled from his numerous talks delivered on special occasions, from personal notes discovered after his death, and from his vast correspondence. This material fills tens of volumes and still has not been completely published.

In 1777, he headed the emigration of 300 of his followers to the Holy Land. He first settled in Safed, but facing persecution from the Turks, he relocated to Tiberias, where he is buried. The works containing his teachings are: "Pri Ha'Aretz", Pri Ha'eitz" and "Likutei Amarim".

10th century Hebrew grammarian and poet, author of "Machberet", an early dictionary of the Hebrew language. He served as assistant to the statesman Hasdai ibn Shaprut of Cordoba, at whose request he compiled the dictionary. However, not everyone agreed with his linguistics. Chief among his opponents was the philologist Dunash ben Labrat, who wrote an extensive criticism of Menahem's work. However, Machberet did not lose it's authoritativeness, and is quoted frequently some 200 years later by such luminaries as Rashi and Rabbeinu Tam.
13th century German scholar, author of a Halachic compendium bearing the same name. Mordechai was a primary student of Maharam M'Rotenberg and a son-in-law of R' Yechiel of Paris. His work, known simply as "The Mordechai", is a compilation of Halakhic rulings and customs enacted by the great sages of that and preceding generations. It follows the order of Rif's "Sefer Halachot", and is printed immediately after the Rif in the Vilna Shas. Being that the author collected the material but did not actually publish it in final form, there are two vastly different versions of this work — the Rhenish edition and the Austrian edition. Our editions of Talmud contain the Rhenish version, which is the shorter of the two. Mordechai was martyred together with his entire family in 1298 during the "Rhindfleish" massacres in Nuremberg.
Mordechai Yosef Leiner of Izbica was a Hasidic thinker and founder of the Izhbitza-Radzyn dynasty.

He was born in Crakow to Yisrael, (also known as "Isserl", from which was fashioned the surname "Isserles"), and studied under Shalom Shachna of Lublin, who later became his father-in-law. He became Rabbi in Crakow and established a yeshiva there, which he funded from his own resources. He also served on the Council of the Four Lands. His other works are: Torat Chatat on kosher dietary laws; Torat HaOlah, a philosophical explanation of the Holy Temple and it's sacrifices; Teshuvot Rama (responsa); and Mechir Yayin, an allegorical commentary on the Book of Esther, which was written in his youth one Purim under difficult circumstances and given to his family in lieu of mishloach manot.
Rabbi Moshe Rivkes was born in Prague and settled, early in life, in Vilna, Lithuania. His father, R' Naphtali Hirsch Sofer of Vilna, was a scribe and a great Torah scholar. His mother, Rivkah, took upon herself the financial support of the family so her husband could devote himself to his studies, as a result of which the surname "Rivkes" was appended to her son's name, in deference to her. In 1655, when Cossack hordes descended upon Vilna and committed widespread massacres, Rabbi Moshe was forced to flee the city along with R' Shabtai Hacohen (the author of the Shach), R' Ephraim HaCohen (the author of Sha’ar Ephraim), and R' Aaron Shmuel Kaidanover (the author of Birkat HaZevach). They eventually found refuge in Amsterdam, where R' Moshe published his great work on the Shulchan Aruch, entitled "Be’er HaGolah". It indicates the various sources for the Halachic decisions of the Mechaber and Rama, along with brief comments by the author. Although he was accorded great respect in Amsterdam, Rabbi Moshe yearned to return to Vilna, his hometown, and he succeeded in doing so before his death. The Vilna Gaon was a descendant of R' Moshe and often cites him in his "Biur HaGra" on Shulchan Aruch.
Moses Sofer (Schreiber), better known by the name of his work "Hatam Sofer", was one of the leading Orthodox rabbis of Austrian - Hungarian Jewry in the first half of the nineteenth century. He was a teacher to thousands and a powerful opponent to the Reform movement in Judaism, which was attracting many people from the Jewish communities in the Austrian Empire and beyond. He was born in Frankfurt to R' Shmuel Sofer, and studied under Rabbi Nathan Adler and Rabbi Pinchas Horowitz (Hafla'ah). After marriage he became head of the yeshiva in Prostějov, following which he accepted a rabbinical position in Strážnice, and subsequently in Mattersdorf. In 1807 he was appointed as Rabbi of Pressburg (Bratislava), where he also founded a large Yeshiva that produced many students who themselves became noted rabbis. As Rabbi of the city of Pressburg, he maintained a strong Orthodox Jewish perspective through communal life, first-class education, and uncompromising opposition to Reform and radical change. Sofer published very little during his lifetime, but his posthumously published works include more than a thousand responsa, novellae on the Talmud, sermons, biblical and liturgical commentaries, and religious poetry. He is an oft-quoted authority in Orthodox Jewish scholarship and many of his responsa are required reading for semikha (rabbinic ordination) candidates. He had 10 children with his second wife, who was the daughter of R' Akiva Eiger, two of whom were renowned rabbis in their own right. The eldest, Avraham Shmuel Binyamin (Ketav Sofer), inherited his father's position as rabbi of Pressburg. His second son, Shimon (Michtav Sofer), was the rabbi of Krakow.
Moshe ben Yitzchak Yehudah Lima was a Polish/Lithuanian rabbi and posek. He learned in Cracow and served as rabbi in Slonim before moving to Vilna and, at the end of his life, to Brisk.

In Spain he was instrumental in convincing many who had intermarried to repent and give up their non-Jewish wives. In 1240, he was was one of the four rabbis who were required to defend the Talmud against the accusations of the apostate Nicholas Donin in a public disputation in Paris, which led to the public burning of the Talmud. He also authored Tosafot on the Talmud, of which his commentary on Yoma is printed in the Vilna Shas as "Tosafot Yeshanim".
Author of the Chassidic classic "Degel Machaneh Ephraim." He was a son of the Baal Shem Tov's daughter Udel, and brother of R' Baruch of Medzhybizh. (His sister Faiga was the mother of R' Nachman of Breslov.) After his grandfather's death, he studied under the Maggid of Mezeritch and R' Jacob Joseph of Polonne. In 1780, he settled in Sudilkov (near Shepetivka) where he served as Maggid until 1785. He then returned to Medzhybizh and served as Rebbe there until his death in 1800. He is buried next to his grandfather, the Baal Shem Tov, in Medzhybizh.
Moshe Chaim Luzzatto (Ramchal) was an Italian rabbi, kabbalist and philosopher who also wrote dramatic works and literary criticism. Gifted with an almost photographic memory, he wrote many works, some which became standards of kabbalah and ethics. He was suspected of Sabbateanism, but was exonerated by his teachers and colleagues with a warning to cease engaging in speculative kabbalistic writing. Toward the end of his life he moved to the Land of Israel.
Moshe Cordovero, also referred to as RaMaK, was a leading kabbalist who lived and taught in Tsfat. His best-known work, Pardes Rimmonim, is a systematization of various school of kabbalistic thought. He authored many highly influential works, included a defense of kabbalah, a highly-regarded ethical work based on kabbalistic thought, and a comprehensive commentary on the Zohar. He had many disciples and was considered the premier kabbalistic authority until superseded by R. Yitzchak Luria shortly after his death.
Rabbi of the Community Synagogue of Monsey, New York, and senior Rosh Yeshiva at Yeshiva University's RIETS and Professor of Jewish Medical Ethics and Biology at Yeshiva College. He is a son-in-law of R' Moshe Feinstein, and himself a noted expert on Jewish medical ethics and their relationship to Halakha.
Leading decisor of Jewish law of the 20th century and Rosh Yeshiva of Mesivta Tiferet Jerusalem in New York. Born in Uzda, Belarus, and served as rabbi in Luban for 16 years. After suffering from oppression under the Soviet regime, he moved with his family to New York City in 1937 where he lived for the remainder of his life. He authored the multivolume responsa "Igrot Moshe", as well as novellae on Talmud entitled "Dibrot Moshe".
A student of Rabbi Yaakov Beirab, he was part of the kabbalistic circles of Safed. He was appointed that community's rabbi at the age of twenty and continued in that role for the next fifty-five years. During that time, he authored many works including two volumes of responsa and an important commentary on Rambam's Mishneh Torah.
Moshe de Leon was a Spanish rabbi and kabbalist. Though he wrote kabbalistic works which appeared under his name, his most famous association is with the Zohar, which is attributed to the Tanna, Rabbi Shimon bar Yochai. Due to his intimate involvement in the emergence of the Zohar, some attribute its composition, in part or in its entirety, to him. This association figured in controversies surrounding the Zohar shortly after it became widely known. He was widely knowledgeable both in philosophy and Kabbalah, and he was a gifted writer with a flair for evocative turns of phrase. He dedicated two of his works to Todros HaLevi Abulafia. He spent most of his adult years in Guadalajara, before moving to Avila in his latter years.
Nachman of Breslov was one of the most creative chassidic masters, whose thought and teachings continue to resonate within wide circles far beyond his immediate followers. He was a great-grandson of the founder of Chassidut, R. Yisrael Ba'al Shem Tov, and a grandson of another early chassidic master, R. Nachman of Horodenka. Among his many works are a profound presentation of his chassidic and mystical teaching, Likkutei Moharan, and a compilation of his intricate and powerfully evocative stories, Sippurei Ma'asiyot. Another work relates the events of his transformative journey to and from the Land of Israel. He was severely criticized by certain contemporary chassidic masters, but defended by the leading chassidic master, R. Levi Yitzchak of Berdichev. He moved to Uman less than a year before he passed away from tuberculosis, and his grave there is a pilgrimage site for thousands to this day.
A product of Enlightenment-era Germany, Wessely came from a wealthy family with business connections to many of the leaders of Europe. He studied Torah under Rabbi Yochanan Eybeschutz, but received a broad education as well. Later, he worked with Moses Mendelssohn on the Biur translation of the Torah into German, and also wrote many other works. He became controversial for his vigorous support for the study of German and secular studies in Jewish schools.
Naftali Zvi Yehudah Berlin (Netziv) was a Lithuanian rabbi and one of the greatest scholars of his time. He was born into a family of Jewish scholars, a descendant on his mother's side of Meir Eisenstadt. His first wife was the granddaughter of R. Chaim Volozhin, and his second the daughter of R. Yechiel Michel Epstein. In 1854 he was appointed head of the Volozhin yeshiva, where he introduced a style of Talmud study based on broad knowledge of Tannaitic and Geonic literature as well as the Rishonim. He also emphasized the importance of the study of Chumash and Nach, giving a daily shiur on the weekly parsha. In 1894 he was forced to close the yeshiva by the Russian government, which demanded that secular studies replace Talmud study until 3:00 pm each day. He was the father of R. Chaim Berlin and R. Meir Bar-Ilan (Berlin).
Natan ben Yechiel of Rome was an Italian rabbi and lexicographer. His central work, the Aruch, was the first Talmudic dictionary and achieved a wide circulation soon after publication. He worked as a peddler of linen, until the opportunity came to devote himself entirely to Torah study. He travelled abroad to study with luminaries in Sicily and Narbonne, eventually returning to serve as head of the yeshiva in Rome.
Main disciple of R' Nachman of Breslov and leader of the movement after his death. However, he did not actually assume his teacher's position as Rebbe of Breslov, being that R' Nachman had not named a successor. R' Nathan is the one responsible for preserving R' Nachman's teachings by recording, publishing and disseminating them. He also authored many of his own works, including the multi-volume "Likutei Halachot", an esoteric work which follows the order of the Shulchan Arukh.
Nathaniel Weil was a German rabbi and Talmudist born to Rabbi Naphtali Zvi Hirsch Weil. A child protégé he was quickly permitted to attend the lectures of R. Abraham Broda for advanced students. He was appointed Rabbi in Metz but after almost a decade returned to Prague where he taught Talmud and was the assistant rabbi. After being expelled from Prague, he was appointed to the rabbinate of Mühringen where he started his commentary on the Rosh before moving to Karlsruhe and completing it. His remaining writings were published posthumously.
Nissim ben Jacob (Nissim Gaon) was a rabbi, Talmudic commentator and leader of the Jewish community of Kairwan, Tunisia. He learned primarily from his father, Rav Yaakov Gaon – a student of Hai Gaon – and Chushiel ben Elchanan. After his father's death, he was chosen by the Babylonian academies of Sura and Pumbedita as his replacement as head of the academy of Kairwan. He maintained an active correspondence with Hai Gaon and with Shmuel Hanaggid, creating a channel of discourse between eastern and western schools of Jewish thought. His most famous student was Isaac Alfasi (Rif).
Onkelos, according to tradition, was a Roman convert to Judaism who lived in the first or second century. He translated Tanach into Aramaic, the spoken language of the day. Some identify Onkelos with a convert named Aquilas who translated the Tanach into Greek. According to tradition, he was counseled by his uncle, the emperor, to succeed by buying low and selling high. He later explained his conversion to his incensed uncle by repeating to him his own advice from years past. Onkelos' translation became the standard Aramaic translation, used daily by Jews world-wide long after Aramaic ceased being a living language for most Jews.
Ovadiah MiBartenura was an Italian rabbi, banker, Mishnaic commentator and community leader. He studied under Maharik Kolon in Bolonya. In 1485 he began a 2.5 year journey to the Land of Israel, evidently upon the death of his wife. He visited in many communities along the way, eventually settling in Jerusalem. He quickly became prominent, and labored unceasingly to restore Jewish communal life, both material and spiritual, there to the prominence it had lacked for so long. He was largely successful in his efforts; he reestablished a hevra kadisha in which he actively served, as well as a yeshiva upon the arrivals of learned Spanish exiles. He was recognized as a halachic authority, served as chief rabbi of Jerusalem (recognized as such also by the Moslem authorities), succeeded in reducing the tax burden upon the community, and revived the use of Hebrew by delivering his weekly Shabbat sermons in the holy tongue. His commentary on Mishnah is to the Mishnah what Rashi's is to the Talmud – basic, straightforward, and indispensable to this day.
Ovadiah Yosef was the Sephardi Chief Rabbi of Israel from 1973 to 1983 and the greatest halachic authority for Sephardic Jewry in the modern era. He was born in Baghdad and made aliyah to Jerusalem with his family at the age of four. In 1950 he was appointed dayan to the rabbinical court of Petach Tikva, where he issued the first of many bold and innovative rulings that marked his career. In 1984 he became a notable figure in Israeli politics by founding the ultra-Orthodox Sephardi party Shas, serving as its spiritual leader until his death in 2013.
Late 13th century Tosafist, author of "Tosafot Rabbeinu Peretz" on the Talmud, of which only a few tractates are currently extant. He also authored glosses on "Sefer Mitzvot Katan" written by his teacher R' Isaac of Corbeil, and on "Sefer HaTashbetz" by his student R' Samson ben Tzadok. A Masoretic work entitled "Sefer Peretz" is no longer extant.
Pinchas ben Yosef Halevi was a brother of the famous Spanish Talmudist, R. Aharon Halevi. Little is known about the details of his life. Some recent scholars have argued that he was the author of the anonymous work often ascribed to his brother R' Aharon, Sefer HaChinukh.
Rabbi Aharon HaLevi (Ra'ah) was a Spanish rabbi, Talmudic commentator, posek and critic of Rashba's Torat HaBayit. He was born in Gerona, Spain to a long line of rabbis reaching back to the Baal HaMaor. He studied with his father, Rabbi Joseph HaLevi, as well as with Ramban. Although he was originally ascribed authorship of Sefer HaChinukh, this attribution has been undermined and, of late, refuted.
Avraham ben David of Posquieres (Ra'avad) was a Provencal rabbi, Talmudic commentator, and mystic. His best-known works are his extensive critical comments on Rambam's Mishneh Torah which are published alongside the Rambam's text in almost every version. He also engaged in written disputes via commentary with his younger contemporary, R. Zerachiyah Halevi, in defence of the Rif's Halachot. He wrote talmudic commentaries which are quoted extensively by a number of Rishonim, but have been lost for the most part. It was from his circle that Kabbalah emerged in the 12th century, and the early prominent kabbalists cite his activity as central to that emergence.
Eliezer ben Natan (Ra'avan) was a German rabbi, posek and commentator. His contemporaries and successors refer to him as an authoritative transmitter and decisor of Jewish tradition and practice. Among his descendants and relatives were some of the great rabbinic figures of the next generations. He was one of the first Ashkenazic scholars to quote extensively from the Talmudic commentary of Rabbeynu Chananel. He was also the first German scholar to pen commentaries on piyyut (liturgical poetry).
Eliezer ben Yoel Halevi (Ra'avyah) was a German rabbi, posek and Talmudic scholar. Wandering between communities in Germany and France, he refused to serve in a formal rabbinic position until poverty compelled him to accept a rabbinic position in Cologne, where he became famous. His halachic works were considered authoritative and indispensable to his and subsequent generations. His brother's martyrdom caused him to grieve so intensely that his vision was impaired, and he dictated his later works to students. He was also active as as one of the Ba'alei HaTosafot.
Yonah Gerondi (Rabbeinu Yonah) was a Spanish rabbi, Talmudist and ethicist. His best-known work is Sha'arei Teshuva, a comprehensive work on repentance. He also wrote chiddushim (Talmudic novellae) on a number of tractates, quoted by contemporaries and later authors. He was one of the most prominent opponents of the Rambam's philosophical works. When the attacks on the Rambam's works culminated in a public burning of wagon-loads of Talmud by Christian authorities, Rabbeinu Yonah publicly admitted his error in involving outside players, and gave Rambam a prominent and revered place in his teaching. It is surmised that this turn of events motivated Rabbeinu Yonah to write Sha'arei Teshuva.
Yaakov ben Meir (Rabbenu Tam) was a French rabbi, halachic authority, liturgical poet and one of the greatest of the Ba'alei HaTosafot. His renown extended from his native France and Germany to Spain and beyond. In his Tosafot commentary, he often disagrees with the opinion of his grandfather, Rashi. The best known of these disagreements is in regard to the order of the passages contained in the head-worn tefillin, and it continues to impact daily Jewish practice to this day. He narrowly escaped death at the hands of Crusaders. He befriended Ibn Ezra during the latter's stay in France, and they maintained a subsequent correspondence.
Yerucham ben Meshulam, better known as Rabbenu Yerucham, was a Spanish rabbi and halachist. He was a student of the Rosh. His two works of halacha, Sefer Meisharim and Sefer Toldot Adam v'Chavah, were published together and known popularly as "Rabbenu Yerucham". His rulings are quoted by R. Yosef Karo in his Beit Yosef. Popular legend has led to few editions of Rabbenu Yerucham's works being printed, as those who commented on or reproduced the work were reputed to have suffered.
Rabbi Eliyahu Ben Harush was a 19th century Moroccan rabbi. He was known for his great humility and constant devotion to Torah study. His sermons and poetry were also highly admired. He served briefly as the chief rabbi of Alkatzar, but did not find it to his liking and returned to his home of Sefrou after only a short time. He wrote a commentary on the Chumash and the Haggadah.
Chananel ben Chushiel (Rabbeinu Chananel) was a North African rabbi and talmudist. He is considered one of the first Rishonim and studied under the last of the Geonim. His family was from Italy and migrated to Kairowan, where he ultimately attained great renown. He served as rosh yeshiva in Kairowan after the passing of his father. He maintained a lively correspondence with the heads of the great yeshivot in Babylonia. He was also successful in business and attained great wealth. His is the earliest comprehensive commentary on the Talmud.
David Kimchi (Radak) was a Provencal rabbi, biblical commentator, grammarian and philosopher, born to a family of grammarians and commentators. His father, R. Yosef Kimchi, wrote a popular polemic work defending Judaism against Christian attacks and his brother, Moshe, was a well-known commentator. Radak himself participated in a number of public religious disputations to defend Judaism. He also took part in the disputes surrounding Rambam's philosophical works. Influenced by Ibn Ezra and the Rambam in philosophical matters, he sided the those who supported the permissibility of philosophic study. Radak cautioned, however, that it should be undertaken only by those whose faith was well-grounded. His commentaries on Tanach display his grammatical mastery, and are amongst the most basic and and commonly referenced.
Levi ben Gershon (Ralbag) was a Provencal philosopher, physician, mathematician, astronomer, Talmudic commentator and Torah commentator. He seems to never have accepted a rabbinic post, and little is known about his life – even the place and date of his death is unclear. Ralbag was a strict Aristotelian, and in his great philosophical work, Milchamot Hashem, he critiques Rambam on some points where he deviates from Aristotelian teaching. He was also a fervent believer in astrology, and astrological determinism pervades his philosophical work, though he did maintain the notion of human free-will. His philosophical views lead to opposition to his works in some circles. His mathematical works were sophisticated, influential and ground-breaking; he is noted for his work in combinatorics and early use of the principle of mathematical induction. Some of these works were even translated into Latin at the request of Christian scholars. The Ralbag was credited for inventing the 'Jacob's staff,' an astronomical device. Finally, he is perhaps best known today for his commentary on the Tanach, which displays his wide learning and interweaves halachic matters and rulings. He wrote several Talmudic works, most of which have since been lost.
Rabbi Moshe ben Maimon (Rambam) was perhaps the greatest intellectual and spiritual figure of post-Talmudic Judaism. He wrote indispensable works of philosophy, Halacha, commentary, and responsa. Born in Spain, his family fled while he was still a youth. After an extended period in Morocco, he settled in Egypt, where he became Nagid (leader) of the Jewish community. His works were all foundational in their field. He was the first to produce a comprehensive commentary on the entire Mishnah. His great work of philosophy, Moreh Nevuchim, spawned an entire discipline and had incalculable influence upon enthusiastic promoters and vehement opponents alike. His code of law, Mishneh Torah, is the first and unsurpassed comprehensive code of Jewish law and practice. He also served as court physician to the Muslim leader Saladin. All of his works were written in Judeo-Arabic except for Mishneh Torah, which was written in a magnificent Hebrew. The precision of his expression is legendary. His descendents served as Negidim of Egypt for another four generations.
Moshe ben Nachman, also known as Ramban, was a leading Torah scholar of the middle ages who authored commentaries on Torah and the Talmud. He was a posek who wrote responsa and stand-alone works on Halachic topics, as well as works on mysticism, science and philosophy. Ramban's commentary on the Torah often critiques earlier commentaries and incorporates kabbalistic teachings. He was born in Gerona, Spain, where he established a large yeshiva which produced hundreds of disciples who became leaders of Spanish Jewry. In 1263 he took part in a debate in Barcelona with an apostate Jew named Pablo Christiani, at the behest of the Church. In 1267, at the age of 72, he immigrated to the Holy Land, where he settled in Akko (Acre). He died there at age 76.
Rabbi Nissim ben Reuven (Ran) was a Spanish rabbi, Talmudic commentary and philosopher and the pre-eminent Spanish halachic authority of his generation. His commentaries to the Talmud and to Hilchot HaRif are main elements of yeshiva curriculum to this day. He was responsible for the establishment of the yeshiva and beit din in Barcelona. Like his predecessor, Rashba, Ran's renown extended to Jewish communities well beyond Spain, who addressed their questions to him and sought his guidance. He was not inclined toward Kabbalah, but tended toward a more philosophical bent in his great ethical work, Derashot HaRan.
Rabbi Raphael Aharon ben Shimon was born in Rabat 1848 and died in 1928 in Tel Aviv. At young age was appointed to serve as the secretary to his father’s court in Jerusalem. He travelled as an emissary to Germany and France on behalf of the yeshivah Doresh Zion in Jerusalem, but upon the death of his father, he was appointed emissary on behalf of the board of the Morocco Community in Jerusalem. He used this as an opportunity to gather and published the writing of Moroccan Jewry. Later he was appointed as Chief Rabbi (Hakham Bashi) in Egypt (1891-1921). His final years were spent in Tel Aviv as Judge.
Shlomo ben Avraham ibn Adret (Rashba) was a Spanish rabbi, Talmudic commentator, posek and community leader in the 14th century. He lived his entire life in Barcelona. He is considered the most outstanding student of the Ramban, and continued his approach in Talmudic exposition, authoring chiddushim (Talmudic novellae) on many tractates which remain mainstays of Torah study to this day. His yeshiva drew exceptional students from throughout the Jewish world, including quite a number from Germany. He functioned as chief rabbi of Spain and wrote over one thousand responsa to individuals and communities throughout the Jewish world. He was involved in opposition to Rambam's philosophical writings and prohibited the study of philosophy under the age of 25. He also defended Judaism to Christian and Moslem polemicists, and vigorously opposed the activity of R. Avraham Abulafia. He vigorously defended his work, Torat HaBayit, against R. Aharon Halevy's often strident comments.
Shmuel ben Meir (Rashbam) was a French Tosafist and Torah commentator. He was a son of Rashi's daughter, Yocheved, and older brother of the famous Tosafists, Isaac ben Meir (Rivam) and Jacob ben Meir (Rabbeinu Tam). His Torah commentary is concise, and hews strictly to the concept of the "peshat" or plain-sense meaning of the text, sometimes at the expense of received rabbinic traditions. He does not hesitate to argue with Rashi when he feels that his commentary strayed from the plain meaning of the verse. Rashbam also wrote a lengthier commentary on the Talmud, portions of which are printed in the Vilna Shas where no commentary of Rashi is available. Rashbam's opinions are also frequently mentioned in the Tosafot throughout Shas.
Shlomo ben Yitzhak, best known by the acronym "Rashi", was an early and influential medieval Torah and Talmud commentator. He was born in Troyes, France, and as a young man he studied in the yeshivot of Worms and Mainz. At the age of twenty-five he returned to Troyes and opened his own yeshiva. He supported his family and his yeshiva by growing grapes and producing and selling wine.Widely known as the father of all commentators, his commentary on the Bible and Talmud is considered an indispensable tool for Torah study. He described his aim as clarifying the "peshat" or "plain-sense" meaning of each verse. He was also a posek who authored responsa.
Menachem ben Binyamin Recanati was an Italian kabbalist and posek. Very little is known about his life. He was one of the first well-known kabbalists in Italy, though he also was strongly influenced by the prominent Chassidei Ashkenaz figures, R.Yehudah Hechasic and R. Eleazar Rokeach. His kabbalistic commentary to the Torah was translated into Latin and played an important role in the emergence of Christian kabbalah.
Yitzchak Alfasi, better known as the Rif, was a North African rabbi, Talmudic commentator, and posek. His most famous work is Hilchot HaRif, a digest of Talmudic discussions which omits the lengthy deliberations and focuses on the conclusions, followed by the Rif's decisions, which became widely authoritative and formed one of the pillars of the Shulchan Aruch. He is sometimes considered the last of the Geonim, due to the great authority and reverence he enjoyed. His teacher was Rabbenu Chananel, and among his students were R. Yehudah Halevi and R. Yosef (the Ri) Migash.
Rabbi Yom Tov ben Avraham Isbilli (Ritva) was a Spanish rabbi and Talmudic commentator. His commentaries to many tractates of the Talmud are a mainstay of yeshiva study to this day. Some see in the surname 'Isbili' an indication that he was born in Seville in southern Spain, but this is in doubt as his grandfather was also known by this surname. He was a leading student of Re'ah and Rashba. In addition to his Talmudic studies, he also devoted significant time and energy to the study of Rambam's Moreh Nevuchim and other philosophical works. He served as rabbi of Saragossa, where he established a beit din and yeshiva.
Yitzchak ben Asher Halevi (Riva) was one of the first Ba'alei HaTosafot. He lived in Speyer and was a student of Rashi. He also seems to have studied with Rashi's teacher, R. Yitzchak ben Yehudah, and, after Rashi's death, with Rashi's son-in-law, R. Meir ben Shmuel. His grandson, bearing the same name, died a martyr's death in Speyer in 1196 during a pogrom instigated by a blood libel. He was given great respect by the leading sages of his generation, and was renown for his piety and asceticism.
Yehudah ben Natan (Rivan) was a French rabbi, Talmudic commentator and one of the early Baa'lei HaTosafot. He was a son-in-law of Rashi and in certain ways extended his work. He is quoted in many places throughout the Tosafot.
Asher ben Yehiel was a prominent Talmudic commentator, posek and one of the Ba'alei Hatosafot. He was born, lived and taught in Germany, fleeing with his family to Spain after the imprisonment and death of his teacher, Maharam of Rothenburg. He served as as leading authority in Spain alongside the Rashba. Due to the tremendous impact of his work, Hilchot HaRosh, his halachic authority was so widely regarded that he was one of three sages selected by R. Yosef Karo to serve as the "Beit Din" for his Beit Yosef and Shulchan Aruch.
Sa'adia was a Polish/Lithuanian rabbi and prominent disciple of the Gra. He lived in his house, studied closely with him and served as a manuensis for a number of his works. He was sent by the Gra to publicize the latter's strident opposition to Chassidism. He came to the Land of Israel as one of the leaders of the second wave of the aliyah of the Gra's students.
Saadia Gaon (Rasag) was a philosopher, posek, biblical commentator, polemicist, grammarian and pre-eminent Jewish leader of Mesopotamian Jewry. He was born and educated in Cairo, Egypt. In 928 he was appointed Gaon (preeminent spiritual and temporal leader) of the academy of Sura, and subsequently his influence spread throughout the Jewish world. Most of his works have been lost over time, but his best-known work, Emunot v'De'ot, which was the first systematic work of Jewish philosophy, is still extant and popularly studied to this day. His ground-breaking work in Hebrew grammar was part of his polemic against Karaism. Parts of his commentaries to Torah and Talmud have been preserved in books written by other Geonim, some of which have recently been published. He was the first Torah sage to write extensively in Judeo-Arabic.
Samson Raphael Hirsch was a German scholar, rabbi, activist and pioneer of the Torah Im Derekh Eretz school of contemporary Orthodox Judaism. He received both a general and religious education as a youth, the latter taking place under the mentorship of Chacham Isaac Bernays and Rabbi Jacob Ettinger. He began studies at the University of Bonn but did not obtain a degree. At the age of 22 he became the Chief Rabbi of Oldenburg. Within 8 years he had published both his "Nineteen Letters of Ben Uziel" and "Horeb", together presenting compelling intellectual explications of Orthodoxy and a defense of its precepts and institutions. He also served as rabbi in Emden, Nikolsburg (Moravia), and Frankfurt am Main. In each post he used his considerable skills as an orator and writer to promote an Orthodoxy that could withstand the relentless challenge of the Reform movement. As Chief Rabbi of Moravia, he was politically active in the ultimately successful struggle for Jewish emancipation. Later, he was largely responsible for convincing the Prussian parliament to permit Jews to secede from the official state-recognized Jewish religious community, allowing break-off congregations to preserve their traditional, Orthodox character. His greatest legacy, however, is his philosophy of Torah Im Derekh Eretz, synthesizing Torah learning with secular learning, particularly of the sciences. His influence reached far beyond Germany, and his Torah commentary, which has been translated from the original German to Hebrew and English, is widely studied and often quoted.
12-13th century French Tosafist, also known by the acronym "Rash" or "Rashba" (not to be confused with R' Shlomo ben Aderet). Born in France, he first studied under Rabbeinu Tam, and later under Rabbeinu Yitzchak (Ri HaZaken) who was his primary teacher. Rosh considers him to be the preeminent Baal Tosafot after Rabbeinu Tam and Ri. Many of the Tosafot which are printed in our Talmud are either taken from Rash's work, "Tosafot Shantz", or based on them. Rash's commentary on Mishnayot Zeraim and Taharot, on which there is no Talmud, is printed along with Rambam's commentary in the Vilna Shas. In 1211, Rash joined a group of 300 French and English scholars who emigrated to Israel in order to escape the persecution of Jews taking place in their countries. He lived in Jerusalem, earning him the title "Ish Yerushalayim", and is buried in Akko (Acre).
Samuel ben Uri Shraga Phoebus was a Polish rabbi and Talmudist of Woydyslaw in the second half of the 17th century. In his early youth he was a pupil of Rabbi Heshel in Cracow, and on the latter's death he continued his studies under R. Heshel's successor, Rabbi Leib Fischeles, whose daughter he married. Samuel officiated as rabbi in Shydlow, Poland, whence he was called in September 1691 to the rabbinate of Fürth, Germany. The reason is not known; but he longed for his former rabbinate and returned to his former position in 1694. Samuel wrote a clear and comprehensive commentary, known as "Beit Shmuel", on the Shulhan Arukh Even ha'Ezer, which appeared in Dyhernfurth in 1689. However, being that he did not have with whom to discuss his work while he was first writing it, he later thoroughly revised it while serving as Rabbi in in Fürth, where he had the opportunity to collaborate with other scholars, and released a second edition in 1694. He wrote also several responsa and opinions, one of which is published in Ḥinnukh Bet Yehudah, No. 131. His daughter married R. Aaron Hart, the chief rabbi of the United Kingdom.
One of the greatest sages and Halakhic authorities of Salonika in the 16th century. A student of R. Levi ben Haviv (Ralbach) and Rabbi Yosef Taitacz, he served as rabbi in many communities in Turkey, and the Talmudic academy he headed produced many great scholars, among them R. Avraham di Boton (author of 'Lechem Mishneh') and R. Menachem Di Lunzano. He received Halachic inquiries from Italy and the entire Balkan region, and nearly one thousand of his responsa were printed by his son as "Responsa of Maharashdam." His sermons were published under the name "Ben Shmuel", and he also wrote novellae on the Talmud, which have never been printed.
16th century Rosh Yeshiva and Kabbalist in Safed, disciple of the Arizal and R' Hayyim Vital. He established a large Yeshiva in Safed which promoted the study of Halacha and Kabbalah. His most famous work is "Midrash Shmuel" on Pirkei Avot, which contains an anthology of other commentaries along with his own insights. He also wrote commentaries on the Megillot: "Iggeret Shmuel" on Ruth, and "Lechem Dimah" on Eichah. His commentary on Esther has been recently published.
Ovadiah ben Ya'akov Seforno was an Italian rabbi, Biblical commentator, philosopher, halachic authority, and physician who wrote commentaries on a good portion of the Tanach. After an early period of wandering, he settled in Bologna, where he founded a yeshiva. Sforno was held in high regard by his contemporaries, Maharam Padua and Maharik Kolon and is also quoted in responsa of contemporary authorities who consulted him on issues of Halacha. Seforno was admired for his wide knowledge by Henry II, King of France, to whom he sent a Latin translation he prepared of his philosophical work, Or Amim.
Shabbatai Hakohen – better known as Shach, after the acronym of his most famous work – was a Lithuanian/Polish rabbi, halachic scholar and Talmudic commentator. He was raised in Vilna, and studied in Tykotzin, Cracow and Lublin. He returned to Vilna, where he married the daughter of the wealthy great-grandson of the Rema, and served in the beit din of R.

He settled in Amsterdam in 1679 after extensive travels, where he learned the printer's craft. He subsequently settled in Breslau where he set up a successful publishing/printing establishment. He was a ground-breaking bibliographer whose classification system was unprecedented at his time. In his old-age, he was falsely charged with printing works considered blasphemous by Christian authorities. As a result, he had to spend time in prison before eventually getting acquitted. His last years were devoted to revising his bibliographical work, but he died before he could complete the revision.

This highly respected work, known as "Shulchan Aruch HaRav", is considered the primary code of law for Chabad Chasidim as well as many other Chasidic groups. His best-known work is the vastly influential Likkutei Amarim, better known as the "Tanya", a systematic presentation of Chasidic philosophy, considered to be a core Chasidic text. His other works on Chassidut, all of which draw heavily on Kabbalah, are "Torah Ohr", "Likutei Torah", "Sefer HaMaamarim", and a commentary on daily prayers. He also composed some popular melodies.

The Tosafists - Ba'alei HaTosafot - were members of a school of Torah and Talmudic interpretation which flourished in 12th and 13th century France and Germany. Their roots are in the work of Rashi – in fact Rashi's sons-in-law and grandsons are counted amongst the founders and most influential members of the school of Tosafot. Their comments on almost every tractate of the Talmud were collected, edited, augmented and passed on for generations, with certain collections gaining more prominence (depending on tractate and locale). Their approach is analytical, comparative and incisive, and many times takes a critical stance regarding Rashi's commentary. They were amongst the first French and German rabbis to quote extensively the Jerusalem Talmud and the Talmud commentary of Rabbenu Chananel (of North Africa). Other works also emerged from their school, most notably Machzor Vitri and the Torah commentary, Da'at Z'kenim.

He wrote copious commentaries on virtually all Jewish texts, including corrective notes on the Talmud. He also authored books on grammar and mathematics and encouraged his students to learn the secular sciences. He may be best remembered as one of the leaders of the "Misnagdim," the opponents of the newly emergent Hasidic movement.

Mecklenberg was a businessman until the age of 46, when he was offered and accepted the position of rabbi in Konigsberg, East Prussia. The Jews of Konigsberg were being influenced by the Haskalah, which he strongly opposed. His Torah commentary which he wrote at this time, Haketav Vehakabbalah, attempted to refute the reformers by demonstrating the close connections between Rabbinic law and Biblical text. Together with the Malbim, he publicly denounced the Reform Judaism's 1844 Braunschweig convention. He continued to serve as Rabbi of Konigsberg for 34 years, until his death.
Jacob Weil, later known as Mahariv (Hebrew: יעקב בן יהודה ווייל) was a German rabbi and Talmudist who flourished during the first half of the fifteenth century. He was one of the foremost pupils of Jacob Moelin (Maharil), who ordained him in the rabbinate, and authorized him to officiate in Nuremberg. Weil, however, did not avail himself of this permission lest he should offend an older scholar, Solomon Cohen, who had been appointed rabbi of that city long before. Weil was later called to the rabbinate of Erfurt; and congregations far and near, recognizing him as an authority, addressed their problems to him. Of Weil's works only a collection of opinions and decisions, "She'elot u-Teshubot", has been preserved. To this work was added an appendix entitled "Sheḥiṭot u-Bediḳot," containing regulations for slaughtering and for the examination of slaughtered cattle. These rules have been regarded as authoritative by later rabbis, have run through seventy-one editions, and the responsa have been the subjects of various commentaries and additions.

In 1744 he married Gitel, daughter of Jacob Eger, a well-to-do resident of Prague. The expulsion of the Jews from Prague led him to Metz in 1745, where he remained until 1748, continuing his studies under Jonathan Eybeschütz. In 1770 he succeeded his father as rabbi of Carlsruhe. His will shows him to have been a man of great piety who was particularly knowledgeable in Kabbalah. He authored many works, only one of which he printed: "HaMarbeh L'Sapeir", a commentary on the Passover Haggadah.

Landau was highly esteemed not just by the community, but also by others; and he stood in high favour in government circles. Thus, in addition to his rabbinical tasks, he was able to intercede with the government on various occasions when anti-Semitic measures had been introduced. Though not opposed to secular knowledge, he objected to "that culture which came from Berlin", in particular Moses Mendelssohn's translation of the Pentateuch. He authored responsa Noda Biyhuda (named in honor of his father, Yehuda), and a commentary on Talmud entitled "Tzion L'Nefesh Chaya" (named in honor of his mother, Chaya), or "Tzelach" for short.

Yehuda Halevi was a Spanish poet and philosopher. He is considered to this day to be one of the greatest Hebrew poets of all time, and his liturgical poetry appears in several prayer rites. He had a comprehensive education, including both secular and Torah subjects. Many are of the opinion that he was a direct student of the Rif. He also served as court physician to the king of Castile, and due to an enthusiastic patron, was well-received in wide circles. He was especially close to the Ibn Ezra, who quotes him a number of times in his commentaries. His philosophical work, the Kuzari, is one of the great masterpieces of Jewish philosophy. He felt a particularly strong yearning for the Land of Israel towards the end of his life, leading him to travel first to Egypt where he stayed for a bit and then to board a boat to Israel. Although legend attributes his demise to the hooves of a military mount in Jerusalem, there is no conclusive contemporary evidence as to what befell him and whether he actually reached the Land of Israel.

Yehudah Aryeh Leib Alter (the Sefat Emet) was a Polish rabbi and Chassidic master, third rebbe of the Gerer Chassidim. His father died while he was still a boy and he was raised by his grandfather, the Chiddushei HaRim. He also served as head of the town's beit din. Upon his grandfather's passing in 1866, he refused to fill his position, instead choosing to submit himself to the leadership of R' Chanoch Henoch of Alexander. When the Rebbe of Alexander passed away in 1870, he reluctantly accepted the leadership of the Gerrer chassidim. Under his leadership, Ger became the largest and most influential Chassidic court in Poland. His many works were all posthumously called Sefat Emet, and they include a magisterial collection of chassidic insight and teachings based on the weekly Torah portion, as well as a scholarly commentary on Talmud. These works are widely studied throughout the Jewish world to this day. Unlike many Chassidic masters, he refused to accept money willingly given by his followers, and supported himself from a small store run by his wife. Although he encouraged the building and settling of the Holy Land, he was an opponent of the nascent Zionist movement. He died in 1905 and was succeeded by his eldest son, Avraham Mordechai (Imrei Emet).

Israel Bruna (ישראל ברונא) was a German rabbi and Posek. He is also known as Mahari Bruna, the Hebrew acronym for "Our Teacher, the Rabbi, Israel Bruna". He studied under the leading Ashkenazi rabbis of his time: Jacob Weil and Israel Isserlin, who ordained him and spoke very highly of him. He was then elected rabbi of Brno. After the expulsion of the Jews from that city (1454) he settled at Ratisbon, Bavaria, where he opened a yeshivah. His position in Ratisbon caused some controversy, dividing the community. Rabbi Anschel Segal, who already was operating a yeshivah there, felt Rabbi Bruna should have opened his yeshivah elsewhere. However, upon the death of Rabbi Segal he was accepted by the whole community. Rabbi Bruna was one of the greatest Talmudic authorities of his time: rabbis and scholars from various cities and countries sent him their queries on all matters relating to Jewish law. These responsa, Teshuvot Mahari Bruna, are his best known work. Importantly, they served as a source of Halakha for Moses Isserles' HaMapah - the gloss on the Shulkhan Arukh describing differences between Ashkenazi and Sephardi practice.
