Aharon HaLevi אהרן הלוי,
(1235 - 1290 CE) (1235 - 1290 לספירה)
A student of Ramban and a grandson of R. Zerachya haLevi (the Ba'al haMeor), he was involved in the Talmudic discussions of the Spanish rabbis of his time. This led him to write a gloss on Rashba's Torat HaBayit called Bedek HaBayit as well as a commentary on several volumes of the Talmud. Most scholars deny the claim that he was the anonymous author of Sefer HaChinukh.
