Living at the time of Chmielnicki pogroms, he suffered greatly at the hand of the Cossacks, moving several times just to stay alive. Eventually he moved to Austria and different parts of Germany, serving as rabbi and head of the court in various important communities. He ended his career as rabbi and head of the court in Crakow. Due to the many Jewish men killed in the troubles, he became an expert on the topic of agunot and other related matters.
