Abigdor Cohen:

By: Louis Ginzberg

Italian rabbi, distinguished for learning and wealth, who lived in Ferrara about the middle of the fifteenth century. Joseph Kolon, the most important Talmudist of Italy at that time, speaks of him in terms of the highest respect. It can not be said with certainty that he is the author of the Vatican manuscript "Sha'are ha-Musar" (Gates of Moral Law), as Michael asserts. The name of the person to whom this manuscript is ascribed was borne by a number of medieval rabbis, and it is more probable that Abigdor Cohen of Vienna is the author; for he was held in especial honor in Rome, as may be inferred from almost every page of the "Shibbole ha-Leḳeṭ."
