C. 1200 - 1263 (28 Cheshvan 5024) JONAH BEN ABRAHAM GERONDI (Spain)
Rabbi, Talmudist, and moralist. Gerondi, though an exceptional scholar, is famed as a "father of the virtues". He took to task all who were guilty of immorality, ignoring the poor, slander, and social injustice. In addition to his commentaries and novellae he is famed for his ethical works Iggeret Teshuvah (Letter of Repentance), Sefer ha-Yirah (The Book of Fear), and especially Sha'arei Teshuvah (Gates of Repentance) which has been translated into English and is widely printed today.
