1625 - 1693 (10 Adar 5453) GERSHON ASHKENAZI (Austria)
Rabbi and preacher. Ashkenazi served as chief Rabbi of Austria until the expulsion of 1670. His responsa, Avodat HaGershuni dealt with a wide range of Halacha. Much of what we know about the Chmielniki massacres are based on this work. A prolific writer, he also composed Tiferet HaGershuni, which was comprised of his sermons on the Torah, and Chidushei HaGershuni on Halacha.
