Ridvaz

Known universally as the Ridvaz after his Talmudic commentary *Ridvaz on Rif*, Rabbi Yaakov Dovid Wilovsky was a leading rabbinic authority and educator of the late 19th and early 20th centuries. He authored extensive supercommentaries on seminal Talmudic works including the Rif, Rosh, and Rambam, which became standard references in yeshiva study. His efforts to establish prominent yeshivos advanced Torah scholarship in both Europe and the Land of Israel.
