German Jewish scholar.
After studying in France, he served as rabbi in several communities in Germany, notably Rothenburg, where he opened a Talmudic school. He became famous as an authority on rabbinic law, writing notes and commentary on the Talmud and acting for nearly half a century as the supreme court of appeals for Jews of Germany and surrounding countries. Persecution prompted him to flee Germany with a group of followers in 1286, but he was caught and imprisoned for the rest of his life in an Alsatian fortress.
