Barukh ben Isaac of Worms

Barukh ben Isaac of Worms was born in France around 1140 and is sometimes referred to as Barukh ben Isaac the Frenchman (HaTzarfati). He is often confused with another Barukh ben Isaac of the same period, who was born in Worms but lived in Regensburg. A member of the Franco-German school of tosafists, he is credited as author of some portions of the Tosafot commentary printed in the Vilna edition of the Babylonian Talmud. He also wrote Sefer HaTerumah, among the first practical codes of Jewish law in Germany.
