R. Baruch of Worms

R. Baruch ben Yitzchak of Worms (c. 1140-1211) was a leading second-generation Tosafist and the author of Sefer HaTerumah — one of the most widely-studied Tosafist halachic codes. The work covers the laws of Shabbat, Niddah, forbidden foods (issur ve-heter), Avodah Zarah, and Sefer Torah, structured around the relevant Talmudic discussions with extensive citations of the early Tosafist tradition. Together with the Mordechai and the Or Zarua, the Sefer HaTerumah is one of the three foundational halachic codifications of the Tosafist school.
