Baal haTerumah—Rabbi Baruch ben Yitzchak רבי ברוך בן יצחק
the Tosafist who brought the French school into a code
Rabbi Baruch ben Yitzchak (c. 1140–1211), a student of the Ri haZaken, lived in Worms. The school of the Tosafot was strong in analysis and weak in conclusion: it collided passages of the Talmud but rarely carried through to "and how then does one act". Sefer haTerumah answers precisely that—the laws of the Sabbath, forbidden foods, scrolls, the writ of divorce—and so it is cited by every later codifier, from the Mordechai to the Beit Yosef.
The book also proved a bridge between countries: written in France and Germany, it passed through Provence into Spain, and the Rosh cites it, and through him the Arbaah Turim.
The sources give no exact years of life; the window of activity is set by generation, following Aharon Hyman and the lists of Seder haDorot.
