R' Moshe ben Yaakov (Sefer HaTerumah)

R' Moshe ben Yaakov was a 12th-century Ashkenazi halakhic authority known for his comprehensive halakhic work, the Sefer HaTerumah, which systematically organized Jewish law by topic. His work became influential in the development of Ashkenazi jurisprudence and served as a source for later codifiers including the Tur and Shulchan Aruch. The Sefer HaTerumah demonstrates deep engagement with Talmudic sources and earlier Geonic and Franco-German rabbinic traditions.
