Ramban
Rav Moshe the son of Nachman was born in Gerona, Spain in 1194. He is perhaps best known for his two major commentaries - his commentary on the Chumash, which both interprets the verses and discusses the topic in a broader spectrum, and his commentary on the Talmud, written in the style of the Tosafists. In addition, he wrote two works defending Rif, namely his Milchamot Hashem, which answered the charges of the Baal HaMaor, and the Sefer Ha-Zechut, which defended Rif from Raavad. He also wrote several smaller works on specialized topics. In 1263 he was ordered by the king of Aragon to participate in a religious disputation with Pablo Christiani, a Jewish apostate. Ramban won the debate, and published an account of the proceedings. However, the Dominicans showed the king several passages that were deemed to be blasphemies against Christianity, and the work was burned. Ramban ultimately moved to Israel, settling in Acco until his death in 1270. His students included both Raah and Rashba.
