NAḤMAN BEN ḤAYYIM HA-KOHEN:
French tosafist; flourished toward the end of the twelfth century. As Gross concludes from "Kol Bo" (ed. Venice, 1562), No. 101, Naḥman was the son of Ḥayyim ben Hananeel ha-Kohen. He was the author of "Sefer Naḥmani," which Joseph Colon quotes (Responsa, ed. Lemberg, 1798, Nos. 145, 149). Gross identifies him further with the tosafist Naḥman, whose tosafot are mentioned in "Shiṭṭah Meḳubbeẓet" to B. Ḳ. 43a (Venice, 1762).
