French scholar; flourished at Narbonne in the twelfth century; brother of the nasi R. Moses ben Joseph ben Merwan, and pupil of Isaac ben Merwan, head of the Narbonne academy in the early part of the twelfth century. He was held in great respect and associated with Abraham ben Isaac, ab bet din, who presided over the rabbinical college of Narbonne about 1165. According to the conjecture of Gross ("Gallia Judaica," p. 414), Meïr ben Joseph is identical with Meïr ben Jacob, who is mentioned, with the rabbinical scholars Todros ben Moses, Abraham ben Isaac, Moses ben Joseph Meshullam ben Nathan, and Moses ben Todros, at the end of a rabbinical responsum dated at Narbonne in the middle of the twelfth century.
