Mosheh ben Maimon (1135 - December 12, 1204) was a preeminent medieval Spanish, Sephardic Jewish philosopher, astronomer and one of the most prolific and influential Torah scholars and physicians of the Middle Ages. He is acknowledged to be one of the foremost rabbinical arbiters and philosophers in Jewish history, his copious work comprising a cornerstone of Jewish scholarship. His Mishneh Torah, the first systematic code of Jewish religious law, was compiled between 1170 and 1180. His Guide To The Perplexed (1190), is a study of the Jewish religion, that had a profound influence on Jews and Christians alike. He also wrote on mathematics and medicine and became the personal doctor to the Muslim general Saladin, sultan of Egypt. He died in 1204 at the age of 69.
