Who Was Moses Maimonides (Rambam)?

Rabbi Moshe ben Maimon, known to the Western world as Maimonides and in Jewish tradition by the acronym Rambam (1138–1204), was a Sephardic philosopher, physician to the Egyptian royal court, communal leader, and jurist. His Mishneh Torah reorganized the entire corpus of biblical and rabbinic law into a lucid, encyclopedic 14-volume code, while his philosophical masterwork, The Guide for the Perplexed, profoundly influenced Christian scholastics (such as Thomas Aquinas) and modern philosophers (such as Spinoza).
