Mishneh Torah, The Book of Knowledge: Principles of the Torah

Born in Córdoba, Spain, Moses ben Maymūn (Abū ʿImran Mūsā ibn Maymūn ibn ʿUbayd Allāh; Moses Maimonides, also known as Rambam, an acronym of Rabbi Moses ben Maimon) was a scion of a rabbinic family and the proud heir to the Sephardic tradition of learning. After fleeing to Fez around the age of ten to escape Almohad persecutions in his homeland, he moved to Fustāt (Old Cairo), where he came to head the Jewish community and to serve as physician to the royal family. An active communal leader, Maimonides’ multifaceted contributions to Judeo-Arabic and Hebrew literature include the following: his Commentary on the Mishnah (1168), Book of the Commandments and the Mishneh Torah (both completed around 1178), Guide of the Perplexed (completed around 1190), numerous responsa, important topical essays, and a voluminous corpus of medical texts. His profound influence on virtually every subsequent Jewish thinker finds expression in the popular adage that compares Moses Maimonides to the biblical Moses himself: “From Moses to Moses there was none like Moses.”
