Moses ben Maimon (1138–1204), commonly known as Maimonides ( ) and also referred to by the acronym Rambam (), was a medieval Sephardic Jewish philosopher who became one of the most prolific and influential Torah scholars of the Middle Ages. In his time, he was also a preeminent astronomer and physician, serving as the personal physician of Saladin. Born in Córdoba, Almoravid Empire (present-day Spain) on Passover eve, 1138 (or 1135), he worked as a rabbi, physician and philosopher in Morocco and Egypt. He died in Egypt on 12 December 1204, whence his body was taken to the lower Galilee and buried in Tiberias.
