Mosheh ben Maimon (משה בן מימון), called Moses Maimonides and also known as Mūsā ibn Maymūn (Arabic: موسى بن ميمون), or RaMBaM (רמב"ם – Hebrew acronym for "Rabbi Mosheh Ben Maimon"), was a preeminent medieval Jewish philosopher and one of the most prolific and followed Torah scholars and physicians of the Middle Ages. He was born in Córdoba, Almoravid Empire (present-day Spain) on Passover Eve, 1135, and died in Egypt (or Tiberias) on 20th Tevet, December 12, 1204.[5] He was a rabbi, physician, and philosopher in Morocco and Egypt.

Although his writings on Jewish law and ethics were met with acclaim and gratitude from most Jews even as far off as Spain, Iraq and Yemen, and he rose to be the revered head of the Jewish community in Egypt, there were also vociferous critics of some of his rulings and other writings particularly in Spain. Nevertheless, he was posthumously acknowledged to be one of the foremost rabbinical arbiters and philosophers in Jewish history, his copious work a cornerstone of Jewish scholarship. His fourteen-volume Mishneh Torah still carries canonical authority as a codification of Talmudic law. In the Yeshiva world he is known as "haNesher haGadol" (the great eagle) in recognition of his outstanding status as a bona fide exponent of the Oral Torah.

The Guide for the Perplexed (Hebrew: Moreh Nevuchim, Arabic: dalalat al ha'irin) is one of the major works of Rabbi Moshe ben Maimon, better known as Maimonides, or the Rambam. It is the main source of his philosophical views. The main purpose of the work is to expound on Maaseh Bereishit and Maaseh Merkavah (the sections of Jewish mysticism dealing with Creation from Genesis and the passage of the Chariot from Ezekiel), these being the two main mystical texts in the Tanakh.
