Nachmanides

Moses ben Nachman (Hebrew: מֹשֶׁה בֶּן־נָחְמָן Mōše ben-Nāḥmān, "Moses son of Nachman"; 1194–1270), commonly known as Nachmanides (/nækˈmænɪdiːz/; Greek: Ναχμανίδης Nakhmanídēs), and also referred to by the acronym Ramban (/ˌrɑːmˈbɑːn/; רמב״ן‎) and by the contemporary nickname Bonastruc ça Porta (Catalan: [ˌbɔnəsˈtɾuk sə ˈpɔrtə]; literally "Mazel Tov near the Gate", see astruc), was a leading medieval Jewish scholar, Catalan rabbi, philosopher, physician, kabbalist, and biblical commentator. He was raised, studied, and lived for most of his life in Girona, Catalonia. He is also considered to be an important figure in the re-establishment of the Jewish community in Jerusalem following its destruction by the Crusaders in 1099.
