Judah Loew ben Bezalel

Judah Loew ben Bezalel (Hebrew: יהודה ליווא בן בצלאל; between 1512 and 1526 – 17 September 1609), also known as Rabbi Loew (alt. Löw, Loewe, Löwe or Levai), the Maharal of Prague (Hebrew: מהר״ל מפראג), or simply the Maharal (the Hebrew acronym of "Moreinu ha-Rav Loew", 'Our Teacher, Rabbi Loew'), was an important Talmudic scholar, Jewish mystic, mathematician, astronomer, and philosopher who, for most of his life, served as a leading rabbi in the cities of Mikulov in Moravia and Prague in Bohemia.

Loew wrote on Jewish philosophy and Jewish mysticism. His work Gur Aryeh al HaTorah is a supercommentary on Rashi's Torah commentary. He is also the subject of a later legend that he created the Golem of Prague, an animate being fashioned from clay.
