Ralbag

Levi ben Gershon, known as the Ralbag (an acronym for Rabbi Levi ben Gershon), was a towering fourteenth-century Provençal philosopher, mathematician, and biblical commentator active chiefly in Orange and Avignon, born in Bagnols-sur-Cèze. He produced wide-ranging works on logic, mathematics, and astronomy alongside his halakhic writings and his celebrated supercommentary on Rashi's Torah interpretations. The Ralbag was known for his bold integration of Aristotelian philosophy with Jewish thought and his willingness to challenge received interpretations when reason demanded it. He also made significant contributions to the science of his time, particularly in optics and astronomical instruments. Though sometimes controversial for his philosophical audacity, he became one of the most influential medieval Jewish intellectuals and remains a major figure in the Jewish philosophical tradition.
