Georg Simmel (gā´ôrk zĬm´əl), 1858–1918, German philosopher and sociologist. At the universities of Berlin and Strasbourg he was an influential lecturer. Basing his social philosophy on a broad historical foundation, he did much to establish German sociology as an independent discipline. His chief works are Soziologie (1908) and Lebensanschauung [philosophy of life] (1918).
