(1898 – 1979) Philosopher and radical social critic, German-born Marcuse was one of the younger members of the neo-Marxist “Frankfurt” or “critical-theory” school. Forced out of Germany by the Nazis, he emigrated to the US in 1934, and remained in the US as a professor at the University of California, San Diego, when other members of the school returned to Germany after the Second World War. Marcuse’s writings, especially Eros and Civilization (1955) and One Dimensional Man (1964), were among the most important foundations for New Left and counterculture radicalism in the 1960s.
