Herbert Marcuse was a German-American philosopher, social critic, and political theorist, associated with the Frankfurt School of critical theory. Born in Berlin, Marcuse studied at the Humboldt University of Berlin and then at Freiburg, where he received his PhD. He was a prominent figure in the Frankfurt-based Institute for Social Research – what later became known as the Frankfurt School. In his written works, he criticized capitalism, modern technology, Soviet Communism, and popular culture, arguing that they represent new forms of social control.

The Frankfurt School is a school of thought in sociology and critical philosophy. It is associated with the Institute for Social Research founded at Goethe University Frankfurt in 1923. Formed during the Weimar Republic during the European interwar period, the first generation of the Frankfurt School was composed of intellectuals, academics, and political dissidents dissatisfied with the contemporary socio-economic systems of the 1930s: namely, capitalism, fascism, and communism.
