 Herbert Marcuse (1898–1979) was one of the most prominent members of the Frankfurt School or The Institute for Social Research (Institute für Sozialforschung) in Frankfurt am Main. The Frankfurt School was formed in 1922 but went into exile in the United States in the early 1930s during the reign of the Third Reich. Although most of his colleagues returned to Germany after World War II, Marcuse remained in the United States.
