Max Horkheimer was a Jewish-German philosopher and sociologist who was famous for his work in critical theory as a member of the Frankfurt School of social research. Horkheimer addressed authoritarianism, militarism, economic disruption, environmental crisis, and the poverty of mass culture using the philosophy of history as a framework. This became the foundation of critical theory. His most important works include Eclipse of Reason (1947), Between Philosophy and Social Science (1930–1938) and, in collaboration with Theodor Adorno, Dialectic of Enlightenment (1947). Through the Frankfurt School, Horkheimer planned, supported and made other significant works possible.

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.
