Max Horkheimer (February 14, 1895 – July 7, 1973) was a German Jewish philosopher and sociologist who was famous for his work in critical theory as a member of the 'Frankfurt School' of social research. His most important works include The Eclipse of Reason (1947), "Between Philosophy and Social Science" (1930–1938) and, in collaboration with Theodor Adorno, The Dialectic of Enlightenment (1947). Through the Frankfurt School, Horkheimer planned, supported and made other significant works possible.
