Max Horkheimer (February 14, 1895 – July 7, 1973) was a German 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.
