Theodor W. Adorno (born Theodor Ludwig Wiesengrund; 1903 – 1969) was a German sociologist, philosopher and musicologist known for his critical theory of society. He was a leading member of the Frankfurt School of critical theory, whose work has come to be associated with thinkers such as Ernst Bloch, Walter Benjamin, Max Horkheimer and Herbert Marcuse, for whom the work of Freud, Marx and Hegel were essential to a critique of modern society.
