Theodor W. Adorno was a German philosopher, sociologist, psychologist, musicologist, and composer 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, Erich Fromm, and Herbert Marcuse, for whom the works of Freud, Marx, and Hegel were essential to a critique of modern society. As a critic of both fascism and what he called the culture industry, his writings—such as Dialectic of Enlightenment, Minima Moralia and Negative Dialectics —strongly influenced the European New Left.
Amidst the vogue enjoyed by existentialism and positivism in early 20th-century Europe, Adorno advanced a dialectical conception of natural history that critiqued the twin temptations of ontology and empiricism through studies of Kierkegaard and Husserl.
