University of Frankfurt Institute for Social Research in the context of "Herbert Marcuse"

Theodor W. Adorno (/əˈdɔːrnoʊ/ ə-DOR-noh; German: [ˈteːodoːɐ̯ aˈdɔʁno] ; born Theodor Ludwig Wiesengrund; 11 September 1903 – 6 August 1969) was a German philosopher, musicologist, and social theorist. 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 Sigmund Freud, Karl Marx, and G. W. F. 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 (1947), Minima Moralia (1951), and Negative Dialectics (1966)—strongly influenced the European New Left.

In an intellectual climate shaped by existentialism and logical positivism, Adorno developed a dialectical conception of history and philosophy that challenged the foundations of both, anticipating the divide that would later emerge between the analytic and continental traditions. As a classically trained musician, Adorno studied composition with Alban Berg of the Second Viennese School, influenced by his early admiration for the music of Arnold Schoenberg. Adorno's commitment to avant-garde music formed the backdrop of his subsequent writings and led to his collaboration with Thomas Mann on the latter's novel Doctor Faustus (1947), while the two men lived in California as exiles during the Second World War. Working at the newly relocated Institute for Social Research, Adorno collaborated on influential studies of authoritarianism, antisemitism, and propaganda that would later serve as models for sociological studies the institute carried out in post-war Germany.

The Frankfurt School is a school of thought in sociology and critical theory. It is associated with the Institute for Social Research founded in 1923 at the University of Frankfurt am Main (today known as Goethe University Frankfurt). 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 socio-economic systems of the 1930s: namely, capitalism, fascism, and communism. Significant figures associated with the school include Max Horkheimer, Theodor Adorno, Walter Benjamin, Erich Fromm, Wilhelm Reich, Herbert Marcuse, and Jürgen Habermas.

The Frankfurt theorists proposed that existing social theory was unable to explain the turbulent political factionalism and reactionary politics, such as Nazism, of 20th-century liberal capitalist societies. Also critical of Marxism–Leninism as a philosophically inflexible system of social organization, the School's critical-theory research sought alternative paths to social development.

Max Horkheimer (/ˈhɔːrkhaɪmər/ HORK-hy-mər; German: [ˈhɔɐ̯kˌhaɪmɐ]; 14 February 1895 – 7 July 1973) was a German philosopher and sociologist best known for his role in developing critical theory as director of the Institute for Social Research, commonly associated with the Frankfurt School.

Advancing a materialist theory of reason and society, Horkheimer analyzed the rise of instrumental reason, the erosion of the concept of truth, the decline of individual autonomy, the social-psychological roots of authoritarianism, and the reproduction of domination under modern capitalism. These concerns became fundamental to critical theory.

The concept of late capitalism (German: Spätkapitalismus), sometimes also translated as late-stage capitalism, was first used in a 1925 publication by the German social scientist Werner Sombart (1863–1941) to describe the new capitalist order emerging out of World War I. Sombart claimed that it was the beginning of a new stage in the history of capitalism. His vision of the emergence, rise and decline of capitalism was influenced by Karl Marx and Friedrich Engels’s interpretation of human history in terms of a sequence of different economic modes of production, each with a historically limited lifespan.

As a young man, Sombart was a socialist who associated with Marxist intellectuals and the German Social Democratic Party. Friedrich Engels praised Sombart’s review of the first edition of Marx’s Das Kapital Vol. 3 in 1894, and sent him a letter. As a mature academic who became well known for his own sociological writings, Sombart had a sympathetically critical attitude to the ideas of Karl Marx — seeking to criticize, modify and elaborate Marx's insights, while disavowing Marxist doctrinairism and dogmatism. This prompted a critique from Friedrich Pollock, a founder of the Frankfurt School at the Institute for Social Research. Sombart's clearly written texts and lectures helped to make "capitalism" a household word in Germany and beyond, as the name of a socioeconomic system with a specific structure and dynamic, a history, a mentality, a dominant morality and a culture.
