Theodor Wiesengrund Adorno (1903-1969) – German philosopher of Jewish origin, a sociologist and music theorist, and one of the main representatives of the »critical theory«. In the 1920s and 1930s, he published essays in the journal Zeitschrift für Sozialforschung. In 1938 Max Horkheimer, the Director of the Social Research Institute, invited him to emigrate and he joined other representatives of the Frankfurt School in New York City. There he worked on The Enlightenment Dialectics. Philosophical Fragments. In 1949 he returned to Frankfurt, Germany, and as a deputy director, greatly contributed to the re-establishment of the Social Research Institute. As a representative of the older generation, Adorno was actively involved in the student movement of 1968. His theories are based largely on the teachings of Hegel, Marx and Freud. Adorno’s criticism is mainly aimed at domination in modern society, authoritarianism, anti-Semitism and the near disappearance of the possibility of achieving human happiness. He worked closely with Max Horkheimer, Siegfried Kracauer and Walter Benjamin. His main works are Negative Dialectics, Aesthetic Theory, Minima Moralia: Reflections from Damaged Life.
