In the winter of 1968–69 the buildings of the Institute for Social Research at the University of Frankfurt – the symbolically resonant home of what had come to be known as the Frankfurt School – were occupied by students. The police were called in, and Theodor W. Adorno, one of the great radical theorists of the twentieth century, pressed charges against a young man whose doctoral work he was supervising. Two months later, a group of women forced their way into Adorno’s lecture, handed out leaflets proclaiming that ‘Adorno as an institution is dead’, and ‘surrounded him, strewing flowers, performing a dumb show and … baring their breasts’. In action after action, the contempt of the students for the radical theorists of an older generation was made clear.
