Born in 1934, Oskar Negt is one of Germany’s most important social scientists. He studied under Max Horkheimer, wrote his doctorate in philosophy under Theodor W. Adorno and also completed a degree in sociology. From 1962 to 1970 Negt worked as assistant to Jürgen Habermas, and he was a spokesperson of the extra-parliamentary opposition during the student movement of 1968. Between 1970 and 2002 Negt was professor for sociology in Hanover, and in 2011 he was honoured with the August-Bebel-Preis for his political engagement. In 2016 Steidl published his written oeuvre in twelve comprehensive volumes.
