 In 1919 he entered Humboldt University in Berlin and took courses for four semesters. In 1920 he transferred to Freiburg to concentrate on German literature and to take courses in philosophy, politics, and economics. This period of study culminated in a doctoral dissertation entitled Der deutsche Künstlerroman (The German Artist-Novel), which was accepted in 1922 (Kellner 1984: 18). This work would be the first in a life-long engagement with aesthetics for Marcuse.
