This article considers the German Grammar School Novel from the first half of the twentieth century an all but forgotten Germanophone prototype of campus fiction. Whereas the Anglo-American campus novel of the 1970s, 80s and 90s features university professors as future-related agents of Western counterculture and free thought, the Grammar School Novel satirizes the German grammar school teacher known as Gymnasialprofessor as a representative of the past-related order of the autocratic German state apparatus from the beginning of the twentieth century. As Heinrich Mann's 1905 novel Professor Unrat / Small Town Tyrant (the source text of Marlene Dietrich's debut movie The Blue Angel) may be considered a foundational work of the German Grammar School Novel corpus, the main part of the article offers a sample analysis of this text.
