Heinrich Mann's novel about a despotic teacher, which was the basis of the movie The Blue Angel.
This novel provides examples of:
- Appropriated Appellation: Unrat's nickname, after he gains dubious power over the town.
- Brilliant, but Lazy: Lohmann, who slacks off studying and educates himself instead, but still would get good grades if Unrat graded him justly.
- Despotism Justifies the Means: For Unrat, ruining the former disobedient students is worth ruining his own fortune and allowing his wife to cheat on him.
- Devoted to You: Ertzum to Rosa.
- Embarrassing Nickname: The basis of the Professor's mania, hatred and tyranny towards his students is the nickname "Unrat" ("Garbage"), which is completely justified in-universe: he is described as very ugly, disheveled, prematurely aged, rather incompetent and a failure in anything including his own former marriage.
- Fiery Redhead: Rosa.
- Forbidden Fruit: Lohmann for Rosa.
- I Love You Because I Can't Control You: Rosa for the immune Lohmann.
- In Love with Love: Lohmann.
- Loving a Shadow: Ertzum, loving Rosa for reminding him of a peasant girl, who made him a man.
- Married to the Job: Unrat to the school, later to seizing power on the town.
- Nouveau Riche: The reason for which the wealthy men of the town are so easily ensnared and swindled in Unrat's gambling ring.
- Really Gets Around: Rosa.
- Sadist Teacher: Unrat is a petty tyrant who hates all of his students, and delights in punishing them or giving them bad grades.
- Sleeps with Everyone but You: Rosa is a cheap hooker but she wouldn't be with Ertzum for his whole inheritage. Justified in-universe by the fact Ertzum—despite his aristocratic standing—is extremely stupid and boorish, so stupid he makes the Professor appear brilliant by comparison.
- The Trickster: Kieselack.
- Unholy Matrimony: Unrat and Rosa.
- Upper-Class Twit: Von Ertzum is a Count.
