Professor Unrat, which translates as "Professor Garbage," is one of the most important works of Heinrich Mann and has achieved notoriety through film adaptations, most notably "Der blaue Engel" (The Blue Angel) with Marlene Dietrich. The book caricatures the middle and upper class educational system of Wilhelmine Germany and the double standards of the title character. In the United States, an abridgment of the English translation was published in 1932 under the "title The Blue Angel."
