sentences:  The son of the Austrian-Jewish writer Ferdinand Bronner and his Christian wife Martha Bronner.Bronnen's most famous play is the Expressionist drama "Parricide" ("Vatermord", 1922); its première production is notable, among other things, for being that from which Bronnen's friend, the young Bertolt Brecht in an early stage of his directing career, withdrew, after being taken to hospital with malnutrition and the actors of the cast, led by Heinrich George, walked out on him.According to "The Cambridge Guide to Theatre", the "erotic, anti-bourgeois, black expressionism" of the play "caused a sensation" when it was eventually performed.
