(1934). Four-act tragedy set in Germany in 1932 and 1933.
Professor Mamlock, a Jew and a highly respected surgeon, is forced by the enactment of anti-Semitic statutes to abandon his life's work. Mamlock is married to Ellen, a northern German Aryan. His daughter is mocked and rejected by her schoolmates, and his son Rolf, whose participation in Communist-inspired activities Mamlock condemns, risks his life to distribute flyers for underground resistance forces hostile to Nazism. A subordinate physician and a member of the German Storm Troops, Dr. Hellpach, prevents Mamlock from carrying out his duties as head physician at his own clinic and forces Mamlock's lifelong friends and colleagues to testify against the "social parasite." Betrayed and broken in spirit, Mamlock commits suicide, leaving behind Rolf and Dr. Inge, a former party member, to fight for a better world.
