Heinrich_MannLuiz Heinrich Mann was a German novelist and elder brother of writer Thomas Mann. From his earliest writings, Mann was a social critic whose works addressed issues such as the role of the Weimar Republic in catalyzing WWI, and other human rights causes. His 1904 novel Professor Unrat was made into a movie starring Marlene Dietrich called The Blue Angel (1930).

A famous left-wing opponent of the Nazis, Mann left Germany for France before 1933. Thanks to the aid of journalist/rescuer Varian Fry, he made his way in 1940 through France, Spain, Portugal, and eventually to the U.S. He settled near his brother in Santa Monica, CA. 

Unfortunately, his writing career declined considerably during his exile, and he eventually died in his Santa Monica home.
