Thomas Mann (6 June 1875  12 August 1955) was a German novelist, short story writer, social critic, philanthropist, essayist, and 1929 Nobel Prize laureate, known for his series of highly symbolic and ironic epic novels and novellas, noted for their insight into the psychology of the artist and the intellectual. His analysis and critique of the European and German soul used modernized German and Biblical stories, as well as the ideas of Goethe, Nietzsche, and Schopenhauer. His older brother was the radical writer Heinrich Mann, and three of his six children, Erika Mann, Klaus Mann and Golo Mann, also became important German writers. When Hitler came to power in 1933, the anti-fascist Mann fled to Switzerland. When World War II broke out in 1939, he emigrated to the United States, from where he returned to Switzerland in 1952. Thomas Mann is one of the most known exponents of the so called Exilliteratur.
