Louis Aragon was born in Paris, France. He had a varied professional life that included experimentation with numerous writing styles. Initially planning on a career in medicine, Aragon studied at the University of Paris. During World War I and World War II, he was mobilized as an auxiliary doctor. Dadaism and surrealism influenced many of his early works, including Nightwalker. In 1919 he co-founded the Surrealist magazine Literature, but he soon broke away from dadaism and surrealism and joined the Communist Party. Among his best-known works are Residential Quarters and The Bells of Basel, which reflect this Communist influence. His later works, such as Holy Week (1958), seem to turn away from some of his more controversial ideas. In the 1940s Aragon reintroduced rhyme in his work and was interested in ideas of automatic writing and freedom of the unconscious. Aragon wrote under numerous pseudonyms including Albert de Routisie, Arnaud de Saint Roman, and Francois La Colere. He died on December 24, 1982.
