Theodore Dreiser, 1871-1945, was an American novelist and journalist. He was born the twelfth of thirteen children in Terre Haute, IN and attended Indiana University in Bloomington briefly before dropping out in 1890. He married Sara White in 1898, and they separated in 1909 although never formally divorced. Dreiser became a renowned author of literary naturalism (other American writers in the movement included Jack London, Edith Wharton, Frank Norris, and Stephen Crane). His best known novels are Sister Carrie (although a commercial failure at the time in 1900), Jeannie Gerhardt (1911), and An American Tragedy (1925). Politically, Dreiser was involved in socialist causes and wrote a non-fiction book, Dreiser Looks at Russia (1928), based on his experiences visiting the Soviet Union. He did not officially join the American Communist Party until shortly before his death in 1945.
