Published July 1, 1926Novelist Theodore Dreiser was known for his naturalistic style, which he used in 'Sister Carrie' and 'An American Tragedy.' Dreiser was a champion of the common man, though his novels often portrayed unorthodox characters with questionable values, which caused controversy when organizations wanted to censor them. When 'Genius' was released in 1915, for example, the New York Society for the Suppression of Vice attempted to ban the book.
