Theodore Herman Albert Dreiser (; August 27, 1871 – December 28, 1945) was an American novelist and journalist of the naturalist school. His novels often featured main characters who succeeded at their objectives despite a lack of a firm moral code, and literary situations that more closely resemble studies of nature than tales of choice and agency. Dreiser's best known novels include Sister Carrie (1900) and An American Tragedy (1925).
