Thomas Louis Berger was an American novelist, best known for his picaresque novel Little Big Man, which was adapted into a film by Arthur Penn. Berger explored and manipulated many genres of fiction throughout his career, including the crime novel, the hard-boiled detective story, science fiction, the utopian novel, plus re-workings of classical mythology, Arthurian legend, and the survival adventure. Berger's use of humor and his often biting wit led many reviewers to refer to him as a satirist or "comic" novelist, though he rejected that classification.
