Thomas Louis Berger (July 20, 1924 – July 13, 2014) was an American novelist. Probably best known for his picaresque novel Little Big Man and the subsequent 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.
