William Berger, also known as Bill Berger and Wilhelm Berger, born Wilhelm Thomas Berger (June 20, 1928-October 2, 1993) was an Austrian American actor, mostly associated with Euro and spaghetti Westerns, as well as travel documentaries.
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.
 Berger's biting wit led many reviewers to refer to him as a satirist or "comic" novelist, descriptions he preferred to reject.
 His admirers often bemoaned that his talent and achievement were under-appreciated, in view of his versatility across many forms of fiction, his precise use of language, and his probing intelligence.

 This proposed pipeline became known as the Mackenzie Valley Pipeline.

Little Big Man is a 1964 novel by American author Thomas Berger.
 Often described as a satire or parody of the western genre, the book is a modern example of picaresque fiction.
 Berger made use of a large volume of overlooked first-person primary materials, such as diaries, letters, and memoirs, to fashion a wide-ranging and entertaining tale that comments on alienation, identity, and perceptions of reality.
 Easily Berger's best known work, "Little Big Man" was made into a popular film by Arthur Penn.
 It has been called "Berger's response to the great American myth of the frontier, representing as it does most of the central traditions of American literature."
