Question: Which novelist wrote the novel "Little Big Man", Thomas Berger or Thomas Keneally?

full_context: Document 1: Arthur Rex: Arthur Rex: A Legendary Novel is a 1978 novel by American author Thomas Berger. Berger offers his own take on the legends of King Arthur, from the heroic monarch's inauspicious conception, to his childhood in bucolic Wales, his rise to the throne, his discovery of the great sword Excalibur, his establishment of the Knights of the Round Table, his long and honorable reign, and his heroic death in battle against the evil Mordred, his bastard son.
Document 2: Tom Robbins: Thomas Eugene "Tom" Robbins (born July 22, 1932) is an American novelist. His best-selling novels are "seriocomedies" (also known as "comedy-drama"), often wildly poetic stories with a strong social and philosophical undercurrent, an irreverent bent, and scenes extrapolated from carefully researched bizarre facts. His novel "Even Cowgirls Get the Blues" was made into a movie in 1993 by Gus Van Sant and stars Uma Thurman, Lorraine Bracco, and Keanu Reeves.
Document 3: Louis L'Amour: Louis Dearborn L'Amour ( ; March 22 1908 –June 10 1988) was an American novelist and short story writer. His books consisted primarily of Western novels (though he called his work 'frontier stories'); however, he also wrote historical fiction ("The Walking Drum"), science fiction ("The Haunted Mesa"), non-fiction ("Frontier"), as well as poetry and short-story collections. Many of his stories were made into films and John Wayne once made the dubious assertion that L'Amour was the most interesting man in the world. L'Amour's books remain popular and most have gone through multiple printings. At the time of his death almost all of his 105 existing works (89 novels, 14 short-story collections, and two full-length works of nonfiction) were still in print, and he was considered "one of the world's most popular writers".
Document 4: Oskar Schindler: Oskar Schindler (28 April 1908 – 9 October 1974) was a German industrialist, spy, and member of the Nazi Party who is credited with saving the lives of 1,200 Jews during the Holocaust by employing them in his enamelware and ammunitions factories, which were located in occupied Poland and the Protectorate of Bohemia and Moravia. He is the subject of the 1982 novel "Schindler's Ark" and its 1993 film adaptation, "Schindler's List", which reflected his life as an opportunist initially motivated by profit, who came to show extraordinary initiative, tenacity, and dedication to save the lives of his Jewish employees.
Document 5: Little Big Man (novel): 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."
Document 6: Schindler's Ark: Schindler's Ark (released in America as Schindler's List) is a Booker Prize-winning historical fiction novel published in 1982 by Australian novelist Thomas Keneally, which was later adapted into the highly successful movie "Schindler's List" directed by Steven Spielberg. The United States version of the book was called "Schindler's List" from the beginning; it was later re-issued in Commonwealth countries under that name as well. The novel was also awarded the Los Angeles Times Book Prize for Fiction in 1983.
Document 7: Thomas Berger (novelist): 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.
Document 8: Thomas Mallon: Thomas Mallon (born November 2, 1951) is an American novelist, essayist, and critic. His novels are renowned for their attention to historical detail and context and for the author's crisp wit and interest in the "bystanders" to larger historical events. He is the author of nine books of fiction, including "Henry and Clara", "Two Moons", "Dewey Defeats Truman", "Aurora 7", "Bandbox", "Fellow Travelers", "Watergate", and most recently "Finale". He has also published nonfiction on plagiarism ("Stolen Words"), diaries ("A Book of One's Own"), letters ("Yours Ever") and the Kennedy assassination ("Mrs. Paine's Garage"), as well as two volumes of essays ("Rockets and Rodeos" and "In Fact").
