Berger's literary agent, Cristina Concepcion, said Monday that he died in Nyack Hospital July 13.
One of the last major authors to have served in World War II, Berger wrote more than 20 books, including the autobiographical "Rinehart" series, a "Little Big Man" sequel and "The Feud," about warring families in a 1930s Midwest community. "The Feud" was recommended for the 1984 Pulitzer Prize by the fiction jury but was overruled by the board of directors, which awarded another Depression-era novel, William Kennedy's "Ironweed."
Berger's biggest mainstream success was "Little Big Man," published in 1964. The novel was adapted into a 1970 movie of the same name, starring Dustin Hoffman and directed by Arthur Penn. Other Berger novels made into films include "Neighbors," which starred John Belushi and Dan Aykroyd, and "Meeting Evil," featuring Samuel L. Jackson and Luke Wilson.
