Norman Kingsley Mailer was an American novelist, journalist, essayist, playwright, film-maker, actor, and liberal political activist. His novel The Naked and the Dead was published in 1948 and brought him renown. His 1968 nonfiction novel Armies of the Night won the Pulitzer Prize for non-fiction as well as the National Book Award. His best-known work is widely considered to be The Executioner's Song, the 1979 winner of the Pulitzer Prize for fiction. In over six decades of work, Mailer had eleven best selling books in each of the seven decades after World War II—more than any other post-war American writer.Along with Truman Capote, Joan Didion, Hunter S. Thompson, and Tom Wolfe, Mailer is considered an innovator of creative nonfiction, a genre sometimes called New Journalism, which uses the style and devices of literary fiction in fact-based journalism.
