John Knowles (noʊlz; September 16, 1926 - November 29, 2001) was an American novelist best known for A Separate Peace (1959).
Knowles was born on September 17, 1926, in Fairmont, West Virginia, the son of James M. Knowles, a purchasing agent from Lowell, Massachusetts, and Mary Beatrice Shea Knowles from Concord, New Hampshire. His father was a coal company executive, which earned an income that afforded the family a comfortable living. As a youth, Knowles would remark that he could write just as well as the stories from The Saturday Evening Post.
Knowles attended St. Peter's High School in Fairmont from 1938 to 1940, before he continued at Phillips Exeter Academy in Exeter, New Hampshire, and graduated in 1945. Following his time at Phillips Exeter, Knowles spent eight months serving in the US Army Air Forces at the end of World War II.
Knowles graduated from Yale University as a member of the class of 1949. At Yale, Knowles contributed stories to campus humor magazine The Yale Record and served on the board of the Yale Daily News during his sophomore, junior, and senior years, notably as editorial secretary during his senior year. He was a record-holding varsity swimmer during his sophomore year.
Early in his career, Knowles wrote for the Hartford Courant and was assistant editor for Holiday magazine. With encouragement from Thornton Wilder, he concurrently began writing novels.
Knowles died on November 29, 2001, near Fort Lauderdale, Florida.
A Separate Peace was first published in London by Secker and Warburg in 1959. Published in New York in 1960 by Macmillan, it is his most celebrated work.
The novel is based upon Knowles's experiences at Phillips Exeter Academy. The Devon School, the book's setting, is a thinly-veiled fictionalization of Exeter, with both campus and town easily recognizable. Although the plot is not autobiographical, elements of the novel stem from personal experience, including Knowles's membership in a secret society and his suffering a foot injury while he jumped from a tree during society exercises.
