Morgan Scott Peck (23 May 1936 – 25 September 2005) was an American psychiatrist and best-selling author, best known for his first book, The Road Less Traveled, published in 1978. A graduate of the Friends Seminary, a Quaker school, he earned his undergraduate degree from Harvard College in 1958 before entering the Case Western Reserve University School of Medicine. Upon earning his M.D., he served in the U.S. Army, resigning in 1972 as a lieutenant colonel, assistant chief psychiatrist and neurology consultant to the U.S. Army surgeon general. He had a private psychiatry practice in Connecticut from 1972 to 1983.
Peck's works combined his experiences from his private psychiatric practice with a distinctly religious point of view. One of his religious insights was that people who are evil attack others rather than face their own failures. His religious views are criticized by the ultra conservatives. Peck died at his home in Connecticut on September 25, 2005. Fuller Theological Seminary houses the archives of his publications, awards, and correspondence.
