Fletcher Knebel (October 1, 1911 – February 26, 1993) was an American author of several popular works of political fiction.
Knebel served in the United States Navy during World War II, attaining the rank of lieutenant.
His best-known novel is Seven Days in May (1962, co-authored with Charles W. Bailey), about an attempted military coup in the United States.
He committed suicide after a long bout with cancer, by taking an overdose of sleeping pills in his home in Honolulu, Hawaii, during 1993.
Knebel was also a staunch liberal[2] who was "suspicious of the size and power of the American military" and intelligence community, as he wrote in Dark Horse; many of his novels represented that opinion.
