John Michael Hayes (11 May 1919 – 19 November 2008) was an American screenwriter, who scripted several of Alfred Hitchcock's films in the 1950s.
Hayes was born in Worcester, Massachusetts to John Michael Hayes Sr. and Ellen Mabel Hayes. Hayes Sr. was a tool and die maker but had performed as a song and dance man on the Keith-Orpheum vaudeville circuit earlier in life.
As a child, Hayes missed much of his school career from second grade through fifth grade due to ear infections. During that time away from school, he discovered a love of reading. In junior high school, he became a staff writer on The Spectator, the school newspaper, and at age 16, he wrote for the high school yearbook as well as editing a Boy Scout weekly, The Eagle Trail. His work brought him to the attention of Worcester's Evening Gazette, and Hayes began penning articles about Boy Scout activities for the paper.
Later stints with the Worcester Telegram and a profile in The Christian Science Monitor led to a job with the Associated Press. Working diligently, Hayes managed to amass enough money to attend Massachusetts State College.
At college, Hayes became interested in radio and won a contest to write radio stories for Crosley Corporation in Cincinnati, Ohio. Following a period in the US Army during World War II, Hayes moved to California and resumed his radio career. In California, Hayes scripted for various radio comedies and dramas, including The Adventures of Sam Spade, Alias Jane Doe, Inner Sanctum Mysteries, My Favorite Husband, Sweeney and March, Twelve Players and Yours Truly, Johnny Dollar.
