Jack Gilbert (February 18, 1925 – November 13, 2012) was an American poet. Born and raised in the Pittsburgh, Pennsylvania neighborhood of East Liberty, he attended Peabody High School before failing out. Gilbert then worked as a door-to-door salesman, an exterminator, and a steelworker. Due to a clerical error, he was admitted to the University of Pittsburgh and graduated in 1954. During these college years he and his classmate Gerald Stern developed a serious interest in poetry and writing. Later, he received his master's degree from San Francisco State University in 1963.
