Philip Sheldon Foner (December 14, 1910 – December 13, 1994) was an American Marxist labor historian and teacher. Foner was a prolific author and editor of more than 100 books, and wrote extensively on what were at the time academically unpopular themes, such as the role of radicals, blacks, and women in American history. In 1941, Foner became a public figure when he was stripped of his teaching position at City College of New York over his political views.
