Paul Osborn (September 4, 1901 – May 12, 1988) was an American playwright and screenwriter best known for writing the screen adaptation of East of Eden as well as South Pacific, The Yearling, The World of Suzie Wong and Sayonara.
Born and raised in Evansville, Indiana, Osborn went on to study at Yale University. He made his debut in 1928 with the play Hotbed. In 1930, he found success on Broadway with The Vinegar Tree. His 1939 original comedic play, Morning's at Seven became one of Osborn's most enduring original works. It has been presented on television, but never filmed. Revived in 1980, it would be hailed by Harold Clurman as "one of the best American comedies."
Another popular, more frequently revived Osborn play is the 1938 On Borrowed Time, which was made into an MGM film starring Lionel Barrymore, Cedric Hardwicke and Bobs Watson.
