Gibson received the 1960 Tony Award for The Miracle Worker, about the relationship between Helen Keller and her teacher, Annie Sullivan, and wrote the screenplay for the 1962 film version. He also received Tony nominations for the play Two For the Seesaw (which was later adapted into the musical Seesaw), and for the book for the musical Golden Boy, based on the play by Clifford Odets.
Gibson’s other Broadway credits included two works about Israeli prime minister Golda Meir, Golda and Golda’s Balcony, the plays Monday After the Miracle and A Cry of Players, and the book to the short-lived musical Raggedy Ann.
