Jean Keraudy was the stage name of Roland Barbat. He was known for his multiple prison escapes, most notably from France's La Santé Prison.
He served as the inspiration for the character of Roland Darban in José Giovanni's 1957 novel The Hole (French: Le Trou). The two met while cellmates.
In the 1960 film production of The Hole, director Jacques Becker cast him to play Darban.
He died in 2001.
