From Wikipedia, the free encyclopedia. In its 29 years of operation, there were 14 acknowledged attempts to escape from Alcatraz prison involving 34 inmates (two, Joseph Cretzer and Sam Shockley, tried twice). Officially, every escape attempt failed, and most participants were either killed or quickly re-captured.
In 1962 MGM released the movie The Birdman of Alcatraz. Starring Burt Lancaster, it depicted the story of how two-time murderer Robert Stroud, originally incarcerated at Leavenworth and then transferred to Alcatraz, began to pass the time by studying the diseases of the sparrows and canaries that he kept as pets.
