Many of the most dangerous criminals in the United States were sent to Alcatraz Federal Penitentary to serve their sentences. Al Capone, George Kelly and Robert Stroud were three of the well known convicts that spent time on "the rock". While two of the three used bullets, Robert Stroud handled birds and wasn't as handsome as Burt Lancaster who portrayed Stroud in the 1962 film The Birdman of Alcatraz.
