The United States Disciplinary Barracks on Alcatraz was acquired by the United States Department of Justice on October 12, 1933, and the island became a Federal Bureau of Prisons federal prison in August 1934. During the 29 years it was in use, the jail held such notable criminals as Al Capone, Robert Franklin Stroud (the Birdman of Alcatraz), George "Machine Gun" Kelly, Bumpy Johnson, Rafael Cancel Miranda (a member of the Puerto Rican Nationalist Party who attacked the United States Capitol building in 1954),[22] Mickey Cohen, Arthur R. "Doc" Barker, James "Whitey" Bulger, and Alvin "Creepy" Karpis (who served more time at Alcatraz than any other inmate). It also provided housing for the Bureau of Prisons staff and their families.
