Notorious American gangster Al Capone spent 4½ years in the prison on Alcatraz Island after being transferred there in August 1934 from the Federal Penitentiary in Atlanta.
Capone was serving an 11-year sentence for tax evasion, during which time his mental health seriously declined due to syphilis contracted prior to his incarceration.
He spent his final year at Alcatraz on the prison’s hospital wing before being transferred in January 1939, aged 39, to the prison at Terminal Island, Los Angeles.
