How Prisoners Arrived at Alcatraz

Alcatraz Federal Penitentiary (1934–1963) housed America's most notorious criminals—Al Capone, "Machine Gun" Kelly, Robert Stroud—in a fortress on a rocky island in San Francisco Bay.

The Transfer Process

1. Selection: Inmates were transferred from other federal penitentiaries (e.g., Leavenworth, Atlanta) or, less commonly, state prisons. A few were extradited from abroad.
2. Transport to San Francisco: Prisoners traveled by train (often in locked cars) to San Francisco under heavy guard.
3. Processing: At the federal courthouse, they were fingerprinted, photographed, and issued Alcatraz regulations.
4. The Boat Ride: A short but rough launch across the bay (1.25 miles) to the island's dock. Many suffered seasickness in the choppy, cold waters.
5. Intake: Strip-searched, deloused, assigned a cell (5×9 ft, solid doors, no view), and oriented to strict routines: silence, limited privileges, counts 13+ times daily.

Why Alcatraz?

Its isolation, frigid currents, and shark-infested waters made escape nearly impossible. Of 36 escape attempts, none were confirmed successful (5 missing, presumed drowned).

Closed in 1963 due to high costs and deteriorating facilities, Alcatraz is now a National Park Service site and major tourist attraction.
