When you think of a prison, any prison, the first thought is how bad the people are that are inside. I mean we are talking of a population that is dangerous.

But then there was Alcatraz. A prison where the most notorious of all were send to.

Alcatraz was designed to hold prisoners who continuously caused trouble at other federal prisons. At 9:40 am in the morning of August 11, 1934, the first batch of 137 prisoners arrived at Alcatraz handcuffed and guarded by some 60 special FBI agents and U.S. Marshals.

Most of the prisoners were notorious bank robbers and murderers. So who were some of the prisoners that were in Alcatraz during it's history?

They were the worst. During the 29 years it was in use, the jail held some of the worst hoodlums America had ever known.

People such 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), Mickey Cohen, Arthur R. "Doc" Barker, James "Whitey" Bulger, and Alvin "Creepy" Karpis (who served more time at Alcatraz than any other inmate). These were some of the most dangerous people on the planet.

During its 29 years of operation, the penitentiary claimed that no prisoner successfully escaped. A total of 36 prisoners made 14 escape attempts, two men trying twice; 23 were caught, six were shot and killed during their escape, two drowned, and five are listed as "missing and presumed drowned".

Because the penitentiary cost much more to operate than other prisons, Attorney General Robert F. Kennedy ordered the penitentiary closed on March 21, 1963.
