Great choices both of you!!! I was going to go with Ian Anderson, but you beat me to it.
I've got an interesting one today. Alvin "Creepy" Karpis, is know for having the longest sentence of anybody at Alcatraz.
I found this on wikipedia, thought it was a n interesting read.
Sentenced to life imprisonment, Karpis was incarcerated at the recently formed Alcatraz federal penitentiary from August 1936 to April 1962. For six months in 1958, he had been transferred to the
Leavenworth federal penitentiary, but was then returned to Alcatraz. His main job at Alcatraz was working at the bakery. He was far from a model prisoner, frequently fighting with other inmates. However, Karpis is renowned for being the prisoner with the longest sentence at Alcatraz, yet the only prisoner with no escape attempts.
[citation needed] In April 1962, with Alcatraz in the process of being closed, he was transferred to
McNeil Island Penitentiary in
Washington state. While at McNeil he met a young inmate named
Charles Manson. Karpis wrote about Manson in his autobiography with Robert Livesey, published in 1980):
"
This kid approaches me to request music lessons. He wants to learn guitar and become a music star. 'Little Charlie' is so lazy and shiftless, I doubt if he'll put in the time required to learn. The youngster has been in institutions all of his life--first orphanages, then reformatories, and finally federal prison. His mother, a prostitute, was never around to look after him. I decide it's time someone did something for him, and to my surprise, he learns quickly. He has a pleasant voice and a pleasing personality, although he's unusually meek and mild for a convict. He never has a harsh word to say and is never involved in even an argument."
After Manson had actually become somewhat proficient on the
guitar, he asked Karpis for help in getting a job playing in
Las Vegas as Karpis had contacts with nightclub and
casino owners there. Manson even told him he would be bigger than the
Beatles, but in the end Karpis decided to leave Manson on his own regarding his music career. Manson was moved to a
Los Angeles facility in 1967, which proved to be one of the most ominous
prison transfers ever. Later Karpis added "The history of crime in the United States might have been considerably altered if 'Little Charlie' had been given the opportunity to find fame and fortune in the music industry. He later became the infamous Charles Manson."
