Weird to say, but Ed Gein is the most influential serial killer ever to emerge from the underground. The inspiration of Psycho, Buffalo Bill (Silence of the Lambs) and Leatherface... The idea it that he was the original skinner.
When his mother died in 1945, Gein was left alone and began to obsess over sex and the woman anatomy. A friend named Gus told Ed about the experiments he wanted to perform an women, so together, they began to rob graves. This hobby went on for ten years, and the experiments became more and more bizarre. One of the grave robberies was of Gein's own mother's grave.He was obsessed with becoming a woman, and so would drape the skin, breasts, and faces on his body. He even made a full size woman-skin jumpsuit. Technically, Gein only killed two women, and he was caught immediately after the second murder. He was recognized as criminally insane and was sentenced to life in a mental institution.
He was a manipulator who preached religion to attract and brainwash young women with troubled histories. Manson gained followers, adopting them into what became known as "The Family," who all lived in a movie ranch owned by George Spahn. The women began to call Manson 'Jesus Christ' and would do anything for him, including sexual favors. He brainwashed them into believing that African-Americans would gain power, kill all the white families, and that the Manson Family will be the only white family left alive. All of this was revealed to him through Beatles records, particularly the song "Helter Skelter."Though there is no evidence that he ever killed anyone himself, Manson was found responsible for all seven murders done by the Manson Family and of conspiracy to commit murder. He has been in prison since 1971.
