#40: Charles Manson
Charles Manson, infamous cult leader of the Manson Family murders in the late 1960s, had a connection to Scientology during his time in prison. Long before his notoriety, he studied aspects of Scientology while incarcerated, exploring its teachings alongside other philosophies and self-help systems available to inmates.

Manson was never a church member, but his exposure to Scientology influenced his developing worldview. Prison reports suggest he practiced techniques and incorporated them into his manipulative methods. While the church distances itself from him, his brief association is often cited as a disturbing footnote in Scientology’s wider history.
