Manson set himself up as a guru in San Francisco's Haight-Ashbury. During 1967's "Summer of Love," it was becoming the most popular place for hippies to live and hang out. Preaching a philosophy that included some of the Scientology he had studied in prison, he soon had his first group of young followers, most of them female. When Manson was put in prison in July 1961 at the U.S. penitentiary in McNeil Island, Washington, he put "Scientologist" as his religion on a questionnaire.
