Mary Ann MacClean

Mary Ann MacClean born November 20, 1931, in Glasgow, Scotland, dead November 14, 2005, in London, was a writer and one of the founders of The Process Church of the Final Judgment. MacClean grew up under poor conditions with a single mother who often left her daughter with relatives. In the early 1960s, she moved to the United States where she lived an immersive life with the boxer Sugar Ray Robinson. After one year, she returned to the UK and London, working as call girl and joining the Church of Scientology. Among Scientologists, she met Robert Moor, later renamed by MacClean as Robert DeGrimston. They married in 1964, created their own version of auditing (Scientology) called Compulsion Analysis, and the next year they introduced the cult, The Process Church of The Final Judgment.
