Who was Mary Sue Hubbard?

Mary Sue Hubbard, née Whipp; June 17, 1931 – November 25, 2002 was the third wife of L. Ron Hubbard, from 1952 until his death in 1986. She was a leading figure in Scientology for much of her life. The Hubbards had four children; Diana, Quentin, Suzette, and Arthur.

She became involved in Hubbard's Dianetics in 1952, while still a student at the University of Texas at Austin, becoming a Dianetics auditor. She soon became involved in a relationship with Hubbard and married him in March 1952. She accompanied her husband to Phoenix, Arizona, where they established the Hubbard Association of Scientologists – the forerunner of the Church of Scientology, which was itself founded in 1953. She was credited with helping to coin the word "Scientology". She played a leading role in the management of the Church of Scientology, rising to become the head of the Church's Guardian's Office. In August 1978, she was indicted by the United States government on charges of conspiracy relating to illegal covert operations mounted by the Guardian's Office against government agencies. She was convicted in December 1979 and was sentenced to five years' imprisonment and the payment of a $10,000 fine.
