L. Ron Hubbard (March 13, 1911 - January 24, 1986), better known as L. Ron Hubbard, was a prolific American author and founder of the controversial Church of Scientology. In addition to Scientological and self-help books, he wrote fiction in several genres but predominantly science fiction, business management texts, essays, and poetry.
The Church of Scientology has produced numerous biographical accounts of Hubbard's life and career, but no book. These accounts generally tend to be glowing reviews, without much critical insight. There have also been a few biographies done independent of the Church of Scientology. These independent works examine Hubbard's life from a critical viewpoint. They often contradict the biographies presented by the Church.
