Lafayette Ronald Hubbard (March 13, 1911 – January 24, 1986), better known as L. Ron Hubbard (/ɛl rɒn ˈhʌˌbərd/, ELL-ron-HUB-ərd) and often referred to by his initials, LRH, was an American author and the founder of the Church of Scientology. In 2014, Hubbard was cited by the Smithsonian magazine as one of the 100 most significant Americans of all time, as one of the eleven religious figures on that list. After establishing a career as a writer, becoming best known for his science fiction and fantasy stories, he developed a system called Dianetics which was first expounded in book form in May 1950. He subsequently developed his ideas into a wide-ranging set of doctrines and practices as part of a new religious movement that he called Scientology. His writings became the guiding texts for the Church of Scientology and a number of affiliated organizations that address such diverse topics as business administration, literacy and drug rehabilitation. The Church's dissemination of these materials led to Hubbard being listed by the Guinness Book of World Records as the most translated and published author in the world.
