Question: Are Archibald MacLeish and L. Ron Hubbard both writers ?
Context: J.B. is a 1958 play written in free verse by American playwright and poet Archibald MacLeish and is a modern retelling of the story of the biblical figure Job – hence the title: J.B./Job.  The play went through several incarnations before it was finally published.  MacLeish began the work in 1953 as a one-act production but within three years had expanded it to a full three-act manuscript. Margaret Louise "Polly" Grubb (September 22, 1907 – November 17, 1963) was the first wife of pulp fiction author and Scientology founder L. Ron Hubbard, to whom she was married between 1933 and 1947.  She was the mother of Hubbard's first son, L. Ron Hubbard, Jr. and his first daughter, Katherine May "Kay" Hubbard. Lafayette Ronald Hubbard (March 13, 1911 – January 24, 1986), better known as L. Ron Hubbard ( ) and often referred to by his initials, LRH, was an American author and the founder of the Church of Scientology.  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.  The Guinness World Record for the most audio books published for one author is also held by Hubbard.  In 2014, Hubbard was cited by "Smithsonian" magazine as one of the 100 most significant Americans of all time, as one of the eleven religious figures on that list. Archibald MacLeish (May 7, 1892 – April 20, 1982) was an American poet and writer who was associated with the Modernist school of poetry.  MacLeish studied English at Yale University and law at Harvard University.  He enlisted in and saw action during World War One, and lived in Paris in the 1920s.  On returning to the US, he contributed to Henry Luce's magazine "Fortune" from 1929 to 1938.  For five years MacLeish was Librarian of Congress, a post he accepted at the urging of President Franklin D. Roosevelt.  From 1949 to 1962, MacLeish was Boylston Professor of Rhetoric and Oratory at Harvard University.  MacLeish was awarded three Pulitzer Prizes for his work. Scientology in the United Kingdom is practised mainly within the Church of Scientology and its related groups which go under names including "Hubbard Academy of Personal Independence" and "Dianetics and Scientology Life Improvement Centre".  The national headquarters, and former global headquarters, is Saint Hill Manor at East Grinstead, which for seven years was the home of L. Ron Hubbard, the pulp fiction author who created Scientology.  Church-connected groups promoting aspects of L. Ron Hubbard's teaching, including Narconon and CCHR, have also been active in the UK, in some cases with charitable status.  There have also been groups practising Scientology independently of the Church. Brain-Washing: A Synthesis of the Russian Textbook on Psychopolitics, sometimes referred to as The Brainwashing Manual, is a book published by the Church of Scientology in 1955.  It purports to be a condensation of the work of Lavrentiy Beria, the Soviet secret police chief.  The book states Kenneth Goff as author.  Its true authorship is not clear, the three common hypotheses being: Scientology founder L Ron Hubbard, Kenneth Goff (alias Oliver Kenneth Goff), or both L Ron Hubbard and Kenneth Goff based on an acquired US agency report.  The third hypothesis is questionable as there is not proof that the two men ever knew each other.  Claims that L Ron Hubbard was the author are also dubious as the only source of this claim is his estranged son, L Ron Hubbard Jr., who made it his life work trying to intentionally discredit his father in every possible way, and in addition to withdrawing all his accusations before his death, has been discredited in courts of law. Bare-faced Messiah: The True Story of L. Ron Hubbard is a posthumous biography of Scientology founder L. Ron Hubbard by British journalist Russell Miller.  First published in the United Kingdom on 26 October 1987, the book takes a critical perspective, challenging the Church of Scientology's account of Hubbard's life and work.  It quotes extensively from official documents acquired using the Freedom of Information Act and from Hubbard's personal papers, which were obtained via a defector from the Church.  It was also published in Australia, Canada and the United States. Roderick MacLeish (January 15, 1926 – July 1, 2006) was an American journalist and writer.  Born in Bryn Mawr, Pennsylvania, he grew up in the Chicago suburbs and graduated from the University of Chicago.  MacLeish was news director for WBZ radio in Boston in the early 1950s, then helped start the London and Washington, DC, bureaus of Westinghouse Broadcasting, where he was a chief commentator.  He later was a commentator for CBS News, National Public Radio, and "The Christian Science Monitor".  His published books include both nonfiction and fiction.  MacLeish was the nephew of poet Archibald MacLeish.  He died in Washington, DC, at the age of 80. L. Ron Hubbard, Messiah or Madman? , is a posthumous biography of Scientology founder L. Ron Hubbard written by Bent Corydon, which makes extensive use of interviews he conducted with Hubbard's son Ronald DeWolf.  Though originally published in 1987 by Lyle Stuart Inc., the book was re-issued in a paperback edition on July 25, 1992 and a hardcover edition in October 1995, both by publisher Barricade Books.  The 1995 edition also featured Brian Ambry as principal researcher.  The first edition of the book listed DeWolf as coauthor. A Piece of Blue Sky: Scientology, Dianetics and L. Ron Hubbard Exposed is a 1990 book about L. Ron Hubbard and the development of Dianetics and the Church of Scientology by British former Scientologist Jon Atack.  The title originates from a quote of Hubbard's from 1950, when he was reported as saying that he wanted to sell potential church members a "piece of blue sky."
