The science fiction writer Robert A. Heinlein (1907–1988) was productive during a writing career that spanned the last 49 years of his life; the Robert A. Heinlein bibliography includes 32 novels, 59 short stories and 16 collections published during his life. Four films, two TV series, several episodes of a radio series, at least two songs ("Hijack" by Jefferson Starship and "Cool Green Hills of Earth" on the 1970 album Ready to Ride and as the b-side of a single by Southwind) and a board game derive more or less directly from his work. He wrote the screenplay for Destination Moon (1950). Heinlein also edited an anthology of other writers' science fiction short stories.
Three non-fiction books and two poems have been published posthumously. One novel has been published posthumously and another, an unusual collaboration, was published in 2006. Four collections have been published posthumously.
Known pseudonyms include Anson MacDonald (seven times), Lyle Monroe (seven), John Riverside (one, Caleb Saunders (one), and Simon York (one).[1] All the works originally attributed to MacDonald, Saunders, Riverside and York, and many of the works originally attributed to Lyle Monroe, were later reissued in various Heinlein collections and attributed to Heinlein.
