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 a screenplay for one of the films. Heinlein edited an anthology of other writers' science fiction short stories.
