Robert Anson Heinlein was educated at the University of Missouri and the U.S. Naval Academy. After serving as a naval officer for five years, he retired for health reasons and began publishing SF in 1939. Considered the dean of American SF writers, Heinlein was loved and emulated during the half century that he wrote SF. He wrote dozens of novels and short stories, including Double Star, Stranger in a Strange Land, and The Moon is a Harsh Mistress, all of which won Hugo Awards. Heinlein was the recipient of the First Grand Master Nebula in 1975, and he was the guest of honor at three World SF Conventions: in 1941, 1961, and 1976. He has repeatedly been voted "best all-time author" in readers' polls. Robert A. Heinlein passed away in 1988.
