Robert Anson Heinlein July 7, 1907 – May 8, 1988) was an American science fiction writer. Often called the "dean of science fiction writers", he was an influential and controversial author of the genre in his time.

Heinlein was named the first Science Fiction Writers Grand Master in 1974. He won Hugo Awards for four of his novels; in addition, fifty years after publication, three of his works were awarded "Retro Hugos"—awards given retrospectively for works that were published before the Hugo Awards came into existence. In his fiction, Heinlein coined terms that have become part of the English language, including "grok" and "waldo", and speculative fiction, as well as popularizing the terms like "TANSTAAFL", "pay it forward", and space marine. He also described a modern version of a waterbed in his novel The Door Into Summer, though he never patented or built one. In the first chapter of the novel "Space Cadet" he anticipated the cell phone, 35 years before the technology was invented by Motorola. Several of Heinlein's works have been adapted for film and television.
