Robert Anson Heinlein was an American science fiction writer. 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 words that have become part of the English language, including "grok" and "waldo", and popularized the terms "TANSTAAFL" and space marine.
Heinlein was born on July 7, 1907 to Rex Ivar Heinlein (an accountant) and Bam Lyle Heinlein, in Butler, Missouri. He was a 6th-generation German-American: a family tradition had it that Heinleins fought in every American war starting with the War of Independence.
In 1929, Heinlein married Elinor Leah Curry of Kansas City in Los Angeles, but their marriage lasted for only about a year. His second marriage in 1932 to Leslyn MacDonald (1904–1981) lasted for 15 years.
