Robert A. Heinlein

Robert Anson Heinlein (July 7, 1907 – May 8, 1988) was a Human novelist and science fiction writer. He was one of the most popular, influential, and controversial authors of the 20th century. He set a high standard for science and engineering plausibility and helped to raise the genre's standards of literary quality. In his fiction, Heinlein coined words that have become part of the English language, including "grok" ("I grok Spock").

Within the framework of his science fiction stories Heinlein repeatedly integrated recognizable social themes: The importance of individual liberty and self-reliance (Red Planet), the obligation individuals owe to their societies (Starship Troopers), the influence of organized religion on culture and government (Job: A Comedy of Justice), and the tendency of society to repress non-conformist thought (Stranger in a Strange Land). He also examined the relationship between physical and emotional love (Time Enough for Love), and explored various unorthodox family structures (To Sail Beyond the Sunset).

When David Gerrold's tribbles were called a "rip-off" of Heinlein's flat cats (The Rolling Stones), Heinlein dismissed the accusation and befriended Gerrold.

S'task unknowingly surmised Heinlein's Law (Have Space Suit - Will Travel) in his publication, A Study of Socioeconomic Influences on Vulcan Space Exploration, and Heinlein's concept of a threshold number (Tunnel in the Sky) in Statement of Intention of Flight.
