Theodore Sturgeon (1918-1985) was an American science fiction author. His most famous novel is More Than Human (1953). He sold his first story in 1938 to the McClure Syndicate, which bought much of his early (non-fantastic) work; his first genre appearance was "Ether Breather" in Astounding Science Fiction a year later. Sturgeon wrote the screenplays for the Star Trek episodes "Shore Leave" (1966) and "Amok Time." The latter is known for his invention of the pon farr, the Vulcan mating ritual, the first use of the sentence "Live long and prosper" and the first use of the Vulcan hand symbol.
