American screenwriter and novelist (1917–2008) who contributed to three episodes of the original Star Trek: The Galileo Seven, Let That Be Your Last Battlefield and The Cloud Minders.
Oliver Crawford was an American screenwriter whose career was interrupted by the Hollywood blacklist of the 1950s and who later became a prolific television writer.
For Star Trek he devised the story of The Galileo Seven, the first-season episode that strands Spock in command of a crashed shuttlecraft, and shared its teleplay credit with S. Bar-David, the pen name of Shimon Wincelberg.
In the third season he wrote the teleplay of Let That Be Your Last Battlefield from a story credited to Lee Cronin, a pseudonym of Gene L. Coon, and he shared the story credit for The Cloud Minders with David Gerrold, with Margaret Armen writing that teleplay.
