The transporter chief of the USS Enterprise in 2254, who beamed Captain Pike's landing party to Talos IV and was at the controls when the Talosians snatched only the women from the rescue team.
Pitcairn is the transporter chief of the USS Enterprise under Captain Christopher Pike, appearing in the first pilot, The Cage, and in the reused scenes of The Menagerie.
A gruff, older technician in a work smock, he operates the console with an assistant when Pike's party first beams down to the surface of Talos IV in answer to the Columbia distress call.
Later, when Number One leads an armed team intended to materialise inside the Talosian underground complex, Pitcairn energises the transporter only for the Talosians to interfere. Number One and Yeoman Colt vanish from the platform while the men are left standing, and he can only report in alarm that the women alone have gone. He was played by Clegg Hoyt.
