(written from a Production point of view)
George Henry Merhoff, Jr. (22 September 1915 – September 1972; age 56), usually credited as George H. Merhoff, was a gaffer who worked on every regular episode of Star Trek: The Original Series, from "The Corbomite Maneuver" through "Turnabout Intruder", firstly in the employ of Desilu Studios and subsequently in that of Paramount Pictures, after the acquisition of the former by the latter. While The Original Series was his primary assignment in this period of time, he occasionally stepped in to perform similar duties for Star Trek's twin sibling franchise Mission: Impossible, which was concurrently in production on the Desilu Lot.
Merhoff has written an one-page article on his experiences on the Star Trek sound-stages, titled "Beaming Up: Star Trek gaffer", that was published in June 1969 in the 12th and final issue of the Inside Star Trek fanzine.
Little is publicly known about Merhoff's life and career, but his contributions to Alfred Hitchcock's classic thriller Psycho (1960, uncredited) is known, as are his contributions to The Cabinet of Caligari (1962 as chief set electrician) with Brother John (1971) as his last recorded motion picture credit. He was son to George Merhoff, following in his footsteps as his father was also employed by the motion picture industry in the same capacity. Like his father though, Merhoff worked in near anonymity, as it was not commonplace in Hollywood of that era to officially credit studio staffers for the productions they had worked on.
