James "Jim" W. Rugg (29 January 1919 – 13 February 2004; age 85) was an Emmy Award-nominated special effects supervisor who worked on all three seasons of Star Trek: The Original Series. He was responsible for the live production special effects, such as explosions. He most famously oversaw the iconic mechanical and wiring effects of the Enterprise main bridge, other standing sets, and special set pieces such as Nomad, Flint's M-4, and the Guardian of Forever.
During his long career in television, Rugg designed special effects for such series as Mission: Impossible, Hawaii Five-O, Barnaby Jones (starring Lee Meriwether), Cannon, and Perry Mason. He also worked on several feature films including River of No Return (1954, with Hal Baylor), Mary Poppins (1964), and Douglas Trumbull's 1972 science fiction film Silent Running, which also featured special effects and visual effects work by Jim Dow, Paul Kraus, Don Trumbull, John Dykstra, Richard Alexander, Robert Shepherd, Richard Yuricich, Bill Shourt, and Trumbull himself.
Rugg retired in 1981. He passed away at the age of 85 in 2004 of Alzheimer's disease.
