(written from a Production point of view)
Character actor Ken Lynch (15 July 1910 – 13 February 1990; age 79) played engineer Vanderberg in the original series episode "The Devil in the Dark". However, this Star Trek role was only one of some 200 other television appearances.
He is perhaps best known for his role as Police Sergeant Grover on the TV series McCloud from 1972 through 1977. TOS/TNG guest actress Diana Muldaur was also a regular cast member on this series. Lynch was also a part of the extensive cast of the 1983 mini-series The Winds of War, which also included Lawrence Pressman, George Murdock, Peter Brocco, Michael Ensign, and Davis Roberts.
He has also made appearances in several feature films. These include such classics as the Robert Wise-directed Run Silent, Run Deep (1958), Pork Chop Hill (1959, with Paul Comi, Bert Remsen and Clarence Williams III), the 1959 adaptation of Anatomy of a Murder, Alfred Hitchcock's North by Northwest (1959, with Stanley Adams and Lawrence Dobkin), The Dark at the Top of the Stairs (1960, with Frank Overton and Paul Comi), Seven Ways from Sundown (1960, with Kenneth Tobey), Portrait of a Mobster (1961, with Leslie Parrish), Days of Wine and Roses (1962), Dead Ringer (1964, with Bert Remsen), Mister Buddwing (1966, with Jean Simmons and Nichelle Nichols), Tora! Tora! Tora! (1970, with William Schallert), and Willie Dynamite (1974, with George Murdock). One of his last roles was a guest star spot in an episode of Galactica 1980, entitled "The Night the Cylons Landed", along with Peter Mark Richman.
