Actor. He is best remembered for playing the flamboyant and hapless criminal 'Harry Mudd' in two episodes of the NBC television science fiction series "Star Trek: The Original Series", that ran from 1966 until 1969 and one episode of "Star Trek: The Animated Series", that ran from 1973 until 1974. He was the only actor, other than those who played Enterprise crew members, to play the same character in multiple episodes of "Star Trek: The Original Series". He was born Roger Charles Carmel and after appearing on stage, he frequently guest starred on television shows during the 1960s and early 1970s, including "The Dick Van Dyke Show" (as accountant 'Doug Wesley'), "Batman" (as 'Colonel Gumm'), "Route 66", "The Patty Duke Show", "I Spy", "The Everglades", "Hogan's Heroes", "Car 54", "Banacek", "The Man from U.N.C.L.E.", "The Munsters", "Voyage to the Bottom of the Sea", and "Hawaii Five-O". In 1967 he was cast as Kay Ballard's husband 'Roger Buell' in the NBC television sitcom "The Mothers in Law" but the show was terminated after one season. He was a regular contestant on "Stump the Stars" from 1968 until 1970 and continued to appear regularly on sitcoms, mostly in ethnic roles, including appearances on "All in The Family," "Chico and The Man," and "Three's Company." He also appeared in Jerry Lewis's comeback 1981 film flop, "Hardly Working." During this time, he was cast as a regular on the television show "Fitz and Bones", but it was canceled due to poor ratings after only one month. Afterwards, he did voice-over work for children's cartoons, including 'Cyclonus' in "The Transformers." His last triumph as an actor was in commercials, where he was a huge hit in advertising playing 'Senor Naugles', a faux-Mexican "Colonel Sanders" clone, for the West Coast region Mexican fast food chain Naugles. The commercials were a success, and the chain began expanding rapidly but he then died suddenly at the age of 54. While there were rumors that he committed suicide, the official cause of death was listed as hypertrophic cardiomyopathy.
