Known most famously for playing beloved chief engineer Montgomery Scott on the classic science fiction series, "Star Trek" (NBC, 1966-69), actor James Doohan became a pop-culture icon to generations of adoring fans. His professional acting career began with prolific work in radio and television, on series such as "The Twilight Zone" (CBS, 1959-1964) and "The Virginian" (NBC, 1962-1971) prior to landing his career-making role on Gene Roddenberry's "Western set in space." As monumental as the part was, Doohan was unfortunately typecast as the tough-under-pressure Scotsman who managed to repeatedly save the U.S.S. Enterprise from danger at the very last second, while declaring in great, often flustered detail how he was going about saving it. As luck would have it, by the time he had accepted his professional lot in life, the franchise was brought back to life, bigger than ever, with the release of "Star Trek: The Motion Picture" (1979), spawning five successful sequels, in all of which Doohan made appearances. Although he found sporadic work outside the "Trek" universe, Doohan good-naturedly gave back to the loyal community of fans who for years flocked to see him and the other members of the Enterprise crew at various conventions, before passing away in 2005, the second lead to do so after the 1999 death of DeForest Kelley. A mixed blessing throughout his life to be sure, Doohan's portrayal of the beloved and beleaguered "Scotty" granted him an enduring legacy very few actors would ever have the good fortune to attain.
