Everybody probably knows that Scotty is Kirk’s right hand engineer, and the Starfleet captain would have been up the creek many times if it were not for the capable Chief Engineer.

James Doohan
James Montgomery “Jimmy” Doohan ( /ˈduːən/ doo-ən; March 3, 1920 – July 20, 2005) was a Canadian character and voice actor best known for his role as Montgomery “Scotty” Scott in the television and film series Star Trek. Doohan’s characterization of the Scottish Chief Engineer of the Starship Enterprise was one of the most recognizable elements in the Star Trek franchise, for which he also made several contributions behind the scenes. Many of the characterizations, mannerisms, and expressions that he established for Scotty and other Star Trek characters have become entrenched in popular culture
