Uh... you know he was a Canadian right?
James Montgomery Doohan (/ˈduːən/; March 3, 1920 – July 20, 2005) was a Canadian actor and author, 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, and inspired many fans to pursue careers in engineering and other technical fields.[1] He also made contributions behind the scenes, such as the initial development of the Klingon and Vulcan languages. Prior to his acting career, Doohan served in the 14th Field Artillery Regiment of the 3rd Canadian Infantry Division.
