If there was one actor who brought the most humanity to Star Trek, it had to be the late DeForest Kelley as Dr. Leonard 'Bones' McCoy. Born in 1920, he had built a career playing TV bad guys, usually in Westerns, which is what made it so surprising when Roddenberry cast him as The Enterprise's chief medical officer and Kirk’s conscience. After Star Trek finished its run, Kelley took on a couple of roles, but pretty much retired except for conventions, the first six big screen Star Trek adventures and a guest spot on the premiere episode of The Next Generation. He died on June 11, 1999.
