Andy Samuel Griffith (June 1, 1926 – July 3, 2012) was an American actor, comedian, television producer, singer, and writer whose career spanned seven decades in music and television. Known for his Southern drawl, his characters with a folksy-friendly personality, as well as his gruff but friendly voice, Griffith was a Tony Award nominee for two roles. He gained prominence in the starring role in director Elia Kazan's film A Face in the Crowd (1957) and No Time for Sergeants (1958) before he became better known for his television roles, playing the lead roles of Andy Taylor in the sitcom The Andy Griffith Show (1960–1968) and Ben Matlock in the legal drama Matlock (1986–1995).
