From Wikipedia, the free encyclopedia Hugh Milburn Stone (July 5, 1904 – June 12, 1980) was an American actor, best known for his role as Doc (Dr. Galen Adams) on the CBS Western series Gunsmoke. Stone was born in Burrton, Kansas, to Herbert Stone and the former Laura Belfield. There, he graduated from Burrton High School, where he was active in the drama club, played basketball, and sang in a barbershop quartet. His brother, Joe, was a writer who was the author of scripts for three episodes of Gunsmoke. In 1919, Stone debuted on stage in a Kansas tent show. He ventured into vaudeville in the late 1920s, and in 1930, he was half of the Stone and Strain song-and-dance act. His Broadway credits include Around the Corner (1936) and Jayhawker (1934). In the 1930s, Stone came to Los Angeles, California, to launch his own screen career. He was featured in the Tailspin Tommy adventure serial for Monogram Pictures. In 1940, he appeared with Marjorie Reynolds, Tristram Coffin, and I. Stanford Jolley in the comedy espionage film Chasing Trouble.
