From The Unofficial DisneyWiki

Roy Atwell (May 2, 1878-February 6, 1962) (age 84) was a radio comedian, broadway performer and composer. He was chosen to voice Doc, the pompous, self-appointed leader of the seven dwarfs in Snow White and the Seven Dwarfs, because he had already incorporated stuttering and wordplay into his radio performances.
