Eddie Collins
He began working in vaudeville in 1935 and was discovered in burlesque. He appeared in dozens of films. Eddie Collins played Dopey in Snow White and the Seven Dwarfs. Dopey is the only dwarf who does not have a beard. He is clumsy and mute, with Happy explaining that he has simply "never tried" to speak. In the movie's trailer, Walt Disney describes Dopey as "nice, but sort of silly". In the Disney film also he provided the sneezing of the chipmunk and the squirrel. -wikiepedia
