Probably not, but we guarantee you, you've heard his voice.
His name is Pinto Colvig. He was active in the animation industry from its beginnings and wound up providing the voice for Walt Disney's Goofy. He also voiced Practical Pig (of Disney's :3 Little Pigs") and 2 of the 7 Dwarfs (Sleepy & Grumpy) as well as providing the barks for Pluto in the early Mickey Mouse cartoons.
In 1946, Capitol Records launched a series of albums aimed at children featuring a circus clown they called Bozo. Once again, Colvig was the man behind Bozo's voice for over a decade.
He passed away in 1967 at the age of 75.
