Pinto Colvig

From The Unofficial DisneyWiki

Pinto Colvig was a "story man" at the Disney Studio, perhaps better known for his voice work. His most famous role was as the voice of Goofy; he was responsible for the famous Goofy Holler, the recording of which has been used for many different films, including Cinderella and The Hunchback of Notre Dame, as characters fall from great heights - it has become something of a wilhelm scream for Disney. He also provided the voices of Grumpy and Sleepy in Snow White and the Seven Dwarfs.
