He was a voice actor. In the late 1920's he was hired to do a show called, "The Merrymakers", at a Los Angeles radio station. He did commercials for the Adorh Milk Company as "Whistling Clarence, the Adorh Bird Man". He heard that animal cartoons were being done by The Walt Disney Studios, stopped by and got an audition. After doing his impression of a family of ducks, Walt decided to use him in a cartoon called, "The Wise Little Hen". Mr. Nash was the voice of Donald Duck for over 50 years. He said, "Actually, I wanted to be a doctor, but instead I became the biggest quack in the World." His voice was used in over 150 cartoon shorts and films. He said the hardest challenge was doing the voice of Donald Duck in foreign languages. Words were written in his script phonetically. He said that doing Donald in German was the hardest. He was also the voice of Daisy Duck in her early appearances and also was the voice for Donald's nephews, Huey, Dewy and Louie. He also did the voice of a bullfrog in "Bambi"; dogs in "101 Dalmations"; and birds in the Enchanted Tiki Room at Disneyland. He entertained at school assemblies, hospitals and orphanages with a fiberglass Donald Duck ventriloquist doll (shown in photograph). He supplied Donald's voice for the Oscar-nominated featurette, "Mickey's Christmas Carol" in 1983. Next year he appeared on the Academy 6 Awards CBS television special, "Donald Duck's 50th Birthday" and at special Disney theme park celebrations. At the White House, President Ronald Reagan gave him a plaque commemorating his unique place in American family entertainment.
