Otis Campbell, the local sot on the Andy Griffith Show, and charismatic cartoon pooch Goofy were among the characters portrayed by Hal Smith during his career as an actor and voice-over artist respectively. A Midwesterner, Smith was also associated with the voices on various Hanna-Barbera cartoon series created in the '70s, some of them quite obnoxious -- the voices as well as the cartoons. Smith can be heard on children's recordings created for Walt Disney including adaptations of both the Snow White and Winnie the Pooh epistles. On Disney's Duck Tales, Smith perfected roles such as Flintheart Glomgold, rival to the greedy Scrooge McDuck. He also portrayed pea-brained scientist Gyro Gearloose. Beginning in 1987 Smith acted on the evangelical radio drama Adventures in Odyssey. He died of a heart attack in the first half of the '90s.
