BTW..did you know that Hal Smith aka Otis the Town Drunk on The Andy Griffith Show was Goliath??
Dick stood 4'7" due to a glandular problem which also gave him his youthful voice. He was playing ten-year-old boys well into his seventies and was often called upon to loop (i.e., dub in the voice of) live-action child actors in movies or on TV programs.
He started in radio dramas in 1949 while attending Michigan State University. Several popular radio programs emanated from Detroit at the time and Dick wound up being heard on all of them but most notably The Lone Ranger, Challenge of the Yukon and The Green Hornet. His later cartoon credits include his being the first voice of Gumby and the first voice of Davey on the Davey & Goliath cartoon series. He was a loyal team member on the Roger Ramjet cartoon show and was heard throughout many Hanna-Barbera shows.
