Some of the most popular names that crop up have been Mel Blanc and Daws Butler - both who have had legacies larger than Russia, both who served their various companies well, and both who have worked together long-term, notably when Hanna-Barbera Productions first opened up shop.
Although he made his name first at MGM and then later Hanna-Barbera, Daws Butler also lent his voice to many commercials and animation shorts. What I also respect about Daws was the fact he shared his talents and skills with the world, training young people of the time the fine art of voice-acting, making them the stars they are today - just ask Nancy Cartwright and Joe Bevilacqua =)
Without Daws, we'd probably never have the likes of Huckleberry Hound, Yogi Bear nor Quick Draw McGraw to recall and enjoy countless times over...that is if you happen to be as big a HB fan aside others.
If you'd like to know more about Daws Butler - or Hanna-Barbera in general - be sure to check out Yowp's Early Hanna-Barbera Cartoons blog with plenty of interviews, newspaper cuttings and in-depth episode reviews!
Meantime, here's some other vids featuring the vocal talents of Daws himself.
This cute short is one of Sesame Street's often-recalled segments, featuring an Elroy Jetson-type narrator. Rather like the odd concept of a photographic train yard, which helps the lil' J stand out - even odder when one finds an A4 Pacific in an American Railroad yard!!
Daws was also fondly remembered as the voice of Cap'n Crunch, mascot for Cap'n Crunch cereal. The animation, I believe, was produced by Jay Ward Productions:
This last one's my personal favourite - next to being a voice actor, Daws was also a nifty writer, collaborating and voicing this set of Bosco Chocolate Sauce adverts with veteran animator/musician/cartoonist Bud Luckey. Rumour has it that the third, larger bunny here might be voiced by Thurl Ravenscroft, but please feel free to correct me:
