Her first voice acting role was notably Oswald the Lucky Rabbit, in what would be his final short under Walter Lantz's The Egg Cracker Suite. However, some of her most famous voice roles were the titular character Rocky, Natasha Fatale, and Sherman in The Rocky and Bullwinkle Show, as well as Granny, Witch Hazel, and Miss Prissy in Looney Tunes, and related shows among others.
She had also done voice work on several Disney productions that are listed below.
Although she did extended work at Disney, she later stated one of her greatest regrets in life was never having met Walt Disney himself.
