June Foray has passed away. If her name isn't familiar to you, her voice will be.
She was the voice of dozens of cartoon characters including Rocky the Flying Squirrel and Natasha Fatale from the Rocky and Bullwinkle Show, Witch Hazel, Granny from the Tweety and Sylvester cartoons, Nell Fenwick from Dudley Do-Right, and many more.
She was also the voice of Talkie Tina in the Twilight Zone episode: "Living Doll"
