Foray, who died this week at age 99, provided the voices for many other cartoon characters during her long Hollywood career, often uncredited, according to her obituary in The New York Times.
Along with steady cartoon roles, she led efforts to launch the Annie awards for voiceover performers. She also pushed for the giving of Academy Awards for animation.
While most Rocky and Bullwinkle fans were unaware of Foray's work, she played a vital part in defining the show. Contrasting with Bullwinkle's low-pitched, slow-talking musings, Rocky's chirpy tones ranged from mock alarm to sensible insights. Rocky's voice made him the perfect straight man for Bullwinkle's star-powered comic turn.
Nastaha's sultry, Russian-inflected dialect was Forway's best work. Playing multiple roles, Nastaha in her interchanges with her partner Boris Badenov often stole the show.
Largely unknown outside of Hollywood, Foray reached millions with a mike and her array of voices.
