Janet Waldo, the prolific voice actress best known for her role as The Jetsons’ eldest daughter Judy, has died, her daughter confirms to ABC News. Waldo was 96.

In addition to her work as the animated teen of the future, Waldo voiced a number of Hanna-Barbera cartoon characters, ranging from Penelope Pitstop to Josie and the Pussycats‘ Josie. Her last credited voice work came in 2000, when she reprised Pitstop in a Wacky Races video game.

Waldo, who passed away on Sunday morning, was diagnosed with a benign but inoperable brain tumor five years ago, says daughter Lucy Lee.

Born in Washington in 1920, Waldo began her career with an uncredited role in the 1938 film Cocoanut Grove, going on to do steady work in radio. In 1952, she appeared in an episode of I Love Lucy and went on to make television appearances on programs like The Andy Griffith Show, Get Smart, and Petticoat Junction before transitioning to animation. The Jetsons ran from 1962-1987.
