Shortly after we learned that Alf star Minhaly "Michu" Meszaros has passed away, another 1980s TV icon has passed. Janet Waldo, who provided the voice for Judy Jetson in the hit animated series The Jetsons, has also passed away at the age of 96. The actress' death was confirmed by her daughter, Lucy Lee, who revealed that her mother passed on Sunday afternoon.

Lucy Lee confirmed to ABC News that her mother had been diagnosed with a benign yet inoperable brain tumor five years ago. Janet Waldo was born in Yakima, Washington in 1920, and she was studying at the University of Washington when she was discovered by movie star Bing Crosby, who encouraged her to try out for a talent competition which she won. She was cast in a number of small roles in Bing Crosby's films, such as Sing, You Sinners and The Star-Maker, before setting her sights on radio productions in 1943.

She became a household name by voicing the teenager in Meet Corliss Archer, and also performed in radio productions One Man's Family, The Gallant Heart and Star Playhouse. She went on to play characters Janet, Emmy Lou, Ann and others in The Adventures of Ozzie and Harriet in the 1950s, before landing the role of Judy Jetson in the 1962 series The Jetsons. While the show only lasted one 24-episode season between 1962 and 1963, it was revived in 1985, to run in syndication along with the first season of the animated series.

She also voiced a number of different characters like Mrs. Slaghoople in The Flintstones, Josie in the 1970 animated series Josie and the Pussycats and voiced Morticia Addams on the animated version of The Addams Family. Janet Waldo also voiced a number of characters on Alvin and the Chipmunks, along with Hogatha on The Smurfs and Mrs. Tobbis on an episode of King of the Hill. Her last credit was voicing Penelope Pitstop in the 2000 video game Wacky Races.

Janet Waldo also voiced Judy Jetson in Rockin' With Judy Jetson, an animated TV movie and in the 1990 animated feature film Jetsons: The Movie. We reported back in January 2015 that Warner Bros. was developing an animated Jetsons movie, after the studio scrapped their initial plans to make a live action project. We haven't heard anything about the project since then, so we're not sure how far along it is in development.
