Lucille Theresa Bliss was an American actress and voice artist.

A New York City native, Bliss lent her voice to numerous television characters, including the title character of the very first made-for-television cartoon, Crusader Rabbit, Smurfette on the popular 1980s cartoon The Smurfs and Ms. Bitters on the Nickelodeon animated series Invader ZIM. In addition to her television roles, she was known for her work as a voice actor in feature films.

Life and career:
Bliss' first voice work was the role of the wicked stepsister Anastasia Tremaine in Walt Disney's 1950 feature film Cinderella, for which she was honored 50 years later by the Young Artist Foundation with its Former Child Star "Lifetime Achievement" Award in March 2000.

From 1950–57, Bliss was "Auntie Lou" on San Francisco, California's KRON-TV's The Happy Birthday To You Show, also known as Birthday Party Show, which had guests from adults, to children, to animals. At the same time, she did voices for Hanna-Barbera while they were working for MGM – as Tuffy in Robin Hoodwinked, as Leprechaun in Droopy Leprechaun and later was Hugo on an episode of The Flintstones. She was also the narrator on three stories from the Disney album "Peter Cottontail and Other Funny Bunnies": "Story of Thumper", :Story of the White Rabbit", and "Story of Grandpa Bunny". Bliss was also a voice-over performer for Airborne radio spots in 2004.
Death:
Bliss died from natural causes on November 8, 2012 at the age of 96. She is buried at Hollywood Forever Cemetery.
