Christine Cavanaugh, who provided the voice to such beloved cartoon characters as Dexter from Dexter’s Laboratory and Chuckie from Rugrats, died on Dec. 22, reports TMZ. She was 51.

Having also voiced characters in The Powerpuff Girls, Recess, 101 Dalmations: The Series, and Sonic the Hedgehog, Cavanaugh, who retired from voiceover work in 2001, also made live-action appearances on Cheers, The X-Files, Salute Your Shorts and more.

Similarly familiar as the voice of the titular porcine role in the 1995 movie Babe, Cavanaugh won an Annie Award in 2000 for outstanding individual achievement for voice acting by a female performer in an animated television production for her work as Dexter on the hour-long special Dexter’s Laboratory: Ego Trip.

Though she had no biological children of her own, Cavanaugh was the godmother to the child of her close childhood friend, according to the Los Angeles Times.
