George Lowe, a longtime voice actor who lent his talents to shows like “American Dad!” and “Space Ghost Coast to Coast,” died Sunday, a representative confirmed. He was 67.

A cause of death was not shared.

Born in Florida in 1958, Lowe got his start at WWJB, a local radio station when he was just 15. Honing his swooping vocal style and ability to bring life to characters without ever being seen, Lowe appeared sporadically on the Cartoon Network and TBWS throughout the 1980s and early ’90s, according to Deadline, before landing his big break on “Space Ghost Coast to Coast” in 1994.

Starring as the Hanna-Barbera character Space Ghost, the host of a late-night comedy show parody, Lowe interviewed real-life celebrity guests like “The Nanny” lead Fran Drescher and “Taking Heads” frontman David Byrne. The program ran from 1994 to 1999 and was revived in 2001 for another three years by Adult Swim, Cartoon Network’s programming block aimed at an older audience, and GameTap, TBS’ online video game service, from 2006 to 2008.

Lowe’s voice also appeared in “Robot Chicken” and “Aqua Teen Hunger Force,” both popular Adult Swim programs in their own right. He also voiced Cyrus Mooney on “American Dad!”

In a post to Facebook, longtime friend and Florida-based radio DJ “Marvelous Marvin” Boone mourned Lowe’s loss.

“I’m beyond devastated. My Zobanian brother and best friend for over 40 years, George Lowe, has passed away after a long illness,” Boone wrote. “A part of me had also died. He was a supremely talented artist and voice actor. A true warm hearted genius. Funniest man on earth too. I’ve stolen jokes from him for decades. He stole some of mine. He was also the voice of Space Ghost and so much more.”
