Who voiced Elroy Jetson in the original series?

Daws Butler voiced Elroy Jetson in the original series.

Butler was one of Hanna-Barbera’s most versatile voice performers, and his work on “The Jetsons” extended beyond Elroy. In the original 1962–63 episodes, he also voiced characters including Henry Orbit and Cogswell, while other principal performers supplied the voices of George, Jane, Judy, Astro, Rosie, and Mr. Spacely.

Elroy is the younger child in the Jetson family, a highly intelligent boy who studies space-related subjects at Little Dipper School. Butler gave him a youthful voice that fit the character’s scientific interests and energetic personality. The role is sometimes confused with Don Messick, who voiced Astro, or Mel Blanc, who voiced Cosmo Spacely.

Butler continued voicing Elroy in several later Jetsons productions, including “The Jetsons Meet the Flintstones” and “Rockin’ with Judy Jetson.” He died in 1988 before recording for “Jetsons: The Movie,” so Patric Zimmerman performed Elroy in that feature. Later appearances used additional actors, but Butler remains the original television voice.
