Animated the opening title sequences for Hanna-Barbera's first two
prime-time series- "The Flintstones" (first season titles, with the
"Rise and Shine" theme) and "Top Cat". He also animated the entire
first-produced episode of "The Flintstones"- "The Swimming Pool" (aired
as episode 3) as well as the pre-series "Flagstones" pilot. He was
probably the studio's most prolific animator in its heyday of the late
fifties and sixties.
