Dalton's first commercial animation work was in 1930 at the ill-fated
Romer Grey Studios. He later worked on an animated short version of
The Wizard of Oz that was produced by
Ted Eshbaugh's independent animation studio in 1933. Afterwards, Dalton left to work at
Leon Schlesinger Productions, with his first project being 1934's
Viva Buddy. All together, Dalton worked on 33 Warner Bros. cartoons as part of their animation department. In 1937, he animated on the
Bob Clampett directed segment for ''
When's Your Birthday?''. Dalton later admitted feeling aggrieved about the fact that while he was meant to be nominally in charge of Freleng's former unit, he tended to be overshadowed by the presence of the more experienced Hardaway. Dalton's major contribution to the legacy of Warner Bros. animation was having co-directed
Hare-um Scare-um in 1939 with Hardaway. The short featured a gray and white
rabbit that served as the prototype for
Bugs Bunny. Dalton directed or co-directed a total of 17 Warner Bros. cartoons from 1938 through 1940. He spent the rest of his years at Warner Bros. doing strictly animation work before leaving the studio in 1947. Dalton's last project was
The Goofy Gophers (1947), which was the first cartoon to feature those characters. He also did some uncredited animation in the
Daffy Duck cartoon called
Mexican Joyride (1947). ==References==
