Bugs Bunny is an iconic cartoon character created in 1938 by Leon Schlesinger Productions, which would later become Warner Bros. Pictures. He was voiced by Mel Blanc until 1989.
This is what Craig Chase, the original cartoonist, had to say about Bugs' development:
Bugs was not the creation of any one man; however, he rather represented the creative talents of perhaps five or six directors and many cartoon writers. In those days, the stories were often the work of a group who suggested various gags, bounced them around and finalized them in a joint story conference.
