The undisputed King of Cartoons is Frederick Bean Avery, aka Tex Avery. Although he and his work have been featured before in numerous Neatorama posts, none have ever told his whole story. Following are the high points of the man and his career:
1. Tex was blind in one eye, which actually helped his cartooning.
2. At Leon Schlesinger's studio (later bought by Warner Brothers) Tex gave life to existing characters like Bugs Bunny and Daffy Duck. He is famous for creating the the Exaggerated Take, an example of which is seen above.
3. At the height of his success at Schlesinger's, he left for MGM in 1941. Reports vary as to his quitting or being fired for insubordination.
4. At MGM, Tex created masterpiece after masterpiece, surpassing his work at Schlesinger's. He quit MGM in 1954, working for Walter Lantz a short time, before leaving theatrical cartoons altogether in favor of animated commercials such as Raid and the Frito Bandido.
5. Tex went full-circle late in life, returning to directing cartoons for Hanna-Barbara, his old friendly rivals at MGM, before his death in 1980.
It should be noted that Tex created the famous Bugs Bunny line 'What's Up, Doc?', claiming later that this was just something that was in the popular vernacular in his high school. My grandfather, who was about the same age as Tex and was also in Dallas, Texas, at the same time as Tex, was named Walter but carried the nickname 'Doc' all of his life. Truth is stranger than fiction.
