When Tex Avery arrives at the M.G.M.'s animation department in 1942, he has already provided the realization (the supervision as Hollywood said) of more than sixty cartoons for Warner Bros.

Frederic Bean Avery was born in Texas on February 26, 1908. From 1928, he learns the basis in the Universal's animation department whose was directed by Walter Lantz.

In 1935, Avery joined Warner and a group of psychopaths whose hampered Leon Schlesinger, who had in charge the production of the series Merries Melodies (colors) and Looney Tunes (in black and white): Chuck Jones, Bob Clampett and Bob Cannon. With Virgil Ross and Sid Sutherland, they form the Termit Terrace's famous team, who gives birth to Porky Pig, Daffy Duck and, of course, Bugs Bunny.

"When Avery arrived at Warner's studio, he was very impatient to use insane and sexy gags" said Bob Clampett. The humour of Avery is somewhat attached during its first Warner's years. But, gradually, a extremely personal style begin to impregnate his cartoons, without reaching for as much the nodes of M.G.M.'s period. Afterwards, Tex Avery does not hesitate to revisit characters, topics or gags.

After a conflict of interest with Schlesinger, Frederic Avery leaves Warner in 1942 and joined the animation department of the M.G.M. to become Tex Avery.
