Which of these professions was not exercised by Chuck Jones?

Charles Martin Jones (September 21, 1912 – February 22, 2002) was an American animator, voice actor, and painter, best known for his work with Warner Bros. Cartoons on the "Looney Tunes" and "Merrie Melodies" series of shorts. He wrote, produced, and/or directed many classic Animated Cartoon shorts starring Bugs Bunny, Daffy Duck, Wile E. Coyote and the Road Runner, Pepé Le Pew, and Porky Pig, among others.

Jones started his career in 1933 alongside Tex Avery, Friz Freleng, Bob Clampett, and Robert McKimson at the Leon Schlesinger Production's Termite Terrace studio, where they created and developed the Looney Tunes characters. During the Second World War, Jones directed many of the "Private Snafu" (1943-1946) shorts which were shown to members of the United States military. After his career at Warner Bros. ended in 1962, Jones started "Sib Tower 12 Productions" and began producing cartoons for Metro-Goldwyn-Mayer, including a new series of "Tom and Jerry" shorts (1963-1967) as well as the television adaptations of "Dr. Seuss' How the Grinch Stole Christmas!" (1966) and "Horton Hears a Who!" (1970). He later started his own studio, "Chuck Jones Enterprises", where he directed and produced the film adaptation of Norton Juster's "The Phantom Tollbooth" (1970).
