William Elder (born Wolf William Eisenberg; September 22, 1921 – May 15, 2008) was an American illustrator and comic book artist who worked in numerous areas of commercial art but is best known for a frantically funny cartoon style that helped launch Harvey Kurtzman's Mad comic book in 1952. Playboy publisher Hugh Hefner said, "He was a zany, and a lovable one." Longtime Mad writer-cartoonist Al Jaffee called Elder "Absolutely brilliant... he was the star from the beginning. He had a feel for the kind of satire that eventually spread everywhere."
