Born in Brooklyn, New York, Edwing began drawing at age nine. He started making the rounds with his cartoons after leaving the Navy in 1958, receiving $5 for his first sale in 1960. His 49-year tenure with "Mad" spanned six decades, beginning with his first two gag cartoons for the magazine: an installment of the recurring "Scenes We'd Like to See" feature and a sequence called "Nuclear Jitters," both from "Mad" #70 (April 1962). His last piece appeared in the 515th issue in 2012.
