Henri Arnold began his career as editorial and sports cartoonist for the Bridgeport Sunday Herald. During World War II, was editor of The Com-ment, the magazine of the Army Airways Communications System. He was an assistant on comic strips like 'Brenda Starr' and 'Terry and the Pirates'. After some short-lived comic features for Editors Syndicate and General Features, he settled in New York and created newspaper comics like 'Bibs 'n' Tucker' (1955-57) and 'This Man's Army' (1957-59) for the New York Sunday News and the News Syndicate.
He then became a free lance artist, working on comic books and teenage romance novels. He eventually joined the Tribune syndicate, where he became the main cartoonist of 'Jumble - That Scrambled Word Game', creating daily and Sunday puzzles in hundreds of newspapers. He also drew the 'Little Orphan Annie' strip for a short while after Harold Gray's death in 1968. He drew the 'Ching Chow' daily panel (originally created by Sidney Smith in 1927) for the New York Daily News from 1976 until 1990. It was replaced by Arnold's six-a-week comic panel 'Meet Mr. Luckey' in 1990. The artist continued the panel on the paper's sports pages until 26 December 2009, when he was 91 years old.
