John Marshall is an American cartoonist, best known as the artist of the Blondie comic strip since 2005. He works closely with scripter Dean Young, son of the strip's creator, Chic Young.
Born in Waverly, New York, John Marshall took an interest in cartooning at an early age. He was bored during the summer between the fourth and fifth grades and began drawing Peanuts characters on brown paper bags. When he was 14, his career as a cartoonist was jump-started by his grandmother who urged him to send cartoons to Parade. On his first try, Parade bought one. Marshall recalled, "It's tough peaking in the tenth grade." This was followed by a sale to The Saturday Evening Post.
Graduating in 1976 from Ringling School of Art and Design in Sarasota, Florida, Marshall began as an art director at a Binghamton, New York, advertising agency, eventually making the leap as a freelance illustrator, with a client list that included General Electric, IBM and Golf Digest.
In 1982, Marshall created the comic strip, Buford, distributed through Syndicated News Services, Inc. From 1994 to 2000, he worked with Mark Cullum on the King Features strip Walnut Cove. Marshall's editorial cartoons regularly appeared in the Press & Sun-Bulletin (Binghamton, New York) from 1989 to 2003. In the summer of 2002, he lettered and inked Hägar the Horrible. From February 2001 to January 2003, his daily panel, The U.S. of Play, appeared on United Features Syndicate's website. "I floundered for a couple of years," said Marshall, but he found a new direction in 2002 when he got a phone call from King Features to work on Blondie.
