LOS ANGELES (AP) — Comic strip artist Mort Walker, a World War II veteran who satirized the Army and tickled millions of newspaper readers with the antics of the lazy private “Beetle Bailey,” died Saturday. He was 94.

Walker died at his home in Stamford, Connecticut, said Greg Walker, his eldest son and a collaborator. His father’s advanced age was the cause of death, he said.

Walker began publishing cartoons at age 11 and was involved with more than a half-dozen comic strips in his career, including “Hi and Lois,” “Boner’s Ark” and “Sam & Silo.” But he found his greatest success drawing slacker Beetle, his hot-tempered sergeant and the rest of the gang at fictional Camp Swampy for nearly 70 years.

The character that was to become Beetle Bailey made his debut as Spider in Walker’s cartoons published by the Saturday Evening Post in the late 1940s. Walker changed Spider’s name and launched “Beetle Bailey” as a college humor strip in 1950.

At first the strip failed to attract readers and King Features Syndicate considered dropping it after just six months, Walker said in a 2000 interview with The Associated Press.

Walker attributed the success of the strip to Beetle’s indolence and reluctance to follow authority.

“Most people are sort of against authority,” he said. “Here’s Beetle always challenging authority. I think people relate to it.”

Greg Walker and his brother, Brian, intend to carry on their father’s work. Both have worked in the family business for decades.
