A.B.C. Whipple died of pneumonia Sunday in Greenwich, Connecticut at the age of 94, his son Chris Whipple told the Associated Press.

A former pentagon correspondent for Life magazine A.B.C. Whipple dies after changing the course of photojournalism with his role in getting a graphic image from World War II published.

While at Life, A.B.C. Whipple worked to persuade the military to grant the magazine the right to publish a photo of three dead soldiers on a landing beach. The photo was eventually published after being cleared by President Franklin D. Roosevelt himself.

The WWII photo getting published in Life was the beginning of the end of the enforcement of a censorship rule limiting wartime information and images coming in and out of the United States.

"I think that he felt this was a watershed in the course of the war," Chris Whipple told the AP. "I think that he felt that in his own way he had made a real contribution. I think he thought it was a special achievement and probably the most important thing he did as a journalist."

Speaking in 1986, A.B.C. Whipple said it took a lot of diplomacy to get the photo printed, according to the Epoch Times.

"It took a lot of negotiating on the part of a lot of people at Life who were trying to get that picture cleared," he said.

A.B.C. Whipple went on to become the executive editor of Time-Life Books, he dies leaving behind over a dozen books about maritime history.
