Addison Beecher Colvin (A.B.C.) Whipple, author and journalist, has died.

The Associated Press reports that Whipple died on Sunday, March 17 from Pneumonia.

Whipple is, perhaps, best known for his work as a Pentagon correspondent for Life magazine during World War II. He was instrumental in pressuring the U.S. military to allow the publication of a photograph of dead U.S. soldiers. Whipple pressured war censors for the clearance, eventually getting the attention of Franklin D. Roosevelt, who allowed the publication of the image. The AP states that the event ended the censorship rule against publishing photos of dead soldiers.

After the war, Whipple continued to report for Life and began writing books, most of them about sailing and seafaring. Throughout his career, Whipple authored more than 20 workss, such as Vintage Nantucket, The Whalers, and The Mysterious voyage of Captain Kidd.

Whipple went on to become an executive editor at Time-Life Books.
