Dr. Suess
Dr. Suess, better known to friends and family as Theodore "Ted" Geisel, began his career as a member of the military. Though he would later become one of the most famous children's book authors who ever lived, he initially volunteered with the U.S Army during his rise to stardom. While overseas, he wrote satirical cartoons about Adolf Hitler and Charles Lindbergh for troops.
Bob Barker
Bob Barker's hit show, The Price is Right, gave him a lifetime of fame. Before that life though, he was a military man. Barker enlisted in the U.S Navy as a fighter pilot. Over 18 months, he was commissioned to 8 different wartime locations but was not ever assigned to a seagoing squadron due to the war ending before the opportunity arose. From there, he started a broadcasting career.
