Joseph John Rochefort, the man whose decoding of the Japanese codebook led to the American victory at the Battle of Midway, had enemies other than the Empire of Japan. His feats at cryptanalysis were phenomenal, but not universally appreciated, particularly by the codebreakers in Washington, D.C. Naval jealousy and internal machinations would rob Joseph Rochefort of the honor that was due to him for his brilliant work in predicting where the Japanese fleet would strike after Pearl Harbor.
Rochefort, who had not gone to the Naval Academy, was an outsider from the beginning of his naval career. He was still in high school when he enlisted in the Navy in 1918 with the goal of being a naval aviator. He claimed to have been born in 1898 so that he would seem old enough for a military career, and didn't even have a high school diploma when he was commissioned as an ensign after graduating from the Navy's Steam Engineering School at Stevens Institute of Technology.
