William D. Leahy

William D. Leahy (1875-1959) was an American Fleet Admiral and Chief of Staff to Presidents Franklin D. Roosevelt and Harry S. Truman during World War II, serving as the highest-ranking U.S. naval officer. His name appears in U.S. Navy historical records on U-2 aircraft testing and UFOs (now UAP), listed alongside other top admirals like Nimitz and King in discussions of high-altitude flights that spurred UFO reports investigated by Project Blue Book in the 1950s. No direct achievements, publications, or testimony by Leahy in UAP research are documented; his association is contextual via Navy leadership during the era's phenomena.
