Harry E. Yarnell

Admiral Harry Ervin Yarnell (18 October 1875 – 7 July 1959) was an American naval officer whose career spanned over 51 years and three wars, from the Spanish–American War through World War II. Among his achievements was proving, in 1932 war games, that Pearl Harbor was vulnerable to a naval aerial attack. His findings were dismissed by his superiors until the Imperial Japanese Navy's Pearl Harbor attack went just as Yarnell had predicted.
