1886–1950
A pioneering American air commander, he helped shape military aviation from the era of the Wright brothers to the global air campaigns of World War II. Best known as “Hap” Arnold, he became the only officer to hold five-star rank in both the U.S. Army and the U.S. Air Force.

by Henry Harley Arnold
Graduating from West Point in 1907, he began in the infantry before moving into military aviation at a time when flight was still new and experimental. He learned to fly from the Wright brothers and became one of the U.S. Army’s early airmen, building a career alongside the growth of American air power.
During World War II, he served as commanding general of the U.S. Army Air Forces and was a key architect of the massive expansion of American air strategy, training, and technology. His career linked the fragile aircraft of the early 1900s with the powerful bomber fleets and advanced research programs of the 1940s.
Arnold is often remembered as one of the central figures in the rise of the modern Air Force. In 1949, he was named the first General of the Air Force, a rare distinction that reflected both his wartime leadership and his lasting influence on U.S. aviation.
