Asa North Duncan was born on March 30, 1892, in Leighton, Colbert County, Alabama. He was the son of Asa Jasper Duncan and Emma Gertrude Johnson Duncan. He was married to Almeda Sadler Duncan. He began his military career in the Alabama Infantry before transferring to aviation service during World War I. After training as an aerial observer, he served with the 91st Aero Squadron in France. He participated in the Meuse-Argonne Offensive, earning a citation for outstanding service on combat missions over enemy territory.

After the war, Duncan pursued a career in military aviation, graduating from both flight training and bombardment school in 1921. Over the next two decades, he held numerous command, instructional, and staff assignments, including command of the 20th Bombardment Squadron, service with the Office of the Chief of the Air Corps, and leadership positions at Luke Field, Hawaii, and March Field, California. He also completed advanced professional military education at the Air Corps Tactical School and the Command and General Staff School.

In August 1941, Duncan became commander of Savannah Air Base, Georgia, and shortly thereafter assumed command of the newly established 3rd Air Support Command. On January 28, 1942, he was selected as the first commander of the newly activated Eighth Air Force, which would later become one of the most important American air forces operating in Europe during World War II. After the Eighth Air Force deployed overseas, Duncan served as Chief of Staff under Major General Carl Spaatz in the European Theater.

On November 17, 1942, while traveling aboard a B-17 Flying Fortress from the United Kingdom to Gibraltar, Duncan was killed when the aircraft crashed into the ocean, resulting in the loss of all aboard. He is honored at the Cambridge American Cemetery and Memorial in Cambridgeshire, England. During his distinguished military career, Duncan earned ratings as both a Command Pilot and Combat Observer and played a significant role in the early development of the Eighth Air Force. He also has a cenotaph in the Oakwood Cemetery, Sheffield, Colbert County, Alabama, USA.
