Adolphe Celestin Pegoud (1889-1915), French aviator, in an aeroplane. Pegoud is best known for being the first ace fighter pilot. He began flying in 1913, and at the start of World War I he volunteered for flying duty. He was soon flying solo and claiming a succession of victories against the German planes. This success came to an end on 31 August when his plane was in turn shot down. Photograph from the Bain News Service.
