Sous Lieutenant Joseph Denis Bernard Robert De Bonnefoy (born 29 October 1894, date of death unknown) was a World War I flying ace credited with six aerial victories. De Bonnefoy was a pre-war cavalryman who volunteered for aviation as soon as the war began. His first flying assignment was to Escadrille 101 to pilot a Voisin. He was removed from the front for a spell as an instructor, then successively assigned to two Nieuport squadrons, Escadrilles 68 and 65. He scored his first aerial victory on 2 July 1916, and gradually accumulated five by 5 November 1916. In 1917, he transferred yet again, to Escadrille 84, and closed out his string with his seventh win on 21 August 1917. The much traveled ace would be temporarily withdrawn for a rest, then assigned to Escadrilles 15 and 31 before end
