Brothers Gaston (1882-1915) and René Caudron (1884-1959) started the Société des Avions Caudron after initially experimenting with aviation as early as 1908.  They produced successful designs, mainly reconnaissance and bomber aircraft, during World War I, a variety of types in the interwar years including a line of racing planes, and some fighters that saw limited service early in World War II, by which time Caudron had been acquired by the Renault auto company.  Caudron did not reappear in the aviation scene after World War II.
