overtook his records and won the Deutsch-Archdeacon prize for a flight of one kilometre in a closed circuit, Santos Dumont lost his leading position in the world of aviation, after a brief and meteoric career which has stamped his name on history. During these early years the Voisin brothers had the foresight and wisdom to put themselves wholly at the service of others. The promise of flight had taken hold of many minds in France and there was no lack of inventors and would-be inventors who wished to test their own ideas and to have machines built to their own designs. If the Voisins had refused to gratify them, these clients would have disappeared; and the work done for them, though much of it was done in the old blind alleys of horizontal elevating airscrews and wing-flapping machines, yet had this advantage, that it kept the workshop active and made it self-supporting. Inventors are a difficult and jealous people; they received every indulgence from the Voisins. The machines built for them were named after them, though most of the skill and experience that went to the making came from the factory. In the same way M. Archdeacon gave up all practical experiment after 1905 and was content to play the part of the good genius of aviation, presiding at the Aero Club, offering prizes for new achievements, bringing inventors together and encouraging the exchange of ideas. The rapidity of French progress was not a little due to this self-effacing and social instinct, so characteristic of the French spirit, which kept the patron and the engineers in the background, and brought order and progress out of the chaos of personal rivalry.
