Voisin-Farman 1




Two identical pusher biplane machines, with Antoinette engines, had been built by the Voisin brothers for two early aviation pioneers, one for Léon Delagrange in March 1907, and the second for his friend and rival the Anglo-French pioneer Henry Farman (1874-1958) in October 1907. The latter biplane became known as the Voisin-Farman I and Farman made a number of modifications of his own during the autumn of that year. Thus, the Voisin-Farman 1 became the Voisin-Farman 1bis; it was flown by Farman on 13 January 1908 to win the Archdeacon's Grand Prix d'Aviation prize for making the successful first one-kilometer closed-circuit flight.


Built for Farman by Voisin Frères, Charles and Gabriel – often referred to as the Voisin-Farman 1 or Voisin HF-1 – yet sometimes called the Farman HF-1, since after delivery from the Voisin Factory, Henry Farman made significant modifications to the machine. This Voisin-built Farman had no ailerons and no wing warping, the only thing to do was to fly a very steady level turn.
In this form it became the first aeroplane, after the Wright Flyer No. 2, 1904, to remain airborne for over a minute and turn a complete circle. The latter flight, made on 13th January, 1908, won Farman the Deutsch‑Archdeacon prize of 50,000 francs for completing the first official circle of one kilometre in diameter.
The photograph shows Farman at the moment he crosses the start/finish line at Issy-les-Moulineaux in completing, on January 13, 1908, the first 1 km circuitous flight, thus winning the Grand Prix d'Aviation that had been offered by Henri Deutsch de la Meurthe. Although the two points (start and return) were exactly at 500 m distance, Farman was unable to fly the aeroplane in that way. Observers in the photo from left to right are: René Demanest, André Fournier, Louis Blériot (commissaire au départ et à l'arrivée) and Charles Voisin. In the car are Ernest Archdeacon (one of the prize sponsors) and his wife.
