De Pischoff
Alfred de Pischoff was born in Austria of French parents; by 1907 he had moved back to France and had designed and had built a biplane glider like Ferber's, which he had intended to power with a 25 hp Anzani.
De Pischoff No 1: In 1907 he designed a small biplane with the same Anzani and had it built at the Chauviere works; it may indeed have been the glider re-worked. It looked surprisingly modern with its overhung top wings, tractor propeller and neat tricycle undercarriage. The wings arched gracefully upward at the tips, and the pilot sat somewhat precariously between them on a raised seat immediately aft of the motor. From his seat a long fan shaped tailplane with rectangular elevators ran back, joined at the trailing edges by a thin spar which ran through a cut-out in the fin. It was damaged in a test in November 1907, and did not actually fly.

Alfred de Pischoff drove out to Issy in 1907 and 1908 to test what was then a revolutionary biplane he had had built in the workshops of Lucien Chauviere. It had wings of unequal span, the upper wing being longer. There was nothing of the box-kite about it. There was an open configuration about this machine, and the floating tail went back even to Cayley. This was the first full-scale biplane with a tractor propeller, and Chauviere had improved on the warped canoe-paddles that were used up to that time - and well beyond that time in England - and had produced the first ‘sophisticated’ airscrew used in Europe. Pischoff’s aircraft had no forward control surfaces, and in appearance it set the standard for the new look of a whole generation of practical biplanes. But the unsavoury truth about this machine was that in itself it was not exactly practical. Its best flight at Issy was a hop of 7m in December 1907.

PISCHOFF-KOECHLIN (1908). Very early example of a tractor biplane. The extra span of the upper plane is also of interest. The machine had twin mono-elevators aft and also twin rudders.
The Pischoff I biplane of 1907, though not quite a flyer, set the style of future biplanes with its clean configuration, uncluttered by forward control areas or box-kite cellules, its Chauviere Integrate tractor propeller making it what is now regarded as the first in Europe of a modern design. The tail unit was a Cayley-type cruciform union of tailplane, fin, elevator and rudder. There were no ailerons, no wingwarping, and consequently no pilot-operated lateral control. The Pischoff I introduced the famous Anzani engine into aeronautics.
