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. Pischoffs 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.

The first de Pischoff design; it is shown taxiing, but not flying.

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.
