Seux

   The details of the career of Edmond Seux are not clear, and it is difficult to sort out his designs. Born in Annonay, the home city of the Montgolfier brothers, he is said to have begun early with models. In June 1904 he had the Surcouf firm build him a triplane "parachute a reaction," fitted with "lateral planes." It was tested unsuccessfully in February 1905.
   In 1907 he had the firm of Ronnet at Lyon build him a monoplane; it had a "waving wing" with flexible tips "for stability" mounted on a complex uncovered frame set on 4 wheels, 2 large ones in front, 2 smaller behind. 2 pusher propellers were mounted on shafts driven by twin belts and large pulleys. A forward elevator was on triangular outriggers and a cruciform tail was mounted on a pair of horizontal booms. The wing leading edge was thick, and the wing plan was that of a large bird. The aeroplane was tested on 15 May at Grandchamps, a nearby parade ground; it is reported that the front wheels lifted off and the tiny rear wheels collapsed. Seux planned to refit tandem wheels, but did not get to do this.

   In 1908 he had the workshops of Pierre and Louis Reusch build him a biplane, known as the Reusch et Seux. In the same year the 3 men also patented a pusher biplane patterned on the Wright, possibly not built, his first biplane not having been completed either. The Reusch et Seux had a forward elevator and a transverse engine driving 2 pusher propellers.

   (Span: 10 m; length: 9 m; wing area reported as 50 sqm; 50 hp engine)
  
   On 6 Nov 1909, Edmond Seux's body was found in the Rhone river: it was said he had killed himself because he could not repay his loans. He was 42 years old.
