Antoinette monoplane

Antoinette was a French manufacturer of light petrol engines. Antoinette also became a pioneer-era builder of aeroplanes before World War I, most notably the record-breaking monoplanes flown by Hubert Latham and René Labouchère. Based in Puteaux, the Antoinette concern was in operation between 1903 and 1912. The company operated a flying school at Chalons for which it built one of the earliest flight simulators.

Antoinette began as a private venture led by the engineer Léon Levavasseur and financed by Jules Gastambide, who owned an electricity generating station in Algeria. While on holiday with Gastambide and his family in 1902, Levavasseur expressed his interest in the emerging field of aviation and proposed the development of light, powerful engines for use in aircraft. Levavasseur then suggested to Gastambide's daughter, Antoinette, that the engines should be named after her. Gastambide financed the venture. Levavasseur patented the V8 engine configuration that year. By 1904, most of the prize-winning speedboats in Europe were powered with Antoinette engines. During this time, he designed engines of various configurations of up to thirty-two cylinders.

La Société Antoinette was incorporated in 1906, with Gastambide as president and Levavasseur as technical director. Aviation pioneer Louis Blériot was the vice-president .

Antoinette displayed an automobile with a 7.2 L (439 cu in), 32 horsepower (24 kW) V8 engine in the 1906 Paris Salon de l'Automobile of that year.

The company's primary business was the sale of engines to aircraft builders. Their engines were used in the Santos-Dumont 14-bis of 1906, Paul Cornu's rudimentary helicopter of 1907, the Voisin biplane that was modified and piloted by Henri Farman who used it to complete Europe's first 1 kilometer circular flight in January 1908, and other significant pioneer aircraft.
