Odier-Vendome biplane: Henri Rougier was born in Marseille, the location of the automobile firm Turcat-Mery: he became a race driver, using Turcat-Mery cars. He learned to fly in 1909, and in 1911 a new firm, Turcat-Mery-Rougier, was established north of Paris at Levallois-Perret to build engines and aeroplanes. He commissioned the firm of Vendome to design him a new machine, a biplane which also carried the name of Odier, Vendome's engineer. It appeared in 1910, with wings on each side arched like spoons from a straight center-section; the odd Vendome eyebrow surfaces appeared at the lower wingtips, though it was also built with ailerons. Tiny wheels were set into arched undercarriage legs. Twin boom structures supported the biplane tail with its semicircular central rudder. It was underpowered with its 18 hp Turcat-Mery engine.
