Sloan et Cie

Sloan & Cie, Ingénieurs-Constructeurs of 17 rue de Louvre, Paris, was a maker of hydraulic turbines and was established prior to 1900.

Built several models of tractor biplanes, 1910-1912, nicknamed "Bicurve" because of the slightly arched upper wing that attached at each end to the lower wing; also built conventional military 3-seater biplane, 1911, and made propellers.

SD attributes the Bicurve to Sloan & Cie

• Gunston, 2005, p attributes it to the founder of Sloan Aircraft Co. in the U.S., apparently meaning John Eyre Sloane. Other sources attribute the bicurve to John Sloan, an American. On the other hand, it could be Sloan Aeroplane (International) Syndicate registered in early January 1911 at 26 Budge Row, London, E.C. Or Sloan Aeroplane Syndicat, 17 Rue de Louvre, Paris.

Further research Brockett's 1921 Bibliography of Aeronautics is possible. The history of Port Aviation sy portaviation.com (says?) the airfield where a Bicurve Sloan, manufactured by Sloan and Cie, was flown over several days in December 1910.
