René Moineau
René Moineau (August 11, 1887 – October 5, 1948) was one of the French pioneers of aviation and an inventor in various branches of aeronautics and fluid mechanics. A pilot and engineer at Bréguet, he designed his own plane, the Salmson-Moineau SM-1, in 1915, then devoted himself to numerous inventions, several patented, including the Moineau pump still used in industry, and the first retractable landing gear (for which he filed the patent in 1918).
