Henry de La Vaulx (1870–1930), was a balloonist, author, and cofounder of major French and international aeronautical associations. Biography He was born in Bierville, France on April 2, 1870. From March 1896 to May 1897 he stayed with native tribes in Patagonia, and later wrote a book about this experience. In 1898, he co-founded the Aero Club of France with Ernest Archdeacon, Léon Serpollet, Henri de la Valette, Jules Verne, Honorine de Viane Morel Verne, André Michelin, Albert de Dion, Alberto Santos-Dumont, and Henry Deutsch de la Meurthe. On Oct 9, 1900 he and a companion set a distance record in a balloon traveling 1200 miles from Vincennes to Korostyshiv near Kiev (Now Ukraine, then in Russia) in 35.75 hours. Also in 1900 he received the Grand Medal of the Aero Club of France for exceptional contributions to the progress of aviation. In 1905 he cofounded and became a director of the Fédération Aéronautique Internationale (FAI). The FAI now awards the De la Vaulx Medal, named for him. He visited the United States several times for ballooning ventures and the New York Times described him as one of the "most successful and daring balloonists in the world." He developed airships for the Zodiac company. He published a dozen books, mostly on aviation. He lived in the castle Rozoy-Bellevalle. He died when a scheduled flight between Montreal, Canada and Newark, NJ that he was on collided with power lines on approach to Newark on April 18, 1930, and was buried in the Rozoy-Bellevalle cemetery.
