Léon Delagrange, Ferdinand Marie Léon Delagrange, born 13 March 1872 in Orléans (Loiret) and deceased 4 January 1910 at Croix d'Hins (Gironde), was an aero inventor, aviator, and sculptor, also factoring into the history of Appareils d'Aviation Les Frères Voisin, and setting airplane flight distance records in 1907.

In 1908 he entered a friendly competition with Henry Farman as both undertook regular flights at Issy-les-Moulineaux, grounds provided by the French Minister of War to the Aéro-Club de France. On 17 March 1908 he won a 200-franc prize from the Aéro-Club for flying more than 200 meters as a beginner. On 21 March he raced Farman, who flew 2004.8 meters; Delagrange then flew 1,500 meters; the two then flew 50 meters together—the first airplane flihgt with two men aboard.[1]

On 11 April 1908 he flew 2,500 meters but touched the ground midway, disqualifying him from setting a new record. On 12 April he officially break Farman's record with a flight of 5,575 meters, 3,925 of them continuous without touching the ground. He then made some demonstrations in Italy, including a 12.75 km flight on 30 May 1908. Finally, he flew 14.8 miles on 6 September 1908, at Issy-les-Moulineaux.[1]
