Félix du Temple de la Croix (18 July 1823 – 3 November 1890) (usually simply called Félix du Temple) was a French naval officer and an inventor, born into an ancient Norman family. He developed some of the first flying machines and is credited with the first successful flight of a powered aircraft of any sort, a powered model plane, in 1857 and is sometimes credited with the first manned powered flight in history aboard his Monoplane in 1874.
He was a contemporary of Jean-Marie Le Bris.
