De Havilland Biplane No. 1 is a name applied retrospectively to the first aircraft constructed by Geoffrey de Havilland who built and flew it (briefly) in England in 1909. De Havilland undertook the project with the assistance of his flatmate (and soon brother-in-law) Frank Hearle and financed the project with ₤1 000 borrowed from his maternal grandfather as an advance on his inheritance.
Made by Geoffrey de Havilland.
