Rene Hanriot (-1925) raced automobiles and boats around the turn of the century and, like many others who felt the need for speed in those years, began experimenting in aviation in 1907.  After cutting his teeth on a Bleriot clone, Hanriot designed a series of monoplanes that had modest success during the prewar years.  During World War I he teamed up with designer Emile Dupont to create the H.D. series of fighters, and the company continued to build military aircraft following the war.  After Hanriot’s death, the company entered into a series of mergers until it disappeared in the French government’s 1936 consolidation and nationalization of aircraft manufacturers.
