Arthur Oskar Deicke (January 18, 1882 in Altena; March 9, 1958 in Munich) was a German designer of engines, motorcycles, speedboats, and aircraft.
Arthur Deicke was born the son of basket maker Emil Deicke (1849-1887) and Clara Ida Deicke, née Weissbach (1859-1931). His most important work was the ADM11, a single-seater aircraft that consumed 6 liters of fuel per 100 km at a cruising speed of 90 km/h.[1] It was the first aircraft with an enclosed cockpit. Deicke's legacy is preserved in the Deutsches Museum in Munich.
