Sir George Cayley, Bt., Brompton Hall, Yorkshire, 1773-1857, published series of visionary drawings of fixed-wing aerodynes from 1791, including classic treatise 1809-10; published design of 'governable parachute' monoplane glider 25 September 1852, this reportedly flown with ballast, with small boy and with Cayley’s coachman, thus first full-scale aerodyne in history.
