Sir George Cayley, 6th Baronet (27 December 1773 – 15 December 1857) was a prolific English engineer and is one of the most important people in the history of aeronautics. Many consider him to be the first true scientific aerial investigator and the first person to understand the underlying principles and forces of flight.
