George Cayley (1773–1857)
Born 1773 CE, died 1857 CE.
Sir George Cayley, 6th Baronet (27 December 1773 – 15 December 1857) was an English engineer, inventor and aviator. He was a pioneer of aeronautical engineering and is sometimes referred to as "the father of aviation", designing the first glider reliably reported to carry a human aloft. He is commonly credited as the first person to understand the underlying principles and forces of heavier-than-air flight: weight, lift, drag and thrust. He was also the inventor of the wire wheel. In 1799, he set forth the concept of the modern aeroplane as a fixed-wing flying machine with separate systems for lift, propulsion and control. Modern aeroplane design is based on those discoveries and on the cambered wings he proposed. He constructed the first flying model aeroplane and also diagrammed the elements of vertical flight. He correctly predicted that sustained flight would not occur until a lightweight engine was developed to provide adequate thrust and lift.
