Harry George Hawker, MBE, AFC was an Australian aviation pioneer. He was the chief test pilot for Sopwith and was also involved in the design of many of their aircraft. After the First World War, he co-founded Hawker Aircraft, the firm that would later be responsible for a long series of successful military aircraft. He died on 12 July 1921 when the aircraft he was to fly in the Aerial Derby crashed in a park at Burnt Oak, Edgware, not far from Hendon Aerodrome.

The Sopwith Aviation Company was a British aircraft company that designed and manufactured aeroplanes mainly for the British Royal Naval Air Service, the Royal Flying Corps and later the Royal Air Force during the First World War, most famously the Sopwith Camel. Sopwith aircraft were also used in varying numbers by the French, Belgian and American air services during the war.
