Lawrence Hargrave (1850- 1915), an English-born Australian aeronautical pioneer, developed the box kite to produce a wing form for early aircraft. Hargrave's box kite formed the basis of a number of succesful power driven aeroplanes developed in the first decade of the 20th century, including the 'No 14 bis' plane flown in France by Alberto Santos-Dumont in September 1906. In honour of his achievements, a portrait of Hargrave appeared on the $20 Australian note.
