  Lawrence Hargrave - Wikipedia, the free encyclopedia
Lawrence Hargrave (1850 - 1915) was an engineer, explorer, astronomer, and aeronautical pioneer.
In an astonishingly productive career, Hargrave invented many devices, but never once applied for a patent on any of them: he did not need the money, and he was a passionate believer in scientific communication as a key to furthing progress.
Hargrave was devoted to his family, and when his son Geoffrey was killed at Gallipoli in May 1915 he was heartbroken, and died soon after hearing the news.

 The Australian Institute of Political Science
Hargrave's intended law career was scuttled when he failed his matriculation examination, and instead he was apprenticed as an engineer to the Australian Steam Navigation Company, where over the next five years he acquired the practical and design skills that were to prove invaluable later.
Hargrave's father had made a number of shrewd land purchases, and provided well for his sons, such that by 1883 Lawrence was able to cease paid employment to concentrate on inventions.
Hargrave was a passionate advocate of freedom of communication within the scientific community, and an equally passionate adversary of the patenting system, preferring his inventions to be available for the benefit of all.

 Lawrence Hargraves and kites
Lawrence Hargraves was born in England, 1850 the son of a judge.
Hargraves kept all his detailed notes of all the experiments that took place and even flew himself beneath a train of box kites to a height of 16ft.
Hargraves made a major contribution to the study of aerodynamics (the study of the effect that a solid body has on air, when travelling through it), when his experiments were influential in the development of the cambered aerofoil (a structure with curved surfaces which gives lift when in flight).

Lawrence Hargrave was born in Greenwich England on January 29, 1850 and educated in England at Queen Elizabeth's Grammar School, Kirkby Lonsdale, Westmoreland.
Hargrave is probably correct in his reasoning; for the history of all new methods of transportation teaches that the original inventor seldom receives pecuniary reward for the contrivance which is the first to succeed, but nevertheless he is certainly broadly liberal in giving to the world gratuitously the results of his constant studies and labors.
Hargrave stretched the rubber so that its elongation was multiplied by pulley tackle, and that, as the rubber contracted, its center of gravity moved forward, thus advancing the center of gravity of the entire machine, and consequently diminishing the angle of flight as the force of the rubber decreased.

Hargrave was also an historian, and remarked that the inventor of a new mode of transportation had never been made rich by that invention, patented or not.
One of Hargrave's earliest achievements was to demonstrate that for a wing to lift and move through air efficiently, the center of pressure ought to be located at about 25% of the chord length of the wing section.
