But his strongest arguments were directed against the patenting system. He published all his theoretical work and divulged the results of all his experiments in the Journal and Proceedings of the Royal Society of New South Wales with the deliberate intention of foiling a 'master patent thereby throwing back our work for years'.
In he presented to the Royal Society his elaborately constructed, circumstantial and obsessively held Lope de Vega theory, many years in the forming, that two Spanish ships, the Santa Ysabel and Santa Barbara , had found their way into Sydney Harbour, stayed several years and left in , only to be wrecked on their voyage home. Hargrave's social Darwinism and his literal engineer's mind refused to entertain the use of flying machines for war.
When hostilities began in , he returned the Bavarian award which he had received in recognition of his pioneering aeronautical work and, even before Australia declared war, reported himself for service; he was then almost On 7 September Hargrave had married with Presbyterian forms Margaret Preston, daughter of David Johnston, a Sydney shipping clerk; the marriage seems to have been devoid of romance in its beginning and short on pleasure or comradeship.
Six children were born, one of whom died in infancy; and their only son Geoffrey was killed in action at Gallipoli in May Hargrave died on 14 July at Darlinghurst from peritonitis following an operation for appendicitis and was buried in Waverley cemetery.
Margaret took her youngest daughter and her husband's papers, diaries and journals to England, where she settled. During his life, Hargrave felt isolated from his surroundings and unrecognized.

At the age of 30, he inherited enough money to support his family while pursuing his passion for invention. At the time, early aviators were experimenting with mono-winged gliders, which were proving unstable and unsafe, and trying to develop an engine powerful enough to achieve lift.
Hargrave conducted many experiments and made countless models of his ideas. He studied aerofoils and developed a wave-propelled boat, a screw-driven engine, a working model aircraft with flapping wings, and a rotary engine so ahead of its time it was re-created by another inventor in and used in aviation for many years. Hargrave is best remembered for solving the problem of creating man-made wings that provided lift, safety and stability. On that beach at Stanwell Park, Hargrave climbed into a sling seat attached to an elaborate series of four box kites carrying instruments to measure wind speed and altitude.
With the help of his employee, James Swaine, Hargrave rose safely into the air — more than 16 feet into the air — becoming the first person in history to be lifted off the ground by a stable fixed wing device. Hargrave firmly believed that scientific discovery should be disseminated freely, so he never received wide recognition for his work. It laid the groundwork for the first powered biplane flight at Kittyhawk in Monash University's Pioneers, Aviation and Aeromodelling.
The National Museum of Australia acknowledges First Australians and recognises their continuous connection to country, community and culture. Octave Chanute, American aviation pioneer:. Lawrence Hargrave and his kites at Stanwell Park, south of Sydney.
Lawrence Hargrave, about From Hargrave had been intrigued by the motion of animals: It will be evident that a remarkable analogy exists between walking, swimming and flying. Group of cellular kites designed by Lawrence Hargrave. Box kites In the s the poor power-to-weight ratio of most engines and inefficient propeller design meant that aeronautical pioneers focused more on the study of gliding and wing design rather than powered flight.
Hargrave produced a series of monoplane gliders, but unhappy with their stability began to study box kites instead: I am using kites, and find perfect stability can be got by making them of three dimensions instead of two … cellular kites do not confine their surface to one plane, but distribute it in various portions, forming cells through which the wind blows.
