Biography Timeline

1865

Hargrave was born in Greenwich, England, the second son of John Fletcher Hargrave (later Attorney-General of NSW), and was educated at Queen Elizabeth's Grammar School, Kirkby Lonsdale, Westmorland, where there is now a building named in his honour. He immigrated to Australia with his family, arriving in Sydney on 5 November 1865 on the La Hogue. He accepted a place on the Ellesmere and circumnavigated Australia. Although he had shown ability in mathematics at his English school he failed the matriculation examination and in 1867 took an engineering apprenticeship with the Australasian Steam Navigation Company in Sydney. He later found the experience of great use in constructing his models.

1872

In 1872, as an engineer, he sailed on the Maria on a voyage to New Guinea but the ship was wrecked. In 1875, he again sailed as an engineer on William John Macleay's expedition to the Gulf of Papua. From October 1875 to January 1876 he was exploring the hinterland of Port Moresby under Octavius Stone, and in April 1876 went on another expedition under Luigi D'Albertis for over 400 miles up the Fly River on the SS Ellengowan. In 1877 he was inspecting the newly developing pearling industry for Parbury Lamb and Co. He returned to Sydney, joined the Royal Society of New South Wales in 1877, and in 1878 became an assistant astronomical observer at Sydney Observatory. He held this position for about five years, retired in 1883 with a moderate competency, and gave the rest of his life to research work.

1885

Hargrave had been interested in experiments of all kinds from an early age, particularly those with aircraft. When his father died in 1885, and Hargrave came into his inheritance, he resigned from the observatory to concentrate on full-time research. and for a time gave particular attention to the flight of birds. He chose to live and experiment with his flying machines in Stanwell Park, a place which offers excellent wind and hang conditions and nowadays is the most famous hang gliding and paragliding venue in Australia.

He made endless experiments and numerous models, and communicated his conclusions in a series of papers to the Royal Society of New South Wales. Two papers which will be found in the 1885 volume of its Journal and Proceedings show that he was early on the road to success. Other important papers will be found in the 1893 and 1895 volumes which reported on his experiments with flying-machine motors and cellular kites.

1889

Hargrave had not confined himself to the problem of constructing a heavier-than-air machine that would fly, for he had given much time to the means of propulsion. In 1889 he invented a rotary engine which appears to have attracted so little notice that its principle had to be discovered over again by the Seguin brothers in 1908. This form of engine was much used in early aviation until it was superseded by later inventions. His development of the rotary engine was frustrated by the weight of materials and quality of machining available at the time, and he was unable to get sufficient power from his engines to build an independent flying machine.

1894

Of great significance to those pioneers working toward powered flight, Hargrave successfully lifted himself off the ground under a train of four of his box kites at Stanwell Park Beach on 12 November 1894. Aided by James Swain, the caretaker at his property, the kite line was moored via a spring balance to two sandbags (see image). Hargrave carried an anemometer and clinometer aloft to measure windspeed and the angle of the kite line. He rose 16 feet in a wind speed of 21 mph. This experiment was widely reported and established the box kite as a stable aerial platform. Hargrave claimed that "The particular steps gained are the demonstration that an extremely simple apparatus can be made, carried about, and flown by one man; and that a safe means of making an ascent with a flying machine, of trying the same without any risk of accident, and descending, is now at the service of any experimenter who wishes to use it." This was seen by Abbott Lawrence Rotch of the meteorological observatory at Harvard University who constructed a kite from the particulars in Engineering. A modification was adopted by the weather bureau of the United States and the use of box-kites for meteorological observations became widespread. The principle was applied to gliders, and in October 1906 Alberto Santos-Dumont used the box-kite principle in his aeroplane to make his first flight. Until 1909 the box-kite aeroplane was the usual type in Europe.

1895

Hargrave was an excellent experimenter and his models were well crafted. He had the optimism that is essential for an inventor, and the perseverance that will not allow itself to be damped by failures. Modest, unassuming and unselfish, he always refused to patent his inventions, and was only anxious that he might succeed in adding to the sum of human knowledge. Many men smiled at his efforts and few had faith that anything would come of them. An honourable exception was Professor Richard Threlfall who, in his presidential address to the Royal Society of New South Wales in May 1895, spoke of his "strong conviction of the importance of the work which Mr Hargrave has done towards solving the problem of artificial flight". Threlfall called Hargrave the "inventor of human flight", and the debt supposed to be owed by the Wright brothers to Hargrave. The step he made in man's conquest of the air was an important one with far-reaching consequences, and he should be remembered as an important experimenter and inventor, who "probably did as much to bring about the accomplishment of dynamic flight as any other single individual".

1915

Hargrave's only son Geoffrey was killed at the Battle of Gallipoli in May 1915 during World War I. Hargrave was operated on for appendicitis but suffered peritonitis afterwards and died in July 1915. He was interred in Waverley Cemetery on the cliffs overlooking the open ocean.

Family Life

Lawrence grew up in both England and Australia. Lawrence's father, John Fletcher Hargrave, held office as Attorney General of New South Wales, Australia.
