62 Goddard, Dr Robert Hutchings
SUBJECT AREA: Aerospace[br]b. 5 October 1882 Worcester, Massachusetts, USAd. 10 August 1945 Baltimore, Maryland, USA[br]American inventory developer of rocket propulsion.[br]At the age of seventeen Goddard climbed a tree and, seeing the view from above, he became determined to make some device with which to ascend towards the planets. In an autobiography, published in 1959 in the journal Astronautics, he stated, "I was a different boy when I descended the ladder. Life now had a purpose for me." His first idea was to launch a projectile by centrifugal force, but in 1909 he started to design a rocket that was to be multi-stage and fuelled by liquid oxygen and hydrogen. Not long before the First World War he produced a report, "A method of reaching extreme altitudes", which was for the Smithsonian Institution and was published in book form in 1919. During the war he worked on solid-fuelled rockets as weapons. His book contained notes on the amount of fuel required to raise 1 lb (454 g) of payload to an infinite altitude. He incurred ridicule as "the moon man" when he proposed the use of flash powder to indicate successful arrival on the moon. In 1923 he severed his connections with military work and returned to the University of Massachusetts. On 16 March 1926 he launched the world's first liquid-fuelled rocket from his aunt's farm in Auburn, Massachusetts; powered by gasoline and liquid oxygen, it flew to a height of 12 m (40 ft) and travelled 54 m (177 ft) in 2.4 seconds.In November 1929 he met the aviator Charles Lindbergh, who persuaded both the Guggenheim Foundation and the Carnegie Institute to support Goddard's experiments financially. He moved to the more suitable location of the Mescalere Ranch, near Roswell, New Mexico, where he worked until 1941. His liquid-fuelled rockets reached speeds of 1,100 km/h (700 mph) and heights of 2,500 m (8,000ft). He investigated the use of the gyroscope to steady his rockets and the assembly of power units in clusters to increase the total thrust. In 1941 he moved to the naval establishment at Annapolis, Maryland, working on liquid-fuelled rockets to assist the take-off of aircraft from carriers. He worked for the US Government on this and the development of military rockets until his death from throat cancer in 1945. In all, he was granted 214 patents, roughly three per year of his life.In 1960 the US Government admitted infringement of Goddard's patents during the rocket programme of the 1950s and awarded his widow a payment of $1,000,000, while the National Aeronautics and Space Administration (NASA) honoured him by naming the Goddard Spaceflight Center near Washington, DC, after him. The Goddard Memorial Library at Clark University, in his home town of Worcester, Massachusetts, was also named in his honour.[br]Further ReadingA.Osman, 1983, Space History, London: Michael Joseph.

63 Harris, Alanson
SUBJECT AREA: Agricultural and food technology[br]b. 1816 Ingersoll, Ontario, Canadad. 1894 Canada[br]Canadian manufacturer of agricultural machinery and co-founder of the Massey Harris Company (later Massey Ferguson).[br]Alanson Harris was the first often children born to the wife of a circuit rider and preacher. His father's wanderings left Alanson at an early age in charge of the running of the family farm on the Grand River in Canada; also, his father's preference was for tinkering with machines rather than for farming. However, when he was 13 Alanson had to go out to work in order to bring badly needed cash to augment the family income. He worked at a sawmill in the small village of Boston, becoming Boss Sawyer and then Foreman after ten years. In 1839 the family moved to Mount Pleasant, and the following year Alanson married Mary Morgan, the daughter of a well-to-do pioneer Welsh farmer. He entered into a brief partnership with his father to build a sawmill at Whiteman's Creek, but within a few months his father returned to preaching and Alanson became the sole proprietor. After a successful early period Alanson recognized the signs of decline in the timber market, and in 1857 he sold the mill, moved to Beamsville, Niagara, and bought a small factory from which he produced the flop-over hay rake invented by his father. In 1863 he took his eldest son into partnership; the latter returned from a visit to the United States with the sole rights to produce the Kirby mower and reaper. The Crimean War created a market for corn, which gave a great boost to North American farming and, in its turn, to machinery production. This was reinforced by the tariff agreements between the United States and Canada. By the 1880s Harris and Massey between them accounted for two thirds of the harvesting machines sold in Canada, and they also supplied machines abroad. By the end of the decade the mutual benefits of joining forces were apparent and by 1891 an agreement was reached, with Alanson Harris and A.H.Massey on the first board.[br]Further ReadingG.Quick and W.Buchele, 1978, The Grain Harvesters, American Society of Agricultural Engineers (refers to Harris and Massey Harris Company in its account of the development of harvest machinery).M.Denison, 1949, Harvest Triumphant: The Story of Massey Harris, London (gives a more detailed account of Massey Harris Company).AP -
64 Pilcher, Percy Sinclair
SUBJECT AREA: Aerospace[br]b. 16 January 1867 Bath, Englandd. 2 October 1899 Stanford Hall, Northamptonshire, England[br]English designer and glider aeronaut.[br]He was educated at HMS Britannia Royal Naval College, Dartmouth, from 1880 to 1882. He sailed on HMS Duke of Wellington, Agincourt, Northampton and other ships and resigned from the navy on 18 April 187 after seven years at sea. In June 1887 he was apprenticed at Randolph, Elder \& Co.'s shipyard at Govan, and was then an apprentice moulder at Cairn \& Co., Glasgow. For some time he "studied" at London University (though there is no official record of his doing so) while living with his sister at Phillbeck Gardens, South Kensington. In May 1890 he was working for John H.Biles, Manager of the Southampton Naval Works Ltd. Biles was later appointed Professor of Naval Architecture at Glasgow University with Pilcher as his Assistant Lecturer. In 1895 he was building his first glider, the Bat, which was built mainly of Riga pine and weighed 44 lb (20 kg). In succeeding months he travelled to Lichterfelde to study the gliders made by the German Lilienthal and built a further three machines, the Beetle, the Gull and the Hawk. In 1896 he applied for his only aeronautical patent, for "Improved flying and soaring machines", which was accepted on March 1897. In April 1896 he resigned his position at Glasgow University to become Assistant to Sir Hiram Maxim, who was also doing experiments with flying machines at his Nordenfeld Guns and Ammunition Co. Ltd at Crayford. He took up residence in Artillery Mansions, Victoria Street, later taken over by Vickers Ltd. Maxim had a hangar at Upper Lodge Farm, Austin Eynsford, Kent: using this, Pilcher reached a height of 12 ft (3.66m) in 1899 with a cable launch. He planned to build a 2 hp (1.5 kW) petrol engine In September 1899 he went to stay with Lord Braye at Stanford Hall, Northamptonshire, where many people came to see his flying machine, a triplane. The weather was far from ideal, windy and raining, but Pilcher would not disappoint them. A bracing wire broke, the tail collapsed and the pilot crashed to the ground suffering two broken legs and concussion. He did not regain consciousness and died the following day. He was buried in Brompton Cemetery.[br]Bibliography1896, British patent no. 9144 "Improved flying and soaring machines".Further ReadingP.Jarrett, 1987, Another Icarus.

65 Roebling, John Augustus
SUBJECT AREA: Civil engineering[br]b. 12 July 1806 Muhlhausen, Prussiad. 22 July 1869 Brooklyn, New York, USA[br]German/American bridge engineer and builder.[br]The son of Polycarp Roebling, a tobacconist, he studied mathematics at Dr Unger's Pedagogium in Erfurt and went on to the Royal Polytechnic Institute in Berlin, from which he graduated in 1826 with honours in civil engineering. He spent the next three years working for the Prussian government on the construction of roads and bridges. With his brother and a group of friends, he emigrated to the United States, sailing from Bremen on 23 May 1831 and docking in Philadelphia eleven weeks later. They bought 7,000 acres (2,800 hectares) in Butler County, western Pennsylvania, and established a village, at first called Germania but later known as Saxonburg. Roebling gave up trying to establish himself as a farmer and found work for the state of Pennsylvania as Assistant Engineer on the Beaver River canal and others, then surveying a railroad route across the Allegheny Mountains. During his canal work, he noted the failings of the hemp ropes that were in use at that time, and recalled having read of wire ropes in a German journal; he built a rope-walk at his Saxonburg farm, bought a supply of iron wire and trained local labour in the method of wire twisting.At this time, many canals crossed rivers by means of aqueducts. In 1844, the Pennsylvania Canal aqueduct across the Allegheny River was due to be renewed, having become unsafe. Roebling made proposals which were accepted by the canal company: seven wooden spans of 162 ft (49 m) each were supported on either side by a 7 in. (18 cm) diameter cable, Roebling himself having to devise all the machinery required for the erection. He subsequently built four more suspension aqueducts, one of which was converted to a toll bridge and was still in use a century later.In 1849 he moved to Trenton, New Jersey, where he set up a new wire rope plant. In 1851 he started the construction (completed in 1855) of an 821 ft (250 m) long suspension railroad bridge across the Niagara River, 245 ft (75 m) above the rapids; each cable consisted of 3,640 wrought iron wires. A lower deck carried road traffic. He also constructed a bridge across the Ohio River between Cincinnati and Covington, a task which was much protracted due to the Civil War; this bridge was finally completed in 1866.Roebling's crowning achievement was to have been the design and construction of the bridge over the Hudson River between Brooklyn and Staten Island, New York, but he did not live to see its completion. It had a span of 1,595 ft (486 m), designed to bear a load of 18,700 tons (19,000 tonnes) with a headroom of 135 ft (41 m). The work of building had barely started when, at the Brooklyn wharf, a boat crushed Roebling's foot against the timbering and he died of tetanus three weeks later.
