4 Deere, John
SUBJECT AREA: Agricultural and food technology[br]b. 7 February 1804 Rutland, Vermont, USAd. 17 May 1886 USA[br]American inventor and manufacturer of agricultural equipment.[br]John Deere was the son of a tailor, and first worked as a tanner before becoming apprenticed to a blacksmith. He married Demarius Lamb in 1827, but it appears that competition for blacksmiths was fierce, and the Deere family moved frequently. Two attempts to establish forges ended in fires, and changing partnerships and arguments over debts were to be a feature of Deere's working life. In 1836 John Deere moved west on his own, in an attempt to establish himself. He settled in Grand Detour, Illinois. In this new frontier a blacksmith's skills were sought after, and the blacksmith, with no ready supply of raw materials, had to be able to operate both a furnace for melting metal and a forge for working it. Deere was sufficiently successful for his family to be able to join him. A chance visit to a sawmill and the acquisition of a broken saw blade led to the making of a plough that was to establish John Deere in manufacturing. There were two distinctive features associated with the plough: the soil in the area failed to stick to the steel blade, with obvious benefits to the draught of the implement; and second, the shape of the working mouldboard was square. The reputation that developed with his first three ploughs established that Deere had made the transition from blacksmith to manufacturer.Over the next decade he had a number of partnerships and eventually set up a factory in Moline, Illinois, in 1848. The following year he sold 2,136 ploughs, and by early 1850 he was producing 350 ploughs per month. Deere was devastated by the loss of his eldest son in the year that the company moved to Moline. However, his second son, Charles, joined him in 1851 and was to be a major influence on the way in which the company developed over the next half-century. The company branched out into the production of cultivators, harrows, drills and wagons. John Deere himself played an active part in the company, but also played an increasing role in public life, with a particular interest in education. The company was incorporated in 1868.[br]Further ReadingThe following both provide biographical details of John Deere, but are mainly concerned with the company and the equipment it produced: W.G.Broehl, 1984, John Deere's Company: A History of Deere and Company and itsTimes, American Society of Agricultural Engineers.D.Macmillan, 1988, John Deere Tractors and Equipment, American Society of Agricultural Engineers.AP -
5 Slater, Samuel
SUBJECT AREA: Textiles[br]b. 9 June 1768 Belper, Derbyshire, Englandd. 21 April 1835 USA[br]Anglo-American manufacturer who established the first American mill to use Arkwright's spinning system.[br]Samuel's father, William, was a respected independent farmer who died when his son was aged 14; the young Slater was apprenticed to his father's friend, Jedediah Strutt for six and a half years at the beginning of 1783. He showed mathematical ability and quickly acquainted himself thoroughly with cotton-spinning machinery made by Arkwright, Hargreaves and Crompton. After completing his apprenticeship, he remained for a time with the Strutts to act as Supervisor for a new mill.At that time it was forbidden to export any textile machinery or even drawings or data from England. The emigration of textile workers was forbidden too, but in September 1789 Slater left for the United States in disguise, having committed the details of the construction of the cotton-spinning machinery to memory. He reached New York and was employed by the New York Manufacturing Company.In January 1790 he met Moses Brown in Providence, Rhode Island, and on 5 April 1790 he signed a contract to construct Arkwright's spinning machinery for Almy \& Brown. It took Slater more than a year to get the machinery operational because of the lack of skilled mechanics and tools, but by 1793 the mill was running under the name of Almy, Brown \& Slater. In October 1791 Slater had married Hannah Wilkinson, and in 1798 he set up his own mill in partnership with his father-in-law, Orziel Wilkinson. This mill was built in Pawtucket, near the first mill, but other mills soon followed in Smithville, Rhode Island, and elsewhere. Slater was the Incorporator, and for the first fifteen years was also President of the Manufacturer's Bank in Pawtucket. It was in his business role and as New England's first industrial capitalist that Slater made his most important contributions to the emergence of the American textile industry.[br]Further ReadingG.S.White, 1836, Memoirs of Samuel Philadelphia (theearliestaccountofhislife).

10 Allen, John F.
SUBJECT AREA: Steam and internal combustion engines[br]b. 1829 Englandd. 2 October 1900 New York (?), USA[br]English inventor of the Allen valve used on his pioneering high-speed engines.[br]Allen was taken to the United States from England when he was 12 years old. He became an engineer on the Curlew, a freight boat running between New York and Providence. A defect which caused the engine to race in rough weather led Allen to invent a new valve gear, but he found it could not be fitted to the Corliss engine. In 1856 he patented an improved form of valve and operating gear to reduce back-pressure in the cylinder, which was in fact the reverse of what happened in his later engines. In 1860 he repaired the engines of a New York felt-hat manufacturer, Henry Burr, and that winter he was introduced to Charles Porter. Porter realized the potential of Allen's valves for his idea of a high-speed engine, and the Porter-Allen engine became the pioneer of high-speed designs.Porter persuaded Allen to patent his new valves and two patents were obtained in 1862. These valves could be driven positively and yet the travel of the inlet could be varied to give the maximum expansion at different cut-offs. Also, the valves allowed an exceptionally good flow of steam. While Porter went to England and tried to interest manufacturers there, Allen remained in America and continued work on the engine. Within a few years he invented an inclined watertube boiler, but he seemed incapable of furthering his inventions once they had been placed on the market. Although he mortgaged his own house in order to help finance the factory for building the steam engine, in the early 1870s he left Porter and built a workshop of his own at Mott Haven. There he invented important systems for riveting by pneumatic machines through both percussion and pressure which led into the production of air compressors and riveting machines.[br]Further ReadingObituaries appeared in engineering journals at the time of his death.Dictionary of American Biography, 1928, Vol. I, New York: C.Scribner's Sons.

11 Bury, Edward
[br]b. 22 October 1794 Salford, Lancashire, Englandd. 25 November 1858 Scarborough, Yorkshire, England[br]English steam locomotive designer and builder.[br]Bury was the earliest engineer to build locomotives distinctively different from those developed by Robert Stephenson yet successful in mainline passenger service. A Liverpool sawmill owner, he set up as a locomotive manufacturer while the Liverpool \& Manchester Railway was under construction and, after experiments, completed the four-wheeled locomotive Liverpool in 1831. It included features that were to be typical of his designs: a firebox in the form of a vertical cylinder with a dome-shaped top and the front flattened to receive the tubes, and inside frames built up from wrought-iron bars. In 1838 Bury was appointed to supply and maintain the locomotives for the London \& Birmingham Railway (L \& BR), then under construction by Robert Stephenson, on the grounds that the latter should not also provide its locomotives. For several years the L \& BR used Bury locomotives exclusively, and they were also used on several other early main lines. Following export to the USA, their bar frames became an enduring feature of locomotive design in that country. Bury claimed, with justification, that his locomotives were economical in maintenance and fuel: the shape of the firebox promoted rapid circulation of water. His locomotives were well built, but some of their features precluded enlargement of the design to produce more powerful locomotives and within a few years they were outclassed.[br]Principal Honours and DistinctionsFRS 1844.Bibliography1840, "On the locomotive engines of the London and Birmingham Railway", Transactions of the Institution of Civil Engineers 3 (4) (provides details of his locomotives and the thinking behind them).Further ReadingC.F.Dendy Marshall, 1953, A History of'Railway Locomotives Down to the End of the Year 1831, London: The Locomotive Publishing Co.

12 Dassault (Bloch), Marcel
SUBJECT AREA: Aerospace[br]b. 22 January 1892 Paris, Franced. 18 April 1986 Paris, France[br]French aircraft designer and manufacturer, best known for his jet fighters the Mystère and Mirage.[br]During the First World War, Marcel Bloch (he later changed his name to Dassault) worked on French military aircraft and developed a very successful propeller. With his associate, Henri Potez, he set up a company to produce their Eclair wooden propeller in a furniture workshop in Paris. In 1917 they produced a two-seater aircraft which was ordered but then cancelled when the war ended. Potez continued to built aircraft under his own name, but Bloch turned to property speculation, at which he was very successful. In 1930 Bloch returned to the aviation business with an unsuccessful bomber followed by several moderately effective airliners, including the Bloch 220 of 1935, which was similar to the DC-3. He was involved in the design of a four-engined airliner, the SNCASE Languedoc, which flew in September 1939. During the Second World War, Bloch and his brothers became important figures in the French Resistance Movement. Marcel Bloch was eventually captured but survived; however, one of his brothers was executed, and after the war Bloch changed his name to Dassault, which had been his brother's code name in the Resistance. During the 1950s, Avions Marcel Dassault rapidly grew to become Europe's foremost producer of jet fighters. The Ouragon was followed by the Mystère, Etendard and then the outstanding Mirage series. The basic delta-winged Mirage III, with a speed of Mach 2, was soon serving in twenty countries around the world. From this evolved a variable geometry version, a vertical-take-off aircraft, an enlarged light bomber capable of carrying a nuclear bomb, and a swept-wing version for the 1970s. Dassault also produced a successful series of jet airliners starting with the Fan Jet Falcon of 1963. When the Dassault and Breguet companies merged in 1971, Marcel Dassault was still a force to be reckoned with.[br]Principal Honours and DistinctionsGuggenheim Medal.

13 Houldsworth, Henry
SUBJECT AREA: Textiles[br]b. 1797 Manchester (?), Englandd. 1868 Manchester (?), England[br]English cotton spinner who introduced the differential gear to roving frames in Britain.[br]There are two claimants for the person who originated the differential gear as applied to roving frames: one is J.Green, a tinsmith of Mansfield, in his patent of 1823; the other is Arnold, who had applied it in America and patented it in early 1823. This latter was the source for Houldsworth's patent in 1826. It seems that Arnold's gearing was secretly communicated to Houldsworth by Charles Richmond, possibly when Houldsworth visited the United States in 1822–3, but more probably in 1825 when Richmond went to England. In return, Richmond received information about parts of a cylinder printing machine from Houldsworth. In the working of the roving frame, as the rovings were wound onto their bobbins and the diameter of the bobbins increased, the bobbin speed had to be reduced to keep the winding on at the same speed while the flyers and drawing rollers had to maintain their initial speed. Although this could be achieved by moving the driving belt along coned pulleys, this method did not provide enough power and slippage occurred. The differential gear combined the direct drive from the main shaft of the roving frame with that from the cone drive, so that only the latter provided the dif-ference between flyer and bobbin speeds, i.e. the winding speeds, thus taking away most of the power from that belt. Henry Houldsworth Senior (1774–1853) was living in Manchester when his son Henry was born, but by 1800 had moved to Glasgow. He built several mills, including a massive one at Anderston, Scotland, in which a Boulton \& Watt steam engine was installed. Henry Houldsworth Junior was probably back in Manchester by 1826, where he was to become an influential cotton spinner as chief partner in his mills, which he moved out to Reddish in 1863–5. He was also a prominent landowner in Cheetham. When William Fairbairn was considering establishing the Association for the Prevention of Steam Boiler Explosions in 1854, he wanted to find an influential manufacturer and mill-owner and he made a happy choice when he turned to Henry Houldsworth for assistance.[br]Bibliography1826, British patent no. 5,316 (differential gear for roving frames).Further ReadingDetails about Henry Houldsworth Junior are very sparse. The best account of his acquisition of the differential gear is given by D.J.Jeremy, 1981, Transatlantic Industrial Revolution.

14 Robinson, George J.
SUBJECT AREA: Textiles[br]b. 1712 Scotlandd. 1798 England[br]Scottish manufacturer who installed the first Boulton \& Watt rotative steam-engine in a textile mill.[br]George Robinson is said to have been a Scots migrant who settled at Burwell, near Nottingham, in 1737, but there is no record of his occupation until 1771, when he was noticed as a bleacher. By 1783 he and his son were describing themselves as "merchants and thread manufacturers" as well as bleachers. For their thread, they were using the system of spinning on the waterframe, but it is not known whether they held a licence from Arkwright. Between 1776 and 1791, the firm G.J. \& J.Robinson built a series of six cotton mills with a complex of dams and aqueducts to supply them in the relatively flat land of the Leen valley, near Papplewick, to the north of Nottingham. By careful conservation they were able to obtain considerable power from a very small stream. Castle mill was not only the highest one owned by the Robinsons, but it was also the highest mill on the stream and was fed from a reservoir. The Robinsons might therefore have expected to have enjoyed uninterrupted use of the water, but above them lived Lord Byron in his estate of Newstead Priory. The fifth Lord Byron loved making ornamental ponds on his property so that he could have mock naval battles with his servants, and this tampered with the water supplies so much that the Robinsons found they were unable to work their mills.In 1785 they decided to order a rotative steam engine from the firm of Boulton \& Watt. It was erected by John Rennie; however, misfortune seemed to dog this engine, for parts went astray to Manchester and when the engine was finally running at the end of February 1786 it was found to be out of alignment so may not have been very successful. At about the same time, the lawsuit against Lord Byron was found in favour of the Robinsons, but the engine continued in use for at least twelve years and was the first of the type which was to power virtually all steamdriven mills until the 1850s to be installed in a textile mill. It was a low-pressure double-acting condensing beam engine, with a vertical cylinder, parallel motion connecting the piston toone end of a rocking beam, and a connecting rod at the other end of the beam turning the flywheel. In this case Watt's sun and planet motion was used in place of a crank.[br]Further ReadingR.L.Hills, 1970, Power in the Industrial Revolution, Manchester (for an account of the installation of this engine).D.M.Smith, 1965, Industrial Archaeology of the East Midlands, Newton Abbot (describes the problems which the Robinsons had with the water supplies to power their mills).S.D.Chapman, 1967, The Early Factory Masters, Newton Abbot (provides details of the business activities of the Robinsons).J.D.Marshall, 1959, "Early application of steam power: the cotton mills of the Upper Leen", Transactions of the Thoroton Society of Nottinghamshire 60 (mentions the introduction of this steam-engine).RLH -
15 Voisin, Gabriel
SUBJECT AREA: Aerospace[br]b. 5 February 1880 Belleville-sur-Saône, Franced. 25 December 1973 Ozenay, France[br]French manufacturer of aeroplanes in the early years of aviation.[br]Gabriel Voisin was one of a group of aviation pioneers working in France c. 1905. One of the leaders of this group was a rich lawyer-sportsman, Ernest Archdeacon. For a number of years they had been building gliders based on those of the Wright brothers. Archdeacon's glider of 1904 was flown by Voisin, who went on to assist in the design and manufacture of gliders for Archdeacon and Louis Blériot, including successful float-gliders. Gabriel Voisin was joined by his brother Charles in 1905 and they set up the first commercial aircraft factory. As the Voisins had limited funds, they had to seek customers who could afford to indulge in the fashionable hobby of flying. One was Santos- Dumont, who commissioned Voisin to build his "14 bis" aeroplane in 1906.Early in 1907 the Voisins built their first powered aeroplane, but it was not a success.Later that year they completed a biplane for a Paris sculptor, Léon Delagrange, and another for Henri Farman. The basic Voisin was a biplane with the engine behind the pilot and a "pusher" propeller. Pitching was controlled by biplane elevators forward of the pilot and rudders were fitted to the box kite tail, but there was no control of roll.Improvements were gradually introduced by the Voisins and their customers, such as Farman. Incidentally, to flatter their clients the Voisins often named the aircraft after them, thus causing some confusion to historians. Many Voisins were built up until 1910, when the company's fortunes sank. Competition was growing, the factory was flooded, and Charles left. Gabriel started again, building robust biplanes of steel construction. Voisin bombers were widely used during the First World War, and a subsidiary factory was built in Russia.In August 1917, Voisin sold his business when the French Air Ministry decided that Voisin aeroplanes were obsolete and that the factory should be turned over to the building of engines. After the war he started another business making prefabricated houses, and then turned to manufacturing motor cars. From 1919 to 1939 his company produced various models, mainly for the luxury end of the market but also including a few sports and racing cars. In the early 1950s he designed a small two-seater, which was built by the Biscuter company in Spain. The Voisin company finally closed in 1958.[br]Principal Honours and DistinctionsChevalier de la Légion d'honneur 1909.

16 Whitney, Eli
[br]b. 8 December 1765 Westborough, Massachusetts, USAd. 8 January 1825 New Haven, Connecticut, USA[br]American inventor of the cotton gin and manufacturer of firearms.[br]The son of a prosperous farmer, Eli Whitney as a teenager showed more interest in mechanics than school work. At the age of 15 he began an enterprise business manufacturing nails in his father's workshop, even having to hire help to fulfil his orders. He later determined to acquire a university education and, his father having declined to provide funds, he taught at local schools to obtain the means to attend Leicester Academy, Massachusetts, in preparation for his entry to Yale in 1789. He graduated in 1792 and then decided to study law. He accepted a position in Georgia as a tutor that would have given him time for study; this post did not materialize, but on his journey south he met General Nathanael Greene's widow and the manager of her plantations, Phineas Miller (1764–1803). A feature of agriculture in the southern states was that the land was unsuitable for long-staple cotton but could yield large crops of green-seed cotton. Green-seed cotton was difficult to separate from its seed, and when Whitney learned of the problem in 1793 he quickly devised a machine known as the cotton gin, which provided an effective solution. He formed a partnership with Miller to manufacture the gin and in 1794 obtained a patent. This invention made possible the extraordinary growth of the cotton industry in the United States, but the patent was widely infringed and it was not until 1807, after amendment of the patent laws, that Whitney was able to obtain a favourable decision in the courts and some financial return.In 1798 Whitney was in financial difficulties following the failure of the initial legal action against infringement of the cotton gin patent, but in that year he obtained a government contract to supply 10,000 muskets within two years with generous advance payments. He built a factory at New Haven, Connecticut, and proposed to use a new method of manufacture, perhaps the first application of the system of interchangeable parts. He failed to supply the firearms in the specified time, and in fact the first 500 guns were not delivered until 1801 and the full contract was not completed until 1809.In 1812 Whitney made application for a renewal of his cotton gin patent, but this was refused. In the same year, however, he obtained a second contract from the Government for 15,000 firearms and a similar one from New York State which ensured the success of his business.[br]Further ReadingJ.Mirsky and A.Nevins, 1952, The World of Eli Whitney, New York (a good biography).

17 Wratten, Frederick Charles Luther
SUBJECT AREA: Photography, film and optics[br]b. 1840 Englandd. 8 April 1926 London, England[br]English inventor and manufacturer, founder of one of the first successful gelatine dry-plate companies.[br]He started his working life as a schoolteacher, but in his early twenties he moved to London to become a clerk with a photographic wholesaler, Soloman. There Wratten became interested in photography, and on the announcement of the new gelatine dry-plate processes he began to conduct his own experiments. In 1876 he devised a means of drying gelatine emulsions and removing excess silver with alcohol, and published details in 1877 and 1878. It was during this period that he formed a partnership with Henry Wainwright to manufacture and sell photographic materials. The mass production of gelatine dry plates was a British invention and monopoly, and the new firm of Wratten \& Wainwright was one of the first in the field and soon proved to be amongst the most successful. The business exported extensively to Europe, introducing a succession of plates of increasing sensitivity. Wratten continued to trade under the same name when his partner Wainwright died in 1882. His success continued, and in 1890 he moved the company to a newly equipped factory in Croydon, near London. Six years later Wratten incorporated as co-owners of the business his son, S.H.Wainwright and a young graduate from London University, C.E.Kenneth Mees. The newly constituted company soon introduced the first British panchromatic plates and filters. The introduction of Lumiere's Autochrome plates in 1907 prompted Wratten and Mees to take out a patent on a colour screen plate process of their own. The company also found work coating plates for other similar innovations. In 1912 the business was finally sold to George Eastman and Wratten and Mees joined Kodak Ltd at Harrow.[br]BibliographyWratten's early work on the action of alcohol on gelatine emulsions was described in a series of articles: 1877, Photographic News: 390, 49.1878, Photographic News: 121–3.1878, British Journal of Photography: 124–5.Further ReadingE.J.Wall, 1925, Three Colour Photography.C.E.K.Mees, 1961, From Dry Plates to Ektachrome Film, New York.JWBiographical history of technology > Wratten, Frederick Charles Luther
