4 Tesla, Nikola
SUBJECT AREA: Electricity[br]b. 9 July 1856 Smiljan, Croatiad. 7 January 1943 New York, USA[br]Serbian (naturalized American) engineer and inventor of polyphase electrical power systems.[br]While at the technical institute in Graz, Austria, Tesla's attention was drawn to the desirability of constructing a motor without a commutator. He considered the sparking between the commutator and brushes of the Gramme machine when run as a motor a serious defect. In 1881 he went to Budapest to work on the telegraph system and while there conceived the principle of the rotating magnetic field, upon which all polyphase induction motors are based. In 1882 Tesla moved to Paris and joined the Continental Edison Company. After building a prototype of his motor he emigrated to the United States in 1884, becoming an American citizen in 1889. He left Edison and founded an independent concern, the Tesla Electric Company, to develop his inventions.The importance of Tesla's first patents, granted in 1888 for alternating-current machines, cannot be over-emphasized. They covered a complete polyphase system including an alternator and induction motor. Other patents included the polyphase transformer, synchronous motor and the star connection of three-phase machines. These were to become the basis of the whole of the modern electric power industry. The Westinghouse company purchased the patents and marketed Tesla motors, obtaining in 1893 the contract for the Niagara Falls two-phase alternators driven by 5,000 hp (3,700 kW) water turbines.After a short period with Westinghouse, Tesla resigned to continue his research into high-frequency and high-voltage phenomena using the Tesla coil, an air-cored transformer. He lectured in America and Europe on his high-frequency devices, enjoying a considerable international reputation. The name "tesla" has been given to the SI unit of magnetic-flux density. The induction motor became one of the greatest advances in the industrial application of electricity. A claim for priority of invention of the induction motor was made by protagonists of Galileo Ferraris (1847–1897), whose discovery of rotating magnetic fields produced by alternating currents was made independently of Tesla's. Ferraris demonstrated the phenomenon but neglected its exploitation to produce a practical motor. Tesla himself failed to reap more than a small return on his work and later became more interested in scientific achievement than commercial success, with his patents being infringed on a wide scale.[br]Principal Honours and DistinctionsAmerican Institute of Electrical Engineers Edison Medal 1917.

5 Rawcliffe, Gordon Hindle
SUBJECT AREA: Electricity[br]b. 2 June 1910 Sheffield, Englandd. 3 September 1979 Bristol, England[br]English scientist and inventor of the multi-speed induction motor using the pole amplitude modulation principle.[br]After graduating from Keble College, Oxford, Rawcliffe joined the Metropolitan Vickers Electrical Company in 1932 as a college apprentice, and later became a design engineer. This was followed by a period as a lecturer at Liverpool University, where he was able to extend his knowledge of the principles underlying the design and operation of electrical machines. In 1941 he became Head of the Electrical Engineering Department at the Robert Gordon Technical College, Aberdeen, and Lecturer in charge of Electrical Engineering at Aberdeen University. In 1944 Rawcliffe was appointed to the Chair of Electrical Engineering at the University of Bristol, where he remained until his retirement in 1975. The reputation of his department was enhanced by the colleagues he recruited.After 1954 he began research into polyphase windings, the basis of alternating-current machinery, and published papers concerned with the dual problems of frequency changing and pole changing. The result of this research was the discovery in 1957 of a technique for making squirrel-cage induction motors run at more than one speed. By reversing current in one part of the winding, the pole distribution and number were changed, and with it the speed of rotation.Rawcliffe's name became synonymous with pole amplitude modulation, or PAM, the name given to this technique. Described by Rawcliffe as a new philosophy of windings, the technique led to a series of research papers, patents and licensing agreements in addition to consultancies to advise on application problems. Commercial exploitation of the new idea throughout Western Europe, the United Kingdom and the United States followed. In total he contributed twentyfive papers to the Proceedings of the Institution of Electrical Engineers and some sixty British patent applications were filed.[br]Principal Honours and DistinctionsFRS 1972.

6 Northrop, James H.
SUBJECT AREA: Textiles[br]fl. 1890s Keighley, Yorkshire, England[br]English-born American inventor of the first successful loom to change the shuttles automatically when the weft ran out.[br]Although attempts had been continuing since about 1840 to develop a loom on which the shuttles were changed automatically when the weft was exhausted, it was not until J.H.Northrop invented his cop-changer and patented it in the United States in 1894 that the automatic loom really became a serious competitor to the ordinary power loom. Northrop was born at Keighley in Yorkshire but emigrated to America, where he developed his loom. In about 1891 he appears to have been undecided whether to work on the shuttle-changing system or the copchanging system, for in that year he took out three patents, one of which was for a shuttle changer and the other two for cop-changers.A communication from W.F.Draper, Northrop's employer, was used in 1894 as a patent in Britain for a cop-or bobbin-changing automatic loom, which was in fact the Northrop loom. A further five patents for stop motions were taken out in 1895, and yet another in 1896. In one shuttle-box, a feeler was pushed through a hole in the side of the shuttle each time the shuttle entered the box. When the cop of weft was full, the loom carried on working normally. If lack of weft enabled the feeler to enter beyond a certain point, a device was activated which pushed a full cop down into the place of the old one. The full cops were contained in a rotary magazine, ready for insertion.The full Northrop loom comprised several basic inventions in addition to the cop-changer, namely a self-threading shuttle, a weft-fork mechanism to stop the loom, a warp let-off mechanism and a warp-stop motion. The Northrop loom revolutionized cotton weaving in America and the Northrop system became the basis for most later automatic looms. While Northrop looms were made in America and on the European continent, they never achieved much popularity in Britain, where finer cloth was usually woven.[br]Further ReadingW.A.Hanton, 1929, Automatic Weaving, London (describes the Northrop loom and has good illustrations of the mechanism).W.English, 1969, The Textile Industry, London (explains the Northrop system).

7 Singer, Isaac Merritt
[br]b. 27 October 1811 Pittstown, New York, USAd. 23 July 1875 Torquay, Devonshire, England[br]American inventor of a sewing machine, and pioneer of mass production.[br]The son of a millwright, Singer was employed as an unskilled labourer at the age of 12, but later gained wide experience as a travelling machinist. He also found employment as an actor. On 16 May 1839, while living at Lockport, Illinois, he obtained his first patent for a rock-drilling machine, but he soon squandered the money he made. Then in 1849, while at Pittsburgh, he secured a patent for a wood-and metal-carving machine that he had begun five years previously; however, a boiler explosion in the factory destroyed his machine and left him penniless.Near the end of 1850 Singer was engaged to redesign the Lerow \& Blodgett sewing machine at the Boston shop of Orson C.Phelps, where the machine was being repaired. He built an improved version in eleven days that was sufficiently different for him to patent on 12 August 1851. He formed a partnership with Phelps and G.B. Zieber and they began to market the invention. Singer soon purchased Phelps's interest, although Phelps continued to manufacture the machines. Then Edward Clark acquired a one-third interest and with Singer bought out Zieber. These two, with dark's flair for promotion and marketing, began to create a company which eventually would become the largest manufacturer of sewing machines exported worldwide, with subsidiary factories in England.However, first Singer had to defend his patent, which was challenged by an earlier Boston inventor, Elias Howe. Although after a long lawsuit Singer had to pay royalties, it was the Singer machine which eventually captured the market because it could do continuous stitching. In 1856 the Great Sewing Machine Combination, the first important pooling arrangement in American history, was formed to share the various patents so that machines could be built without infringements and manufacture could be expanded without fear of litigation. Singer contributed his monopoly on the needle-bar cam with his 1851 patent. He secured twenty additional patents, so that his original straight-needle vertical design for lock-stitching eventually included such refinements as a continuous wheel-feed, yielding presser-foot, and improved cam for moving the needle-bar. A new model, introduced in 1856, was the first to be intended solely for use in the home.Initially Phelps made all the machines for Singer. Then a works was established in New York where the parts were assembled by skilled workers through filing and fitting. Each machine was therefore a "one-off" but Singer machines were always advertised as the best on the market and sold at correspondingly high prices. Gradually, more specialized machine tools were acquired, but it was not until long after Singer had retired to Europe in 1863 that Clark made the change to mass production. Sales of machines numbered 810 in 1853 and 21,000 ten years later.[br]Bibliography12 August 1851, US patent no. 8,294 (sewing machine)Further ReadingBiographies and obituaries have appeared in Appleton's Cyclopedia of America, Vol. V; Dictionary of American Biography, Vol XVII; New York Times 25 July 1875; Scientific American (1875) 33; and National Cyclopaedia of American Biography.D.A.Hounshell, 1984, From the American System to Mass Production 1800–1932.

8 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.

9 Bacon, Francis Thomas
SUBJECT AREA: Aerospace[br]b. 21 December 1904 Billericay, Englandd. 24 May 1992 Little Shelford, Cambridge, England[br]English mechanical engineer, a pioneer in the modern phase of fuel-cell development.[br]After receiving his education at Eton and Trinity College, Cambridge, Bacon served with C.A. Parsons at Newcastle upon Tyne from 1925 to 1940. From 1946 to 1956 he carried out research on Hydrox fuel cells at Cambridge University and was a consultant on fuel-cell design to a number of organizations throughout the rest of his life.Sir William Grove was the first to observe that when oxygen and hydrogen were supplied to platinum electrodes immersed in sulphuric acid a current was produced in an external circuit, but he did not envisage this as a practical source of electrical energy. In the 1930s Bacon started work to develop a hydrogen-oxygen fuel cell that operated at moderate temperatures and pressures using an alkaline electrolyte. In 1940 he was appointed to a post at King's College, London, and there, with the support of the Admiralty, he started full-time experimental work on fuel cells. His brief was to produce a power source for the propulsion of submarines. The following year he was posted as a temporary experimental officer to the Anti-Submarine Experimental Establishment at Fairlie, Ayrshire, and he remained there until the end of the Second World War.In 1946 he joined the Department of Chemical Engineering at Cambridge, receiving a small amount of money from the Electrical Research Association. Backing came six years later from the National Research and Development Corporation (NRDC), the development of the fuel cell being transferred to Marshalls of Cambridge, where Bacon was appointed Consultant.By 1959, after almost twenty years of individual effort, he was able to demonstrate a 6 kW (8 hp) power unit capable of driving a small truck. Bacon appreciated that when substantial power was required over long periods the hydrogen-oxygen fuel cell associated with high-pressure gas storage would be more compact than conventional secondary batteries.The development of the fuel-cell system pioneered by Bacon was stimulated by a particular need for a compact, lightweight source of power in the United States space programme. Electro-chemical generators using hydrogen-oxygen cells were chosen to provide the main supplies on the Apollo spacecraft for landing on the surface of the moon in 1969. An added advantage of the cells was that they simultaneously provided water. NRDC was largely responsible for the forma-tion of Energy Conversion Ltd, a company that was set up to exploit Bacon's patents and to manufacture fuel cells, and which was supported by British Ropes Ltd, British Petroleum and Guest, Keen \& Nettlefold Ltd at Basingstoke. Bacon was their full-time consultant. In 1971 Energy Conversion's operation was moved to the UK Atomic Energy Research Establishment at Harwell, as Fuel Cells Ltd. Bacon remained with them until he retired in 1973.[br]Principal Honours and DistinctionsOBE 1967. FRS 1972. Royal Society S.G. Brown Medal 1965.

SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 13 January 1847 Memmingen, Bavaria, Germanyd. 27 August 1932 Moylan, Pennsylvania, USA[br]German (naturalized American) mechanical engineer, inventor of bevel-gear generator and economist.[br]Hugo Bilgram studied mechanical engineering at the Augsburg Maschinenbau Schule and graduated in 1865. He worked as a machinist and draughtsman for several firms in Germany before going to the United States in 1869.In America he first worked for L.B.Flanders Company and Southwark Foundry \& Machine Company in Philadelphia, designing instruments and machines. In the 1870s he also assisted in an evening class in drawing at The Franklin Institute. He devised the Bilgram Valve Diagram for analysing the action of steam engine slide valves and he developed a method of drawing accurate outlines of gear teeth. This led him to design a machine for cutting the teeth of gear wheels, particularly bevel wheels, which he patented in 1884. He was in charge of the American branch of Brehmer Brothers Company from 1879 and in 1884 became the sole owner of the company, which was later incorporated as the Bilgram Machine Works. He was responsible for several other inventions and developments in gear manufacture.Bilgram was a member of the Franklin Institute, the American Academy of Political and Social Science, the Philadelphia Technische Verein and the Philadelphia Engineer's Club, and was elected a member of the American Society of Mechanical Engineers in 1885. He was also an amateur botanist, keenly interested in microscopic work.[br]Principal Honours and DistinctionsFranklin Institute Elliott Cresson Gold Medal.

11 Howe, Frederick Webster
[br]b. 28 August 1822 Danvers, Massachusetts, USAd. 25 April 1891 Providence, Rhode Island, USA[br]American mechanical engineer, machine-tool designer and inventor.[br]Frederick W.Howe attended local schools until the age of 16 and then entered the machine shop of Gay \& Silver at North Chelmsford, Massachusetts, as an apprentice and remained with that firm for nine years. He then joined Robbins, Kendall \& Lawrence of Windsor, Vermont, as Assistant to Richard S. Lawrence in designing machine tools. A year later (1848) he was made Plant Superintendent. During his time with this firm, Howe designed a profiling machine which was used in all gun shops in the United States: a barrel-drilling and rifling machine, and the first commercially successful milling machine. Robbins \& Lawrence took to the Great Exhibition of 1851 in London, England, a set of rifles built on the interchangeable system. The interest this created resulted in a visit of some members of the British Royal Small Arms Commission to America and subsequently in an order for 150 machine tools, jigs and fixtures from Robbins \& Lawrence, to be installed at the small-arms factory at Enfield. From 1853 to 1856 Howe was in charge of the design and building of these machines. In 1856 he established his own armoury at Newark, New Jersey, but transferred after two years to Middletown, Connecticut, where he continued the manufacture of small arms until the outbreak of the Civil War. He then became Superintendent of the armoury of the Providence Tool Company at Providence, Rhode Island, and served in that capacity until the end of the war. In 1865 he went to Bridgeport, Connecticut, to assist Elias Howe with the manufacture of his sewing machine. After the death of Elias Howe, Frederick Howe returned to Providence to join the Brown \& Sharpe Manufacturing Company. As Superintendent of that establishment he worked with Joseph R. Brown in the development of many of the firm's products, including machinery for the Wilcox \& Gibbs sewing machine then being made by Brown \& Sharpe. From 1876 Howe was in business on his own account as a consulting mechanical engineer and in his later years he was engaged in the development of shoe machinery and in designing a one-finger typewriter, which, however, was never completed. He was granted several patents, mainly in the fields of machine tools and firearms. As a designer, Howe was said to have been a perfectionist, making frequent improvements; when completed, his designs were always sound.[br]Further ReadingJ.W.Roe, 1916, English and American Tool Builders, New Haven; repub. 1926, New York, and 1987, Bradley, 111.

12 Page, Charles Grafton
[br]b. 25 January 1812 Salem, Massachusetts, USAd. 5 May 1868 Washington, DC, USA[br]American scientist and inventor of electric motors.[br]Page graduated from Harvard in 1832 and subsequently attended Boston Medical School. He began to practise in Salem and also engaged in experimental research in electricity, discovering the improvement effected by substituting bundles of iron wire for solid bars in induction coils. He also created a device which he termed a Dynamic Multiplier, the prototype of the auto-transformer. Following a period in medical practice in Virginia, in 1841 he became one of the first two principal examiners in the United States Patent Office. He also held the Chair of Chemistry and Pharmacy at Columbian College, later George Washington University, between 1844 and 1849.A prolific inventor, Page completed several large electric motors in which reciprocating action was converted to rotary motion, and invested an extravagant sum of public money in a foredoomed effort to develop a 10-ton electric locomotive powered by primary batteries. This was unsuccessfully demonstrated in April 1851 on the Washington-Baltimore railway and seriously damaged his reputation. Page approached Thomas Davenport with an offer of partnership, but Davenport refused.After leaving the Patent Office in 1852 he became a patentee himself and advocated the reform of the patent procedures. Page returned to the Patent Office in 1861, and later persuaded Congress to pass a special Act permitting him to patent the induction coil. This was the cause, after his death, of protracted and widely publicized litigation.[br]Bibliography1867, History of Induction: The American Claim to the Induction Coil and itsElectrostatic Developments, Washington, DC.Further ReadingR.C.Post, 1976, Physics, Patents and Politics, New York (a biography which treats Page as a focal point for studying the American patent system).——1976, "Stray sparks from the induction coil: the Volta prize and the Page patent", Proceedings of the Institute of Electrical Engineers 64: 1,279–86 (a short account).W.J.King, 1962, The Development of Electrical Technology in the 19th Century, Washington, DC: Smithsonian Institution, Paper 28.GW -
13 Sickels, Frederick Ellsworth
[br]b. 20 September 1819 Gloucester County, New Jersey, USAd. 8 March 1895 Kansas City, Missouri, USA[br]American inventor of a steam-inlet cut-off valve mechanism for engines and steam steering apparatus for ships.[br]Sickels was educated in New York City, where his father was a practising physician. As he showed mechanical aptitude, at the age of 16 he joined the Harlem Railroad as a rod man, and a year later became a machinist in the Allaire Works in New York, studying physics and mechanics in his spare time. He perfected his cut-off mechanism for drop valves in 1841 and patented it the following year. The liberating mechanism allowed the valve to fall quickly onto its seat and so eliminated "wire-drawing" of the steam, and Sickels arranged a dashpot to prevent the valve hitting the seat violently. Through further improvements patented in 1843 and 1845, he gained a considerable fortune, but he subsequently lost it through fighting patent infringements because his valve gear was copied extensively.In 1846 he turned his attention to using a steam engine to assist the steering in ships. He filed a patent application in 1849 and completed a machine in 1854, but he could not find any ship owner willing to try it until 1858, when it was fitted to the August. A patent was granted in 1860, but as no American ship owners showed interest Sickels went to England, where he obtained three British patents; once again, however, he found no interest. He returned to the United States in 1867 and continued his fruitless efforts until he was financially ruined. He patented improved compound engines in 1875 and also contributed improvements in sinking pneumatic piles. He turned to civil engineering and engaged in railway and bridge construction in the west. In about 1890 he was made Consulting Engineer to the National Water Works Company of New York and in 1891 became Chief Engineer of its operations at Kansas City.[br]Further ReadingDictionary of American Biography, 1935, Vol. XVII, New York: C.Scribner's Sons.

14 Stumpf, Johann
SUBJECT AREA: Steam and internal combustion engines[br]fl. c. 1900 Germany[br]German inventor of a successful design of uniflow steam engine.[br]In 1869 Stumpf was commissioned by the Pope Manufacturing Company of Hertford, Connecticut, to set up two triple-expansion, vertical, Corliss pumping engines. He tried to simplify this complicated system and started research with the internal combustion engine and the steam turbine particularly as his models. The construction of steam turbines in several stages where the steam passed through in a unidirectional flow was being pursued at that time, and Stumpf wondered whether it would be possible to raise the efficiency of a reciprocating steam engine to the same thermal level as the turbine by the use of the uniflow principle.Stumpf began to investigate these principles without studying the work of earlier pioneers like L.J. Todd, which he later thought would have led him astray. It was not until 1908, when he was Professor at the Institute of Technology in Berlin- Charlottenburg, that he patented his successful "una-flow" steam engine. In that year he took out six British patents for improvements in details on his original one Stumpf fully realized the thermal advantages of compressing the residual steam and was able to evolve systems of coping with excessive compression when starting. He also placed steam-jackets around the ends of the cylinder. Stumpf's first engine was built in 1908 by the Erste B runner Maschinenfabrik-Gesellschaft, and licences were taken out by many other manufacturers, including those in Britain and the USA. His engine was developed into the most economical type of reciprocating steam engine.[br]Bibliography1912, The Una-Flow Steam Engine, Munich: R.

SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 20 March 1856 Germantown, Pennsylvania, USAd. 21 March 1915 Philadelphia, Pennsylvania, USA[br]American mechanical engineer and pioneer of scientific management.[br]Frederick W.Taylor received his early education from his mother, followed by some years of schooling in France and Germany. Then in 1872 he entered Phillips Exeter Academy, New Hampshire, to prepare for Harvard Law School, as it was intended that he should follow his father's profession. However, in 1874 he had to abandon his studies because of poor eyesight, and he began an apprenticeship at a pump-manufacturing works in Philadelphia learning the trades of pattern-maker and machinist. On its completion in 1878 he joined the Midvale Steel Company, at first as a labourer but then as Shop Clerk and Foreman, finally becoming Chief Engineer in 1884. At the same time he was able to resume study in the evenings at the Stevens Institute of Technology, and in 1883 he obtained the degree of Mechanical Engineer (ME). He also found time to take part in amateur sport and in 1881 he won the tennis doubles championship of the United States.It was while with the Midvale Steel Company that Taylor began the systematic study of workshop management, and the application of his techniques produced significant increases in the company's output and productivity. In 1890 he became Manager of a company operating large paper mills in Maine and Wisconsin, until 1893 when he set up on his own account as a consulting engineer specializing in management organization. In 1898 he was retained exclusively by the Bethlehem Steel Company, and there continued his work on the metal-cutting process that he had started at Midvale. In collaboration with J.Maunsel White (1856–1912) he developed high-speed tool steels and their heat treatment which increased cutting capacity by up to 300 per cent. He resigned from the Bethlehem Steel Company in 1901 and devoted the remainder of his life to expounding the principles of scientific management which became known as "Taylorism". The Society to Promote the Science of Management was established in 1911, renamed the Taylor Society after his death. He was an active member of the American Society of Mechanical Engineers and was its President in 1906; his presidential address "On the Art of Cutting Metals" was reprinted in book form.[br]Principal Honours and DistinctionsParis Exposition Gold Medal 1900.

SUBJECT AREA: Electricity[br]b. 9 May 1850 Oswestry, Englandd. 20 August 1936 Montclair, New Jersey, USA[br]English (naturalized American) inventor noted for his contribution to the technology of electrical measurements.[br]Although he developed dynamos for electroplating and lighting, Weston's major contribution to technology was his invention of a moving-coil voltmeter and the standard cell which bears his name. After some years as a medical student, during which he gained a knowledge of chemistry, he abandoned his studies. Emigrating to New York in 1870, he was employed by a manufacturer of photographic chemicals. There followed a period with an electroplating company during which he built his first dynamo. In 1877 some business associates financed a company to build these machines and, later, arc-lighting equipment. By 1882 the Weston Company had been absorbed into the United States Electric Lighting Company, which had a counterpart in Britain, the Maxim Weston Company. By the time Weston resigned from the company, in 1886, he had been granted 186 patents. He then began the work in which he made his greatest contribution, the science of electrical measurement.The Weston meter, the first successful portable measuring instrument with a pivoted coil, was made in 1886. By careful arrangement of the magnet, coil and control springs, he achieved a design with a well-damped movement, which retained its calibration. These instruments were produced commercially on a large scale and the moving-coil principle was soon adopted by many manufacturers. In 1892 he invented manganin, an alloy with a small negative temperature coefficient, for use as resistances in his voltmeters.The Weston standard cell was invented in 1892. Using his chemical knowledge he produced a cell, based on mercury and cadmium, which replaced the Clark cell as a voltage reference source. The Weston cell became the recognized standard at the International Conference on Electrical Units and Standards held in London in 1908.[br]Principal Honours and DistinctionsPresident, AIEE 1888–9.

17 Whitworth, Sir Joseph
[br]b. 21 December 1803 Stockport, Cheshire, Englandd. 22 January 1887 Monte Carlo, Monaco[br]English mechanical engineer and pioneer of precision measurement.[br]Joseph Whitworth received his early education in a school kept by his father, but from the age of 12 he attended a school near Leeds. At 14 he joined his uncle's mill near Ambergate, Derbyshire, to learn the business of cotton spinning. In the four years he spent there he realized that he was more interested in the machinery than in managing a cotton mill. In 1821 he obtained employment as a mechanic with Crighton \& Co., Manchester. In 1825 he moved to London and worked for Henry Maudslay and later for the Holtzapffels and Joseph Clement. After these years spent gaining experience, he returned to Manchester in 1833 and set up in a small workshop under a sign "Joseph Whitworth, Tool Maker, from London".The business expanded steadily and the firm made machine tools of all types and other engineering products including steam engines. From 1834 Whitworth obtained many patents in the fields of machine tools, textile and knitting machinery and road-sweeping machines. By 1851 the company was generally regarded as the leading manufacturer of machine tools in the country. Whitworth was a pioneer of precise measurement and demonstrated the fundamental mode of producing a true plane by making surface plates in sets of three. He advocated the use of the decimal system and made use of limit gauges, and he established a standard screw thread which was adopted as the national standard. In 1853 Whitworth visited America as a member of a Royal Commission and reported on American industry. At the time of the Crimean War in 1854 he was asked to provide machinery for manufacturing rifles and this led him to design an improved rifle of his own. Although tests in 1857 showed this to be much superior to all others, it was not adopted by the War Office. Whitworth's experiments with small arms led on to the construction of big guns and projectiles. To improve the quality of the steel used for these guns, he subjected the molten metal to pressure during its solidification, this fluid-compressed steel being then known as "Whitworth steel".In 1868 Whitworth established thirty annual scholarships for engineering students. After his death his executors permanently endowed the Whitworth Scholarships and distributed his estate of nearly half a million pounds to various educational and charitable institutions. Whitworth was elected an Associate of the Institution of Civil Engineers in 1841 and a Member in 1848 and served on its Council for many years. He was elected a Member of the Institution of Mechanical Engineers in 1847, the year of its foundation.[br]Principal Honours and DistinctionsBaronet 1869. FRS 1857.
