8 Hunter, Matthew Albert
SUBJECT AREA: Metallurgy[br]b. 9 November 1878 Auckland Province, New Zealandd. 24 March 1961 Troy, New York, USA[br]New Zealand/American technologist and academic who was a pioneer in the production of metallic titanium.[br]Hunter arrived in England in 1902, the seventh in the succession of New Zealand students nominated for the 1851 Exhibition science research scholarships (the third, in 1894, having been Ernest Rutherford). He intended to study the metallurgy of tellurides at the Royal School of Mines, but owing to the death of the professor concerned, he went instead to University College London, where his research over two years involved the molecular aggregation of liquified gases. In 1904–5 he spent a third year in Göttingen, Paris and Karlsruhe. Hunter then moved to the USA, beginning work in 1906 with the General Electric Company in Schenectady. His experience with titanium came as part of a programme to try to discover satisfactory lamp-filament materials. He and his colleagues achieved more success in producing moderately pure titanium than previous workers had done, but found the metal's melting temperature inadequate. However, his research formed the basis for the "Hunter sodium process", a modern method for producing commercial quantities of titanium. In 1908 he was appointed Assistant Professor of Electrochemistry and Physics at Rensselaer Polytechnic Institute in Troy, New York, where he was to remain until his retirement in 1949 as Dean Emeritus. In the 1930s he founded and headed the Institute's Department of Metallurgical Engineering. As a consultant, he was associated with the development of Invar, Managanin and Constantan alloys.[br]Principal Honours and Distinctions1851 Great Exhibition science research scholar 1902–5.

10 Stanley, Robert Crooks
[br]b. 1 August 1876 Little Falls, New Jersey, USAd. 12 February 1951 USA[br]American mining engineer and metallurgist, originator of Monel Metal[br]Robert, the son of Thomas and Ada (Crooks) Stanley, helped to finance his early training at the Stevens Institute of Technology, Hoboken, New Jersey, by working as a manual training instructor at Montclair High School. After graduating in mechanical engineering from Stevens in 1899, and as a mining engineer from the Columbia School of Mines in 1901, he accepted a two-year assignment from the S.S.White Dental Company to investigate platinum-bearing alluvial deposits in British Columbia. This introduced him to the International Nickel Company (Inco), which had been established on 29 March 1902 to amalgamate the major mining companies working the newly discovered cupro-nickel deposits at Sudbury, Ontario. Ambrose Monell, President of Inco, appointed Stanley as Assistant Superintendent of its American Nickel Works at Camden, near Philadelphia, in 1903. At the beginning of 1904 Stanley was General Superintendent of the Orford Refinery at Bayonne, New Jersey, where most of the output of the Sudbury mines was treated.Copper and nickel were separated there from the bessemerized matte by the celebrated "tops and bottoms" process introduced thirteen years previously by R.M.Thompson. It soon occurred to Stanley that such a separation was not invariably required and that, by reducing directly the mixed matte, he could obtain a natural cupronickel alloy which would be ductile, corrosion resistant, and no more expensive to produce than pure copper or nickel. His first experiment, on 30 December 1904, was completely successful. A railway wagon full of bessemerized matte, low in iron, was calcined to oxide, reduced to metal with carbon, and finally desulphurized with magnesium. Ingots cast from this alloy were successfully forged to bars which contained 68 per cent nickel, 23 per cent copper and about 1 per cent iron. The new alloy, originally named after Ambrose Monell, was soon renamed Monel to satisfy trademark requirements. A total of 300,000 ft2 (27,870 m2) of this white, corrosion-resistant alloy was used to roof the Pennsylvania Railway Station in New York, and it also found extensive applications in marine work and chemical plant. Stanley greatly increased the output of the Orford Refinery during the First World War, and shortly after becoming President of the company in 1922, he established a new Research and Development Division headed initially by A.J.Wadham and then by Paul D. Merica, who at the US Bureau of Standards had first elucidated the mechanism of age-hardening in alloys. In the mid- 1920s a nickel-ore body of unprecedented size was identified at levels between 2,000 and 3,000 ft (600 and 900 m) below the Frood Mine in Ontario. This property was owned partially by Inco and partially by the Mond Nickel Company. Efficient exploitation required the combined economic resources of both companies. They merged on 1 January 1929, when Mond became part of International Nickel. Stanley remained President of the new company until February 1949 and was Chairman from 1937 until his death.[br]Principal Honours and DistinctionsAmerican Society for Metals Gold Medal.

11 Brearley, Harry
SUBJECT AREA: Metallurgy[br]b. 18 February 1871 Sheffield, Englandd. 14 July 1948 Torquay, Devon, England[br]English inventor of stainless steel.[br]Brearley was born in poor circumstances. He received little formal education and was nurtured rather in and around the works of Thomas Firth \& Sons, where his father worked in the crucible steel-melting shop. One of his first jobs was to help in their chemical laboratory where the chief chemist, James Taylor, encouraged him and helped him fit himself for a career as a steelworks chemist.In 1901 Brearley left Firth's to set up a laboratory at Kayser Ellison \& Co., but he returned to Firth's in 1904, when he was appointed Chief Chemist at their Riga works, and Works Manager the following year. In 1907 he returned to Sheffield to design and equip a research laboratory to serve both Firth's and John Brown \& Co. It was during his time as head of this laboratory that he made his celebrated discovery. In 1913, while seeking improved steels for rifle barrels, he used one containing 12.68 per cent chromium and 0.24 per cent carbon, in the hope that it would resist fouling and erosion. He tried to etch a specimen for microscopic examination but failed, from which he concluded that it would resist corrosion by, for example, the acids encountered in foods and cooking. The first knives made of this new steel were unsatisfactory and the 1914–18 war interrupted further research. But eventually the problems were overcome and Brearley's discovery led to a range of stainless steels with various compositions for domestic, medical and industrial uses, including the well-known "18–8" steel, with 18 per cent chromium and 8 per cent nickel.In 1915 Brearley left the laboratory to become Works Manager, then Technical Director, at Brown Bayley's steelworks until his retirement in 1925.[br]Principal Honours and DistinctionsIron and Steel Institute Bessemer Gold Medal 1920.BibliographyBrearley wrote several books, including: 1915 (?), with F.Ibbotson, The Analysis of Steelworks Materials, London.The Heat Treatment of Tool Steels. Ingots and Ingot Moulds.Later books include autobiographical details: 1946, Talks on Steelmaking, American Society for Metals.1941, Knotted String: Autobiography of a Steelmaker, London: Longmans, Green.Further ReadingObituary, 1948, Journal of the Iron and Steel Institute: 428–9.LRD -

16 Taylor, Frederick Winslow
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.

17 Perkins, Jacob
[br]b. 9 July 1766 Newburyport, Massachusetts, USAd. 30 July 1849 London, England[br]American inventor of a nail-making machine and a method of printing banknotes, investigator of the use of steam at very high pressures.[br]Perkins's occupation was that of a gold-and silversmith; while he does not seem to have followed this after 1800, however, it gave him the skills in working metals which he would continue to employ in his inventions. He had been working in America for four years before he patented his nail-making machine in 1796. At the time there was a great shortage of nails because only hand-forged ones were available. By 1800, other people had followed his example and produced automatic nail-making machines, but in 1811 Perkins' improved machines were introduced to England by J.C. Dyer. Eventually Perkins had twenty-one American patents for a range of inventions in his name.In 1799 Perkins invented a system of engraving steel plates for printing banknotes, which became the foundation of modern siderographic work. It discouraged forging and was adopted by many banking houses, including the Federal Government when the Second United States Bank was inaugurated in 1816. This led Perkins to move to Philadelphia. In the intervening years, Perkins had improved his nail-making machine, invented a machine for graining morocco leather in 1809, a fire-engine in 1812, a letter-lock for bank vaults and improved methods of rolling out spoons in 1813, and improved armament and equipment for naval ships from 1812 to 1815.It was in Philadelphia that Perkins became interested in the steam engine, when he met Oliver Evans, who had pioneered the use of high-pressure steam. He became a member of the American Philosophical Society and conducted experiments on the compressibility of water before a committee of that society. Perkins claimed to have liquified air during his experiments in 1822 and, if so, was the real discoverer of the liquification of gases. In 1819 he came to England to demonstrate his forgery-proof system of printing banknotes, but the Bank of England was the only one which did not adopt his system.While in London, Perkins began to experiment with the highest steam pressures used up to that time and in 1822 took out his first of nineteen British patents. This was followed by another in 1823 for a 10 hp (7.5 kW) engine with only 2 in. (51 mm) bore, 12 in. (305 mm) stroke but a pressure of 500 psi (35 kg/cm2), for which he claimed exceptional economy. After 1826, Perkins abandoned his drum boiler for iron tubes and steam pressures of 1,500 psi (105 kg/cm2), but the materials would not withstand such pressures or temperatures for long. It was in that same year that he patented a form of uniflow cylinder that was later taken up by L.J. Todd. One of his engines ran for five days, continuously pumping water at St Katherine's docks, but Perkins could not raise more finance to continue his experiments.In 1823 one his high-pressure hot-water systems was installed to heat the Duke of Wellington's house at Stratfield Saye and it acquired a considerable vogue, being used by Sir John Soane, among others. In 1834 Perkins patented a compression ice-making apparatus, but it did not succeed commercially because ice was imported more cheaply from Norway as ballast for sailing ships. Perkins was often dubbed "the American inventor" because his inquisitive personality allied to his inventive ingenuity enabled him to solve so many mechanical challenges.[br]Further ReadingHistorical Society of Pennsylvania, 1943, biography which appeared previously as a shortened version in the Transactions of the Newcomen Society 24.D.Bathe and G.Bathe, 1943–5, "The contribution of Jacob Perkins to science and engineering", Transactions of the Newcomen Society 24.D.S.L.Cardwell, 1971, From Watt to Clausius.

18 Haynes, Elwood
[br]b. 14 October 1857 Portland, Indiana, USAd. 13 April 1925 Kokomo, Indiana, USA[br]American inventor ofStellite cobalt-based alloys, early motor-car manufacturer and pioneer in stainless steels.[br]From his early years, Haynes was a practising Presbyterian and an active prohibitionist. He graduated in 1881 at Worcester, Massachusetts, and a spell of teaching in his home town was interrupted in 1884–5 while he attended the Johns Hopkins University in Baltimore. In 1886 he became permanently diverted by the discovery of natural gas in Portland. He was soon appointed Superintendent of the local gas undertaking, and then in 1890 he was hired by the Indiana Natural Gas \& Oil Company. While continuing his gas-company employment until 1901, Haynes conducted numerous metallurgical experiments. He also designed an automobile: this led to the establishment of the Haynes- Apperson Company at Kokomo as one of the earliest motor-car makers in North America. From 1905 the firm traded as the Haynes Automobile Company, and before its bankruptcy in 1924 it produced more than 50,000 cars. After 1905, Haynes found the first "Stellite" alloys of cobalt and chromium, and in 1910 he was publicizing the patented material. He then discovered the valuable hardening effect of tungsten, and in 1912 began applying the "improved" Stellite to cutting tools. Three years later, the Haynes Stellite Company was incorporated, with Haynes as President, to work the patents. It was largely from this source that Haynes became a millionaire in 1920. In April 1912, Haynes's attempt to patent the use of chromium with iron to render the product rustless was unsuccessful. However, he re-applied for a US patent on 12 March 1915 and, although this was initially rejected, he persevered and finally obtained recognition of his modified claim. The American Stainless Steel Company licensed the patents of Brearley and Haynes jointly in the USA until the 1930s.[br]Principal Honours and DistinctionsJohn Scott Medal 1919 (awarded for useful inventions).BibliographyHaynes was the author of more than twenty published papers and articles, among them: 1907, "Materials for automobiles", Proceedings of the American Society of MechanicalEngineers 29:1,597–606; 1910, "Alloys of nickel and cobalt with chromium", Journal of Industrial Engineeringand Chemistry 2:397–401; 1912–13, "Alloys of cobalt with chromium and other metals", Transactions of the American Institute of 'Mining Engineers 44:249–55;1919–20, "Stellite and stainless steel", Proceedings of the Engineering Society of WestPennsylvania 35:467–74.1 April 1919, US patent no. 1,299,404 (stainless steel).The four US patents worked by the Haynes Stellite Company were: 17 December 1907, patent no. 873,745.1 April 1913, patent no. 1,057,423.1 April 1913, patent no. 1,057, 828.17 August 1915, patent no. 1,150, 113.Further ReadingR.D.Gray, 1979, Alloys and Automobiles.

19 Herbert, Edward Geisler
[br]b. 23 March 1869 Dedham, near Colchester, Essex, Englandd. 9 February 1938 West Didsbury, Manchester, England[br]English engineer, inventor of the Rapidor saw and the Pendulum Hardness Tester, and pioneer of cutting tool research.[br]Edward Geisler Herbert was educated at Nottingham High School in 1876–87, and at University College, London, in 1887–90, graduating with a BSc in Physics in 1889 and remaining for a further year to take an engineering course. He began his career as a premium apprentice at the Nottingham works of Messrs James Hill \& Co, manufacturers of lace machinery. In 1892 he became a partner with Charles Richardson in the firm of Richardson \& Herbert, electrical engineers in Manchester, and when this partnership was dissolved in 1895 he carried on the business in his own name and began to produce machine tools. He remained as Managing Director of this firm, reconstituted in 1902 as a limited liability company styled Edward G.Herbert Ltd, until his retirement in 1928. He was joined by Charles Fletcher (1868–1930), who as joint Managing Director contributed greatly to the commercial success of the firm, which specialized in the manufacture of small machine tools and testing machinery.Around 1900 Herbert had discovered that hacksaw machines cut very much quicker when only a few teeth are in operation, and in 1902 he patented a machine which utilized this concept by automatically changing the angle of incidence of the blade as cutting proceeded. These saws were commercially successful, but by 1912, when his original patents were approaching expiry, Herbert and Fletcher began to develop improved methods of applying the rapid-saw concept. From this work the well-known Rapidor and Manchester saws emerged soon after the First World War. A file-testing machine invented by Herbert before the war made an autographic record of the life and performance of the file and brought him into close contact with the file and tool steel manufacturers of Sheffield. A tool-steel testing machine, working like a lathe, was introduced when high-speed steel had just come into general use, and Herbert became a prominent member of the Cutting Tools Research Committee of the Institution of Mechanical Engineers in 1919, carrying out many investigations for that body and compiling four of its Reports published between 1927 and 1933. He was the first to conceive the idea of the "tool-work" thermocouple which allowed cutting tool temperatures to be accurately measured. For this advance he was awarded the Thomas Hawksley Gold Medal of the Institution in 1926.His best-known invention was the Pendulum Hardness Tester, introduced in 1923. This used a spherical indentor, which was rolled over, rather than being pushed into, the surface being examined, by a small, heavy, inverted pendulum. The period of oscillation of this pendulum provided a sensitive measurement of the specimen's hardness. Following this work Herbert introduced his "Cloudburst" surface hardening process, in which hardened steel engineering components were bombarded by steel balls moving at random in all directions at very high velocities like gaseous molecules. This treatment superhardened the surface of the components, improved their resistance to abrasion, and revealed any surface defects. After bombardment the hardness of the superficially hardened layers increased slowly and spontaneously by a room-temperature ageing process. After his retirement in 1928 Herbert devoted himself to a detailed study of the influence of intense magnetic fields on the hardening of steels.Herbert was a member of several learned societies, including the Manchester Association of Engineers, the Institute of Metals, the American Society of Mechanical Engineers and the Institution of Mechanical Engineers. He retained a seat on the Board of his company from his retirement until the end of his life.[br]Principal Honours and DistinctionsManchester Association of Engineers Butterworth Gold Medal 1923.

20 Smith, Oberlin
[br]b. 22 March 1840 Cincinnati, Ohio, USAd. 18 July 1926[br]American mechanical engineer, pioneer in experiments with magnetic recording.[br]Of English descent, Smith embarked on an education in mechanical engineering, graduating from West Jersey Academy, Bridgeton, New Jersey, in 1859. In 1863 he established a machine shop in Bridgeton, New Jersey, that became the Ferracute Machine Company in 1877, eventually specializing in the manufacture of presses for metalworking. He seems to have subscribed to design principles considered modern even in the 1990s, "always giving attention to the development of artistic form in combination with simplicity, and with massive strength where required" (bibliographic reference below). He was successful in his business, and developed and patented a large number of mechanical constructions.Inspired by the advent of the phonograph of Edison, in 1878 Smith obtained the tin-foil mechanical phonograph, analysed its shortcomings and performed some experiments in magnetic recording. He filed a caveat in the US Patent Office in order to be protected while he "reduced the invention to practice". However, he did not follow this trail. When there was renewed interest in practical sound recording and reproduction in 1888 (the constructions of Berliner and Bell \& Tainter), Smith published an account of his experiments in the journal Electrical World. In a corrective letter three weeks later it is clear that he was aware of the physical requirements for the interaction between magnetic coil and magnetic medium, but his publications also indicate that he did not as such obtain reproduction of recorded sound.Smith did not try to develop magnetic recording, but he felt it imperative that he be given credit for conceiving the idea of it. When accounts of Valdemar Poulsen's work were published in 1900, Smith attempted to prove some rights in the invention in the US Patent Office, but to no avail.He was a highly respected member of both his community and engineering societies, and in later life became interested in the anti-slavery cause that had also been close to the heart of his parents, as well as in the YMCA movement and in women's suffrage.[br]BibliographyApart from numerous technical papers, he wrote the book Press Working of Metals, 1896. His accounts on the magnetic recording experiments were "Some possible forms of phonograph", Electrical World (8 September 1888): 161 ff, and "Letter to the Editor", Electrical World (29 September 1888): 179.Further ReadingF.K.Engel, 1990, Documents on the Invention of Magnetic Recording in 1878, New York: Audio Engineering Society, Reprint no. 2,914 (G2) (a good overview of the material collected by the Oberlin Smith Society, Bridgeton, New Jersey, in particular as regards the recording experiments; it is here that it is doubted that Valdemar Poulsen developed his ideas independently).GB-N
