23 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.

24 Agricola, Georgius (Georg Bauer)
SUBJECT AREA: Metallurgy[br]b. 24 March 1494 Glauchau, Saxonyd. 21 November 1555 Chemnitz, Germany[br]German metallurgist, who wrote the book De Re Metallica under the latinized version of his name.[br]Agricola was a physician, scientist and metallurgist of note and it was this which led to the publication of De Re Metallica. He studied at Leipzig University and between 1518 and 1522 he was a school teacher in Zwickau. Eventually he settled as a physician in Chemnitz. Later he continued his medical practice at Joachimstal in the Erzgebirge. This town was newly built to serve the mining community in what was at the time the most important ore-mining field in both Germany and Europe.As a physician in the sixteenth century he would naturally have been concerned with the development of medicines, which would have led him to research the medical properties of ores and base metals. He studied the mineralogy of his area, and the mines, and the miners who were working there. He wrote several books in Latin on geology and mineralogy. His important work during that period was a glossary of mineralogical and mining terms in both Latin and German. It is, however, De Re Metallica for which he is best known. This large volume contains twelve books which deal with mining and metallurgy, including an account of glassmaking. Whilst one can understand the text of this book very easily, the quality of the illustrative woodcuts should not be neglected. These illustrations detail the mines, furnaces, forges and the plant associated with them, unfortunately the name of the artist is unknown. The importance of the work lies in the fact that it is an assemblage of information on all the methods and practices current at that time. The book was clearly intended as a textbook of mining and mineralogy and as such it would have been brought to England by German engineers when they were employed by the Mines Royal in the Keswick area in the late sixteenth century. In addition to his studies in preparation for De Re Metallica, Agricola was an "adventurer" holding shares in the Gottesgab mine in the Erzegebirge.[br]Principal Honours and Distinctions Bibliography1556, De Re Metallica, Basel; 1912, trans.

25 Armstrong, Sir William George, Baron Armstrong of Cragside
[br]b. 26 November 1810 Shieldfield, Newcastle upon Tyne, Englandd. 27 December 1900 Cragside, Northumbria, England[br]English inventor, engineer and entrepreneur in hydraulic engineering, shipbuilding and the production of artillery.[br]The only son of a corn merchant, Alderman William Armstrong, he was educated at private schools in Newcastle and at Bishop Auckland Grammar School. He then became an articled clerk in the office of Armorer Donkin, a solicitor and a friend of his father. During a fishing trip he saw a water-wheel driven by an open stream to work a marble-cutting machine. He felt that its efficiency would be improved by introducing the water to the wheel in a pipe. He developed an interest in hydraulics and in electricity, and became a popular lecturer on these subjects. From 1838 he became friendly with Henry Watson of the High Bridge Works, Newcastle, and for six years he visited the Works almost daily, studying turret clocks, telescopes, papermaking machinery, surveying instruments and other equipment being produced. There he had built his first hydraulic machine, which generated 5 hp when run off the Newcastle town water-mains. He then designed and made a working model of a hydraulic crane, but it created little interest. In 1845, after he had served this rather unconventional apprenticeship at High Bridge Works, he was appointed Secretary of the newly formed Whittle Dene Water Company. The same year he proposed to the town council of Newcastle the conversion of one of the quayside cranes to his hydraulic operation which, if successful, should also be applied to a further four cranes. This was done by the Newcastle Cranage Company at High Bridge Works. In 1847 he gave up law and formed W.G.Armstrong \& Co. to manufacture hydraulic machinery in a works at Elswick. Orders for cranes, hoists, dock gates and bridges were obtained from mines; docks and railways.Early in the Crimean War, the War Office asked him to design and make submarine mines to blow up ships that were sunk by the Russians to block the entrance to Sevastopol harbour. The mines were never used, but this set him thinking about military affairs and brought him many useful contacts at the War Office. Learning that two eighteen-pounder British guns had silenced a whole Russian battery but were too heavy to move over rough ground, he carried out a thorough investigation and proposed light field guns with rifled barrels to fire elongated lead projectiles rather than cast-iron balls. He delivered his first gun in 1855; it was built of a steel core and wound-iron wire jacket. The barrel was multi-grooved and the gun weighed a quarter of a ton and could fire a 3 lb (1.4 kg) projectile. This was considered too light and was sent back to the factory to be rebored to take a 5 lb (2.3 kg) shot. The gun was a complete success and Armstrong was then asked to design and produce an equally successful eighteen-pounder. In 1859 he was appointed Engineer of Rifled Ordnance and was knighted. However, there was considerable opposition from the notably conservative officers of the Army who resented the intrusion of this civilian engineer in their affairs. In 1862, contracts with the Elswick Ordnance Company were terminated, and the Government rejected breech-loading and went back to muzzle-loading. Armstrong resigned and concentrated on foreign sales, which were successful worldwide.The search for a suitable proving ground for a 12-ton gun led to an interest in shipbuilding at Elswick from 1868. This necessitated the replacement of an earlier stone bridge with the hydraulically operated Tyne Swing Bridge, which weighed some 1450 tons and allowed a clear passage for shipping. Hydraulic equipment on warships became more complex and increasing quantities of it were made at the Elswick works, which also flourished with the reintroduction of the breech-loader in 1878. In 1884 an open-hearth acid steelworks was added to the Elswick facilities. In 1897 the firm merged with Sir Joseph Whitworth \& Co. to become Sir W.G.Armstrong Whitworth \& Co. After Armstrong's death a further merger with Vickers Ltd formed Vickers Armstrong Ltd.In 1879 Armstrong took a great interest in Joseph Swan's invention of the incandescent electric light-bulb. He was one of those who formed the Swan Electric Light Company, opening a factory at South Benwell to make the bulbs. At Cragside, his mansion at Roth bury, he installed a water turbine and generator, making it one of the first houses in England to be lit by electricity.Armstrong was a noted philanthropist, building houses for his workforce, and endowing schools, hospitals and parks. His last act of charity was to purchase Bamburgh Castle, Northumbria, in 1894, intending to turn it into a hospital or a convalescent home, but he did not live long enough to complete the work.[br]Principal Honours and DistinctionsKnighted 1859.

26 Blackett, William Cuthbert
SUBJECT AREA: Mining and extraction technology[br]b. 18 November 1859 Durham, Englandd. 13 June 1935 Durham, England[br]English mine manager, expert in preventing mine explosions and inventor of a coal-face conveyor.[br]After leaving Durham college of Physical Science and having been apprenticed in different mines, he received the certificate for colliery managers and subsequently, in 1887, was appointed Manager of all the mines of Charlaw and Sacriston collieries in Durham. He remained in this position for the rest of his working life.Frequent explosions in mines led him to investigate the causes. He was among the first to recognize the role contributed by coal-dust on mine roads, pioneered the use of inert rock-or stone-dust to render the coal-dust harmless and was the originator of many technical terms on the subject. He contributed many papers on explosion and was appointed a member of many advisory committees on prevention measures. A liquid-air rescue apparatus, designed by him and patented in 1910, was installed in various parts of the country.Blackett also developed various new devices in mining machinery. He patented a wire-rope socket which made use of a metal wedge; invented a rotary tippler driven by frictional contact instead of gearing and which stopped automatically; and he designed a revolving cylindrical coal-washer, which also gained interest among German mining engineers. His most important invention, the first successful coal-face conveyor, was patented in 1902. It was driven by compressed air and consisted of a trough running along the length of the race through which ran an endless scraper chain. Thus fillers cast the coal into the trough, and the scraper chain drew it to the main gate to be loaded into trams.[br]Principal Honours and DistinctionsKnight of Grace of the Order of St John of Jerusalem.

27 Le Chatelier, Henri Louis
SUBJECT AREA: Metallurgy[br]b. 8 November 1850 Paris, Franced. 17 September 1926 Miribel-les-Echelle, France[br]French inventor of the rhodium—platinum thermocouple and the first practical optical pyrometer, and pioneer of physical metallurgy.[br]The son of a distinguished engineer, Le Chatelier entered the Ecole Polytechnique in 1869: after graduating in the Faculty of Mines, he was appointed Professor at the Ecole Supérieure des Mines in 1877. After assisting Deville with the purification of bauxite in unsuccessful attempts to obtain aluminium in useful quantities, Le Chatelier's work covered a wide range of topics and he gave much attention to the driving forces of chemical reactions. Between 1879 and 1882 he studied the mechanisms of explosions in mines, and his doctorate in 1882 was concerned with the chemistry and properties of hydraulic cements. The dehydration of such materials was studied by thermal analysis and dilatometry. Accurate temperature measurement was crucial and his work on the stability of thermocouples, begun in 1886, soon established the superiority of rhodium-platinum alloys for high-temperature measurement. The most stable combination, pure platinum coupled with a 10 per cent rhodium platinum positive limb, became known as Le Chatelier couple and was in general use throughout the industrial world until c. 1922. For applications where thermocouples could not be used, Le Chatelier also developed the first practical optical pyrometer. From hydraulic cements he moved on to refractory and other ceramic materials which were also studied by thermal analysis and dilatometry. By 1888 he was systematically applying such techniques to metals and alloys. Le Chatelier, together with Osmond, Worth, Genet and Charpy, was a leading member of that group of French investigators who established the new science of physical metallurgy between 1888 and 1900. Le Chatelier was determining the recalescence points in steels in 1888 and was among the first to study intermetallic compounds in a systematic manner. To facilitate such work he introduced the inverted microscope, upon which metallographers still depend for the routine examination of polished and etched metallurgical specimens under incident light. The principle of mobile equilibrium, developed independently by Le Chatelier in 1885 and F.Braun in 1886, stated that if one parameter in an equilibrium situation changed, the equilibrium point of the system would move in a direction which tended to reduce the effect of this change. This provided a useful qualitative working tool for the experimentalists, and was soon used with great effect by Haber in his work on the synthesis of ammonia.[br]Principal Honours and DistinctionsGrand Officier de la Légion d'honneur.

28 Trevithick, Richard
[br]b. 13 April 1771 Illogan, Cornwall, Englandd. 22 April 1833 Dartford, Kent, England[br]English engineer, pioneer of non-condensing steam-engines; designed and built the first locomotives.[br]Trevithick's father was a tin-mine manager, and Trevithick himself, after limited formal education, developed his immense engineering talent among local mining machinery and steam-engines and found employment as a mining engineer. Tall, strong and high-spirited, he was the eternal optimist.About 1797 it occurred to him that the separate condenser patent of James Watt could be avoided by employing "strong steam", that is steam at pressures substantially greater than atmospheric, to drive steam-engines: after use, steam could be exhausted to the atmosphere and the condenser eliminated. His first winding engine on this principle came into use in 1799, and subsequently such engines were widely used. To produce high-pressure steam, a stronger boiler was needed than the boilers then in use, in which the pressure vessel was mounted upon masonry above the fire: Trevithick designed the cylindrical boiler, with furnace tube within, from which the Cornish and later the Lancashire boilers evolved.Simultaneously he realized that high-pressure steam enabled a compact steam-engine/boiler unit to be built: typically, the Trevithick engine comprised a cylindrical boiler with return firetube, and a cylinder recessed into the boiler. No beam intervened between connecting rod and crank. A master patent was taken out.Such an engine was well suited to driving vehicles. Trevithick built his first steam-carriage in 1801, but after a few days' use it overturned on a rough Cornish road and was damaged beyond repair by fire. Nevertheless, it had been the first self-propelled vehicle successfully to carry passengers. His second steam-carriage was driven about the streets of London in 1803, even more successfully; however, it aroused no commercial interest. Meanwhile the Coalbrookdale Company had started to build a locomotive incorporating a Trevithick engine for its tramroads, though little is known of the outcome; however, Samuel Homfray's ironworks at Penydarren, South Wales, was already building engines to Trevithick's design, and in 1804 Trevithick built one there as a locomotive for the Penydarren Tramroad. In this, and in the London steam-carriage, exhaust steam was turned up the chimney to draw the fire. On 21 February the locomotive hauled five wagons with 10 tons of iron and seventy men for 9 miles (14 km): it was the first successful railway locomotive.Again, there was no commercial interest, although Trevithick now had nearly fifty stationary engines completed or being built to his design under licence. He experimented with one to power a barge on the Severn and used one to power a dredger on the Thames. He became Engineer to a project to drive a tunnel beneath the Thames at Rotherhithe and was only narrowly defeated, by quicksands. Trevithick then set up, in 1808, a circular tramroad track in London and upon it demonstrated to the admission-fee-paying public the locomotive Catch me who can, built to his design by John Hazledine and J.U. Rastrick.In 1809, by which date Trevithick had sold all his interest in the steam-engine patent, he and Robert Dickinson, in partnership, obtained a patent for iron tanks to hold liquid cargo in ships, replacing the wooden casks then used, and started to manufacture them. In 1810, however, he was taken seriously ill with typhus for six months and had to return to Cornwall, and early in 1811 the partners were bankrupt; Trevithick was discharged from bankruptcy only in 1814.In the meantime he continued as a steam engineer and produced a single-acting steam engine in which the cut-off could be varied to work the engine expansively by way of a three-way cock actuated by a cam. Then, in 1813, Trevithick was approached by a representative of a company set up to drain the rich but flooded silver-mines at Cerro de Pasco, Peru, at an altitude of 14,000 ft (4,300 m). Low-pressure steam engines, dependent largely upon atmospheric pressure, would not work at such an altitude, but Trevithick's high-pressure engines would. Nine engines and much other mining plant were built by Hazledine and Rastrick and despatched to Peru in 1814, and Trevithick himself followed two years later. However, the war of independence was taking place in Peru, then a Spanish colony, and no sooner had Trevithick, after immense difficulties, put everything in order at the mines then rebels arrived and broke up the machinery, for they saw the mines as a source of supply for the Spanish forces. It was only after innumerable further adventures, during which he encountered and was assisted financially by Robert Stephenson, that Trevithick eventually arrived home in Cornwall in 1827, penniless.He petitioned Parliament for a grant in recognition of his improvements to steam-engines and boilers, without success. He was as inventive as ever though: he proposed a hydraulic power transmission system; he was consulted over steam engines for land drainage in Holland; and he suggested a 1,000 ft (305 m) high tower of gilded cast iron to commemorate the Reform Act of 1832. While working on steam propulsion of ships in 1833, he caught pneumonia, from which he died.[br]BibliographyTrevithick took out fourteen patents, solely or in partnership, of which the most important are: 1802, Construction of Steam Engines, British patent no. 2,599. 1808, Stowing Ships' Cargoes, British patent no. 3,172.Further ReadingH.W.Dickinson and A.Titley, 1934, Richard Trevithick.

34 Momma (Mumma), Jacob
SUBJECT AREA: Metallurgy[br]b. early seventeenth century Germanyd. 1679 England[br]German (naturalized English) immigrant skilled in the manufacture and production of brass, who also mined and smelted copper.[br]The protestant Momma family were well known in Aachen, the seventeenth-century centre of German brass production. Subjected to religious pressures, some members of the family moved to nearby Stolberg, while others migrated to Sweden, starting brass manufacture there. Jacob travelled to England, establishing brassworks with two German partners at Esher in Surrey in 1649; theirs was the only such works in England to survive for more than a few years during the seventeenth century.Jacob, naturalized English by 1660, is often referred to in England as Mummer or another variant of his name. He became respected, serving as a juror, and was appointed a constable in 1661. During the 1660s Momma was engaged in mining copper at Ecton Hill, Staffordshire, where he was credited with introducing gunpowder to English mining technology. He smelted his ore at works nearby in an effort to secure copper supplies, but the whole project was brief and unprofitable.The alternative imported copper required for his brass came mainly from Sweden, its high cost proving a barrier to viable English brass production. In 1662 Momma petitioned Parliament for some form of assistance. A year later he pleaded further for higher tariffs against brass-wire imports as protection from the price manipulation of Swedish exporters. He sought support from the Society of Mineral and Battery Works, the Elizabethan monopoly (see Dockwra, William) claiming jurisdiction over the country's working of brass, but neither petition succeeded. Despite these problems with the high cost of copper supplies in England, Momma continued his business and is recorded as still paying hearth tax on his twenty brass furnaces up to 1664. Although these were abandoned before his death and he claimed to have lost £6,000 on his brassworks, his wire mills survived him for a few years under the management of his son.[br]Further ReadingJ.Morton, 1985, The rise of the modern copper and brass industry: 1690 to 1750, unpublished thesis: University of Birmingham, 16–25.J.Day, 1984, "The continental origins of Bristol Brass", Industrial Archaeology Review 8/1: 32–56.John Robey, 1969, "Ecton copper mines in the seventeenth century", Bulletin of the Peak District Mines Historic Society 4(2):145–55 (the most comprehensive published account).JD -
35 Symington, William
SUBJECT AREA: Ports and shipping[br]b. 1764 Leadhills, Lanarkshire, Scotlandd. 22 March 1831 Wapping, London, England[br]Scottish pioneer of steam navigation.[br]Symington was the son of the Superintendent of the Mines Company in Lanarkshire, and attended the local school. When he was 22 years old he was sent by Gilbert Meason, Manager of the Wanlockhead mines, to Edinburgh University. In 1779 he was working on the assembly of a Watt engine as an apprentice to his brother, George, and in 1786 he started experiments to modify a Watt engine in order to avoid infringing the separate condenser patent. He sought a patent for his alternative, which was paid for by Meason. He constructed a model steam road carriage which was completed in 1786; it was shown in Edinburgh by Meason, attracting interest but inadequate financial support. It had a horizontal cylinder and was non-condensing. No full-sized engine was ever built but the model secured the interest of Patrick Miller, an Edinburgh banker, who ordered an engine from Symington to drive an experimental boat, 25 ft (7.6 m) long with a dual hull, which performed satisfactorily on Dalswinton Loch in 1788. In the following year Miller ordered a larger engine for a bigger boat which was tried on the Forth \& Clyde Canal in December 1789, the component parts having been made by the Carron Company. The engine worked perfectly but had the effect of breaking the paddle wheels. These were repaired and further trials were successful but Miller lost interest and his experiments lapsed. Symington devoted himself thereafter to building stationary engines. He built other engines for mine pumping at Sanquhar and Leadhills before going further afield. In all, he built over thirty engines, about half of them being rotary. In 1800–1 he designed the engine for a boat for Lord Dundas, the Charlotte Dundas; this was apparently the first boat of that name and sailed on both the Forth and Clyde rivers. A second Charlotte Dundas with a horizontal cylinder was to follow and first sailed in January 1803 for the Forth \& Clyde Canal Company. The speed of the boat was only 2 mph (3 km/h) and much was made by its detractors of the damage said to be caused to the canal banks by its wash. Lord Dundas declined to authorize payment of outstanding accounts; Symington received little reward for his efforts. He died in the house of his son-in-law, Dr Robert Bowie, in Wapping, amidst heated controversy about the true inventor of steam navigation.[br]Further ReadingW.S.Harvey and G.Downs-Rose, 1980, William Symington, Inventor and Engine- Builder, London: Mechanical Engineering Publications.IMcN -
36 Wolf, Carl
SUBJECT AREA: Mining and extraction technology[br]b. 23 December 1838 Zwickau, Saxony, Germanyd. 30 January 1915 Zwickau, Saxony, Germany[br]German inventor of the most popular petroleum spirit safety lamp for use in mines.[br]From an old mining family in the Saxon coalfields, Wolf was aware from his youth of the urgent demand for a miner's lamp which would provide adequate light but not provoke firedamp explosions. While working as an engineer in Zwickau, Wolf spent his spare time conducting experiments for such a lamp. The basic concept of his invention was the principle that dangerous concentrations of methane and air would not explode within a small pipe; this had been established almost seventy years earlier by the English chemist Humphrey Davy. By combining and developing certain devices designed by earlier inventors, in 1883 Wolf produced a prototype with a glass cylinder, a primer fixed inside the lamp and a magnetic lock. Until the successful application of electric light, Wolfs invention was the safest and most popular mining safety lamp. Many earlier inventions had failed to address all the problems of lighting for mines; Davy's lamp, for example, would too quickly become sooty and hot. As Wolfs lamp burned petroleum spirit, at first it was mistrusted outside Saxony, but it successfully passed the safety tests in all the leading coal-producing countries at that time. As well as casting a safe, constant light, the appearance of the cap flame could indicate the concentration of fire-damp in the air, thus providing an additional safety measure. Wolfs first patent was soon followed by many others in several countries, and underwent many developments. In 1884 Heinrich Friemann, a merchant from Eisleben, invested capital in the new company of Friemann and Wolf, which became the leading producer of miners' safety lamps. By 1914 they had manufactured over one million lamps, and the company had branches in major mining districts worldwide.[br]Further ReadingF.Schwarz, 1914, Entwickelung und gegenwär-tiger Stand der Grubenbeleuchtung beim Steinkohlen-Bergbau, Gelsenkirchen (a systematic historical outline of safety lamp designs).WK -
