  • 3 Treadgold, Arthur Newton Christian

    [br]
    b. August 1863 Woolsthorpe, Grantham, Lincolnshire, England
    d. 23 March 1951 London, England
    [br]
    English organizer of the Yukon gold fields in Canada, who introduced hydraulic mining.
    [br]
    A direct descendant of Sir Isaac Newton, Treadgold worked as a schoolmaster, mostly at Bath College, for eleven years after completing his studies at Oxford University. He gained a reputation as an energetic teacher who devoted much of his work to sport, but he resigned his post and returned to Oxford; here, in 1897, he learned of the gold rush in the Klondike in the Canadian northwest. With a view to making his own fortune, he took a course in geology at the London Geological College and in 1898 set off for Dawson City, in the Yukon Territory. Working as a correspondent for two English newspapers, he studied thoroughly the situation there; he decided to join the stampede, but as a rather sophisticated gold hustler.
    As there were limited water resources for sluicing or dredging, and underground mining methods were too expensive, Treadgold conceived the idea of hydraulic mining. He designed a ditch-and-siphon system for bringing large amounts of water down from the mountains; in 1901, after three years of negotiation with the Canadian government in Ottawa, he obtained permission to set up the Treadgold Concession to cover the water supply to the Klondike mining claims. This enabled him to supply giant water cannons which battered the hillsides, breaking up the gravel which was then sluiced. Massive protests by the individual miners in the Dawson City region, which he had overrun with his system, led to the concession being rescinded in 1904. Two years later, however, Treadgold began again, forming the Yukon Gold Company, initially in partnership with Solomon Guggenheim; he started work on a channel, completed in 1910, to carry water over a distance of 115 km (70 miles) down to Bonanza Creek. In 1919 he founded the Granville Mining Company, which was to give him control of all the gold-mining operations in the southern Klondike region. When he returned to London in the following year, the company began to fail, and in 1920 he went bankrupt with liabilities totalling more than $2 million. After the Yukon Consolidated Gold Corporation had been formed in 1923, Treadgold returned to the Klondike in 1925 in order to acquire the assets of the operating companies; he gained control and personally supervised the operations. But the company drifted towards disaster, and in 1930 he was dismissed from active management and his shares were cancelled by the courts; he fought for their reinstatement right up until his death.

  • 4 Lucas, Anthony Francis

    [br]
    b. 9 September 1855 Spalato, Dalmatia, Austria-Hungary (now Split, Croatia)
    d. 2 September 1921 Washington, DC, USA
    [br]
    Austrian (naturalized American) mining engineer who successfully applied rotary drilling to oil extraction.
    [br]
    A former Second Lieutenant of the Austrian navy (hence his later nickname "Captain") and graduate of the Polytechnic Institute of Graz, Lucas decided to stay in Michigan when he visited his relatives in 1879. He changed his original name, Lucie, into the form his uncle had adopted and became a naturalized American citizen at the age of 30. He worked in the lumber industry for some years and then became a consulting mechanical and mining engineer in Washington, DC. He began working for a salt-mining company in Louisiana in 1893 and became interested in the geology of the Mexican Gulf region, with a view to prospecting for petroleum. In the course of this work he came to the conclusion that the hills in this elevated area, being geological structures distinct from the surrounding deposits, were natural reservoirs of petroleum. To prove his unusual theory he subsequently chose Spindle Top, near Beaumont, Texas, where in 1899 he began to bore a first oil-well. A second drill-hole, started in October 1900, was put through clay and quicksand. After many difficulties, a layer of rock containing marine shells was reached. When the "gusher" came out on 10 January 1901, it not only opened up a new era in the oil and gas business, but it also led to the future exploration of the terrestrial crust.
    Lucas's boring was a breakthrough for the rotary drilling system, which was still in its early days although its principles had been established by the English engineer Robert Beart in his patent of 1884. It proved to have advantages over the pile-driving of pipes. A pipe with a simple cutter at the lower end was driven with a constantly revolving motion, grinding down on the bottom of the well, thus gouging and chipping its way downward. To deal with the quicksand he adopted the use of large and heavy casings successively telescoped one into the other. According to Fauvelle's method, water was forced through the pipe by means of a pump, so the well was kept full of circulating liquid during drilling, flushing up the mud. When the salt-rock was reached, a diamond drill was used to test the depth and the character of the deposit.
    When the well blew out and flowed freely he developed a preventer in order to save the oil and, even more importantly at the time, to shut the well and to control the oil flow. This assembly, patented in 1903, consisted of a combined system of pipes, valves and casings diverting the stream into a horizontal direction.
    Lucas's fame spread around the world, but as he had to relinquish the larger part of his interest to the oil company supporting the exploration, his financial reward was poor. One year after his success at Spindle Top he started oil exploration in Mexico, where he stayed until 1905, when he resumed his consulting practice in Washington, DC.

  • 7 Edwards, Humphrey

    [br]
    fl. c.1808–25 London (?), England
    d. after 1825 France (?)
    [br]
    English co-developer of Woolf s compound steam engine.
    [br]
    When Arthur Woolf left the Griffin Brewery, London, in October 1808, he formed a partnership with Humphrey Edwards, described as a millwright at Mill Street, Lambeth, where they started an engine works to build Woolf's type of compound engine. A number of small engines were constructed and other ordinary engines modified with the addition of a high-pressure cylinder. Improvements were made in each succeeding engine, and by 1811 a standard form had been evolved. During this experimental period, engines were made with cylinders side by side as well as the more usual layout with one behind the other. The valve gear and other details were also improved. Steam pressure may have been around 40 psi (2.8 kg/cm2). In an advertisement of February 1811, the partners claimed that their engines had been brought to such a state of perfection that they consumed only half the quantity of coal required for engines on the plan of Messrs Boulton \& Watt. Woolf visited Cornwall, where he realized that more potential for his engines lay there than in London; in May 1811 the partnership was dissolved, with Woolf returning to his home county. Edwards struggled on alone in London for a while, but when he saw a more promising future for the engine in France he moved to Paris. On 25 May 1815 he obtained a French patent, a Brevet d'importation, for ten years. A report in 1817 shows that during the previous two years he had imported into France fifteen engines of different sizes which were at work in eight places in various parts of the country. He licensed a mining company in the north of France to make twenty-five engines for winding coal. In France there was always much more interest in rotative engines than pumping ones. Edwards may have formed a partnership with Goupil \& Cie, Dampierre, to build engines, but this is uncertain. He became a member of the firm Scipion, Perrier, Edwards \& Chappert, which took over the Chaillot Foundry of the Perrier Frères in Paris, and it seems that Edwards continued to build steam engines there for the rest of his life. In 1824 it was claimed that he had made about 100 engines in England and another 200 in France, but this is probably an exaggeration.
    The Woolf engine acquired its popularity in France because its compound design was more economical than the single-cylinder type. To enable it to be operated safely, Edwards first modified Woolf s cast-iron boiler in 1815 by placing two small drums over the fire, and then in 1825 replaced the cast iron with wrought iron. The modified boiler was eventually brought back to England in the 1850s as the "French" or "elephant" boiler.

    Most details about Edwards are to be found in the biographies of his partner, Arthur Woolf. For example, see T.R.Harris, 1966, Arthur Woolf, 1766–1837, The Cornish Engineer, Truro: D.Bradford Barton; Rhys Jenkins, 1932–3, "A Cornish Engineer, Arthur Woolf, 1766–1837", Transactions of the Newcomen Society 13. These use information from the originally unpublished part of J.Farey, 1971, A Treatise on the Steam Engine, Vol. II, Newton Abbot: David \& Charles.

    SUBJECT AREA: Civil engineering

    b. 8 September 1780 Eskdalemuir, Dumfriesshire, Scotland
    d. 19 April 1861 London, England
    [br]
    Scottish Colonel-Commandant, Royal Engineers.
    [br]
    At first he was educated by Andrew Little of Lan-gholm. At the age of 14 he was sent to school at Selkirk, where he stayed for two years until joining the Royal Military Academy at Woolwich in August 1796. He was commissioned as Second Lieutenant in the Royal Artillery and transferred to the Royal Engineers on 1 April 1798. He served at Minorca, Malta, Naples, Sicily, Calabria and in the siege of Copenhagen and in other campaigns. He was promoted First Captain in 1807, and was on the staff of Sir John Moore at the battle of Coruna. He was wounded at the siege of Flushing in 1809 and was invalided for a year, employing his time in learning German.
    In November 1810 he published his Essay on Military Policy and Institutions of the British Empire, which ran through four editions. In 1811 he was in command of a company of Royal Military Artificers at Plymouth and there he devised a method of education by which the NCOs and troops could teach themselves without "mathematical masters". His system was a great success and was adopted at Chatham and throughout the corps. In 1812 he was appointed Director of the School of Military Engineering at Chatham. He remained at Chatham until 1841, when he was appointed Inspector-General of Railways. During this period he organized improved systems of sapping, mining, telegraphing, pontooning and exploding gunpowder on land or under water, and prepared pamphlets and courses of instruction in these and other subjects. In May 1836 he started what is probably the most important work for which he is remembered. This, was a book on Limes, Calcareous Cements, Mortar, Stuccos and Concretes. The general adoption of Joseph Aspdin's Portland Cement was largely due to Pasley's recommendation of the material.
    He was married twice: first in 1814 at Chatham to Harriet Cooper; and then on 30 March 1819 at Rochester to Martha Matilda Roberts, with whom he had six children— she died in 1881.

  • 10 Trevithick, Richard

    [br]
    b. 13 April 1771 Illogan, Cornwall, England
    d. 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.

  • 11 Pötsch, Friedrich Hermann

    [br]
    b. 12 December 1842 Biendorf, near Köthen, Germany
    d. 9 June 1902 Dresden, Germany
    [br]
    German mine surveyor, inventor of the freezing process for sinking shafts.
    [br]
    Pötsch was the son of a forest officer and could not easily attend school, with the consequences that it took him a long time to obtain the scholarly education needed to enable him to begin work on a higher level with the mining administration in the duchy of Anhalt in 1868. Seven years later, he was licensed as a Prussian mining surveyor and in this capacity he worked with the mining inspectorate of Aschersleben. During that time he frequently came across shafts for brown-coal mines which had been sunk down to watery strata but then had to be abandoned. His solution to the problem was to freeze the quicksand with a solution of chloride; this was better than the previous attempts in England to instal cooling coils at the bottom of the shaft. Pötsch's conception implied the construction of ice walls with the means of boreholes and refrigerators. By his method a set of boreholes was driven through the watery strata, the smaller pipes contained within the main bore pipes, providing a channel through which calcium chloride was pumped, returning through the longer pipe until the ground was frozen solid. He obtained a patent in 1883 and many leading international journals reported on the method the same year.
    In 1884 he established the Internationale Gesselschaft für Schacht-, Brucken-und Tunnelbau in Magdeburg and he also became Director of the Poetsch-Sooy-Smith Freezing Company in New Jersey, which constructed the first freezing shaft in America in 1888.
    However, Pötsch was successful only for a short period of time and, being a clumsy entrepreneur, he had to dissolve his company in 1894. Unfortunately, his decision to carry out the complete shaft-sinking business did not allow him to concentrate on solving upcoming technical problems of his new process. It was Louis Gebhardt (1861–1924), his former engineer, who took care of development, especially in co-operation with French mining engineers, and thus provided the basis for the freezing process becoming widely used for shaft-sinking in complicated strata ever since.

  • 12 Ingersoll, Simon

    [br]
    b. 3 March 1818 Stamford, Connecticut, USA
    d. 24 July 1894 Stamford, Connecticut, USA
    [br]
    American mechanic, inventor of a rock drill
    [br]
    Ingersoll worked on his father's farm and spent much of his time carrying out all kinds of mechanical experiments until 1839, when he went to Long Island, New York, to work on another farm. Having returned home in 1858, he received several patents for different mechanical devices, but he did not know how to turn his inventive talent into economic profit. His patents were sold to others for money to continue his work and support his family. In 1870, working again on Long Island, he by chance came into contact with New York City's largest contractor, who urged him to design a mechanical rock drill in order to replace hand drills in the rock-excavation business. Within one year Ingersoll built several models and a full-size machine at the machine shop of Henry Clark Sergeant, who contributed several improvements. They secured a joint patent in 1871, which was soon followed by a patent for a rock drill with tappet-valve motion.
    Although the Ingersoll Drill Company was established, he again sold the patent rights and went back to Stamford, where he continued his inventive work and gained several more patents for improving the rock drill. However, he never understood how to make a fortune from his patents, and he died almost penniless. His former partner, Sergeant, who had formed his own drill company on the basis of an entirely novel valve motion which led to compressed air being used as a power source, in 1888 established the Ingersoll- Sergeant Drill Company, which in 1905 merged with Rand Drill Company, which had been a competitor, to form the Ingersoll-Rand Company. This merger led to many achievements in manufacturing rock drills and air compressors at a time when there was growing demand for such machinery.

  • 13 Sperry, Elmer Ambrose

    [br]
    b. 21 October 1860 Cincinnatus, Cortland County, New York, USA
    d. 16 June 1930 Brooklyn, New York, USA
    [br]
    American entrepreneur who invented the gyrocompass.
    [br]
    Sperry was born into a farming community in Cortland County. He received a rudimentary education at the local school, but an interest in mechanical devices was aroused by the agricultural machinery he saw around him. His attendance at the Normal School in Cortland provided a useful theoretical background to his practical knowledge. He emerged in 1880 with an urge to pursue invention in electrical engineering, then a new and growing branch of technology. Within two years he was able to patent and demonstrate his arc lighting system, complete with its own generator, incorporating new methods of regulating its output. The Sperry Electric Light, Motor and Car Brake Company was set up to make and market the system, but it was difficult to keep pace with electric-lighting developments such as the incandescent lamp and alternating current, and the company ceased in 1887 and was replaced by the Sperry Electric Company, which itself was taken over by the General Electric Company.
    In the 1890s Sperry made useful inventions in electric mining machinery and then in electric street-or tramcars, with his patent electric brake and control system. The patents for the brake were important enough to be bought by General Electric. From 1894 to 1900 he was manufacturing electric motor cars of his own design, and in 1900 he set up a laboratory in Washington, where he pursued various electrochemical processes.
    In 1896 he began to work on the practical application of the principle of the gyroscope, where Sperry achieved his most notable inventions, the first of which was the gyrostabilizer for ships. The relatively narrow-hulled steamship rolled badly in heavy seas and in 1904 Ernst Otto Schuck, a German naval engineer, and Louis Brennan in England began experiments to correct this; their work stimulated Sperry to develop his own device. In 1908 he patented the active gyrostabilizer, which acted to correct a ship's roll as soon as it started. Three years later the US Navy agreed to try it on a destroyer, the USS Worden. The successful trials of the following year led to widespread adoption. Meanwhile, in 1910, Sperry set up the Sperry Gyroscope Company to extend the application to commercial shipping.
    At the same time, Sperry was working to apply the gyroscope principle to the ship's compass. The magnetic compass had worked well in wooden ships, but iron hulls and electrical machinery confused it. The great powers' race to build up their navies instigated an urgent search for a solution. In Germany, Anschütz-Kämpfe (1872–1931) in 1903 tested a form of gyrocompass and was encouraged by the authorities to demonstrate the device on the German flagship, the Deutschland. Its success led Sperry to develop his own version: fortunately for him, the US Navy preferred a home-grown product to a German one and gave Sperry all the backing he needed. A successful trial on a destroyer led to widespread acceptance in the US Navy, and Sperry was soon receiving orders from the British Admiralty and the Russian Navy.
    In the rapidly developing field of aeronautics, automatic stabilization was becoming an urgent need. In 1912 Sperry began work on a gyrostabilizer for aircraft. Two years later he was able to stage a spectacular demonstration of such a device at an air show near Paris.
    Sperry continued research, development and promotion in military and aviation technology almost to the last. In 1926 he sold the Sperry Gyroscope Company to enable him to devote more time to invention.

    [br]
    b. 1845 Dukinfield, Cheshire, England
    d. 1 October 1921 Pontefract, Yorkshire, England
    [br]
    English colliery manager, pioneer in machine-holing and the safety of mines.
    [br]
    After Menzies conceived his idea of breaking off coal with machines in 1761, many inventors subsequently followed his proposals through into the practice of underground working. More than one century later, Garforth became one of the principal pioneers of machine-holing combined with the longwall method of working in order to reduce production costs and increase the yield of coal. Having been appointed agent to Pope \& Pearson's Collieries, West Yorkshire, in 1879, of which company he later became Managing Director and Chairman, he gathered a great deal of experience with different methods of cutting coal. The first disc machine was exhibited in London as early as 1851, and ten years later a pick machine was invented. In 1893 he introduced an improved type of deep undercutting machine, his "diamond" disc coal-cutter, driven by compressed air, which also became popular on the European continent.
    Besides the considerable economic advantages it created, the use of machinery for mining coal increased the safety of working in hard and thin seams. The improvement of safety in mining technology was always his primary concern, and as a result of his inventions and his many publications he became the leading figure in the British coal mining industry at the beginning of the twentieth century; safety lamps still carry his name. In 1885 he invented a firedamp detector, and following a severe explosion in 1886 he concentrated on coal-dust experiments. From the information he obtained of the effect of stone-dust on a coal-dust explosion he proposed the stone-dust remedy to prevent explosions of coal-dust. As a result of discussions which lasted for decades and after he had been entrusted with the job of conducting the British coal-dust experiments, in 1921 an Act made it compulsory in all mines which were not naturally wet throughout to treat all roads with incombustible dust so as to ensure that the dust always consisted of a mixture containing not more than 50 per cent combustible matter. In 1901 Garforth erected a surface gallery which represented the damaged roadways of a mine and could be filled with noxious fumes to test self-contained breathing apparata. This gallery formed the model from which all the rescue-stations existing nowadays have been developed.

    b. 1 August 1876 Little Falls, New Jersey, USA
    d. 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.

    b. c.1515
    d. 14 July 1579
    [br]
    English goldsmith and Assay Master of the Royal Mint who attempted to introduce brass production to England.
    [br]
    William Humfrey, goldsmith of the parish of St Vedast, was appointed Assay Master of the Royal Mint in 1561. At the Tower of London he assumed responsibility for the weight of silver and for production standards at a time of intense activity in recoining the debased coinage of the realm. Separation of copper from the debased silver involved liquation techniques which enabled purification of the recovered silver and copper. German co-operation in introducing these methods to England developed their interest in English copper mining, resulting in the formation of the Mines Royal Company. Shareholders in this government-led monopoly included Humfrey, whose assay of Keswick copper ore, mined with German expertise, was bitterly disputed. As a result of this dispute, Humfrey promoted the formation of a smaller monopoly, the Company of Mineral Battery Works, with plans to mine lead and especially the zinc carbonate ore, calamine, using it to introduce brassmaking and wire manufacture into England. Humfrey acquired technical assistance from further skilled German immigrants, relying particularly on Christopher Schutz of Annaberg in Saxony, who claimed experience in such matters. However, the brassmaking project set up at Tintern was abandoned by 1569 after failure to make a brass suitable for manufacturing purposes. The works changed its production to iron wire. Humfrey had meanwhile been under suspicion of embezzlement at the Tower in connection with his work there. He died intestate while involved in litigation regarding infringement of rights and privileges claimed from his introduction of new techniques in later lead-mining activities under the auspices of the Company of Mineral and Battery Works.

    d. 29 June 1883 Fulham, London, England
    [br]
    English architect and inventor, originator of the Hansom cab.
    [br]
    In 1816 he was apprenticed to his father, who was a joiner. After a year his abilities in design and construction were so marked that it was decided that he would have more scope as an architect. He was accordingly apprenticed to a Mr Phillips in York, becoming a clerk to Phillips in 1820. While he served his time he also worked on his own account and taught at a night school. In 1825 he married Hannah Glover and settled in Halifax, where he became Assistant to another architect. In 1828 he became a partner of Edward Welch, with whom he built a number of churches in the north of England. He designed the Town Hall for Birmingham and was responsible for the constructional work until 1833, but he had to become bond because the builders caused him to become bankrupt. He was appointed Manager of the business affairs of Dempster Hemming of Caldicote Hall, which included the landed estates, banking and coal-mining. It was during this period that he designed the "Patent Safety Cab" named after him and popular in Victorian days. The safety element consisted in lowering the centre of gravity by the use of the cranked axle. Hansom sold his rights for £10,000 to a company proposing to exploit the patent, but he was never paid, for the company got into difficulties; Hansom became its temporary Manager in 1839 and put matters right, for which he was paid £300, all he ever made out of the Hansom Cab. In 1842 he brought out the first issue of The Builder, but lack of capital caused him to retire from the journal. He devoted himself from then on to domestic and ecclesiastical architecture, designing many churches, colleges, convents and schools all over Britain and even in Australia and South America. Of note is St Walburga's church, Preston, Lancashire, whose spire is 306 ft (93 m) high. At various times he was in partnership with his younger brother, his eldest son, and with E.W.Pugin with whom he had a disagreement. He was a Catholic and much of his work was for the Catholic Church.

    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.

    b. c. 1647 Gloucestershire, England
    d. 13 October 1718 Bristol, England
    [br]
    English innovator in the mining, smelting and working of copper.
    [br]
    John Coster, son of an iron-forge manager in the Forest of Dean, by the age of 38 was at Bristol, where he was "chief agent and sharer therein" in the new lead-smelting methods using coal fuel. In 1685 the work, under Sir Clement Clerke, was abandoned because of patent rights claimed by Lord Grandison, who financed of earlier attempts. Clerke's business turned to the coal-fired smelting of copper under Coster, later acknowledged as responsible for the subsequent success through using an improved reverberatory furnace which separated coal fume from the ores being smelted. The new technique, applicable also to lead and tin smelting, revitalized copper production and provided a basis for new British industry in both copper and brass manufacture during the following century. Coster went on to manage a copper-smelting works, and by the 1690s was supplying Esher copper-and brass-works in Surrey from his Redbrook, Gloucestershire, works on the River Wye. In the next decade he extended his activities to Cornish copper mining, buying ore and organizing ore sales, and supplying the four major copper and brass companies which by then had become established. He also made copper goods in additional water-powered rolling and hammer mills acquired in the Bristol area. Coster was ably assisted by three sons; of these, John and Robert were mainly active in Cornwall. In 1714 the younger John, with his father, patented an "engine for drawing water out of deep mines". The eldest son, Thomas, was more involved at Redbrook, in South Wales and the Bristol area. A few years after the death of his father, Thomas became partner in the brass company of Bristol and sold them the Redbrook site. He became Member of Parliament for Bristol and, by then the only surviving son, planned a large new smelting works at White Rock, Swansea, South Wales, before his death in 1734. Partners outside the family continued the business under a new name.

  • 20 Williams, Thomas

    [br]
    b. 13 May 1737 Cefn Coch, Anglesey, Wales
    d. 29 November 1802 Bath, England
    [br]
    Welsh lawyer, mine-owner and industrialist.
    [br]
    Williams was articled by his father, Owen Williams of Treffos in Anglesey, to the prominent Flintshire lawyer John Lloyd, whose daughter Catherine he is believed to have married. By 1769 Williams, lessee of the mansion and estate of Llanidan, was an able lawyer with excellent connections in Anglesey. His life changed dramatically when he agreed to act on behalf of the Lewis and Hughes families of Llysdulas, who had begun a lawsuit against Sir Nicholas Bayly of Plas Newydd concerning the ownership and mineral rights of copper mines on the western side of Parys mountain. During a prolonged period of litigation, Williams managed these mines for Margaret Lewis on behalf of Edward Hughes, who was established after a judgement in Chancery in 1776 as one of two legal proprietors, the other being Nicholas Bayly. The latter then decided to lease his portion to the London banker John Dawes, who in 1778 joined Hughes and Thomas Williams when they founded the Parys Mine Company.
    As the active partner in this enterprise, Williams began to establish his own smelting and fabricating works in South Wales, Lancashire and Flintshire, where coal was cheap. He soon broke the power of Associated Smelters, a combine holding the Anglesey mine owners to ransom. The low production cost of Anglesey ore gave him a great advantage over the Cornish mines and he secured very profitable contracts for the copper sheathing of naval and other vessels. After several British and French copper-bottomed ships were lost because of corrosion failure of the iron nails and bolts used to secure the sheathing, Williams introduced a process for manufacturing heavily work-hardened copper bolts and spikes which could be substituted directly for iron fixings, avoiding the corrosion difficulty. His new product was adopted by the Admiralty in 1784 and was soon used extensively in British and European dockyards.
    In 1785 Williams entered into partnership with Lord Uxbridge, son and heir of Nicholas Bayly, to run the Mona Mine Company at the Eastern end of Parys Mountain. This move ended much enmity and litigation and put Williams in effective control of all Anglesey copper. In the same year, Williams, with Matthew Boulton and John Wilkinson, persuaded the Cornish miners to establish a trade cooperative, the Cornish Metal Company, to market their ores. When this began to fall in 1787, Williams took over its administration, assets and stocks and until 1792 controlled the output and sale of all British copper. He became known as the "Copper King" and the output of his many producers was sold by the Copper Offices he established in London, Liverpool and Birmingham. In 1790 he became Member of Parliament for the borough of Great Marlow, and in 1792 he and Edward Hughes established the Chester and North Wales Bank, which in 1900 was absorbed by the Lloyds group.
    After 1792 the output of the Anglesey mines started to decline and Williams began to buy copper from all available sources. The price of copper rose and he was accused of abusing his monopoly. By this time, however, his health had begun to deteriorate and he retreated to Bath.
