    b. 23 August 1847 Sutton, Hull, England

    [br]
    English oil engine pioneer.
    [br]
    William was the second son and one of eleven children of Samuel Priestman, who had moved to Hull after retiring as a corn miller in Kirkstall, Leeds, and who in retirement had become a director of the North Eastern Railway Company. The family were strict Quakers, so William was sent to the Quaker School in Bootham, York. He left school at the age of 17 to start an engineering apprenticeship at the Humber Iron Works, but this company failed so the apprenticeship was continued with the North Eastern Railway, Gateshead. In 1869 he joined the hydraulics department of Sir William Armstrong \& Company, Newcastle upon Tyne, but after a year there his father financed him in business at a small, run down works, the Holderness Foundry, Hull. He was soon joined by his brother, Samuel, their main business being the manufacture of dredging equipment (grabs), cranes and winches. In the late 1870s William became interested in internal combustion engines. He took a sublicence to manufacture petrol engines to the patents of Eugène Etève of Paris from the British licensees, Moll and Dando. These engines operated in a similar manner to the non-compression gas engines of Lenoir. Failure to make the two-stroke version of this engine work satisfactorily forced him to pay royalties to Crossley Bros, the British licensees of the Otto four-stroke patents.
    Fear of the dangers of petrol as a fuel, reflected by the associated very high insurance premiums, led William to experiment with the use of lamp oil as an engine fuel. His first of many patents was for a vaporizer. This was in 1885, well before Ackroyd Stuart. What distinguished the Priestman engine was the provision of an air pump which pressurized the fuel tank, outlets at the top and bottom of which led to a fuel atomizer injecting continuously into a vaporizing chamber heated by the exhaust gases. A spring-loaded inlet valve connected the chamber to the atmosphere, with the inlet valve proper between the chamber and the working cylinder being camoperated. A plug valve in the fuel line and a butterfly valve at the inlet to the chamber were operated, via a linkage, by the speed governor; this is believed to be the first use of this method of control. It was found that vaporization was only partly achieved, the higher fractions of the fuel condensing on the cylinder walls. A virtue was made of this as it provided vital lubrication. A starting system had to be provided, this comprising a lamp for preheating the vaporizing chamber and a hand pump for pressurizing the fuel tank.
    Engines of 2–10 hp (1.5–7.5 kW) were exhibited to the press in 1886; of these, a vertical engine was installed in a tram car and one of the horizontals in a motor dray. In 1888, engines were shown publicly at the Royal Agricultural Show, while in 1890 two-cylinder vertical marine engines were introduced in sizes from 2 to 10 hp (1.5–7.5 kW), and later double-acting ones up to some 60 hp (45 kW). First, clutch and gearbox reversing was used, but reversing propellers were fitted later (Priestman patent of 1892). In the same year a factory was established in Philadelphia, USA, where engines in the range 5–20 hp (3.7–15 kW) were made. Construction was radically different from that of the previous ones, the bosses of the twin flywheels acting as crank discs with the main bearings on the outside.
    On independent test in 1892, a Priestman engine achieved a full-load brake thermal efficiency of some 14 per cent, a very creditable figure for a compression ratio limited to under 3:1 by detonation problems. However, efficiency at low loads fell off seriously owing to the throttle governing, and the engines were heavy, complex and expensive compared with the competition.
    Decline in sales of dredging equipment and bad debts forced the firm into insolvency in 1895 and receivers took over. A new company was formed, the brothers being excluded. However, they were able to attend board meetings, but to exert no influence. Engine activities ceased in about 1904 after over 1,000 engines had been made. It is probable that the Quaker ethics of the brothers were out of place in a business that was becoming increasingly cut-throat. William spent the rest of his long life serving others.

    b. 31 December 1888 Thizy, Rhône, France
    d. 15 August 1960 Fontenoy-aux-Roses, France
    [br]
    French metallurgist, inventor of the alloys Elinvar and Platinite and of the method of strengthening nickel-chromium alloys by a precipitate ofNi3Al which provided the basis of all later super-alloy development.
    [br]
    Soon after graduating from the Ecole des Mines at St-Etienne in 1910, Chevenard joined the Société de Commentry Fourchambault et Decazeville at their steelworks at Imphy, where he remained for the whole of his career. Imphy had for some years specialized in the production of nickel steels. From this venture emerged the first austenitic nickel-chromium steel, containing 6 per cent chromium and 22–4 per cent nickel and produced commercially in 1895. Most of the alloys required by Guillaume in his search for the low-expansion alloy Invar were made at Imphy. At the Imphy Research Laboratory, established in 1911, Chevenard conducted research into the development of specialized nickel-based alloys. His first success followed from an observation that some of the ferro-nickels were free from the low-temperature brittleness exhibited by conventional steels. To satisfy the technical requirements of Georges Claude, the French cryogenic pioneer, Chevenard was then able in 1912 to develop an alloy containing 55–60 per cent nickel, 1–3 per cent manganese and 0.2–0.4 per cent carbon. This was ductile down to −190°C, at which temperature carbon steel was very brittle.
    By 1916 Elinvar, a nickel-iron-chromium alloy with an elastic modulus that did not vary appreciably with changes in ambient temperature, had been identified. This found extensive use in horology and instrument manufacture, and even for the production of high-quality tuning forks. Another very popular alloy was Platinite, which had the same coefficient of thermal expansion as platinum and soda glass. It was used in considerable quantities by incandescent-lamp manufacturers for lead-in wires. Other materials developed by Chevenard at this stage to satisfy the requirements of the electrical industry included resistance alloys, base-metal thermocouple combinations, magnetically soft high-permeability alloys, and nickel-aluminium permanent magnet steels of very high coercivity which greatly improved the power and reliability of car magnetos. Thermostatic bimetals of all varieties soon became an important branch of manufacture at Imphy.
    During the remainder of his career at Imphy, Chevenard brilliantly elaborated the work on nickel-chromium-tungsten alloys to make stronger pressure vessels for the Haber and other chemical processes. Another famous alloy that he developed, ATV, contained 35 per cent nickel and 11 per cent chromium and was free from the problem of stress-induced cracking in steam that had hitherto inhibited the development of high-power steam turbines. Between 1912 and 1917, Chevenard recognized the harmful effects of traces of carbon on this type of alloy, and in the immediate postwar years he found efficient methods of scavenging the residual carbon by controlled additions of reactive metals. This led to the development of a range of stabilized austenitic stainless steels which were free from the problems of intercrystalline corrosion and weld decay that then caused so much difficulty to the manufacturers of chemical plant.
    Chevenard soon concluded that only the nickel-chromium system could provide a satisfactory basis for the subsequent development of high-temperature alloys. The first published reference to the strengthening of such materials by additions of aluminium and/or titanium occurs in his UK patent of 1929. This strengthening approach was adopted in the later wartime development in Britain of the Nimonic series of alloys, all of which depended for their high-temperature strength upon the precipitated compound Ni3Al.
    In 1936 he was studying the effect of what is now known as "thermal fatigue", which contributes to the eventual failure of both gas and steam turbines. He then published details of equipment for assessing the susceptibility of nickel-chromium alloys to this type of breakdown by a process of repeated quenching. Around this time he began to make systematic use of the thermo-gravimetrie balance for high-temperature oxidation studies.

  • 3 Riley, James

    SUBJECT AREA: Metallurgy
    [br]
    b. 1840 Halifax, England
    d. 15 July 1910 Harrogate, England
    [br]
    English steelmaker who promoted the manufacture of low-carbon bulk steel by the open-hearth process for tin plate and shipbuilding; pioneer of nickel steels.
    [br]
    After working as a millwright in Halifax, Riley found employment at the Ormesby Ironworks in Middlesbrough until, in 1869, he became manager of the Askam Ironworks in Cumberland. Three years later, in 1872, he was appointed Blast-furnace Manager at the pioneering Siemens Steel Company's works at Landore, near Swansea in South Wales. Using Spanish ore, he produced the manganese-rich iron (spiegeleisen) required as an additive to make satisfactory steel. Riley was promoted in 1874 to be General Manager at Landore, and he worked with William Siemens to develop the use of the latter's regenerative furnace for the production of open-hearth steel. He persuaded Welsh makers of tin plate to use sheets rolled from lowcarbon (mild) steel instead of from charcoal iron and, partly by publishing some test results, he was instrumental in influencing the Admiralty to build two naval vessels of mild steel, the Mercury and the Iris.
    In 1878 Riley moved north on his appointment as General Manager of the Steel Company of Scotland, a firm closely associated with Charles Tennant that was formed in 1872 to make steel by the Siemens process. Already by 1878, fourteen Siemens melting furnaces had been erected, and in that year 42,000 long tons of ingots were produced at the company's Hallside (Newton) Works, situated 8 km (5 miles) south-east of Glasgow. Under Riley's leadership, steelmaking in open-hearth furnaces was initiated at a second plant situated at Blochairn. Plates and sections for all aspects of shipbuilding, including boilers, formed the main products; the company also supplied the greater part of the steel for the Forth (Railway) Bridge. Riley was associated with technical modifications which improved the performance of steelmaking furnaces using Siemens's principles. He built a gasfired cupola for melting pig-iron, and constructed the first British "universal" plate mill using three-high rolls (Lauth mill).
    At the request of French interests, Riley investigated the properties of steels containing various proportions of nickel; the report that he read before the Iron and Steel Institute in 1889 successfully brought to the notice of potential users the greatly enhanced strength that nickel could impart and its ability to yield alloys possessing substantially lower corrodibility.
    The Steel Company of Scotland paid dividends in the years to 1890, but then came a lean period. In 1895, at the age of 54, Riley moved once more to another employer, becoming General Manager of the Glasgow Iron and Steel Company, which had just laid out a new steelmaking plant at Wishaw, 25 km (15 miles) south-east of Glasgow, where it already had blast furnaces. Still the technical innovator, in 1900 Riley presented an account of his experiences in introducing molten blast-furnace metal as feed for the open-hearth steel furnaces. In the early 1890s it was largely through Riley's efforts that a West of Scotland Board of Conciliation and Arbitration for the Manufactured Steel Trade came into being; he was its first Chairman and then its President.
    In 1899 James Riley resigned from his Scottish employment to move back to his native Yorkshire, where he became his own master by acquiring the small Richmond Ironworks situated at Stockton-on-Tees. Although Riley's 1900 account to the Iron and Steel Institute was the last of the many of which he was author, he continued to contribute to the discussion of papers written by others.

    b. 17 October 1801 Birmingham England
    d. 22 September 1865 Pool Park, Denbighshire, England
    [br]
    English pioneer in electroplating.
    [br]
    He was apprenticed to his uncles, makers of metalware, in 1815 and showed such aptitude for business that he was taken into partnership. On their deaths, Elkington assumed sole ownership of the business. In conjunction with his cousin Henry (1810–52), by unrelenting enterprise, he established an industry for electroplating and electrogilding. Up until c.1840, silver-plated goods were produced by rolling or soldering thin sheets of silver to a base metal, such as copper. Back in 1801, the English chemist William Wollaston had deposited one metal upon another by means of an electric current generated from a voltaic pile or battery. In the 1830s, certain inventors, such as Bessemer used this result to produce plated articles and these efforts in turn induced the Elkingtons to apply the method in their trade. In 1836 and 1837 they took out patents for "mercurial gilding", and one patent of 1838 refers to a separate electric current. In 1840 they bought from John Wright, a Birmingham surgeon, his discovery of what proved to be the best electroplating solution: namely, solutions of cyanides of gold and silver in potassium cyanide. They also purchased rights to use the electric machine invented by J.S. Woolrich. Armed with these techniques, the Elkingtons produced in their large new works in Newhall Street a wide range of gold-and silver-plated decorative and artistic ware. Henry was particularly active on the artistic side of the business, as was their employee Alexander Parkes. For some twenty-five years, Britain enjoyed a virtual monopoly of this kind of ware, due largely to the enterprise of the Elkingtons, although by the end of the century rising tariffs had closed many foreign markets and the lead had passed to Germany. George spent all his working life in Birmingham, taking some part in the public life of the city. He was a governor of King Edward's Grammar School and a borough magistrate. He was also a caring employer, setting up houses and schools for his workers.

  • 6 Stephenson, Robert

    [br]
    b. 16 October 1803 Willington Quay, Northumberland, England
    d. 12 October 1859 London, England
    [br]
    English engineer who built the locomotive Rocket and constructed many important early trunk railways.
    [br]
    Robert Stephenson's father was George Stephenson, who ensured that his son was educated to obtain the theoretical knowledge he lacked himself. In 1821 Robert Stephenson assisted his father in his survey of the Stockton \& Darlington Railway and in 1822 he assisted William James in the first survey of the Liverpool \& Manchester Railway. He then went to Edinburgh University for six months, and the following year Robert Stephenson \& Co. was named after him as Managing Partner when it was formed by himself, his father and others. The firm was to build stationary engines, locomotives and railway rolling stock; in its early years it also built paper-making machinery and did general engineering.
    In 1824, however, Robert Stephenson accepted, perhaps in reaction to an excess of parental control, an invitation by a group of London speculators called the Colombian Mining Association to lead an expedition to South America to use steam power to reopen gold and silver mines. He subsequently visited North America before returning to England in 1827 to rejoin his father as an equal and again take charge of Robert Stephenson \& Co. There he set about altering the design of steam locomotives to improve both their riding and their steam-generating capacity. Lancashire Witch, completed in July 1828, was the first locomotive mounted on steel springs and had twin furnace tubes through the boiler to produce a large heating surface. Later that year Robert Stephenson \& Co. supplied the Stockton \& Darlington Railway with a wagon, mounted for the first time on springs and with outside bearings. It was to be the prototype of the standard British railway wagon. Between April and September 1829 Robert Stephenson built, not without difficulty, a multi-tubular boiler, as suggested by Henry Booth to George Stephenson, and incorporated it into the locomotive Rocket which the three men entered in the Liverpool \& Manchester Railway's Rainhill Trials in October. Rocket, was outstandingly successful and demonstrated that the long-distance steam railway was practicable.
    Robert Stephenson continued to develop the locomotive. Northumbrian, built in 1830, had for the first time, a smokebox at the front of the boiler and also the firebox built integrally with the rear of the boiler. Then in Planet, built later the same year, he adopted a layout for the working parts used earlier by steam road-coach pioneer Goldsworthy Gurney, placing the cylinders, for the first time, in a nearly horizontal position beneath the smokebox, with the connecting rods driving a cranked axle. He had evolved the definitive form for the steam locomotive.
    Also in 1830, Robert Stephenson surveyed the London \& Birmingham Railway, which was authorized by Act of Parliament in 1833. Stephenson became Engineer for construction of the 112-mile (180 km) railway, probably at that date the greatest task ever undertaken in of civil engineering. In this he was greatly assisted by G.P.Bidder, who as a child prodigy had been known as "The Calculating Boy", and the two men were to be associated in many subsequent projects. On the London \& Birmingham Railway there were long and deep cuttings to be excavated and difficult tunnels to be bored, notoriously at Kilsby. The line was opened in 1838.
    In 1837 Stephenson provided facilities for W.F. Cooke to make an experimental electrictelegraph installation at London Euston. The directors of the London \& Birmingham Railway company, however, did not accept his recommendation that they should adopt the electric telegraph and it was left to I.K. Brunel to instigate the first permanent installation, alongside the Great Western Railway. After Cooke formed the Electric Telegraph Company, Stephenson became a shareholder and was Chairman during 1857–8.
    Earlier, in the 1830s, Robert Stephenson assisted his father in advising on railways in Belgium and came to be increasingly in demand as a consultant. In 1840, however, he was almost ruined financially as a result of the collapse of the Stanhope \& Tyne Rail Road; in return for acting as Engineer-in-Chief he had unwisely accepted shares, with unlimited liability, instead of a fee.
    During the late 1840s Stephenson's greatest achievements were the design and construction of four great bridges, as part of railways for which he was responsible. The High Level Bridge over the Tyne at Newcastle and the Royal Border Bridge over the Tweed at Berwick were the links needed to complete the East Coast Route from London to Scotland. For the Chester \& Holyhead Railway to cross the Menai Strait, a bridge with spans as long-as 460 ft (140 m) was needed: Stephenson designed them as wrought-iron tubes of rectangular cross-section, through which the trains would pass, and eventually joined the spans together into a tube 1,511 ft (460 m) long from shore to shore. Extensive testing was done beforehand by shipbuilder William Fairbairn to prove the method, and as a preliminary it was first used for a 400 ft (122 m) span bridge at Conway.
    In 1847 Robert Stephenson was elected MP for Whitby, a position he held until his death, and he was one of the exhibition commissioners for the Great Exhibition of 1851. In the early 1850s he was Engineer-in-Chief for the Norwegian Trunk Railway, the first railway in Norway, and he also built the Alexandria \& Cairo Railway, the first railway in Africa. This included two tubular bridges with the railway running on top of the tubes. The railway was extended to Suez in 1858 and for several years provided a link in the route from Britain to India, until superseded by the Suez Canal, which Stephenson had opposed in Parliament. The greatest of all his tubular bridges was the Victoria Bridge across the River St Lawrence at Montreal: after inspecting the site in 1852 he was appointed Engineer-in-Chief for the bridge, which was 1 1/2 miles (2 km) long and was designed in his London offices. Sadly he, like Brunel, died young from self-imposed overwork, before the bridge was completed in 1859.

    [br]
    b. 29 March 1819 Greenville, New York, USA
    d. 8 November 1880 Bethlehem, Pennsylvania, USA
    [br]
    American pioneer oil driller.
    [br]
    He worked on his father's farm, was a clerk in a hotel and a store, and then became an express agent at a railway company in Springfield, Massachusetts, c.1845. After he had been working as a railway conductor in New Haven, Connecticut, for eight years, he resigned because of ill health. Owning some stocks in a Pennsylvania rock-oil company, which gathered oil from ground-level seepages mainly for medicinal use, he was engaged by this company and moved to Titusville, Pennsylvania, at the age of almost 40. After studying salt-well drilling by cable tool, which was still percussive, he became enthusiastic about the idea of using the same method to drill for oil, especially after researches in chemistry had revealed this new sort of fossil energy some years before.
    As a manager of the Seneca Oil Company, which referred to him as "Colonel" in letters of introduction simply to impress people with such titles, Drake began drilling in 1858, almost at the same time as pole-tool drilling for oil was started in Germany. His main contribution to the technology was the use of an iron pipe driven through the quicksand and the bedrock to prevent the bore-hole from filling. After nineteen months he struck oil at a depth of 21 m (69 ft) in August 1859. This was the first time that petroleum was struck at its source and the first proof of the presence of oil reservoirs within the earth's surface. Drake inaugurated the search for and the exploitation of the deep oil resources of the world and he initiated the science of petroleum engineering which became established at the beginning of the twentieth century.
    Drake failed to patent his drilling method; he was content being an oil commission merchant and Justice of the Peace in Titusville, which like other places in Pennsylvania became a boom town. Four years later he went to New York, where he lost all his money in oil speculations. He became very ill again and lived in poverty in Vermont and New Jersey until 1873, when he moved to Bethlehem, Pennsylvania, where he was pensioned by the state of Pennsylvania. The city of Titusville erected a monument to him and founded the Drake Museum.

    b. 1837 Langon, Bordeaux, France
    d. 19 August 1920 Agen, France
    [br]
    French scientist and pioneer of colour photography.
    [br]
    The son of a tax collector, Ducos du Hauron began researches into colour photography soon after the publication of Clerk Maxwell's experiment in 1861. In a communication sent in 1862 for presentation at the Académie des Sciences, but which was never read, he outlined a number of methods for photography of colours. Subsequently, in his book Les Couleurs en photographie, published in 1869, he outlined most of the principles of additive and subtractive colour photography that were later actually used. He covered additive processes, developed from Clerk Maxwell's demonstrations, and subtractive processes which could yield prints. At the time, the photographic materials available prevented the processes from being employed effectively. The design of his Chromoscope, in which transparent reflectors could be used to superimpose three additive images, was sound, however, and formed the basis of a number of later devices. He also proposed an additive system based on the use of a screen of fine red, yellow and blue lines, through which the photograph was taken and viewed. The lines blended additively when seen from a certain distance. Many years later, in 1907, Ducos du Hauron was to use this principle in an early commercial screen-plate process, Omnicolore. With his brother Alcide, he published a further work in 1878, Photographie des Couleurs, which described some more-practical subtractive processes. A few prints made at this time still survive and they are remarkably good for the period. In a French patent of 1895 he described yet another method for colour photography. His "polyfolium chromodialytique" involved a multiple-layer package of separate red-, green-and blue-sensitive materials and filters, which with a single exposure would analyse the scene in terms of the three primary colours. The individual layers would be separated for subsequent processing and printing. In a refined form, this is the principle behind modern colour films. In 1891 he patented and demonstrated the anaglyph method of stereoscopy, using superimposed red and green left and right eye images viewed through green and red filters. Ducos du Hauron's remarkable achievement was to propose theories of virtually all the basic methods of colour photography at a time when photographic materials were not adequate for the purpose of proving them correct. For his work on colour photography he was awarded the Progress Medal of the Royal Photographic Society in 1900, but despite his major contributions to colour photography he remained in poverty for much of his later life.

    [br]
    b. 9 April 1864 Liverpool, England
    d. 13 January 1930 Zurich, Switzerland
    [br]
    English manufacturing engineer and inventor, a pioneer and early advocate of high-voltage alternating-current electric-power systems.
    [br]
    Ferranti, who had taken an interest in electrical and mechanical devices from an early age, was educated at St Augustine's College in Ramsgate and for a short time attended evening classes at University College, London. Rather than pursue an academic career, Ferranti, who had intense practical interests, found employment in 1881 with the Siemens Company (see Werner von Siemens) in their experimental department. There he had the opportunity to superintend the installation of electric-lighting plants in various parts of the country. Becoming acquainted with Alfred Thomson, an engineer, Ferranti entered into a short-lived partnership with him to manufacture the Ferranti alternator. This generator, with a unique zig-zag armature, had an efficiency exceeding that of all its rivals. Finding that Sir William Thomson had invented a similar machine, Ferranti formed a company with him to combine the inventions and produce the Ferranti- Thomson machine. For this the Hammond Electric Light and Power Company obtained the sole selling rights.
    In 1885 the Grosvenor Gallery Electricity Supply Corporation was having serious problems with its Gaulard and Gibbs series distribution system. Ferranti, when consulted, reviewed the design and recommended transformers connected across constant-potential mains. In the following year, at the age of 22, he was appointed Engineer to the company and introduced the pattern of electricity supply that was eventually adopted universally. Ambitious plans by Ferranti for London envisaged the location of a generating station of unprecedented size at Deptford, about eight miles (13 km) from the city, a departure from the previous practice of placing stations within the area to be supplied. For this venture the London Electricity Supply Corporation was formed. Ferranti's bold decision to bring the supply from Deptford at the hitherto unheard-of pressure of 10,000 volts required him to design suitable cables, transformers and generators. Ferranti planned generators with 10,000 hp (7,460 kW)engines, but these were abandoned at an advanced stage of construction. Financial difficulties were caused in part when a Board of Trade enquiry in 1889 reduced the area that the company was able to supply. In spite of this adverse situation the enterprise continued on a reduced scale. Leaving the London Electricity Supply Corporation in 1892, Ferranti again started his own business, manufacturing electrical plant. He conceived the use of wax-impregnated paper-insulated cables for high voltages, which formed a landmark in the history of cable development. This method of flexible-cable manufacture was used almost exclusively until synthetic materials became available. In 1892 Ferranti obtained a patent which set out the advantages to be gained by adopting sector-shaped conductors in multi-core cables. This was to be fundamental to the future design and development of such cables.
    A total of 176 patents were taken out by S.Z. de Ferranti. His varied and numerous inventions included a successful mercury-motor energy meter and improvements to textile-yarn produc-tion. A transmission-line phenomenon where the open-circuit voltage at the receiving end of a long line is greater than the sending voltage was named the Ferranti Effect after him.

    b. 13 July 1811 Glasgow, Scotland
    d. 13 May 1883 Wemyss Bay, Scotland
    [br]
    Scottish chemist and pioneer petroleum technologist.
    [br]
    Young's early education took place in the evenings, after the day's work in his father's joinery. From 1830 he studied chemistry at the evening classes in Glasgow given by the distinguished Scottish chemist Thomas Graham (1805–69) and soon afterwards became Graham's assistant. When Graham moved to University College London in 1837, Young accompanied him.
    From 1839 he was employed in the chemical industry, first with James Muspratt at St Helens, Lancashire, and from 1843 with Tennant \& Company in Manchester. In 1848 his attention was drawn to an oil seepage in a mine at Alfreton, Derbyshire, of some 300 gallons per day; he set up his own works there to extract an oil that could be used for lighting and lubrication. When this source of oil was exhausted, three years later, Young moved to Lothian in Scotland. By distillation, he extracted oil from the oil-shale deposits there and thus founded the Scottish oil-shale industry: he obtained a high yield of paraffin oil for lighting and heating, and was a pioneer in the use of chemical methods in extracting and treating oil. In 1866 he disposed of his company for no less than £400,000. Young's other activities included measuring the speed of light by Fizeau's method and giving financial support to the expeditions of David Livingstone, who had been a fellow student in Glasgow.

    [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.

    [br]
    French pioneer in the development of the structural use of iron reinforcement of concrete.
    [br]
    As early as 1847, Coignet built some houses of poured (unreinforced) concrete, but in 1852, in a house at 72 rue Charles Michel, in St Denis, he first employed his own system of what he called béton armé, meaning reinforced concrete. Coignet exhibited his technique of reinforcement using iron bars at the Paris Exposition of 1855 and was quoted as forecasting that cement, concrete and iron were destined to replace stone. A year later he patented a method of reinforcing concrete with iron tirants, a reference to the metal ropes or bars being under tension, and in 1861 he published a treatise on concrete. Coignet is credited with building several examples of concrete shell casing to iron structures in conjunction with different architects—e.g., the Church of Le Vésinet (1863, Seine et Oise).
