1 Riley, James
SUBJECT AREA: Metallurgy[br]b. 1840 Halifax, Englandd. 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.[br]Principal Honours and DistinctionsPresident, West of Scotland Iron and Steel Institute 1893–5.

2 Talbot, Benjamin
SUBJECT AREA: Metallurgy[br]b. 19 September 1864 Wellington, Shropshire, Englandd. 16 December 1947 Solberge Hall, Northallerton, Yorkshire, England[br]Talbot, William Henry Fox English steelmaker and businessman who introduced a technique for producing steel "continuously" in large tilting basic-lined open-hearth furnaces.[br]After spending some years at his father's Castle Ironworks and at Ebbw Vale Works, Talbot travelled to the USA in 1890 to become Superintendent of the Southern Iron and Steel Company of Chattanooga, Tennessee, where he initiated basic open-hearth steelmaking and a preliminary slag washing to remove silicon. In 1893 he moved to Pennsylvania as Steel Superintendent at the Pencoyd works; there, six years later, he began his "continuous" steelmaking process. Returning to Britain in 1900, Talbot marketed the technique: after ten years it was in successful use in Britain, continental Europe and the USA; it promoted the growth of steel production.Meanwhile its originator had joined the Cargo Fleet Iron Company Limited on Teesside, where he was made Managing Director in 1907. Twelve years later he assumed, in addition, the same position in the allied South Durham Steel and Iron Company Limited. While remaining Managing Director, he was appointed Deputy Chairman of both companies in 1925, and Chairman in 1940. The companies he controlled survived the depressed 1920s and 1930s and were significant contributors to British steel output, with a capacity of more than half a million tonnes per year.[br]Principal Honours and DistinctionsPresident, Iron and Steel Institute 1928, and (British) National Federation of Iron and Steel Manufacturers.

3 Dudley, Dud
SUBJECT AREA: Metallurgy[br]b. 1599d. 25 October 1684 Worcester, England[br]English ironmaster who drew attention to the need to change from charcoal to coal as a fuel for iron smelting.[br]Dudley was the fourth natural son of Edward Sutton, fifth Baron Dudley. In 1619 he was summoned from Balliol College, Oxford, to superintend his father's ironworks at Pensnet in Worcestershire. There had long been concern at the destruction of the forests in order to make charcoal for the smelting of iron ore, and unsuccessful attempts had been made to substitute coal as a fuel. Finding that charcoal was in short supply and coal plentiful near Pensnet, Dudley was stimulated by these attempts to try the process for himself. He claimed to have made good, marketable iron and in 1621 his father obtained a patent from the King to protect his process for thirty-one years. After a serious flood, Dudley moved to Staffordshire and continued his efforts there. In 1639 he was granted a further patent for making iron with coal. Although he probably made some samples of good iron, more by luck than judgement, it is hardly possible that he achieved consistent success. He blamed this on the machinations of other ironmasters. The day that King Charles II landed in England to assume his throne', Dudley petitioned him to renew his patents, but he was refused and he ceased to promote his invention. In 1665, however, he published his celebrated book Metallum Martis, Iron Made with Pit-Coaky Sea-Coale…. In this he described his efforts in general terms, but neither there nor in his patents does he give any technical details of his methods. He implied the use of slack or small coal from the Staffordshire Thick or Ten Yard coal, but this has a sulphur content that would have rendered the iron unusable; in addition, this coal would not have been suitable for converting to coke in order to remove the sulphur. Nevertheless, Dudley recognized the need to change from charcoal to coal as a fuel for iron smelting and drew attention to it, even though he himself achieved little success.[br]Further ReadingH.R.Schubert, 1957, History of the British Iron and Steel Industry AD 430 to AD 1775, London: Routledge \& Kegan Paul.W.K.V.Gale, 1967, The British Iron and Steel Industry: A Technical History, London (provides brief details of Dudley's life in relation to the history of ironmaking).LRD -
4 Darby, Abraham
SUBJECT AREA: Metallurgy[br]b. 1678 near Dudley, Worcestershire, Englandd. 5 May 1717 Madely Court, Coalbrookdale, Shropshire, England[br]English ironmaster, inventor of the coke smelting of iron ore.[br]Darby's father, John, was a farmer who also worked a small forge to produce nails and other ironware needed on the farm. He was brought up in the Society of Friends, or Quakers, and this community remained important throughout his personal and working life. Darby was apprenticed to Jonathan Freeth, a malt-mill maker in Birmingham, and on completion of his apprenticeship in 1699 he took up the trade himself in Bristol. Probably in 1704, he visited Holland to study the casting of brass pots and returned to Bristol with some Dutch workers, setting up a brassworks at Baptist Mills in partnership with others. He tried substituting cast iron for brass in his castings, without success at first, but in 1707 he was granted a patent, "A new way of casting iron pots and other pot-bellied ware in sand without loam or clay". However, his business associates were unwilling to risk further funds in the experiments, so he withdrew his share of the capital and moved to Coalbrookdale in Shropshire. There, iron ore, coal, water-power and transport lay close at hand. He took a lease on an old furnace and began experimenting. The shortage and expense of charcoal, and his knowledge of the use of coke in malting, may well have led him to try using coke to smelt iron ore. The furnace was brought into blast in 1709 and records show that in the same year it was regularly producing iron, using coke instead of charcoal. The process seems to have been operating successfully by 1711 in the production of cast-iron pots and kettles, with some pig-iron destined for Bristol. Darby prospered at Coalbrookdale, employing coke smelting with consistent success, and he sought to extend his activities in the neighbourhood and in other parts of the country. However, ill health prevented him from pursuing these ventures with his previous energy. Coke smelting spread slowly in England and the continent of Europe, but without Darby's technological breakthrough the ever-increasing demand for iron for structures and machines during the Industrial Revolution simply could not have been met; it was thus an essential component of the technological progress that was to come.Darby's eldest son, Abraham II (1711–63), entered the Coalbrookdale Company partnership in 1734 and largely assumed control of the technical side of managing the furnaces and foundry. He made a number of improvements, notably the installation of a steam engine in 1742 to pump water to an upper level in order to achieve a steady source of water-power to operate the bellows supplying the blast furnaces. When he built the Ketley and Horsehay furnaces in 1755 and 1756, these too were provided with steam engines. Abraham II's son, Abraham III (1750–89), in turn, took over the management of the Coalbrookdale works in 1768 and devoted himself to improving and extending the business. His most notable achievement was the design and construction of the famous Iron Bridge over the river Severn, the world's first iron bridge. The bridge members were cast at Coalbrookdale and the structure was erected during 1779, with a span of 100 ft (30 m) and height above the river of 40 ft (12 m). The bridge still stands, and remains a tribute to the skill and judgement of Darby and his workers.[br]Further ReadingA.Raistrick, 1989, Dynasty of Iron Founders, 2nd edn, Ironbridge Gorge Museum Trust (the best source for the lives of the Darbys and the work of the company).H.R.Schubert, 1957, History of the British Iron and Steel Industry AD 430 to AD 1775, London: Routledge \& Kegan Paul.LRD -
5 Hadfield, Sir Robert Abbott
SUBJECT AREA: Metallurgy[br]b. 28 November 1858 Attercliffe, Sheffield, Yorkshire, Englandd. 30 September 1940 Kingston Hill, Surrey, England[br]English metallurgist and pioneer in alloy steels.[br]Hadfield's father, Robert, set up a steelworks in Sheffield in 1872, one of the earliest to specialize in steel castings. After his education in Sheffield, during which he showed an interest in chemistry, Hadfield entered his father's works. His first act was to set up a laboratory, where he began systematically experimenting with alloy steels in order to improve the quality of the products of the family firm. In 1883 Hadfield found that by increasing the manganese content to 12.5 per cent, with a carbon content of 1.4 per cent, the resulting alloy showed extraordinary resistance to abrasive wear even though it was quite soft. It was soon applied in railway points and crossings, crushing and grinding machinery, and wherever great resistance to wear is required. Its lack of brittleness led to its use in steel helmets during the First World War. Hadfield's manganese steel was also non-magnetic, which was later of importance in the electrical industry. Hadfield's other great invention was that of silicon steel. Again after careful and systematic laboratory work, Hadfield found that a steel containing 3–4 per cent silicon and as little as possible of other elements was highly magnetic, which was to prove important in the electrical industry (e.g. reducing the weight and bulk of electrical transformers). Hadfield took over the firm on the death of his father in 1888, but he continued to lay great stress on the need for laboratory research to improve the quality and range of products. The steel-casting side of the business led to a flourishing armaments industry, and this, together with their expertise in alloy steels, made Hadfield's one of the great names in Sheffield and British steel until, sadly, it succumbed along with so many other illustrious names during the British economic recession of 1983. Hadfield had a keen interest in metallurgical history, particularly in his characteristically thorough examination of the alloys of iron prepared by Faraday at the Royal Institution. Hadfield was an enlightened employer and was one of the first to introduce the eight-hour day.[br]Principal Honours and DistinctionsKnighted 1908. Baronet 1917.

6 World War II
(1939-1945)In the European phase of the war, neutral Portugal contributed more to the Allied victory than historians have acknowledged. Portugal experienced severe pressures to compromise her neutrality from both the Axis and Allied powers and, on several occasions, there were efforts to force Portugal to enter the war as a belligerent. Several factors lent Portugal importance as a neutral. This was especially the case during the period from the fall of France in June 1940 to the Allied invasion and reconquest of France from June to August 1944.In four respects, Portugal became briefly a modest strategic asset for the Allies and a war materiel supplier for both sides: the country's location in the southwesternmost corner of the largely German-occupied European continent; being a transport and communication terminus, observation post for spies, and crossroads between Europe, the Atlantic, the Americas, and Africa; Portugal's strategically located Atlantic islands, the Azores, Madeira, and Cape Verde archipelagos; and having important mines of wolfram or tungsten ore, crucial for the war industry for hardening steel.To maintain strict neutrality, the Estado Novo regime dominated by Antônio de Oliveira Salazar performed a delicate balancing act. Lisbon attempted to please and cater to the interests of both sets of belligerents, but only to the extent that the concessions granted would not threaten Portugal's security or its status as a neutral. On at least two occasions, Portugal's neutrality status was threatened. First, Germany briefly considered invading Portugal and Spain during 1940-41. A second occasion came in 1943 and 1944 as Great Britain, backed by the United States, pressured Portugal to grant war-related concessions that threatened Portugal's status of strict neutrality and would possibly bring Portugal into the war on the Allied side. Nazi Germany's plan ("Operation Felix") to invade the Iberian Peninsula from late 1940 into 1941 was never executed, but the Allies occupied and used several air and naval bases in Portugal's Azores Islands.The second major crisis for Portugal's neutrality came with increasing Allied pressures for concessions from the summer of 1943 to the summer of 1944. Led by Britain, Portugal's oldest ally, Portugal was pressured to grant access to air and naval bases in the Azores Islands. Such bases were necessary to assist the Allies in winning the Battle of the Atlantic, the naval war in which German U-boats continued to destroy Allied shipping. In October 1943, following tedious negotiations, British forces began to operate such bases and, in November 1944, American forces were allowed to enter the islands. Germany protested and made threats, but there was no German attack.Tensions rose again in the spring of 1944, when the Allies demanded that Lisbon cease exporting wolfram to Germany. Salazar grew agitated, considered resigning, and argued that Portugal had made a solemn promise to Germany that wolfram exports would be continued and that Portugal could not break its pledge. The Portuguese ambassador in London concluded that the shipping of wolfram to Germany was "the price of neutrality." Fearing that a still-dangerous Germany could still attack Portugal, Salazar ordered the banning of the mining, sale, and exports of wolfram not only to Germany but to the Allies as of 6 June 1944.Portugal did not enter the war as a belligerent, and its forces did not engage in combat, but some Portuguese experienced directly or indirectly the impact of fighting. Off Portugal or near her Atlantic islands, Portuguese naval personnel or commercial fishermen rescued at sea hundreds of victims of U-boat sinkings of Allied shipping in the Atlantic. German U-boats sank four or five Portuguese merchant vessels as well and, in 1944, a U-boat stopped, boarded, searched, and forced the evacuation of a Portuguese ocean liner, the Serpa Pinto, in mid-Atlantic. Filled with refugees, the liner was not sunk but several passengers lost their lives and the U-boat kidnapped two of the ship's passengers, Portuguese Americans of military age, and interned them in a prison camp. As for involvement in a theater of war, hundreds of inhabitants were killed and wounded in remote East Timor, a Portuguese colony near Indonesia, which was invaded, annexed, and ruled by Japanese forces between February 1942 and August 1945. In other incidents, scores of Allied military planes, out of fuel or damaged in air combat, crashed or were forced to land in neutral Portugal. Air personnel who did not survive such crashes were buried in Portuguese cemeteries or in the English Cemetery, Lisbon.Portugal's peripheral involvement in largely nonbelligerent aspects of the war accelerated social, economic, and political change in Portugal's urban society. It strengthened political opposition to the dictatorship among intellectual and working classes, and it obliged the regime to bolster political repression. The general economic and financial status of Portugal, too, underwent improvements since creditor Britain, in order to purchase wolfram, foods, and other materials needed during the war, became indebted to Portugal. When Britain repaid this debt after the war, Portugal was able to restore and expand its merchant fleet. Unlike most of Europe, ravaged by the worst war in human history, Portugal did not suffer heavy losses of human life, infrastructure, and property. Unlike even her neighbor Spain, badly shaken by its terrible Civil War (1936-39), Portugal's immediate postwar condition was more favorable, especially in urban areas, although deep-seated poverty remained.Portugal experienced other effects, especially during 1939-42, as there was an influx of about a million war refugees, an infestation of foreign spies and other secret agents from 60 secret intelligence services, and the residence of scores of international journalists who came to report the war from Lisbon. There was also the growth of war-related mining (especially wolfram and tin). Portugal's media eagerly reported the war and, by and large, despite government censorship, the Portuguese print media favored the Allied cause. Portugal's standard of living underwent some improvement, although price increases were unpopular.The silent invasion of several thousand foreign spies, in addition to the hiring of many Portuguese as informants and spies, had fascinating outcomes. "Spyland" Portugal, especially when Portugal was a key point for communicating with occupied Europe (1940-44), witnessed some unusual events, and spying for foreigners at least briefly became a national industry. Until mid-1944, when Allied forces invaded France, Portugal was the only secure entry point from across the Atlantic to Europe or to the British Isles, as well as the escape hatch for refugees, spies, defectors, and others fleeing occupied Europe or Vichy-controlled Morocco, Tunisia, and Algeria. Through Portugal by car, ship, train, or scheduled civil airliner one could travel to and from Spain or to Britain, or one could leave through Portugal, the westernmost continental country of Europe, to seek refuge across the Atlantic in the Americas.The wartime Portuguese scene was a colorful melange of illegal activities, including espionage, the black market, war propaganda, gambling, speculation, currency counterfeiting, diamond and wolfram smuggling, prostitution, and the drug and arms trade, and they were conducted by an unusual cast of characters. These included refugees, some of whom were spies, smugglers, diplomats, and business people, many from foreign countries seeking things they could find only in Portugal: information, affordable food, shelter, and security. German agents who contacted Allied sailors in the port of Lisbon sought to corrupt and neutralize these men and, if possible, recruit them as spies, and British intelligence countered this effort. Britain's MI-6 established a new kind of "safe house" to protect such Allied crews from German espionage and venereal disease infection, an approved and controlled house of prostitution in Lisbon's bairro alto district.Foreign observers and writers were impressed with the exotic, spy-ridden scene in Lisbon, as well as in Estoril on the Sun Coast (Costa do Sol), west of Lisbon harbor. What they observed appeared in noted autobiographical works and novels, some written during and some after the war. Among notable writers and journalists who visited or resided in wartime Portugal were Hungarian writer and former communist Arthur Koestler, on the run from the Nazi's Gestapo; American radio broadcaster-journalist Eric Sevareid; novelist and Hollywood script-writer Frederick Prokosch; American diplomat George Kennan; Rumanian cultural attache and later scholar of mythology Mircea Eliade; and British naval intelligence officer and novelist-to-be Ian Fleming. Other notable visiting British intelligence officers included novelist Graham Greene; secret Soviet agent in MI-6 and future defector to the Soviet Union Harold "Kim" Philby; and writer Malcolm Muggeridge. French letters were represented by French writer and airman, Antoine Saint-Exupery and French playwright, Jean Giroudoux. Finally, Aquilino Ribeiro, one of Portugal's premier contemporary novelists, wrote about wartime Portugal, including one sensational novel, Volframio, which portrayed the profound impact of the exploitation of the mineral wolfram on Portugal's poor, still backward society.In Estoril, Portugal, the idea for the world's most celebrated fictitious spy, James Bond, was probably first conceived by Ian Fleming. Fleming visited Portugal several times after 1939 on Naval Intelligence missions, and later he dreamed up the James Bond character and stories. Background for the early novels in the James Bond series was based in part on people and places Fleming observed in Portugal. A key location in Fleming's first James Bond novel, Casino Royale (1953) is the gambling Casino of Estoril. In addition, one aspect of the main plot, the notion that a spy could invent "secret" intelligence for personal profit, was observed as well by the British novelist and former MI-6 officer, while engaged in operations in wartime Portugal. Greene later used this information in his 1958 spy novel, Our Man in Havana, as he observed enemy agents who fabricated "secrets" for money.Thus, Portugal's World War II experiences introduced the country and her people to a host of new peoples, ideas, products, and influences that altered attitudes and quickened the pace of change in this quiet, largely tradition-bound, isolated country. The 1943-45 connections established during the Allied use of air and naval bases in Portugal's Azores Islands were a prelude to Portugal's postwar membership in the North Atlantic Treaty Organization (NATO). -

8 Charpy, Augustin Georges Albert
SUBJECT AREA: Metallurgy[br]b. 1 September 1865 Ouillins, Rhône, Franced. 25 November 1945 Paris, France[br]French metallurgist, originator of the Charpy pendulum impact method of testing metals.[br]After graduating in chemistry from the Ecole Polytechnique in 1887, Charpy continued to work there on the physical chemistry of solutions for his doctorate. He joined the Laboratoire d'Artillerie de la Marine in 1892 and began to study the structure and mechanical properties of various steels in relation to their previous heat treatment. His first memoir, on the mechanical properties of steels quenched from various temperatures, was published in 1892 on the advice of Henri Le Chatelier. He joined the Compagnie de Chatillon Commentry Fourchamboult et Decazeville at their steelworks in Imphy in 1898, shortly after the discovery of Invar by G.E. Guillaume. Most of the alloys required for this investigation had been prepared at Imphy, and their laboratories were therefore well equipped with sensitive and refined dilatometric facilities. Charpy and his colleague L.Grenet utilized this technique in many of their earlier investigations, which were largely concerned with the transformation points of steel. He began to study the magnetic characteristics of silicon steels in 1902, shortly after their use as transformer laminations had first been proposed by Hadfield and his colleagues in 1900. Charpy was the first to show that the magnetic hysteresis of these alloys decreased rapidly as their grain size increased.The first details of Charpy's pendulum impact testing machine were published in 1901, about two years before Izod read his paper to the British Association. As with Izod's machine, the energy of fracture was measured by the retardation of the pendulum. Charpy's test pieces, however, unlike those of Izod, were in the form of centrally notched beams, freely supported at each end against rigid anvils. This arrangement, it was believed, transmitted less energy to the frame of the machine and allowed the energy of fracture to be more accurately measured. In practice, however, the blow of the pendulum in the Charpy test caused visible distortion in the specimen as a whole. Both tests were still widely used in the 1990s.In 1920 Charpy left Imphy to become Director-General of the Compagnie des Aciéries de la Marine et Homecourt. After his election to the Académie des Sciences in 1918, he came to be associated with Floris Osmond and Henri Le Chatelier as one of the founders of the "French School of Physical Metallurgy". Around the turn of the century he had contributed much to the development of the metallurgical microscope and had helped to introduce the Chatelier thermocouple into the laboratory and to industry. He also popularized the use of platinum-wound resistance furnaces for laboratory purposes. After 1920 his industrial responsibilities increased greatly, although he continued to devote much of his time to teaching at the Ecole Supérieure des Mines in Paris, and at the Ecole Polytechnique. His first book, Leçons de Chimie (1892, Paris), was written at the beginning of his career, in association with H.Gautier. His last, Notions élémentaires de sidérurgie (1946, Paris), with P.Pingault as co-author, was published posthumously.[br]BibliographyCharpy published important metallurgical papers in Comptes rendus… Académie des Sciences, Paris.Further ReadingR.Barthélémy, 1947, "Notice sur la vie et l'oeuvre de Georges Charpy", Notices et discours, Académie des Sciences, Paris (June).M.Caullery, 1945, "Annonce du décès de M.G.

In 1844, he and his two brothers leased an iron blast-furnace at Wylam on Tyne. In 1850, with partners, he started chemical works at Washington, near Gateshead. A few years later, with his two brothers, he set up the Clarence Ironworks on Teesside. In the 1880s, salt extraction and soda-making were added there; at that time the Bell Brothers' enterprises, including collieries, employed 6,000 people.Lowthian Bell was a pioneer in applying thermochemistry to blast-furnace working. Besides his commercial interests, scientific experimentation and international travel, he found time to take a leading part in the promotion of British technical organizations; upon his death he left evidence of a prodigious level of personal activity.[br]Principal Honours and DistinctionsCreated baronet 1885.

10 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.
