His family emigrated to Australia when he was 5 years old. He was educated at Wesley College, Melbourne, and attended Queen's College, University of Melbourne, graduating in physics and engineering in 1897. As an 1851 Exhibitioner he then spent three years at St John's College, Cambridge, under Sir Alfred Ewing, where he studied the microstructure of deformed metal crystals and abandoned his original intention of becoming a civil engineer. Rosenhain was the first to observe the slip-bands in metal crystals, and in the Bakerian Lecture delivered jointly by Ewing and Rosenhain to the Royal Society in 1899 it was shown that metals deformed plastically by a mechanism involving shear slip along individual crystal planes. From this conception modern ideas on the plasticity and recrystallization of metals rapidly developed. On leaving Cambridge, Rosenhain joined the Birmingham firm of Chance Brothers, where he worked for six years on optical glass and lighthouse-lens systems. A book, Glass Manufacture, written in 1908, derives from this period, during which he continued his metallurgical researches in the evenings in his home laboratory and published several papers on his work.

In 1906 Rosenhain was appointed Head of the Metallurgical Department of the National Physical Laboratory (NPL), and in 1908 he became the first Superintendent of the new Department of Metallurgy and Metallurgical Chemistry. Many of the techniques he introduced at Teddington were described in his Introduction to Physical Metallurgy, published in 1914. At the outbreak of the First World War, Rosenhain was asked to undertake work in his department on the manufacture of optical glass. This soon made it possible to manufacture optical glass of high quality on an industrial scale in Britain. Much valuable work on refractory materials stemmed from this venture. Rosenhain's early years at the NPL were, however, inseparably linked with his work on light alloys, which between 1912 and the end of the war involved virtually all of the metallurgical staff of the laboratory. The most important end product was the well-known "Y" Alloy (4% copper, 2% nickel and 1.5% magnesium) extensively used for the pistons and cylinder heads of aircraft engines. It was the prototype of the RR series of alloys jointly developed by Rolls Royce and High Duty Alloys. An improved zinc-based die-casting alloy devised by Rosenhain was also used during the war on a large scale for the production of shell fuses.

After the First World War, much attention was devoted to beryllium, which because of its strength, lightness, and stiffness would, it was hoped, become the airframe material of the future. It remained, however, too brittle for practical use. Other investigations dealt with impurities in copper, gases in aluminium alloys, dental alloys, and the constitution of alloys. During this period, Rosenhain's laboratory became internationally known as a centre of excellence for the determination of accurate equilibrium diagrams.

A descendant of Nuremberg nobility, Ebener became recognized as a statesman in his native city and was employed also by foreign dignitaries. His appointment as Privy Councillor to the Dukes of Brunswick involved him in mining and metallurgical affairs at the great Rammelsberg mixed-ore mine at Goslar in the Harz mountains. About 1550, at Rammelsberg, Ebener is believed to have made brass by incorporating accretions of zinc formed in crevices of local lead-smelting furnaces. This small-scale production of impure zinc, formerly discarded as waste, could be used to replace calamine, the carbonate ore of zinc, which by tradition had been combined with copper in European brassmaking. Ercker, writing in 1574, mentions the accretions at Goslar obtained by removing furnace sections to make this material available for brass. The true nature of the zinc ore, calamine, and zinc metal compared with these accretions was determined only much later, but variation in quality with respect to impurities made the material most suitable for cast brassware rather than beaten goods. As quantities were small and much valued, distribution from Goslar was limited, not normally reaching Britain, where production of brasses continued to rely on calamine or expensive zinc imports from the East. Rammelsberg profited from the waste material accumulating over the years and its use at Bundheim brassworks east of Goslar. Ebener partnered Duke Henry the Younger of Brunswick in financing a new drainage adit at Rammelsberg, and was later granted several iron mines and smelting works. From 1556 he was granted rights to market calamine from the Lower Harz and copper sulphate from Rammelsberg. Ebener later had an important role at the court of Duke Julius, son of Henry, advising him on the founding of Helmstedt University.

Desiring to celebrate a sacrifice by virtue of which he could go up to heaven in his mortal body, he requested his family-priest Vasiṣṭha to officiate for him; but being refused he next requested his hundred sons who also rejected his absurd proposal. He, therefore, called them cowardly and impotent, and was, in return for these insults, cursed and degraded by them to be a Chāṇḍāla. While he was in this wretched condition, Viśvāmitra, whose family Triśaṅku had in times of famine laid under deep obligations, undertook to celebrate the sacrifice, and invited all the gods to be present. They, however, declined; whereupon the enraged Viśvāmitra. by his own power lifted up Triśaṅku to the skies with his cherished mortal body. He began to soar higher and higher till his head struck against the vault of the heaven, when he was hurled down head-foremost by Indra and the other gods. The mighty Viśvāmitra, however, arrested him in his downward course, saying 'Stay Triśaṅku', and the unfortunate monarch remained suspended with his head towards the earth as a constellation in the southern hemisphere. Hence the wellknown proverb:-- त्रिशङ्कुरिवान्तरा तिष्ठ Ś.2.]

He was the son of Captain Cowper- Coles, Royal Navy, the inventor of the swivelling turret for naval guns. He inherited his father's inventive talents and investigated a variety of inventions in his workshop at his home at Sunbury-on-Thames, assisted by a number of scientific workers. He had been educated by governesses, but he lacked a sound scientific background. His inventions, rarely systematically pursued, ranged from electrolytic processes for making copper sheets and parabolic reflectors to a process for inlaying and decorating metallic surfaces. Overall, however, he is best known for the invention of "sherardizing", the process for producing a rustproof coating of zinc on small metallic articles. The discovery came by chance, when he was annealing iron and steel packed in zinc dust to exclude air. The metal was found to be coated with a thin layer of zinc with some surface penetration. The first patent for the process was obtained in 1900, and later the American rights were sold, with a company being formed in 1908 to control them. A small plant was set up in Chelsea, London, to develop the process to the point where it could be carried out on a commercial scale in a plant in Willesden. Sherardizing has not been a general protective finish, but is restricted to articles such as nuts and bolts which are then painted or finished. The process was still in use in 1977, operated by the Zinc Alloy Company (London) Ltd.

(and Enclave of Cabinda)

   From 1575 to 1975, Angola was a colony of Portugal. Located in west-central Africa, this colony has been one of the largest, most strategically located, and richest in mineral and agricultural resources in the continent. At first, Portugal's colonial impact was largely coastal, but after 1700 it became more active in the interior. By international treaties signed between 1885 and 1906, Angola's frontiers with what are now Zaire and Zambia were established. The colony's area was 1,246,700 square kilometers (481,000 square miles), Portugal's largest colonial territory after the independence of Brazil. In Portugal's third empire, Angola was the colony with the greatest potential.

   The Atlantic slave trade had a massive impact on the history, society, economy, and demography of Angola. For centuries, Angola's population played a subordinate role in the economy of Portugal's Brazil-centered empire. Angola's population losses to the slave trade were among the highest in Africa, and its economy became, to a large extent, hostage to the Brazilian plantation-based economic system. Even after Brazil's independence in 1822, Brazilian economic interests and capitalists were influential in Angola; it was only after Brazil banned the slave trade in 1850 that the heavy slave traffic to former Portuguese America began to wind down. Although slavery in Angola was abolished, in theory, in the 1870s, it continued in various forms, and it was not until the early 1960s that its offspring, forced labor, was finally ended.

   Portugal's economic exploitation of Angola went through different stages. During the era of the Atlantic slave trade (ca. 1575-1850), when many of Angola's slaves were shipped to Brazil, Angola's economy was subordinated to Brazil's and to Portugal's. Ambitious Lisbon-inspired projects followed when Portugal attempted to replace the illegal slave trade, long the principal income source for the government of Angola, with legitimate trade, mining, and agriculture. The main exports were dyes, copper, rubber, coffee, cotton, and sisal. In the 1940s and 1950s, petroleum emerged as an export with real potential. Due to the demand of the World War II belligerents for Angola's raw materials, the economy experienced an impetus, and soon other articles such as diamonds, iron ore, and manganese found new customers. Angola's economy, on an unprecedented scale, showed significant development, which was encouraged by Lisbon. Portugal's colonization schemes, sending white settlers to farm in Angola, began in earnest after 1945, although such plans had been nearly a century in the making. Angola's white population grew from about 40,000 in 1940 to nearly 330,000 settlers in 1974, when the military coup occurred in Portugal.

   In the early months of 1961, a war of African insurgency broke out in northern Angola. Portugal dispatched armed forces to suppress resistance, and the African insurgents were confined to areas on the borders of northern and eastern Angola at least until the 1966-67 period. The 13-year colonial war had a telling impact on both Angola and Portugal. When the Armed Forces Movement overthrew the Estado Novo on 25 April 1974, the war in Angola had reached a stalemate and the major African nationalist parties (MPLA, FNLA, and UNITA) had made only modest inroads in the northern fringes and in central and eastern Angola, while there was no armed activity in the main cities and towns.

   After a truce was called between Portugal and the three African parties, negotiations began to organize the decolonizat ion process. Despite difficult maneuvering among the parties, Portugal, the MPLA, FNLA, and UNITA signed the Alvor Agreement of January 1975, whereby Portugal would oversee a transition government, create an all-Angola army, and supervise national elections to be held in November 1975. With the outbreak of a bloody civil war among the three African parties and their armies, the Alvor Agreement could not be put into effect. Fighting raged between March and November 1975. Unable to prevent the civil war or to insist that free elections be held, Portugal's officials and armed forces withdrew on 11 November 1975. Rather than handing over power to one party, they transmitted sovereignty to the people of Angola. Angola's civil war continued into the 21st century.

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.

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.

In November 1770, John Mackenzie, owner of a bleaching mill, took his millwright Thomas Bell to Glasgow to consult with James Watt about problems they were having with the calico printing machine invented by Bell some years previously. Bell rolled sheets of copper one eighth of an inch (3 mm) thick into cyliders, and filled them with cement which was held in place by cast iron ends. After being turned true and polished, the cylinders were engraved; they cost about £10 each. The printing machines were driven by a water-wheel, but Bell and Mackenzie appeared to have had problems with the doctor blades which scraped off excess colour, and this may have been why they visited Watt.

They had, presumably, solved the technical problems when Bell took out a patent in 1783 which describes him as "the Elder", but there are no further details about the man himself. The machine is described as having six printing rollers arranged around the top of the circumference of a large central bowl. In later machines, the printing rollers were placed all round a smaller cylinder. All of the printing rollers, each printing a different colour, were driven by gearing to keep them in register. The patent includes steel doctor blades which would have scraped excess colour off the printing rollers. Another patent, taken out in 1784, shows a smaller three-colour machine. The printing rollers had an iron core covered with copper, which could be taken off at pleasure so that fresh patterns could be cut as desired. Bell's machine was used at Masney, near Preston, England, by Messrs Livesey, Hargreaves, Hall \& Co in 1786. Although copper cylinders were difficult to make and engrave, and the soldered seams often burst, these machines were able to increase the output of the cheaper types of printed cloth.

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.

The son of Marc Isambard Brunel and Sophia Kingdom, he was educated at a private boarding-school in Hove. At the age of 14 he went to the College of Caen and then to the Lycée Henri-Quatre in Paris, after which he was apprenticed to Louis Breguet. In 1822 he returned from France and started working in his father's office, while spending much of his time at the works of Maudslay, Sons \& Field.

From 1825 to 1828 he worked under his father on the construction of the latter's Thames Tunnel, occupying the position of Engineer-in-Charge, exhibiting great courage and presence of mind in the emergencies which occurred not infrequently. These culminated in January 1828 in the flooding of the tunnel and work was suspended for seven years. For the next five years the young engineer made abortive attempts to find a suitable outlet for his talents, but to little avail. Eventually, in 1831, his design for a suspension bridge over the River Avon at Clifton Gorge was accepted and he was appointed Engineer. (The bridge was eventually finished five years after Brunel's death, as a memorial to him, the delay being due to inadequate financing.) He next planned and supervised improvements to the Bristol docks. In March 1833 he was appointed Engineer of the Bristol Railway, later called the Great Western Railway. He immediately started to survey the route between London and Bristol that was completed by late August that year. On 5 July 1836 he married Mary Horsley and settled into 18 Duke Street, Westminster, London, where he also had his office. Work on the Bristol Railway started in 1836. The foundation stone of the Clifton Suspension Bridge was laid the same year. Whereas George Stephenson had based his standard railway gauge as 4 ft 8½ in (1.44 m), that or a similar gauge being usual for colliery wagonways in the Newcastle area, Brunel adopted the broader gauge of 7 ft (2.13 m). The first stretch of the line, from Paddington to Maidenhead, was opened to traffic on 4 June 1838, and the whole line from London to Bristol was opened in June 1841. The continuation of the line through to Exeter was completed and opened on 1 May 1844. The normal time for the 194-mile (312 km) run from Paddington to Exeter was 5 hours, at an average speed of 38.8 mph (62.4 km/h) including stops. The Great Western line included the Box Tunnel, the longest tunnel to that date at nearly two miles (3.2 km).

Brunel was the engineer of most of the railways in the West Country, in South Wales and much of Southern Ireland. As railway networks developed, the frequent break of gauge became more of a problem and on 9 July 1845 a Royal Commission was appointed to look into it. In spite of comparative tests, run between Paddington-Didcot and Darlington-York, which showed in favour of Brunel's arrangement, the enquiry ruled in favour of the narrow gauge, 274 miles (441 km) of the former having been built against 1,901 miles (3,059 km) of the latter to that date. The Gauge Act of 1846 forbade the building of any further railways in Britain to any gauge other than 4 ft 8 1/2 in (1.44 m).

The existence of long and severe gradients on the South Devon Railway led to Brunel's adoption of the atmospheric railway developed by Samuel Clegg and later by the Samuda brothers. In this a pipe of 9 in. (23 cm) or more in diameter was laid between the rails, along the top of which ran a continuous hinged flap of leather backed with iron. At intervals of about 3 miles (4.8 km) were pumping stations to exhaust the pipe. Much trouble was experienced with the flap valve and its lubrication—freezing of the leather in winter, the lubricant being sucked into the pipe or eaten by rats at other times—and the experiment was abandoned at considerable cost.

Brunel is to be remembered for his two great West Country tubular bridges, the Chepstow and the Tamar Bridge at Saltash, with the latter opened in May 1859, having two main spans of 465 ft (142 m) and a central pier extending 80 ft (24 m) below high water mark and allowing 100 ft (30 m) of headroom above the same. His timber viaducts throughout Devon and Cornwall became a feature of the landscape. The line was extended ultimately to Penzance.

As early as 1835 Brunel had the idea of extending the line westwards across the Atlantic from Bristol to New York by means of a steamship. In 1836 building commenced and the hull left Bristol in July 1837 for fitting out at Wapping. On 31 March 1838 the ship left again for Bristol but the boiler lagging caught fire and Brunel was injured in the subsequent confusion. On 8 April the ship set sail for New York (under steam), its rival, the 703-ton Sirius, having left four days earlier. The 1,340-ton Great Western arrived only a few hours after the Sirius. The hull was of wood, and was copper-sheathed. In 1838 Brunel planned a larger ship, some 3,000 tons, the Great Britain, which was to have an iron hull.

The Great Britain was screwdriven and was launched on 19 July 1843,289 ft (88 m) long by 51 ft (15.5 m) at its widest. The ship's first voyage, from Liverpool to New York, began on 26 August 1845. In 1846 it ran aground in Dundrum Bay, County Down, and was later sold for use on the Australian run, on which it sailed no fewer than thirty-two times in twenty-three years, also serving as a troop-ship in the Crimean War. During this war, Brunel designed a 1,000-bed hospital which was shipped out to Renkioi ready for assembly and complete with shower-baths and vapour-baths with printed instructions on how to use them, beds and bedding and water closets with a supply of toilet paper! Brunel's last, largest and most extravagantly conceived ship was the Great Leviathan, eventually named The Great Eastern, which had a double-skinned iron hull, together with both paddles and screw propeller. Brunel designed the ship to carry sufficient coal for the round trip to Australia without refuelling, thus saving the need for and the cost of bunkering, as there were then few bunkering ports throughout the world. The ship's construction was started by John Scott Russell in his yard at Millwall on the Thames, but the building was completed by Brunel due to Russell's bankruptcy in 1856. The hull of the huge vessel was laid down so as to be launched sideways into the river and then to be floated on the tide. Brunel's plan for hydraulic launching gear had been turned down by the directors on the grounds of cost, an economy that proved false in the event. The sideways launch with over 4,000 tons of hydraulic power together with steam winches and floating tugs on the river took over two months, from 3 November 1857 until 13 January 1858. The ship was 680 ft (207 m) long, 83 ft (25 m) beam and 58 ft (18 m) deep; the screw was 24 ft (7.3 m) in diameter and paddles 60 ft (18.3 m) in diameter. Its displacement was 32,000 tons (32,500 tonnes).

The strain of overwork and the huge responsibilities that lay on Brunel began to tell. He was diagnosed as suffering from Bright's disease, or nephritis, and spent the winter travelling in the Mediterranean and Egypt, returning to England in May 1859. On 5 September he suffered a stroke which left him partially paralysed, and he died ten days later at his Duke Street home.

After private education and an engineering apprenticeship, Crampton worked under Marc Brunel, Daniel Gooch and the Rennie brothers before setting up as a civil engineer in 1848. His developing ideas on locomotive design were expressed through a series of five patents taken out between 1842 and 1849, each making a multiplicity of claims. The most typical feature of the Crampton locomotive, however, was a single pair of driving wheels set to the rear of the firebox. This meant they could be of large diameter, while the centre of gravity of the locomotive remained low, for the boiler barrel, though large, had only small carrying-wheels beneath it. The cylinders were approximately midway along the boiler and were outside the frames, as was the valve gear. The result was a steady-riding locomotive which neither pitched about a central driving axle nor hunted from side to side, as did other contemporary locomotives, and its working parts were unusually accessible for maintenance. However, adhesive weight was limited and the long wheelbase tended to damage track. Locomotives of this type were soon superseded on British railways, although they lasted much longer in Germany and France. Locomotives built to the later patents incorporated a long, coupled wheelbase with drive through an intermediate crankshaft, but they mostly had only short lives. In 1851 Crampton, with associates, laid the first successful submarine electric telegraph cable. The previous year the brothers Jacob and John Brett had laid a cable, comprising a copper wire insulated with gutta-percha, beneath the English Channel from Dover to Cap Gris Nez: signals were passed but within a few hours the cable failed. Crampton joined the Bretts' company, put up half the capital needed for another attempt, and designed a much stronger cable. Four gutta-percha-insulated copper wires were twisted together, surrounded by tarred hemp and armoured by galvanized iron wires; this cable was successful.

Crampton was also active in railway civil engineering and in water and gas engineering, and c. 1882 he invented a hydraulic tunnel-boring machine intended for a Channel tunnel.
