Joseph Whitworth received his early education in a school kept by his father, but from the age of 12 he attended a school near Leeds. At 14 he joined his uncle's mill near Ambergate, Derbyshire, to learn the business of cotton spinning. In the four years he spent there he realized that he was more interested in the machinery than in managing a cotton mill. In 1821 he obtained employment as a mechanic with Crighton \& Co., Manchester. In 1825 he moved to London and worked for Henry Maudslay and later for the Holtzapffels and Joseph Clement. After these years spent gaining experience, he returned to Manchester in 1833 and set up in a small workshop under a sign "Joseph Whitworth, Tool Maker, from London".

The business expanded steadily and the firm made machine tools of all types and other engineering products including steam engines. From 1834 Whitworth obtained many patents in the fields of machine tools, textile and knitting machinery and road-sweeping machines. By 1851 the company was generally regarded as the leading manufacturer of machine tools in the country. Whitworth was a pioneer of precise measurement and demonstrated the fundamental mode of producing a true plane by making surface plates in sets of three. He advocated the use of the decimal system and made use of limit gauges, and he established a standard screw thread which was adopted as the national standard. In 1853 Whitworth visited America as a member of a Royal Commission and reported on American industry. At the time of the Crimean War in 1854 he was asked to provide machinery for manufacturing rifles and this led him to design an improved rifle of his own. Although tests in 1857 showed this to be much superior to all others, it was not adopted by the War Office. Whitworth's experiments with small arms led on to the construction of big guns and projectiles. To improve the quality of the steel used for these guns, he subjected the molten metal to pressure during its solidification, this fluid-compressed steel being then known as "Whitworth steel".

In 1868 Whitworth established thirty annual scholarships for engineering students. After his death his executors permanently endowed the Whitworth Scholarships and distributed his estate of nearly half a million pounds to various educational and charitable institutions. Whitworth was elected an Associate of the Institution of Civil Engineers in 1841 and a Member in 1848 and served on its Council for many years. He was elected a Member of the Institution of Mechanical Engineers in 1847, the year of its foundation.

Isaac Holden's father, who had the same name, had been a farmer and lead miner at Alston in Cumbria before moving to work in a coal-mine near Glasgow. After a short period at Kilbarchan grammar school, the younger Isaac was engaged first as a drawboy to two weavers and then, after the family had moved to Johnstone, Scotland, worked in a cotton-spinning mill while attending night school to improve his education. He was able to learn Latin and bookkeeping, but when he was about 15 he was apprenticed to an uncle as a shawl-weaver. This proved to be too much for his strength so he returned to scholastic studies and became Assistant to an able teacher, John Kennedy, who lectured on physics, chemistry and history, which he also taught to his colleague. The elder Isaac died in 1826 and the younger had to provide for his mother and younger brother, but in 1828, at the age of 21, he moved to a teaching post in Leeds. He filled similar positions in Huddersfield and Reading, where in October 1829 he invented and demonstrated the lucifer match but did not seek to exploit it. In 1830 he returned because of ill health to his mother in Scotland, where he began to teach again. However, he was recommended as a bookkeeper to William Townend, member of the firm of Townend Brothers, Cullingworth, near Bingley, Yorkshire. Holden moved there in November 1830 and was soon involved in running the mill, eventually becoming a partner.

In 1833 Holden urged Messrs Townend to introduce seven wool-combing machines of Collier's designs, but they were found to be very imperfect and brought only trouble and loss. In 1836 Holden began experimenting on the machines until they showed reasonable success. He decided to concentrate entirely on developing the combing machine and in 1846 moved to Bradford to form an alliance with Samuel Lister. A joint patent in 1847 covered improvements to the Collier combing machine. The "square motion" imitated the action of the hand-comber more closely and was patented in 1856. Five more patents followed in 1857 and others from 1858 to 1862. Holden recommended that the machines should be introduced into France, where they would be more valuable for the merino trade. This venture was begun in 1848 in the joint partnership of Lister \& Holden, with equal shares of profits. Holden established a mill at Saint-Denis, first with Donisthorpe machines and then with his own "square motion" type. Other mills were founded at Rheims and at Croix, near Roubaix. In 1858 Lister decided to retire from the French concerns and sold his share to Holden. Soon after this, Holden decided to remodel all their machinery for washing and carding the gill machines as well as perfecting the square comb. Four years of excessive application followed, during which time £20,000 was spent in experiments in a small mill at Bradford. The result fully justified the expenditure and the Alston Works was built in Bradford.

Holden was a Liberal and from 1865 to 1868 he represented Knaresborough in Parliament. Later he became the Member of Parliament for the Northern Division of the Riding, Yorkshire, and then for the town of Keighley after the constituencies had been altered. He was liberal in his support of religious, charitable and political objectives. His house at Oakworth, near Keighley, must have been one of the earliest to have been lit by electricity.

Samuel Fox was the son of a weaver's shuttle maker in the hamlet of Bradwell (probably Bradfield, near Sheffield) in the remote hills. He went to Sheffield and served an apprenticeship in the steel trade. Afterwards, he worked with great energy and industry until he acquired sufficient capital to start in business on his own account at Stocksbridge, near Sheffield. It was there that he invented what became known as "Fox's Paragon Frame" for umbrellas. Whalebone or solid steel had previously been used for umbrella ribs, but whalebone was unreliable and steel was heavy. Fox realized that if he grooved the ribs he could make them both lighter and more elastic. In his first patent, taken out in 1852, he described making the ribs and stretchers of parasols and umbrellas from a narrow strip of steel plate partially bent into a trough-like form. He took out five more patents. The first, in 1853, was for strengthening the joints. His next two, in 1856 and 1857, were more concerned with preparing the steel for making the ribs. Another patent in 1857 was basically for improving the formation of the bit at the end of the rib where it was fixed to the stretcher and where the end of the rib has to be formed into a boss: this was so it could have a pin fixed through it to act as a pivot when the umbrella has to be opened or folded and yet support the rib and stretcher. The final patent, in 1865, reverted once more to improving the manufacture of the ribs. He made a fortune before other manufacturers knew what he was doing. Fox established a works at Lille when he found that the French import duties and other fiscal arrangements hindered exporting umbrellas and successful trading there, and was thereby able to develop a large and lucrative business.

He early showed an aptitude for chemistry and in 1853 entered the Royal College of Chemistry as a student under A.W.von Hofmann, the first Professor at the College. By the end of his first year, he had carried out his first piece of chemical research, on the action of cyanogen chloride on phenylamine, which he published in the Journal of the Chemical Society (1857). He became honorary assistant to von Hofmann in 1857; three years previously he had set up his own chemical laboratory at home, where he had discovered the first of the azo dyes, aminoazonapththalene. In 1856 Perkin began work on the synthesis of quinine by oxidizing a salt of allyl toluidine with potassium dichromate. Substituting aniline, he obtained a dark-coloured precipitate which proved to possess dyeing properties: Perkin had discovered the first aniline dye. Upon receiving favourable reports on the new material from manufacturers of dyestuffs, especially Pullars of Perth, Perkin resigned from the College and turned to the commercial exploitation of his discovery. This proved highly successful. From 1858, the dye was manufactured at his Greenford Green works as "Aniline Purple" or "Tyrian Purple". It was later to be referred to by the French as mauve. Perkin's discovery led to the development of the modern dyestuffs industry, supplanting dyes from the traditional vegetable sources. In 1869, he introduced two new methods for making the red dye alizarin, in place of the process that involved the use of the madder plant (Rubia tinctorum). In spite of German competition, he dominated the British market until the end of 1873. After eighteen years in chemical industry, Perkin retired and devoted himself entirely to the pure chemical research which he had been pursuing since the 1850s. He eventually contributed ninety papers to the Chemical Society and further papers to other bodies, including the Royal Society. For example, in 1867 he published his synthesis of unsaturated organic acids, known as "Perkin's synthesis". Other papers followed, on the structure of "Aniline Purple". In 1881 Perkin drew attention to the magnetic-rotatory power of some of the substances he had been dealing with. From then on, he devoted particular attention to the application of this phenomenon to the determination of chemical structure.

Perkin won wide recognition for his discoveries and other contributions to chemistry.

The half-centenary of his great discovery was celebrated in July 1906 and later that year he received a knighthood.

At the age of 15 Field left home to seek his fortune in New York, starting work on Broadway as an errand boy for $1 per week. Returning to Massachusetts, in 1838 he became an assistant to his brother Matthew, a paper-maker, leaving to set up his own business two years later. By the age of 21 he was also a partner in a New York firm of paper wholesalers, but this firm collapsed because of large debts. Out of the wreckage he set up Cyrus W.Field \& Co., and by 1852 he had paid off all the debts. With $250,000 in the bank he therefore retired and travelled in South America. Returning to the USA, he then became involved with the construction of a telegraph line in Newfoundland by an English engineer, F.N. Osborne. Although the company collapsed, he had been fired by the dream of a transatlantic cable and in 1854 was one of the founders of the New York, Newfoundland and London Telegraph Company. He began to promote surveys and hold discussions with British telegraph pioneers and with Isambard Brunel, who was then building the Great Eastern steamship. In 1856 he helped to set up the Atlantic Telegraph Company in Britain and, as a result of his efforts and those of the British physicist and inventor Sir William Thomson (Lord Kelvin), work began in 1857 on the laying of the first transatlantic cable from Newfoundland to Ireland. After many tribulations the cable was completed on 5 August 1857, but it failed after barely a month. Following several unsuccessful attempts to repair and replace it, the cable was finally completed on 27 July 1866. Building upon his success, Field expanded his business interests. In 1877 he bought a controlling interest in and was President of the New York Elevated Railroad Company. He also helped develop the Wabash Railroad and became owner of the New York Mail and Express newspaper; however, he subsequently suffered large financial losses.

Robert Wilson was the son of a fisherman who was drowned in a lifeboat rescue attempt in December 1810. He received only a meagre education and was apprenticed to a joiner. From a very early age he was much concerned with the idea of applying screw propellers to ships, and his invention was approved by the Highland Society and by the Scottish Society of Arts, who in 1832 awarded him a silver medal. He must have gained some experience as a mechanic and while working on his invention he made the acquaintance of James Nasmyth. In 1838 he became Works Manager at Nasmyth's Bridgewater Foundry and made an important contribution to the success of the steam-hammer by developing the self-acting control gear. From 1845 he was with the Low Moor Ironworks near Bradford, Yorkshire, but in July 1856 he returned to the Bridgewater Foundry so that he was able to take over as Managing Partner after Nasmyth's early retirement at the end of 1856. In 1867 the name of the firm was changed to Nasmyth, Wilson \& Co., and Wilson remained a partner until May 1882, when the firm became a limited company. Wilson often returned to his first invention, and two of his many patents related to improvements in screw propellers. In 1880 he received £500 from the War Department for the use of his double-action screw propeller as applied to the torpedo.

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.

James Harrison emigrated to Australia in 1834, and in 1840 settled in Geelong as a journalist. At one time he was editor of the Melbourne Age. In 1850 he began to devote his attention to the development of an ice-making scheme, erecting the first factory at Rodey Point, Barwin, in that year. In 1851 the Brewery Glasgow \& Co. in Bendigo, Victoria, installed the first Harrison refrigerator. He took out patents for his invention in 1856 and 1857, and visited London at about the same time. On his return to Australia he began experiments into the long-term freezing of meat. In 1873 he publicly exhibited the process in Melbourne and organized a banquet for the consumption of meat which had been in store for six months. In July of the same year the SS Norfolk sailed with a cargo of 20 tons of frozen mutton and beef, but this began to rot en route to London. The refrigeration plant was later put to use in a paraffin factory in London, but the failure ruined Harrison and took all his newspaper profits.

Pihl trained as an engineer at Göteborg, Sweden, and then moved to London, where he worked under Robert Stephenson during 1845 and 1846. In 1850 he returned to Norway and worked with the English contractors building the first railway in Norway, the Norwegian Trunk Railway from Kristiania to Eidsvold, for which the English standard gauge was used. Subsequently he worked in England for a year, but in 1856 joined the Norwegian government's Road Department, which was to have responsibility for railways. In 1865 a distinct Railway Department was set up, and Pihl became Director for State Railway Construction. Because of the difficulties of the terrain and limited traffic, Pihl recommended that in the case of two isolated lines to be built the outlay involved in ordinary railways would not be justified, and that they should be built to the narrow gauge of 3 ft 6 in. (1.07 m). His recommendation was accepted by the Government in 1857 and the two lines were built to this gauge and opened during 1861–4. Six of their seven locomotives, and all their rolling stock, were imported from Britain. The lines cost £3,000 and £5,000 per mile, respectively; a standard-gauge line built in the same period cost £6,400 per mile.

Subsequently, many hundreds of miles of Norwegian railways were built to 3 ft 6 in. (1.07 m) gauge under Pihl's direction. They influenced construction of railways to this gauge in Australia, Southern Africa, New Zealand, Japan and elsewhere. However, in the late 1870s controversy arose in Norway over the economies that could in fact be gained from the 3 ft 6 in. (1,07 m) gauge. This controversy in the press, in discussion and in the Norwegian parliament became increasingly acrimonious during the next two decades; the standard-gauge party may be said to have won with the decision in 1898, the year after Pihl's death, to build the Bergen-Oslo line to standard gauge.

Ramsbottom's initial experience was gained at the locomotive manufacturers Sharp, Roberts \& Co. At the age of 28 he was Manager of the Longsight works of the Manchester \& Birmingham Railway, which, with other lines, became part of the London \& North Western Railway (L \& NWR) in 1846. Ramsbottom was appointed Locomotive Superintendent of its north-eastern division. Soon after 1850 came his first major invention, that of the split-ring piston, consisting of castiron rings fitted round the piston to ensure a steam-tight fit in the cylinder. This proved to be successful, with a worldwide application. In 1856 he introduced sight-feed lubrication and the form of safety valve that bears his name. In 1857 he became Locomotive Superintendent of the L \& NWR at Crewe, producing two notable classes of locomotives: 2–4–0s for passenger traffic; and 0–6–0s for goods. They were of straightforward design and robust construction, and ran successfully for many years. His most spectacular railway invention was the water trough between the rails which enabled locomotives to replenish their water tanks without stopping.

As part of his policy of making Crewe works as independent as possible, Ramsbottom made several metallurgical innovations. He installed one of the earliest Bessemer converters for steelmaking. More important, in 1866 he coupled the engine part of a railway engine to a two-high rolling mill so that the rolls could be run in either direction, and quickly change direction, by means of the standard railway link reversing gear. This greatly speeded up the rolling of iron or steel into the required sections. He eventually retired in 1871.

Born Carl Wilhelm, he attended craft schools in Lübeck and Magdeburg, followed by an intensive course in natural science at Göttingen as a pupil of Weber. At the age of 19 Siemens travelled to England and sold an electroplating process developed by his brother Werner Siemens to Richard Elkington, who was already established in the plating business. From 1843 to 1844 he obtained practical experience in the Magdeburg works of Count Stolburg. He settled in England in 1844 and later assumed British nationality, but maintained close contact with his brother Werner, who in 1847 had co-founded the firm Siemens \& Halske in Berlin to manufacture telegraphic equipment. William began to develop his regenerative principle of waste-heat recovery and in 1856 his brother Frederick (1826–1904) took out a British patent for heat regeneration, by which hot waste gases were passed through a honeycomb of fire-bricks. When they became hot, the gases were switched to a second mass of fire-bricks and incoming air and fuel gas were led through the hot bricks. By alternating the two gas flows, high temperatures could be reached and considerable fuel economies achieved. By 1861 the two brothers had incorporated producer gas fuel, made by gasifying low-grade coal.

Heat regeneration was first applied in ironmaking by Cowper in 1857 for heating the air blast in blast furnaces. The first regenerative furnace was set up in Birmingham in 1860 for glassmaking. The first such furnace for making steel was developed in France by Pierre Martin and his father, Emile, in 1863. Siemens found British steelmakers reluctant to adopt the principle so in 1866 he rented a small works in Birmingham to develop his open-hearth steelmaking furnace, which he patented the following year. The process gradually made headway; as well as achieving high temperatures and saving fuel, it was slower than Bessemer's process, permitting greater control over the content of the steel. By 1900 the tonnage of open-hearth steel exceeded that produced by the Bessemer process.

In 1872 Siemens played a major part in founding the Society of Telegraph Engineers (from which the Institution of Electrical Engineers evolved), serving as its first President. He became President for the second time in 1878. He built a cable works at Charlton, London, where the cable could be loaded directly into the holds of ships moored on the Thames. In 1873, together with William Froude, a British shipbuilder, he designed the Faraday, the first specialized vessel for Atlantic cable laying. The successful laying of a cable from Europe to the United States was completed in 1875, and a further five transatlantic cables were laid by the Faraday over the following decade.

The Siemens factory in Charlton also supplied equipment for some of the earliest electric-lighting installations in London, including the British Museum in 1879 and the Savoy Theatre in 1882, the first theatre in Britain to be fully illuminated by electricity. The pioneer electric-tramway system of 1883 at Portrush, Northern Ireland, was an opportunity for the Siemens company to demonstrate its equipment.

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.

James Thomson was a pupil in several civil-engineering offices, but the nature of the work was beyond his physical capacity and from 1843 onwards he devoted himself to theoretical studies. Hhe first concentrated on the problems associated with the expansion of liquids when they reach their freezing point: water is one such example. He continued this work with his younger brother, Lord Kelvin (see Thomson, Sir William).

After experimentation with a "feathered" paddle wheel as a young man, he turned his attention to water power. In 1850 he made his first patent application, "Hydraulic machinery and steam engines": this patent became his "Vortex" turbine design. He settled in Belfast, the home of the MacAdam-Fourneyron turbine, in 1851, and as a civil engineer became the Resident Engineer to the Belfast Water Commissioners in 1853. In 1857 he was appointed Professor of Civil Engineering and Surveying at Queen's College, Belfast.

Whilst it is understood that he made his first turbine models in Belfast, he came to an arrangement with the Williamson Brothers of Kendal to make his turbine. In 1856 Williamsons produced their first turbine to Thomson's design and drawings. This was the Vortex Williamson Number 1, which produced 5 hp (3.7 kW) under a fall of 31 ft (9.4 m) on a 9 in. (23 cm) diameter supply. The rotor of this turbine ran in a horizontal plane. For several years the Williamson catalogue described their Vortex turbine as "designed by Professor James Thomson".

Thomson continued with his study of hydraulics and water flow both at Queen's College, Belfast, and, later, at Glasgow University, where he became Professor in 1873, succeeding Macquorn Rankine, another famous engineer. At Glasgow, James Thomson studied the flow in rivers and the effects of erosion on river beds. He was also an authority on geological formations such as the development of the basalt structure of the Giant's Causeway, north of Belfast.

James Thomson was an extremely active engineer and a very profound teacher of civil engineering. His form of water turbine had a long life before being displaced by the turbines designed in the twentieth century.

After education at Glasgow University and Peterhouse, Cambridge, a period of study in France gave Thomson an interest in experimental work and instrumentation. He became Professor of Natural Philosophy at Glasgow in 1846 and retained the position for the rest of his career, establishing the first teaching laboratory in Britain.

Among his many contributions to science and engineering was his concept, introduced in 1848, of an "absolute" zero of temperature. Following on from the work of Joule, his investigations into the nature of heat led to the first successful liquefaction of gases such as hydrogen and helium, and later to the science of low-temperature physics.

Cable telegraphy gave an impetus to the scientific measurement of electrical quantities, and for many years Thomson was a member of the British Association Committee formed in 1861 to consider electrical standards and to develop units; these are still in use. Thomson first became Scientific Adviser to the Atlantic Telegraph Company in 1857, sailing on the Agamemnon and Great Eastern during the cable-laying expeditions. He invented a mirror galvanometer and more importantly the siphon recorder, which, used as a very sensitive telegraph receiver, provided a permanent record of signals. He also laid down the design parameters of long submarine cables and discovered that the conductivity of copper was greatly affected by its purity. A major part of the success of the Atlantic cable in 1866 was due to Thomson, who received a knighthood for his contribution.

Other instruments he designed included a quadrant electrostatic voltmeter to measure high voltages, and his "multi-cellular" instrument for low voltages. They could be used on alternating or direct current and were free from temperature errors. His balances for precision current measurement were widely used in standardizing laboratories.

Thomson was a prolific writer of scientific papers on subjects across the whole spectrum of physics; between 1855 and 1866 he published some 110 papers, with a total during his life of over 600. In 1892 he was raised to the peerage as Baron Kelvin of Largs. By the time of his death he was looked upon as the "father" of British physics, but despite his outstanding achievements his later years were spent resisting change and progress.
