England began his distinguished photographic career taking daguerreotype portraits in London in the 1840s. In 1854 he joined the London Stereoscopic Company and became its chief photographer, taking thousands of stereoscopic views all over the world. In 1859 he travelled to America to take views of the Niagara Falls. On returning to Britain he became a freelance photographer, adding to his considerable reputation with a long series of stereoscopic alpine views. He also became interested in panoramic photography and, later, photolithography. England's most important technical innovation was a drop shutter with a horizontal slit sited immediately in front of the plate. Proposed in 1861, this was a crude device, but is usually recognized as the precursor of the modern focal-plane shutter.

William Hesketh Lever was the son of the retail grocer James Lever, who built up the large wholesale firm of Lever \& Co. in the north-west of England. William entered the firm at the age of 19 as a commercial traveller, and in the course of his work studied the techniques of manufacture and the quality of commercial soaps available at the time. He decided that he would concentrate on the production of a soap that was not evil-smelling, would lather easily and be attractively packaged. In 1884 he produced Sunlight Soap, which became the trade mark for Lever \& Co. He had each tablet wrapped, partly to protect the soap from oxygenization and thus prevent it from becoming rancid, and partly to display his brand name as a form of advertising. In 1885 he raised a large capital sum, purchased the Soap Factory in Warrington of Winser \& Co., and began manufacture. His product contained oils from copra, palm and cotton blended with tallow and resin, and its quality was carefully monitored during production. In a short time it was in great demand and began to replace the previously available alternatives of home-made soap and poor-quality, unpleasant-smelling bars.

It soon became necessary to expand the firm's premises, and in 1887 Lever purchased fifty-six acres of land upon which he set up a new centre of manufacture. This was in the Wirral in Cheshire, near the banks of the River Mersey. Production at the new factory, which was called Port Sunlight, began in January 1889. Lever introduced a number of technical improvements in the production process, including the heating systems and the recovery of glycerine (which could later be sold) from the boiling process.

Like Sir Titus Salt of Saltaire before him, Lever believed it to be in the interest of the firm to house his workers in a high standard of building and comfort close to the factory.

By the early twentieth century he had created Port Sunlight Village, one of the earliest and certainly the most impressive housing estates, for his employees. Architecturally the estate is highly successful, being built from a variety of natural materials and vernacular styles by a number of distinguished architects, so preventing an overall architectural monotony. The comprehensive estate comprises, in addition to the factory and houses, a church, an art gallery, schools, a cottage hospital, library, bank, fire station, post office and shops, as well as an inn and working men's institute, both of which were later additions. In 1894 Lever \& Co. went public and soon was amalgamated with other soap firms. It was at its most successful high point by 1910.

William, the youngest of the three sons of Nehemiah Champion, stemmed from a West Country Quaker family long associated with the metal trades. His grandfather, also called Nehemiah, had been one of Abraham Darby's close Quaker friends when the brassworks at Baptist Mills was being established in 1702 and 1703. Nehemiah II took over the management of these works soon after Darby went to Coalbrookdale, and in 1719, as one of a group of Bristol copper smelters, he negotiated an agreement with Lord Falmouth to develop copper mines in the Redruth area in Cornwall. In 1723 he was granted a patent for a cementation brass-making process using finely granulated copper rather than the broken fragments of massive copper hitherto employed.

In 1730 he returned to Bristol after a tour of European metallurgical centres, and he began to develop an industrial process for the manufacture of pure zinc ingots in England. Metallic zinc or spelter was then imported at great expense from the Far East, largely for the manufacture of copper alloys of golden colour used for cheap jewellery. The process William developed, after six years of experimentation, reduced zinc oxide with charcoal at temperatures well above the boiling point of zinc. The zinc vapour obtained was condensed rapidly to prevent reoxidation and finally collected under water. This process, patented in 1738, was operated in secret until 1766 when Watson described it in his Chemical Essays. After encountering much opposition from the Bristol merchants and zinc importers, William decided to establish his own integrated brassworks at Warmley, five meals east of Bristol. The Warmley plant began to produce in 1748 and expanded rapidly. By 1767, when Warmley employed about 2,000 men, women and children, more capital was needed, requiring a Royal Charter of Incorporation. A consortium of Champion's competitors opposed this and secured its refusal. After this defeat William lost the confidence of his fellow directors, who dismissed him. He was declared bankrupt in 1769 and his works were sold to the British Brass Company, which never operated Warmley at full capacity, although it produced zinc on that site until 1784.

William Cockerill began his career in Lancashire by making "roving billies" and flying shuttles. He was reputed to have an extraordinary mechanical genius and it is said that he could make models of almost any machine. He followed in the footsteps of many other enterprising British engineers when in 1794 he went to St Petersburg in Russia, having been recommended as a skilful artisan to the Empress Catherine II. After her death two years later, her successor Paul sent Cockerill to prison because he failed to finish a model within a certain time. Cockerill, however, escaped to Sweden where he was commissioned to construct the locks on a public canal. He attempted to introduce textile machinery of his own invention but was unsuccessful and so in 1799 he removed to Verviers, Belgium, where he established himself as a manufacturer of textile machinery. In 1802 he was joined by James Holden, who before long set up his own machine-building business. In 1807 Cockerill moved to Liège where, with his three sons (William Jnr, Charles James and John), he set up factories for the construction of carding machines, spinning frames and looms for the woollen industry. He secured for Verviers supremacy in the woollen trade and introduced at Liège an industry of which England had so far possessed the monopoly. His products were noted for their fine craftsmanship, and in the heyday of the Napoleonic regime about half of his output was sold in France. In 1813 he imported a model of a Watt steam-engine from England and so added another range of products to his firm. Cockerill became a naturalized Belgian subject c. 1810, and a few years later he retired from the business in favour of his two younger sons, Charles James and John (b. 30 April 1790 Haslingden, Lancashire, England; d. 19 June 1840 Warsaw, Poland), but in 1830 at Andenne he converted a vast factory formerly used for calico printing into a paper mill. Little is known of his eldest son William, but the other two sons expanded the enterprise, setting up a woollen factory at Berlin after 1815 and establishing at Seraing-on-the-Meuse in 1817 blast furnaces, an iron foundry and a machine workshop which became the largest on the European continent. William Cockerill senior died in 1832 at the Château du Behrensberg, the residence of his son Charles James, near Aix-la-Chapelle.

Little is known for certain about William Marshall's early life, other than that he was baptized at Sinnington in the West Riding of Yorkshire. On his own account he was involved in trade in the West Indies from the age of 15 for a period of fourteen years. It is assumed that he was financially successful in this, for on his return to England in 1774 he was able to purchase Addisham Farm in Surrey. Having sacked his bailiff he determined to keep a minute book relating to all transactions on the farm, which he was now managing for himself. On these entries he made additional comments. The publication of these writings was the beginning of a substantial review of agriculture in Britain and a criticism of existing practices. From 1779 he acted as agent on a Norfolk estate, and his five years in that position resulted in The Rural Economy of Norfolk, the first of a series of county reviews that he was to write, intending the somewhat ambitious task of surveying the whole country. By 1808 Marshall had accumulated sufficient capital to be able to purchase a substantial property in the Vale of Cleveland, where he lived for the rest of his life. At the time of his death he was engaged in the erection of a building to serve as an agricultural college; the same building is now a rural-life museum.

The son of a smallholder farmer and self-taught surveyor, William Cobbett was brought up to farm work from an early age. In 1783 he took employment as an attorney's clerk in London, but not finding this to his liking he travelled to Chatham with the intention of joining the Navy. A mistake in "taking the King's shilling" found him in an infantry regiment. After a year's training he was sent out to Nova Scotia and quickly gained the rank of sergeant major. On leaving the Army he brought corruption charges against three officers in his regiment, but did not press with the prosecution. England was not to his taste, and he returned to North America with his wife.

In America Cobbett taught English to the growing French community displaced by the French Revolution. He found American criticism of Britain ill-balanced and in 1796 began to publish a daily newspaper under the title Porcupine's Gazetteer, in which he wrote editorials in defence of Britain. His writings won him little support from the Americans. However, on returning to London in 1800 he was offered, but turned down, the management of a Government newspaper. Instead he began to produce a daily paper called the Porcupine, which was superseded in 1802 by Cobbett's Political Register, this publication continued on a weekly basis until after his death. In 1803 he also began the Parliamentary Debates, which later merged into Hansard, the official report of parliamentary proceedings.

In 1805 Cobbett took a house and 300-acre (120-hectare) farm in Hampshire, from which he continued to write, but at the same time followed the pursuits he most enjoyed. In 1809 his criticism of the punishment given to mutineers in the militia at Ely resulted in his own imprisonment. On his release in 1812 he decided that the only way to remain an independent publisher was to move back to the USA. He bought a farm at Hampstead, Long Island, New York, and published A Year's Residence in America, which contains, amongst other things, an interesting account of a farmer's year.

Returning to Britain in the easier political climate of the 1820s, Cobbett bought a small seed farm in Kensington, then outside London. From there he made a number of journeys around the country, publishing accounts of them in his famous Rural Rides. His experiments and advice on the sowing and cultivation of crops, particularly turnips and swedes, and on forestry, were an important mechanism for the spread of ideas within the UK. He also claimed that he was the first to introduce the acacia and Indian maize to Britain. Much of his writing expresses a concern for the rural poor and he was firmly convinced that only parliamentary reform would achieve the changes needed. His political work and writing led to his election as Member of Parlaiment for Oldham in the 1835 election, which followed the Reform Act of 1832. However, by this time his energy was failing rapidly and he died peacefully at Normandy Farm, near Guildford, at the age of 73.

According to his own account, Caxton was born in Kent and received a schooling before entering the Mercers' Company, one of the most influential of the London guilds and engaged in the wholesale export trade in woollen goods and other wares, principally with the Low Countries. Around 1445, Caxton moved to Bruges, where he engaged in trade with such success that in 1462 he was appointed Governor of the English Nation in Bruges. He was entrusted with diplomatic missions, and his dealings with the court of Burgundy brought him into contact with the Duchess, Margaret of York, sister of the English King Edward IV. Caxton embarked on the production of fine manuscripts, making his own translations from the French for the Duchess and other noble patrons with a taste for this kind of literature. This trend became more marked after 1470–1 when Caxton lost his post in Bruges, probably due to the temporary overthrow of King Edward. Perhaps to satisfy an increasing demand for his texts, Caxton travelled to Cologne in 1471 to learn the art of printing. He set up a printing business in Bruges, in partnership with the copyist and bookseller Colard Mansion. There, late in 1474 or early the following year, Caxton produced the first book to be printed in English, and the first by an English printer, The Recuyell of the Histories of Troy, which he had translated from the French.

In 1476 Caxton returned to England and set up his printing and publishing business "at the sign of the Red Pale" within the precincts of Westminster Abbey. This was more conveniently placed than the City of London for the likely customers among the court and Members of Parliament for the courtly romances and devotional works he aimed to produce. Other printers followed but survived only a few years, whereas Caxton remained successful for fifteen years and then bequeathed a flourishing concern to his assistant Wynkyn de Worde. During that time, 107 printed works, including seventy-four books, issued from Caxton's press. Of these, some twenty were his own translations. As printer and publisher, he did much to promote English literature, above all by producing the first editions of the literary masterpieces of the Middle Ages, such as the works of Chaucer, Gower and Lydgate and Malory's Morte d'Arthur. Among the various dialects of spoken English in use at the time, Caxton adopted the language of London and the court and so did much to fix a permanent standard for written English.

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.

William was the second son and one of eleven children of Samuel Priestman, who had moved to Hull after retiring as a corn miller in Kirkstall, Leeds, and who in retirement had become a director of the North Eastern Railway Company. The family were strict Quakers, so William was sent to the Quaker School in Bootham, York. He left school at the age of 17 to start an engineering apprenticeship at the Humber Iron Works, but this company failed so the apprenticeship was continued with the North Eastern Railway, Gateshead. In 1869 he joined the hydraulics department of Sir William Armstrong \& Company, Newcastle upon Tyne, but after a year there his father financed him in business at a small, run down works, the Holderness Foundry, Hull. He was soon joined by his brother, Samuel, their main business being the manufacture of dredging equipment (grabs), cranes and winches. In the late 1870s William became interested in internal combustion engines. He took a sublicence to manufacture petrol engines to the patents of Eugène Etève of Paris from the British licensees, Moll and Dando. These engines operated in a similar manner to the non-compression gas engines of Lenoir. Failure to make the two-stroke version of this engine work satisfactorily forced him to pay royalties to Crossley Bros, the British licensees of the Otto four-stroke patents.

Fear of the dangers of petrol as a fuel, reflected by the associated very high insurance premiums, led William to experiment with the use of lamp oil as an engine fuel. His first of many patents was for a vaporizer. This was in 1885, well before Ackroyd Stuart. What distinguished the Priestman engine was the provision of an air pump which pressurized the fuel tank, outlets at the top and bottom of which led to a fuel atomizer injecting continuously into a vaporizing chamber heated by the exhaust gases. A spring-loaded inlet valve connected the chamber to the atmosphere, with the inlet valve proper between the chamber and the working cylinder being camoperated. A plug valve in the fuel line and a butterfly valve at the inlet to the chamber were operated, via a linkage, by the speed governor; this is believed to be the first use of this method of control. It was found that vaporization was only partly achieved, the higher fractions of the fuel condensing on the cylinder walls. A virtue was made of this as it provided vital lubrication. A starting system had to be provided, this comprising a lamp for preheating the vaporizing chamber and a hand pump for pressurizing the fuel tank.

Engines of 2–10 hp (1.5–7.5 kW) were exhibited to the press in 1886; of these, a vertical engine was installed in a tram car and one of the horizontals in a motor dray. In 1888, engines were shown publicly at the Royal Agricultural Show, while in 1890 two-cylinder vertical marine engines were introduced in sizes from 2 to 10 hp (1.5–7.5 kW), and later double-acting ones up to some 60 hp (45 kW). First, clutch and gearbox reversing was used, but reversing propellers were fitted later (Priestman patent of 1892). In the same year a factory was established in Philadelphia, USA, where engines in the range 5–20 hp (3.7–15 kW) were made. Construction was radically different from that of the previous ones, the bosses of the twin flywheels acting as crank discs with the main bearings on the outside.

On independent test in 1892, a Priestman engine achieved a full-load brake thermal efficiency of some 14 per cent, a very creditable figure for a compression ratio limited to under 3:1 by detonation problems. However, efficiency at low loads fell off seriously owing to the throttle governing, and the engines were heavy, complex and expensive compared with the competition.

Decline in sales of dredging equipment and bad debts forced the firm into insolvency in 1895 and receivers took over. A new company was formed, the brothers being excluded. However, they were able to attend board meetings, but to exert no influence. Engine activities ceased in about 1904 after over 1,000 engines had been made. It is probable that the Quaker ethics of the brothers were out of place in a business that was becoming increasingly cut-throat. William spent the rest of his long life serving others.

The only son of Sir William Herschel, the famous astronomer, John graduated from Cambridge in 1813 and went on to become a distinguished astronomer, mathematician and chemist. He left England in November 1833 to set up an observatory near Cape Town, South Africa, where he embarked on a study of the heavens in the southern hemisphere. He returned to England in the spring of 1838, and between 1850 and 1855 Herschel served as Master of the Royal Mint. He made several notable contributions to photography, perhaps the most important being his discovery in 1819 that hyposulphites (thiosulphates) would dissolve silver salts. He brought this property to the attention of W.H.F. Talbot, who in 1839 was using a common salt solution as a fixing agent for his early photographs. After trials, Talbot adopted "hypo", which was a far more effective fixative. It was soon adopted by other photographers and eventually became the standard photographic fixative, as it still is in the 1990s. After hearing of the first photographic process in January 1839, Herschel devised his own process within a week. In September 1839 he made the first photograph on glass. He is credited with introducing the words "positive", "negative" and "snapshot" to photography, and in 1842 he invented the cyanotype or "blueprint" process. This process was later to be widely adopted by engineers and architects for the reproduction of plans and technical drawings, a practice abandoned only in the late twentieth century.

William Buckle was the son of Thomas Buckle (1759–1849), a millwright who later assisted the 9th Earl of Dundonald (1749–1831) in his various inventions, principally machines for the manufacture of rope. Soon after the birth of William, the family moved from Alnwick to Hull, Yorkshire, where he received his education. The family again moved c.1808 to London, and William was apprenticed to Messrs Woolf \& Edwards, millwrights and engineers of Lambeth. During his apprenticeship he attended evening classes at a mechanical drawing school in Finsbury, which was then the only place of its kind in London.

After completing his apprenticeship, he was sent by Messrs Humphrys to Memel in Prussia to establish steamboats on the rivers and lakes there under the patronage of the Prince of Hardenburg. After about four years he returned to Britain and was employed by Boulton, Watt \& Co. to install the engines in the first steam mail packet for the service between Dublin and Holyhead. He was responsible for the engines of the steamship Lightning when it was used on the visit of George IV to Ireland.

About 1824 Buckle was engaged by Boulton, Watt \& Co. as Manager of the Soho Foundry, where he is credited with introducing the first large screw-cutting lathe. At Soho about 700 or 800 men were employed on a wide variety of engineering manufacture, including coining machinery for mints in many parts of the world, with some in 1826 for the Mint at the Soho Manufactory. In 1851, following the recommendations of a Royal Commission, the Royal Mint in London was reorganized and Buckle was asked to take the post of Assistant Coiner, the senior executive officer under the Deputy Master. This he accepted, retaining the post until the end of his life.

At Soho, Buckle helped to establish a literary and scientific institution to provide evening classes for the apprentices and took part in the teaching. He was an original member of the Institution of Mechanical Engineers, which was founded in Birmingham in January 1847, and a member of their Council from then until 1855. He contributed a number of papers in the early years, including a memoir of William Murdock whom he had known at Soho; he resigned from the Institution in 1856 after his move to London. He was an honorary member of the London Association of Foreman Engineers.

The family fortunes having been extinguished by the South Sea Bubble of 1720, Cookworthy and his brother had to fend for themselves. They set up, and succeeded, in the pharmacy trade. At the age of 31, however, William left the business, and after a period of probation he became a minister in the Society of Friends. In a letter of 5 May 1745, Cookworthy mentions some samples of kaolin and china or growan stone that had been brought to him from Virginia. He found similar materials at Treginning Hill in Cornwall, and between 1755 and 1758 he found sufficiently pure china clay and china stone to make a pure white porcelain. Cookworthy took out a patent for his discovery in 1768 which covered the manufacture of porcelain from moonstone or growan and growan clay, with a glaze made from china stone to which lime and fern ash or magnesia alba (basic carbonate of magnesium) were added. Cookworthy's experiments had been carried out on the property of Lord Camelford, who later assisted him, in the company of other Quakers, in setting up a works at Coxside, Plymouth, to manufacture the ware; the works employed between fifty and sixty people. In the absence of coal, Cookworthy resorted to wood as fuel, but this was scarce, so in 1770 he transferred his operation to Castle Green, Bristol. However, he had no greater success there, and in 1773 he sold the entire interest in porcelain manufacture to Richard Champion (1743–91), although Cookworthy and his heirs were to receive royalties for ninety-nine years. Champion, who had been working with Cookworthy since 1764 and was active in Bristol city affairs, continued the firm as Richard Champion \& Co., but when in 1775 Champion tried to renew Cookworthy's patent, Wedgwood and other Staffordshire potters challenged him. After litigation, the use of kaolin and china stone was thrown open to general use. The Staffordshire potters made good use of this new-found freedom and Champion was forced to sell the patent to them and dispose of his factory the following year. The potters of Staffordshire said of Cookworthy, "the greatest service ever conferred by one person on the pottery manufacturers is that of making them acquainted with china clay".

Ill health forced Adams to live abroad when he was a young man and when he returned to England in the early 1830s he became a partner in his father's firm of coachbuilders. Coaches during that period were steered by a centrally pivoted front axle, which meant that the front wheels had to swing beneath the body and were therefore made smaller than the rear wheels. Adams considered this design defective and invented equirotal coaches, built by his firm, in which the front and rear wheels were of equal diameter and the coach body was articulated midway along its length so that the front part pivoted. He also applied himself to improving vehicles for railways, which were developing rapidly then.

In 1843 he opened his own engineering works, Fairfield Works in north London (he was not related to his contemporary William Adams, who was appointed Locomotive Superintendent to the North London Railway in 1854). In 1847 he and James Samuel, Engineer to the Eastern Counties Railway, built for that line a small steam inspection car, the Express, which was light enough to be lifted off the track. The following year Adams built a broad-gauge steam railcar, the Fairfield, for the Bristol \& Exeter Railway at the insistance of the line's Engineer, C.H.Gregory: self-propelled and passenger-carrying, this was the first railcar. Adams developed the concept further into a light locomotive that could haul two or three separate carriages, and light locomotives built both by his own firm and by other noted builders came into vogue for a decade or more.

In 1847 Adams also built eight-wheeled coaches for the Eastern Counties Railway that were larger and more spacious than most others of the day: each in effect comprised two four-wheeled coaches articulated together, with wheels that were allowed limited side-play. He also realized the necessity for improvements to railway track, the weakest point of which was the joints between the rails, whose adjoining ends were normally held in common chairs. Adams invented the fishplated joint, first used by the Eastern Counties Railway in 1849 and subsequently used almost universally.

Adams was a prolific inventor. Most important of his later inventions was the radial axle, which was first applied to the leading and trailing wheels of a 2–4–2 tank engine, the White Raven, built in 1863; Adams's radial axle was the forerunner of all later radial axles. However, the sprung tyres with which White Raven was also fitted (an elastic steel hoop was interposed between wheel centre and tyre) were not perpetuated. His inventiveness was not restricted to engineering: in matters of dress, his adoption, perhaps invention, of the turn-down collar at a time when men conventionally wore standup collars had lasting effect.

After graduating from University College, London, Ayrton became for a short time a pupil of Sir William Thomson in Glasgow. For five years he was employed in the Indian Telegraph Service, eventually as Superintendent, where he assisted in revolutionizing the system, devising methods of fault detection and elimination. In 1873 he was invited by the Japanese Government to assist as Professor of Physics and Telegraphy in founding the Imperial College of Engineering in Tokyo. There he created a teaching laboratory that served as a model for those he was later to organize in England and which were copied elsewhere. It was in Tokyo that his joint researches with Professor John Perry began, an association that continued after their return to England. In 1879 he became Professor of Technical Physics at the City and Guilds Institute in Finsbury, London, and later was appointed Professor of Physics at the Central Institution in South Kensington.

The inventions of Avrton and Perrv included an electric tricycle in 1882, the first practicable portable ammeter and other electrical measuring instruments. By 1890, when the research partnership ended, they had published nearly seventy papers in their joint names, the emphasis being on a mathematical treatment of subjects including electric motor design, construction of electrical measuring instruments, thermodynamics and the economical use of electric conductors. Ayrton was then employed as a consulting engineer by government departments and acted as an expert witness in many important patent cases.

William Taylor served an apprenticeship from 1880 to 1885 in London with Paterson and Cooper, electrical engineers and instrument makers. He studied at the Finsbury Technical College under Professors W.E.Ayrton (1847–1908) and John Perry (1850–1920). He remained with Paterson and Cooper until 1887, when he joined his elder brother, who had set up in Leicester as a manufacturer of optical instruments. The firm was then styled T.S. \& W.Taylor and a few months later, when H.W.Hobson joined them as a partner, it became Taylor, Taylor and Hobson, as it was known for many years.

William Taylor was mainly responsible for technical developments in the firm and he designed the special machine tools required for making lenses and their mountings. However, his most notable work was in originating methods of measuring and gauging screw threads. He proposed a standard screw-thread for lens mountings that was adopted by the Royal Photographic Society, and he served on screw thread committees of the British Standards Institution and the British Association. His interest in golf led him to study the flight of the golf ball, and he designed and patented the "Dimple" golf ball and a mechanical driving machine for testing golf balls.

He was an active member of the Institution of Mechanical Engineers, being elected Associate Member in 1894, Member in 1901 and Honorary Life Member in 1936. He served on the Council from 1918 and was President in 1932. He took a keen interest in engineering education and advocated the scientific study of materials, processes and machine tools, and of management. His death occurred suddenly while he was helping to rescue his son's car from a snowdrift.

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.

Born into comfortable circumstances, Burrell chose ship construction as his career. Ability aided by financial influence helped professional advancement, and by his early thirties he possessed a shipyard at Ratcliffe on the River Thames. Ship design was then unscientific, shrouded in mystique, and it required patience and perseverance to penetrate the conventions of the craft.

From the 1600s Burrell had been investing in the East India Company. In 1607 the Company decided to build ships in their own right, and Burrell was appointed as the first Master Shipwright, a post he held for nearly twenty years. The first ship, Trade's Increase, of 1,000-tons burthen, was the largest ship built in England until the eighteenth century, but following a mishap at launch and the ship's subsequent loss on its maiden voyage, the Company reassessed its policy and built smaller ships. Burrell's foresight can be gauged by his involvement in two private commercial undertakings in Ireland; one to create oak forests for shipbuilding, and the other to set up a small ironworks. In 1618 a Royal Commission was appointed to enquire into the poor condition of the Navy, and with the help of Burrell it was ruled that the main problems were neglect and corruption. With his name being known and his good record of production, the Royal Navy ordered no fewer than ten warships from Burrell in the four-year period from 1619 to 1623. With experience in the military and commercial sectors, Burrell can be regarded as an all-round and expert shipbuilder of the Stuart period. He used intuition at a time when there were no scientific rules and little reliable empiric guidance on ship design.

Froude was educated at a preparatory school at Buckfastleigh, and then at Westminster School, London, before entering Oriel College, Oxford, to read mathematics and classics. Between 1836 and 1838 he served as a pupil civil engineer, and then he joined the staff of Isambard Kingdom Brunel on various railway engineering projects in southern England, including the South Devon Atmospheric Railway. He retired from professional work in 1846 and lived with his invalid father at Dartington Parsonage. The next twenty years, while apparently unproductive, were important to Froude as he concentrated his mind on difficult mathematical and scientific problems. Froude married in 1839 and had five children, one of whom, Robert Edmund Froude (1846–1924), was to succeed him in later years in his research work for the Admiralty. Following the death of his father, Froude moved to Paignton, and there commenced his studies on the resistance of solid bodies moving through fluids. Initially these were with hulls towed through a house roof storage tank by wires taken over a pulley and attached to falling weights, but the work became more sophisticated and was conducted on ponds and the open water of a creek near Dartmouth. Froude published work on the rolling of ships in the second volume of the Transactions of the then new Institution of Naval Architects and through this became acquainted with Sir Edward Reed. This led in 1870 to the Admiralty's offer of £2,000 towards the cost of an experimental tank for ship models at Torquay. The tank was completed in 1872 and tests were carried out on the model of HMS Greyhound following full-scale towing trials which had commenced on the actual ship the previous year. From this Froude enunciated his Law of Comparisons, which defines the rules concerning the relationship of the power required to move geometrically similar floating bodies across fluids. It enabled naval architects to predict, from a study of a much less expensive and smaller model, the resistance to motion and the power required to move a full-size ship. The work in the tank led Froude to design a model-cutting machine, dynamometers and machinery for the accurate ruling of graph paper. Froude's work, and later that of his son, was prodigious and covered many fields of ship design, including powering, propulsion, rolling, steering and stability. In only six years he had stamped his academic authority on the new science of hydrodynamics, served on many national committees and corresponded with fellow researchers throughout the world. His health suffered and he sailed for South Africa to recuperate, but he contracted dysentery and died at Simonstown. He will be remembered for all time as one of the greatest "fathers" of naval architecture.
