Edmund Cartwright, the fourth son of William Cartwright, was educated at Wakefield Grammar School, and went to University College, Oxford, at the age of 14. By special act of convocation in 1764, he was elected Fellow of Magdalen College. He married Alice Whitaker in 1772 and soon after was given the ecclesiastical living of Brampton in Derbyshire. In 1779 he was presented with the living of Goadby, Marwood, Leicestershire, where he wrote poems, reviewed new works, and began agricultural experiments. A visit to Matlock in the summer of 1784 introduced him to the inventions of Richard Arkwright and he asked why weaving could not be mechanized in a similar manner to spinning. This began a remarkable career of inventions.

Cartwright returned home and built a loom which required two strong men to operate it. This was the first attempt in England to develop a power loom. It had a vertical warp, the reed fell with the weight of at least half a hundredweight and, to quote Gartwright's own words, "the springs which threw the shuttle were strong enough to throw a Congreive [sic] rocket" (Strickland 19.71:8—for background to the "rocket" comparison, see Congreve, Sir William). Nevertheless, it had the same three basics of weaving that still remain today in modern power looms: shedding or dividing the warp; picking or projecting the shuttle with the weft; and beating that pick of weft into place with a reed. This loom he proudly patented in 1785, and then he went to look at hand looms and was surprised to see how simply they operated. Further improvements to his own loom, covered by two more patents in 1786 and 1787, produced a machine with the more conventional horizontal layout that showed promise; however, the Manchester merchants whom he visited were not interested. He patented more improvements in 1788 as a result of the experience gained in 1786 through establishing a factory at Doncaster with power looms worked by a bull that were the ancestors of modern ones. Twenty-four looms driven by steam-power were installed in Manchester in 1791, but the mill was burned down and no one repeated the experiment. The Doncaster mill was sold in 1793, Cartwright having lost £30,000, However, in 1809 Parliament voted him £10,000 because his looms were then coming into general use.

In 1789 he began working on a wool-combing machine which he patented in 1790, with further improvements in 1792. This seems to have been the earliest instance of mechanized combing. It used a circular revolving comb from which the long fibres or "top" were. carried off into a can, and a smaller cylinder-comb for teasing out short fibres or "noils", which were taken off by hand. Its output equalled that of twenty hand combers, but it was only relatively successful. It was employed in various Leicestershire and Yorkshire mills, but infringements were frequent and costly to resist. The patent was prolonged for fourteen years after 1801, but even then Cartwright did not make any profit. His 1792 patent also included a machine to make ropes with the outstanding and basic invention of the "cordelier" which he communicated to his friends, including Robert Fulton, but again it brought little financial benefit. As a result of these problems and the lack of remuneration for his inventions, Cartwright moved to London in 1796 and for a time lived in a house built with geometrical bricks of his own design.

Other inventions followed fast, including a tread-wheel for cranes, metallic packing for pistons in steam-engines, and bread-making and brick-making machines, to mention but a few. He had already returned to agricultural improvements and he put forward suggestions in 1793 for a reaping machine. In 1801 he received a prize from the Board of Agriculture for an essay on husbandry, which was followed in 1803 by a silver medal for the invention of a three-furrow plough and in 1805 by a gold medal for his essay on manures. From 1801 to 1807 he ran an experimental farm on the Duke of Bedford's estates at Woburn.

From 1786 until his death he was a prebendary of Lincoln. In about 1810 he bought a small farm at Hollanden near Sevenoaks, Kent, where he continued his inventions, both agricultural and general. Inventing to the last, he died at Hastings and was buried in Battle church.

Arkwright was the youngest of thirteen children and was apprenticed to a barber; when he was about 18, he followed this trade in Bol ton. In 1755 he married Patients Holt, who bore him a son before she died, and he remarried in 1761, to Margaret Biggins. He prospered until he took a public house as well as his barber shop and began to lose money. After this failure, he travelled around buying women's hair for wigs.

In the late 1760s he began spinning experiments at Preston. It is not clear how much Arkwright copied earlier inventions or was helped by Thomas Highs and John Kay but in 1768 he left Preston for Nottingham, where, with John Smalley and David Thornley as partners, he took out his first patent. They set up a mill worked by a horse where machine-spun yarn was produced successfully. The essential part of this process lay in drawing out the cotton by rollers before it was twisted by a flyer and wound onto the bobbin. The partners' resources were not sufficient for developing their patent so Arkwright found new partners in Samuel Need and Jedediah Strutt, hosiers of Nottingham and Derby. Much experiment was necessary before they produced satisfactory yarn, and in 1771 a water-driven mill was built at Cromford, where the spinning process was perfected (hence the name "waterframe" was given to his spinning machine); some of this first yarn was used in the hosiery trade. Sales of all-cotton cloth were initially limited because of the high tax on calicoes, but the tax was lowered in 1774 by Act of Parliament, marking the beginning of the phenomenal growth of the cotton industry. In the evidence for this Act, Arkwright claimed that he had spent £12,000 on his machine. Once Arkwright had solved the problem of mechanical spinning, a bottleneck in the preliminary stages would have formed but for another patent taken out in 1775. This covered all preparatory processing, including some ideas not invented by Arkwright, with the result that it was disputed in 1783 and finally annulled in 1785. It contained the "crank and comb" for removing the cotton web off carding engines which was developed at Cromford and solved the difficulty in carding. By this patent, Arkwright had mechanized all the preparatory and spinning processes, and he began to establish water-powered cotton mills even as far away as Scotland. His success encouraged many others to copy him, so he had great difficulty in enforcing his patent Need died in 1781 and the partnership with Strutt ended soon after. Arkwright became very rich and financed other spinning ventures beyond his immediate control, such as that with Samuel Oldknow. It was estimated that 30,000 people were employed in 1785 in establishments using Arkwright's patents. In 1786 he received a knighthood for delivering an address of thanks when an attempt to assassinate George III failed, and the following year he became High Sheriff of Derbyshire. He purchased the manor of Cromford, where he died in 1792.

Richard Roberts was the son of a shoemaker and tollkeeper and received only an elementary education at the village school. At the age of 10 his interest in mechanics was stimulated when he was allowed by the Curate, the Revd Griffith Howell, to use his lathe and other tools. As a young man Roberts acquired a considerable local reputation for his mechanical skills, but these were exercised only in his spare time. For many years he worked in the local limestone quarries, until at the age of 20 he obtained employment as a pattern-maker in Staffordshire. In the next few years he worked as a mechanic in Liverpool, Manchester and Salford before moving in 1814 to London, where he obtained employment with Henry Maudslay. In 1816 he set up on his own account in Manchester. He soon established a reputation there for gear-cutting and other general engineering work, especially for the textile industry, and by 1821 he was employing about twelve men. He built machine tools mainly for his own use, including, in 1817, one of the first planing machines.

One of his first inventions was a gas meter, but his first patent was obtained in 1822 for improvements in looms. His most important contribution to textile technology was his invention of the self-acting spinning mule, patented in 1825. The normal fourteen-year term of this patent was extended in 1839 by a further seven years. Between 1826 and 1828 Roberts paid several visits to Alsace, France, arranging cottonspinning machinery for a new factory at Mulhouse. By 1826 he had become a partner in the firm of Sharp Brothers, the company then becoming Sharp, Roberts \& Co. The firm continued to build textile machinery, and in the 1830s it built locomotive engines for the newly created railways and made one experimental steam-carriage for use on roads. The partnership was dissolved in 1843, the Sharps establishing a new works to continue locomotive building while Roberts retained the existing factory, known as the Globe Works, where he soon after took as partners R.G.Dobinson and Benjamin Fothergill (1802–79). This partnership was dissolved c. 1851, and Roberts continued in business on his own for a few years before moving to London as a consulting engineer.

During the 1840s and 1850s Roberts produced many new inventions in a variety of fields, including machine tools, clocks and watches, textile machinery, pumps and ships. One of these was a machine controlled by a punched-card system similar to the Jacquard loom for punching rivet holes in plates. This was used in the construction of the Conway and Menai Straits tubular bridges. Roberts was granted twenty-six patents, many of which, before the Patent Law Amendment Act of 1852, covered more than one invention; there were still other inventions he did not patent. He made his contribution to the discussion which led up to the 1852 Act by publishing, in 1830 and 1833, pamphlets suggesting reform of the Patent Law.

In the early 1820s Roberts helped to establish the Manchester Mechanics' Institute, and in 1823 he was elected a member of the Literary and Philosophical Society of Manchester. He frequently contributed to their proceedings and in 1861 he was made an Honorary Member. He was elected a Member of the Institution of Civil Engineers in 1838. From 1838 to 1843 he served as a councillor of the then-new Municipal Borough of Manchester. In his final years, without the assistance of business partners, Roberts suffered financial difficulties, and at the time of his death a fund for his aid was being raised.

Clymer was born on his father's farm, of a family that emigrated from Switzerland in the early eighteenth century. He attended local schools, helping out on the farm in his spare time, and he showed a particular talent for maintaining farm machinery. At the age of 16 he learned the trade of carpenter and joiner, which he followed in the same district for over twenty-five years. During that time, he showed his talent for mechanical invention in many ways, including the invention of a plough specially adapted to the local soils. Around 1800, he moved to Philadelphia, where his interest was aroused by the erection of the first bridge over the Schuylkill River. He devised a pump to remove water from the cofferdams at a rate of 500 gallons per day, superior to any other pumps then in use. He obtained a US patent for this in 1801, and a British one soon after.

Clymer then turned his attention to the improvement of the printing press. For three and a half centuries after its invention, the old wooden-framed press had remained virtually unchanged except in detail. The first real change came in 1800 with the introduction of the iron press by Earl Stanhope. Modified versions were developed by other inventors, notably George Clymer, who after more than ten years' effort achieved his Columbian press. With its new system of levers, it enabled perfect impressions to be obtained with far less effort by the pressman. The Columbian was also notable for its distinctive cast-iron ornamentation, including a Hermes on each pillar and alligators and other reptiles on the levers. Most spectacular, it was surmounted by an American spread eagle, usually covered in gilt, which also served as a counterweight to raise the platen. The earliest known Columbian, surviving only in an illustration, bears the inscription Columbian Press/No.25/invented by George Clymer/Anno Domini 1813/Made in Philadelphia 1816. Few American printers could afford the US$400 selling price, so in 1817 Clymer went to England, where it was taken up enthusiastically. He obtained a British patent for it the same year, and by the following March it was being manufactured by the engineering firm R.W.Cope, although Clymer was probably making it on his own account soon afterwards. The Columbian was widely used for many years and continued to be made even into the twentieth century. The King of the Netherlands awarded Clymer a gold medal for his invention and the Tsar of Russia gave him a present for installing the press in Russia. Doubtless for business reasons, Clymer spent most of his remaining years in England and Europe.

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.

Little is known of the early years of Savery's life and no trace has been found that he served in the Army, so the title "Captain" is thought to refer to some mining appointment, probably in the West of England. He may have been involved in the Glorious Revolution of 1688, for later he was well known to William of Orange. From 1705 to 1714 he was Treasurer for Sick and Wounded Seamen, and in 1714 he was appointed Surveyor of the Water Works at Hampton Court, a post he held until his death the following year. He was interested in mechanical devices; amongst his early contrivances was a clock.

He was the most prolific inventor of his day, applying for seven patents, including one in 1649, for polishing plate glass which may have been used. His idea for 1697 for propelling ships with paddle-wheels driven by a capstan was a failure, although regarded highly by the King, and was published in his first book, Navigation Improved (1698). He tried to patent a new type of floating mill in 1707, and an idea in 1710 for baking sea coal or other fuel in an oven to make it clean and pure.

His most famous invention, however, was the one patented in 1698 "for raising water by the impellent force of fire" that Savery said would drain mines or low-lying land, raise water to supply towns or houses, and provide a source of water for turning mills through a water-wheel. Basically it consisted of a receiver which was first filled with steam and then cooled to create a vacuum by having water poured over the outside. The water to be pumped was drawn into the receiver from a lower sump, and then high-pressure steam was readmitted to force the water up a pipe to a higher level. It was demonstrated to the King and the Royal Society and achieved some success, for a few were installed in the London area and a manufactory set up at Salisbury Court in London. He published a book, The Miner's Friend, about his engine in 1702, but although he made considerable improvements, due to excessive fuel consumption and materials which could not withstand the steam pressures involved, no engines were installed in mines as Savery had hoped. His patent was extended in 1699 until 1733 so that it covered the atmospheric engine of Thomas Newcomen who was forced to join Savery and his other partners to construct this much more practical engine.

Daniel Bourn may well have been a native of Lancashire. He set up a fourth Paul-Wyatt cotton-spinning mill at Leominster, Herefordshire, possibly in 1744, although the earliest mention of it is in 1748. His only known partner in this mill was Henry Morris, a yarn dealer who in 1743 had bought a grant of spindles from Paul at the low rate of 30 shillings or 40 shillings per spindle when the current price was £3 or £4. When Bourn patented his carding engine in 1748, he asked Wyatt for a grant of spindles, to which Wyatt agreed because £100 was offered immedi-ately. The mill, which was probably the only one outside the control of Paul and his backers, was destroyed by fire in 1754 and was not rebuilt, although Bourn and his partners had considerable hopes for it. Bourn was said to have lost over £1,600 in the venture.

Daniel Bourn described himself as a wool and cotton dealer of Leominster in his patent of 1748 for his carding engine. The significance of this invention is the use of rotating cylinders covered with wire clothing. The patent drawing shows four cylinders, one following the other to tease out the wool, but Bourn was unable to discover a satisfactory method of removing the fibres from the last cylinder. It is possible that Robert Peel in Lancashire obtained one of these engines through Morris, and that James Hargreaves tried to improve it; if so, then some of the early carding engines in the cotton industry were derived from Bourn's.

While at the technical institute in Graz, Austria, Tesla's attention was drawn to the desirability of constructing a motor without a commutator. He considered the sparking between the commutator and brushes of the Gramme machine when run as a motor a serious defect. In 1881 he went to Budapest to work on the telegraph system and while there conceived the principle of the rotating magnetic field, upon which all polyphase induction motors are based. In 1882 Tesla moved to Paris and joined the Continental Edison Company. After building a prototype of his motor he emigrated to the United States in 1884, becoming an American citizen in 1889. He left Edison and founded an independent concern, the Tesla Electric Company, to develop his inventions.

The importance of Tesla's first patents, granted in 1888 for alternating-current machines, cannot be over-emphasized. They covered a complete polyphase system including an alternator and induction motor. Other patents included the polyphase transformer, synchronous motor and the star connection of three-phase machines. These were to become the basis of the whole of the modern electric power industry. The Westinghouse company purchased the patents and marketed Tesla motors, obtaining in 1893 the contract for the Niagara Falls two-phase alternators driven by 5,000 hp (3,700 kW) water turbines.

After a short period with Westinghouse, Tesla resigned to continue his research into high-frequency and high-voltage phenomena using the Tesla coil, an air-cored transformer. He lectured in America and Europe on his high-frequency devices, enjoying a considerable international reputation. The name "tesla" has been given to the SI unit of magnetic-flux density. The induction motor became one of the greatest advances in the industrial application of electricity. A claim for priority of invention of the induction motor was made by protagonists of Galileo Ferraris (1847–1897), whose discovery of rotating magnetic fields produced by alternating currents was made independently of Tesla's. Ferraris demonstrated the phenomenon but neglected its exploitation to produce a practical motor. Tesla himself failed to reap more than a small return on his work and later became more interested in scientific achievement than commercial success, with his patents being infringed on a wide scale.
