Allen was taken to the United States from England when he was 12 years old. He became an engineer on the Curlew, a freight boat running between New York and Providence. A defect which caused the engine to race in rough weather led Allen to invent a new valve gear, but he found it could not be fitted to the Corliss engine. In 1856 he patented an improved form of valve and operating gear to reduce back-pressure in the cylinder, which was in fact the reverse of what happened in his later engines. In 1860 he repaired the engines of a New York felt-hat manufacturer, Henry Burr, and that winter he was introduced to Charles Porter. Porter realized the potential of Allen's valves for his idea of a high-speed engine, and the Porter-Allen engine became the pioneer of high-speed designs.

Porter persuaded Allen to patent his new valves and two patents were obtained in 1862. These valves could be driven positively and yet the travel of the inlet could be varied to give the maximum expansion at different cut-offs. Also, the valves allowed an exceptionally good flow of steam. While Porter went to England and tried to interest manufacturers there, Allen remained in America and continued work on the engine. Within a few years he invented an inclined watertube boiler, but he seemed incapable of furthering his inventions once they had been placed on the market. Although he mortgaged his own house in order to help finance the factory for building the steam engine, in the early 1870s he left Porter and built a workshop of his own at Mott Haven. There he invented important systems for riveting by pneumatic machines through both percussion and pressure which led into the production of air compressors and riveting machines.

The son of a textile manufacturer, as a youth Colt displayed an interest in chemistry, largely through bleaching and dyeing processes used in his father's business, and lectured to lay audiences on it. In 1832 he took ship as a deckhand on a voyage to India; the concept of the revolver is supposed to have come to him from watching the ship's wheel.

Upon his return to the USA he described the idea to the US Patent Office, but did not register it until four years later, having taken out patents in Britain and France during a visit to Europe in 1835. He formed a company to manufacture his invention, but it failed in 1842. Even so, note had been taken of his weapon, and in 1846, upon the outbreak of the war with Mexico, the US Government placed an order for his revolver that was executed by the Eli Whitney arms factory in his native Hartford. Thereafter Colt set up another company, this time successfully. He also took an interest in other fields, experimenting with a submarine battery and electrically detonated mines, and opened a submarine telegraph between New York and Coney Island in 1843.

Alanson Harris was the first often children born to the wife of a circuit rider and preacher. His father's wanderings left Alanson at an early age in charge of the running of the family farm on the Grand River in Canada; also, his father's preference was for tinkering with machines rather than for farming. However, when he was 13 Alanson had to go out to work in order to bring badly needed cash to augment the family income. He worked at a sawmill in the small village of Boston, becoming Boss Sawyer and then Foreman after ten years. In 1839 the family moved to Mount Pleasant, and the following year Alanson married Mary Morgan, the daughter of a well-to-do pioneer Welsh farmer. He entered into a brief partnership with his father to build a sawmill at Whiteman's Creek, but within a few months his father returned to preaching and Alanson became the sole proprietor. After a successful early period Alanson recognized the signs of decline in the timber market, and in 1857 he sold the mill, moved to Beamsville, Niagara, and bought a small factory from which he produced the flop-over hay rake invented by his father. In 1863 he took his eldest son into partnership; the latter returned from a visit to the United States with the sole rights to produce the Kirby mower and reaper. The Crimean War created a market for corn, which gave a great boost to North American farming and, in its turn, to machinery production. This was reinforced by the tariff agreements between the United States and Canada. By the 1880s Harris and Massey between them accounted for two thirds of the harvesting machines sold in Canada, and they also supplied machines abroad. By the end of the decade the mutual benefits of joining forces were apparent and by 1891 an agreement was reached, with Alanson Harris and A.H.Massey on the first board.

Frederick W.Howe attended local schools until the age of 16 and then entered the machine shop of Gay \& Silver at North Chelmsford, Massachusetts, as an apprentice and remained with that firm for nine years. He then joined Robbins, Kendall \& Lawrence of Windsor, Vermont, as Assistant to Richard S. Lawrence in designing machine tools. A year later (1848) he was made Plant Superintendent. During his time with this firm, Howe designed a profiling machine which was used in all gun shops in the United States: a barrel-drilling and rifling machine, and the first commercially successful milling machine. Robbins \& Lawrence took to the Great Exhibition of 1851 in London, England, a set of rifles built on the interchangeable system. The interest this created resulted in a visit of some members of the British Royal Small Arms Commission to America and subsequently in an order for 150 machine tools, jigs and fixtures from Robbins \& Lawrence, to be installed at the small-arms factory at Enfield. From 1853 to 1856 Howe was in charge of the design and building of these machines. In 1856 he established his own armoury at Newark, New Jersey, but transferred after two years to Middletown, Connecticut, where he continued the manufacture of small arms until the outbreak of the Civil War. He then became Superintendent of the armoury of the Providence Tool Company at Providence, Rhode Island, and served in that capacity until the end of the war. In 1865 he went to Bridgeport, Connecticut, to assist Elias Howe with the manufacture of his sewing machine. After the death of Elias Howe, Frederick Howe returned to Providence to join the Brown \& Sharpe Manufacturing Company. As Superintendent of that establishment he worked with Joseph R. Brown in the development of many of the firm's products, including machinery for the Wilcox \& Gibbs sewing machine then being made by Brown \& Sharpe. From 1876 Howe was in business on his own account as a consulting mechanical engineer and in his later years he was engaged in the development of shoe machinery and in designing a one-finger typewriter, which, however, was never completed. He was granted several patents, mainly in the fields of machine tools and firearms. As a designer, Howe was said to have been a perfectionist, making frequent improvements; when completed, his designs were always sound.

Henry Maudslay was the third son of an ex-soldier and storekeeper at Woolwich Arsenal. At the age of 12 he was employed at the Arsenal filling cartridges; two years later he was transferred to the woodworking department, adjacent to the smithy, to which he moved when 15 years old. He was a rapid learner, and three years later Joseph Bramah took him on for the construction of special tools required for the mass-production of his locks. Maudslay was thus employed for the next eight years. He became Bramah's foreman, married his housekeeper, Sarah Tindale, and, unable to better himself, decided to leave and set up on his own. He soon outgrew his first premises in Wells Street and moved to Margaret Street, off Oxford Street, where some examples of his workmanship were displayed in the window. These caught the attention of a visiting Frenchman, de Bacquancourt; he was a friend of Marc Isambard Brunel, who was then in the early stages of designing the block-making machinery later installed at Portsmouth dockyard.

Brunel wanted first a set of working models, as he did not think that the Lords of the Admiralty would be capable of understanding engineering drawings; Maudslay made these for him within the next two years. Sir Samuel Bentham, Inspector-General of Naval Works, agreed that Brunel's system was superior to the one that he had gone some way in developing; the Admiralty approved, and an order was placed for the complete plant. The manufacture of the machinery occupied Maudslay for the next six years; he was assisted by a draughtsman whom he took on from Portsmouth dockyard, Joshua Field (1786–1863), who became his partner in Maudslay, Son and Field. There were as many as eighty employees at Margaret Street until, in 1810, larger premises became necessary and a new works was built at Lambeth Marsh where, eventually, there were up to two hundred workers. The new factory was flanked by two houses, one of which was occupied by Maudslay, the other by Field. The firm became noted for its production of marine steam-engines, notably Maudslay's table engine which was first introduced in 1807.

Maudslay was a consummate craftsman who was never happier than when working at his bench or at a machine tool; he was also one of the first engineers to appreciate the virtues of standardization. Evidence of this appreciation is to be found in his work in the development of the Bramah lock and then on the machine tools for the manufacture of ship's blocks to Marc Brunel's designs; possibly his most important contribution was the invention in 1797 of the metal lathe. He made a number of surface plates of the finest quality. The most celebrated of his numerous measuring devices was a micrometer-based machine which he termed his "Lord Chancellor" because, in the machine shop, it represented the "final court of appeal", measuring to one-thousandth of an inch.

Cyrus McCormick's father, a farmer, began to experiment unsuccessfully with a harvesting machine between 1809 and 1816. His son took up the challenge and gave his first public demonstration of his machine in 1831. It cut a 4 ft swathe, but, wanting to perfect the machine, he waited until 1834 before patenting it, by which time he felt that his invention was threatened by others of similar design. In the same year he entered an article in the Mechanics Magazine, warning competitors off his design. His main rival was Obed Hussey who contested McCormick's claim to the originality of the idea, having patented his own machine six months before McCormick.

A competition between the two machines was held in 1843, the judges favouring McCormick's, even after additional trials were conducted after objections of unfairness from Hussey. The rivalry continued over a number of years, being avidly reported in the agricultural press. The publicity did no harm to reaper sales, and McCormick sold twenty-nine machines in 1843 and fifty the following year.

As the westward settlement movement progressed, so the demand for McCormick's machine grew. In order to be more central to his markets, McCormick established himself in Chicago. In partnership with C.M.Gray he established a factory to produce 500 harvesters for the 1848 season. By means of advertising and offers of credit terms, as well as production-line assembly, McCormick was able to establish himself as sole owner and also control all production, under the one roof. By the end of the decade he dominated reaper production but other developments were to threaten this position; however, foreign markets were appearing at the same time, not least the opportunities of European sales stimulated by the Great Exhibition in 1851. In the trials arranged by the Royal Agricultural Society of England the McCormick machine significantly outperformed that of Hussey's, and as a result McCormick arranged for 500 to be made under licence in England.

In 1874 McCormick bought a half interest in the patent for a wire binder from Charles Withington, a watchmaker from Janesville, Wisconsin, and by 1885 a total of 50,000 wire binders had been built in Chicago. By 1881 McCormick was producing twine binders using Appleby's twine knotter under a licence agreement, and by 1885 the company was producing only twine binders. The McCormick Company was one of the co-founders of the International Harvester Company in 1901.

After studying at the West of Scotland Technical College in Glasgow, in January 1895 Morrison was appointed Engineer to the newly formed British Aluminium Company Limited (BAC); it was with this organization that he spent his entire career. The company secured the patent rights to the Héroult and Bayer processes. It constructed a 200 tonne per year electrolytic plant at Foyers on the shore of Loch Ness, together with an adjacent 5000 kW hydroelectric scheme, and it built an alumina factory at Larne Harbour in north-eastern Ireland. Morrison was soon Manager at Foyers, and he became the company's Joint Technical Adviser. In 1910 he was made General Manager, and later he was appointed Managing Director. Morrison successfully brought about improvements in all parts of the production process; between 1915 and 1930 he increased the size of individual electrolytic cells by a factor of five, from 8,000 to 40,000 amperes. Soon after 1901, BAC built a second works for electrolytic reduction, at Kinlochleven in Argyllshire, where the primary design originated from Morrison. In the 1920s a third plant was erected at Fort William, in the lee of Ben Nevis, with hydroelectric generators providing some 75 MW. Alumina factories were constructed at Burntisland on the Firth of Forth and, in the 1930s, at Newport in Monmouthshire. Rolling mills were developed at Milton in Staffordshire, Warrington, and Falkirk in Stirlingshire, this last coming into use in the 1940s, by which time the company had a primary-metal output of more than 30,000 tonnes a year. Morrison was closely involved in all of these developments. He retired in 1946 as Deputy Chairman of BAC.
