Sholes was born on his parents' farm, of a family that had originally come from England. After leaving school at 14, he was apprenticed for four years to the local newspaper, the Danville Intelligencer. He moved with his parents to Wisconsin, where he followed his trade as journalist and printer, within a year becoming State Printer and taking charge of the House journal of the State Legislature. When he was 20 he left home and joined his brother in Madison, Wisconsin, on the staff of the Wisconsin Enquirer. After marrying, he took the editorship of the Southport Telegraph, until he became Postmaster of Southport. His experiences as journalist and postmaster drew him into politics and, in spite of the delicate nature of his health and personality, he served with credit as State Senator and in the State Assembly. In 1860 he moved to Milwaukee, where he became Editor of the local paper until President Lincoln offered him the post of Collector of Customs at Milwaukee.

That position at last gave Sholes time to develop his undoubted inventive talents. With a machinist friend, Samuel W.Soule, he obtained a patent for a paging machine and another two years later for a machine for numbering the blank pages of a book serially. At the small machine shop where they worked, there was a third inventor, Carlos Glidden. It was Glidden who suggested to Sholes that, in view of his numbering machine, he would be well equipped to develop a letter printing machine. Glidden drew Sholes's attention to an account of a writing machine that had recently been invented in London by John Pratt, and Sholes was so seized with the idea that he devoted the rest of his life to perfecting the machine. With Glidden and Soule, he took out a patent for a typewriter on June 1868 followed by two further patents for improvements. Sholes struggled unsuccessfully for five years to exploit his invention; his two partners gave up their rights in it and finally, on 1 March 1873, Sholes himself sold his rights to the Remington Arms Company for $12,000. With their mechanical skills and equipment, Remingtons were able to perfect the Sholes typewriter and put it on the market. This, the first commercially successful typewriter, led to a revolution not only in office work, but also in work for women, although progress was slow at first. When the New York Young Women's Christian Association bought six Remingtons in 1881 to begin classes for young women, eight turned up for the first les-son; and five years later it was estimated that there were 60,000 female typists in the USA. Sholes said, "I feel that I have done something for the women who have always had to work so hard. This will more easily enable them to earn a living."

Sholes continued his work on the typewriter, giving Remingtons the benefit of his results. His last patent was granted in 1878. Never very strong, Sholes became consumptive and spent much of his remaining nine years in the vain pursuit of health.

Carlson studied physics at the California Institute of Technology and in 1930 he took a research position at Bell Telephone Laboratories, but soon transferred to their patent department. To equip himself in this field, Carlson studied law, and in 1934 he became a patent attorney at P.R.Mallory \& Co., makers of electrical apparatus. He was struck by the difficulty in obtaining copies of documents and drawings; indeed, while still at school, he had encountered printing problems in trying to produce a newsletter for amateur chemists. He began experimenting with various light-sensitive substances, and by 1937 he had conceived the basic principles of xerography ("dry writing"), using the property of certain substances of losing an electrostatic charge when light impinges on them. His work for Mallory brought him into contact with the Battelle Memorial Institute, the world's largest non-profit research organization; their subsidiary, set up to develop promising ideas, took up Carlson's invention. Carlson received his first US patent for the process in 1940, with two more in 1942, and he assigned to Battelle exclusive patent rights in return for a share of any future proceeds. It was at Battelle that selenium was substituted as the light-sensitive material.

In 1946 the Haloid Company of Rochester, manufacturers of photographic materials and photocopying equipment, heard of the Xerox copier and, seeing it as a possible addition to their products, took out a licence to develop it commercially. The first Xerox Copier was tested during 1949 and put on the market the following year. The process soon began to displace older methods, such as Photostat, but its full impact on the public came in 1959 with the advent of the Xerox 914 Copier. It is fair to apply the overworked word "revolution" to the change in copying methods initiated by Carlson. He became a multimillionaire from his royalties and stock holding, and in his last years he was able to indulge in philanthropic activities.

He received his education at Dulwich College and in 1922 graduated with a BSc from University College, London. He had an early interest in the application of valve amplifiers, and after graduating he was employed by J.E.Hough, Edison Bell Works, to develop a line of radio-receiving equipment. However, he became interested in the mechanical (and later electrical) side of recording and from 1925 developed principles and equipment. In particular he developed capacitor microphones, not only for in-house work but also commercially, until the mid-1930s. The Edison Bell company did not survive the Depression and closed in 1933. Voigt founded his own company, Voigt Patents Ltd, concentrating on loudspeakers for cinemas and developing horn loudspeakers for domestic use. During the Second World War he continued to develop loudspeaker units and gramophone pick-ups, and in 1950 he emigrated to Toronto, Canada, but his company closed. Voigt taught electronics, and from 1960 to 1969 he was employed by the Radio Regulations Laboratory in Ottawa. After retirement he worked with theoretical cosmology and fundamental interactions.

Caro received vocational training as a dyer at the Gewerbeinstitut in Berlin from 1852, at the same time attending chemistry lectures at the university there. In 1855 he was hired as a colourist by a firm of calico printers in Mulheim an der Ruhr, where he was able to demonstrate the value of scientific training in solving practical problems. Two years later, the year after Perkin's discovery of aniline dyes, he was sent to England in order to learn the latest dyeing techniques. He took up a post an analytical chemist with the chemical firm Roberts, Dale \& Co. in Manchester; after finding a better way of synthesizing Perkin's mauve, he became a partner in the business. Caro was able to enlarge both his engineering experience and his chemical knowledge there, particularly by studying Hofmann's researches on the aniline dyes. He made several discoveries, including induline, Bismark brown and Martius yellow.

Like other German chemists, however, he found greater opportunities opening up in Germany, and in 1866 he returned to take up a post in Bunsen's laboratory in Heidelberg. In 1868 Caro obtained the important directorship of Badische Anilin-Soda- Fabrik (BASF), the first true industrial research organization and leading centre of dyestuffs research. A steady stream of commercial successes followed. In 1869, after Graebe and Liebermann had showed him their laboratory synthesis of the red dye alizarin, Caro went on to develop a cheaper and commercially viable method. During the 1870s he collaborated with Adolf von Baeyer to make methylene blue and related dyes, and then went on to the azo dyes. His work on indigo was important, but was not crowned with commercial success; that came in 1897 when his successor at BASF discovered a suitable process for producing indigo on a commercial scale. Caro had resigned his post in 1889, by which time he had made notable contributions to German supremacy in the fast-developing dyestuffs industry.

Soon after graduating from the Ecole des Mines at St-Etienne in 1910, Chevenard joined the Société de Commentry Fourchambault et Decazeville at their steelworks at Imphy, where he remained for the whole of his career. Imphy had for some years specialized in the production of nickel steels. From this venture emerged the first austenitic nickel-chromium steel, containing 6 per cent chromium and 22–4 per cent nickel and produced commercially in 1895. Most of the alloys required by Guillaume in his search for the low-expansion alloy Invar were made at Imphy. At the Imphy Research Laboratory, established in 1911, Chevenard conducted research into the development of specialized nickel-based alloys. His first success followed from an observation that some of the ferro-nickels were free from the low-temperature brittleness exhibited by conventional steels. To satisfy the technical requirements of Georges Claude, the French cryogenic pioneer, Chevenard was then able in 1912 to develop an alloy containing 55–60 per cent nickel, 1–3 per cent manganese and 0.2–0.4 per cent carbon. This was ductile down to −190°C, at which temperature carbon steel was very brittle.

By 1916 Elinvar, a nickel-iron-chromium alloy with an elastic modulus that did not vary appreciably with changes in ambient temperature, had been identified. This found extensive use in horology and instrument manufacture, and even for the production of high-quality tuning forks. Another very popular alloy was Platinite, which had the same coefficient of thermal expansion as platinum and soda glass. It was used in considerable quantities by incandescent-lamp manufacturers for lead-in wires. Other materials developed by Chevenard at this stage to satisfy the requirements of the electrical industry included resistance alloys, base-metal thermocouple combinations, magnetically soft high-permeability alloys, and nickel-aluminium permanent magnet steels of very high coercivity which greatly improved the power and reliability of car magnetos. Thermostatic bimetals of all varieties soon became an important branch of manufacture at Imphy.

During the remainder of his career at Imphy, Chevenard brilliantly elaborated the work on nickel-chromium-tungsten alloys to make stronger pressure vessels for the Haber and other chemical processes. Another famous alloy that he developed, ATV, contained 35 per cent nickel and 11 per cent chromium and was free from the problem of stress-induced cracking in steam that had hitherto inhibited the development of high-power steam turbines. Between 1912 and 1917, Chevenard recognized the harmful effects of traces of carbon on this type of alloy, and in the immediate postwar years he found efficient methods of scavenging the residual carbon by controlled additions of reactive metals. This led to the development of a range of stabilized austenitic stainless steels which were free from the problems of intercrystalline corrosion and weld decay that then caused so much difficulty to the manufacturers of chemical plant.

Chevenard soon concluded that only the nickel-chromium system could provide a satisfactory basis for the subsequent development of high-temperature alloys. The first published reference to the strengthening of such materials by additions of aluminium and/or titanium occurs in his UK patent of 1929. This strengthening approach was adopted in the later wartime development in Britain of the Nimonic series of alloys, all of which depended for their high-temperature strength upon the precipitated compound Ni3Al.

In 1936 he was studying the effect of what is now known as "thermal fatigue", which contributes to the eventual failure of both gas and steam turbines. He then published details of equipment for assessing the susceptibility of nickel-chromium alloys to this type of breakdown by a process of repeated quenching. Around this time he began to make systematic use of the thermo-gravimetrie balance for high-temperature oxidation studies.

Dickson was born in France of English and Scottish parents. As a young man of almost 19 years, he wrote in 1879 to Thomas Edison in America, asking for a job. Edison replied that he was not taking on new staff at that time, but Dickson, with his mother and sisters, decided to emigrate anyway. In 1883 he contacted Edison again, and was given a job at the Goerk Street laboratory of the Edison Electric Works in New York. He soon assumed a position of responsibility as Superintendent, working on the development of electric light and power systems, and also carried out most of the photography Edison required. In 1888 he moved to the Edison West Orange laboratory, becoming Head of the ore-milling department. When Edison, inspired by Muybridge's sequence photographs of humans and animals in motion, decided to develop a motion picture apparatus, he gave the task to Dickson, whose considerable skills in mechanics, photography and electrical work made him the obvious choice. The first experiments, in 1888, were on a cylinder machine like the phonograph, in which the sequence pictures were to be taken in a spiral. This soon proved to be impractical, and work was delayed for a time while Dickson developed a new ore-milling machine. Little progress with the movie project was made until George Eastman's introduction in July 1889 of celluloid roll film, which was thin, tough, transparent and very flexible. Dickson returned to his experiments in the spring of 1891 and soon had working models of a film camera and viewer, the latter being demonstrated at the West Orange laboratory on 20 May 1891. By the early summer of 1892 the project had advanced sufficiently for commercial exploitation to begin. The Kinetograph camera used perforated 35 mm film (essentially the same as that still in use in the late twentieth century), and the kinetoscope, a peep-show viewer, took fifty feet of film running in an endless loop. Full-scale manufacture of the viewers started in 1893, and they were demonstrated on a number of occasions during that year. On 14 April 1894 the first kinetoscope parlour, with ten viewers, was opened to the public in New York. By the end of that year, the kinetoscope was seen by the public all over America and in Europe. Dickson had created the first commercially successful cinematograph system. Dickson left Edison's employment on 2 April 1895, and for a time worked with Woodville Latham on the development of his Panoptikon projector, a projection version of the kinetoscope. In December 1895 he joined with Herman Casier, Henry N.Marvin and Elias Koopman to form the American Mutoscope Company. Casier had designed the Mutoscope, an animated-picture viewer in which the sequences of pictures were printed on cards fixed radially to a drum and were flipped past the eye as the drum rotated. Dickson designed the Biograph wide-film camera to produce the picture sequences, and also a projector to show the films directly onto a screen. The large-format images gave pictures of high quality for the period; the Biograph went on public show in America in September 1896, and subsequently throughout the world, operating until around 1905. In May 1897 Dickson returned to England and set up as a producer of Biograph films, recording, among other subjects, Queen Victoria's Diamond Jubilee celebrations in 1897, Pope Leo XIII in 1898, and scenes of the Boer War in 1899 and 1900. Many of the Biograph subjects were printed as reels for the Mutoscope to produce the "what the butler saw" machines which were a feature of fairgrounds and seaside arcades until modern times. Dickson's contact with the Biograph Company, and with it his involvement in cinematography, ceased in 1911.

Edward Geisler Herbert was educated at Nottingham High School in 1876–87, and at University College, London, in 1887–90, graduating with a BSc in Physics in 1889 and remaining for a further year to take an engineering course. He began his career as a premium apprentice at the Nottingham works of Messrs James Hill \& Co, manufacturers of lace machinery. In 1892 he became a partner with Charles Richardson in the firm of Richardson \& Herbert, electrical engineers in Manchester, and when this partnership was dissolved in 1895 he carried on the business in his own name and began to produce machine tools. He remained as Managing Director of this firm, reconstituted in 1902 as a limited liability company styled Edward G.Herbert Ltd, until his retirement in 1928. He was joined by Charles Fletcher (1868–1930), who as joint Managing Director contributed greatly to the commercial success of the firm, which specialized in the manufacture of small machine tools and testing machinery.

Around 1900 Herbert had discovered that hacksaw machines cut very much quicker when only a few teeth are in operation, and in 1902 he patented a machine which utilized this concept by automatically changing the angle of incidence of the blade as cutting proceeded. These saws were commercially successful, but by 1912, when his original patents were approaching expiry, Herbert and Fletcher began to develop improved methods of applying the rapid-saw concept. From this work the well-known Rapidor and Manchester saws emerged soon after the First World War. A file-testing machine invented by Herbert before the war made an autographic record of the life and performance of the file and brought him into close contact with the file and tool steel manufacturers of Sheffield. A tool-steel testing machine, working like a lathe, was introduced when high-speed steel had just come into general use, and Herbert became a prominent member of the Cutting Tools Research Committee of the Institution of Mechanical Engineers in 1919, carrying out many investigations for that body and compiling four of its Reports published between 1927 and 1933. He was the first to conceive the idea of the "tool-work" thermocouple which allowed cutting tool temperatures to be accurately measured. For this advance he was awarded the Thomas Hawksley Gold Medal of the Institution in 1926.

His best-known invention was the Pendulum Hardness Tester, introduced in 1923. This used a spherical indentor, which was rolled over, rather than being pushed into, the surface being examined, by a small, heavy, inverted pendulum. The period of oscillation of this pendulum provided a sensitive measurement of the specimen's hardness. Following this work Herbert introduced his "Cloudburst" surface hardening process, in which hardened steel engineering components were bombarded by steel balls moving at random in all directions at very high velocities like gaseous molecules. This treatment superhardened the surface of the components, improved their resistance to abrasion, and revealed any surface defects. After bombardment the hardness of the superficially hardened layers increased slowly and spontaneously by a room-temperature ageing process. After his retirement in 1928 Herbert devoted himself to a detailed study of the influence of intense magnetic fields on the hardening of steels.

Herbert was a member of several learned societies, including the Manchester Association of Engineers, the Institute of Metals, the American Society of Mechanical Engineers and the Institution of Mechanical Engineers. He retained a seat on the Board of his company from his retirement until the end of his life.

Although reared in a farming community, Lanston was able to develop his mechanical talent. After serving in the American Civil War he secured a clerkship in the Pensions Office in Washington, where he remained for twenty-two years. He studied law in his spare time and was called to the Bar. At the same time, he invented a whole variety of mechanical devices, many of which he patented. Around 1883 Lanston began taking an interest in machines for composing printers' type, probably stimulated by Ottmar Mergenthaler, who was then in Washington and working in this field. Four years' work were rewarded on 7 June 1887 by the grant of a patent, followed by three more, for a machine "to produce justified lines of type". The machine, the Monotype, consisted of two components: first a keyboard unit produced a strip of paper tape with holes punched in patterns corresponding to the characters required; this tape controlled the matrices in the caster, the second and "hot metal" component, from which types were ejected singly and fed to an assembly point until a complete line of type had been formed. Lanston resigned his post and set up the Lanston Type Machine Company in Washington. He laboured for ten years to convert the device defined in his patents into a machine that could be made and used commercially. In 1897 the perfected Monotype appeared. The company was reorganized as the Lanston Monotype Manufacturing Company of Philadelphia, and Lanston devoted himself to promoting and improving the machine. Monotype, with Mergenthaler's Linotype, steadily supplanted hand-setting and the various inadequate mechanical methods that were then in use, and by the 1920s they reigned supreme, until the 1960s, when they themselves began to be superseded by computer-controlled photosetting methods.

Werner von Siemens was the eldest of a large family and after the early death of his parents took his place at its head. He served in the Prussian artillery, being commissioned in 1839, after which he devoted himself to the study of chemistry and physics. In 1847 Siemens and J.G. Halske formed a company, Telegraphen-Bauanstalt von Siemens und Halske, to manufacture a dial telegraph which they had developed from an earlier instrument produced by Charles Wheatstone. In 1848 Siemens obtained his discharge from the army and he and Halske constructed the first long-distance telegraph line on the European continent, between Berlin and Frankfurt am Main.

Werner von Siemens's younger brother, William Siemens, had settled in Britain in 1844 and was appointed agent for the Siemens \& Halske company in 1851. Later, an English subsidiary company was formed, known from 1865 as Siemens Brothers. It specialized in manufacturing and laying submarine telegraph cables: the specialist cable-laying ship Faraday, launched for the purpose in 1874, was the prototype of later cable ships and in 1874–5 laid the first cable to run direct from the British Isles to the USA. In charge of Siemens Brothers was another brother, Carl, who had earlier established a telegraph network in Russia.

In 1866 Werner von Siemens demonstrated the principle of the dynamo in Germany, but it took until 1878 to develop dynamos and electric motors to the point at which they could be produced commercially. The following year, 1879, Werner von Siemens built the first electric railway, and operated it at the Berlin Trades Exhibition. It comprised an oval line, 300 m (985 it) long, with a track gauge of 1 m (3 ft 3 1/2 in.); upon this a small locomotive hauled three small passenger coaches. The locomotive drew current at 150 volts from a third rail between the running rails, through which it was returned. In four months, more than 80,000 passengers were carried. The railway was subsequently demonstrated in Brussels, and in London, in 1881. That same year Siemens built a permanent electric tramway, 1 1/2 miles (2 1/2 km) long, on the outskirts of Berlin. In 1882 in Berlin he tried out a railless electric vehicle which drew electricity from a two-wire overhead line: this was the ancestor of the trolleybus.

In the British Isles, an Act of Parliament was obtained in 1880 for the Giant's Causeway Railway in Ireland with powers to work it by "animal, mechanical or electrical power"; although Siemens Brothers were electrical engineers to the company, of which William Siemens was a director, delays in construction were to mean that the first railway in the British Isles to operate regular services by electricity was that of Magnus Volk.
