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.

Coolidge obtained his BS from the Massachusetts Institute of Technology (MIT) in 1896, and his PhD (physics) from the University of Leipzig in 1899. He was appointed Assistant Professor of Physics at MIT in 1904, and in 1905 he joined the staff of the General Electric Company's research laboratory at Schenectady. In 1905 Schenectady was trying to make tungsten-filament lamps to counter the competition of the tantalum-filament lamps then being produced by their German rival Siemens. The first tungsten lamps made by Just and Hanaman in Vienna in 1904 had been too fragile for general use. Coolidge and his life-long collaborator, Colin G. Fink, succeeded in 1910 by hot-working directly dense sintered tungsten compacts into wire. This success was the result of a flash of insight by Coolidge, who first perceived that fully recrystallized tungsten wire was always brittle and that only partially work-hardened wire retained a measure of ductility. This grasped, a process was developed which induced ductility into the wire by hot-working at temperatures below those required for full recrystallization, so that an elongated fibrous grain structure was progressively developed. Sintered tungsten ingots were swaged to bar at temperatures around 1,500°C and at the end of the process ductile tungsten filament wire was drawn through diamond dies around 550°C. This process allowed General Electric to dominate the world lamp market. Tungsten lamps consumed only one-third the energy of carbon lamps, and for the first time the cost of electric lighting was reduced to that of gas. Between 1911 and 1914, manufacturing licences for the General Electric patents had been granted for most of the developed work. The validity of the General Electric monopoly was bitterly contested, though in all the litigation that followed, Coolidge's fibering principle was upheld. Commercial arrangements between General Electric and European producers such as Siemens led to the name "Osram" being commonly applied to any lamp with a drawn tungsten filament. In 1910 Coolidge patented the use of thoria as a particular additive that greatly improved the high-temperature strength of tungsten filaments. From this development sprang the technique of "dispersion strengthening", still being widely used in the development of high-temperature alloys in the 1990s. In 1913 Coolidge introduced the first controllable hot-cathode X-ray tube, which had a tungsten target and operated in vacuo rather than in a gaseous atmosphere. With this equipment, medical radiography could for the first time be safely practised on a routine basis. During the First World War, Coolidge developed portable X-ray units for use in field hospitals, and between the First and Second World Wars he introduced between 1 and 2 million X-ray machines for cancer treatment and for industrial radiography. He became Director of the Schenectady laboratory in 1932, and from 1940 until 1944 he was Vice-President and Director of Research. After retirement he was retained as an X-ray consultant, and in this capacity he attended the Bikini atom bomb trials in 1946. Throughout the Second World War he was a member of the National Defence Research Committee.

Deville was the son of a prosperous shipowner with diplomatic duties in the Virgin Islands. With his elder brother Charles, who later became a distinguished physicist, he was sent to Paris to be educated. He took his degree in medicine in 1843, but before that he had shown an interest in chemistry, due particularly to the lectures of Thenard. Two years later, with Thenard's influence, he was appointed Professor of Chemistry at Besançon. In 1851 he was able to return to Paris as Professor at the Ecole Normale Supérieure. He remained there for the rest of his working life, greatly improving the standard of teaching, and his laboratory became one of the great research centres of Europe. His first chemical work had been in organic chemistry, but he then turned to inorganic chemistry, specifically to improve methods of producing the new and little-known metal aluminium. Essentially, the process consisted of forming sodium aluminium trichloride and reducing it with sodium to metallic aluminium. He obtained sodium in sufficient quantity by reducing sodium carbonate with carbon. In 1855 he exhibited specimens of the metal at the Paris Exhibition, and the same year Napoleon III asked to see them, with a view to using it for breastplates for the Army and for spoons and forks for State banquets. With the resulting government support, he set up a pilot plant at Jarvel to develop the process, and then set up a small company, the Société d'Aluminium at Nan terre. This raised the output of this attractive and useful metal, so it could be used more widely than for the jewellery to which it had hitherto been restricted. Large-scale applications, however, had to await the electrolytic process that began to supersede Deville's in the 1890s. Deville extended his sodium reduction method to produce silicon, boron and the light metals magnesium and titanium. His investigations into the metallurgy of platinum revolutionized the industry and led in 1872 to his being asked to make the platinum-iridium (90–10) alloy for the standard kilogram and metre. Deville later carried out important work in high-temperature chemistry. He grieved much at the death of his brother Charles in 1876, and his retirement was forced by declining health in 1880; he did not survive for long.

Waterhouse spent most of his career in the Indian Army. In 1861–2 he was commissioned to photograph the tribes of central India, and over the next few years visited many parts of the subcontinent. In November 1866, after working for five months in the Great Trigonometrical Survey learning the process of photozincography (an early photomechanical process used chiefly for map making), he took charge of photographic operations at the Surveyor-General's office in Calcutta, a post he held until retiring in 1897. During this time he developed many improvements in the photomechanical methods used for reproduction in his office. He also experimented with methods of colour-sensitizing photographic materials, experimenting with eosine dye and publishing in 1875 the fact that this made silver halide salts sensitive to yellow light. He also discovered that gelatine dry plates could be made sensitive to red and infra-red illumination by treatment with alizarine blue solution.

He continued his researches upon his retirement and return to England in 1897, and made a special study of the early history of the photographic process. His work on dye sensitizing brought him the Progress Medal of the Royal Photographic Society, and the Vienna Photographic Society awarded him the Voigtländer Medal for researches in scientific photography. One invention often erroneously attributed to him is the Waterhouse stop, the use of a series of perforated plates as a means of adjusting the aperture of a photographic lens. This was described in 1858 by a John Waterhouse, being his only contribution to photography.

After obtaining BSc and MSc degrees in physics at Brown University in 1896 and 1897, respectively, Cady went to Berlin, obtaining his PhD in 1900. Returning to the USA he initially worked for the US Coast and Geodetic Survey, but in 1902 he took up a post at the Wesleyan University, Connecticut, remaining as Professor of Physics from 1907 until his retirement in 1946. During the First World War he became interested in piezo-electricity as a result of attending a meeting on techniques for detecting submarines, and after the war he continued to work on the use of piezo-electricity as a transducer for generating sonar beams. In the process he discovered that piezo-electric materials, such as quartz, exhibited high-stability electrical resonance, and in 1921 he produced the first working piezo-electric resonator. This idea was subsequently taken up by George Washington Pierce and others, resulting in very stable oscillators and narrow-band filters that are widely used in the 1990s in radio communications, electronic clocks and watches.

Internationally known for his work, Cady retired from his professorship in 1946, but he continued to work for the US Navy. From 1951 to 1955 he was a consultant and research associate at the California Institute of Technology, after which he returned to Providence to continue research at Brown, filing his last patent (one of over fifty) at the age of 93 years.

Hunter arrived in England in 1902, the seventh in the succession of New Zealand students nominated for the 1851 Exhibition science research scholarships (the third, in 1894, having been Ernest Rutherford). He intended to study the metallurgy of tellurides at the Royal School of Mines, but owing to the death of the professor concerned, he went instead to University College London, where his research over two years involved the molecular aggregation of liquified gases. In 1904–5 he spent a third year in Göttingen, Paris and Karlsruhe. Hunter then moved to the USA, beginning work in 1906 with the General Electric Company in Schenectady. His experience with titanium came as part of a programme to try to discover satisfactory lamp-filament materials. He and his colleagues achieved more success in producing moderately pure titanium than previous workers had done, but found the metal's melting temperature inadequate. However, his research formed the basis for the "Hunter sodium process", a modern method for producing commercial quantities of titanium. In 1908 he was appointed Assistant Professor of Electrochemistry and Physics at Rensselaer Polytechnic Institute in Troy, New York, where he was to remain until his retirement in 1949 as Dean Emeritus. In the 1930s he founded and headed the Institute's Department of Metallurgical Engineering. As a consultant, he was associated with the development of Invar, Managanin and Constantan alloys.

He graduated from the Dover Academy (Delaware) in 1882 and was apprenticed in a machine-repair firm in Philadelphia and studied in evening classes at the Spring Garden Institute. In 1888 he took employment in a small Philadelphia machine shop owned by Andrew Scull, specializing in repair and bookbinding machinery. After travels in the western part of the US, in 1891 he became a partner in Scull \& Johnson, Manufacturing Machinists, and established a further company, the New Jersey Wire Stitching Machine Company. He bought out Andrew Scull's interest in October 1894 (the last instalment being paid in 1897) and became an independent general machinist. In 1896 he had perfected a spring motor for the Berliner flat-disc gramophone, and he started experimenting with a more direct method of recording in a spiral groove: that of cutting in wax. Co-operation with Berliner eventually led to the incorporation of the Victor Talking Machine Company in 1901. The innumerable court cases stemming from the fact that so many patents for various elements in sound recording and reproduction were in very many hands were brought to an end in 1903 when Johnson was material in establishing cross-licencing agreements between Victor, Columbia Graphophone and Edison to create what is known as a patent pool. Early on, Johnson had a thorough experience in all matters concerning the development and manufacture of both gramophones and records. He made and patented many major contributions in all these fields, and his approach was very business-like in that the contribution to cost of each part or process was always a decisive factor in his designs. This attitude was material in his consulting work for the sister company, the Gramophone Company, in London before it set up its own factories in 1910. He had quickly learned the advantages of advertising and of providing customers with durable equipment and records. This motivation was so strong that Johnson set up a research programme for determining the cause of wear in records. It turned out to depend on groove profile, and from 1911 one particular profile was adhered to and processes for transforming the grooves of valuable earlier records were developed. Without precise measuring instruments, he used the durability as the determining factor. Johnson withdrew more and more to the role of manager, and the Victor Talking Machine Company gained such a position in the market that the US anti-trust legislation was used against it. However, a generation change in the Board of Directors and certain erroneous decisions as to product line started a decline, and in February 1926 Johnson withdrew on extended sick leave: these changes led to the eventual sale of Victor. However, Victor survived due to the advent of radio and the electrification of replay equipment and became a part of Radio Corporation of America. In retirement Johnson took up various activities in the arts and sciences and financially supported several projects; his private yacht was used in 1933 in work with the Smithsonian Institution on a deep-sea hydrographie and fauna-collecting expedition near Puerto Rico.

Within the long tradition of celebrated teachers at the Mining Academy in Freiberg, Kegel can be considered as probably the last professor teaching the science of mining who was able to cover all the different disciplines. As was the case with a number of his predecessors, he was able to combine theoretical research work with the teaching of students and to support his theories with the practical experience of industry. He has apprenticed at the Mansfeld copper mines, went to the School of Mines at Eisleben (1896–8), worked as an engineer with various mining companies and thereafter became a scholar of the Berlin Mining Academy (1901–4). For twelve years he taught at the Bochum School of Mining until, in 1918, he was appointed Professor of Mining at Freiberg. There, one year later, as a new approach, he introduced lectures on brown-coal mining and mineral economics. He remained Professor at Freiberg until his first retirement in 1941, although he was active again between 1945 and 1951.

In 1924 Kegel took over a department at the State Research Institute for Brown Coal in Freiberg which he extended into the Institute for Briquetting. In this field his main achievement lies in the initially questioned theory that producing briquettes from lignite is a molecular process rather than the result of bituminous factors. This perception, among others, led Rammler to produce coke from lignite in 1951. Kegel's merits result from having established all the aspects of mining and using lignite as an independent subdiscipline of mining science, based on substantial theories and an innovative understanding of applied technologies.

Orphaned when his parents died of cholera, at the age of 14 he was taken by his elder sister to live in Marcilly-le-Hayer. Apprenticed to a joiner, he was also interested in chemistry and physics, but his great love was drawing and painting. The leading water-colourist Auguste Constantin took him into his Paris home as an apprentice and taught him the whole business of painting. He was able to earn his living as a sign-painter, and numbered among his clients several photographers. This led to an interest in photography, which caused him to abandon the safe trade of sign-painter for that of photographer.

Lumière took a post with a photographer in Besançon in 1862. He set up business on his own account in 1865 and moved to Lyons c.1870, joining his friend and fellow photographer Emile Lebeau. The business prospered; in 1879 he installed an electricity generator in his studio to run the newly invented Van de Weyde electric arc lamp, permitting portraiture in all weathers and at all times. With the arrival of the dry-plate process c. 1880, the Lumière business looked to employ the new medium. His second son, Louis Lumière (b. 5 October 1864 Besançon, France; d. 6 June 1948 Bandol, France; see under Lumière, Auguste), fresh from college, experimented with emulsions with which his 12-year-old sister coated glass plates. While still running the studio, Antoine started marketing the plates, which were the first to be made in France, and production was soon up to 4,000 plates a day. Under his guidance A.Lumière et ses Fils acquired a worldwide reputation for the quality and originality of its products.

After his retirement from business, when he handed it over to his sons, Auguste (see Lumière, Auguste) and Louis, he took up painting again and successfully exhibited in several Salons. He was a Chevalier of the Légion d'honneur, a recognition of his participation in the 1893 World's Colombian Exposition in Chicago.

Poncelet studied mathematics at the Ecole Polytechnique in Paris from 1807 to 1810. He joined the Army, gaining admission to the Corps of Engineers. He worked on the fortifications on the Isle of Walcheren in Holland, and in 1812 he found himself on the Russian front, engulfed in the disastrous defeat of the French at Krasnoi. Poncelet was left for dead on the field, but he was found by the Russians and taken to Saratov, where he was imprisoned for two years. He had ample opportunity there to ponder mathematical problems, a mental process from which stemmed his pioneering advances in projective geometry.

After his release he returned to this native city of Metz, where he undertook routine military engineering and teaching tasks. These left him time to pursue his mathematical studies in projective geometry. This bore fruit in a series of publications, most notably the first volume of his Traité des propriétés projectives des figures (1822, Paris), the first book to be devoted to the new discipline of projective geometry. With his election to the Académie des Sciences in 1834, Poncelet moved to Paris and devoted much of his time to developing courses in applied mechanics in the Faculty of Science, resulting in a number of books, especially the Introduction à la mécanique industrielle, physique ou expérimentale (1841, Paris: Metz). In 1848 he had attained the rank of general and was made Commandant of the Ecole Polytechnique, a post he held for two years. After his retirement in 1850 he was deeply involved in the industrial machines and tools division at both the Great Exhibition in London in 1851 and the similar exhibition in Paris in 1855.

Most of Poncelet's work in applied mechanics and technology was conceived during the period 1825–40. His technological innovations were centred on hydraulic engineering, and in 1826 he invented an inward-flow turbine. At the same time he directed his attention to the vertical undershot water-wheel, with wooden blades set radially and substituted curved metal blades: he used tight-fitting masonry and floors in the wheel pits so that all the water would be swept into the spaces between the blades. In addition, he ensured that the water flowing from the blades fell clear of the wheel and did not run in tail water. This greatly improved the efficiency of the water-wheel.
