SUBJECT AREA: Mining and extraction technology[br]b. 1845 Dukinfield, Cheshire, Englandd. 1 October 1921 Pontefract, Yorkshire, England[br]English colliery manager, pioneer in machine-holing and the safety of mines.[br]After Menzies conceived his idea of breaking off coal with machines in 1761, many inventors subsequently followed his proposals through into the practice of underground working. More than one century later, Garforth became one of the principal pioneers of machine-holing combined with the longwall method of working in order to reduce production costs and increase the yield of coal. Having been appointed agent to Pope \& Pearson's Collieries, West Yorkshire, in 1879, of which company he later became Managing Director and Chairman, he gathered a great deal of experience with different methods of cutting coal. The first disc machine was exhibited in London as early as 1851, and ten years later a pick machine was invented. In 1893 he introduced an improved type of deep undercutting machine, his "diamond" disc coal-cutter, driven by compressed air, which also became popular on the European continent.Besides the considerable economic advantages it created, the use of machinery for mining coal increased the safety of working in hard and thin seams. The improvement of safety in mining technology was always his primary concern, and as a result of his inventions and his many publications he became the leading figure in the British coal mining industry at the beginning of the twentieth century; safety lamps still carry his name. In 1885 he invented a firedamp detector, and following a severe explosion in 1886 he concentrated on coal-dust experiments. From the information he obtained of the effect of stone-dust on a coal-dust explosion he proposed the stone-dust remedy to prevent explosions of coal-dust. As a result of discussions which lasted for decades and after he had been entrusted with the job of conducting the British coal-dust experiments, in 1921 an Act made it compulsory in all mines which were not naturally wet throughout to treat all roads with incombustible dust so as to ensure that the dust always consisted of a mixture containing not more than 50 per cent combustible matter. In 1901 Garforth erected a surface gallery which represented the damaged roadways of a mine and could be filled with noxious fumes to test self-contained breathing apparata. This gallery formed the model from which all the rescue-stations existing nowadays have been developed.[br]Principal Honours and DistinctionsKnighted 1914.

* * *= accomplish, design (for/to), be up to, cause, conduct, do, devise, produce, render, compose, make, get (a)round to, make out, get round to, brew.Ex: If a library prefers to simplify records in particular areas, this can usually be accomplished by not entering particular types of information.
Ex: In lists designed for international use a symbolic notation instead of textual notes may be used.Ex: When I saw what he was up to, I drew back for a punch and hit him so hard on the nose that he fell on his back and lay there for some time, so that his wife stood over him and cried out 'Mercy! You've done my husband in!'.Ex: As usage of the language causes terms to become anachronistic, or as increases in our level of awareness reveal undesirable connotations, we seek to change subject heading terms.Ex: Obviously, this tagging must be conducted manually.Ex: In all these cases where scientists studied what crafstmen knew how to do the resulting benefits have accrued to science not to technology.Ex: Special classification schemes are generally devised for an application in which no major general scheme is suitable.Ex: The present OCLC system does not produce catalog cards in sets, but if it did it could produce over 6,000 different sets for one title.Ex: So strongly was it felt by proponents of change that just such unconscious biases rendered libraries 'part of the problem, instead of the solution'.Ex: There have never been any attempts to compose a bibliography of US government documents relating to international law.Ex: This concept comes mainly from the military, where a designated number of troops make a squad, a platoon, a regiment, etc..Ex: The article is entitled 'A list of lists of Web sites to check out: getting organized and getting around to it are two different things'.Ex: The cards for those headings should be removed from the index and new cards made out if necessary.Ex: The government have been making noises about it for some time but haven't quite got round to it.Ex: The goddess owned a potent magick cauldron in which she planned to brew a special liquid for her ugly son.* acceder haciendo clic = click.* acusación + hacer = accusation +

24 Deville, Henri Etienne Sainte-Claire
SUBJECT AREA: Metallurgy[br]b. 11 March 1818 St Thomas, Virgin Islandsd. 1 July 1881 Boulogne-sur-Seine, France[br]French chemist and metallurgist, pioneer in the large-scale production of aluminium and other light metals.[br]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.[br]BibliographyDeville published influential books on aluminium and platinum; these and all his publications are listed in the bibliography in the standard biography by J.Gray, 1889, Henri Sainte-Claire Deville: sa vie et ses travaux, Paris.Further ReadingM.Daumas, 1949, "Henri Sainte-Claire Deville et les débuts de l'industrie de l'aluminium", Rev.Hist.Sci 2:352–7.J.C.Chaston, 1981, "Henri Sainte-Claire Deville: his outstanding contributions to the chemistry of the platinum metals", Platinum Metals Review 25:121–8.LRDBiographical history of technology > Deville, Henri Etienne Sainte-Claire

25 Barsanti, Eugenio
SUBJECT AREA: Steam and internal combustion engines[br]b. 1821 Italyd. 1864 Liège, Belgium[br]Italian co-inventor of the internal combustion engine; lecturer in mechanics and hydraulics.[br]A trained scientist and engineer, Barsanti became acquainted with a distinguished engineer, Felice Matteucci, in 1851. Their combined talents enabled them to produce a number of so-called free-piston atmospheric engines from 1854 onwards. Using a principle demonstrated by the Swiss engineer Isaac de Rivaz in 1827, the troublesome explosive shocks encountered by other pioneers were avoided. A piston attached to a long toothed rack was propelled from beneath by the expansion of burning gas and allowed unrestricted movement. A resulting partial vacuum enabled atmospheric pressure to return the piston and produce the working stroke. Electric ignition was a feature of all the Italian engines.With many successful applications, a company was formed in 1860. A 20 hp (15 kW) engine stimulated much interest. Attempts by John Cockerill of Belgium to mass-produce small power units of up to 4 hp (3 kW) came to an abrupt end; during the negotiations Barsanti contracted typhoid fever and later died. The project was abandoned, but the working principle of the Italian engine was used successfully in the Otto-Langen engine of 1867.[br]Bibliography13 May 1854, British Provisional Patent no. 1,072 (the Barsanti and Matteucci engine).12 June 1857, British patent no. 1,655 (contained many notable improvements to the design).Further ReadingThe Engineer (1858) 5:73–4 (for an account of the Italian engine).Vincenzo Vannacci, 1955, L'invenzione del motore a scoppio realizzota dai toscani Barsanti e Matteucci 1854–1954, Florence.KAB -
26 Brayton, George Bailey
SUBJECT AREA: Steam and internal combustion engines[br]b. 1839 Rhode Island, USAd. 1892 Leeds, England[br]American engineer, inventor of gas and oil engines.[br]During the thirty years prior to his death, Brayton devoted considerable effort to the development of internal-combustion engines. He designed the first commercial gas engine of American origin in 1872. An oil-burning engine was produced in 1875. An aptitude for mechanical innovation became apparent whilst he was employed at the Exeter Machine Works, New Hampshire, where he developed a successful steam generator for use in domestic and industrial heating systems. Brayton engines were distinguished by the method of combustion. A pressurized air-fuel mixture from a reservoir was ignited as it entered the working cylinder—a precursor of the constant-pressure cycle. A further feature of these early engines was a rocking beam. There exist accounts of Brayton engines fitted into river craft, and of one in a carriage which operated for a few months in 1872–3. However, the appearance of the four-stroke Otto engine in 1876, together with technical problems associated with backfiring into the fuel reservoir, prevented large-scale acceptance of the Brayton engine. Although Thompson Sterne \& Co. of Glasgow became licensees, the engine failed to gain usage in Britain. A working model of Brayton's gas engine is exhibited in the Museum of History and Technology in Washington, DC.[br]Bibliography1872, US patent no. 125,166 (Brayton gas engine).July 1890, British patent no. 11,062 (oil engine; under patent agent W.R.Lake).Further ReadingD.Clerk, 1895, The Gas and Oil Engine, 6th edn, London, pp. 152–62 (includes a description and report of tests carried out on a Brayton engine).KAB -
27 Brown, Samuel
SUBJECT AREA: Steam and internal combustion engines[br]b. unknownd. 1849 England[br]English cooper, inventor of a gas vacuum engine.[br]Between the years 1823 and 1833, Brown achieved a number of a firsts as a pioneer of internal-combustion engines. In 1824 he built a full-scale working model of a pumping engine; in 1826, a vehicle fitted with a gas vacuum engine ascended Shooters Hill in Kent; and in 1827 he conducted trials of a motor-driven boat on the Thames that were witnessed by Lords of the Admiralty. The principle of Brown's engine had been demonstrated by Cecil in 1820. A burning gas flame was extinguished within a closed cylinder, creating a partial vacuum; atmospheric pressure was then utilized to produce the working stroke. By 1832 a number of Brown's engines in use for pumping water were reported, the most notable being at Croydon Canal. However, high fuel consumption and running costs prevented a wide acceptance of Brown's engines, and a company formed in 1825 was dissolved only two years later. Brown continued alone with his work until his death.[br]Bibliography1823, British patent no. 4,874 (gas vacuum engine).1826, British patent no. 5,350 (improved gas vacuum engine).1846, British patent no. 11,076, "Improvements in Gas Engines and in Propelling Carriages and Vessels" (no specification was enrolled).Further ReadingVarious discussions of Brown's engines can be found in Mechanics Magazine (1824) 2:360, 385; (1825) 3:6; (1825) 4:19, 309; (1826) 5:145; (1826) 6:79; (1827) 7:82–134; (1832) 17:273.The Engineer 182:214.A.K.Bruce, Samuel Brown and the Gas Engine.Dugald Clerk, 1895, The Gas and Oil Engine, 6th edn, London, pp. 2–3.KAB -
28 Coolidge, William David
[br]b. 23 October 1873 Hudson, Massachusetts, USAd. 3 February 1975 New York, USA[br]American physicist and metallurgist who invented a method of producing ductile tungsten wire for electric lamps.[br]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.[br]Bibliography1965, "The development of ductile tungsten", Sorby Centennial Symposium on the History of Metallurgy, AIME Metallurgy Society Conference, Vol. 27, ed.

29 Davis, Robert Henry
SUBJECT AREA: Ports and shipping[br]b. 6 June 1870 London, Englandd. 29 March 1965 Epsom, Surrey, England[br]English inventor of breathing, diving and escape apparatus.[br]Davis was the son of a detective with the City of London police. At the age of 11 he entered the employment of Siebe, Gorman \& Co., manufacturers of diving and other safety equipment since 1819, at their Lambeth works. By good fortune, his neat handwriting attracted the notice of Mr Gorman and he was transferred to work in the office. He studied hard after working hours and rose steadily in the firm. In his twenties he was promoted to Assistant Manager, then General Manager, Managing Director and finally Governing Director. He retired in 1960, having been made Life President the previous year, and continued to attend the office regularly until May 1964.Davis's entire career was devoted to research and development in the firm's special field. In 1906 he perfected the first practicable oxygen-breathing apparatus for use in mine rescue; it was widely adopted and with modifications was still in use in the 1990s. With Professor Leonard Hill he designed a deep-sea diving-bell incorporating a decompression chamber. He also invented an oxygen-breathing apparatus and heated apparel for airmen flying at high altitudes.Immediately after the first German gas attacks on the Western Front in April 1915, Davis devised a respirator, known as the stocking skene or veil mask. He quickly organized the mass manufacture of this device, roping in members of his family and placing the work in the homes of Lambeth: within 48 hours the first consignment was being sent off to France.He was a member of the Admiralty Deep Sea Diving Committee, which in 1933 completed tables for the safe ascent of divers with oxygen from a depth of 300 ft (91 m). They were compiled by Davis in conjunction with Professors J.B.S.Haldane and Leonard Hill and Captain G.C.Damant, the Royal Navy's leading diving expert. With revisions these tables have been used by the Navy ever since. Davis's best-known invention was first used in 1929: the Davis Submarine Escape Apparatus. It became standard equipment on submarines until it was replaced by the Built-in Breathing System, which the firm began manufacturing in 1951.The firm's works were bombed during the Second World War and were re-established at Chessington, Surrey. The extensive research facilities there were placed at the disposal of the Royal Navy and the Admiralty Experimental Diving Unit. Davis worked with Haldane and Hill on problems of the underwater physiology of working divers. A number of inventions issued from Chessington, such as the human torpedo, midget submarine and human minesweeper. In the early 1950s the firm helped to pioneer the use of underwater television to investigate the sinking of the submarine Affray and the crashed Comet jet airliners.[br]Principal Honours and DistinctionsKnighted 1932.BibliographyDavis was the author of several manuals on diving including Deep Sea Diving and Submarine Operations and Breathing in Irrespirable Atmospheres.

30 Ford, Henry
[br]b. 30 July 1863 Dearborn, Michigan, USAd. 7 April 1947 Dearborn, Michigan, USA[br]American pioneer motor-car maker and developer of mass-production methods.[br]He was the son of an Irish immigrant farmer, William Ford, and the oldest son to survive of Mary Litogot; his mother died in 1876 with the birth of her sixth child. He went to the village school, and at the age of 16 he was apprenticed to Flower brothers' machine shop and then at the Drydock \& Engineering Works in Detroit. In 1882 he left to return to the family farm and spent some time working with a 1 1/2 hp steam engine doing odd jobs for the farming community at $3 per day. He was then employed as a demonstrator for Westinghouse steam engines. He met Clara Jane Bryant at New Year 1885 and they were married on 11 April 1888. Their only child, Edsel Bryant Ford, was born on 6 November 1893.At that time Henry worked on steam engine repairs for the Edison Illuminating Company, where he became Chief Engineer. He became one of a group working to develop a "horseless carriage" in 1896 and in June completed his first vehicle, a "quadri cycle" with a two-cylinder engine. It was built in a brick shed, which had to be partially demolished to get the carriage out.Ford became involved in motor racing, at which he was more successful than he was in starting a car-manufacturing company. Several early ventures failed, until the Ford Motor Company of 1903. By October 1908 they had started with production of the Model T. The first, of which over 15 million were built up to the end of its production in May 1927, came out with bought-out steel stampings and a planetary gearbox, and had a one-piece four-cylinder block with a bolt-on head. This was one of the most successful models built by Ford or any other motor manufacturer in the life of the motor car.Interchangeability of components was an important element in Ford's philosophy. Ford was a pioneer in the use of vanadium steel for engine components. He adopted the principles of Frederick Taylor, the pioneer of time-and-motion study, and installed the world's first moving assembly line for the production of magnetos, started in 1913. He installed blast furnaces at the factory to make his own steel, and he also promoted research and the cultivation of the soya bean, from which a plastic was derived.In October 1913 he introduced the "Five Dollar Day", almost doubling the normal rate of pay. This was a profit-sharing scheme for his employees and contained an element of a reward for good behaviour. About this time he initiated work on an agricultural tractor, the "Fordson" made by a separate company, the directors of which were Henry and his son Edsel.In 1915 he chartered the Oscar II, a "peace ship", and with fifty-five delegates sailed for Europe a week before Christmas, docking at Oslo. Their objective was to appeal to all European Heads of State to stop the war. He had hoped to persuade manufacturers to replace armaments with tractors in their production programmes. In the event, Ford took to his bed in the hotel with a chill, stayed there for five days and then sailed for New York and home. He did, however, continue to finance the peace activists who remained in Europe. Back in America, he stood for election to the US Senate but was defeated. He was probably the father of John Dahlinger, illegitimate son of Evangeline Dahlinger, a stenographer employed by the firm and on whom he lavished gifts of cars, clothes and properties. He became the owner of a weekly newspaper, the Dearborn Independent, which became the medium for the expression of many of his more unorthodox ideas. He was involved in a lawsuit with the Chicago Tribune in 1919, during which he was cross-examined on his knowledge of American history: he is reputed to have said "History is bunk". What he actually said was, "History is bunk as it is taught in schools", a very different comment. The lawyers who thus made a fool of him would have been surprised if they could have foreseen the force and energy that their actions were to release. For years Ford employed a team of specialists to scour America and Europe for furniture, artefacts and relics of all kinds, illustrating various aspects of history. Starting with the Wayside Inn from South Sudbury, Massachusetts, buildings were bought, dismantled and moved, to be reconstructed in Greenfield Village, near Dearborn. The courthouse where Abraham Lincoln had practised law and the Ohio bicycle shop where the Wright brothers built their first primitive aeroplane were added to the farmhouse where the proprietor, Henry Ford, had been born. Replicas were made of Independence Hall, Congress Hall and the old City Hall in Philadelphia, and even a reconstruction of Edison's Menlo Park laboratory was installed. The Henry Ford museum was officially opened on 21 October 1929, on the fiftieth anniversary of Edison's invention of the incandescent bulb, but it continued to be a primary preoccupation of the great American car maker until his death.Henry Ford was also responsible for a number of aeronautical developments at the Ford Airport at Dearborn. He introduced the first use of radio to guide a commercial aircraft, the first regular airmail service in the United States. He also manufactured the country's first all-metal multi-engined plane, the Ford Tri-Motor.Edsel became President of the Ford Motor Company on his father's resignation from that position on 30 December 1918. Following the end of production in May 1927 of the Model T, the replacement Model A was not in production for another six months. During this period Henry Ford, though officially retired from the presidency of the company, repeatedly interfered and countermanded the orders of his son, ostensibly the man in charge. Edsel, who died of stomach cancer at his home at Grosse Point, Detroit, on 26 May 1943, was the father of Henry Ford II. Henry Ford died at his home, "Fair Lane", four years after his son's death.[br]Bibliography1922, with S.Crowther, My Life and Work, London: Heinemann.Further ReadingR.Lacey, 1986, Ford, the Men and the Machine, London: Heinemann.

31 Goldmark, Peter Carl
[br]b. 2 December 1906 Budapest, Hungaryd. 7 December 1977 Westchester Co., New York, USA[br]Austro-Hungarian engineer who developed the first commercial colour television system and the long-playing record.[br]After education in Hungary and a period as an assistant at the Technische Hochschule, Berlin, Goldmark moved to England, where he joined Pye of Cambridge and worked on an experimental thirty-line television system using a cathode ray tube (CRT) for the display. In 1936 he moved to the USA to work at Columbia Broadcasting Laboratories. There, with monochrome television based on the CRT virtually a practical proposition, he devoted his efforts to finding a way of producing colour TV images: in 1940 he gave his first demonstration of a working system. There then followed a series of experimental field-sequential colour TV systems based on segmented red, green and blue colour wheels and drums, where the problem was to find an acceptable compromise between bandwidth, resolution, colour flicker and colour-image breakup. Eventually he arrived at a system using a colour wheel in combination with a CRT containing a panchromatic phosphor screen, with a scanned raster of 405 lines and a primary colour rate of 144 fields per second. Despite the fact that the receivers were bulky, gave relatively poor, dim pictures and used standards totally incompatible with the existing 525-line, sixty fields per second interlaced monochrome (black and white) system, in 1950 the Federal Communications Commission (FCC), anxious to encourage postwar revival of the industry, authorized the system for public broadcasting. Within eighteen months, however, bowing to pressure from the remainder of the industry, which had formed its own National Television Systems Committee (NTSC) to develop a much more satisfactory, fully compatible system based on the RCA three-gun shadowmask CRT, the FCC withdrew its approval.While all this was going on, Goldmark had also been working on ideas for overcoming the poor reproduction, noise quality, short playing-time (about four minutes) and limited robustness and life of the long-established 78 rpm 12 in. (30 cm) diameter shellac gramophone record. The recent availability of a new, more robust, plastic material, vinyl, which had a lower surface noise, enabled him in 1948 to reduce the groove width some three times to 0.003 in. (0.0762 mm), use a more lightly loaded synthetic sapphire stylus and crystal transducer with improved performance, and reduce the turntable speed to 33 1/3 rpm, to give thirty minutes of high-quality music per side. This successful development soon led to the availability of stereophonic recordings, based on the ideas of Alan Blumlein at EMI in the 1930s.In 1950 Goldmark became a vice-president of CBS, but he still found time to develop a scan conversion system for relaying television pictures to Earth from the Lunar Orbiter spacecraft. He also almost brought to the market a domestic electronic video recorder (EVR) system based on the thermal distortion of plastic film by separate luminance and coded colour signals, but this was overtaken by the video cassette recorder (VCR) system, which uses magnetic tape.[br]Principal Honours and DistinctionsInstitute of Electrical and Electronics Engineers Morris N.Liebmann Award 1945.

32 Henry, Joseph
[br]b. 17 December 1797 Albany, New York, USAd. 13 May 1878 Washington, DC, USA[br]American scientist after whom the unit of inductance is named.[br]Sent to stay with relatives at the age of 6 because of the illness of his father, when the latter died in 1811 Henry was apprenticed to a silversmith and then turned to the stage. Whilst he was ill himself, a book on science fired his interest and he began studying at Albany Academy, working as a tutor to finance his studies. Initially intending to pursue medicine, he then spent some time as a surveyor before becoming Professor of Mathematics and Natural Philosophy at Albany Academy in 1826. There he became interested in the improvement of electromagnets and discovered that the use of an increased number of turns of wire round the core greatly increased their power; by 1831 he was able to supply to Yale a magnet capable of lifting almost a ton weight. During this time he also discovered the principles of magnetic induction and self-inductance. In the same year he made, but did not patent, a cable telegraph system capable of working over a distance of 1 mile (1.6 km). It was at this time, too, that he found that adiabatic expansion of gases led to their sudden cooling, thus paving the way for the development of refrigerators. For this he was recommended for, but never received, the Copley Medal of the Royal Society. Five years later he became Professor of Natural Philosophy at New Jersey College (later Princeton University), where he deduced the laws governing the operation of transformers and observed that changes in magnetic flux induced electric currents in conductors. Later he also observed that spark discharges caused electrical effects at a distance. He therefore came close to the discovery of radio waves. In 1836 he was granted a year's leave of absence and travelled to Europe, where he was able to meet Michael Faraday. It was with his help that in 1844 Samuel Morse set up the first patented electric telegraph, but, sadly, the latter seems to have reaped all the credit and financial rewards. In 1846 he became the first secretary of the Washington Smithsonian Institute and did much to develop government support for scientific research. As a result of his efforts some 500 telegraph stations across the country were equipped with meteorological equipment to supply weather information by telegraph to a central location, a facility that eventually became the US National Weather Bureau.

33 Hetzel, Max
[br]b. 5 March 1921 Basle, Switzerland[br]Swiss electrical engineer who invented the tuning-fork watch.[br]Hetzel trained as an electrical engineer at the Federal Polytechnic in Zurich and worked for several years in the field of telecommunications before joining the Bulova Watch Company in 1950. At that time several companies were developing watches with electromagnetically maintained balances, but they represented very little advance on the mechanical watch and the mechanical switching mechanism was unreliable. In 1952 Hetzel started work on a much more radical design which was influenced by a transistorized tuning-fork oscillator that he had developed when he was working on telecommunications. Tuning forks, whose vibrations were maintained electromagnetically, had been used by scientists during the nineteenth century to measure small intervals of time, but Niaudet- Breguet appears to have been the first to use a tuning fork to control a clock. In 1866 he described a mechanically operated tuning-fork clock manufactured by the firm of Breguet, but it was not successful, possibly because the fork did not compensate for changes in temperature. The tuning fork only became a precision instrument during the 1920s, when elinvar forks were maintained in vibration by thermionic valve circuits. Their primary purpose was to act as frequency standards, but they might have been developed into precision clocks had not the quartz clock made its appearance very shortly afterwards. Hetzel's design was effectively a miniaturized version of these precision devices, with a transistor replacing the thermionic valve. The fork vibrated at a frequency of 360 cycles per second, and the hands were driven mechanically from the end of one of the tines. A prototype was working by 1954, and the watch went into production in 1960. It was sold under the tradename Accutron, with a guaranteed accuracy of one minute per month: this was a considerable improvement on the performance of the mechanical watch. However, the events of the 1920s were to repeat themselves, and by the end of the decade the Accutron was eclipsed by the introduction of quartz-crystal watches.[br]Principal Honours and DistinctionsNeuchâtel Observatory Centenary Prize 1958.

34 Hosking, William
SUBJECT AREA: Civil engineering[br]b. 1800d. 1861[br]Australian architect and engineer.[br]William Hosking was appointed Professor of'the arts and construction' at King's College, London, in 1840. He was an architect and engineer who moved to England in 1819 after working as a builder in Sydney. He thus represents an unusually early example of the reverse migration of professional talent between Britain and its colonies. He exhibited drawings in London, becoming a Fellow of the Society of Antiquaries in 1830 and Fellow of the Royal Institution of British Architects in 1835. He was then caught up, like so many of his contemporaries with engineering ability, in railway building, working on the West London Railway. From 1840 to his death in 1861 he occupied the Chair at King's College, making a pioneering contribution to the development of engineering education in Britain. He published his Theory, Practice and Architecture of Bridges in 1843, and contributed to the design for the British Museum reading room.[br]Principal Honours and DistinctionsFellow of the Society of Antiquaries 1830.

35 Mavor, Henry Alexander
[br]b. 1858 Stranraer, Scotlandd. 16 July 1915 Mauchline, Ayrshire, Scotland[br]Scottish engineer who pioneered the use of electricity for lighting, power and the propulsion of ships.[br]Mavor came from a distinguished Scottish family with connections in medicine, industry and the arts. On completion of his education at Glasgow University, he joined R.J.Crompton \& Co.; then in 1883, along with William C.Muir, he established the Glasgow firm which later became well known as Mavor and Coulson. It pioneered the supply of electricity to public undertakings and equipped the first two generating stations in Scotland. Mavor and his fellow directors appreciated the potential demand by industry in Glasgow for electricity. Two industries were especially well served; first, the coal-mines, where electric lighting and power transformed efficiency and safety beyond recognition; and second, marine engineering. Here Mavor recognized the importance of the variable-speed motor in working with marine propellers which have a tighter range of efficient working speeds. In 1911 he built a 50 ft (15 m) motor launch, appropriately named Electric Arc, at Dumbarton and fitted it with an alternating-current motor driven by a petrol engine and dynamo. Within two years British shipyards were building electrically powered ships, and by the beginning of the First World War the United States Navy had a 20,000-ton collier with this new form of propulsion.[br]Principal Honours and DistinctionsVice-President, Institution of Engineers and Shipbuilders in Scotland 1894–6.BibliographyMavor published several papers on electric power supply, distribution and the use of electricity for marine purposes in the Transactions of the Institution of Engineers and Shipbuilders in Scotland between the years 1890 and 1912.Further ReadingMavor and Coulson Ltd, 1911, Electric Propulsion of Ships, Glasgow.FMW -
36 Nipkow, Paul Gottlieb
[br]b. 22 August 1860 Lauenburg, Pommern (now Lebork, Poland)d. 24 August 1940 Berlin, Germany[br]Polish electrical engineer who invented the Nipkow television scanning disc.[br]In 1884, while still a student engineer, Nipkow patented a mechanical television pick-up device using a disc with a spiral of twenty-four holes rotating at 600 rpm in front of a selenium cell. He also proposed a display on an identical synchronous disc in conjunction with a light-modulator based on the Faraday effect. Unfortunately it was not possible to realize a working system at the time because of the slow response of selenium cells and the lack of suitable electronic-sig-nal amplifiers; he was unable to pay the extension fees and so the patent lapsed. Others took up the idea, however, and in 1907 pictures were sent between London and Paris by wire. Subsequently, the principle was used by Baird, Ives, and Jenkins.For most of his working life after obtaining his doctorate, Nipkow was employed as an engineer by a company that made railway-signalling equipment, but his pioneering invention was finally recognized in 1934 when he was made Honorary President of the newly formed German Television Society.[br]Principal Honours and DistinctionsPresident, German Television Society 1934.Bibliography1884, German patent no. 30,105 (Nipkow's pioneering method of television image-scanning).Further ReadingR.W.Hubbell, 1946, 4,000 Years of Television, London: G.Harrap \& Co.KF -
37 Owen, Robert
SUBJECT AREA: Textiles[br]b. 14 May 1771 Newtown, Montgomeryshire, Walesd. 17 November 1858 Newtown, Montgomeryshire, Wales[br]Welsh cotton spinner and social reformer.[br]Robert Owen's father was also called Robert and was a saddler, ironmonger and postmaster of Newtown in Montgomeryshire. Robert, the younger, injured his digestion as a child by drinking some scalding hot "flummery", which affected him for the rest of his life. He developed a passion for reading and through this visited London when he was 10 years old. He started work as a pedlar for someone in Stamford and then went to a haberdasher's shop on old London Bridge in London. Although he found the work there too hard, he stayed in the same type of employment when he moved to Manchester.In Manchester Owen soon set up a partnership for making bonnet frames, employing forty workers, but he sold the business and bought a spinning machine. This led him in 1790 into another partnership, with James M'Connel and John Kennedy in a spinning mill, but he moved once again to become Manager of Peter Drink-water's mill. These were all involved in fine spinning, and Drinkwater employed 500 people in one of the best mills in the city. In spite of his youth, Owen claims in his autobiography (1857) that he mastered the job within six weeks and soon improved the spinning. This mill was one of the first to use Sea Island cotton from the West Indies. To have managed such an enterprise so well Owen must have had both managerial and technical ability. Through his spinning connections Owen visited Glasgow, where he met both David Dale and his daughter Anne Caroline, whom he married in 1799. It was this connection which brought him to Dale's New Lanark mills, which he persuaded Dale to sell to a Manchester consortium for £60,000. Owen took over the management of the mills on 1 January 1800. Although he had tried to carry out social reforms in the manner of working at Manchester, it was at New Lanark that Owen acquired fame for the way in which he improved both working and living conditions for the 1,500-strong workforce. He started by seeing that adequate food and groceries were available in that remote site and then built both the school and the New Institution for the Formation of Character, which opened in January 1816. To the pauper children from the Glasgow and Edinburgh slums he gave a good education, while he tried to help the rest of the workforce through activities at the Institution. The "silent monitors" hanging on the textile machines, showing the performance of their operatives, are famous, and many came to see his social experiments. Owen was soon to buy out his original partners for £84,000.Among his social reforms were his efforts to limit child labour in mills, resulting in the Factory Act of 1819. He attempted to establish an ideal community in the USA, to which he sailed in 1824. He was to return to his village of "Harmony" twice more, but broke his connection in 1828. The following year he finally withdrew from New Lanark, where some of his social reforms had been abandoned.[br]Bibliography1857, The Life of Robert Owen, Written by Himself, London.Further ReadingG.D.H.Cole, 1965, Life of Robert Owen (biography).J.Butt (ed.), 1971, Robert Owen, Prince of Cotton Spinners, Newton Abbot; S.Pollard and J.Salt (eds), 1971, Robert Owen, Prophet of the Poor.

38 Paul, Robert William
[br]b. 3 October 1869 Highbury, London, Englandd. 28 March 1943 London, England[br]English scientific instrument maker, inventor of the Unipivot electrical measuring instrument, and pioneer of cinematography.[br]Paul was educated at the City of London School and Finsbury Technical College. He worked first for a short time in the Bell Telephone Works in Antwerp, Belgium, and then in the electrical instrument shop of Elliott Brothers in the Strand until 1891, when he opened an instrument-making business at 44 Hatton Garden, London. He specialized in the design and manufacture of electrical instruments, including the Ayrton Mather galvanometer. In 1902, with a purpose-built factory, he began large batch production of his instruments. He also opened a factory in New York, where uncalibrated instruments from England were calibrated for American customers. In 1903 Paul introduced the Unipivot galvanometer, in which the coil was supported at the centre of gravity of the moving system on a single pivot. The pivotal friction was less than in a conventional instrument and could be used without accurate levelling, the sensitivity being far beyond that of any pivoted galvanometer then in existence.In 1894 Paul was asked by two entrepreneurs to make copies of Edison's kinetoscope, the pioneering peep-show moving-picture viewer, which had just arrived in London. Discovering that Edison had omitted to patent the machine in England, and observing that there was considerable demand for the machine from show-people, he began production, making six before the end of the year. Altogether, he made about sixty-six units, some of which were exported. Although Edison's machine was not patented, his films were certainly copyrighted, so Paul now needed a cinematographic camera to make new subjects for his customers. Early in 1895 he came into contact with Birt Acres, who was also working on the design of a movie camera. Acres's design was somewhat impractical, but Paul constructed a working model with which Acres filmed the Oxford and Cambridge Boat Race on 30 March, and the Derby at Epsom on 29 May. Paul was unhappy with the inefficient design, and developed a new intermittent mechanism based on the principle of the Maltese cross. Despite having signed a ten-year agreement with Paul, Acres split with him on 12 July 1895, after having unilaterally patented their original camera design on 27 May. By the early weeks of 1896, Paul had developed a projector mechanism that also used the Maltese cross and which he demonstrated at the Finsbury Technical College on 20 February 1896. His Theatrograph was intended for sale, and was shown in a number of venues in London during March, notably at the Alhambra Theatre in Leicester Square. There the renamed Animatographe was used to show, among other subjects, the Derby of 1896, which was won by the Prince of Wales's horse "Persimmon" and the film of which was shown the next day to enthusiastic crowds. The production of films turned out to be quite profitable: in the first year of the business, from March 1896, Paul made a net profit of £12,838 on a capital outlay of about £1,000. By the end of the year there were at least five shows running in London that were using Paul's projectors and screening films made by him or his staff.Paul played a major part in establishing the film business in England through his readiness to sell apparatus at a time when most of his rivals reserved their equipment for sole exploitation. He went on to become a leading producer of films, specializing in trick effects, many of which he pioneered. He was affectionately known in the trade as "Daddy Paul", truly considered to be the "father" of the British film industry. He continued to appreciate fully the possibilities of cinematography for scientific work, and in collaboration with Professor Silvanus P.Thompson films were made to illustrate various phenomena to students.Paul ended his involvement with film making in 1910 to concentrate on his instrument business; on his retirement in 1920, this was amalgamated with the Cambridge Instrument Company. In his will he left shares valued at over £100,000 to form the R.W.Paul Instrument Fund, to be administered by the Institution of Electrical Engineers, of which he had been a member since 1887. The fund was to provide instruments of an unusual nature to assist physical research.[br]Principal Honours and DistinctionsFellow of the Physical Society 1920.

39 Phillips, Horatio Frederick
SUBJECT AREA: Aerospace[br]b. 2 February 1845 London, Englandd. 15 July 1926 Hampshire, England[br]English aerodynamicist whose cambered two-surface wing sections provided the foundations for aerofoil design.[br]At the age of 19, Phillips developed an interest in flight and constructed models with lightweight engines. He spent a large amount of time and money over many years, carrying out practical research into the science of aerodynamics. In the early 1880s he built a wind tunnel with a working section of 15 in. by 10 in. (38 cm by 25 cm). Air was sucked through the working section by an adaptation of the steam injector used in boilers and invented by Henry Giffard, the airship pioneer. Phillips tested aerofoils based on the cross-section of bird's wings, with a greater curvature on the upper surface than the lower. He measured the lift and drag and showed that the major component of lift came from suction on the upper surface, rather than pressure on the lower. He took out patents for his aerofoil sections in 1884 and 1891. In addition to his wind-tunnel test, Phillips tested his wing sections on a whirling arm, as used earlier by Cayley, Wenham and Lilienthal. After a series of tests using an arm of 15 ft (4.57 m) radius, Phillips built a massive whirling arm driven by a steam engine. His test pieces were mounted on the end of the arm, which had a radius of 50 ft (15.24 m), giving them a linear speed of 70 mph (113 km/h). By 1893 Phillips was ready to put his theories to a more practical test, so he built a large model aircraft driven by a steam engine and tethered to run round a circular track. It had a wing span of 19 ft (5.79 m), but it had fifty wings, one above the other. These wings were only 10 in. (25 cm) wide and mounted in a frame, so it looked rather like a Venetian blind. At 40 mph (64 km/h) it lifted off the track. In 1904 Phillips built a full-size multi-wing aeroplane with twenty wings which just lifted off the ground but did not fly. He built another multi-wing machine in 1907, this time with four Venetian blind' frames in tandem, giving it two hundred wings! Phillips made a short flight of almost 500 ft (152 m) which could be claimed to be the first powered aeroplane flight in England by an Englishman. He retired from flying at the age of 62.[br]Bibliography1900, "Mechanical flight and matters relating thereto", Engineering (reprint).1891–3, "On the sustentation of weight by mechanical flight", Aeronautical Society of Great Britain 23rd Report.Further ReadingJ.Laurence Pritchard, 1957, "The dawn of aerodynamics", Journal of the Royal Aeronautical Society (March) (good descriptions of Phillips's early work and his wind tunnel).J.E.Hodgson, 1924, The History of Aeronautics in Great Britain, London.F.W.Brearey, 1891–3, "Remarks on experiments made by Horatio Phillips", Aeronautical Society of Great Britain 23rd Report.JDSBiographical history of technology > Phillips, Horatio Frederick

40 Preece, Sir William Henry
[br]b. 15 February 1834 Bryn Helen, Gwynedd, Walesd. 6 November 1913 Penrhos, Gwynedd, Wales[br]Welsh electrical engineer who greatly furthered the development and use of wireless telegraphy and the telephone in Britain, dominating British Post Office engineering during the last two decades of the nineteenth century.[br]After education at King's College, London, in 1852 Preece entered the office of Edwin Clark with the intention of becoming a civil engineer, but graduate studies at the Royal Institution under Faraday fired his enthusiasm for things electrical. His earliest work, as connected with telegraphy and in particular its application for securing the safe working of railways; in 1853 he obtained an appointment with the Electric and National Telegraph Company. In 1856 he became Superintendent of that company's southern district, but four years later he moved to telegraph work with the London and South West Railway. From 1858 to 1862 he was also Engineer to the Channel Islands Telegraph Company. When the various telegraph companies in Britain were transferred to the State in 1870, Preece became a Divisional Engineer in the General Post Office (GPO). Promotion followed in 1877, when he was appointed Chief Electrician to the Post Office. One of the first specimens of Bell's telephone was brought to England by Preece and exhibited at the British Association meeting in 1877. From 1892 to 1899 he served as Engineer-in-Chief to the Post Office. During this time he made a number of important contributions to telegraphy, including the use of water as part of telegraph circuits across the Solent (1882) and the Bristol Channel (1888). He also discovered the existence of inductive effects between parallel wires, and with Fleming showed that a current (thermionic) flowed between the hot filament and a cold conductor in an incandescent lamp.Preece was distinguished by his administrative ability, some scientific insight, considerable engineering intuition and immense energy. He held erroneous views about telephone transmission and, not accepting the work of Oliver Heaviside, made many errors when planning trunk circuits. Prior to the successful use of Hertzian waves for wireless communication Preece carried out experiments, often on a large scale, in attempts at wireless communication by inductive methods. These became of historic interest only when the work of Maxwell and Hertz was developed by Guglielmo Marconi. It is to Preece that credit should be given for encouraging Marconi in 1896 and collaborating with him in his early experimental work on radio telegraphy.While still employed by the Post Office, Preece contributed to the development of numerous early public electricity schemes, acting as Consultant and often supervising their construction. At Worcester he was responsible for Britain's largest nineteenth-century public hydro-electric station. He received a knighthood on his retirement in 1899, after which he continued his consulting practice in association with his two sons and Major Philip Cardew. Preece contributed some 136 papers and printed lectures to scientific journals, ninety-nine during the period 1877 to 1894.[br]Principal Honours and DistinctionsCB 1894. Knighted (KCB) 1899.
