61 Mond, Ludwig
SUBJECT AREA: Chemical technology[br]b. 7 March 1839 Cassel, Germanyd. 11 December 1909 London, England[br]German (naturalized English) industrial chemist.[br]Born into a prosperous Jewish merchant family, Mond studied at the Polytechnic in Cassel and then under the distinguished chemists Hermann Kolbe at Marburg and Bunsen at Heidelberg from 1856. In 1859 he began work as an industrial chemist in various works in Germany and Holland. At this time, Mond was pursuing his method for recovering sulphur from the alkali wastes in the Leblanc soda-making process. Mond came to England in 1862 and five years later settled permanently, in partnership with John Hutchinson \& Co. at Widnes, to perfect his process, although complete success eluded him. He became a naturalized British subject in 1880.In 1872 Mond became acquainted with Ernest Solvay, the Belgian chemist who developed the ammonia-soda process which finally supplanted the Leblanc process. Mond negotiated the English patent rights and set up the first ammoniasoda plant in England at Winnington in Cheshire, in partnership with John Brunner. After overcoming many difficulties by incessant hard work, the process became a financial success and in 1881 Brunner, Mond \& Co. was formed, for a time the largest alkali works in the world. In 1926 the company merged with others to form Imperial Chemical Industries Ltd (ICI). The firm was one of the first to adopt the eight-hour day and to provide model dwellings and playing fields for its employees.From 1879 Mond took up the production of ammonia and this led to the Mond producer-gas plant, patented in 1883. The process consisted of passing air and steam over coal and coke at a carefully regulated temperature. Ammonia was generated and, at the same time, so was a cheap and useful producer gas. Mond's major discovery followed the observation in 1889 that carbon monoxide could combine with nickel in its ore at around 60°C to form a gaseous compound, nickel carbonyl. This, on heating to a higher temperature, would then decompose to give pure nickel. Mond followed up this unusual way of producing and purifying a metal and by 1892 had succeeded in setting up a pilot plant to perfect a large-scale process and went on to form the Mond Nickel Company.Apart from being a successful industrialist, Mond was prominent in scientific circles and played a leading role in the setting up of the Society of Chemical Industry in 1881. The success of his operations earned him great wealth, much of which he donated for learned and charitable purposes. He formed a notable collection of pictures which he bequeathed to the National Gallery.[br]Principal Honours and DistinctionsFRS 1891.Bibliography1885, "On the origin of the ammonia-soda process", Journal of the Society of Chemical Industry 4:527–9.1895.

62 Wenham, Francis Herbert
SUBJECT AREA: Aerospace[br]b. 1824 London, Englandd. 11 August 1908 Folkestone, England[br]English engineer, inventor and pioneer aerodynamicist who built the first wind tunnel.[br]Wenham trained as a marine engineer and later specialized in screw propellers and high-pressure engines. He had many interests. He took his steamboat to the Nile and assisted the photographer F.Frith to photograph Egyptian tombs by devising a series of mirrors to deflect sunlight into the dark recesses. He experimented with gas engines and produced a hot-air engine. Wenham was a leading, if controversial, figure in the Microscopical Society and a member of the Royal Photographic Society; he developed an enlarger.Wenham was interested in both mechanical and lighter-than-air flight. One of his friends was James Glaisher, a well-known balloonist who made many ascents to gather scientific information. When the (Royal) Aeronautical Society of Great Britain was founded in 1866, the Rules were drawn up by Wenham, Glaisher and the Honorary Secretary, F.W.Brearey. At the first meeting of the Society, on 27 June 1866, "On aerial locomotion and the laws by which heavy bodies impelled through the air are sustained" was read by Wenham. In his paper Wenham described his experiments with a whirling arm (used earlier by Cayley) to measure lift and drag on flat surfaces inclined at various angles of incidence. His studies of birds' wings and, in particular, their wing loading, showed that they derived most of their lift from the front portion, hence a long, thin wing was better than a short, wide one. He published illustrations of his glider designs covering his experiments of c. 1858–9. One of these had five slender wings one above the other, an idea later developed by Horatio Phillips. Wenham had some success with a model, but no real success with his full-size gliders.In 1871, Wenham and John Browning constructed the first wind tunnel designed for aeronautical research. It utilized a fan driven by a steam engine to propel the air and had a working section of 18 in. (116 cm). Wenham continued to play an important role in aeronautical matters for many years, including a lengthy exchange of ideas with Octave Chanute from 1892 onwards.[br]Principal Honours and DistinctionsHonorary Member of the (Royal) Aeronautical Society.BibliographyWenham published many reports and papers. These are listed, together with a reprint of his paper "Aerial locomotion", in the Journal of the Royal Aeronautical Society (August 1958).Further ReadingTwo papers by J.Laurence Pritchard, 1957, "The dawn of aerodynamics" Journal of the Royal Aeronautical Society (March); 1958, "Francis Herbert Wenham", Journal of the Royal Aeronautical Society (August) (both papers describe Wenham and his work).J.E.Hodgson, 1924, History of Aeronautics in Great Britain, London.JDSBiographical history of technology > Wenham, Francis Herbert

66 Appleton, Sir Edward Victor
[br]b. 6 September 1892 Bradford, Englandd. 21 April 1965 Edinburgh, Scotland[br]English physicist awarded the Nobel Prize for Physics for his discovery of the ionospheric layer, named after him, which is an efficient reflector of short radio waves, thereby making possible long-distance radio communication.[br]After early ambitions to become a professional cricketer, Appleton went to St John's College, Cambridge, where he studied under J.J.Thompson and Ernest Rutherford. His academic career interrupted by the First World War, he served as a captain in the Royal Engineers, carrying out investigations into the propagation and fading of radio signals. After the war he joined the Cavendish Laboratory, Cambridge, as a demonstrator in 1920, and in 1924 he moved to King's College, London, as Wheatstone Professor of Physics.In the following decade he contributed to developments in valve oscillators (in particular, the "squegging" oscillator, which formed the basis of the first hard-valve time-base) and gained international recognition for research into electromagnetic-wave propagation. His most important contribution was to confirm the existence of a conducting ionospheric layer in the upper atmosphere capable of reflecting radio waves, which had been predicted almost simultaneously by Heaviside and Kennelly in 1902. This he did by persuading the BBC in 1924 to vary the frequency of their Bournemouth transmitter, and he then measured the signal received at Cambridge. By comparing the direct and reflected rays and the daily variation he was able to deduce that the Kennelly- Heaviside (the so-called E-layer) was at a height of about 60 miles (97 km) above the earth and that there was a further layer (the Appleton or F-layer) at about 150 miles (240 km), the latter being an efficient reflector of the shorter radio waves that penetrated the lower layers. During the period 1927–32 and aided by Hartree, he established a magneto-ionic theory to explain the existence of the ionosphere. He was instrumental in obtaining agreement for international co-operation for ionospheric and other measurements in the form of the Second Polar Year (1932–3) and, much later, the International Geophysical Year (1957–8). For all this work, which made it possible to forecast the optimum frequencies for long-distance short-wave communication as a function of the location of transmitter and receiver and of the time of day and year, in 1947 he was awarded the Nobel Prize for Physics.He returned to Cambridge as Jacksonian Professor of Natural Philosophy in 1939, and with M.F. Barnett he investigated the possible use of radio waves for radio-location of aircraft. In 1939 he became Secretary of the Government Department of Scientific and Industrial Research, a post he held for ten years. During the Second World War he contributed to the development of both radar and the atomic bomb, and subsequently served on government committees concerned with the use of atomic energy (which led to the establishment of Harwell) and with scientific staff.[br]Principal Honours and DistinctionsKnighted (KCB 1941, GBE 1946).

[br]b. 18 October 1863 Kimmerghame, Berwickshire, Scotlandd. 19 February 1930 London, England[br]Scottish electrical engineer who correctly predicted the development of electronic television.[br]After a time at Cargilfield Trinity School, Campbell-Swinton went to Fettes College in Edinburgh from 1878 to 1881 and then spent a year abroad in France. From 1882 until 1887 he was employed at Sir W.G.Armstrong's works in Elswick, Newcastle, following which he set up his own electrical contracting business in London. This he gave up in 1904 to become a consultant. Subsequently he was an engineer with many industrial companies, including the W.T.Henley Telegraph Works Company, Parson Marine Steam Turbine Company and Crompton Parkinson Ltd, of which he became a director. During this time he was involved in electrical and scientific research, being particularly associated with the development of the Parson turbine.In 1903 he tried to realize distant electric vision by using a Braun oscilloscope tube for the. image display, a second tube being modified to form a synchronously scanned camera, by replacing the fluorescent display screen with a photoconductive target. Although this first attempt at what was, in fact, a vidicon camera proved unsuccessful, he was clearly on the right lines and in 1908 he wrote a letter to Nature with a fairly accurate description of the principles of an all-electronic television system using magnetically deflected cathode ray tubes at the camera and receiver, with the camera target consisting of a mosaic of photoconductive elements that were scanned and discharged line by line by an electron beam. He expanded on his ideas in a lecture to the Roentgen Society, London, in 1911, but it was over twenty years before the required technology had advanced sufficiently for Shoenberg's team at EMI to produce a working system.[br]Principal Honours and DistinctionsFRS (Member of Council 1927 and 1929).

68 Dancer, John Benjamin
SUBJECT AREA: Photography, film and optics[br]b. 1812 Englandd. 1887 England[br]English instrument maker and photographer, pioneer of microphotography.[br]The son of a scientific instrument maker, Dancer was educated privately in Liverpool, where from 1817 his father practised his trade. John Benjamin became a skilled instrument maker in his own right, assisting in the family business until his father's death in 1835. He set up on his own in Liverpool in 1840 and in Manchester in 1841. In the course of his career Dancer made instruments for several of the leading scientists of the day, his clients including Brewster, Dalton and Joule.Dancer became interested in photography as soon as the new art was announced in 1839 and practised the processes of both Talbot and Daguerre. It was later claimed that as early as 1839 he used an achromatic lens combination to produce a minute image on a daguerreotype plate, arguably the world's first microphotograph and the precursor of modern microfilm. It was not until the introduction of Archer's wet-collodion process in 1851 that Dancer was able to perfect the technique however. He went on to market a long series of microphotographs which proved extremely popular with both the public and contemporary photographers. It was examples of Dancer's microphotographs that prompted the French photographer Dagron to begin his work in the same field. In 1853 Dancer constructed a binocular stereoscopic camera, the first practicable instrument of its type. In an improved form it was patented and marketed in 1856.Dancer also made important contributions to the magic lantern. He was the first to suggest the use of limelight as an illuminant, pioneered the use of photographic lantern slides and devised an ingenious means of switching gas from one lantern illuminant to another to produce what were known as dissolving views.

SUBJECT AREA: Electricity[br]b. 12 March 1790 London, Englandd. 13 March 1845 London, England[br]English chemist, inventor of the Daniell primary electric cell.[br]With an early bias towards science, Daniell's interest in chemistry was formed when he joined a relative's sugar-refining business. He formed a lifelong friendship with W.T.Brande, Professor of Chemistry at the Royal Institution, and together they revived the journal of the Royal Institution, to which Daniell submitted many of his early papers on chemical subjects. He made many contributions to the science of meteorology and in 1820 invented a hydrometer, which became widely used and gave precision to the measurement of atmospheric moisture. As one of the originators of the Society for Promoting Useful Knowledge, Daniell edited several of its early publications. His work on crystallization established his reputation as a chemist and in 1831 he was appointed the first Professor of Chemistry at King's College, London, where he was largely responsible for establishing its department of applied science. He was also involved in the Chemical Society of London and served as its Vice-President. At King's College he began the research into current electricity with which his name is particularly associated. His investigations into the zinc-copper cell revealed that the rapid decline in power was due to hydrogen gas being liberated at the positive electrode. Daniell's cell, invented in 1836, employed a zinc electrode in dilute sulphuric acid and a copper electrode in a solution of copper sulphate, the electrodes being separated by a porous membrane, typically an unglazed earthenware pot. He was awarded the Copley Medal of the Royal Society for his invention which avoided the "polarization" of the simple cell and provided a further source of current for electrical research and for commercial applications such as electroplating. Although the high internal resistance of the Daniell cell limited the current and the potential was only 1.1 volts, the voltage was so unchanging that it was used as a reference standard until the 1870s, when J. Lattimer Clark devised an even more stable cell.[br]Principal Honours and DistinctionsFRS 1814.

70 Grove, Sir William Robert
SUBJECT AREA: Electricity[br]b. 11 July 1811 Swansea, Walesd. 1 August 1896 London, England[br]Welsh chemist and physicist, inventor of the Grove electrochemical primary cell.[br]After education at Brasenose College, Oxford, Grove was called to the Bar in 1835. Instead of immediately practising, he became involved in electrical research, devising in 1839 the cell that bears his name. He became Professor of Experimental Philosophy at the London Institution from 1840 to 1845; it was during this period that he built up his high reputation among physicists. In 1846 he published On the Correlation of Physical Forces, which was based on a course of his lectures. He returned to the practice of law, becoming a judge in 1871, but retained his interest in scientific research during his sixteen-year occupancy of the Bench. He served as a member of the Council of the Royal Society in 1846 and 1847 and played a leading part in its reform. Contributing to the science of electrochemistry, he invented the Grove cell, which together with its modification by Bunsen became an important source of electrical energy during the middle of the nineteenth century, before mechanically driven generators became available. The Grove cell had a platinum electrode immersed in strong nitric acid, separated by a porous diaphragm from a zinc electrode in weak sulphuric acid. The hydrogen formed at the platinum electrode was immediately oxidized by the acid, turning it into water. This avoided the polarization which occurred in the early copper-zinc cells. It was a very powerful primary cell with a high voltage and a low internal resistance, but it produced objectionable fumes. Grove also invented his "gas battery", the earliest fuel cell, in which a current resulted from the chemical energy released from combining oxygen and hydrogen. This was developed by Rawcliffe and others, and found applications as a power source in manned spacecraft.[br]Principal Honours and DistinctionsKnighted 1872. FRS 1840.

71 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. From 1852 he was a member of the Lighthouse Board, contributing to improvements in lighting and sound warning systems and becoming its chairman in 1871. During the Civil War he was a technical advisor to President Lincoln. He was a founder of the National Academy of Science and served as its President for eleven years.[br]Principal Honours and DistinctionsPresident, American Association for the Advancement of Science 1849.

72 Huygens, Christiaan
SUBJECT AREA: Horology[br]b. 14 April 1629 The Hague, the Netherlandsd. 8 June 1695 The Hague, the Netherlands[br]Dutch scientist who was responsible for two of the greatest advances in horology: the successful application of both the pendulum to the clock and the balance spring to the watch.[br]Huygens was born into a cultured and privileged class. His father, Constantijn, was a poet and statesman who had wide interests. Constantijn exerted a strong influence on his son, who was educated at home until he reached the age of 16. Christiaan studied law and mathematics at Ley den University from 1645 to 1647, and continued his studies at the Collegium Arausiacum in Breda until 1649. He then lived at The Hague, where he had the means to devote his time entirely to study. In 1666 he became a Member of the Académie des Sciences in Paris and settled there until his return to The Hague in 1681. He also had a close relationship with the Royal Society and visited London on three occasions, meeting Newton on his last visit in 1689. Huygens had a wide range of interests and made significant contributions in mathematics, astronomy, optics and mechanics. He also made technical advances in optical instruments and horology.Despite the efforts of Burgi there had been no significant improvement in the performance of ordinary clocks and watches from their inception to Huygens's time, as they were controlled by foliots or balances which had no natural period of oscillation. The pendulum appeared to offer a means of improvement as it had a natural period of oscillation that was almost independent of amplitude. Galileo Galilei had already pioneered the use of a freely suspended pendulum for timing events, but it was by no means obvious how it could be kept swinging and used to control a clock. Towards the end of his life Galileo described such a. mechanism to his son Vincenzio, who constructed a model after his father's death, although it was not completed when he himself died in 1642. This model appears to have been copied in Italy, but it had little influence on horology, partly because of the circumstances in which it was produced and possibly also because it differed radically from clocks of that period. The crucial event occurred on Christmas Day 1656 when Huygens, quite independently, succeeded in adapting an existing spring-driven table clock so that it was not only controlled by a pendulum but also kept it swinging. In the following year he was granted a privilege or patent for this clock, and several were made by the clockmaker Salomon Coster of The Hague. The use of the pendulum produced a dramatic improvement in timekeeping, reducing the daily error from minutes to seconds, but Huygens was aware that the pendulum was not truly isochronous. This error was magnified by the use of the existing verge escapement, which made the pendulum swing through a large arc. He overcame this defect very elegantly by fitting cheeks at the pendulum suspension point, progressively reducing the effective length of the pendulum as the amplitude increased. Initially the cheeks were shaped empirically, but he was later able to show that they should have a cycloidal shape. The cheeks were not adopted universally because they introduced other defects, and the problem was eventually solved more prosaically by way of new escapements which reduced the swing of the pendulum. Huygens's clocks had another innovatory feature: maintaining power, which kept the clock going while it was being wound.Pendulums could not be used for portable timepieces, which continued to use balances despite their deficiencies. Robert Hooke was probably the first to apply a spring to the balance, but his efforts were not successful. From his work on the pendulum Huygens was well aware of the conditions necessary for isochronism in a vibrating system, and in January 1675, with a flash of inspiration, he realized that this could be achieved by controlling the oscillations of the balance with a spiral spring, an arrangement that is still used in mechanical watches. The first model was made for Huygens in Paris by the clockmaker Isaac Thuret, who attempted to appropriate the invention and patent it himself. Huygens had for many years been trying unsuccessfully to adapt the pendulum clock for use at sea (in order to determine longitude), and he hoped that a balance-spring timekeeper might be better suited for this purpose. However, he was disillusioned as its timekeeping proved to be much more susceptible to changes in temperature than that of the pendulum clock.[br]Principal Honours and DistinctionsFRS 1663.

73 Jablochkoff, Paul
[br]b. 14 September 1847 Serdobsk, Russiad. April 1894 St Petersburg, Russia[br]Russian military engineer and inventor of an electric "candle", the invention of which gave an immense impetus to electric lighting in the 1870s.[br]Jablochkoff studied at the Military Engineering College in St Petersburg. Having a scientific bent, he was sent to the Military Galvano Technical School. At the end of his military service in 1871 he was appointed Director General of the Moscow-Kursk telegraph lines for the Midi Railway Company. At this time he began to develop an interest in electric lighting, and in 1875 he left the Imperial Telegraph Service to devote his time exclusively to scientific pursuits. He found employment at the workshop of M Bréguet in Paris, where Gramme dynamos and Serrin arc lamps were being constructed. After some experimentation he found a means of producing a carbon arc that regulated itself without any mechanism. This lamp, the Jablochkoff candle, with two carbon rods placed parallel to each other and so close that an arc formed at the ends, could continue to burn until the rods were consumed. Plaster of Paris was used to separate the two electrodes and crumbled away as the carbon burned, thus exposing fresh carbon. These lamps were used in May 1878 in Paris to illuminate the avenue de l'Opéra, and later in Rome and London, and in essence were the first practical electric street lighting. Since there was no regulating mechanism, several candles could be placed in a single circuit. Despite inherent defects, such as the inability to restart the lamps after they were extinguished by wind or interruption of supply, they remained in use for some purposes for several years on account of their simplicity and cheapness. In 1877 Jablochkoff obtained the earliest patent to employ transformers to distribute current in an alternating-current circuit.[br]Bibliography11 September 1876, British patent no. 3,552 (Jablochkoff's candle).22 May 1877, British patent no. 1,996 (transformer or induction coil distribution).Further ReadingW.J.King, 1962, The Development of Electrical Technology in the 19th Century, Washington, DC: Smithsonian Institution, Paper 30, pp. 393–407 (a detailed account).

74 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.

[br]b. 13 April 1892 Brechin, Angus, Scotlandd. 6 December 1973 Inverness, Scotland[br]Scottish engineer and scientific adviser known for his work on radar.[br]Following education at Brechin High School, Watson-Watt entered University College, Dundee (then a part of the University of St Andrews), obtaining a BSc in engineering in 1912. From 1912 until 1921 he was Assistant to the Professor of Natural Philosophy at St Andrews, but during the First World War he also held various posts in the Meteorological Office. During. this time, in 1916 he proposed the use of cathode ray oscillographs for radio-direction-finding displays. He joined the newly formed Radio Research Station at Slough when it was opened in 1924, and 3 years later, when it amalgamated with the Radio Section of the National Physical Laboratory, he became Superintendent at Slough. At this time he proposed the name "ionosphere" for the ionized layer in the upper atmosphere. With E.V. Appleton and J.F.Herd he developed the "squegger" hard-valve transformer-coupled timebase and with the latter devised a direction-finding radio-goniometer.In 1933 he was asked to investigate possible aircraft counter-measures. He soon showed that it was impossible to make the wished-for radio "death-ray", but had the idea of using the detection of reflected radio-waves as a means of monitoring the approach of enemy aircraft. With six assistants he developed this idea and constructed an experimental system of radar (RAdio Detection And Ranging) in which arrays of aerials were used to detect the reflected signals and deduce the bearing and height. To realize a practical system, in September 1936 he was appointed Director of the Bawdsey Research Station near Felixstowe and carried out operational studies of radar. The result was that within two years the East Coast of the British Isles was equipped with a network of radar transmitters and receivers working in the 7–14 metre band—the so-called "chain-home" system—which did so much to assist the efficient deployment of RAF Fighter Command against German bombing raids on Britain in the early years of the Second World War.In 1938 he moved to the Air Ministry as Director of Communications Development, becoming Scientific Adviser to the Air Ministry and Ministry of Aircraft Production in 1940, then Deputy Chairman of the War Cabinet Radio Board in 1943. After the war he set up Sir Robert Watson-Watt \& Partners, an industrial consultant firm. He then spent some years in relative retirement in Canada, but returned to Scotland before his death.[br]Principal Honours and DistinctionsKnighted 1942. CBE 1941. FRS 1941. US Medal of Merit 1946.

76 Wilde, Henry
SUBJECT AREA: Electricity[br]b. 1833 Manchester, Englandd. 28 March 1919 Alderley Edge, Cheshire, England[br]English inventor and pioneer manufacturer of electrical generators.[br]After completing a mechanical engineering apprenticeship Wilde commenced in business as a telegraph and lightning conductor specialist in Lancashire. Several years spent on the design of an alphabetic telegraph resulted in a number of patents. In 1864 he secured a patent for an electromagnetic generator which gave alternating current from a shuttle-wound armature, the field being excited by a small direct-current magneto. Wilde's invention was described to the Royal Society by Faraday in March 1866. When demonstrated at the Paris Exhibition of 1867, Wilde's machine produced sufficient power to maintain an arc light. The small size of the generator provided a contrast to the large and heavy magnetoelectric machines also exhibited. He discovered, by experiment, that alternators in synchronism could be connected in parallel. At about the same time John Hopkinson arrived at the same conclusions on theoretical grounds.Between 1866 and 1877 he sold ninety-four machines with commutators for electroplating purposes, a number being purchased by Elkingtons of Birmingham. He also supplied generators for the first use of electric searchlights on battleships. In his early experiments Wilde was extremely close to the discovery of true self-excitation from remnant magnetism, a principle which he was to discover in 1867 on machines intended for electroplating. His patents proved to be financially successful and he retired from business in 1884. During the remaining thirty-five years of his life he published many scientific papers, turning from experimental work to philosophical and, finally, theological matters. His record as an inventor established him as a pioneer of electrical engineering, but his lack of scientific training was to restrict his later contributions.[br]Principal Honours and DistinctionsFRS 1886.Bibliography1 December 1863, British patent no. 3,006 (alternator with a magneto-exciter).1866, Proceedings of the Royal Society 14:107–11 (first report on Wilde's experiments). 1900, autobiographical note, Journal of the Institution of Electrical Engineers 29:3–17.Further ReadingW.W.Haldane Gee. 1920, biography, Memoirs, Manchester Literary and Philosophical Society 63:1–16 (a comprehensive account).P.Dunsheath, 1962, A History of Electrical Engineering, London: Faber \& Faber, pp. 110–12 (a short account).GW -
