1 Ayrton, William Edward
[br]b. 14 September 1847 London, Englandd. 8 November 1908 London, England[br]English physicist, inventor and pioneer in technical education.[br]After graduating from University College, London, Ayrton became for a short time a pupil of Sir William Thomson in Glasgow. For five years he was employed in the Indian Telegraph Service, eventually as Superintendent, where he assisted in revolutionizing the system, devising methods of fault detection and elimination. In 1873 he was invited by the Japanese Government to assist as Professor of Physics and Telegraphy in founding the Imperial College of Engineering in Tokyo. There he created a teaching laboratory that served as a model for those he was later to organize in England and which were copied elsewhere. It was in Tokyo that his joint researches with Professor John Perry began, an association that continued after their return to England. In 1879 he became Professor of Technical Physics at the City and Guilds Institute in Finsbury, London, and later was appointed Professor of Physics at the Central Institution in South Kensington.The inventions of Avrton and Perrv included an electric tricycle in 1882, the first practicable portable ammeter and other electrical measuring instruments. By 1890, when the research partnership ended, they had published nearly seventy papers in their joint names, the emphasis being on a mathematical treatment of subjects including electric motor design, construction of electrical measuring instruments, thermodynamics and the economical use of electric conductors. Ayrton was then employed as a consulting engineer by government departments and acted as an expert witness in many important patent cases.[br]Principal Honours and DistinctionsFRS 1881.

2 Jacobi, Moritz Hermann von
SUBJECT AREA: Electricity[br]b. 21 September 1801 Potsdam, Germanyd. 27 February 1874 St Petersburg, Russia[br]German scientist who developed one of the first practical electric motors.[br]After studying architecture at Göttingen University, Jacobi turned his attention to physics and chemistry. In 1835 he was appointed a professor of civil engineering at the University of Dorpat (which later assumed the Estonian name of Tartu). Later, moving to St Petersburg, he became a member of the Imperial Academy of Sciences and commenced research on electricity and its practical applications. In December 1834 Jacobi presented a paper to the Academy of Sciences in Paris in which he stated that he had obtained rotation by electromagnetic methods in May of that year. Tsar Nicholas of Russia gave him a grant to prove that his electric motor had a practical application. Jacobi had a boat constructed that measured 28 ft in length and was propelled by paddles connected to an electric motor of his own design. Powered by Grove cells, it carried about fourteen passengers at a speed of almost 3 mph (5 km/h) on the River Neva. The weight of and possibly the fumes from the batteries contributed to the abandonment of the project. In 1839 Jacobi introduced electrotyping, i.e. the reproduction of forms by electrodeposition, which was one of the first commercial applications of electricity. In 1840 he reported the results of his investigations into the power of the electromagnet as a function of various parameters to the British Association.[br]Principal Honours and DistinctionsMember, Imperial Academy of Sciences, St Petersburg, 1847.BibliographyJacobi's papers are listed in Catalogue of Scientific Papers, 1868, Vol. III, London: Royal Society, pp. 517–18.1837, Annals of Electricity 1:408–15 and 419–44 (describes his motor).Further ReadingBiography, 1876, Bulletin de l'Académie imperiale des sciences de St Petersburg 21:262–79.E.H.Huntress, 1951, in Proceedings of the American Academy of Arts and Sciences 79: 22–3 (a short biography).B.Bowers, 1982, A History of Electric Light and Power, London.GWBiographical history of technology > Jacobi, Moritz Hermann von

4 Sturgeon, William
SUBJECT AREA: Electricity[br]b. 22 May 1783 Whittington, Lancashire, Englandd. 4 December 1850 Prestwich, Manchester, England[br]English inventor and lecturer, discoverer of the electromagnet, and inventor of the first electric motor put to practical use.[br]After leaving an apprenticeship as a shoemaker, Sturgeon enlisted in the militia. Self-educated during service as a private in the Royal Artillery, he began to construct scientific apparatus. When he left the army in 1820 Sturgeon became an industrious writer, contributing papers to the Philosophical Magazine. In 1823 he was appointed Lecturer in Natural Science at the East India Company's Military College in Addiscombe. His invention in 1823 of an electromagnet with a horseshoe-shaped, soft iron core provided a much more concentrated magnetic field than previously obtained. An electric motor he designed in 1832 embodied his invention of the first metallic commutator. This was used to rotate a meat-roasting jack. Over an extended period he conducted researches into atmospheric electricity and also introduced the practice of amalgamating zinc in primary cells to prevent local action.Sturgeon became Lecturer at the Adelaide Gallery, London, in 1832, an appointment of short duration, terminating when the gallery closed. In 1836 he established a monthly publication, The Annals of Electricity, Magnetism and Chemistry; and Guardian of Experimental Science, the first journal in England to be devoted to the subject. It was to this journal that James Prescot Joule contributed the results of his own researches in electromagnetism. Due to lack of financial support the publication ceased in 1843 after ten volumes had been issued. At the age of 57 Sturgeon became Superintendent of the Victoria Gallery of Practical Science in Manchester; after this gallery closed, the last five years of his life were spent in considerable poverty.[br]Principal Honours and DistinctionsSociety of Arts Silver Medal 1825.Bibliography1836, Annals of Electricity 1:75–8 (describes his motor).All his published papers were collected in Scientific Researches, Experimental and Theoretical in Electricity, Magnetism and Electro-Chemistry, 1850, Bury; 1852, London.Further ReadingJ.P.Joule, 1857, biography, in Memoirs of the Literary and Philosophical Society 14, Manchester: 53–8.Biography, 1895, Electrician 35:632–5 (includes a list of Sturgeon's published work).

6 Gramme, Zénobe Théophile
[br]b. 4 April 1826 Jehay-Bodignée, Belgiumd. 20 January 1901 Bois de Colombes, Paris, France[br]Belgian engineer whose improvements to the dynamo produced a machine ready for successful commercial exploitation.[br]Gramme trained as a carpenter and showed an early talent for working with machinery. Moving to Paris he found employment in the Alliance factory as a model maker. With a growing interest in electricity he left to become an instrument maker with Heinrich Daniel Rühmkorff. In 1870 he patented the uniformly wound ring-armature dynamo with which his name is associated. Together with Hippolyte Fontaine, in 1871 Gramme opened a factory to manufacture his dynamos. They rapidly became a commercial success for both arc lighting and electrochemical purposes, international publicity being achieved at exhibitions in Vienna, Paris and Philadelphia. It was the realization that a Gramme machine was capable of running as a motor, i.e. the reversibility of function, that illustrated the entire concept of power transmission by electricity. This was first publicly demonstrated in 1873. In 1874 Gramme reduced the size and increased the efficiency of his generators by relying completely on the principle of self-excitation. It was the first practical machine in which were combined the features of continuity of commutation, self-excitation, good lamination of the armature core and a reasonably good magnetic circuit. This dynamo, together with the self-regulating arc lamps then available, made possible the innumerable electric-lighting schemes that followed. These were of the greatest importance in demonstrating that electric lighting was a practical and economic means of illumination. Gramme also designed an alternator to operate Jablochkoff candles. For some years he took an active part in the operations of the Société Gramme and also experimented in his own workshop without collaboration, but made no further contribution to electrical technology.[br]Principal Honours and DistinctionsKnight Commander, Order of Leopold of Belgium 1897.

7 Ferranti, Sebastian Ziani de
[br]b. 9 April 1864 Liverpool, Englandd. 13 January 1930 Zurich, Switzerland[br]English manufacturing engineer and inventor, a pioneer and early advocate of high-voltage alternating-current electric-power systems.[br]Ferranti, who had taken an interest in electrical and mechanical devices from an early age, was educated at St Augustine's College in Ramsgate and for a short time attended evening classes at University College, London. Rather than pursue an academic career, Ferranti, who had intense practical interests, found employment in 1881 with the Siemens Company (see Werner von Siemens) in their experimental department. There he had the opportunity to superintend the installation of electric-lighting plants in various parts of the country. Becoming acquainted with Alfred Thomson, an engineer, Ferranti entered into a short-lived partnership with him to manufacture the Ferranti alternator. This generator, with a unique zig-zag armature, had an efficiency exceeding that of all its rivals. Finding that Sir William Thomson had invented a similar machine, Ferranti formed a company with him to combine the inventions and produce the Ferranti- Thomson machine. For this the Hammond Electric Light and Power Company obtained the sole selling rights.In 1885 the Grosvenor Gallery Electricity Supply Corporation was having serious problems with its Gaulard and Gibbs series distribution system. Ferranti, when consulted, reviewed the design and recommended transformers connected across constant-potential mains. In the following year, at the age of 22, he was appointed Engineer to the company and introduced the pattern of electricity supply that was eventually adopted universally. Ambitious plans by Ferranti for London envisaged the location of a generating station of unprecedented size at Deptford, about eight miles (13 km) from the city, a departure from the previous practice of placing stations within the area to be supplied. For this venture the London Electricity Supply Corporation was formed. Ferranti's bold decision to bring the supply from Deptford at the hitherto unheard-of pressure of 10,000 volts required him to design suitable cables, transformers and generators. Ferranti planned generators with 10,000 hp (7,460 kW)engines, but these were abandoned at an advanced stage of construction. Financial difficulties were caused in part when a Board of Trade enquiry in 1889 reduced the area that the company was able to supply. In spite of this adverse situation the enterprise continued on a reduced scale. Leaving the London Electricity Supply Corporation in 1892, Ferranti again started his own business, manufacturing electrical plant. He conceived the use of wax-impregnated paper-insulated cables for high voltages, which formed a landmark in the history of cable development. This method of flexible-cable manufacture was used almost exclusively until synthetic materials became available. In 1892 Ferranti obtained a patent which set out the advantages to be gained by adopting sector-shaped conductors in multi-core cables. This was to be fundamental to the future design and development of such cables.A total of 176 patents were taken out by S.Z. de Ferranti. His varied and numerous inventions included a successful mercury-motor energy meter and improvements to textile-yarn produc-tion. A transmission-line phenomenon where the open-circuit voltage at the receiving end of a long line is greater than the sending voltage was named the Ferranti Effect after him.[br]Principal Honours and DistinctionsFRS 1927.

8 Westinghouse, George
[br]b. 6 October 1846 Central Bridge, New York, USAd. 12 March 1914 New York, New York, USA[br]American inventor and entrepreneur, pioneer of air brakes for railways and alternating-current distribution of electricity.[br]George Westinghouse's father was an ingenious manufacturer of agricultural implements; the son, after a spell in the Union Army during the Civil War, and subsequently in the Navy as an engineer, went to work for his father. He invented a rotary steam engine, which proved impracticable; a rerailing device for railway rolling stock in 1865; and a cast-steel frog for railway points, with longer life than the cast-iron frogs then used, in 1868–9. During the same period Westinghouse, like many other inventors, was considering how best to meet the evident need for a continuous brake for trains, i.e. one by which the driver could apply the brakes on all vehicles in a train simultaneously instead of relying on brakesmen on individual vehicles. By chance he encountered a magazine article about the construction of the Mont Cenis Tunnel, with a description of the pneumatic tools invented for it, and from this it occurred to him that compressed air might be used to operate the brakes along a train.The first prototype was ready in 1869 and the Westinghouse Air Brake Company was set up to manufacture it. However, despite impressive demonstration of the brake's powers when it saved the test train from otherwise certain collision with a horse-drawn dray on a level crossing, railways were at first slow to adopt it. Then in 1872 Westinghouse added to it the triple valve, which enabled the train pipe to charge reservoirs beneath each vehicle, from which the compressed air would apply the brakes when pressure in the train pipe was reduced. This meant that the brake was now automatic: if a train became divided, the brakes on both parts would be applied. From then on, more and more American railways adopted the Westinghouse brake and the Railroad Safety Appliance Act of 1893 made air brakes compulsory in the USA. Air brakes were also adopted in most other parts of the world, although only a minority of British railway companies took them up, the remainder, with insular reluctance, preferring the less effective vacuum brake.From 1880 Westinghouse was purchasing patents relating to means of interlocking railway signals and points; he combined them with his own inventions to produce a complete signalling system. The first really practical power signalling scheme, installed in the USA by Westinghouse in 1884, was operated pneumatically, but the development of railway signalling required an awareness of the powers of electricity, and it was probably this that first led Westinghouse to become interested in electrical processes and inventions. The Westinghouse Electric Company was formed in 1886: it pioneered the use of electricity distribution systems using high-voltage single-phase alternating current, which it developed from European practice. Initially this was violently opposed by established operators of direct-current distribution systems, but eventually the use of alternating current became widespread.[br]Principal Honours and DistinctionsLégion d'honneur.

9 Faraday, Michael
SUBJECT AREA: Electricity[br]b. 22 September 1791 Newington, Surrey, Englandd. 25 August 1867 London, England[br]English physicist, discoverer of the principles of the electric motor and dynamo.[br]Faraday's father was a blacksmith recently moved south from Westmorland. The young Faraday's formal education was limited to attendance at "a Common Day School", and then he worked as an errand boy for George Riebau, a bookseller and bookbinder in London's West End. Riebau subsequently took him as an apprentice bookbinder, and Faraday seized every opportunity to read the books that came his way, especially scientific works.A customer in the shop gave Faraday tickets to hear Sir Humphry Davy lecturing at the Royal Institution. He made notes of the lectures, bound them and sent them to Davy, asking for scientific employment. When a vacancy arose for a laboratory assistant at the Royal Institution, Davy remembered Faraday, who he took as his assistant on an 18- month tour of France, Italy and Switzerland (despite the fact that Britain and France were at war!). The tour, and especially Davy's constant company and readiness to explain matters, was a scientific education for Faraday, who returned to the Royal Institution as a competent chemist in his own right. Faraday was interested in electricity, which was then viewed as a branch of chemistry. After Oersted's announcement in 1820 that an electric current could affect a magnet, Faraday devised an arrangement in 1821 for producing continuous motion from an electric current and a magnet. This was the basis of the electric motor. Ten years later, after much thought and experiment, he achieved the converse of Oersted's effect, the production of an electric current from a magnet. This was magneto-electric induction, the basis of the electric generator.Electrical engineers usually regard Faraday as the "father" of their profession, but Faraday himself was not primarily interested in the practical applications of his discoveries. His driving motivation was to understand the forces of nature, such as electricity and magnetism, and the relationship between them. Faraday delighted in telling others about science, and studied what made a good scientific lecturer. At the Royal Institution he introduced the Friday Evening Discourses and also the Christmas Lectures for Young People, now televised in the UK every Christmas.[br]Bibliography1991, Curiosity Perfectly Satisfyed.

10 Planté, Raimond Louis Gaston
SUBJECT AREA: Electricity[br]b. 22 April 1834 Orthez, Franced. 21 May 1889 Paris, France[br]French physicist and inventor of a secondary electric cell from which was developed the widely used lead-acid storage battery.[br]After a scientific training at the Conservatoire des Arts et Métiers, Planté obtained an appointment as a Laboratory Assistant to Becquerel. Later, when he was employed as a chemist in the Parisian electroplating firm of Christofle et Cie, he carried out investigations into polarization in electrical cells, which led to his discovery of the lead-acid accumulator in 1859. This cell, with lead plates in an electrolyte of dilute sulphuric acid, had the characteristics of a storage device for electrical energy. Its performance was improved considerably if it was repeatedly charged and discharged, the active material being formed electrochemically from the lead of the plate itself. At the time of its discovery the Planté cell had little practical application and it was not until satisfactory dynamos were introduced that its commercial exploitation was possible. The cell was improved by Faure and later by Swan and others. The lead-acid cell became considerably important in the early days of electricity supply and later for electric traction and automobile use. The results of Planté's researches were communicated to the Academy of Sciences and published in various scientific periodicals. He devoted the last few years of his life to the study of atmospheric electricity.[br]Principal Honours and DistinctionsChevalier de la Légion d'honneur 1881.

He also discovered that certain mineral sulphide crystals would only conduct electricity in one direction, a rectification effect that made it possible to detect and demodulate radio signals in a more reliable manner than was possible with the coherer. Primarily, however, he was concerned with improving Marconi's radio transmitter to increase its broadcasting range. By using a transmitter circuit comprising a capacitor and a spark-gap, coupled to an aerial without a spark-gap, he was able to obtain much greater oscillatory currents in the latter, and by tuning the transmitter so that the oscillations occupied only a narrow frequency band he reduced the interference with other transmitters. Other achievements include the development of a directional aerial and the first practical wavemeter, and the measurement in Strasbourg of the strength of radio waves received from the Eiffel Tower transmitter in Paris. For all this work he subsequently shared with Marconi the 1909 Nobel Prize for Physics.Around 1895 he carried out experiments using a torsion balance in order to measure the universal gravitational constant, g, but the work for which he is probably best known is the addition of deflecting plates and a fluorescent screen to the Crooke's tube in 1897 in order to study the characteristics of high-frequency currents. The oscilloscope, as it was called, was not only the basis of a now widely used and highly versatile test instrument but was the forerunner of the cathode ray tube, or CRT, used for the display of radar and television images.At the beginning of the First World War, while in New York to testify in a patent suit, he was trapped by the entry of the USA into the war and remained in Brooklyn with his son until his death.[br]Principal Honours and DistinctionsNobel Prize for Physics (jointly with Marconi) 1909.Bibliography1874, "Assymetrical conduction of certain metal sulphides", Pogg.

12 Siemens, Sir Charles William
[br]b. 4 April 1823 Lenthe, Germanyd. 19 November 1883 London, England[br]German/British metallurgist and inventory pioneer of the regenerative principle and open-hearth steelmaking.[br]Born Carl Wilhelm, he attended craft schools in Lübeck and Magdeburg, followed by an intensive course in natural science at Göttingen as a pupil of Weber. At the age of 19 Siemens travelled to England and sold an electroplating process developed by his brother Werner Siemens to Richard Elkington, who was already established in the plating business. From 1843 to 1844 he obtained practical experience in the Magdeburg works of Count Stolburg. He settled in England in 1844 and later assumed British nationality, but maintained close contact with his brother Werner, who in 1847 had co-founded the firm Siemens \& Halske in Berlin to manufacture telegraphic equipment. William began to develop his regenerative principle of waste-heat recovery and in 1856 his brother Frederick (1826–1904) took out a British patent for heat regeneration, by which hot waste gases were passed through a honeycomb of fire-bricks. When they became hot, the gases were switched to a second mass of fire-bricks and incoming air and fuel gas were led through the hot bricks. By alternating the two gas flows, high temperatures could be reached and considerable fuel economies achieved. By 1861 the two brothers had incorporated producer gas fuel, made by gasifying low-grade coal.Heat regeneration was first applied in ironmaking by Cowper in 1857 for heating the air blast in blast furnaces. The first regenerative furnace was set up in Birmingham in 1860 for glassmaking. The first such furnace for making steel was developed in France by Pierre Martin and his father, Emile, in 1863. Siemens found British steelmakers reluctant to adopt the principle so in 1866 he rented a small works in Birmingham to develop his open-hearth steelmaking furnace, which he patented the following year. The process gradually made headway; as well as achieving high temperatures and saving fuel, it was slower than Bessemer's process, permitting greater control over the content of the steel. By 1900 the tonnage of open-hearth steel exceeded that produced by the Bessemer process.In 1872 Siemens played a major part in founding the Society of Telegraph Engineers (from which the Institution of Electrical Engineers evolved), serving as its first President. He became President for the second time in 1878. He built a cable works at Charlton, London, where the cable could be loaded directly into the holds of ships moored on the Thames. In 1873, together with William Froude, a British shipbuilder, he designed the Faraday, the first specialized vessel for Atlantic cable laying. The successful laying of a cable from Europe to the United States was completed in 1875, and a further five transatlantic cables were laid by the Faraday over the following decade.The Siemens factory in Charlton also supplied equipment for some of the earliest electric-lighting installations in London, including the British Museum in 1879 and the Savoy Theatre in 1882, the first theatre in Britain to be fully illuminated by electricity. The pioneer electric-tramway system of 1883 at Portrush, Northern Ireland, was an opportunity for the Siemens company to demonstrate its equipment.[br]Principal Honours and DistinctionsKnighted 1883.

13 Tesla, Nikola
SUBJECT AREA: Electricity[br]b. 9 July 1856 Smiljan, Croatiad. 7 January 1943 New York, USA[br]Serbian (naturalized American) engineer and inventor of polyphase electrical power systems.[br]While at the technical institute in Graz, Austria, Tesla's attention was drawn to the desirability of constructing a motor without a commutator. He considered the sparking between the commutator and brushes of the Gramme machine when run as a motor a serious defect. In 1881 he went to Budapest to work on the telegraph system and while there conceived the principle of the rotating magnetic field, upon which all polyphase induction motors are based. In 1882 Tesla moved to Paris and joined the Continental Edison Company. After building a prototype of his motor he emigrated to the United States in 1884, becoming an American citizen in 1889. He left Edison and founded an independent concern, the Tesla Electric Company, to develop his inventions.The importance of Tesla's first patents, granted in 1888 for alternating-current machines, cannot be over-emphasized. They covered a complete polyphase system including an alternator and induction motor. Other patents included the polyphase transformer, synchronous motor and the star connection of three-phase machines. These were to become the basis of the whole of the modern electric power industry. The Westinghouse company purchased the patents and marketed Tesla motors, obtaining in 1893 the contract for the Niagara Falls two-phase alternators driven by 5,000 hp (3,700 kW) water turbines.After a short period with Westinghouse, Tesla resigned to continue his research into high-frequency and high-voltage phenomena using the Tesla coil, an air-cored transformer. He lectured in America and Europe on his high-frequency devices, enjoying a considerable international reputation. The name "tesla" has been given to the SI unit of magnetic-flux density. The induction motor became one of the greatest advances in the industrial application of electricity. A claim for priority of invention of the induction motor was made by protagonists of Galileo Ferraris (1847–1897), whose discovery of rotating magnetic fields produced by alternating currents was made independently of Tesla's. Ferraris demonstrated the phenomenon but neglected its exploitation to produce a practical motor. Tesla himself failed to reap more than a small return on his work and later became more interested in scientific achievement than commercial success, with his patents being infringed on a wide scale.[br]Principal Honours and DistinctionsAmerican Institute of Electrical Engineers Edison Medal 1917.

15 Sperry, Elmer Ambrose
[br]b. 21 October 1860 Cincinnatus, Cortland County, New York, USAd. 16 June 1930 Brooklyn, New York, USA[br]American entrepreneur who invented the gyrocompass.[br]Sperry was born into a farming community in Cortland County. He received a rudimentary education at the local school, but an interest in mechanical devices was aroused by the agricultural machinery he saw around him. His attendance at the Normal School in Cortland provided a useful theoretical background to his practical knowledge. He emerged in 1880 with an urge to pursue invention in electrical engineering, then a new and growing branch of technology. Within two years he was able to patent and demonstrate his arc lighting system, complete with its own generator, incorporating new methods of regulating its output. The Sperry Electric Light, Motor and Car Brake Company was set up to make and market the system, but it was difficult to keep pace with electric-lighting developments such as the incandescent lamp and alternating current, and the company ceased in 1887 and was replaced by the Sperry Electric Company, which itself was taken over by the General Electric Company.In the 1890s Sperry made useful inventions in electric mining machinery and then in electric street-or tramcars, with his patent electric brake and control system. The patents for the brake were important enough to be bought by General Electric. From 1894 to 1900 he was manufacturing electric motor cars of his own design, and in 1900 he set up a laboratory in Washington, where he pursued various electrochemical processes.In 1896 he began to work on the practical application of the principle of the gyroscope, where Sperry achieved his most notable inventions, the first of which was the gyrostabilizer for ships. The relatively narrow-hulled steamship rolled badly in heavy seas and in 1904 Ernst Otto Schuck, a German naval engineer, and Louis Brennan in England began experiments to correct this; their work stimulated Sperry to develop his own device. In 1908 he patented the active gyrostabilizer, which acted to correct a ship's roll as soon as it started. Three years later the US Navy agreed to try it on a destroyer, the USS Worden. The successful trials of the following year led to widespread adoption. Meanwhile, in 1910, Sperry set up the Sperry Gyroscope Company to extend the application to commercial shipping.At the same time, Sperry was working to apply the gyroscope principle to the ship's compass. The magnetic compass had worked well in wooden ships, but iron hulls and electrical machinery confused it. The great powers' race to build up their navies instigated an urgent search for a solution. In Germany, Anschütz-Kämpfe (1872–1931) in 1903 tested a form of gyrocompass and was encouraged by the authorities to demonstrate the device on the German flagship, the Deutschland. Its success led Sperry to develop his own version: fortunately for him, the US Navy preferred a home-grown product to a German one and gave Sperry all the backing he needed. A successful trial on a destroyer led to widespread acceptance in the US Navy, and Sperry was soon receiving orders from the British Admiralty and the Russian Navy.In the rapidly developing field of aeronautics, automatic stabilization was becoming an urgent need. In 1912 Sperry began work on a gyrostabilizer for aircraft. Two years later he was able to stage a spectacular demonstration of such a device at an air show near Paris.Sperry continued research, development and promotion in military and aviation technology almost to the last. In 1926 he sold the Sperry Gyroscope Company to enable him to devote more time to invention.[br]Principal Honours and DistinctionsJohn Fritz Medal 1927. President, American Society of Mechanical Engineers 1928.BibliographySperry filed over 400 patents, of which two can be singled out: 1908. US patent no. 434,048 (ship gyroscope); 1909. US patent no. 519,533 (ship gyrocompass set).Further ReadingT.P.Hughes, 1971, Elmer Sperry, Inventor and Engineer, Baltimore: Johns Hopkins University Press (a full and well-documented biography, with lists of his patents and published writings).LRD -
16 Swan, Sir Joseph Wilson
[br]b. 31 October 1828 Sunderland, Englandd. 27 May 1914 Warlingham, Surrey, England[br]English chemist, inventor in Britain of the incandescent electric lamp and of photographic processes.[br]At the age of 14 Swan was apprenticed to a Sunderland firm of druggists, later joining John Mawson who had opened a pharmacy in Newcastle. While in Sunderland Swan attended lectures at the Athenaeum, at one of which W.E. Staite exhibited electric-arc and incandescent lighting. The impression made on Swan prompted him to conduct experiments that led to his demonstration of a practical working lamp in 1879. As early as 1848 he was experimenting with carbon as a lamp filament, and by 1869 he had mounted a strip of carbon in a vessel exhausted of air as completely as was then possible; however, because of residual air, the filament quickly failed.Discouraged by the cost of current from primary batteries and the difficulty of achieving a good vacuum, Swan began to devote much of his attention to photography. With Mawson's support the pharmacy was expanded to include a photographic business. Swan's interest in making permanent photographic records led him to patent the carbon process in 1864 and he discovered how to make a sensitive dry plate in place of the inconvenient wet collodian process hitherto in use. He followed this success with the invention of bromide paper, the subject of a British patent in 1879.Swan resumed his interest in electric lighting. Sprengel's invention of the mercury pump in 1865 provided Swan with the means of obtaining the high vacuum he needed to produce a satisfactory lamp. Swan adopted a technique which was to become an essential feature in vacuum physics: continuing to heat the filament during the exhaustion process allowed the removal of absorbed gases. The inventions of Gramme, Siemens and Brush provided the source of electrical power at reasonable cost needed to make the incandescent lamp of practical service. Swan exhibited his lamp at a meeting in December 1878 of the Newcastle Chemical Society and again the following year before an audience of 700 at the Newcastle Literary and Philosophical Society. Swan's failure to patent his invention immediately was a tactical error as in November 1879 Edison was granted a British patent for his original lamp, which, however, did not go into production. Parchmentized thread was used in Swan's first commercial lamps, a material soon superseded by the regenerated cellulose filament that he developed. The cellulose filament was made by extruding a solution of nitro-cellulose in acetic acid through a die under pressure into a coagulating fluid, and was used until the ultimate obsolescence of the carbon-filament lamp. Regenerated cellulose became the first synthetic fibre, the further development and exploitation of which he left to others, the patent rights for the process being sold to Courtaulds.Swan also devised a modification of Planté's secondary battery in which the active material was compressed into a cellular lead plate. This has remained the central principle of all improvements in secondary cells, greatly increasing the storage capacity for a given weight.[br]Principal Honours and DistinctionsKnighted 1904.

20 Duddell, William du Bois
SUBJECT AREA: Electricity[br]b. 1872 Kensington, London, Englandd. 4 November 1917 London, England[br]English engineer, inventor of the first practical oscillograph.[br]After an education at the College of Stanislas, Cannes, Duddell served an apprenticeship with Davy Paxman of Colchester. Studying under Ayrton and Mather at the Central Technical College in South Kensington, he found the facilities for experimental work of exceptional value to him and remained there for some years. In 1897 Duddell produced a galvanometer which was sufficiently responsive to display an alternating-current wave-form. This instrument, with a coil carrying a mirror in the air gap of a powerful electromagnet, had a small periodic time. An oscillating mirror driven by a synchronous motor spread out the deflection on a time-scale. This development became the first commercial oscillograph and brought Duddell into prominence as a first-rate designer of special instruments. The Duddell oscillograph remained in use until after the Second World War, examples being used for recording short-circuit tests on high-power switchgear and other rapidly varying or transient phenomena. His next important work was to collaborate with Professor Marchant at Liverpool University to investigate the characteristics of the electric arc. This led to the suggestion that, coupled to a resonant circuit, the electric arc could form a generator of high-frequency currents. This arrangement was later developed by Poulson for wireless telegraphy. Duddell spent the last years of his life on government research as a member of the Admiralty Board of Inventions and Research and also of the Inventions Board of the Ministry of Munitions.[br]Principal Honours and DistinctionsCBE 1916.
