    [br]
    b. 26 June 1911 Stockport, Cheshire, England
    d. 11 August 1977 Prestbury, Cheshire, England
    [br]
    English electrical engineer who invented the Williams storage cathode ray tube, which was extensively used worldwide as a data memory in the first digital computers.
    [br]
    Following education at Stockport Grammar School, Williams entered Manchester University in 1929, gaining his BSc in 1932 and MSc in 1933. After a short time as a college apprentice with Metropolitan Vickers, he went to Magdalen College, Oxford, to study for a DPhil, which he was awarded in 1936. He returned to Manchester University that year as an assistant lecturer, gaining his DSc in 1939. Following the outbreak of the Second World War he worked for the Scientific Civil Service, initially at the Bawdsey Research Station and then at the Telecommunications Research Establishment at Malvern, Worcestershire. There he was involved in research on non-incandescent amplifiers and diode rectifiers and the development of the first practical radar system capable of identifying friendly aircraft. Later in the war, he devised an automatic radar system suitable for use by fighter aircraft.
    After the war he resumed his academic career at Manchester, becoming Professor of Electrical Engineering and Director of the University Electrotechnical Laboratory in 1946. In the same year he succeeded in developing a data-memory device based on the cathode ray tube, in which the information was stored and read by electron-beam scanning of a charge-retaining target. The Williams storage tube, as it became known, not only found obvious later use as a means of storing single-frame, still television images but proved to be a vital component of the pioneering Manchester University MkI digital computer. Because it enabled both data and program instructions to be stored in the computer, it was soon used worldwide in the development of the early stored-program computers.

    English mechanical engineer, engineering teacher and researcher.
    [br]
    James John Guest was educated at Marlborough in 1880–4 and at Trinity College, Cambridge, graduating as fifth wrangler in 1888. He received practical training in several workshops and spent two years in postgraduate work at the Engineering Department of Cambridge University. After working as a draughtsman in the machine-tool, hydraulic and crane departments of Tangyes Ltd at Birmingham, he was appointed in 1896 Assistant Professor of Engineering at McGill University in Canada. After a short time he moved to the Polytechnic Institute at Worcester, Massachusetts, where he was for three years Professor of Mechanical Engineering and Head of the Engineering Department. In 1899 he returned to Britain and set up as a consulting engineer in Birmingham, being a partner in James J.Guest \& Co. For the next fifteen years he combined this work with research on grinding phenomena. He also developed a theory of grinding which he first published in a paper at the British Association for the Advancement of Science in 1914 and elaborated in a paper to the Institution of Mechanical Engineers and in his book Grinding Machinery (1915). During the First World War, in 1916–17, he was in charge of inspection in the Staffordshire and Shropshire Area, Ministry of Munitions. In 1917 he returned to teaching as Reader in Graphics and Structural Engineering at University College London. His final appointment was about 1923 as Professor of Mechanical and Electrical Engineering, Artillery College, Woolwich, which later became the Military College of Science.
    He carried out research on the strength of materials and contributed many articles on the subject to the technical press. He originated Guest's Law for a criterion of failure of materials under combined stresses, first published in 1900. He was a Member of the Institution of Mechanical Engineers in 1900–6 and from 1919 and contributed to their proceedings in many discussions and two major papers.

    b. 12 March 1790 London, England
    d. 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.

  • 5 Bateman, John Frederick La Trobe

    [br]
    b. 30 May 1810 Lower Wyke, near Halifax, Yorkshire, England
    d. 10 June 1889 Moor Park, Farnham, Surrey, England
    [br]
    English civil engineer whose principal works were concerned with reservoirs, water-supply schemes and pipelines.
    [br]
    Bateman's maternal grandfather was a Moravian missionary, and from the age of 7 he was educated at the Moravian schools at Fairfield and Ockbrook. At the age of 15 he was apprenticed to a "civil engineer, land surveyor and agent" in Oldham. After this apprenticeship, Bateman commenced his own practice in 1833. One of his early schemes and reports was in regard to the flooding of the river Medlock in the Manchester area. He came to the attention of William Fairbairn, the engine builder and millwright of Canal Street, Ancoats, Manchester. Fairbairn used Bateman as his site surveyor and as such he prepared much of the groundwork for the Bann reservoirs in Northern Ireland. Whilst the reports on the proposals were in the name of Fairbairn, Bateman was, in fact, appointed by the company as their engineer for the execution of the works. One scheme of Bateman's which was carried forward was the Kendal Reservoirs. The Act for these was signed in 1845 and was implemented not for the purpose of water supply but for the conservation of water to supply power to the many mills which stood on the river Kent between Kentmere and Morecambe Bay. The Kentmere Head dam is the only one of the five proposed for the scheme to survive, although not all the others were built as they would have retained only small volumes of water.
    Perhaps the greatest monument to the work of J.F.La Trobe Bateman is Manchester's water supply; he was consulted about this in 1844, and construction began four years later. He first built reservoirs in the Longdendale valley, which has a very complicated geological stratification. Bateman favoured earth embankment dams and gravity feed rather than pumping; the five reservoirs in the valley that impound the river Etherow were complex, cored earth dams. However, when completed they were greatly at risk from landslips and ground movement. Later dams were inserted by Bateman to prevent water loss should the older dams fail. The scheme was not completed until 1877, by which time Manchester's population had exceeded the capacity of the original scheme; Thirlmere in Cumbria was chosen by Manchester Corporation as the site of the first of the Lake District water-supply schemes. Bateman, as Consulting Engineer, designed the great stone-faced dam at the west end of the lake, the "gothic" straining well in the middle of the east shore of the lake, and the 100-mile (160 km) pipeline to Manchester. The Act for the Thirlmere reservoir was signed in 1879 and, whilst Bateman continued as Consulting Engineer, the work was supervised by G.H. Hill and was completed in 1894.
    Bateman was also consulted by the authorities in Glasgow, with the result that he constructed an impressive water-supply scheme derived from Loch Katrine during the years 1856–60. It was claimed that the scheme bore comparison with "the most extensive aqueducts in the world, not excluding those of ancient Rome". Bateman went on to superintend the waterworks of many cities, mainly in the north of England but also in Dublin and Belfast. In 1865 he published a pamphlet, On the Supply of Water to London from the Sources of the River Severn, based on a survey funded from his own pocket; a Royal Commission examined various schemes but favoured Bateman's.
    Bateman was also responsible for harbour and dock works, notably on the rivers Clyde and Shannon, and also for a number of important water-supply works on the Continent of Europe and beyond. Dams and the associated reservoirs were the principal work of J.F.La Trobe Bateman; he completed forty-three such schemes during his professional career. He also prepared many studies of water-supply schemes, and appeared as professional witness before the appropriate Parliamentary Committees.

    b. 23 August 1875 Ulverston, Cumbria, England
    d. 27 April 1966 Oxford, England
    [br]
    English physicist who made important contributions to the development of radio communications.
    [br]
    After early education at home and at private school, Eccles won a scholarship to the Royal College of Science (now Imperial College), London, where he gained a First Class BSc in physics in 1898. He then worked as a demonstrator at the college and studied coherers, for which he obtained a DSc in 1901. Increasingly interested in electrical engineering, he joined the Marconi Company in 1899 to work on oscillators at the Poole experimental radio station, but in 1904 he returned to academic life as Professor of Mathematics and Physics and Department Head at South West Polytechnic, Chelsea. There he discovered ways of using the negative resistance of galena-crystal detectors to generate oscillations and gave a mathematical description of the operation of the triode valve. In 1910 he became Reader in Engineering at University College, London, where he published a paper explaining the reflection of radio waves by the ionosphere and designed a 60 MHz short-wave transmitter. From 1916 to 1926 he was Professor of Applied Physics and Electrical Engineering at the Finsbury City \& Guilds College and a private consulting engineer. During the First World War he was a military scientific adviser and Secretary to the Joint Board of Scientific Societies. After the war he made many contributions to electronic-circuit development, many of them (including the Eccles-Jordan "flip-flop" patented in 1918 and used in binary counters) in conjunction with F.W.Jordan, about whom little seems to be known. Illness forced Eccles's premature academic retirement in 1926, but he remained active as a consultant for many years.

    English photographic scientist, inventor and author.
    [br]
    Abney began his career as an officer in the Army and was an instructor in chemistry in the Royal Engineers at Chatham, where he made substantial use of photography as a working tool. He retired from the Army in 1877 and joined the Science and Art Department at South Kensington. It was at Abney's suggestion that a collection of photographic equipment and processes was established in the South Kensington Museum (later to become the Science Museum Photography Collection).
    Abney undertook significant researches into the nature of gelatine silver halide emulsions at a time when they were being widely adopted by photographers. Perhaps his most important practical innovations were the introduction of hydroquinone as a developing agent in 1880 and silver gelatine citrochloride emulsions for printing-out paper (POP) in 1882. However, Abney was at the forefront of many aspects of photographic research during a period of great innovation and change in photography. He devised new techniques of photomechanical printing and conducted significant researches in the fields of photochemistry and spectral analysis. Abney published throughout his career for both the specialist scientist and the more general photographic practitioner.

    d. 9 February 1979 London, England
    [br]
    Hungarian (naturalized British) physicist, inventor of holography.
    [br]
    Gabor became interested in physics at an early age. Called up for military service in 1918, he was soon released when the First World War came to an end. He then began a mechanical engineering course at the Budapest Technical University, but a further order to register for military service prompted him to flee in 1920 to Germany, where he completed his studies at Berlin Technical University. He was awarded a Diploma in Engineering in 1924 and a Doctorate in Electrical Engineering in 1927. He then went on to work in the physics laboratory of Siemens \& Halske. He returned to Hungary in 1933 and developed a new kind of fluorescent lamp called the plasma lamp. Failing to find a market for this device, Gabor made the decision to abandon his homeland and emigrate to England. There he joined British Thompson-Houston (BTH) in 1934 and married a colleague from the company in 1936. Gabor was also unsuccessful in his attempts to develop the plasma lamp in England, and by 1937 he had begun to work in the field of electron optics. His work was interrupted by the outbreak of war in 1939, although as he was not yet a British subject he was barred from making any significant contribution to the British war effort. It was only when the war was near its end that he was able to return to electron optics and begin the work that led to the invention of holography. The theory was developed during 1947 and 1948; Gabor went on to demonstrate that the theories worked, although it was not until the invention of the laser in 1960 that the full potential of his invention could be appreciated. He coined the term "hologram" from the Greek holos, meaning complete, and gram, meaning written. The three-dimensional images have since found many applications in various fields, including map making, medical imaging, computing, information technology, art and advertising. Gabor left BTH to become an associate professor at the Imperial College of Science and Technology in 1949, a position he held until his retirement in 1967. In 1971 he was awarded the Nobel Prize for Physics for his work on holography.

    [br]
    b. 1833 Manchester, England
    d. 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.

    Scottish Colonel-Commandant, Royal Engineers.
    [br]
    At first he was educated by Andrew Little of Lan-gholm. At the age of 14 he was sent to school at Selkirk, where he stayed for two years until joining the Royal Military Academy at Woolwich in August 1796. He was commissioned as Second Lieutenant in the Royal Artillery and transferred to the Royal Engineers on 1 April 1798. He served at Minorca, Malta, Naples, Sicily, Calabria and in the siege of Copenhagen and in other campaigns. He was promoted First Captain in 1807, and was on the staff of Sir John Moore at the battle of Coruna. He was wounded at the siege of Flushing in 1809 and was invalided for a year, employing his time in learning German.
    In November 1810 he published his Essay on Military Policy and Institutions of the British Empire, which ran through four editions. In 1811 he was in command of a company of Royal Military Artificers at Plymouth and there he devised a method of education by which the NCOs and troops could teach themselves without "mathematical masters". His system was a great success and was adopted at Chatham and throughout the corps. In 1812 he was appointed Director of the School of Military Engineering at Chatham. He remained at Chatham until 1841, when he was appointed Inspector-General of Railways. During this period he organized improved systems of sapping, mining, telegraphing, pontooning and exploding gunpowder on land or under water, and prepared pamphlets and courses of instruction in these and other subjects. In May 1836 he started what is probably the most important work for which he is remembered. This, was a book on Limes, Calcareous Cements, Mortar, Stuccos and Concretes. The general adoption of Joseph Aspdin's Portland Cement was largely due to Pasley's recommendation of the material.
    He was married twice: first in 1814 at Chatham to Harriet Cooper; and then on 30 March 1819 at Rochester to Martha Matilda Roberts, with whom he had six children— she died in 1881.

    [br]
    English physicist who was jointly responsible for the construction of the EDS AC computer.
    [br]
    Educated at King Edward VI Grammar School, Stourbridge, where he began to make radio sets and read Wireless World, Wilkes went to St John's College, Cambridge, in 1931, graduating as a Wrangler in the Mathematical Tripos in 1934. He then carried out research at the Cavendish Laboratory, becoming a demonstrator in 1937. During the Second World War he worked on radar, differential analysers and operational research at the Bawdsey Research Station and other air-defence establishments. In 1945 he returned to Cambridge as a lecturer and as Acting Director of the Mathematical (later Computer) Laboratory, serving as Director from 1946 to 1970.
    During the late 1940s, following visits to the USA for computer courses and to see the ENIAC computer, with the collaboration of colleagues he constructed the Cambridge University digital computer EDSAC (for Electronic Delay Storage Automatic Computer), using ultrasonic delay lines for data storage. In the mid-1950s a second machine, EDSAC2, was constructed using a magnetic-core memory. In 1965 he became Professor of Computer Technology. After retirement he worked for the Digital Electronic Corporation (DEC) from 1981 to 1986, serving also as Adjunct Professor of Computer Science and Electrical Engineering at the Massachusetts Institute of Technology from 1981 to 1985. In 1990 he became a research strategy consultant to the Olivetti Research Directorate.

    [br]
    b. 15 February 1834 Bryn Helen, Gwynedd, Wales
    d. 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.

    d. 18 June 1861 near Manchester, England
    [br]
    English engineer who devised d new form of cast-iron girder.
    [br]
    Eaton Hodgkinson's father, a farmer, died when he was 6 years old, but his mother was a resourceful woman who set up a business in Salford and ensured that her son received a sound schooling. Most important for his education, however, was his friendship with the Manchester scientific luminary Dr. Dalton, who instructed him in practical mathematics. These studies led Hodgkinson to devise a new form of cast-iron girder, carefully tested by experiments and which was widely adopted for fire-proof structures in the nineteenth century. Following Dalton, Hodgkinson became an active member of the Manchester Philosophical Society, of which he was elected President in 1848. He also became an active member of the British Association for the Advancement of Science. Hodgkinson's work on cast-iron girders secured him a Fellowship of the Royal Society, and the Royal Medal of the Society, in 1841. It was Hodgkinson also who verified the mathematical value of the pioneering experiments carried out by William Fairbairn for Robert Stephenson's proposed wrought-iron tube structure which, in 1849, became the Britannia Bridge over the Menai Straits. He received a Silver Medal for this work at the Paris Exhibition of 1858. Hodgkinson served as a member of the Royal Commission appointed to enquire into the application of iron to railway structures. In 1847 he was appointed Professor of the Mechanical Principles of Engineering at University College, London, but his health began to fail shortly after. He was elected an Honorary Member of the Institution of Civil Engineers in 1851. Described as "singularly simple and guileless", he was widely admired and respected.

    b. 2 June 1910 Sheffield, England
    d. 3 September 1979 Bristol, England
    [br]
    English scientist and inventor of the multi-speed induction motor using the pole amplitude modulation principle.
    [br]
    After graduating from Keble College, Oxford, Rawcliffe joined the Metropolitan Vickers Electrical Company in 1932 as a college apprentice, and later became a design engineer. This was followed by a period as a lecturer at Liverpool University, where he was able to extend his knowledge of the principles underlying the design and operation of electrical machines. In 1941 he became Head of the Electrical Engineering Department at the Robert Gordon Technical College, Aberdeen, and Lecturer in charge of Electrical Engineering at Aberdeen University. In 1944 Rawcliffe was appointed to the Chair of Electrical Engineering at the University of Bristol, where he remained until his retirement in 1975. The reputation of his department was enhanced by the colleagues he recruited.
    After 1954 he began research into polyphase windings, the basis of alternating-current machinery, and published papers concerned with the dual problems of frequency changing and pole changing. The result of this research was the discovery in 1957 of a technique for making squirrel-cage induction motors run at more than one speed. By reversing current in one part of the winding, the pole distribution and number were changed, and with it the speed of rotation.
    Rawcliffe's name became synonymous with pole amplitude modulation, or PAM, the name given to this technique. Described by Rawcliffe as a new philosophy of windings, the technique led to a series of research papers, patents and licensing agreements in addition to consultancies to advise on application problems. Commercial exploitation of the new idea throughout Western Europe, the United Kingdom and the United States followed. In total he contributed twentyfive papers to the Proceedings of the Institution of Electrical Engineers and some sixty British patent applications were filed.

    [br]
    b. 6 September 1892 Bradford, England
    d. 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.

    SUBJECT AREA: Civil engineering
    [br]
    b. c. 1700 probably near Northampton, England
    d. 24 January 1781 London, England
    [br]
    English surveyor and civil engineer.
    [br]
    Very little is known of his early life, but he was clearly a skilful and gifted engineer who had received comprehensive practical training, for in 1743 he erected the machinery in the world's first water-powered cotton mill at Northampton on the river Nene. In 1748 he invented a weighing machine for use by turnpike trusts for weighing wagons. Until 1757 he remained in Northampton, mainly surveying enclosures and turnpike roads and making agricultural machinery. He also gained a national reputation for building and installing very successful ventilating equipment (invented by Dr Stephen Hales) in hospitals, prisons and ships, including some ventilators of Yeoman's own design in the Houses of Parliament.
    Meanwhile he developed an interest in river improvements, and in 1744 he made his first survey of the River Nene between Thrapston and Northampton; he repeated the survey in 1753 and subsequently gave evidence in parliamentary proceedings in 1756. The following year he was in Gloucestershire surveying the line of the Stroudwater Canal, an operation that he repeated in 1776. Also in 1757, he was appointed Surveyor to the River Ivel Navigation in Bedfordshire. In 1761 he was back on the Nene. During 1762–5 he carried out surveys for the Chelmer \& Blackwater Navigation, although the work was not undertaken for another thirty years. In 1765 he reported on land-drainage improvements for the Kentish Sour. It was at this time that he became associated with John Smeaton in a major survey in 1766 of the river Lea for the Lee Navigation Trustees, having already made some surveys with Joseph Nickalls near Waltham Abbey in 1762. Yeoman modified some of Smeaton's proposals and on 1 July 1767 was officially appointed Surveyor to the Lee Navigation Trustees, a post he retained until 1771. He also advised on the work to create the Stort Navigation, and at the official opening on 24 October 1769 he made a formal speech announcing: "Now is Bishops Stortford open to all the ports of the world." Among his other works were: advice on Ferriby Sluice on the River Ancholme (1766); reports on the Forth \& Clyde Canal, the North Level and Wisbech outfall on the Nene, the Coventry Canal, and estimates for the Leeds and Selby Canal (1768–71); estimates for the extension of the Medway Navigation from Tonbridge to Edenbridge (1771); and between 1767 and 1777 he was consulted, with other engineers, by the City of London on problems regarding the Thames.
    He joined the Northampton Philosophical Society shortly after its formation in 1743 and was President several times before he moved to London. In 1760 he became a member of the Society for the Encouragement of Arts, Manufactures and Commerce, and in 1763 he was chosen as joint Chairman of the Committee on Mechanics—a position he held until 1778. He was elected a Fellow of the Royal Society on 12 January 1764. On the formation of the Smeatonian Society of Civil Engineers, the forerunner of the present Institution of Civil Engineers, he was elected first President in 1771, remaining as such until his illness in 1780.

    English inventor and gas engineer.
    [br]
    Clegg received scientific instruction from John Dalton, the founder of the atomic theory, and was apprenticed to Boulton \& Watt. While at their Soho factory in Birmingham, he assisted William Murdock with his experiments on coal gas. He left the firm in 1804 and set up as a gas engineer on his own account. He designed and installed gas plant and lighting in a number of factories, including Henry Lodge's cotton mill at Sowerby Bridge and in 1811 the Jesuit College at Stoneyhurst in Lancashire, the first non-industrial establishment to be equipped with gas lighting.
    Clegg moved to London in 1813 and successfully installed gas lighting at the premises of Rudolf Ackermann in the Strand. His success in the manufacture of gas had earned him the Royal Society of Arts Silver Medal in 1808 for furthering "the art of gas production", and in 1813 it brought him the appointment of Chief Engineer to the first gas company, the Chartered Gas, Light \& Coke Company. He left in 1817, but remained in demand to set up gas works and advise on the formation of gas companies. Throughout this time there flowed from Clegg a series of inventions of fundamental importance in the gas industry. While at Lodge's mill he had begun purifying gas by adding lime to the gas holder, and at Stoneyhurst this had become a separate lime purifier. In 1815, and again in 1818, Clegg patented the wet-meter which proved to be the basis for future devices for measuring gas. He invented the gas governor and, favouring the horizontal retort, developed the form which was to become standard for the next forty years. But after all this, Clegg joined a concern in Liverpool which failed, taking all his possessions with it. He made a fresh start in Lisbon, where he undertook various engineering works for the Portuguese government. He returned to England to find railway construction gathering pace, but he again backed a loser by engaging in the ill-fated atmospheric-rail way project. He was finally discouraged from taking part in further enterprises, but he received a government appointment as Surveying Officer to conduct enquiries in connection with the various Bills on gas that were presented to Parliament. Clegg also contributed to his son's massive treatise on the manufacture of coal gas.

    [br]
    [br]
    Rankine was educated at Ayr Academy and Glasgow High School, although he appears to have learned much of his basic mathematics and physics through private study. He attended Edinburgh University and then assisted his father, who was acting as Superintendent of the Edinburgh and Dalkeith Railway. This introduction to engineering practice was followed in 1838 by his appointment as a pupil to Sir John MacNeill, and for the next four years he served under MacNeill on his Irish railway projects. While still in his early twenties, Rankine presented pioneering papers on metal fatigue and other subjects to the Institution of Civil Engineers, for which he won a prize, but he appears to have resigned from the Civils in 1857 after an argument because the Institution would not transfer his Associate Membership into full Membership. From 1844 to 1848 Rankine worked on various projects for the Caledonian Railway Company, but his interests were becoming increasingly theoretical and a series of distinguished papers for learned societies established his reputation as a leading scholar in the new science of thermodynamics. He was elected Fellow of the Royal Society in 1853. At the same time, he remained intimately involved with practical questions of applied science, in shipbuilding, marine engineering and electric telegraphy, becoming associated with the influential coterie of fellow Scots such as the Thomson brothers, Napier, Elder, and Lewis Gordon. Gordon was then the head of a large and successful engineering practice, but he was also Regius Professor of Engineering at the University of Glasgow, and when he retired from the Chair to pursue his business interests, Rankine, who had become his Assistant, was appointed in his place.
    From 1855 until his premature death in 1872, Rankine built up an impressive engineering department, providing a firm theoretical basis with a series of text books that he wrote himself and most of which remained in print for many decades. Despite his quarrel with the Institution of Civil Engineers, Rankine took a keen interest in the institutional development of the engineering profession, becoming the first President of the Institution of Engineers and Shipbuilders in Scotland, which he helped to establish in 1857. Rankine campaigned vigorously for the recognition of engineering studies as a full university degree at Glasgow, and he achieved this in 1872, the year of his death. Rankine was one of the handful of mid-nineteenth century engineers who virtually created engineering as an academic discipline.

    b. 6 September 1908 Nottingham, England
    [br]
    English physicist who produced the first practical caesium atomic clock, which was later used to define the second.
    [br]
    Louis Essen joined the National Physical Laboratory (NPL) at Teddington in 1927 after graduating from London University. He spent his whole working life at the NPL and retired in 1972; his research there was recognized by the award of a DSc in 1948. At NPL he joined a team working on the development of frequency standards using quartz crystals and he designed a very successful quartz oscillator, which became known as the "Essen ring". He was also involved with radio frequency oscillators. His expertise in these fields was to play a crucial role in the development of the caesium clock. The idea of an atomic clock had been proposed by I.I.Rabbi in 1945, and an instrument was constructed shortly afterwards at the National Bureau of Standards in the USA. However, this device never realized the full potential of the concept, and after seeing it on a visit to the USA Essen was convinced that a more successful instrument could be built at Teddington. Assisted by J.V.L.Parry, he commenced work in the spring of 1953 and by June 1955 the clock was working reliably, with an accuracy that was equivalent to one second in three hundred years. This was significantly more accurate than the astronomical observations that were used at that time to determine the second: in 1967 the second was redefined in terms of the value for the frequency of vibration of caesium atoms that had been obtained with this clock.
