  • 2 Colpitts, Edwin Henry

    [br]
    b. 9 January 1872 Pointe de Bute, Canada
    d. 6 March 1949 Orange, New Jersey, USA
    [br]
    Canadian physicist and electrical engineer responsible for important developments in electronic-circuit technology.
    [br]
    Colpitts obtained Bachelor's degrees at Mount Allison University, Sackville, New Brunswick, and Harvard in 1894 and 1896, respectively, followed by a Master's degree at Harvard in 1897. After two years as assistant to the professor of physics there, he joined the American Bell Telephone Company. When the Bell Company was reorganized in 1907, he moved to the Western Electric branch of the company in New York as Head of the Physical Laboratories. In 1911 he became a director of the Research Laboratories, and in 1917 he became Assistant Chief Engineer of the company. During this time he invented both the push-pull amplifier and the Colpitts oscillator, both major developments in communications. In 1917, during the First World War, he spent some time in France helping to set up the US Signal Corps Research Laboratories. Afterwards he continued to do much, both technically and as a manager, to place telephone communications on a firm scientific basis, retiring as Vice-President of the Bell Telephone Laboratories in 1937. With the outbreak of the Second World War in 1941 he was recalled from retirement and appointed Director of the Engineering Foundation to work on submarine warfare techniques, particularly echo-ranging.

  • 7 Davy, Sir Humphry

    [br]
    b. 17 December 1778 Penzance, Cornwall, England
    d. 29 May 1829 Geneva, Switzerland
    [br]
    English chemist, discoverer of the alkali and alkaline earth metals and the halogens, inventor of the miner's safety lamp.
    [br]
    Educated at the Latin School at Penzance and from 1792 at Truro Grammar School, Davy was apprenticed to a surgeon in Penzance. In 1797 he began to teach himself chemistry by reading, among other works, Lavoisier's elementary treatise on chemistry. In 1798 Dr Thomas Beddoes of Bristol engaged him as assistant in setting up his Pneumatic Institution to pioneer the medical application of the newly discovered gases, especially oxygen.
    In 1799 he discovered the anaesthetic properties of nitrous oxide, discovered not long before by the chemist Joseph Priestley. He also noted its intoxicating qualities, on account of which it was dubbed "laughing-gas". Two years later Count Rumford, founder of the Royal Institution in 1800, appointed Davy Assistant Lecturer, and the following year Professor. His lecturing ability soon began to attract large audiences, making science both popular and fashionable.
    Davy was stimulated by Volta's invention of the voltaic pile, or electric battery, to construct one for himself in 1800. That enabled him to embark on the researches into electrochemistry by which is chiefly known. In 1807 he tried decomposing caustic soda and caustic potash, hitherto regarded as elements, by electrolysis and obtained the metals sodium and potassium. He went on to discover the metals barium, strontium, calcium and magnesium by the same means. Next, he turned his attention to chlorine, which was then regarded as an oxide in accordance with Lavoisier's theory that oxygen was the essential component of acids; Davy failed to decompose it, however, even with the aid of electricity and concluded that it was an element, thus disproving Lavoisier's view of the nature of acids. In 1812 Davy published his Elements of Chemical Philosophy, in which he presented his chemical ideas without, however, committing himself to the atomic theory, recently advanced by John Dalton.
    In 1813 Davy engaged Faraday as Assistant, perhaps his greatest service to science. In April 1815 Davy was asked to assist in the development of a miner's lamp which could be safely used in a firedamp (methane) laden atmosphere. The "Davy lamp", which emerged in January 1816, had its flame completely surrounded by a fine wire mesh; George Stephenson's lamp, based on a similar principle, had been introduced into the Northumberland pits several months earlier, and a bitter controversy as to priority of invention ensued, but it was Davy who was awarded the prize for inventing a successful safety lamp.
    In 1824 Davy was the first to suggest the possibility of conferring cathodic protection to the copper bottoms of naval vessels by the use of sacrificial electrodes. Zinc and iron were found to be equally effective in inhibiting corrosion, although the scheme was later abandoned when it was found that ships protected in this way were rapidly fouled by weeds and barnacles.

    [br]
    b. 24 July 1866 Handsworth, Birmingham, England
    d. 11 June 1956 Virginia Water, Surrey, England
    [br]
    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.

    [br]
    b. 16 December 1917 Minehead, Somerset, England
    [br]
    English writer of science fiction who correctly predicted the use of geo-stationary earth satellites for worldwide communications.
    [br]
    Whilst still at Huish's Grammar School, Taunton, Clarke became interested in both space science and science fiction. Unable to afford a scientific education at the time (he later obtained a BSc at King's College, London), he pursued both interests in his spare time while working in the Government Exchequer and Audit Department between 1936 and 1941. He was a founder member of the British Interplanetary Society, subsequently serving as its Chairman in 1946–7 and 1950–3. From 1941 to 1945 he served in the Royal Air Force, becoming a technical officer in the first GCA (Ground Controlled Approach) radar unit. There he began to produce the first of many science-fiction stories. In 1949–50 he was an assistant editor of Science Abstracts at the Institution of Electrical Engineers.
    As a result of his two interests, he realized during the Second World War that an artificial earth satellite in an equatorial orbital with a radius of 35,000 km (22,000 miles) would appear to be stationary, and that three such geo-stationary, or synchronous, satellites could be used for worldwide broadcast or communications. He described these ideas in a paper published in Wireless World in 1945. Initially there was little response, but within a few years the idea was taken up by the US National Aeronautics and Space Administration and in 1965 the first synchronous satellite, Early Bird, was launched into orbit.
    In the 1950s he moved to Ceylon (now Sri Lanka) to pursue an interest in underwater exploration, but he continued to write science fiction, being known in particular for his contribution to the making of the classic Stanley Kubrick science-fiction film 2001: A Space Odyssey, based on his book of the same title.
    [br]
    Principal Honours and Distinctions
    Clarke received many honours for both his scientific and science-fiction writings. For his satellite communication ideas his awards include the Franklin Institute Gold Medal 1963 and Honorary Fellowship of the American Institute of Aeronautics and Astronautics 1976. For his science-fiction writing he received the UNESCO Kalinga Prize (1961) and many others. In 1979 he became Chancellor of Moratuwa University in Sri Lanka and in 1980 Vikran Scrabhai Professor at the Physical Research Laboratory of the University of Ahmedabad.

    [br]
    b. 3 March 1847 Edinburgh, Scotland
    d. 3 August 1922 Beinn Bhreagh, Baddeck, Cape Breton Island, Nova Scotia, Canada
    [br]
    Scottish/American inventor of the telephone.
    [br]
    Bell's grandfather was a professor of elocution in London and his father an authority on the physiology of the voice and on elocution; Bell was to follow in their footsteps. He was educated in Edinburgh, leaving school at 13. In 1863 he went to Elgin, Morayshire, as a pupil teacher in elocution, with a year's break to study at Edinburgh University; it was in 1865, while still in Elgin, that he first conceived the idea of the electrical transmission of speech. He went as a master to Somersetshire College, Bath (now in Avon), and in 1867 he moved to London to assist his father, who had taken up the grandfather's work in elocution. In the same year, he matriculated at London University, studying anatomy and physiology, and also began teaching the deaf. He continued to pursue the studies that were to lead to the invention of the telephone. At this time he read Helmholtz's The Sensations of Tone, an important work on the theory of sound that was to exert a considerable influence on him.
    In 1870 he accompanied his parents when they emigrated to Canada. His work for the deaf gained fame in both Canada and the USA, and in 1873 he was apponted professor of vocal physiology and the mechanics of speech at Boston University, Massachusetts. There, he continued to work on his theory that sound wave vibrations could be converted into a fluctuating electric current, be sent along a wire and then be converted back into sound waves by means of a receiver. He approached the problem from the background of the theory of sound and voice production rather than from that of electrical science, and by 1875 he had succeeded in constructing a rough model. On 7 March 1876 Bell spoke the famous command to his assistant, "Mr Watson, come here, I want you": this was the first time a human voice had been transmitted along a wire. Only three days earlier, Bell's first patent for the telephone had been granted. Almost simultaneously, but quite independently, Elisha Gray had achieved a similar result. After a period of litigation, the US Supreme Court awarded Bell priority, although Gray's device was technically superior.
    In 1877, three years after becoming a naturalized US citizen, Bell married the deaf daughter of his first backer. In August of that year, they travelled to Europe to combine a honeymoon with promotion of the telephone. Bell's patent was possibly the most valuable ever issued, for it gave birth to what later became the world's largest private service organization, the Bell Telephone Company.
    Bell had other scientific and technological interests: he made improvements in telegraphy and in Edison's gramophone, and he also developed a keen interest in aeronautics, working on Curtiss's flying machine. Bell founded the celebrated periodical Science.

    After obtaining his AB degree from De Pere University, Wisconsin (1937), and his AM and PhD from the University of Michigan (1938 and 1941, respectively), Burks carried out research at the Moore School of Engineering, University of Pennsylvania, during the Second World War, and at the same time taught philosophy in another department. There, with Herman Goldstine, he was involved in the construction of ENIAC (the Electronic Numerical Integrator and Computer).
    In 1946 he took a post as Assistant Professor of Engineering at Michigan University, and subsequently became Associate Professor (1948) and Full Professor (1954). Between 1946 and 1948 he was also associated with the computer activities of John von Neumann at the Institute of Advanced Studies, Princeton, and was involved in the development of the Whirlwind I computer (the first stored-program computer) by Jay Forrester at the Massachusetts Institute of Technology. From 1948 until 1954 he was a consultant for the Burroughs Corporation and also contributed to the Oak Ridge computer ORACLE. He was Chairman of the Michigan University Department of Communications Science in 1967–71 and at various times was Visiting Professor at Harvard University and the universities of Illinois and Stanford. In 1975 he became Editor of the Journal of Computer and System Sciences.

    b. 9 November 1878 Auckland Province, New Zealand
    d. 24 March 1961 Troy, New York, USA
    [br]
    New Zealand/American technologist and academic who was a pioneer in the production of metallic titanium.
    [br]
    Hunter arrived in England in 1902, the seventh in the succession of New Zealand students nominated for the 1851 Exhibition science research scholarships (the third, in 1894, having been Ernest Rutherford). He intended to study the metallurgy of tellurides at the Royal School of Mines, but owing to the death of the professor concerned, he went instead to University College London, where his research over two years involved the molecular aggregation of liquified gases. In 1904–5 he spent a third year in Göttingen, Paris and Karlsruhe. Hunter then moved to the USA, beginning work in 1906 with the General Electric Company in Schenectady. His experience with titanium came as part of a programme to try to discover satisfactory lamp-filament materials. He and his colleagues achieved more success in producing moderately pure titanium than previous workers had done, but found the metal's melting temperature inadequate. However, his research formed the basis for the "Hunter sodium process", a modern method for producing commercial quantities of titanium. In 1908 he was appointed Assistant Professor of Electrochemistry and Physics at Rensselaer Polytechnic Institute in Troy, New York, where he was to remain until his retirement in 1949 as Dean Emeritus. In the 1930s he founded and headed the Institute's Department of Metallurgical Engineering. As a consultant, he was associated with the development of Invar, Managanin and Constantan alloys.

    [br]
    b. 1 August 1817 Hull, England
    d. 23 December 1901 England
    [br]
    English chemist who co-established the reputation of Rothampsted Experimental Station as at the forefront of agricultural research.
    [br]
    Joseph Gilbert was the son of a congregational minister. His schooling was interrupted by the loss of an eye as the result of a shooting accident, but despite this setback he entered Glasgow University to study analytical chemistry, and then went to University College, London, where he was a fellow student of John Bennet Lawes. During his studies he visited Giessen, Germany, and worked in the laboratory of Justus von Liebig. In 1843, at the age of 26, he was hired as an assistant by Lawes, who was 29 at that time; an unbroken friendship and collaboration existed between the two until Lawes died in 1900. They began a series of experiments on grain production and grew plots under different applications of nitrogen, with control plots that received none at all. Much of the work at Rothampsted was on the nitrogen requirements of plants and how this element became available to them. The grain grown in these experiments was analyzed to determine whether nitrogen input affected grain quality. Gilbert was a methodical worker who by the time of his death had collected together some 50,000 carefully stored and recorded samples.

    b. 5 July 1820 Edinburgh, Scotland
    d. 1872
    [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.

  • 17 Langley, Samuel Pierpont

    SUBJECT AREA: Aerospace
    [br]
    b. 22 August 1834 Roxbury, Massachusetts, USA
    d. 27 February 1906 Aiken, South Carolina, USA
    [br]
    American scientist who built an unsuccessful aeroplane in 1903, just before the success of the Wright brothers.
    [br]
    Professor Langley was a distinguished mathematician and astronomer who became Secretary of the Smithsonian Institution (US National Museum) in 1887. He was also interested in aviation and embarked on a programme of experiments with a whirling arm to test wings and with a series of free-flying models. In 1896 one of his steam-powered models made a flight of 4,199 ft (1,280 m): this led to a grant from the Government to subsidize the construction of a manned aeroplane. Langley commissioned Stephen M. Balzer, an automobile engine designer, to build a lightweight aero-engine and appointed his assistant, Charles M.Manly, to oversee the project. After many variations, including rotary and radical designs, two versions of the Balzer-Manly engine were produced, one quarter size and one full size. In August 1903 the small engine powered a model which thus became the first petrol-engined aeroplane to fly. Langley designed his full-size aeroplane (which he called an Aerodrome) with tandem wings and a cruciform tail unit. The Balzer-Manly engine drove two pusher propellers. Manly was to be the pilot as Langley was now almost 70 years old. Most early aviators tested their machines by making tentative hops, but Langley decided to launch his Aerodrome by catapult from the roof of a houseboat on the Potomac river. Two attempts were made and on both occasions the Aerodrome crashed into the river: catapult problems and perhaps a structural weakness were to blame. The second crash occurred on 8 December 1903 and it is ironic that the Wright brothers, with limited funds and no Government support, successfully achieved a manned flight just nine days later. Langley was heartbroken. After his death there followed a strange affair in 1914 when Glenn Curtiss took Langley's Aerodrome, modified it, and tried to prove that but for the faulty catapult it would have flown before the Wrights' Flyer. A brief flight was made with floats instead of the catapult, and it flew rather better after more extensive modifications and a new engine.

  • 18 Lodge, Sir Oliver Joseph

    [br]
    b. 12 June 1851 Penkhull, Staffordshire, England
    d. 22 August 1940 Lake, near Salisbury, Wiltshire, England
    [br]
    English physicist who perfected Branly's coherer; said to have given the first public demonstration of wireless telegraphy.
    [br]
    At the age of 8 Lodge entered Newport Grammar School, and in 1863–5 received private education at Coombs in Suffolk. He then returned to Staffordshire, where he assisted his father in the potteries by working as a book-keeper. Whilst staying with an aunt in London in 1866–7, he attended scientific lectures and became interested in physics. As a result of this and of reading copies of English Mechanic magazine, when he was back home in Hanley he began to do experiments and attended the Wedgewood Institute. Returning to London c. 1870, he studied initially at the Royal College of Science and then, from 1874, at University College, London (UCL), at the same time attending lectures at the Royal Institution.
    In 1875 he obtained his BSc, read a paper to the British Association on "Nodes and loops in chemical formulae" and became a physics demonstrator at UCL. The following year he was appointed a physics lecturer at Bedford College, completing his DSc in 1877. Three years later he became Assistant Professor of Mathematics at UCL, but in 1881, after only two years, he accepted the Chair of Experimental Physics at the new University College of Liverpool. There began a period of fruitful studies of electricity and radio transmission and reception, including development of the lightning conductor, discovery of the "coherent" effect of sparks and improvement of Branly's coherer, and, in 1894, what is said to be the first public demonstration of the transmission and reception (using a coherer) of wireless telegraphy, from Lewis's department store to the clock tower of Liverpool University's Victoria Building. On 10 May 1897 he filed a patent for selective tuning by self-in-ductance; this was before Marconi's first patent was actually published and its priority was subsequently upheld.
    In 1900 he became the first Principal of the new University of Birmingham, where he remained until his retirement in 1919. In his later years he was increasingly interested in psychical research.
