    b. 8 January 1891 Oranienburg, Berlin, Germany
    d. 8 February 1957 Heidelberg, Germany
    [br]
    German nuclear scientist.
    [br]
    Bothe studied under Max Planck at the University of Berlin, gaining his doctorate in 1914. After military service during the First World War, he resumed his investigations into nuclear physics and achieved a breakthrough in 1929 when he developed a method of studying cosmic radiation by placing one Geiger counter on top of another. From this he evolved the means of high-speed counting known as "coincidence counting". The following year, in conjunction with Hans Becker, Bothe made a Further stride forward when they identified a very penetrative neutral particle by bombarding beryllium with alpha particles; this was a significant advance towards creating nuclear energy in that the neutral particle was what Chadwick later identified as the neutron.
    In 1934 Bothe's achievements were recognized by his appointment as Director of the Max Planck Institute for Medical Research, although this was after Planck himself had been deposed because of his Jewish sympathies. Bothe did, however, become primarily involved in Germany's pursuit of the atomic bomb and in 1944 constructed Germany's first cyclotron for accelerating nuclear particles. By that time Germany was faced with military defeat and Bothe was not able to develop his ideas further. Even so, for his work in the field of cosmic radiation Bothe shared the 1954 Nobel Prize for Physics with the naturalized Briton (formerly German) Max Born, whose subject was statistical mechanics.

    b. 13 February 1834 Poznan, Poland
    d. 11 October 1911 Dresden, Germany
    [br]
    German dyestuffi chemist.
    [br]
    Caro received vocational training as a dyer at the Gewerbeinstitut in Berlin from 1852, at the same time attending chemistry lectures at the university there. In 1855 he was hired as a colourist by a firm of calico printers in Mulheim an der Ruhr, where he was able to demonstrate the value of scientific training in solving practical problems. Two years later, the year after Perkin's discovery of aniline dyes, he was sent to England in order to learn the latest dyeing techniques. He took up a post an analytical chemist with the chemical firm Roberts, Dale \& Co. in Manchester; after finding a better way of synthesizing Perkin's mauve, he became a partner in the business. Caro was able to enlarge both his engineering experience and his chemical knowledge there, particularly by studying Hofmann's researches on the aniline dyes. He made several discoveries, including induline, Bismark brown and Martius yellow.
    Like other German chemists, however, he found greater opportunities opening up in Germany, and in 1866 he returned to take up a post in Bunsen's laboratory in Heidelberg. In 1868 Caro obtained the important directorship of Badische Anilin-Soda- Fabrik (BASF), the first true industrial research organization and leading centre of dyestuffs research. A steady stream of commercial successes followed. In 1869, after Graebe and Liebermann had showed him their laboratory synthesis of the red dye alizarin, Caro went on to develop a cheaper and commercially viable method. During the 1870s he collaborated with Adolf von Baeyer to make methylene blue and related dyes, and then went on to the azo dyes. His work on indigo was important, but was not crowned with commercial success; that came in 1897 when his successor at BASF discovered a suitable process for producing indigo on a commercial scale. Caro had resigned his post in 1889, by which time he had made notable contributions to German supremacy in the fast-developing dyestuffs industry.

    SUBJECT AREA: Metallurgy
    [br]
    b. 31 December 1888 Thizy, Rhône, France
    d. 15 August 1960 Fontenoy-aux-Roses, France
    [br]
    French metallurgist, inventor of the alloys Elinvar and Platinite and of the method of strengthening nickel-chromium alloys by a precipitate ofNi3Al which provided the basis of all later super-alloy development.
    [br]
    Soon after graduating from the Ecole des Mines at St-Etienne in 1910, Chevenard joined the Société de Commentry Fourchambault et Decazeville at their steelworks at Imphy, where he remained for the whole of his career. Imphy had for some years specialized in the production of nickel steels. From this venture emerged the first austenitic nickel-chromium steel, containing 6 per cent chromium and 22–4 per cent nickel and produced commercially in 1895. Most of the alloys required by Guillaume in his search for the low-expansion alloy Invar were made at Imphy. At the Imphy Research Laboratory, established in 1911, Chevenard conducted research into the development of specialized nickel-based alloys. His first success followed from an observation that some of the ferro-nickels were free from the low-temperature brittleness exhibited by conventional steels. To satisfy the technical requirements of Georges Claude, the French cryogenic pioneer, Chevenard was then able in 1912 to develop an alloy containing 55–60 per cent nickel, 1–3 per cent manganese and 0.2–0.4 per cent carbon. This was ductile down to −190°C, at which temperature carbon steel was very brittle.
    By 1916 Elinvar, a nickel-iron-chromium alloy with an elastic modulus that did not vary appreciably with changes in ambient temperature, had been identified. This found extensive use in horology and instrument manufacture, and even for the production of high-quality tuning forks. Another very popular alloy was Platinite, which had the same coefficient of thermal expansion as platinum and soda glass. It was used in considerable quantities by incandescent-lamp manufacturers for lead-in wires. Other materials developed by Chevenard at this stage to satisfy the requirements of the electrical industry included resistance alloys, base-metal thermocouple combinations, magnetically soft high-permeability alloys, and nickel-aluminium permanent magnet steels of very high coercivity which greatly improved the power and reliability of car magnetos. Thermostatic bimetals of all varieties soon became an important branch of manufacture at Imphy.
    During the remainder of his career at Imphy, Chevenard brilliantly elaborated the work on nickel-chromium-tungsten alloys to make stronger pressure vessels for the Haber and other chemical processes. Another famous alloy that he developed, ATV, contained 35 per cent nickel and 11 per cent chromium and was free from the problem of stress-induced cracking in steam that had hitherto inhibited the development of high-power steam turbines. Between 1912 and 1917, Chevenard recognized the harmful effects of traces of carbon on this type of alloy, and in the immediate postwar years he found efficient methods of scavenging the residual carbon by controlled additions of reactive metals. This led to the development of a range of stabilized austenitic stainless steels which were free from the problems of intercrystalline corrosion and weld decay that then caused so much difficulty to the manufacturers of chemical plant.
    Chevenard soon concluded that only the nickel-chromium system could provide a satisfactory basis for the subsequent development of high-temperature alloys. The first published reference to the strengthening of such materials by additions of aluminium and/or titanium occurs in his UK patent of 1929. This strengthening approach was adopted in the later wartime development in Britain of the Nimonic series of alloys, all of which depended for their high-temperature strength upon the precipitated compound Ni3Al.
    In 1936 he was studying the effect of what is now known as "thermal fatigue", which contributes to the eventual failure of both gas and steam turbines. He then published details of equipment for assessing the susceptibility of nickel-chromium alloys to this type of breakdown by a process of repeated quenching. Around this time he began to make systematic use of the thermo-gravimetrie balance for high-temperature oxidation studies.

    SUBJECT AREA: Metallurgy
    [br]
    d. 1693
    [br]
    English entrepreneur responsible, with others, for attempts to introduce coal-fired smelting of lead and, later, of copper.
    [br]
    Clerke, from Launde Abbey in Leicestershire, was involved in early experiments to smelt lead using coal fuel, which was believed to have been located on the Leicestershire-Derbyshire border. Concurrently, Lord Grandison was financing experiments at Bristol for similar purposes, causing the downfall of an earlier unsuccessful patented method before securing his own patent in 1678. In that same year Clerke took over management of the Bristol works, claiming the ability to secure financial return from Grandison's methods. Financial success proved elusive, although the technical problems of adapting the reverberatory furnace to coal fuel appear to have been solved when Clerke was found to have established another lead works nearby on his own account. He was forced to cease work on lead in 1684 in respect of Grandison's patent rights. Clerke then turned to investigations into the coal-fired smelting of other metals and started to smelt copper in coal-fired reverberatory furnaces. By 1688–9 small supplied of merchantable copper were offered for sale in London in order to pay his workers, possibly because of further financial troubles. The practical success of his smelting innovation is widely acknowledged to have been the responsibility of John Coster and, to a smaller extent, Gabriel Wayne, both of whom left Clerke and set up separate works elsewhere. Clerke's son Talbot took over administration of his father's works, which declined still further and closed c. 1693, at about the time of Sir Clement's death. Both Coster and Wayne continued to develop smelting techniques, establishing a new British industry in the smelting of copper with coal.

    b. 11 March 1818 St Thomas, Virgin Islands
    d. 1 July 1881 Boulogne-sur-Seine, France
    [br]
    French chemist and metallurgist, pioneer in the large-scale production of aluminium and other light metals.
    [br]
    Deville was the son of a prosperous shipowner with diplomatic duties in the Virgin Islands. With his elder brother Charles, who later became a distinguished physicist, he was sent to Paris to be educated. He took his degree in medicine in 1843, but before that he had shown an interest in chemistry, due particularly to the lectures of Thenard. Two years later, with Thenard's influence, he was appointed Professor of Chemistry at Besançon. In 1851 he was able to return to Paris as Professor at the Ecole Normale Supérieure. He remained there for the rest of his working life, greatly improving the standard of teaching, and his laboratory became one of the great research centres of Europe. His first chemical work had been in organic chemistry, but he then turned to inorganic chemistry, specifically to improve methods of producing the new and little-known metal aluminium. Essentially, the process consisted of forming sodium aluminium trichloride and reducing it with sodium to metallic aluminium. He obtained sodium in sufficient quantity by reducing sodium carbonate with carbon. In 1855 he exhibited specimens of the metal at the Paris Exhibition, and the same year Napoleon III asked to see them, with a view to using it for breastplates for the Army and for spoons and forks for State banquets. With the resulting government support, he set up a pilot plant at Jarvel to develop the process, and then set up a small company, the Société d'Aluminium at Nan terre. This raised the output of this attractive and useful metal, so it could be used more widely than for the jewellery to which it had hitherto been restricted. Large-scale applications, however, had to await the electrolytic process that began to supersede Deville's in the 1890s. Deville extended his sodium reduction method to produce silicon, boron and the light metals magnesium and titanium. His investigations into the metallurgy of platinum revolutionized the industry and led in 1872 to his being asked to make the platinum-iridium (90–10) alloy for the standard kilogram and metre. Deville later carried out important work in high-temperature chemistry. He grieved much at the death of his brother Charles in 1876, and his retirement was forced by declining health in 1880; he did not survive for long.

    [br]
    French civil engineer who is generally recognized as the originator of pre-stressed reinforced concrete.
    [br]
    Eugène Freyssinet was an army engineer during the First World War who pioneered pre-stressed reinforced concrete and experimented with building concrete bridges. After 1918 he formed his own company to develop his ideas. He investigated the possibilities of very high-strength concrete, and in so doing studied shrinkage and creep. He combined high-quality concrete with highly stressed, stretched steel to give top quality results. His work in 1926 on Plougastel Bridge, at that time the longest reinforced concrete bridge, is a notable example of his use of this technique. In 1916 Freyssinet had built his famous airship hangars at Orly, which were destroyed in the Second World War; the hangars were roofed in parabolic sections to a height of about 200 ft. In 1934 he succeeded in saving the Ocean Terminal at Le Havre from sinking into the mud and being covered by the sea by using his pre-stressing techniques. By 1938 he had developed a superior method of pre-stressing with steel which led to widespread adoption of his methods.

    While in business as a goldsmith and jeweller, he came across the earliest known attempt to make stereotypes, that by Van der Meys of Leiden in the sixteenth century. He soldered types to the bases of a bed of type, but the process proved too expensive to be adopted. Ged took out a patent of privilege in 1725 to develop Mey's method, agreeing with a printer that if they could make casts of made-up pages of type they "would make a fortune". After many experiments to find a suitable metal, he arrived at an alloy similar to type metal. However, Ged's efforts to promote his stereotypes were blocked by the indifference of the printers and the opposition of the compositors. He tried his luck in London but failed again for much the same reason as in Edinburgh. Thither he returned, but he died in poverty.

    b. 18 May 1850 London, England
    d. 2 February 1925 Torquay, Devon, England
    [br]
    English physicist who correctly predicted the existence of the ionosphere and its ability to reflect radio waves.
    [br]
    Brought up in poor, almost Dickensian, circumstances, at the age of 13 years Heaviside, a nephew by marriage of Sir Charles Wheatstone, went to Camden House Grammar School. There he won a medal for science, but he was forced to leave because his parents could not afford the fees. After a year of private study, he began his working life in Newcastle in 1870 as a telegraph operator for an Anglo-Dutch cable company, but he had to give up after only four years because of increasing deafness. He therefore proceeded to spend his time studying theoretical aspects of electrical transmission and communication, and moved to Devon with his parents in 1889. Because the operation of many electrical circuits involves transient phenomena, he found it necessary to develop what he called operational calculus (which was essentially a form of the Laplace transform calculus) in order to determine the response to sudden voltage and current changes. In 1893 he suggested that the distortion that occurred on long-distance telephone lines could be reduced by adding loading coils at regular intervals, thus creating a matched-transmission line. Between 1893 and 1912 he produced a series of writings on electromagnetic theory, in one of which, anticipating a conclusion of Einstein's special theory of relativity, he put forward the idea that the mass of an electric charge increases with its velocity. When it was found that despite the curvature of the earth it was possible to communicate over very great distances using radio signals in the so-called "short" wavebands, Heaviside suggested the presence of a conducting layer in the ionosphere that reflected the waves back to earth. Since a similar suggestion had been made almost at the same time by Arthur Kennelly of Harvard, this layer became known as the Kennelly-Heaviside layer.

    d. 8 March 1946 Birmingham, England
    [br]
    English designer and builder of the first all-British motor car.
    [br]
    The fourth of eight children of an architect, he spent his childhood in Hove and attended a private preparatory school, from where, aged 14, he went to the Hartley Institution (the forerunner of Southampton University). He was then granted a scholarship to the Royal College of Science, South Kensington, and also studied practical engineering at Finsbury Technical College, London. He worked first for a draughtsman and pseudo-patent agent, and was then appointed Assistant Works Manager of the Forward Gas Engine Company of Birmingham, with sixty men and a salary of £1 per week. He was then aged 21. His younger brother, George, was apprenticed to the same company. In 1889 and 1890 he invented a pendulum governor and an engine starter which earned him royalties. He built a flat-bottomed river craft with a stern paddle-wheel and a vertical single-cylinder engine with a wick carburettor of his own design. From 1892 he performed a number of garden experiments on model gliders relating to problems of lift and drag, which led him to postulate vortices from the wingtips trailing behind, much of his work lying behind the theory of modern aerodynamics. The need to develop a light engine for aircraft led him to car design.
    In February 1896 his first experimental car took the road. It had a torsionally rigid chassis, a perfectly balanced and almost noiseless engine, dynamically stable steering, epicyclic gear for low speed and reverse with direct drive for high speed. It turned out to be underpowered and was therefore redesigned. Two years later an 8 hp, two-cylinder flat twin appeared which retained the principle of balancing by reverse rotation, had new Lanchester valve-gear and a new method of ignition based on a magneto generator. For the first time a worm and wheel replaced chain-drive or bevel-gear transmission. Lanchester also designed the machinery to make it. The car was capable of about 18 mph (29 km/h): future cars of his travelled at twice that speed. From 1899 to 1904 cars were produced for sale by the Lanchester Engine Company, which was formed in 1898. The company had to make every component except the tyres. Lanchester gave up the managership but remained as Chief Designer, and he remained in this post until 1914.
    In 1907–8 his two-volume treatise Aerial Flight was published; it included consideration of skin friction, boundary-layer theory and the theory of stability. In 1909 he was appointed to the Government's Committee for Aeronautics and also became a consultant to the Daimler Company. At the age of 51 he married Dorothea Cooper. He remained a consultant to Daimler and worked also for Wolseley and Beardmore until 1929 when he started Lanchester Laboratories, working on sound reproduction. He also wrote books on relativity and on the theory of dimensions.

    b. 26 July 1919 Brixton, London, England
    [br]
    English biologist and philosopher, inventor of the microwave oven and electron capture detector.
    [br]
    Lovelock was brought up in Brixton in modest circumstances. At the age of 4 he was given a toy electrical set, which first turned his attention towards the study of science. From the Strand School, Brixton, he went on to the universities of Manchester and London, and after graduating in science, in 1941 he joined the National Institute for Medical Research, Mill Hill, as a staff scientist, remaining there for twenty years. During the early 1950s, he and his colleagues were engaged in research into freezing live animals and bringing them back to life by heating: Lovelock was struck by the intense pain this process caused the animals, and he sought a more humane method. He tried diathermy or internal heating through the effect of a continuous wave magnetron borrowed from the Navy. He found that the animals were brought back to life painlessly, and impressed with his success he tried baking a potato for his lunch in the apparatus and found that it cooked amazingly quickly compared with the one hour normally needed in an ordinary oven. Lovelock had invented the microwave oven, but its commercial possibilities were not at first realized.
    In the late 1950s he invented the electron capture detector, which proved to be more sensitive than any other analytical equipment in detecting and measuring toxic substances. The apparatus therefore had obvious uses in testing the quality of the environment and so offered a tremendous boost to the "green" movement. In 1961 he was invited to joint the US National Aeronautics and Space Administration (NASA) to employ the apparatus in an attempt to detect life in space.
    In the early 1970s Lovelock relinquished his biological work in order to devote his attention to philosophical matters, specifically to develop his theory of the Universe, now widely celebrated as the "Gaia theory". In this controversial theory, Lovelock regards our planet and all its living beings, including humans, as a single living organism.

Three years later, in 1872, he was appointed Blast-furnace Manager at the pioneering Siemens Steel Company's works at Landore, near Swansea in South Wales. Using Spanish ore, he produced the manganese-rich iron (spiegeleisen) required as an additive to make satisfactory steel. Riley was promoted in 1874 to be General Manager at Landore, and he worked with William Siemens to develop the use of the latter's regenerative furnace for the production of open-hearth steel. He persuaded Welsh makers of tin plate to use sheets rolled from lowcarbon (mild) steel instead of from charcoal iron and, partly by publishing some test results, he was instrumental in influencing the Admiralty to build two naval vessels of mild steel, the Mercury and the Iris.
    In 1878 Riley moved north on his appointment as General Manager of the Steel Company of Scotland, a firm closely associated with Charles Tennant that was formed in 1872 to make steel by the Siemens process. Already by 1878, fourteen Siemens melting furnaces had been erected, and in that year 42,000 long tons of ingots were produced at the company's Hallside (Newton) Works, situated 8 km (5 miles) south-east of Glasgow. Under Riley's leadership, steelmaking in open-hearth furnaces was initiated at a second plant situated at Blochairn. Plates and sections for all aspects of shipbuilding, including boilers, formed the main products; the company also supplied the greater part of the steel for the Forth (Railway) Bridge. Riley was associated with technical modifications which improved the performance of steelmaking furnaces using Siemens's principles. He built a gasfired cupola for melting pig-iron, and constructed the first British "universal" plate mill using three-high rolls (Lauth mill).
    At the request of French interests, Riley investigated the properties of steels containing various proportions of nickel; the report that he read before the Iron and Steel Institute in 1889 successfully brought to the notice of potential users the greatly enhanced strength that nickel could impart and its ability to yield alloys possessing substantially lower corrodibility.
    The Steel Company of Scotland paid dividends in the years to 1890, but then came a lean period. In 1895, at the age of 54, Riley moved once more to another employer, becoming General Manager of the Glasgow Iron and Steel Company, which had just laid out a new steelmaking plant at Wishaw, 25 km (15 miles) south-east of Glasgow, where it already had blast furnaces. Still the technical innovator, in 1900 Riley presented an account of his experiences in introducing molten blast-furnace metal as feed for the open-hearth steel furnaces. In the early 1890s it was largely through Riley's efforts that a West of Scotland Board of Conciliation and Arbitration for the Manufactured Steel Trade came into being; he was its first Chairman and then its President.
    In 1899 James Riley resigned from his Scottish employment to move back to his native Yorkshire, where he became his own master by acquiring the small Richmond Ironworks situated at Stockton-on-Tees. Although Riley's 1900 account to the Iron and Steel Institute was the last of the many of which he was author, he continued to contribute to the discussion of papers written by others.

    b. 25 July 1857 Milford, Connecticut, USA
    d. 25 October 1934 New York, USA
    [br]
    American electrical engineer and inventor, a leading innovator in electric propulsion systems for urban transport.
    [br]
    Graduating from the United States Naval Academy, Annapolis, in 1878, Sprague served at sea and with various shore establishments. In 1883 he resigned from the Navy and obtained employment with the Edison Company; but being convinced that the use of electricity for motive power was as important as that for illumination, in 1884 he founded the Sprague Electric Railway and Motor Company. Sprague began to develop reliable and efficient motors in large sizes, marketing 15 hp (11 kW) examples by 1885. He devised the method of collecting current by using a wooden, spring-loaded rod to press a roller against the underside of an overhead wire. The installation by Sprague in 1888 of a street tramway on a large scale in Richmond, Virginia, was to become the prototype of the universally adopted trolley system with overhead conductor and the beginning of commercial electric traction. Following the success of the Richmond tramway the company equipped sixty-seven other railways before its merger with Edison General Electric in 1890. The Sprague traction motor supported on the axle of electric streetcars and flexibly mounted to the bogie set a pattern that was widely adopted for many years.
    Encouraged by successful experiments with multiple-sheave electric elevators, the Sprague Elevator Company was formed and installed the first set of high-speed passenger cars in 1893–4. These effectively displaced hydraulic elevators in larger buildings. From experience with control systems for these, he developed his system of multiple-unit control for electric trains, which other engineers had considered impracticable. In Sprague's system, a master controller situated in the driver's cab operated electrically at a distance the contactors and reversers which controlled the motors distributed down the train. After years of experiment, Sprague's multiple-unit control was put into use for the first time in 1898 by the Chicago South Side Elevated Railway: within fifteen years multiple-unit operation was used worldwide.

  • 56 Stephenson, Robert

    [br]
    b. 16 October 1803 Willington Quay, Northumberland, England
    d. 12 October 1859 London, England
    [br]
    English engineer who built the locomotive Rocket and constructed many important early trunk railways.
    [br]
    Robert Stephenson's father was George Stephenson, who ensured that his son was educated to obtain the theoretical knowledge he lacked himself. In 1821 Robert Stephenson assisted his father in his survey of the Stockton \& Darlington Railway and in 1822 he assisted William James in the first survey of the Liverpool \& Manchester Railway. He then went to Edinburgh University for six months, and the following year Robert Stephenson \& Co. was named after him as Managing Partner when it was formed by himself, his father and others. The firm was to build stationary engines, locomotives and railway rolling stock; in its early years it also built paper-making machinery and did general engineering.
    In 1824, however, Robert Stephenson accepted, perhaps in reaction to an excess of parental control, an invitation by a group of London speculators called the Colombian Mining Association to lead an expedition to South America to use steam power to reopen gold and silver mines. He subsequently visited North America before returning to England in 1827 to rejoin his father as an equal and again take charge of Robert Stephenson \& Co. There he set about altering the design of steam locomotives to improve both their riding and their steam-generating capacity. Lancashire Witch, completed in July 1828, was the first locomotive mounted on steel springs and had twin furnace tubes through the boiler to produce a large heating surface. Later that year Robert Stephenson \& Co. supplied the Stockton \& Darlington Railway with a wagon, mounted for the first time on springs and with outside bearings. It was to be the prototype of the standard British railway wagon. Between April and September 1829 Robert Stephenson built, not without difficulty, a multi-tubular boiler, as suggested by Henry Booth to George Stephenson, and incorporated it into the locomotive Rocket which the three men entered in the Liverpool \& Manchester Railway's Rainhill Trials in October. Rocket, was outstandingly successful and demonstrated that the long-distance steam railway was practicable.
    Robert Stephenson continued to develop the locomotive. Northumbrian, built in 1830, had for the first time, a smokebox at the front of the boiler and also the firebox built integrally with the rear of the boiler. Then in Planet, built later the same year, he adopted a layout for the working parts used earlier by steam road-coach pioneer Goldsworthy Gurney, placing the cylinders, for the first time, in a nearly horizontal position beneath the smokebox, with the connecting rods driving a cranked axle. He had evolved the definitive form for the steam locomotive.
    Also in 1830, Robert Stephenson surveyed the London \& Birmingham Railway, which was authorized by Act of Parliament in 1833. Stephenson became Engineer for construction of the 112-mile (180 km) railway, probably at that date the greatest task ever undertaken in of civil engineering. In this he was greatly assisted by G.P.Bidder, who as a child prodigy had been known as "The Calculating Boy", and the two men were to be associated in many subsequent projects. On the London \& Birmingham Railway there were long and deep cuttings to be excavated and difficult tunnels to be bored, notoriously at Kilsby. The line was opened in 1838.
    In 1837 Stephenson provided facilities for W.F. Cooke to make an experimental electrictelegraph installation at London Euston. The directors of the London \& Birmingham Railway company, however, did not accept his recommendation that they should adopt the electric telegraph and it was left to I.K. Brunel to instigate the first permanent installation, alongside the Great Western Railway. After Cooke formed the Electric Telegraph Company, Stephenson became a shareholder and was Chairman during 1857–8.
    Earlier, in the 1830s, Robert Stephenson assisted his father in advising on railways in Belgium and came to be increasingly in demand as a consultant. In 1840, however, he was almost ruined financially as a result of the collapse of the Stanhope \& Tyne Rail Road; in return for acting as Engineer-in-Chief he had unwisely accepted shares, with unlimited liability, instead of a fee.
    During the late 1840s Stephenson's greatest achievements were the design and construction of four great bridges, as part of railways for which he was responsible. The High Level Bridge over the Tyne at Newcastle and the Royal Border Bridge over the Tweed at Berwick were the links needed to complete the East Coast Route from London to Scotland. For the Chester \& Holyhead Railway to cross the Menai Strait, a bridge with spans as long-as 460 ft (140 m) was needed: Stephenson designed them as wrought-iron tubes of rectangular cross-section, through which the trains would pass, and eventually joined the spans together into a tube 1,511 ft (460 m) long from shore to shore. Extensive testing was done beforehand by shipbuilder William Fairbairn to prove the method, and as a preliminary it was first used for a 400 ft (122 m) span bridge at Conway.
    In 1847 Robert Stephenson was elected MP for Whitby, a position he held until his death, and he was one of the exhibition commissioners for the Great Exhibition of 1851. In the early 1850s he was Engineer-in-Chief for the Norwegian Trunk Railway, the first railway in Norway, and he also built the Alexandria \& Cairo Railway, the first railway in Africa. This included two tubular bridges with the railway running on top of the tubes. The railway was extended to Suez in 1858 and for several years provided a link in the route from Britain to India, until superseded by the Suez Canal, which Stephenson had opposed in Parliament. The greatest of all his tubular bridges was the Victoria Bridge across the River St Lawrence at Montreal: after inspecting the site in 1852 he was appointed Engineer-in-Chief for the bridge, which was 1 1/2 miles (2 km) long and was designed in his London offices. Sadly he, like Brunel, died young from self-imposed overwork, before the bridge was completed in 1859.

  • 57 Tull, Jethro

    [br]
    b. 30 March 1674 Basildon, Essex, England
    d. February 1741 Hungerford, Berkshire, England
    [br]
    English farmer who developed and publicized a system of row crop husbandry.
    [br]
    Jethro Tull was born into an English landowning family. He was educated at St John's College, Oxford, but left without a degree at the age of 17. He then spent three years on the Grand Tour before returning to study law at Gray's Inn in London. After six years he was admitted to the Bar, but he never practised, moving instead to one of his father's farms near Oxford.
    Because of labour problems he chose to plant sainfoin (Onobrychis viciaefolia) as a forage crop because it required less frequent reseeding than grass. The seed itself was expensive and of poor fertility, so he began to experiment. He discovered that the depth of sowing as well as the planting rate influenced germination and the rate of growth, he found the optimum rate could be gained with one plant per ft2, a much lower density than could be achieved by broadcasting. His experiments created labour problems. He is traditionally and incorrectly credited with the invention of the seed drill, but he did develop and use a drill on his own farm to achieve the planting rate and depth he needed without having to rely on his workforce.
    In 1711 Tull became ill and went to France, having first sold his original farm and moved to "Properous", near Hungerford. In France he developed a husbandry technique that used a horse hoe to stir the soil between the rows of plants achieved with his drill. He incorrectly believed that his increased yields were the result of nutrients released from the soil by this method, whereas they were more likely to have been the result of a reduction in weed competition as a result of the repeated cultivation.
