  • 41 Hansom, Joseph Aloysius

    SUBJECT AREA: Land transport
    [br]
    b. 26 October 1803 York, England
    d. 29 June 1883 Fulham, London, England
    [br]
    English architect and inventor, originator of the Hansom cab.
    [br]
    In 1816 he was apprenticed to his father, who was a joiner. After a year his abilities in design and construction were so marked that it was decided that he would have more scope as an architect. He was accordingly apprenticed to a Mr Phillips in York, becoming a clerk to Phillips in 1820. While he served his time he also worked on his own account and taught at a night school. In 1825 he married Hannah Glover and settled in Halifax, where he became Assistant to another architect. In 1828 he became a partner of Edward Welch, with whom he built a number of churches in the north of England. He designed the Town Hall for Birmingham and was responsible for the constructional work until 1833, but he had to become bond because the builders caused him to become bankrupt. He was appointed Manager of the business affairs of Dempster Hemming of Caldicote Hall, which included the landed estates, banking and coal-mining. It was during this period that he designed the "Patent Safety Cab" named after him and popular in Victorian days. The safety element consisted in lowering the centre of gravity by the use of the cranked axle. Hansom sold his rights for £10,000 to a company proposing to exploit the patent, but he was never paid, for the company got into difficulties; Hansom became its temporary Manager in 1839 and put matters right, for which he was paid £300, all he ever made out of the Hansom Cab. In 1842 he brought out the first issue of The Builder, but lack of capital caused him to retire from the journal. He devoted himself from then on to domestic and ecclesiastical architecture, designing many churches, colleges, convents and schools all over Britain and even in Australia and South America. Of note is St Walburga's church, Preston, Lancashire, whose spire is 306 ft (93 m) high. At various times he was in partnership with his younger brother, his eldest son, and with E.W.Pugin with whom he had a disagreement. He was a Catholic and much of his work was for the Catholic Church.

  • 42 McAdam, John Loudon

    [br]
    b. 21 September 1756 Ayr, Ayrshire, Scotland
    d. 26 November 1836 Moffat, Dumfriesshire, Scotland
    [br]
    Scottish road builder, inventor of the macadam road surface.
    [br]
    McAdam was the son of one of the founder of the first bank in Ayr. As an infant, he nearly died in a fire which destroyed the family's house of Laywyne, in Carsphairn parish; the family then moved to Blairquhan, near Straiton. Thence he went to the parish school in Maybole, where he is said to have made a model section of a local road. In 1770, when his father died, he was sent to America where he was brought up by an uncle who was a merchant in New York. He stayed in America until the close of the revolution, becoming an agent for the sale of prizes and managing to amass a considerable fortune. He returned to Scotland where he settled at Sauchrie in Ayrshire. There he was a magistrate, Deputy-Lieutenant of the county and a road trustee, spending thirteen years there. In 1798 he moved to Falmouth in Devon, England, on his appointment as agent for revictualling of the Royal Navy in western ports.
    He continued the series of experiments started in Ayrshire on the construction of roads. From these he concluded that a road should be built on a raised foundation with drains formed on either side, and should be composed of a number of layers of hard stone broken into angular fragments of roughly cubical shape; the bottom layer would be larger rocks, with layers of progressively smaller rocks above, all bound together with fine gravel. This would become compacted and almost impermeable to water by the action of the traffic passing over it. In 1815 he was appointed Surveyor-General of Bristol's roads and put his theories to the test.
    In 1823 a Committee of the House of Commons was appointed to consider the use of "macadamized" roads in larger towns; McAdam gave evidence to this committee, and it voted to give him £10,000 for his past work. In 1827 he was appointed Surveyor-General of Roads and moved to Hoddesdon, Hertfordshire. From there he made yearly visits to Scotland and it was while returning from one of these that he died, at Moffat in the Scottish Borders. He had married twice, both times to American women; his first wife was the mother of all seven of his children.
    McAdam's method of road construction was much cheaper than that of Thomas Telford, and did much to ease travel and communications; it was therefore adopted by the majority of Turnpike Trusts in Britain, and the macadamization process quickly spread to other countries.

    SUBJECT AREA: Paper and printing
    [br]
    b. 6 November 1771 Prague, Bohemia (now Czech Republic)
    d. 26 February 1834 Munich, Germany
    [br]
    German inventor of lithography.
    [br]
    Soon after his birth, Senefelder's family moved to Mannheim, where his father, an actor, had obtained a position in the state theatre. He was educated there, until he gained a scholarship to the university of Ingolstadt. The young Senefelder wanted to follow his father on to the stage, but the latter insisted that he study law. He nevertheless found time to write short pieces for the theatre. One of these, when he was 18 years old, was an encouraging success. When his father died in 1791, he gave up his studies and took to a new life as poet and actor. However, the wandering life of a repertory actor palled after two years and he settled for the more comfortable pursuit of playwriting. He had some of his work printed, which acquainted him with the art of printing, but he fell out with his bookseller. He therefore resolved to carry out his own printing, but he could not afford the equipment of a conventional letterpress printer. He began to explore other ways of printing and so set out on the path that was to lead to an entirely new method.
    He tried writing in reverse on a copper plate with some acid-resisting material and etching the plate, to leave a relief image that could then be inked and printed. He knew that oily substances would resist acid, but it required many experiments to arrive at a composition of wax, soap and charcoal dust dissolved in rainwater. The plates wore down with repeated polishing, so he substituted stone plates. He continued to etch them and managed to make good prints with them, but he went on to make the surprising discovery that etching was unnecessary. If the image to be printed was made with the oily composition and the stone moistened, he found that only the oily image received the ink while the moistened part rejected it. The printing surface was neither raised (as in letterpress printing) nor incised (as in intaglio printing): Senefelder had discovered the third method of printing.
    He arrived at a workable process over the years 1796 to 1799, and in 1800 he was granted an English patent. In the same year, lithography (or "writing on stone") was introduced into France and Senefelder himself took it to England, but it was some time before it became widespread; it was taken up by artists especially for high-quality printing of art works. Meanwhile, Senefelder improved his techniques, finding that other materials, even paper, could be used in place of stone. In fact, zinc plates were widely used from the 1820s, but the name "lithography" stuck. Although he won world renown and was honoured by most of the crowned heads of Europe, he never became rich because he dissipated his profits through restless experimenting.
    With the later application of the offset principle, initiated by Barclay, lithography has become the most widely used method of printing.

  • 44 Barnack, Oskar

    [br]
    b. 1879 Berlin, Germany
    d. January 1936 Wetzlar, Germany
    [br]
    German camera designer who conceived the first Leica camera and many subsequent models.
    [br]
    Oskar Barnack was an optical engineer, introspective and in poor health, when in 1910 he was invited through the good offices of his friend the mechanical engineer Emil Mechau, who worked for Ernst Leitz, to join the company at Wetzlar to work on research into microscope design. He was engaged after a week's trial, and on 2 January 1911 he was put in charge of microscope research. He was an enthusiastic photographer, but excursions with his large and heavy plate camera equipment taxed his strength. In 1912, Mechau was working on a revolutionary film projector design and needed film to test it. Barnack suggested that it was not necessary to buy an expensive commercial machine— why not make one? Leitz agreed, and Barnack constructed a 35 mm movie camera, which he used to cover events in and around Wetzlar.
    The exposure problems he encountered with the variable sensitivity of the cine film led him to consider the design of a still camera in which short lengths of film could be tested before shooting—a kind of exposure-meter camera. Dissatisfied with the poor picture quality of his first model, which took the standard cine frame of 18×24 mm, he built a new model in which the frame size was doubled to 36×24 mm. It used a simple focal-plane shutter adjustable to 1/500 of a second, and a Zeiss Milar lens of 42 mm focal length. This is what is now known as the UR-Leica. Using his new camera, 1/250 of the weight of his plate equipment, Barnack made many photographs around Wetzlar, giving postcard-sized prints of good quality.
    Ernst Leitz Junior was lent the camera for his trip in June 1914 to America, where he was urged to put it into production. Visiting George Eastman in Rochester, Leitz passed on Barnack's requests for film of finer grain and better quality. The First World War put an end to the chances of developing the design at that time. As Germany emerged from the postwar chaos, Leitz Junior, then in charge of the firm, took Barnack off microscope work to design prototypes for a commercial model. Leitz's Chief Optician, Max Berek, designed a new lens, the f3.5 Elmax, for the new camera. They settled on the name Leica, and the first production models went on show at the Leipzig Spring Fair in 1925. By the end of the year, 1,000 cameras had been shipped, despite costing about two months' good wages.
    The Leica camera established 35 mm still photography as a practical proposition, and film manufacturers began to create the special fine-grain films that Barnack had longed for. He continued to improve the design, and a succession of new Leica models appeared with new features, such as interchangeable lenses, coupled range-finders, 250 exposures. By the time of his sudden death in 1936, Barnack's life's work had forever transformed the nature of photography.

    SUBJECT AREA: Textiles
    [br]
    b. 15 November 1780 Stonnington Point, Connecticut, USA
    d. 2 May 1871 Manchester, England
    [br]
    American inventor of a popular type of roving frame for cotton manufacture.
    [br]
    As a youth, Dyer constructed an unsinkable life-boat but did not immediately pursue his mechanical bent, for at 16 he entered the counting-house of a French refugee named Nancrède and succeeded to part of the business. He first went to England in 1801 and finally settled in 1811 when he married Ellen Jones (d. 1842) of Gower Street, London. Dyer was already linked with American inventors and brought to England Perkins's plan for steel engraving in 1809, shearing and nail-making machines in 1811, and also received plans and specifications for Fulton's steamboats. He seems to have acted as a sort of British patent agent for American inventors, and in 1811 took out a patent for carding engines and a card clothing machine. In 1813 there was a patent for spinning long-fibred substances such as hemp, flax or grasses, and in 1825 there was a further patent for card making machinery. Joshua Field, on his tour through Britain in 1821, saw a wire drawing machine and a leather splitting machine at Dyer's works as well as the card-making machines. At first Dyer lived in Camden Town, London, but he had a card clothing business in Birmingham. He moved to Manchester c.1816, where he developed an extensive engineering works under the name "Joseph C.Dyer, patent card manufacturers, 8 Stanley Street, Dale Street". In 1832 he founded another works at Gamaches, Somme, France, but this enterprise was closed in 1848 with heavy losses through the mismanagement of an agent. In 1825 Dyer improved on Danforth's roving frame and started to manufacture it. While it was still a comparatively crude machine when com-pared with later versions, it had the merit of turning out a large quantity of work and was very popular, realizing a large sum of money. He patented the machine that year and must have continued his interest in these machines as further patents followed in 1830 and 1835. In 1821 Dyer had been involved in the foundation of the Manchester Guardian (now The Guardian) and he was linked with the construction of the Liverpool \& Manchester Railway. He was not so successful with the ill-fated Bank of Manchester, of which he was a director and in which he lost £98,000. Dyer played an active role in the community and presented many papers to the Manchester Literary and Philosophical Society. He helped to establish the Royal Institution in London and the Mechanics Institution in Manchester. In 1830 he was a member of the delegation to Paris to take contributions from the town of Manchester for the relief of those wounded in the July revolution and to congratulate Louis-Philippe on his accession. He called for the reform of Parliament and helped to form the Anti-Corn Law League. He hated slavery and wrote several articles on the subject, both prior to and during the American Civil War.

  • 46 Howe, Elias

    [br]
    b. 9 July 1819 Spencer, Massachusetts, USA
    d. 3 October 1867 Bridgeport, Connecticut, USA
    [br]
    American inventor of one of the earliest successful sewing machines.
    [br]
    Son of Elias Howe, a farmer, he acquired his mechanical knowledge in his father's mill. He left school at 12 years of age and was apprenticed for two years in a machine shop in Lowell, Massachusetts, and later to an instrument maker, Ari Davis in Boston, Massachusetts, where his master's services were much in demand by Harvard University. Fired by a desire to invent a sewing machine, he utilized the experience gained in Lowell to devise a shuttle carrying a lower thread and a needle carrying an upper thread to make lock-stitch in straight lines. His attempts were so rewarding that he left his job and was sustained first by his father and then by a partner. By 1845 he had built a machine that worked at 250 stitches per minute, and the following year he patented an improved machine. The invention of the sewing machine had an enormous impact on the textile industry, stimulating demand for cloth because making up garments became so much quicker. The sewing machine was one of the first mass-produced consumer durables and was essentially an American invention. William Thomas, a London manufacturer of shoes, umbrellas and corsets, secured the British rights and persuaded Howe to come to England to apply it to the making of shoes. This Howe did, but he quarrelled with Thomas after less than one year. He returned to America to face with his partner, G.W.Bliss, a bigger fight over his patent (see I.M. Singer), which was being widely infringed. Not until 1854 was the case settled in his favour. This litigation threatened the very existence of the new industry, but the Great Sewing Machine Combination, the first important patent-pooling arrangement in American history, changed all this. For a fee of $5 on every domestically-sold machine and $1 on every exported one, Howe contributed to the pool his patent of 1846 for a grooved eye-pointed needle used in conjunction with a lock-stitch-forming shuttle. Howe's patent was renewed in 1861; he organized and equipped a regiment during the Civil War with the royalties. When the war ended he founded the Howe Machine Company of Bridgeport, Connecticut.

  • 47 Siemens, Sir Charles William

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

    [br]
    Irish/American pioneer of tramways for urban transport, builder and innovator of streetcars.
    [br]
    Stephenson's parents emigrated to the United States when he was 2 years old; he was educated in public schools in New York, where his parents had settled, and at a Wesleyan seminary. He became a clerk in a store at 16, but in 1828 he apprenticed himself to a coachbuilder, Andrew Wade, of Broome Street, New York. His apprenticeship lasted two years, during which time he learned mechanical drawing in the evenings and started to design vehicles. He was employed for a year on carriage repair work and in 1831 he opened his own coach repair business. Within a year he had built New York's first omnibus; this was bought by Abraham Brower, Stephenson's former employer, who started the city's first bus service. Brower immediately ordered a further three buses from Stephenson, and a further horse-drawn car was ordered by the New York \& Harlem Railroad. He built the car used at the opening of the railroad on 26 November 1832, the first street railway in the world. Orders followed for cars for many street railroads in other cities in the eastern States, and business prospered until the financial panic of 1837. Stephenson's factory was forced to close but he managed to pay off his creditors in the next six years and started in business again, building only omnibuses and coaches to become recognized as the world's foremost builder of streetcars. His first car had four flanged wheels, and a body of three compartments slung on leather straps from an unsprung chassis. He built horse-drawn cars, cable cars, electric and open cars; by 1891 his factory had 500 employees and was producing some twenty-five cars a week. His first patent had been dated 23 April 1833 and was followed by some ten others. During the Civil War, his factory was turned over to the manufacture of pontoons and gun carriages. He married Julia Tiemann in 1833; they had two sons and a daughter. He lived at New Rochelle, New York, from 1865 until his death.

    [br]
    American engineer who improved zip fasteners so they became both a practical and a commercial proposition.
    [br]
    The zip fastener was originally patented in the USA in 1896 by W.L. Judson of Chicago. At first it was used only in boots and shoes and was not a success because it tended to jam or spring open. It was expensive, for it was made largely by hand. Eventually the Automatic Hook and Eye Company of Hoboken, New Jersey, took on Dr Gideon Sundback, a Swedish electrical engineer who had settled in the United States in 1905. After several years' work Sundback filed a patent application and his model was sold as a novelty item but was still unsatisfactory in use. In 1912 he invented a hookless fastener which looked promising but also was impractical in use. Finally, in 1913, he invented a fastener which in all important essentials was the modern zip fastener and, in addition, he invented the machinery to produce it. However, clothing manufacturers continued to oppose its introduction until in 1918 a contractor making flying suits for the United States Navy placed an order for 10,000 fasteners and in 1923 B.F.Goodrich \& Co. put zips in the galoshes that they manufactured. Success was assured from then on.

  • 51 Mendelsohn, Erich

    [br]
    b. 21 March 1887 Allenstein, East Prussia
    d. 15 September 1953 San Francisco, California, USA
    [br]
    German architect, a pioneering innovator in the modern International style of building that developed in Germany during the early 1920s.
    [br]
    In some examples of his work Mendelsohn envisaged bold, sculptural forms, dramatically expressed in light and shade, which he created with extensive use of glass, steel and concrete. Characteristic of his type of early Expressionism was his design for the Einstein Tower (1919), a physical laboratory and observatory that was purpose built for Professor Einstein's research work at Neubabelsburg near Berlin in 1921. As its shape suggests, this structure was intended to be made from poured concrete but, due to technical problems, it was erected in stucco-faced steel and brickwork. Equally dramatic and original were Mendelsohn's department stores, for example the pace-setting Schocken Stores at Stuttgart (1926) and Chemnitz (1928), the Petersdorff Store at Breslau (1927) (now Wrocaw in Poland), and a very different building, the Columbus Haus in Berlin (1929–31). One of his most original designs was also in this city, that for the complex on the great boulevard, the Kurfürstendamm, which included the Universum Cinema (1928). Mendelsohn moved to England in 1933, a refugee from Nazism, and there entered into partnership with another émigré, Serge Chermayeff from Russia. Together they were responsible for a building on the seafront at Bexhill-on-Sea, the De La Warr arts and entertainments pavilion (1935–6). This long, low, glass, steel and concrete structure was ahead of its time in England and comprised a theatre and restaurant; in the centre of the façade, facing the sea, is its chief architectural feature, a semicircular glazed staircase. Soon Mendelsohn moved on to Palestine, where he was responsible for the Government Hospital at Haifa (1937) and the Hadassah University Medical Centre in Jerusalem (1936); in both cases he skilfully adapted his mode to different climatic needs. He finally settled in the USA in 1941, where his most notable buildings are the Maimonides Hospital in San Francisco and the synagogues and Jewish community centres which he built in a number of American cities.

  • 52 Rickover, Admiral Hyman George

    [br]
    b. 27 January 1900 Russian Poland
    d. 8 July 1986 Arlington, Virginia, USA
    [br]
    Polish/American naval officer, one of the principal architects of the United States nuclear submarine programme.
    [br]
    Born in Poland, Rickover was brought to the United States early in his life by his father, who settled in Chicago as a tailor. Commissioned into the US Navy in 1922, he specialized in electrical engineering (graduating from the US Naval Postgraduate School, Columbia, in 1929), quali-fied as a Submariner in 1931 and then held various posts until appointed Head of the Electrical Section of the Bureau of Ships in 1939. He held this post until the end of the Second World War.
    Rickover was involved briefly in the "Manhattan" atomic bomb project before being assigned to an atomic energy submarine project in 1946. Ultimately he was made responsible for the development and building of the world's first nuclear submarine, the USS Nautilus. He was convinced of the need to make the nuclear submarine an instrument of strategic importance, and this led to the development of the ballistic missile submarine and the Polaris programme.
    Throughout his career he was no stranger to controversy; indeed, his remaining on the active service list as a full admiral until the age of 82 (when forced to retire on the direct intervention of the Navy Secretary) indicates a man beyond the ordinary. He imposed his will on all around him and backed it with a brilliant and clear-thinking brain; his influence was even felt by the Royal Navy during the building of the first British nuclear submarine, HMS Dreadnought. He made many friends, but he also had many detractors.
    [br]
    Principal Honours and Distinctions
    US Distinguished Service Medal with Gold Star. Honorary CBE. US Congress Special Gold Medal 1959. Numerous awards and honorary degrees.
    Bibliography
    Rickover wrote several treatises on education and on the education of engineers. He also wrote on several aspects of the technical history of the US Navy.

  • 53 Train, George Francis

    [br]
    b. 24 March 1829 Boston, Massachusetts, USA d. 1904
    [br]
    American entrepreneur who introduced tramways to the streets of London.
    [br]
    He was the son of a merchant, Oliver Train, who had settled in New Orleans, Louisiana. His mother and sister died in a yellow fever epidemic and he was sent to live on his grandmother's farm at Waltham, Massachusetts, where he went to the district school. He left in 1843 and was apprenticed in a grocery store in nearby Cambridge, where, one day, a relative named Enoch Train called to see him. George Train left and went to join his relative's shipping office across the river in Boston; Enoch Train, among other enterprises, ran a packet line to Liverpool and, in 1850, sent George to England to manage his Liverpool office. Three years later, George Train went to Melbourne, Australia, and established his own shipping firm; he is said to have earned £95,000 in his first year there. In 1855 he left Australia to travel in Europe and the Levant where he made many contacts. In the late 1850s and early 1860s he was in England seeking capital for American railroads and promoting the construction of street railways or trams in Liverpool, London and Staffordshire. In 1862 he was back in Boston, where he was put in jail for disturbing a public meeting; in 1870, he achieved momentary fame for travelling around the world in eighty days.

  • 54 Winsor, Frederick Albert

    SUBJECT AREA: Public utilities
    [br]
    b. 1763 Brunswick, Germany
    d. 11 May 1830 Paris, France
    [br]
    German pioneer of gas lighting,
    [br]
    He was born Frederic Albrecht Winzer but anglicized his name after settling in England. His interest in gas lighting was aroused by the experiments of Philippe Lebon in Paris in 1802. Winsor had little scientific knowledge or engineering ability, but was well endowed with confidence and enterprise. He alone among the early practitioners of gas-making envisaged a central plant supplying a number of users through gas mains. He managed to discover the essentials of Lebon's process and tried without success to exploit it on the European continent. So he moved to England in 1803 and settled first in Grosvenor Square and then in Pall Mall. He gave public demonstrations of gas lighting at the Lyceum Theatre in London and in 1804 took out his first patent. In December he lit Pall Mall, the first street to be illuminated by gas. Winsor then began to promote a grandiose scheme for the formation of a National Light and Heat Company. He struggled against bitter opposition both in and out of Parliament to obtain sanction for his company, and it was only after the third attempt that the Gas Light \& Coke Company received its charter in 1812. However, Winsor lacked the knowledge to devise successful gas-producing plant, even with the help of the German immigrant chemist F.C.Accum. Winsor was dismissed in 1812 and returned to Paris the following year, while the company recovered with the appointment of an able engineer, Samuel Clegg. Winsor formed a company in Paris to install gas lighting, but that failed in 1819.

    b. 25 November 1835 Dunfermline, Fife, Scotland
    d. 11 August 1919 Lenox, Massachusetts, USA
    [br]
    Scottish industrialist and philanthropist.
    [br]
    Andrew Carnegie was a highly successful entrepreneur and steel industrialist rather than an engineer, but he made a significant contribution to engineering both through his work in industry and through his philanthropic and educational activities. His parents emigrated to the United States in 1848 and the family settled in Pennsylvania. Beginning as a telegraph boy in Pittsburgh in 1850, the young Carnegie rose through successful enterprises in railways, bridges, locomotives and rolling stock, pursuing a process of "Vertical integration" in the iron and steel industry which led to him becoming the leading American ironmaster by 1881. His interests in the Carnegie Steel Company were incorporated in the United States Steel Corporation in 1901, when Carnegie retired from business and devoted himself to philanthropy. He was particularly involved in benefactions to provide public libraries in the United States, Great Britain and other English-speaking countries. Remembering his ancestry, he was especially generous toward Scottish universities, as a result of which he was elected Rector of the University of St Andrews, Scotland's oldest university, by its students. Other large endowments were made for funds in recognition of heroic deeds, and he financed the building of the Temple of Peace at The Hague.

  • 57 Glenck, Karl Christian Friedrich

    [br]
    b. 13 April 1779 Schwäbisch Hall, Germany
    d. 21 November 1845 Gotha, Germany
    [br]
    German salt-mining expert who introduced large-scale salt explorations.
    [br]
    Having studied law at the University of Erlangen, he became Confidential Secretary to the Prince of Hohenlohe-Ingelfingen, in whose territory his father had been in charge of a saltworks. When this small country fell to Württemberg in 1806, Glenck continued his mineralogical and geological studies in order to develop methods of finding deposits of salt. He was the first to carry out systematic large-scale salt explorations in Germany, mostly in southern and central parts, and achieved remarkable results that far exceeded former non-systematic findings. He worked either on behalf of governments or companies or at his own risk, and in the early 1820s he settled in Gotha to live in the centre of the regions of greatest interest to him.
    His career began in 1819 with the discovery of the deposits of Ludwigshall near Wimpfen, Neckar, and prospecting salt near Basel in 1836 was his greatest success: Schweizerhall, opened one year later, made Switzerland self-sufficient in salt production. For fifteen years he had invested large sums into this project, which became the fifth salt-works to come into existence due to his drilling. Glenck worked with stir rods and he developed several new technical devices, such as casing the bore holes with iron pipes instead of wood (1830), and using wooden instead of iron rods to reduce the weight (1834). A flexible connection between rod and drill was to be introduced later by Karl von Oeynhausen. One of Glenck's most important followers in the field of deep-drilling was K.G. Kind.

  • 58 Holtzapffel, Charles

    [br]
    b. 1806 London, England
    d. 11 April 1847 London, England
    [br]
    English mechanical engineer and author of Turning and Mechanical Manipulation.
    [br]
    Charles Holtzapffel was the son of John Holtzapffel, a native of Germany who settled in London c.1787 and set up as a manufacturer of lathes and tools for amateur mechanics. Charles Holtzapffel received a good English education and training in his father's workshop, and subsequently became a partner and ultimately succeeded to the business. He was engaged in the construction of machinery for printing banknotes, of lathes for cutting rosettes and for ornamental and plain turning. Holtzapffel is chiefly remembered for his monumental work entitled Turning and Mechanical Manipulation, intended as a work of general reference and practical instruction on the lathe. Publication began in 1843 and only the first two volumes were published in his lifetime. A third volume was edited by his widow from his notes and published shortly after his death. The fourth and fifth volumes were completed by his son, John Jacob Holtzapffel, more than thirty years later. Holtzapffel was an Associate of the Institution of Civil Engineers and served on its Council: he was also a member of the Society of Arts and Chairman of its Committee on Mechanics.

  • 59 Moore, Hiram

    [br]
    b. 19 July 1801 New England, USA
    d. c. 1874 Wisconsin, USA
    [br]
    American farmer and inventor who developed the first combine harvester.
    [br]
    Hiram Moore was the son of a New England stonemason. In 1831 he moved to West Michigan to farm, and he and his two brothers settled in Climax in Kalamazoo County.
    Stimulated by a conversation with his neighbour, John Hascall, Moore made a model harvesting machine, which he patented in 1834. By the following year he had built a full-scale machine, but it broke down very quickly. In 1835 he successfully harvested 3 acres left standing for the purpose. Each year alterations and additions were made to the machine, and by 1839 over 50 acres were successfully harvested and threshed in the one operation by the Moore-Hascall machine.
    During further developments which took place in the 1840s, Moore sold much of his interest to Senator Lucius Lyon. By the late 1840s this source of funding was no longer available, and attempts to extend the patent became embroiled in similar attempts by McCormick and Hussey and were blocked by rural pressures stemming from the fear that high machinery prices would ensue if the patents continued.
    Discouraged, Moore moved to Brandon, Wisconsin, where he farmed 600 acres. He was still developing various machines, but was no longer actively involved in the development of the combine harvester. He continued to work his own machine, with which he would cut just a few acres each year.

    b. 17 September 1857 (5 September 1857, Old Style) Izhevskoye, Russia
    d. 19 September 1935 Kaluga, Russia.
    [br]
    Russian pioneer space theorist.
    [br]
    The son of a Polish lumberjack who had settled in Russia, Tsiolkovsky was a largely self-educated schoolteacher who was practically deaf from childhood. In spite of this handicap, he studied the problems of space and spaceflight and arrived at most of the correct theoretical solutions. In 1883 he noted that the gas escaping from a vehicle moving into space would drive the containing vehicle away from it. He wrote a remarkable series of technical articles and papers including, in 1903, a seminal article, "Exploration of Space with Reactive Devices". His aerodynamic experiments did not receive any significant recognition from the Academy of Sciences, and his design for an all-metal dirigible was largely ignored at the 1914 Aeronautics Congress in St Petersburg. However, from the inception of the Soviet Union until his death, Tsiolkovsky continued his research with state support, and on 9 November 1921 he was granted a pension for life by the Council of the People's Commissars. He has rightly been described as the "Grandfather of Spaceflight" and as a fine theoretical engineer who established most of the principles upon which rocket technology is based.
