  • 101 Hopkinson, John

    [br]
    b. 27 July 1849 Manchester, England
    d. 27 August 1898 Petite Dent de Veisivi, Switzerland
    [br]
    English mathematician and electrical engineer who laid the foundations of electrical machine design.
    [br]
    After attending Owens College, Manchester, Hopkinson was admitted to Trinity College, Cambridge, in 1867 to read for the Mathematical Tripos. An appointment in 1872 with the lighthouse department of the Chance Optical Works in Birmingham directed his attention to electrical engineering. His most noteworthy contribution to lighthouse engineering was an optical system to produce flashing lights that distinguished between individual beacons. His extensive researches on the dielectric properties of glass were recognized when he was elected to a Fellowship of the Royal Society at the age of 29. Moving to London in 1877 he became established as a consulting engineer at a time when electricity supply was about to begin on a commercial scale. During the remainder of his life, Hopkinson's researches resulted in fundamental contributions to electrical engineering practice, dynamo design and alternating current machine theory. In making a critical study of the Edison dynamo he developed the principle of the magnetic circuit, a concept also arrived at by Gisbert Kapp around the same time. Hopkinson's improvement of the Edison dynamo by reducing the length of the field magnets almost doubled its output. In 1890, in addition to-his consulting practice, Hopkinson accepted a post as the first Professor of Electrical Engineering and Head of the Siemens laboratory recently established at King's College, London. Although he was not involved in lecturing, the position gave him the necessary facilities and staff and student assistance to continue his researches. Hopkinson was consulted on many proposals for electric traction and electricity supply, including schemes in London, Manchester, Liverpool and Leeds. He also advised Mather and Platt when they were acting as contractors for the locomotives and generating plant for the City and South London tube railway. As early as 1882 he considered that an ideal method of charging for the supply of electricity should be based on a two-part tariff, with a charge related to maximum demand together with a charge for energy supplied. Hopkinson was one the foremost expert witnesses of his day in patent actions and was himself the patentee of over forty inventions, of which the three-wire system of distribution and the series-parallel connection of traction motors were his most successful. Jointly with his brother Edward, John Hopkinson communicated the outcome of his investigations to the Royal Society in a paper entitled "Dynamo Electric Machinery" in 1886. In this he also described the later widely used "back to back" test for determining the characteristics of two identical machines. His interest in electrical machines led him to more fundamental research on magnetic materials, including the phenomenon of recalescence and the disappearance of magnetism at a well-defined temperature. For his work on the magnetic properties of iron, in 1890 he was awarded the Royal Society Royal Medal. He was a member of the Alpine Club and a pioneer of rock climbing in Britain; he died, together with three of his children, in a climbing accident.

    b. 2 September 1852 Mauer, Vienna, Austria
    d. 10 August 1922 Birmingham, England
    [br]
    Austrian (naturalized British in 1881) engineer and a pioneer of dynamo design, being particularly associated with the concept of the magnetic circuit.
    [br]
    Kapp entered the Polytechnic School in Zurich in 1869 and gained a mechanical engineering diploma. He became a member of the engineering staff at the Vienna International Exhibition of 1873, and then spent some time in the Austrian navy before entering the service of Gwynne \& Co. of London, where he designed centrifugal pumps and gas exhausters. Kapp resolved to become an electrical engineer after a visit to the Paris Electrical Exhibition of 1881 and in the following year was appointed Manager of the Crompton Co. works at Chelmsford. There he developed and patented the dynamo with compound field winding. Also at that time, with Crompton, he patented electrical measuring instruments with over-saturated electromagnets. He became a naturalized British subject in 1881.
    In 1886 Kapp's most influential paper was published. This described his concept of the magnetic circuit, providing for the first time a sound theoretical basis for dynamo design. The theory was also developed independently by J. Hopkinson. After commencing practice as a consulting engineer in 1884 he carried out design work on dynamos and also electricity-supply and -traction schemes in Germany, Italy, Norway, Russia and Switzerland. From 1891 to 1894 much of his time was spent designing a new generating station in Bristol, officially as Assistant to W.H. Preece. There followed an appointment in Germany as General Secretary of the Verband Deutscher Electrotechniker. For some years he edited the Electrotechnische Zeitschrift and was also a part-time lecturer at the Charlottenberg Technical High School in Berlin. In 1904 Kapp was invited to accept the new Chair of Electrical Engineering at the University of Birmingham, which he occupied until 1919. He was the author of several books on electrical machine and transformer design.

  • 103 Lucas, Anthony Francis

    [br]
    b. 9 September 1855 Spalato, Dalmatia, Austria-Hungary (now Split, Croatia)
    d. 2 September 1921 Washington, DC, USA
    [br]
    Austrian (naturalized American) mining engineer who successfully applied rotary drilling to oil extraction.
    [br]
    A former Second Lieutenant of the Austrian navy (hence his later nickname "Captain") and graduate of the Polytechnic Institute of Graz, Lucas decided to stay in Michigan when he visited his relatives in 1879. He changed his original name, Lucie, into the form his uncle had adopted and became a naturalized American citizen at the age of 30. He worked in the lumber industry for some years and then became a consulting mechanical and mining engineer in Washington, DC. He began working for a salt-mining company in Louisiana in 1893 and became interested in the geology of the Mexican Gulf region, with a view to prospecting for petroleum. In the course of this work he came to the conclusion that the hills in this elevated area, being geological structures distinct from the surrounding deposits, were natural reservoirs of petroleum. To prove his unusual theory he subsequently chose Spindle Top, near Beaumont, Texas, where in 1899 he began to bore a first oil-well. A second drill-hole, started in October 1900, was put through clay and quicksand. After many difficulties, a layer of rock containing marine shells was reached. When the "gusher" came out on 10 January 1901, it not only opened up a new era in the oil and gas business, but it also led to the future exploration of the terrestrial crust.
    Lucas's boring was a breakthrough for the rotary drilling system, which was still in its early days although its principles had been established by the English engineer Robert Beart in his patent of 1884. It proved to have advantages over the pile-driving of pipes. A pipe with a simple cutter at the lower end was driven with a constantly revolving motion, grinding down on the bottom of the well, thus gouging and chipping its way downward. To deal with the quicksand he adopted the use of large and heavy casings successively telescoped one into the other. According to Fauvelle's method, water was forced through the pipe by means of a pump, so the well was kept full of circulating liquid during drilling, flushing up the mud. When the salt-rock was reached, a diamond drill was used to test the depth and the character of the deposit.
    When the well blew out and flowed freely he developed a preventer in order to save the oil and, even more importantly at the time, to shut the well and to control the oil flow. This assembly, patented in 1903, consisted of a combined system of pipes, valves and casings diverting the stream into a horizontal direction.
    Lucas's fame spread around the world, but as he had to relinquish the larger part of his interest to the oil company supporting the exploration, his financial reward was poor. One year after his success at Spindle Top he started oil exploration in Mexico, where he stayed until 1905, when he resumed his consulting practice in Washington, DC.

  • 104 Sopwith, Sir Thomas (Tommy) Octave Murdoch

    SUBJECT AREA: Aerospace
    [br]
    b. 18 January 1888 London, England
    d. 27 January 1989 Stockbridge, Hampshire, England
    [br]
    English aeronautical engineer and industrialist.
    [br]
    Son of a successful mining engineer, Sopwith did not shine at school and, having been turned down by the Royal Navy as a result, attended an engineering college. His first interest was motor cars and, while still in his teens, he set up a business in London with a friend in order to sell them; he also took part in races and rallies.
    Sopwith's interest in aviation came initially through ballooning, and in 1906 he purchased his own balloon. Four years later, inspired by the recent flights across the Channel to France and after a joy-ride at Brooklands, he bought an Avis monoplane, followed by a larger biplane, and taught himself to fly. He was awarded the Royal Aero Society's Aviator Certificate No. 31 on 21 November 1910, and he quickly distinguished himself in flying competitions on both sides of the Atlantic and started his own flying school. In his races he was ably supported by his friend Fred Sigrist, a former motor engineer. Among the people Sopwith taught to fly were an Australian, Harry Hawker, and Major Hugh Trenchard, who later became the "father" of the RAF.
    In 1912, depressed by the poor quality of the aircraft on trial for the British Army, Sopwith, in conjunction with Hawker and Sigrist, bought a skating rink in Kingston-upon-Thames and, assisted by Fred Sigrist, started to design and build his first aircraft, the Sopwith Hybrid. He sold this to the Royal Navy in 1913, and the following year his aviation manufacturing company became the Sopwith Aviation Company Ltd. That year a seaplane version of his Sopwith Tabloid won the Schneider Trophy in the second running of this speed competition. During 1914–18, Sopwith concentrated on producing fighters (or "scouts" as they were then called), with the Pup, the Camel, the 1½ Strutter, the Snipe and the Sopwith Triplane proving among the best in the war. He also pioneered several ideas to make flying easier for the pilot, and in 1915 he patented his adjustable tailplane and his 1 ½ Strutter was the first aircraft to be fitted with air brakes. During the four years of the First World War, Sopwith Aviation designed thirty-two different aircraft types and produced over 16,000 aircraft.
    The end of the First World War brought recession to the aircraft industry and in 1920 Sopwith, like many others, put his company into receivership; none the less, he immediately launched a new, smaller company with Hawker, Sigrist and V.W.Eyre, which they called the H.G. Hawker Engineering Company Ltd to avoid any confusion with the former company. He began by producing cars and motor cycles under licence, but was determined to resume aircraft production. He suffered an early blow with the death of Hawker in an air crash in 1921, but soon began supplying aircraft to the Royal Air Force again. In this he was much helped by taking on a new designer, Sydney Camm, in 1923, and during the next decade they produced a number of military aircraft types, of which the Hart light bomber and the Fury fighter, the first to exceed 200 mph (322 km/h), were the best known. In the mid-1930s Sopwith began to build a large aviation empire, acquiring first the Gloster Aircraft Company and then, in quick succession, Armstrong-Whitworth, Armstrong-Siddeley Motors Ltd and its aero-engine counterpart, and A.V.Roe, which produced Avro aircraft. Under the umbrella of the Hawker Siddeley Aircraft Company (set up in 1935) these companies produced a series of outstanding aircraft, ranging from the Hawker Hurricane, through the Avro Lancaster to the Gloster Meteor, Britain's first in-service jet aircraft, and the Hawker Typhoon, Tempest and Hunter. When Sopwith retired as Chairman of the Hawker Siddeley Group in 1963 at the age of 75, a prototype jump-jet (the P-1127) was being tested, later to become the Harrier, a for cry from the fragile biplanes of 1910.
    Sopwith also had a passion for yachting and came close to wresting the America's Cup from the USA in 1934 when sailing his yacht Endeavour, which incorporated a number of features years ahead of their time; his greatest regret was that he failed in his attempts to win this famous yachting trophy for Britain. After his retirement as Chairman of the Hawker Siddeley Group, he remained on the Board until 1978. The British aviation industry had been nationalized in April 1977, and Hawker Siddeley's aircraft interests merged with the British Aircraft Corporation to become British Aerospace (BAe). Nevertheless, by then the Group had built up a wide range of companies in the field of mechanical and electrical engineering, and its board conferred on Sopwith the title Founder and Life President.

  • 105 Stevenson, Robert

    [br]
    b. 8 June 1772 Glasgow, Scotland
    d. 12 July 1850 Edinburgh, Scotland
    [br]
    Scottish lighthouse designer and builder.
    [br]
    After his father's death when he was only 2 years old, Robert Stevenson was educated at a school for children from families in reduced circumstances. However, c. 1788 his mother married again, to Thomas Smith, Engineer to the Northern Lighthouse Board. Stevenson then served an apprenticeship under his new stepfather. The Board, which is still an active force in the 1990s, was founded in 1786 to oversee the lights and buoyage in some of the wildest waters in Western Europe, the seas around the coasts of Scotland and the Isle of Man.
    After studies at Andersen's College (now the University of Strathclyde) and later at Edinburgh University, Stevenson assumed responsibility in the field for much of the construction work sanctioned by the Board. After some years he succeeded Smith as Engineer to the Board and thereby the long connection between the Northern Lights and the Stevenson family commenced.
    Stevenson became Engineer to the Board when he was about 30 years old, remaining in that office for the best part of half a century. During these years he improved catoptric lighting, adopted the central lamp refracting system and invented the intermittent flashing light. While these developments were sufficient to form a just memorial to the man, he was involved in greater endeavours in the construction of around twenty lighthouses, most of which had ingenious forms of construction. The finest piece was the Bell Rock Lighthouse, built on a reef off the Scottish East Coast. This enterprise took five years to complete and can be regarded as the most important construction of his life.
    His interests fitted in with those of the other great men living in and around Edinburgh at the time, and included oceanography, astronomy, architecture and antiquarian studies. He designed several notable bridges, proposed a design for the rails for railways and also made a notable study of marine timber borers. He contributed to Encyclopaedia Britannica and to many journals.
    His grandson, born in the year of his death, was the famous author Robert Louis Stevenson (1850–94).

    SUBJECT AREA: Civil engineering
    [br]
    b. c. 1590 St Maartensdijk, Zeeland, the Netherlands
    d. 4 February 1656 probably London, England
    [br]
    Dutch/British civil engineer responsible for many of the drainage and flood-protection schemes in low-lying areas of England in the seventeenth century.
    [br]
    At the beginning of the seventeenth century, several wealthy men in England joined forces as "adventurers" to put their money into land ventures. One such group was responsible for the draining of the Fens. The first need was to find engineers who were versed in the processes of land drainage, particularly when that land was at, or below, sea level. It was natural, therefore, to turn to the Netherlands to find these skilled men. Joachim Liens was one of the first of the Dutch engineers to go to England, and he started work on the Great Level; however, no real progress was made until 1621, when Cornelius Vermuyden was brought to England to assist in the work.
    Vermuyden had grown up in a district where he could see for himself the techniques of embanking and reclaiming land from the sea. He acquired a reputation of expertise in this field, and by 1621 his fame had spread to England. In that year the Thames had flooded and breached its banks near Havering and Dagenham in Essex. Vermuyden was commissioned to repair the breach and drain neighbouring marshland, with what he claimed as complete success. The Commissioners of Sewers for Essex disputed this claim and whthheld his fee, but King Charles I granted him a portion of the reclaimed land as compensation.
    In 1626 Vermuyden carried out his first scheme for drainage works as a consultant. This was the drainage of Hatfield Chase in South Yorkshire. Charles I was, in fact, Vermuyden's employer in the drainage of the Chase, and the work was undertaken as a means of raising additional rents for the Royal Exchequer. Vermuyden was himself an "adventurer" in the undertaking, putting capital into the venture and receiving the title to a considerable proportion of the drained lands. One of the important elements of his drainage designs was the principal of "washes", which were flat areas between the protective dykes and the rivers to carry flood waters, to prevent them spreading on to nearby land. Vermuyden faced bitter opposition from those whose livelihoods depended on the marshlands and who resorted to sabotage of the embankments and violence against his imported Dutch workmen to defend their rights. The work could not be completed until arbiters had ruled out on the respective rights of the parties involved. Disagreements and criticism of his engineering practices continued and he gave up his interest in Hatfield Chase. The Hatfield Chase undertaking was not a great success, although the land is now rich farmland around the river Don in Doncaster. However, the involved financial and land-ownership arrangements were the key to the granting of a knighthood to Cornelius Vermuyden in January 1628, and in 1630 he purchased 4,000 acres of low-lying land on Sedgemoor in Somerset.
    In 1629 Vermuyden embarked on his most important work, that of draining the Great Level in the fenlands of East Anglia. Francis Russell, 4th Earl of Bedford, was given charge of the work, with Vermuyden as Engineer; in this venture they were speculators and partners and were recompensed by a grant of land. The area which contains the Cambridgeshire tributaries of the Great Ouse were subject to severe and usually annual flooding. The works to contain the rivers in their flood period were important. Whilst the rivers were contained with the enclosed flood plain, the land beyond became highly sought-after because of the quality of the soil. The fourteen "adventurers" who eventually came into partnership with the Earl of Bedford and Vermuyden were the financiers of the scheme and also received land in accordance with their input into the scheme. In 1637 the work was claimed to be complete, but this was disputed, with Vermuyden defending himself against criticism in a pamphlet entitled Discourse Touching the Great Fennes (1638; 1642, London). In fact, much remained to be done, and after an interruption due to the Civil War the scheme was finished in 1652. Whilst the process of the Great Level works had closely involved the King, Oliver Cromwell was equally concerned over the success of the scheme. By 1655 Cornelius Vermuyden had ceased to have anything to do with the Great Level. At that stage he was asked to account for large sums granted to him to expedite the work but was unable to do so; most of his assets were seized to cover the deficiency, and from then on he subsided into obscurity and poverty.
    While Cornelius Vermuyden, as a Dutchman, was well versed in the drainage needs of his own country, he developed his skills as a hydraulic engineer in England and drained acres of derelict flooded land.

  • 107 Maudslay, Henry

    [br]
    b. 22 August 1771 Woolwich, Kent, England
    d. 15 February 1831 Lambeth, London, England
    [br]
    English precision toolmaker and engineer.
    [br]
    Henry Maudslay was the third son of an ex-soldier and storekeeper at Woolwich Arsenal. At the age of 12 he was employed at the Arsenal filling cartridges; two years later he was transferred to the woodworking department, adjacent to the smithy, to which he moved when 15 years old. He was a rapid learner, and three years later Joseph Bramah took him on for the construction of special tools required for the mass-production of his locks. Maudslay was thus employed for the next eight years. He became Bramah's foreman, married his housekeeper, Sarah Tindale, and, unable to better himself, decided to leave and set up on his own. He soon outgrew his first premises in Wells Street and moved to Margaret Street, off Oxford Street, where some examples of his workmanship were displayed in the window. These caught the attention of a visiting Frenchman, de Bacquancourt; he was a friend of Marc Isambard Brunel, who was then in the early stages of designing the block-making machinery later installed at Portsmouth dockyard.
    Brunel wanted first a set of working models, as he did not think that the Lords of the Admiralty would be capable of understanding engineering drawings; Maudslay made these for him within the next two years. Sir Samuel Bentham, Inspector-General of Naval Works, agreed that Brunel's system was superior to the one that he had gone some way in developing; the Admiralty approved, and an order was placed for the complete plant. The manufacture of the machinery occupied Maudslay for the next six years; he was assisted by a draughtsman whom he took on from Portsmouth dockyard, Joshua Field (1786–1863), who became his partner in Maudslay, Son and Field. There were as many as eighty employees at Margaret Street until, in 1810, larger premises became necessary and a new works was built at Lambeth Marsh where, eventually, there were up to two hundred workers. The new factory was flanked by two houses, one of which was occupied by Maudslay, the other by Field. The firm became noted for its production of marine steam-engines, notably Maudslay's table engine which was first introduced in 1807.
    Maudslay was a consummate craftsman who was never happier than when working at his bench or at a machine tool; he was also one of the first engineers to appreciate the virtues of standardization. Evidence of this appreciation is to be found in his work in the development of the Bramah lock and then on the machine tools for the manufacture of ship's blocks to Marc Brunel's designs; possibly his most important contribution was the invention in 1797 of the metal lathe. He made a number of surface plates of the finest quality. The most celebrated of his numerous measuring devices was a micrometer-based machine which he termed his "Lord Chancellor" because, in the machine shop, it represented the "final court of appeal", measuring to one-thousandth of an inch.

    CAMINO DE SANTIAGO The Camino de Santiago is a medieval pilgrim route stretching from the Pyrenees to Santiago de Compostela in northwest Spain, where tradition has it that the body of Saint James the Apostle (Spain's patron saint) is buried. Those who had made the long, dangerous journey returned proudly wearing on their hat or cloak the venera or concha (scallop shell) traditionally associated with this pilgrimage - Saint James' body had reportedly been found covered in scallops. Today this symbolic shell can still be seen all along the Camino de Santiago, carved on ancient buildings and painted on modern-day road signs marking the historic route for the benefit of tourists and pilgrims. In astronomy the Camino de Santiago is another name for the Vía Láctea (Milky Way), hence the title of Buñuel's famous satirical film about the route to Compostela.

    CAMINO DE SANTIAGO
    The Galician city of Santiago de Compostela in northwestern Spain, traditionally held to be the burial site of the Apostle St James, was one of the most important Christian pilgrimage centres in Europe during the Middle Ages, second only to Rome. Countless pilgrims made the journey from different parts of Europe to Santiago along recognized pilgrimage routes. The main one crosses the north of Spain from the Pyrenees to Galicia and is known as the Camino de Santiago. Although its religious significance has declined, it has become a popular tourist route attracting a wide range of travellers: nature lovers on day trips, hikers and cyclists, and even latter-day pilgrims, whether solitary walkers or on package tours. Many of them avail themselves of the free or low-cost accommodation provided along the way by local councils and religious institutions.

  • 113 Ader, Clément

    SUBJECT AREA: Aerospace
    [br]
    b. 2 April 1841 Muret, France
    d. 3 May 1925 Toulouse, France
    [br]
    French engineer who made a short "hop" in a powered aeroplane in 1890.
    [br]
    Ader was a distinguished engineer and versatile inventor who was involved with electrical developments, including the telephone and air-cushion vehicles. In the field of aeronautics he became the centre of a long-lasting controversy: did he, or did he not, fly before the Wright brothers' flight of 1903? In 1882 Ader started work on his first aeroplane, the Eole (god of the winds), which was bat-like in appearance and powered by a very well-designed lightweight steam engine developing about 15 kW (20 hp). On 9 October 1890 the Eole was ready, and with Ader as pilot it increased speed over a level surface and lifted off the ground. It was airborne for about 5 seconds and covered some 50 m (164 ft), reaching a height of 20 cm (8 in.). Whether such a short hop constituted a flight has caused much discussion and argument over the years. An even greater controversy followed Ader's claim in 1906 that his third aeroplane (Avion III) had made a flight of 300 m (328 yd) in 1897. He repeated this claim in his book written in 1907, and many historians accepted his account of the "flight". C.H.Gibbs-Smith, an eminent aviation historian, investigated the Ader controversy and in his book published in 1966 came to the conclusion that the Avion III did not fly at all. Avion III was donated to the Museum of the Conservatoire des Arts et Métiers in Paris, and still survives. From 1906 onwards Ader concentrated his inventive efforts elsewhere, but he did mount a successful campaign to persuade the French War Ministry to create an air force.

    [br]
    b. 31 March 1854 Glasgow, Scotland
    d. 12 November 1932 Ewhurst, Surrey, England
    [br]
    Scottish mechanical engineer, inventor of the two-stroke internal combustion engine.
    [br]
    Clerk began his engineering training at about the age of 15 in the drawing office of H.O.Robinson \& Company, Glasgow, and in his father's works. Meanwhile, he studied at the West of Scotland Technical College and then, from 1871 to 1876, at Anderson's College, Glasgow, and at the Yorkshire College of Science, Leeds. Here he worked under and then became assistant to the distinguished chemist T.E.Thorpe, who set him to work on the fractional distillation of petroleum, which was to be useful to him in his later work. At that time he had intended to become a chemical engineer, but seeing a Lenoir gas engine at work, after his return to Glasgow, turned his main interest to gas and other internal combustion engines. He pursued his investigations first at Thomson, Sterne \& Company (1877–85) and then at Tangyes of Birmingham (1886–88. In 1888 he began a lifelong partnership in Marks and Clerk, consulting engineers and patent agents, in London.
    Beginning his work on gas engines in 1876, he achieved two patents in the two following years. In 1878 he made his principal invention, patented in 1881, of an engine working on the two-stroke cycle, in which the piston is powered during each revolution of the crankshaft, instead of alternate revolutions as in the Otto four-stroke cycle. In this engine, Clerk introduced supercharging, or increasing the pressure of the air intake. Many engines of the Clerk type were made but their popularity waned after the patent for the Otto engine expired in 1890. Interest was later revived, particularly for application to large gas engines, but Clerk's engine eventually came into its own where simple, low-power motors are needed, such as in motor cycles or motor mowers.
    Clerk's work on the theory and design of gas engines bore fruit in the book The Gas Engine (1886), republished with an extended text in 1909 as The Gas, Petrol and Oil Engine; these and a number of papers in scientific journals won him international renown. During and after the First World War, Clerk widened the scope of his interests and served, often as chairman, on many bodies in the field of science and industry.

  • 115 Hetzel, Max

    [br]
    b. 5 March 1921 Basle, Switzerland
    [br]
    Swiss electrical engineer who invented the tuning-fork watch.
    [br]
    Hetzel trained as an electrical engineer at the Federal Polytechnic in Zurich and worked for several years in the field of telecommunications before joining the Bulova Watch Company in 1950. At that time several companies were developing watches with electromagnetically maintained balances, but they represented very little advance on the mechanical watch and the mechanical switching mechanism was unreliable. In 1952 Hetzel started work on a much more radical design which was influenced by a transistorized tuning-fork oscillator that he had developed when he was working on telecommunications. Tuning forks, whose vibrations were maintained electromagnetically, had been used by scientists during the nineteenth century to measure small intervals of time, but Niaudet- Breguet appears to have been the first to use a tuning fork to control a clock. In 1866 he described a mechanically operated tuning-fork clock manufactured by the firm of Breguet, but it was not successful, possibly because the fork did not compensate for changes in temperature. The tuning fork only became a precision instrument during the 1920s, when elinvar forks were maintained in vibration by thermionic valve circuits. Their primary purpose was to act as frequency standards, but they might have been developed into precision clocks had not the quartz clock made its appearance very shortly afterwards. Hetzel's design was effectively a miniaturized version of these precision devices, with a transistor replacing the thermionic valve. The fork vibrated at a frequency of 360 cycles per second, and the hands were driven mechanically from the end of one of the tines. A prototype was working by 1954, and the watch went into production in 1960. It was sold under the tradename Accutron, with a guaranteed accuracy of one minute per month: this was a considerable improvement on the performance of the mechanical watch. However, the events of the 1920s were to repeat themselves, and by the end of the decade the Accutron was eclipsed by the introduction of quartz-crystal watches.

    [br]
    b. 8 November 1923 Jefferson City, Missouri, USA
    [br]
    American engineer who filed the first patents for micro-electronic (integrated) circuits.
    [br]
    Kilby spent most of his childhood in Great Bend, Kansas, where he often accompanied his father, an electrical power engineer, on his maintenance rounds. Working in the blizzard of 1937, his father borrowed a "ham" radio, and this fired Jack to study for his amateur licence (W9GTY) and to construct his own equipment while still a student at Great Bend High School. In 1941 he entered the University of Illinois, but four months later, after the attack on Pearl Harbor, he was enlisted in the US Army and found himself working in a radio repair workshop in India. When the war ended he returned to his studies, obtaining his BSEE from Illinois in 1947 and his MSEE from the University of Wisconsin. He then joined Centralab, a small electronics firm in Milwaukee owned by Globe-Union. There he filed twelve patents, including some for reduced titanate capacitors and for Steatite-packing of transistors, and developed a transistorized hearing-aid. During this period he also attended a course on transistors at Bell Laboratories. In May 1958, concerned to gain experience in the field of number processing, he joined Texas Instruments in Dallas. Shortly afterwards, while working alone during the factory vacation, he conceived the idea of making monolithic, or integrated, circuits by diffusing impurities into a silicon substrate to create P-N junctions. Within less than a month he had produced a complete oscillator on a chip to prove that the technology was feasible, and the following year at the 1ERE Show he demonstrated a germanium integrated-circuit flip-flop. Initially he was granted a patent for the idea, but eventually, after protracted litigation, priority was awarded to Robert Noyce of Fairchild. In 1965 he was commissioned by Patrick Haggerty, the Chief Executive of Texas Instruments, to make a pocket calculator based on integrated circuits, and on 14 April 1971 the world's first such device, the Pocketronic, was launched onto the market. Costing $150 (and weighing some 2½ lb or 1.1 kg), it was an instant success and in 1972 some 5 million calculators were sold worldwide. He left Texas Instruments in November 1970 to become an independent consultant and inventor, working on, amongst other things, methods of deriving electricity from sunlight.

Following graduation he served an apprenticeship at the Vulcan Foundry, Glasgow, before serving first as Chief Draughtsman with the Thames shipbuilders and engineers Maudslay Sons \& Field, and later as Engineer of Paraffin Young's Works at Bathgate and West Calder in Lothian. He was credited with the inventions of many ingenious appliances and techniques for improving production in these two establishments. About 1866 Kirk returned to Glasgow as Manager of the Cranstonhill Engine Works, then moved to Elder's Shipyard (later known as the Fairfield Company) as Engineering Manager. There he made history in producing the world's first triple-expansion engines for the single-screw steamship Propontis in 1874. That decade was to confirm the Clyde's leading role as shipbuilders to the world and to establish the iron ship with efficient reciprocating machinery as the workhorse of the British Merchant Marine. Upon the death of the great Clyde shipbuilder Robert Napier in 1876, Kirk and others took over as partners in the shipbuilding yard and engine shops of Robert Napier \& Sons. There in 1881 they built a ship that is acknowledged as one of the masterpieces of British shipbuilding: the SS Aberdeen for George Thompson's Aberdeen Line to the Far East. In this ship the fullest advantage was taken of high steam temperatures and pressures, which were expanded progressively in a three-cylinder configuration. The Aberdeen, in its many voyages from London to China and Japan, was to prove the efficiency of these engines that had been so carefully designed in Glasgow. In the following years Dr Kirk (he has always been known as Doctor, although his honorary LLD was only awarded by Glasgow University in 1888) persuaded the Admiralty and several shipping companies to accept not only triple-expansion machinery but also the use of mild steel in ship construction. The successful SS Parisian, built for the Allan Line of Glasgow, was one of these pioneer ships.

  • 118 Maxim, Sir Hiram Stevens

    [br]
    b. 5 February 1840 Brockway's Mills, Maine, USA
    d. 24 November 1916 Streatham, London, England
    [br]
    American (naturalized British) inventor; designer of the first fully automatic machine gun and of an experimental steam-powered aircraft.
    [br]
    Maxim was born the son of a pioneer farmer who later became a wood turner. Young Maxim was first apprenticed to a carriage maker and then embarked on a succession of jobs before joining his uncle in his engineering firm in Massachusetts in 1864. As a young man he gained a reputation as a boxer, but it was his uncle who first identified and encouraged Hiram's latent talent for invention.
    It was not, however, until 1878, when Maxim joined the first electric-light company to be established in the USA, as its Chief Engineer, that he began to make a name for himself. He developed an improved light filament and his electric pressure regulator not only won a prize at the first International Electrical Exhibition, held in Paris in 1881, but also resulted in his being made a Chevalier de la Légion d'honneur. While in Europe he was advised that weapons development was a more lucrative field than electricity; consequently, he moved to England and established a small laboratory at Hatton Garden, London. He began by investigating improvements to the Gatling gun in order to produce a weapon with a faster rate of fire and which was more accurate. In 1883, by adapting a Winchester carbine, he successfully produced a semi-automatic weapon, which used the recoil to cock the gun automatically after firing. The following year he took this concept a stage further and produced a fully automatic belt-fed weapon. The recoil drove barrel and breechblock to the vent. The barrel then halted, while the breechblock, now unlocked from the former, continued rearwards, extracting the spent case and recocking the firing mechanism. The return spring, which it had been compressing, then drove the breechblock forward again, chambering the next round, which had been fed from the belt, as it did so. Keeping the trigger pressed enabled the gun to continue firing until the belt was expended. The Maxim gun, as it became known, was adopted by almost every army within the decade, and was to remain in service for nearly fifty years. Maxim himself joined forces with the large British armaments firm of Vickers, and the Vickers machine gun, which served the British Army during two world wars, was merely a refined version of the Maxim gun.
    Maxim's interests continued to occupy several fields of technology, including flight. In 1891 he took out a patent for a steam-powered aeroplane fitted with a pendulous gyroscopic stabilizer which would maintain the pitch of the aeroplane at any desired inclination (basically, a simple autopilot). Maxim decided to test the relationship between power, thrust and lift before moving on to stability and control. He designed a lightweight steam-engine which developed 180 hp (135 kW) and drove a propeller measuring 17 ft 10 in. (5.44 m) in diameter. He fitted two of these engines into his huge flying machine testrig, which needed a wing span of 104 ft (31.7 m) to generate enough lift to overcome a total weight of 4 tons. The machine was not designed for free flight, but ran on one set of rails with a second set to prevent it rising more than about 2 ft (61 cm). At Baldwyn's Park in Kent on 31 July 1894 the huge machine, carrying Maxim and his crew, reached a speed of 42 mph (67.6 km/h) and lifted off its rails. Unfortunately, one of the restraining axles broke and the machine was extensively damaged. Although it was subsequently repaired and further trials carried out, these experiments were very expensive. Maxim eventually abandoned the flying machine and did not develop his idea for a stabilizer, turning instead to other projects. At the age of almost 70 he returned to the problems of flight and designed a biplane with a petrol engine: it was built in 1910 but never left the ground.
    In all, Maxim registered 122 US and 149 British patents on objects ranging from mousetraps to automatic spindles. Included among them was a 1901 patent for a foot-operated suction cleaner. In 1900 he became a British subject and he was knighted the following year. He remained a larger-than-life figure, both physically and in character, until the end of his life.

  • 119 Murdock (Murdoch), William

    [br]
    b. 21 August 1754 Cumnock, Ayrshire, Scotland
    d. 15 November 1839 Handsworth, Birmingham, England
    [br]
    Scottish engineer and inventor, pioneer in coal-gas production.
    [br]
    He was the third child and the eldest of three boys born to John Murdoch and Anna Bruce. His father, a millwright and joiner, spelled his name Murdock on moving to England. He was educated for some years at Old Cumnock Parish School and in 1777, with his father, he built a "wooden horse", supposed to have been a form of cycle. In 1777 he set out for the Soho manufactory of Boulton \& Watt, where he quickly found employment, Boulton supposedly being impressed by the lad's hat. This was oval and made of wood, and young William had turned it himself on a lathe of his own manufacture. Murdock quickly became Boulton \& Watt's representative in Cornwall, where there was a flourishing demand for steam-engines. He lived at Redruth during this period.
    It is said that a number of the inventions generally ascribed to James Watt are in fact as much due to Murdock as to Watt. Examples are the piston and slide valve and the sun-and-planet gearing. A number of other inventions are attributed to Murdock alone: typical of these is the oscillating cylinder engine which obviated the need for an overhead beam.
    In about 1784 he planned a steam-driven road carriage of which he made a working model. He also planned a high-pressure non-condensing engine. The model carriage was demonstrated before Murdock's friends and travelled at a speed of 6–8 mph (10–13 km/h). Boulton and Watt were both antagonistic to their employees' developing independent inventions, and when in 1786 Murdock set out with his model for the Patent Office, having received no reply to a letter he had sent to Watt, Boulton intercepted him on the open road near Exeter and dissuaded him from going any further.
    In 1785 he married Mary Painter, daughter of a mine captain. She bore him four children, two of whom died in infancy, those surviving eventually joining their father at the Soho Works. Murdock was a great believer in pneumatic power: he had a pneumatic bell-push at Sycamore House, his home near Soho. The pattern-makers lathe at the Soho Works worked for thirty-five years from an air motor. He also conceived the idea of a vacuum piston engine to exhaust a pipe, later developed by the London Pneumatic Despatch Company's railway and the forerunner of the atmospheric railway.
    Another field in which Murdock was a pioneer was the gas industry. In 1791, in Redruth, he was experimenting with different feedstocks in his home-cum-office in Cross Street: of wood, peat and coal, he preferred the last. He designed and built in the backyard of his house a prototype generator, washer, storage and distribution plant, and publicized the efficiency of coal gas as an illuminant by using it to light his own home. In 1794 or 1795 he informed Boulton and Watt of his experimental work and of its success, suggesting that a patent should be applied for. James Watt Junior was now in the firm and was against patenting the idea since they had had so much trouble with previous patents and had been involved in so much litigation. He refused Murdock's request and for a short time Murdock left the firm to go home to his father's mill. Boulton \& Watt soon recognized the loss of a valuable servant and, in a short time, he was again employed at Soho, now as Engineer and Superintendent at the increased salary of £300 per year plus a 1 per cent commission. From this income, he left £14,000 when he died in 1839.
    In 1798 the workshops of Boulton and Watt were permanently lit by gas, starting with the foundry building. The 180 ft (55 m) façade of the Soho works was illuminated by gas for the Peace of Paris in June 1814. By 1804, Murdock had brought his apparatus to a point where Boulton \& Watt were able to canvas for orders. Murdock continued with the company after the death of James Watt in 1819, but retired in 1830 and continued to live at Sycamore House, Handsworth, near Birmingham.

  • 120 Murray, Matthew

    [br]
    b. 1765 near Newcastle upon Tyne, England
    d. 20 February 1826 Holbeck, Leeds, England
    [br]
    English mechanical engineer and steam engine, locomotive and machine-tool pioneer.
    [br]
    Matthew Murray was apprenticed at the age of 14 to a blacksmith who probably also did millwrighting work. He then worked as a journeyman mechanic at Stockton-on-Tees, where he had experience with machinery for a flax mill at Darlington. Trade in the Stockton area became slack in 1788 and Murray sought work in Leeds, where he was employed by John Marshall, who owned a flax mill at Adel, located about 5 miles (8 km) from Leeds. He soon became Marshall's chief mechanic, and when in 1790 a new mill was built in the Holbeck district of Leeds by Marshall and his partner Benyon, Murray was responsible for the installation of the machinery. At about this time he took out two patents relating to improvements in textile machinery.
    In 1795 he left Marshall's employment and, in partnership with David Wood (1761– 1820), established a general engineering and millwrighting business at Mill Green, Holbeck. In the following year the firm moved to a larger site at Water Lane, Holbeck, and additional capital was provided by two new partners, James Fenton (1754–1834) and William Lister (1796–1811). Lister was a sleeping partner and the firm was known as Fenton, Murray \& Wood and was organized so that Fenton kept the accounts, Wood was the administrator and took charge of the workshops, while Murray provided the technical expertise. The factory was extended in 1802 by the construction of a fitting shop of circular form, after which the establishment became known as the "Round Foundry".
    In addition to textile machinery, the firm soon began the manufacture of machine tools and steam-engines. In this field it became a serious rival to Boulton \& Watt, who privately acknowledged Murray's superior craftsmanship, particularly in foundry work, and resorted to some industrial espionage to discover details of his techniques. Murray obtained patents for improvements in steam engines in 1799, 1801 and 1802. These included automatic regulation of draught, a mechanical stoker and his short-D slide valve. The patent of 1801 was successfully opposed by Boulton \& Watt. An important contribution of Murray to the development of the steam engine was the use of a bedplate so that the engine became a compact, self-contained unit instead of separate components built into an en-gine-house.
    Murray was one of the first, if not the very first, to build machine tools for sale. However, this was not the case with the planing machine, which he is said to have invented to produce flat surfaces for his slide valves. Rather than being patented, this machine was kept secret, although it was apparently in use before 1814.
    In 1812 Murray was engaged by John Blenkinsop (1783–1831) to build locomotives for his rack railway from Middleton Colliery to Leeds (about 3 1/2 miles or 5.6 km). Murray was responsible for their design and they were fitted with two double-acting cylinders and cranks at right angles, an important step in the development of the steam locomotive. About six of these locomotives were built for the Middleton and other colliery railways and some were in use for over twenty years. Murray also supplied engines for many early steamboats. In addition, he built some hydraulic machinery and in 1814 patented a hydraulic press for baling cloth.
    Murray's son-in-law, Richard Jackson, later became a partner in the firm, which was then styled Fenton, Murray \& Jackson. The firm went out of business in 1843.
