  • 81 Ferguson, Peter Jack

    SUBJECT AREA: Ports and shipping
    [br]
    b. 21 July 1840 Partick, near Glasgow, Scotland
    d. 17 March 1911 Greenock, Scotland
    [br]
    Scottish marine engineer, pioneer of multiple-expansion steam reciprocating machinery.
    [br]
    Ferguson was educated at the High School of Glasgow before going on to serve his apprenticeship in the engineering department of Thomas Wingate's shipyard. This yard, situated at Whiteinch, then just outside the Glasgow boundary, built interesting and innovative craft and had a tradition of supplying marine engines that were at the leading edge of technology. On his appointment as Manager, Ferguson designed several new types of engines, and in 1872 he was responsible for the construction of what is claimed to be the world's first triple-expansion engine, predating the machinery on SS Propontis by two years and Napier's masterpiece, the SS Aberdeen, by nine years. In 1885, along with others, he founded the shipyard of Fleming and Ferguson, of Paisley, which in the subsequent eighty-five years was to build nearly seven hundred ships. From the outset they built advanced steam reciprocating machinery as well as dredging and other types of plant. The new shipyard was to benefit from Ferguson's experience and from the inspiration he had gained in Wingate's, where experimentation was the norm.

  • 82 Ferranti, Sebastian Ziani de

    [br]
    b. 9 April 1864 Liverpool, England
    d. 13 January 1930 Zurich, Switzerland
    [br]
    English manufacturing engineer and inventor, a pioneer and early advocate of high-voltage alternating-current electric-power systems.
    [br]
    Ferranti, who had taken an interest in electrical and mechanical devices from an early age, was educated at St Augustine's College in Ramsgate and for a short time attended evening classes at University College, London. Rather than pursue an academic career, Ferranti, who had intense practical interests, found employment in 1881 with the Siemens Company (see Werner von Siemens) in their experimental department. There he had the opportunity to superintend the installation of electric-lighting plants in various parts of the country. Becoming acquainted with Alfred Thomson, an engineer, Ferranti entered into a short-lived partnership with him to manufacture the Ferranti alternator. This generator, with a unique zig-zag armature, had an efficiency exceeding that of all its rivals. Finding that Sir William Thomson had invented a similar machine, Ferranti formed a company with him to combine the inventions and produce the Ferranti- Thomson machine. For this the Hammond Electric Light and Power Company obtained the sole selling rights.
    In 1885 the Grosvenor Gallery Electricity Supply Corporation was having serious problems with its Gaulard and Gibbs series distribution system. Ferranti, when consulted, reviewed the design and recommended transformers connected across constant-potential mains. In the following year, at the age of 22, he was appointed Engineer to the company and introduced the pattern of electricity supply that was eventually adopted universally. Ambitious plans by Ferranti for London envisaged the location of a generating station of unprecedented size at Deptford, about eight miles (13 km) from the city, a departure from the previous practice of placing stations within the area to be supplied. For this venture the London Electricity Supply Corporation was formed. Ferranti's bold decision to bring the supply from Deptford at the hitherto unheard-of pressure of 10,000 volts required him to design suitable cables, transformers and generators. Ferranti planned generators with 10,000 hp (7,460 kW)engines, but these were abandoned at an advanced stage of construction. Financial difficulties were caused in part when a Board of Trade enquiry in 1889 reduced the area that the company was able to supply. In spite of this adverse situation the enterprise continued on a reduced scale. Leaving the London Electricity Supply Corporation in 1892, Ferranti again started his own business, manufacturing electrical plant. He conceived the use of wax-impregnated paper-insulated cables for high voltages, which formed a landmark in the history of cable development. This method of flexible-cable manufacture was used almost exclusively until synthetic materials became available. In 1892 Ferranti obtained a patent which set out the advantages to be gained by adopting sector-shaped conductors in multi-core cables. This was to be fundamental to the future design and development of such cables.
    A total of 176 patents were taken out by S.Z. de Ferranti. His varied and numerous inventions included a successful mercury-motor energy meter and improvements to textile-yarn produc-tion. A transmission-line phenomenon where the open-circuit voltage at the receiving end of a long line is greater than the sending voltage was named the Ferranti Effect after him.

  • 83 Holland, John Philip

    SUBJECT AREA: Ports and shipping
    [br]
    b. 29 February 1840 Liscanor, Co. Clare, Ireland
    d. 12 August 1915 Newark, New Jersey, USA
    [br]
    Irish/American inventor of the successful modern submarine
    [br]
    Holland was educated first in his native town and later in Limerick, a seaport bustling with coastal trade ships. His first job was that of schoolteacher, and as such he worked in various parts of Ireland until he was about 32 years old. A combination of his burning patriotic zeal for Ireland and his interest in undersea technology (then in its infancy) made him consider designs for underwater warships for use against the British Royal Navy in the fight for Irish independence. He studied all known works on the subject and commenced drawing plans, but he was unable to make real headway owing to a lack of finance.
    In 1873 he travelled to the United States, ultimately settling in New Jersey and continuing in the profession of teaching. His work on submarine design continued, but in 1875 he suffered a grave setback when the United States Navy turned down his designs. Help came from an unexpected source, the Irish Republican Brotherhood, or Fenian Society, which had been founded in Dublin and New York in 1858. Financial help enabled Holland to build a 4 m (13 ft) one-person craft, which was tested in 1878, and then a larger boat of 19 tonnes' displacement that was tested with a crew of three to depths of 20 m (65 ft) in New York's harbour in 1883. Known as the Fenian Ram, it embodied most of the principles of modern submarines, including weight compensation. The Fenians commandeered this boat, but they were unable to operate it satisfactorily and it was relegated to history.
    Holland continued work, at times independently and sometimes with others, and continuously advocated submarines to the United States Navy. In 1895 he was successful in winning a contract for US$150,000 to build the US Submarine Plunger at Baltimore. With too much outside interference, this proved an unsatisfactory venture. However, with only US$5,000 of his capital left, Holland started again and in 1898 he launched the Holland at Elizabeth, New Jersey. This 16 m (52 ft) vessel was successful, and in 1900 it was purchased by the United States Government.
    Six more boats were ordered by the Americans, and then some by the Russians and the Japanese. The British Royal Navy ordered five, which were built by Vickers Son and Maxim (now VSEL) at Barrow-in-Furness in the years up to 1903, commencing their long run of submarine building. They were licensed by another well-known name, the Electric Boat Company, which had formerly been the J.P.Holland Torpedo Boat Company.
    Holland now had some wealth and was well known. He continued to work, trying his hand at aeronautical research, and in 1904 he invented a respirator for use in submarine rescue work. It is pleasing to record that one of his ships can be seen to this day at the Royal Navy Submarine Museum, Gosport: HM Submarine Holland No. 1, which was lost under tow in 1913 but salvaged and restored in the 1980s.

    Ives gained his PhD in physics from Johns Hopkins University, Baltimore, Maryland, and subsequently served in the US Signal Corps, eventually gaining experience in aerial photography. He then joined the Western Electric Engineering Department (later Bell Telephone Laboratories), c.1920 becoming leader of a group concerned with television-image transmission over telephone lines. In 1927, using a Nipkow disc, he demonstrated 50-line, 18 frames/sec pictures that could be displayed as either 2 in.×2 1/2 in. (5.1 cm×6.4 cm) images suitable for a "wirephone", or 2 ft ×2 1/2 ft (61 cm×76 cm) images for television viewing. Two years later, using a single-spiral disc and three separately modulated light sources, he was able to produce full-colour images.

    Kemeny entered the USA as an immigrant in 1939. He subsequently became a mathematics lecturer at Dartmouth College, Hanover, New Hampshire, and later became a professor and then Chairman of the Mathematics Department; finally, in 1971, he became President of the College. In 1964, with Thomas Kurtz, he developed the high-level computer language known as BASIC (Beginners All-purpose Symbolic Instruction Code). It was initially designed for use by students with a time-sharing minicomputer, but it soon became the standard language for microcomputers, frequently being embedded in the computer as "firmware" loaded into a read-only-memory (ROM) integrated circuit.

  • 87 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.

  • 88 McKay, Hugh Victor

    [br]
    b. c. 1866 Drummartin, Victoria, Australia
    d. 21 May 1926 Australia
    [br]
    Australian inventor and manufacturer of harvesting and other agricultural equipment.
    [br]
    A farmer's son, at the age of 17 McKay developed modifications to the existing stripper harvester and created a machine that would not only strip the seed from standing corn, but was able to produce a threshed, winnowed and clean sample in one operation. The prototype was produced in 1884 and worked well on the two acres of wheat that had been set aside on the family farm. By arrangement with a Melbourne plough maker, five machines were made and sold for the 1885 season. In 1886 the McKay Harvester Company was formed, with offices at Ballarat, from which the machines, built by various companies, were sold. The business expanded quickly, selling sixty machines in 1888, and eventually rising to the production of nearly 2,000 harvesters in 1905. The name "Sunshine" was given to the harvester, and the "Sun" prefix was to appear on all other implements produced by the company as it diversified its production interests. In 1902 severe drought reduced machinery sales and left 2,000 harvesters unsold. McKay was forced to look to export markets to dispose of his surplus machines. By 1914 a total of 10,000 machines were being exported annually. During the First World War McKay was appointed to the Business Board of the Defence Department. Increases in the scale of production resulted in the company moving to Melbourne, where it was close to the port of entry of raw materials and was able to export the finished article more readily. In 1909 McKay produced one of the first gas-engined harvesters, but its cost prevented it from being more than an experimental prototype. By this time McKay was the largest agricultural machinery manufacturer in the Southern hemisphere, producing a wide range of implements, including binders. In 1916 McKay hired Headlie Taylor, who had developed a machine capable of harvesting fallen crops. The jointly developed machine was a major success, coming as it did in what would otherwise have been a disastrous Australian harvest. Further developments included the "Sun Auto-header" in 1923, the first of the harvesting machines to adopt the "T" configuration to be seen on modern harvesters. The Australian market was expanding fast and a keen rivalry developed between McKay and Massey Harris. Confronted by the tariff regulations with which the Australian Government had protected its indigenous machinery industry since 1906, Massey Harris sold all its Australian assets to the H.V. McKay company in 1930. Twenty-three years later Massey Ferguson acquired the old Sunshine works and was still operating from there in the 1990s.
    Despite a long-running history of wage disputes with his workforce, McKay established a retiring fund as well as a self-help fund for distressed cases. Before his death he created a charitable trust and requested that some funds should be made available for the "aerial experiments" which were to lead to the establishment of the Flying Doctor Service.

    b. 23 November 1851 Plainville, Connecticut, USA
    d. 27 October 1942 Plainville, Connecticut, USA
    [br]
    American mechanical engineer and machine-tool designer.
    [br]
    After an elementary education at the public schools of Plainville and Thomaston, Connecticut, Charles H.Norton started work in 1866 at the Seth Thomas Clock Company in Thomaston. He was soon promoted to machinist, and further progress led to his successive appointments as Foreman, Superintendent of Machinery and Manager of the department making tower clocks. He designed many public clocks.
    In 1886 he obtained a position as Assistant Engineer with the Brown \& Sharpe Manufacturing Company at Providence, Rhode Island, and was engaged in redesigning their universal grinding machine to give it more rigidity and make it more suitable for use as a production machine. In 1890 he left to become a partner in a newly established firm, Leland, Faulconer \& Norton Company at Detroit, Michigan, designing and building machine tools. He withdrew from this firm in 1895 and practised as a consulting mechanical engineer for a short time before returning to Brown \& Sharpe in 1896. There he designed a grinding machine incorporating larger and wider grinding wheels so that heavier cuts could be made to meet the needs of the mass-production industries, especially the automobile industry. This required a heavier and more rigid machine and greater power, but these ideas were not welcomed at Brown \& Sharpe and in 1900 Norton left to found the Norton Grinding Company in Worcester, Massachusetts. Here he was able to develop heavy-production grinding machines, including special machines for grinding crank-shafts and camshafts for the automobile industry.
    In setting up the Norton Grinding Company, Charles H.Norton received financial support from members of the Norton Emery Wheel Company (also of Worcester and known after 1906 as the Norton Company), but he was not related to the founder of that company. The two firms were completely independent until 1919 when they were merged. From that time Charles H.Norton served as Chief Engineer of the machinery division of the Norton Company, until 1934 when he became their Consulting Engineer.

    b. 29 August 1830 Thompson, Connecticut, USA
    d. 31 July 1901 Hartford, Connecticut, USA
    [br]
    American mechanical engineer and inventor.
    [br]
    Little is known of the early training of Edward G. Parkhurst, but at the time of Civil War (1861–5) he was employed by the Savage Arms Company of Middletown, Connecticut. In 1869 he joined the Pratt \& Whitney Company of Hartford, Connecticut, as Assistant Superintendent and later took charge of their gun department. He was the inventor of many improvements in machine tools and armaments. Among these was an automatic rod feeder for turret lathes, in which movement of a single lever enabled bar stock to be fed through the lathe spindle and gripped by a collet chuck while the machine was in motion. This was patented in August 1871 and was followed by other patents, particularly for improvements in machine guns and their accessories. Parkhurst retired from Pratt \& Whitney c. 1895 but was afterwards associated with the American Ordnance Company and the Bethlehem Steel Company. He was a founder member of the American Society of Mechanical Engineers in 1880 and served his home city of Hartford as Councillor and Alderman. In 1900 he contributed to the journal American Machinist some articles of reminiscences dealing with the early history of the American machine-tool industry and, in particular, the earliest milling machines and the origin of the turret lathe.

    b. 3 September 1875 Maffersdorf, Austria
    d. 30 January 1952 Stuttgart, Baden-Württemberg, Germany
    [br]
    Austrian automobile engineer, designer of the Volkswagen car.
    [br]
    At the age of fifteen, Porsche built a complete electrical installation for his home. In 1894 he went to technical school in Vienna. Four years later he became Manager of the test department of the Bela Egger concern, which later became part of the Brown Boveri organization where he became the first Assistant in the calculating section. In 1899 he joined the long-established coachbuilders Jacob Lohner, and in 1902 a car of his design with mixed drive won the 1,000 kg (2,200 lb) class in the Exelberg races. In 1905 he joined the Austro-Daimler Company as Technical Director; his subsequent designs included an 85 hp mixed-drive racing car in 1907 and in 1912 an air-cooled aircraft engine which came to be known in later years as the "great-grandfather" of the Volkswagen engine. In 1916, he became Managing Director of Austro-Daimler.
    In 1921 he designed his first small car, which, appearing under the name of Sasch, won its class in the 1922 Targa Florio, a gruelling road-race in Italy. In 1923 Porsche left Austro-Daimler and joined the Daimler Company in Untertürk-heim, near Stuttgart, Germany. In 1929 he joined the firm of Steyr in Austria as a director and chief engineer, and in 1930 he set up his own independent design office in Stuttgart. In 1932 he visited Russia, and in the same year completed the design calculations for the Auto-Union racing car.
    In 1934, with his son Ferry (b. 1909), he prepared a plan for the construction of the German "people's car", a project initiated by Adolf Hitler and his Nazi regime; in June of that year he signed a contract for the design work on the Volkswagen. Racing cars of his design were also successful in 1934: the rear-engined Auto-Union won the German Grand Prix, and another Au to-Union car took the Flying Kilometre speed record at 327 km/h (203.2 mph). In 1935 Daimler-Benz started preproduction on the Volkswagen. The first trials of the cars took place in the autumn of 1936, and the following year thirty experimental cars were built by Daimler-Benz. In that year, Porsche visited the United States, where he met Henry Ford; in October an Auto-Union took the Flying Five Kilometre record at 404.3 km/h (251.2 mph). On 26 May 1938, the foundation stone of the Volkswagen factory was laid in Wolfsburg, near Braunschweig, Germany.
    In October 1945 Ferdinand Porsche was arrested by a unit of the United States Army and taken to Hessen; the French army removed him to Baden-Baden, then to Paris and later to Dijon. During this time he was consulted by Renault engineers regarding the design of their 4CV and designed a diesel-engined tractor. He was finally released on 5 August 1947. His last major work before his death was the approval of the design for the Cisitalia Grand Prix car.

    [br]
    b. 23 November 1869 Copenhagen, Denmark
    d. 23 July 1942 Gentofte, Denmark
    [br]
    Danish engineer who developed practical magnetic recording and the arc generator for continuous radio waves.
    [br]
    From an early age he was absorbed by phenomena of physics to the exclusion of all other subjects, including mathematics. When choosing his subjects for the final three years in Borgedydskolen in Christianshavn (Copenhagen) before university, he opted for languages and history. At the University of Copenhagen he embarked on the study of medicine in 1889, but broke it off and was apprenticed to the machine firm of A/S Frichs Eftf. in Aarhus. He was employed between 1893 and 1899 as a mechanic and assistant in the laboratory of the Copenhagen Telephone Company KTAS. Eventually he advanced to be Head of the line fault department. This suited his desire for experiment and measurement perfectly. After the invention of the telegraphone in 1898, he left the laboratory and with responsible business people he created Aktieselskabet Telegrafonen, Patent Poulsen in order to develop it further, together with Peder Oluf Pedersen (1874– 1941). Pedersen brought with him the mathematical background which eventually led to his professorship in electronic engineering in 1922.
    The telegraphone was the basis for multinational industrial endeavours after it was demonstrated at the 1900 World's Exhibition in Paris. It must be said that its strength was also its weakness, because the telegraphone was unique in bringing sound recording and reproduction to the telephone field, but the lack of electronic amplifiers delayed its use outside this and the dictation fields (where headphones could be used) until the 1920s. However, commercial interest was great enough to provoke a number of court cases concerning patent infringement, in which Poulsen frequently figured as a witness.
    In 1903–4 Poulsen and Pedersen developed the arc generator for continuous radio waves which was used worldwide for radio transmitters in competition with Marconi's spark-generating system. The inspiration for this work came from the research by William Duddell on the musical arc. Whereas Duddell had proposed the use of the oscillations generated in his electric arc for telegraphy in his 1901 UK patent, Poulsen contributed a chamber of hydrogen and a transverse magnetic field which increased the efficiency remarkably. He filed patent applications on these constructions from 1902 and the first publication in a scientific forum took place at the International Electrical Congress in St Louis, Missouri, in 1904.
    In order to use continuous waves efficiently (the high frequency constituted a carrier), Poulsen developed both a modulator for telegraphy and a detector for the carrier wave. The modulator was such that even the more primitive spark-communication receivers could be used. Later Poulsen and Pedersen developed frequency-shift keying.
    The Amalgamated Radio-Telegraph Company Ltd was launched in London in 1906, combining the developments of Poulsen and those of De Forest Wireless Telegraph Syndicate. Poulsen contributed his English and American patents. When this company was liquidated in 1908, its assets were taken over by Det Kontinentale Syndikat for Poulsen Radio Telegrafi, A/S in Copenhagen (liquidated 1930–1). Some of the patents had been sold to C.Lorenz AG in Berlin, which was very active.
    The arc transmitting system was in use worldwide from about 1910 to 1925, and the power increased from 12 kW to 1,000 kW. In 1921 an exceptional transmitter rated at 1,800 kW was erected on Java for communications with the Netherlands. More than one thousand installations had been in use worldwide. The competing systems were initially spark transmitters (Marconi) and later rotary converters ( Westinghouse). Similar power was available from valve transmitters only much later.
    From c. 1912 Poulsen did not contribute actively to further development. He led a life as a well-respected engineer and scientist and served on several committees. He had his private laboratory and made experiments in the composition of matter and certain resonance phenomena; however, nothing was published. It has recently been suggested that Poulsen could not have been unaware of Oberlin Smith's work and publication in 1888, but his extreme honesty in technical matters indicates that his development was indeed independent. In the case of the arc generator, Poulsen was always extremely frank about the inspiration he gained from earlier developers' work.

    [br]
    English engineer and educator.
    [br]
    Osborne Reynolds's father, a clergyman and schoolteacher, had been a Fellow of Queens' College, Cambridge; it was to Queens' that the young Reynolds went to study mathematics, graduating as 7th Wrangler in 1867, and going on in his turn to become a Fellow of the College. Reynolds had developed an interest in practical applications of physics and engineering, and for a short time he entered the office of the London civil engineers Lawson and Mansergh. In 1868 he was appointed to the new Chair of Engineering at Owens College, Manchester, and he remained in this post for thirty-seven years, until he retired in 1905. During this period he presided over a department that grew steadily in size and reputation, and undertook prolonged research projects into phenomena such as lubrication, the laws governing the flow of water in pipes, turbulence and other physical features with practical applications. He was elected a Fellow of the Royal Society in 1877, being nominated Royal Medallist in 1888. In 1883 he became a Member of the Institution of Civil Engineers, and in 1885 he was awarded the Telford Premium of the Institution. He served as Secretary of the Manchester Literary and Philosophical Society from 1874 to 1883, and was appointed President in 1888–9 and Dalton Medallist in 1903. He was President of Section G of the British Association for the History of Science in 1887, and in 1884 he received the degree of LLD from Glasgow University. Among his many students at Owens College was J.J. (later Sir Joseph) Thomson (1856–1940), who entered the college in 1871. Reynolds's collected scientific papers were published in 1900–3.

    d. 17 August 1865 Budapest, Austro-Hungary
    [br]
    Hungarian physician whose regime of chemical cleansing of the hands radically reduced the mortality associated with puerperal sepsis.
    [br]
    Originally a law student, he abandoned that discipline for medicine and graduated at Vienna in 1844. He was immediately appointed Assistant Professor in the midwifery department under Johann Klein. At this time there was a maternal mortality rate from sepsis of not less than 16 per cent in the students' wards, although the rate was not as high in the midwives' wards. The death of a colleague from a dissection wound led Semmelweis to associate the infection in the lying-in wards with inadequate cleaning of the hands of doctors who went straight from the dissecting room to attend deliveries.
    In 1847 he instituted a regime of hand washing with chlorinated lime water, and by the end of the year the mortality in the students' ward had fallen to 1 per cent, less than that in the midwives' ward. However, Klein refused to accept the implications of these findings, and Semmelweis was dismissed from Vienna in 1849.
    He was able to obtain a further post in Budapest in 1850, and during the ensuing six years he effected a similar reduction in puerperal mortality by the same methods. Of an impatient and irascible character, in 1865 he was committed to a mental institution, dying shortly afterwards from septicaemia arising in a dissection wound suffered before his admission.

    SUBJECT AREA: Ports and shipping
    [br]
    b. 11 December 1767 near Fakenham, Norfolk, England
    d. 25 April 1840 Taunton, Somerset, England
    [br]
    English naval architect who as Surveyor to the Royal Navy made fundamental improvements in wooden ship construction.
    [br]
    After the death of his father, Seppings at the age of 14 moved to his uncle's home in Plymouth, where shortly after (1782) he was apprenticed to the Master Shipwright. His indentures were honoured fully by 1789 and he commenced his climb up the professional ladder of the ship construction department of the Royal Dockyards. In 1797 he became Assistant Master Shipwright at Plymouth, and in 1804 he was appointed Master Shipwright at Chatham. In 1813 Sir William Rule, Surveyor to the Navy, retired and the number of surveyors was increased to three, with Seppings being appointed the junior. Later he was to become Surveyor to the Royal Navy, a post he held until his retirement in 1832. Seppings introduced many changes to ship construction in the early part of the nineteenth century. It is likely that the introduction of these innovations required positive and confident management, and their acceptance tells us much about Seppings. The best-known changes were the round bow and stern in men-of-war and the alteration to framing systems.
    The Seppings form of diagonal bracing ensured that wooden ships, which are notorious for hogging (i.e. drooping at the bow and stern), were stronger and therefore able to be built with greater length. This change was complemented by modifications to the floors, frames and futtocks (analogous to the ribs of a ship). These developments were to be taken further once iron composite construction (wooden sheathing on iron frames) was adopted in the United Kingdom mid-century.

    Principal Honours and Distinctions
    FRS. Knighted (by the Prince Regent aboard the warship Royal George) 1819.
    Bibliography
    Throughout his life Seppings produced a handful of pamphlets and published letters, as well as two papers that were published in the Philosophical Transactions of the Royal Society (1814 and 1820).

    d. 25 January 1963 Willesden, London, England
    [br]
    Russian engineer and friend of Vladimir Zworykin; Director of Research at EMI, responsible for creating the team that successfully developed the world's first all-electronic television system.
    [br]
    After his initial engineering education at Kiev Polytechnic, Shoenberg went to London to undertake further studies at the Royal College of Science. In 1905 he returned to Russia and rose to become Chief Engineer of the Russian Wireless Telegraphy Company. He then returned to England, where he was a consultant in charge of the Patent Department and then joint General Manager of the Marconi Wireless Telegraphy Company (see Marconi). In 1929 he joined the Columbia Graphophone Company, but two years later this amalgamated with the Gramophone Company, by then known as His Master's voice (HMV), to form EMI (Electric and Musical Industries), a company in which the Radio Corporation of America (RCA) had a significant shareholding. Appointed Director of the new company's Research Laboratories in 1931, Shoenberg gathered together a team of highly skilled engineers, including Blumlein, Browne, Willans, McGee, Lubszynski, Broadway and White, with the objective of producing an all-electronic television system suitable for public broadcasting. A 150-line system had already been demonstrated using film as the source material; a photoemissive camera tube similar to Zworykin's iconoscope soon followed. With alternate demonstrations of the EMI system and the mechanical system of Baird arranged with the object of selecting a broadcast system for the UK, Shoenberg took the bold decision to aim for a 405-line "high-definition" standard, using interlaced scanning based on an RCA patent and further developed by Blumlein. This was so successful that it was formally adopted as the British standard in 1935 and regular broadcasts, the first in the world, began in 1937. It is a tribute to Shoenberg's vision and the skills of his team that this standard was to remain in use, apart from the war years, until finally superseded in 1985.

    b. 1745
    d. 14 March 1827 Hardon Grange, Bingley, Yorkshire, England.
    [br]
    English army officer and military engineer.
    [br]
    William Twiss entered the Ordnance Department at the age of 15, and in 1762, aged 17, he was appointed Overseer of Works at Gibraltar. At the end of the Seven Years War, in 1763, he was commissioned Ensign in the Engineers, and further promotion followed while he still remained in Gibraltar. In 1771, as a Lieutenant, he returned to England to be employed on Port-smouth's dockyard fortifications. In 1776 he was posted to Canada, where he was soon appointed Controller of Works for the building of a British fleet for Lake Champlain. He was involved in military operations in the American War of Independence and in 1777 was present at the capture of Fort Ticonderoga (New York State). He was taken prisoner shortly afterwards, but was soon exchanged, and a year later he was promoted Captain.
    In 1779 he was given the task of constructing a short canal at Coteau du Lac, Quebec, to bypass rough water at this point in the St Lawrence River between Montreal and Pointe Maligne. This was probably the first locked canal in North America. In 1781, following his appointment as Chief Engineer for all military works in Canada, he supervised further navigational improvements on the St Lawrence with canals at Les Cèdres and the Cascades. In parallel with these projects, he was responsible for an amazing variety of works in Canada, including hospitals, windmills, store-houses, barracks, fortifications, roads, bridges, prisons, ironworks and dams. He was also responsible for a temporary citadel in Quebec.
    In 1783 he returned to England, and from 1794–1810 he served as Lieutenant- Governor of the Royal Military Academy at Woolwich, although in 1799 he was sent to Holland as Commanding Engineer to the Duke of York. In 1802 he was promoted Colonel and was in Ireland reporting on the defences there. He became Colonel Commandant, Royal Engineers, in 1809, and retired two years later. In retirement he was promoted Lieu tenant-General in 1812 and General in 1825.
