  • 1 scenario planning

    Gen Mgt
    a technique that requires the use of a scenario in the process of strategic planning to aid the development of corporate strategy in the face of uncertainty about the future. Scenario planning was developed in a military context during the 1940s. Its use in a business context was pioneered at Royal Dutch Shell during the 1960s and increased after the 1972 oil crisis. The process of identifying alternative scenarios of the future, based on a variety of differing assumptions, can help managers anticipate changes in the business environment and raise awareness of the frame of reference within which they are operating. The scenarios are then used to assist in both the development of strategies for dealing with unexpected events and the choice between alternative strategic options.

  • 2 short-interval scheduling

    Ops
    a technique for assigning a planned quantity of work to a workstation, to be completed in a specific time. Short-interval scheduling was pioneered during the 1930s by large mailorder houses in the United States and was widely used in the 1950s to provide greater control of routine and semi-routine processes through regular checks of individual performance over short spans of time. Shortinterval scheduling enables productivity to be improved, as all delays can be identified and corrected at an early stage.

  • 7 Six Sigma

    Ops
    a data-driven method for achieving near perfect quality. Sigma is the Greek letter used to denote standard deviation, or measure of variation from the mean, which in production terms is used to imply defect. The greater the number of sigmas, the fewer the defects. In true Six Sigma environments, companies operate at a quality level of six standard deviations from the mean, or at a defect level of 3.4 per million. Six Sigma analysis can be focused upon any part of production or service activities, and has a strong emphasis on statistical analysis in design, manufacturing, and customer-oriented activities. It is based on statistical tools and techniques of quality management developed by Joseph Juran. It was pioneered in the United States by Motorola, and subsequently became much more popular in the 1990s after its adoption by General Electric under Jack Welch.

  • 8 Bakewell, Robert

    [br]
    b. 23 May 1725 Loughborough, England
    d. 1 October 1795 Loughborough, England
    [br]
    English livestock breeder who pioneered the practice of progeny testing for selecting breeding stock; he is particularly associated with the development of the Improved Leicester breed of sheep.
    [br]
    Robert Bakewell was the son of the tenant farming the 500-acre (200 hectare) Dishley Grange Farm, near Loughborough, where he was born. The family was sufficiently wealthy to allow Robert to travel, which he began to do at an early age, exploring the farming methods of the West Country, Norfolk, Ireland and Holland. On taking over the farm he continued the development of the irrigation scheme begun by his father. Arthur Young visited the farm during his tour of east England in 1771. At that time it consisted of 440 acres (178 hectares), 110 acres (45 hectares) of which were arable, and carried a stock of 60 horses, 400 sheep and 150 other assorted beasts. Of the arable land, 30 acres (12 hectares) were under root crops, mainly turnips.
    Bakewell was not the first to pioneer selective breeding, but he was the first successfully to apply selection to both the efficiency with which an animal utilized its food, and its physical appearance. He always had a clear idea of the animal he wanted, travelled extensively to collect a range of animals possessing the characteristics he sought, and then bred from these towards his goal. He was aware of the dangers of inbreeding, but would often use it to gain the qualities he wanted. His early experiments were with Longhorn cattle, which he developed as a meat rather than a draught animal, but his most famous achievement was the development of the Improved Leicester breed of sheep. He set out to produce an animal that would put on the most meat in the least time and with the least feeding. As his base he chose the Old Leicester, but there is still doubt as to which other breeds he may have introduced to produce the desired results. The Improved Leicester was smaller than its ancestor, with poorer wool quality but with greatly improved meat-production capacity.
    Bakewell let out his sires to other farms and was therefore able to study their development under differing conditions. However, he made stringent rules for those who hired these animals, requiring the exclusive use of his rams on the farms concerned and requiring particular dietary conditions to be met. To achieve this control he established the Dishley Society in 1783. Although his policies led to accusations of closed access to his stock, they enabled him to keep a close control of all offspring. He thereby pioneered the process now recognized as "progeny testing".
    Bakewell's fame and that of his farm spread throughout the country and overseas. He engaged in an extensive correspondence and acted as host to all of influence in British and overseas agriculture, but it would appear that he was an over-generous host, since he is known to have been in financial difficulties in about 1789. He was saved from bankruptcy by a public subscription raised to allow him to continue with his breeding experiments; this experience may well have been the reason why he was such a staunch advocate of State funding of agricultural research.

  • 9 Merz, Charles Hesterman

    [br]
    b. 5 October 1874 Gateshead, England
    d. 14 October 1940 London, England
    [br]
    English engineer who pioneered large-scale integration of electricity-supply networks, which led to the inauguration of the British grid system.
    [br]
    Merz was educated at Bootham School in York and Armstrong College in Newcastle. He served an apprenticeship with the Newcastle Electric Supply Company at their first power station, Pandon Dene, and part of his training was at Robey and Company of Lincoln, steam engine builders, and the British Thomson-Houston Company, electrical equipment manufacturers. After working at Bankside in London and at Croydon, he became Manager of the Croydon supply undertaking. In 1898 he went to Cork on behalf of BTH to build and manage a tramway and electricity company. It was there that he met William McLellan, who later joined him in establishing a firm of consulting engineers. Merz, with his vision of large-scale electricity supply, pioneered an integrated traction and electricity scheme in north-eastern England. He was involved in the reorganization of electricity schemes in many countries and established a reputation as a leading parliamentary witness. Merz was appointed Director of Experiments and Research at the Admiralty, where his main contribution was the creation of an organization of outstanding engineers and scientists during the First World War. In 1925 he was largely responsible for a report of the Weir Committee which led to the Electricity (Supply) Act of 1926, the formation of the Central Electricity Board and the construction of the National Grid. The choice of 132 kV as the original grid voltage was that of Merz and his associates, as was the origin of the term "grid". Merz and his firm produced many technical innovations, including the first power-system control room and Merz-Price and Merz-Hunter forms of cable and transformer protection.

  • 14 Huygens, Christiaan

    SUBJECT AREA: Horology
    [br]
    b. 14 April 1629 The Hague, the Netherlands
    d. 8 June 1695 The Hague, the Netherlands
    [br]
    Dutch scientist who was responsible for two of the greatest advances in horology: the successful application of both the pendulum to the clock and the balance spring to the watch.
    [br]
    Huygens was born into a cultured and privileged class. His father, Constantijn, was a poet and statesman who had wide interests. Constantijn exerted a strong influence on his son, who was educated at home until he reached the age of 16. Christiaan studied law and mathematics at Ley den University from 1645 to 1647, and continued his studies at the Collegium Arausiacum in Breda until 1649. He then lived at The Hague, where he had the means to devote his time entirely to study. In 1666 he became a Member of the Académie des Sciences in Paris and settled there until his return to The Hague in 1681. He also had a close relationship with the Royal Society and visited London on three occasions, meeting Newton on his last visit in 1689. Huygens had a wide range of interests and made significant contributions in mathematics, astronomy, optics and mechanics. He also made technical advances in optical instruments and horology.
    Despite the efforts of Burgi there had been no significant improvement in the performance of ordinary clocks and watches from their inception to Huygens's time, as they were controlled by foliots or balances which had no natural period of oscillation. The pendulum appeared to offer a means of improvement as it had a natural period of oscillation that was almost independent of amplitude. Galileo Galilei had already pioneered the use of a freely suspended pendulum for timing events, but it was by no means obvious how it could be kept swinging and used to control a clock. Towards the end of his life Galileo described such a. mechanism to his son Vincenzio, who constructed a model after his father's death, although it was not completed when he himself died in 1642. This model appears to have been copied in Italy, but it had little influence on horology, partly because of the circumstances in which it was produced and possibly also because it differed radically from clocks of that period. The crucial event occurred on Christmas Day 1656 when Huygens, quite independently, succeeded in adapting an existing spring-driven table clock so that it was not only controlled by a pendulum but also kept it swinging. In the following year he was granted a privilege or patent for this clock, and several were made by the clockmaker Salomon Coster of The Hague. The use of the pendulum produced a dramatic improvement in timekeeping, reducing the daily error from minutes to seconds, but Huygens was aware that the pendulum was not truly isochronous. This error was magnified by the use of the existing verge escapement, which made the pendulum swing through a large arc. He overcame this defect very elegantly by fitting cheeks at the pendulum suspension point, progressively reducing the effective length of the pendulum as the amplitude increased. Initially the cheeks were shaped empirically, but he was later able to show that they should have a cycloidal shape. The cheeks were not adopted universally because they introduced other defects, and the problem was eventually solved more prosaically by way of new escapements which reduced the swing of the pendulum. Huygens's clocks had another innovatory feature: maintaining power, which kept the clock going while it was being wound.
    Pendulums could not be used for portable timepieces, which continued to use balances despite their deficiencies. Robert Hooke was probably the first to apply a spring to the balance, but his efforts were not successful. From his work on the pendulum Huygens was well aware of the conditions necessary for isochronism in a vibrating system, and in January 1675, with a flash of inspiration, he realized that this could be achieved by controlling the oscillations of the balance with a spiral spring, an arrangement that is still used in mechanical watches. The first model was made for Huygens in Paris by the clockmaker Isaac Thuret, who attempted to appropriate the invention and patent it himself. Huygens had for many years been trying unsuccessfully to adapt the pendulum clock for use at sea (in order to determine longitude), and he hoped that a balance-spring timekeeper might be better suited for this purpose. However, he was disillusioned as its timekeeping proved to be much more susceptible to changes in temperature than that of the pendulum clock.

  • 15 Paul, Robert William

    [br]
    b. 3 October 1869 Highbury, London, England
    d. 28 March 1943 London, England
    [br]
    English scientific instrument maker, inventor of the Unipivot electrical measuring instrument, and pioneer of cinematography.
    [br]
    Paul was educated at the City of London School and Finsbury Technical College. He worked first for a short time in the Bell Telephone Works in Antwerp, Belgium, and then in the electrical instrument shop of Elliott Brothers in the Strand until 1891, when he opened an instrument-making business at 44 Hatton Garden, London. He specialized in the design and manufacture of electrical instruments, including the Ayrton Mather galvanometer. In 1902, with a purpose-built factory, he began large batch production of his instruments. He also opened a factory in New York, where uncalibrated instruments from England were calibrated for American customers. In 1903 Paul introduced the Unipivot galvanometer, in which the coil was supported at the centre of gravity of the moving system on a single pivot. The pivotal friction was less than in a conventional instrument and could be used without accurate levelling, the sensitivity being far beyond that of any pivoted galvanometer then in existence.
    In 1894 Paul was asked by two entrepreneurs to make copies of Edison's kinetoscope, the pioneering peep-show moving-picture viewer, which had just arrived in London. Discovering that Edison had omitted to patent the machine in England, and observing that there was considerable demand for the machine from show-people, he began production, making six before the end of the year. Altogether, he made about sixty-six units, some of which were exported. Although Edison's machine was not patented, his films were certainly copyrighted, so Paul now needed a cinematographic camera to make new subjects for his customers. Early in 1895 he came into contact with Birt Acres, who was also working on the design of a movie camera. Acres's design was somewhat impractical, but Paul constructed a working model with which Acres filmed the Oxford and Cambridge Boat Race on 30 March, and the Derby at Epsom on 29 May. Paul was unhappy with the inefficient design, and developed a new intermittent mechanism based on the principle of the Maltese cross. Despite having signed a ten-year agreement with Paul, Acres split with him on 12 July 1895, after having unilaterally patented their original camera design on 27 May. By the early weeks of 1896, Paul had developed a projector mechanism that also used the Maltese cross and which he demonstrated at the Finsbury Technical College on 20 February 1896. His Theatrograph was intended for sale, and was shown in a number of venues in London during March, notably at the Alhambra Theatre in Leicester Square. There the renamed Animatographe was used to show, among other subjects, the Derby of 1896, which was won by the Prince of Wales's horse "Persimmon" and the film of which was shown the next day to enthusiastic crowds. The production of films turned out to be quite profitable: in the first year of the business, from March 1896, Paul made a net profit of £12,838 on a capital outlay of about £1,000. By the end of the year there were at least five shows running in London that were using Paul's projectors and screening films made by him or his staff.
    Paul played a major part in establishing the film business in England through his readiness to sell apparatus at a time when most of his rivals reserved their equipment for sole exploitation. He went on to become a leading producer of films, specializing in trick effects, many of which he pioneered. He was affectionately known in the trade as "Daddy Paul", truly considered to be the "father" of the British film industry. He continued to appreciate fully the possibilities of cinematography for scientific work, and in collaboration with Professor Silvanus P.Thompson films were made to illustrate various phenomena to students.
    Paul ended his involvement with film making in 1910 to concentrate on his instrument business; on his retirement in 1920, this was amalgamated with the Cambridge Instrument Company. In his will he left shares valued at over £100,000 to form the R.W.Paul Instrument Fund, to be administered by the Institution of Electrical Engineers, of which he had been a member since 1887. The fund was to provide instruments of an unusual nature to assist physical research.

    SUBJECT AREA: Aerospace
    [br]
    b. 21 December 1904 Billericay, England
    d. 24 May 1992 Little Shelford, Cambridge, England
    [br]
    English mechanical engineer, a pioneer in the modern phase of fuel-cell development.
    [br]
    After receiving his education at Eton and Trinity College, Cambridge, Bacon served with C.A. Parsons at Newcastle upon Tyne from 1925 to 1940. From 1946 to 1956 he carried out research on Hydrox fuel cells at Cambridge University and was a consultant on fuel-cell design to a number of organizations throughout the rest of his life.
    Sir William Grove was the first to observe that when oxygen and hydrogen were supplied to platinum electrodes immersed in sulphuric acid a current was produced in an external circuit, but he did not envisage this as a practical source of electrical energy. In the 1930s Bacon started work to develop a hydrogen-oxygen fuel cell that operated at moderate temperatures and pressures using an alkaline electrolyte. In 1940 he was appointed to a post at King's College, London, and there, with the support of the Admiralty, he started full-time experimental work on fuel cells. His brief was to produce a power source for the propulsion of submarines. The following year he was posted as a temporary experimental officer to the Anti-Submarine Experimental Establishment at Fairlie, Ayrshire, and he remained there until the end of the Second World War.
    In 1946 he joined the Department of Chemical Engineering at Cambridge, receiving a small amount of money from the Electrical Research Association. Backing came six years later from the National Research and Development Corporation (NRDC), the development of the fuel cell being transferred to Marshalls of Cambridge, where Bacon was appointed Consultant.
    By 1959, after almost twenty years of individual effort, he was able to demonstrate a 6 kW (8 hp) power unit capable of driving a small truck. Bacon appreciated that when substantial power was required over long periods the hydrogen-oxygen fuel cell associated with high-pressure gas storage would be more compact than conventional secondary batteries.
    The development of the fuel-cell system pioneered by Bacon was stimulated by a particular need for a compact, lightweight source of power in the United States space programme. Electro-chemical generators using hydrogen-oxygen cells were chosen to provide the main supplies on the Apollo spacecraft for landing on the surface of the moon in 1969. An added advantage of the cells was that they simultaneously provided water. NRDC was largely responsible for the forma-tion of Energy Conversion Ltd, a company that was set up to exploit Bacon's patents and to manufacture fuel cells, and which was supported by British Ropes Ltd, British Petroleum and Guest, Keen \& Nettlefold Ltd at Basingstoke. Bacon was their full-time consultant. In 1971 Energy Conversion's operation was moved to the UK Atomic Energy Research Establishment at Harwell, as Fuel Cells Ltd. Bacon remained with them until he retired in 1973.

  • 17 Cousteau, Jacques-Yves

    SUBJECT AREA: Ports and shipping
    [br]
    b. 11 June 1910 Saint-André-de-Cubzac, France
    [br]
    French marine explorer who invented the aqualung.
    [br]
    He was the son of a country lawyer who became legal advisor and travelling companion to certain rich Americans. At an early age Cousteau acquired a love of travel, of the sea and of cinematography: he made his first film at the age of 13. After an interrupted education he nevertheless passed the difficult entrance examination to the Ecole Navale in Brest, but his naval career was cut short in 1936 by injuries received in a serious motor accident. For his long recuperation he was drafted to Toulon. There he met Philippe Tailliez, a fellow naval officer, and Frédéric Dumas, a champion spearfisher, with whom he formed a long association and began to develop his underwater swimming and photography. He apparently took little part in the Second World War, but under cover he applied his photographic skills to espionage, for which he was awarded the Légion d'honneur after the war.
    Cousteau sought greater freedom of movement underwater and, with Emile Gagnan, who worked in the laboratory of Air Liquide, he began experimenting to improve portable underwater breathing apparatus. As a result, in 1943 they invented the aqualung. Its simple design and robust construction provided a reliable and low-cost unit and revolutionized scientific and recreational diving. Gagnan shunned publicity, but Cousteau revelled in the new freedom to explore and photograph underwater and exploited the publicity potential to the full.
    The Undersea Research Group was set up by the French Navy in 1944 and, based in Toulon, it provided Cousteau with the Opportunity to develop underwater exploration and filming techniques and equipment. Its first aims were minesweeping and exploration, but in 1948 Cousteau pioneered an extension to marine archaeology. In 1950 he raised the funds to acquire a surplus US-built minesweeper, which he fitted out to further his quest for exploration and adventure and named Calypso. Cousteau also sought and achieved public acclaim with the publication in 1953 of The Silent World, an account of his submarine observations, illustrated by his own brilliant photography. The book was an immediate success and was translated into twenty-two languages. In 1955 Calypso sailed through the Red Sea and the western Indian Ocean, and the outcome was a film bearing the same title as the book: it won an Oscar and the Palme d'Or at the Cannes film festival. This was his favoured medium for the expression of his ideas and observations, and a stream of films on the same theme kept his name before the public.
    Cousteau's fame earned him appointment by Prince Rainier as Director of the Oceanographie Institute in Monaco in 1957, a post he held until 1988. With its museum and research centre, it offered Cousteau a useful base for his worldwide activities.
    In the 1980s Cousteau turned again to technological development. Like others before him, he was concerned to reduce ships' fuel consumption by harnessing wind power. True to form, he raised grants from various sources to fund research and enlisted technical help, namely Lucien Malavard, Professor of Aerodynamics at the Sorbonne. Malavard designed a 44 ft (13.4 m) high non-rotating cylinder, which was fitted onto a catamaran hull, christened Moulin à vent. It was intended that its maiden Atlantic crossing in 1983 should herald a new age in ship propulsion, with large royalties to Cousteau. Unfortunately the vessel was damaged in a storm and limped to the USA under diesel power. A more robust vessel, the Alcyone, was fitted with two "Turbosails" in 1985 and proved successful, with a 40 per cent reduction in fuel consumption. However, oil prices fell, removing the incentive to fit the new device; the lucrative sales did not materialize and Alcyone remained the only vessel with Turbosails, sharing with Calypso Cousteau's voyages of adventure and exploration. In September 1995, Cousteau was among the critics of the decision by the French President Jacques Chirac to resume testing of nuclear explosive devices under the Mururoa atoll in the South Pacific.

  • 18 Perkins, Jacob

    [br]
    b. 9 July 1766 Newburyport, Massachusetts, USA
    d. 30 July 1849 London, England
    [br]
    American inventor of a nail-making machine and a method of printing banknotes, investigator of the use of steam at very high pressures.
    [br]
    Perkins's occupation was that of a gold-and silversmith; while he does not seem to have followed this after 1800, however, it gave him the skills in working metals which he would continue to employ in his inventions. He had been working in America for four years before he patented his nail-making machine in 1796. At the time there was a great shortage of nails because only hand-forged ones were available. By 1800, other people had followed his example and produced automatic nail-making machines, but in 1811 Perkins' improved machines were introduced to England by J.C. Dyer. Eventually Perkins had twenty-one American patents for a range of inventions in his name.
    In 1799 Perkins invented a system of engraving steel plates for printing banknotes, which became the foundation of modern siderographic work. It discouraged forging and was adopted by many banking houses, including the Federal Government when the Second United States Bank was inaugurated in 1816. This led Perkins to move to Philadelphia. In the intervening years, Perkins had improved his nail-making machine, invented a machine for graining morocco leather in 1809, a fire-engine in 1812, a letter-lock for bank vaults and improved methods of rolling out spoons in 1813, and improved armament and equipment for naval ships from 1812 to 1815.
    It was in Philadelphia that Perkins became interested in the steam engine, when he met Oliver Evans, who had pioneered the use of high-pressure steam. He became a member of the American Philosophical Society and conducted experiments on the compressibility of water before a committee of that society. Perkins claimed to have liquified air during his experiments in 1822 and, if so, was the real discoverer of the liquification of gases. In 1819 he came to England to demonstrate his forgery-proof system of printing banknotes, but the Bank of England was the only one which did not adopt his system.
    While in London, Perkins began to experiment with the highest steam pressures used up to that time and in 1822 took out his first of nineteen British patents. This was followed by another in 1823 for a 10 hp (7.5 kW) engine with only 2 in. (51 mm) bore, 12 in. (305 mm) stroke but a pressure of 500 psi (35 kg/cm2), for which he claimed exceptional economy. After 1826, Perkins abandoned his drum boiler for iron tubes and steam pressures of 1,500 psi (105 kg/cm2), but the materials would not withstand such pressures or temperatures for long. It was in that same year that he patented a form of uniflow cylinder that was later taken up by L.J. Todd. One of his engines ran for five days, continuously pumping water at St Katherine's docks, but Perkins could not raise more finance to continue his experiments.
    In 1823 one his high-pressure hot-water systems was installed to heat the Duke of Wellington's house at Stratfield Saye and it acquired a considerable vogue, being used by Sir John Soane, among others. In 1834 Perkins patented a compression ice-making apparatus, but it did not succeed commercially because ice was imported more cheaply from Norway as ballast for sailing ships. Perkins was often dubbed "the American inventor" because his inquisitive personality allied to his inventive ingenuity enabled him to solve so many mechanical challenges.

    d. 21 October 1973 British Virgin Islands
    [br]
    English pilot who pioneered worldwide air routes and developed an in-flight refuelling system which is in use today.
    [br]
    Alan Cobham was a man of many parts. He started as a veterinary assistant in France during the First World War, but transferred to the Royal Flying Corps in 1917. After the war he continued flying, by giving joy-rides and doing aerial photography work. In 1921 he joined the De Havilland Aircraft Company (see de Havilland, Geoffrey) as a test and charter pilot; he was also successful in a number of air races. During the 1920s Cobham made many notable flights to distant parts of the British Empire, pioneering possible routes for airline operations. During the early 1930s Sir Alan (he was knighted in 1926) devoted his attention to generating a public interest in aviation and to campaigning for more airfields. Cobham's Flying Circus toured the country giving flying displays and joy-rides, which for thousands of people was their first experience of flying.
    In 1933 Cobham planned a non-stop flight to India by refuelling his aircraft while flying: this was not a new idea but the process was still experimental. The flight was unsuccessful due to a fault in his aircraft, unrelated to the in-flight refuelling system. The following year Flight Refuelling Ltd was founded, and by 1939 two Short flying boats were operating the first inflight-refuelled service across the Atlantic. Inflight refuelling was not required during the early years of the Second World War, so Cobham turned to other projects such as thermal de-icing of wings, and a scheme which was not carried out, for delivering fighters to the Middle East by towing them behind Wellington bombers.
    After the Second World War the fortunes of Flight Refuelling Ltd were at a low ebb, especially when British South American Airways abandoned the idea of using in-flight refuelling. Then an American contract and the use of their tanker aircraft to ferry oil during the Berlin Airlift saved the day. In 1949 Cobham's chief designer, Peter Macgregor, came up with an idea for refuelling fighters using a probe and drogue system. A large tanker aircraft trailed a hose with a conical drogue at the free end. The fighter pilot manoeuvred the probe, fitted to his aircraft, so that it locked into the drogue, enabling fuel to be transferred. Since the 1950s this system has become the effective world standard.

    [br]
    b. 1812 England
    d. 1887 England
    [br]
    English instrument maker and photographer, pioneer of microphotography.
    [br]
    The son of a scientific instrument maker, Dancer was educated privately in Liverpool, where from 1817 his father practised his trade. John Benjamin became a skilled instrument maker in his own right, assisting in the family business until his father's death in 1835. He set up on his own in Liverpool in 1840 and in Manchester in 1841. In the course of his career Dancer made instruments for several of the leading scientists of the day, his clients including Brewster, Dalton and Joule.
    Dancer became interested in photography as soon as the new art was announced in 1839 and practised the processes of both Talbot and Daguerre. It was later claimed that as early as 1839 he used an achromatic lens combination to produce a minute image on a daguerreotype plate, arguably the world's first microphotograph and the precursor of modern microfilm. It was not until the introduction of Archer's wet-collodion process in 1851 that Dancer was able to perfect the technique however. He went on to market a long series of microphotographs which proved extremely popular with both the public and contemporary photographers. It was examples of Dancer's microphotographs that prompted the French photographer Dagron to begin his work in the same field. In 1853 Dancer constructed a binocular stereoscopic camera, the first practicable instrument of its type. In an improved form it was patented and marketed in 1856.
    Dancer also made important contributions to the magic lantern. He was the first to suggest the use of limelight as an illuminant, pioneered the use of photographic lantern slides and devised an ingenious means of switching gas from one lantern illuminant to another to produce what were known as dissolving views. He was a resourceful innovator in other fields of instrumentation and suggested several other minor improvements to scientific apparatus before his working life was sadly terminated by the loss of his sight.
