    b. 18 November 1859 Durham, England
    d. 13 June 1935 Durham, England
    [br]
    English mine manager, expert in preventing mine explosions and inventor of a coal-face conveyor.
    [br]
    After leaving Durham college of Physical Science and having been apprenticed in different mines, he received the certificate for colliery managers and subsequently, in 1887, was appointed Manager of all the mines of Charlaw and Sacriston collieries in Durham. He remained in this position for the rest of his working life.
    Frequent explosions in mines led him to investigate the causes. He was among the first to recognize the role contributed by coal-dust on mine roads, pioneered the use of inert rock-or stone-dust to render the coal-dust harmless and was the originator of many technical terms on the subject. He contributed many papers on explosion and was appointed a member of many advisory committees on prevention measures. A liquid-air rescue apparatus, designed by him and patented in 1910, was installed in various parts of the country.
    Blackett also developed various new devices in mining machinery. He patented a wire-rope socket which made use of a metal wedge; invented a rotary tippler driven by frictional contact instead of gearing and which stopped automatically; and he designed a revolving cylindrical coal-washer, which also gained interest among German mining engineers. His most important invention, the first successful coal-face conveyor, was patented in 1902. It was driven by compressed air and consisted of a trough running along the length of the race through which ran an endless scraper chain. Thus fillers cast the coal into the trough, and the scraper chain drew it to the main gate to be loaded into trams.

    [br]
    [br]
    Carlson studied physics at the California Institute of Technology and in 1930 he took a research position at Bell Telephone Laboratories, but soon transferred to their patent department. To equip himself in this field, Carlson studied law, and in 1934 he became a patent attorney at P.R.Mallory \& Co., makers of electrical apparatus. He was struck by the difficulty in obtaining copies of documents and drawings; indeed, while still at school, he had encountered printing problems in trying to produce a newsletter for amateur chemists. He began experimenting with various light-sensitive substances, and by 1937 he had conceived the basic principles of xerography ("dry writing"), using the property of certain substances of losing an electrostatic charge when light impinges on them. His work for Mallory brought him into contact with the Battelle Memorial Institute, the world's largest non-profit research organization; their subsidiary, set up to develop promising ideas, took up Carlson's invention. Carlson received his first US patent for the process in 1940, with two more in 1942, and he assigned to Battelle exclusive patent rights in return for a share of any future proceeds. It was at Battelle that selenium was substituted as the light-sensitive material.
    In 1946 the Haloid Company of Rochester, manufacturers of photographic materials and photocopying equipment, heard of the Xerox copier and, seeing it as a possible addition to their products, took out a licence to develop it commercially. The first Xerox Copier was tested during 1949 and put on the market the following year. The process soon began to displace older methods, such as Photostat, but its full impact on the public came in 1959 with the advent of the Xerox 914 Copier. It is fair to apply the overworked word "revolution" to the change in copying methods initiated by Carlson. He became a multimillionaire from his royalties and stock holding, and in his last years he was able to indulge in philanthropic activities.

  • 31 Demenÿ, Georges

    [br]
    b. 1850 Douai, France d. 1917
    [br]
    French chronophotographer.
    [br]
    As a young man Georges Demenÿ was a pioneer of physical education in France, and this led him to contact the physiologist Professor Marey in 1880. Marey had made a special study of animal movement, and Demenÿ hoped to work with him on research into physiological problems related to gymnastics. He joined Marey the following year, and when in 1882 the Physiological Station was set up near Paris to develop sequence photography for the study of movement. Demenÿ was made Head of the laboratory. He worked with the multiple-image fixed-plate cameras, and was chiefly responsible for the analysis of the records, having considerable mathematical and graphical ability. He also appeared as the subject in a number of the sequences. When in 1888 Marey began the development of a film camera, Demenÿ was involved in its design and operation. He became interested in the possibility of using animated sequence photographs as an aid to teaching of the deaf. He made close-up records of himself speaking short phrases, "Je vous aime" and "Vive la France" for example, which were published in such journals as Paris Photographe and La Nature in 1891 and 1892. To present these in motion, he devised the Phonoscope, which he patented on 3 March 1892. The series of photographs were mounted around the circumference of a disc and viewed through a counter-rotating slotted disc. The moving images could be viewed directly, or projected onto a screen. La Nature reported tests he had made in which deaf lip readers could interpret accurately what was being said. On 20 December 1892 Demenÿ formed a company, Société Générale du Phonoscope, to exploit his invention, hoping that "speaking portraits" might replace family-album pictures. This commercial activity led to a rift between Marey and Demenÿ in July 1893. Deprived of access to the film cameras, Demenÿ developed designs of his own, patenting new camera models in France on 10 October 1893 and 27 July 1894. The design covered by the latter had been included in English and German patents filed in December 1893, and was to be of some significance in the early development of cinematography. It was for an intermittent movement of the film, which used an eccentrically mounted blade or roller that, as it rotated, bore on the film, pulling down the length of one frame. As the blade moved away, the film loop so formed was taken up by the rotation of the take-up reel. This "beater" movement was employed extensively in the early years of cinematography, being effective yet inexpensive. It was first employed in the Chronophotographe apparatus marketed by Gaumont, to whom Demenÿ had licensed the patent rights, from the autumn of 1896. Demenÿ's work provided a link between the scientific purposes of sequence photography— chronophotography—and the introduction of commercial cinematography.

    [br]
    b. August 1860 Brittany, France
    d. 28 September 1935 Twickenham, England
    [br]
    Scottish inventor and photographer.
    [br]
    Dickson was born in France of English and Scottish parents. As a young man of almost 19 years, he wrote in 1879 to Thomas Edison in America, asking for a job. Edison replied that he was not taking on new staff at that time, but Dickson, with his mother and sisters, decided to emigrate anyway. In 1883 he contacted Edison again, and was given a job at the Goerk Street laboratory of the Edison Electric Works in New York. He soon assumed a position of responsibility as Superintendent, working on the development of electric light and power systems, and also carried out most of the photography Edison required. In 1888 he moved to the Edison West Orange laboratory, becoming Head of the ore-milling department. When Edison, inspired by Muybridge's sequence photographs of humans and animals in motion, decided to develop a motion picture apparatus, he gave the task to Dickson, whose considerable skills in mechanics, photography and electrical work made him the obvious choice. The first experiments, in 1888, were on a cylinder machine like the phonograph, in which the sequence pictures were to be taken in a spiral. This soon proved to be impractical, and work was delayed for a time while Dickson developed a new ore-milling machine. Little progress with the movie project was made until George Eastman's introduction in July 1889 of celluloid roll film, which was thin, tough, transparent and very flexible. Dickson returned to his experiments in the spring of 1891 and soon had working models of a film camera and viewer, the latter being demonstrated at the West Orange laboratory on 20 May 1891. By the early summer of 1892 the project had advanced sufficiently for commercial exploitation to begin. The Kinetograph camera used perforated 35 mm film (essentially the same as that still in use in the late twentieth century), and the kinetoscope, a peep-show viewer, took fifty feet of film running in an endless loop. Full-scale manufacture of the viewers started in 1893, and they were demonstrated on a number of occasions during that year. On 14 April 1894 the first kinetoscope parlour, with ten viewers, was opened to the public in New York. By the end of that year, the kinetoscope was seen by the public all over America and in Europe. Dickson had created the first commercially successful cinematograph system. Dickson left Edison's employment on 2 April 1895, and for a time worked with Woodville Latham on the development of his Panoptikon projector, a projection version of the kinetoscope. In December 1895 he joined with Herman Casier, Henry N.Marvin and Elias Koopman to form the American Mutoscope Company. Casier had designed the Mutoscope, an animated-picture viewer in which the sequences of pictures were printed on cards fixed radially to a drum and were flipped past the eye as the drum rotated. Dickson designed the Biograph wide-film camera to produce the picture sequences, and also a projector to show the films directly onto a screen. The large-format images gave pictures of high quality for the period; the Biograph went on public show in America in September 1896, and subsequently throughout the world, operating until around 1905. In May 1897 Dickson returned to England and set up as a producer of Biograph films, recording, among other subjects, Queen Victoria's Diamond Jubilee celebrations in 1897, Pope Leo XIII in 1898, and scenes of the Boer War in 1899 and 1900. Many of the Biograph subjects were printed as reels for the Mutoscope to produce the "what the butler saw" machines which were a feature of fairgrounds and seaside arcades until modern times. Dickson's contact with the Biograph Company, and with it his involvement in cinematography, ceased in 1911.

    [br]
    b. 9 April 1830 Kingston upon Thames, England
    d. 8 May 1904 Kingston upon Thames, England
    [br]
    English photographer and pioneer of sequence photography of movement.
    [br]
    He was born Edward Muggeridge, but later changed his name, taking the Saxon spelling of his first name and altering his surname, first to Muygridge and then to Muybridge. He emigrated to America in 1851, working in New York in bookbinding and selling as a commission agent for the London Printing and Publishing Company. Through contact with a New York daguerreotypist, Silas T.Selleck, he acquired an interest in photography that developed after his move to California in 1855. On a visit to England in 1860 he learned the wet-collodion process from a friend, Arthur Brown, and acquired the best photographic equipment available in London before returning to America. In 1867, under his trade pseudonym "Helios", he set out to record the scenery of the Far West with his mobile dark-room, christened "The Flying Studio".
    His reputation as a photographer of the first rank spread, and he was commissioned to record the survey visit of Major-General Henry W.Halleck to Alaska and also to record the territory through which the Central Pacific Railroad was being constructed. Perhaps because of this latter project, he was approached by the President of the Central Pacific, Leland Stanford, to attempt to photograph a horse trotting at speed. There was a long-standing controversy among racing men as to whether a trotting horse had all four hooves off the ground at any point; Stanford felt that it did, and hoped than an "instantaneous" photograph would settle the matter once and for all. In May 1872 Muybridge photographed the horse "Occident", but without any great success because the current wet-collodion process normally required many seconds, even in a good light, for a good result. In April 1873 he managed to produce some better negatives, in which a recognizable silhouette of the horse showed all four feet above the ground at the same time.
    Soon after, Muybridge left his young wife, Flora, in San Francisco to go with the army sent to put down the revolt of the Modoc Indians. While he was busy photographing the scenery and the combatants, his wife had an affair with a Major Harry Larkyns. On his return, finding his wife pregnant, he had several confrontations with Larkyns, which culminated in his shooting him dead. At his trial for murder, in February 1875, Muybridge was acquitted by the jury on the grounds of justifiable homicide; he left soon after on a long trip to South America.
    He again took up his photographic work when he returned to North America and Stanford asked him to take up the action-photography project once more. Using a new shutter design he had developed while on his trip south, and which would operate in as little as 1/1,000 of a second, he obtained more detailed pictures of "Occident" in July 1877. He then devised a new scheme, which Stanford sponsored at his farm at Palo Alto. A 50 ft (15 m) long shed was constructed, containing twelve cameras side by side, and a white background marked off with vertical, numbered lines was set up. Each camera was fitted with Muybridge's highspeed shutter, which was released by an electromagnetic catch. Thin threads stretched across the track were broken by the horse as it moved along, closing spring electrical contacts which released each shutter in turn. Thus, in about half a second, twelve photographs were obtained that showed all the phases of the movement.
    Although the pictures were still little more than silhouettes, they were very sharp, and sequences published in scientific and photographic journals throughout the world excited considerable attention. By replacing the threads with an electrical commutator device, which allowed the release of the shutters at precise intervals, Muybridge was able to take series of actions by other animals and humans. From 1880 he lectured in America and Europe, projecting his results in motion on the screen with his Zoopraxiscope projector. In August 1883 he received a grant of $40,000 from the University of Pennsylvania to carry on his work there. Using the vastly improved gelatine dry-plate process and new, improved multiple-camera apparatus, during 1884 and 1885 he produced over 100,000 photographs, of which 20,000 were reproduced in Animal Locomotion in 1887. The subjects were animals of all kinds, and human figures, mostly nude, in a wide range of activities. The quality of the photographs was extremely good, and the publication attracted considerable attention and praise.
    Muybridge returned to England in 1894; his last publications were Animals in Motion (1899) and The Human Figure in Motion (1901). His influence on the world of art was enormous, over-turning the conventional representations of action hitherto used by artists. His work in pioneering the use of sequence photography led to the science of chronophotography developed by Marey and others, and stimulated many inventors, notably Thomas Edison to work which led to the introduction of cinematography in the 1890s.

  • 34 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.

  • 35 Volta, Alessandro Giuseppe Antonio Anastasio

    SUBJECT AREA: Electricity
    [br]
    b. 18 February 1745 Como, Italy
    d. 5 March 1827 Como, Italy
    [br]
    Italian physicist, discoverer of a source of continuous electric current from a pile of dissimilar metals.
    [br]
    Volta had an early command of English, French and Latin, and also learned to read Dutch and Spanish. After completing studies at the Royal Seminary in Como he was involved in the study of physics, chemistry and electricity. He became a teacher of physics in his native town and in 1779 was appointed Professor of Physics at the University of Pavia, a post he held for forty years.
    With a growing international reputation and a wish to keep abreast of the latest developments, in 1777 he began the first of many travels abroad. A journey started in 1781 to Switzerland, Germany, Belgium, Holland, France and England lasted about one year. By 1791 he had been elected to membership of many learned societies, including those in Zurich, Berlin, Berne and Paris. Volta's invention of his pile resulted from a controversy with Luigi Galvani, Professor of Anatomy at the University of Bologna. Galvani discovered that the muscles of frogs' legs contracted when touched with two pieces of different metals and attributed this to a phenomenon of the animal tissue. Volta showed that the excitation was due to a chemical reaction resulting from the contact of the dissimilar metals when moistened. His pile comprised a column of zinc and silver discs, each pair separated by paper moistened with brine, and provided a source of continuous current from a simple and accessible source. The effectiveness of the pile decreased as the paper dried and Volta devised his crown of cups, which had a longer life. In this, pairs of dissimilar metals were placed in each of a number of cups partly filled with an electrolyte such as brine. Volta first announced the results of his experiments with dissimilar metals in 1800 in a letter to Sir Joseph Banks, President of the Royal Society. This letter, published in the Transactions of the Royal Society, has been regarded as one of the most important documents in the history of science. Large batteries were constructed in a number of laboratories soon after Volta's discoveries became known, leading immediately to a series of developments in electrochemistry and eventually in electromagnetism. Volta himself made little further contribution to science. In recognition of his achievement, at a meeting of the International Electrical Congress in Paris in 1881 it was agreed to name the unit of electrical pressure the "volt".
