  • 1 Archer, Frederick Scott

    [br]
    b. 1813 Bishops Stortford, Hertfordshire, England
    d. May 1857 London, England
    [br]
    English photographer, inventor of the wet-collodion process, the dominant photographic process between 1851 and c.1880.
    [br]
    Apprenticed to a silversmith in London, Archer's interest in coin design and sculpture led to his taking up photography in 1847. Archer began experiments to improve Talbot's calotype process and by 1848 he was investigating the properties of a newly discovered material, collodion, a solution of gun-cotton in ether. In 1851 Archer published details of a process using collodion on glass plates as a carrier for silver salts. The process combined the virtues of both the calotype and the daguerreotype processes, then widely practised, and soon displaced them from favour. Collodion plates were only sensitive when moist and it was therefore essential to use them immediately after they had been prepared. Popularly known as "wet plate" photography, it became the dominant photographic process for thirty years.
    Archer introduced other minor photographic innovations and in 1855 patented a collodion stripping film. He had not patented the wet-plate process, however, and made no financial gain from his photographic work. He died in poverty in 1857, a matter of some embarrassment to his contemporaries. A subscription fund was raised, to which the Government was subsequently persuaded to add an annual pension.

  • 2 Muybridge, Eadweard

    [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.

  • 3 Niepce de St Victor, Claude Félix Abel

    [br]
    b. 1805 Saint-Cyr, France
    d. 1870 France
    [br]
    French soldier and photographic scientist, inventor of the first practicable glass negative process.
    [br]
    A cousin of the photographic pioneer J.N. Niepce, he attended the military school of Saumur, graduating in 1827. Niepce de St Victor had wide scientific interests, but came to photography indirectly from experiments he made on fading dyes in military uniforms. He was transferred to the Paris Municipal Guard in 1845 and was able to set up a chemical laboratory to conduct research. From photographic experiments performed in his spare time, Niepce de St Victor devised the first practicable photographic process on glass in 1847. Using albumen derived from the white of eggs as a carrier for silver iodide, he prepared finely detailed negatives which produced positive prints far sharper than those made with the paper negatives of Talbot's calotype process. Exposure times were rather long, however, and the albumen-negative process was soon displaced by the wet-collodion process introduced in 1851, although albumen positives on glass continued to be used for high-quality stereoscopic views and lantern slides. In 1851 Niepce de St Victor described a photographic colour process, and between 1853 and 1855 he developed his famous cousin's bitumen process into a practicable means of producing photographically derived printing plates. He then went on to investigate the use of uranium salts in photography. He presented twenty-six papers to the Académie des Sciences between 1847 and 1862.

    [br]
    b. 1819 England
    d. 1875 Jersey, Channel Islands
    [br]
    English photographer and writer on photography.
    [br]
    In 1841, while studying at Cambridge, Sutton became interested in photography and tried out the current processes, daguerreotype, calotype and cyanotype among them. He subsequently settled in Jersey, where he continued his photographic studies. In 1855 he opened a photographic printing works in Jersey, in partnership with L.-D. Blanquart- Evrard, exploiting the latter's process for producing developed positive prints. He started and edited one of the first photographic periodicals, Photographic Notes, in 1856; until its cessation in 1867, his journal presented a fresher view of the world of photography than that given by its London-based rivals. He also drew up the first dictionary of photography in 1858.
    In 1859 Sutton designed and patented a wideangle lens in which the space between two meniscus lenses, forming parts of a sphere and sealed in a metal rim, was filled with water; the lens so formed could cover an angle of up to 120 degrees at an aperture of f12. Sutton's design was inspired by observing the images produced by the water-filled sphere of a "snowstorm" souvenir brought home from Paris! Sutton commissioned the London camera-maker Frederick Cox to make the Panoramic camera, demonstrating the first model in January 1860; it took panoramic pictures on curved glass plates 152×381 mm in size. Cox later advertised other models in a total of four sizes. In January 1861 Sutton handed over manufacture to Andrew Ross's son Thomas Ross, who produced much-improved lenses and also cameras in three sizes. Sutton then developed the first single-lens reflex camera design, patenting it on 20 August 1961: a pivoted mirror, placed at 45 degrees inside the camera, reflected the image from the lens onto a ground glass-screen set in the top of the camera for framing and focusing. When ready, the mirror was swung up out of the way to allow light to reach the plate at the back of the camera. The design was manufactured for a few years by Thomas Ross and J.H. Dallmeyer.
    In 1861 James Clerk Maxwell asked Sutton to prepare a series of photographs for use in his lecture "On the theory of three primary colours", to be presented at the Royal Institution in London on 17 May 1861. Maxwell required three photographs to be taken through red, green and blue filters, which were to be printed as lantern slides and projected in superimposition through three projectors. If his theory was correct, a colour reproduction of the original subject would be produced. Sutton used liquid filters: ammoniacal copper sulphate for blue, copper chloride for the green and iron sulphocyanide for the red. A fourth exposure was made through lemon-yellow glass, but was not used in the final demonstration. A tartan ribbon in a bow was used as the subject; the wet-collodion process in current use required six seconds for the blue exposure, about twice what would have been needed without the filter. After twelve minutes no trace of image was produced through the green filter, which had to be diluted to a pale green: a twelve-minute exposure then produced a serviceable negative. Eight minutes was enough to record an image through the red filter, although since the process was sensitive only to blue light, nothing at all should have been recorded. In 1961, R.M.Evans of the Kodak Research Laboratory showed that the red liquid transmitted ultraviolet radiation, and by an extraordinary coincidence many natural red dye-stuffs reflect ultraviolet. Thus the red separation was made on the basis of non-visible radiation rather than red, but the net result was correct and the projected images did give an identifiable reproduction of the original. Sutton's photographs enabled Maxwell to establish the validity of his theory and to provide the basis upon which all subsequent methods of colour photography have been founded.

  • 7 Dancer, John Benjamin

    [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.

    [br]
    b. 1834 Manchester, England
    d. 1885 Margate, Kent, England
    [br]
    English photographer, inventor of the Woodburytype process.
    [br]
    Having been apprenticed to be an engineer, Woodbury left England in 1851 to seek his fortune in the Australian gold-fields. Like many others, he failed, and after a series of transient jobs found a post as Draughtsman at the Melbourne Waterworks. He then went on to Java, where he practised wet-collodion photography before returning to England finally in 1863. Woodbury settled in Birmingham, where like most contemporary photographers he was concerned to find a solution to the troublesome problem of fading prints. He began working the carbon process, and in 1866 and 1867 took out a series of patents which were to lead to the development of the process that took his name. Woodburytypes were continuous-tone prints of high quality that could be mass produced more cheaply than the traditional silver print. This was an important innovation and Woodburytypes were extensively used for quality book illustrations until the introduction of more versatile photomechanical processes in the 1890s. In all, Woodbury took out twenty patents between 1864 and 1884, some relating to a wide range of photographic devices. He was still working to simplify the Woodburytype process when he died from an overdose of laudanum.

    Woodbury took out a series of patents on his process, the most significant being: 23 September 1864, British patent no. 2,338; 12 January 1866, British patent no. 105; 11 February 1866, British patent no. 505; 8 May 1866, British patent no. 1,315; 24 July 1866, British patent no. 1,918.
