18 Archer, Frederick Scott
SUBJECT AREA: Photography, film and optics[br]b. 1813 Bishops Stortford, Hertfordshire, Englandd. 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.[br]Bibliography1851, Chemist (March) (announced Archer's process).Further ReadingJ.Werge, 1890, The Evolution of Photography.H.Gernsheim and A.Gernsheim, 1969, The History of "Photography", rev. edn, London.JWBiographical history of technology > Archer, Frederick Scott

19 Hunt, Robert
SUBJECT AREA: Photography, film and optics[br]b. 6 September 1807 Devonport, Devon, Englandd. 19 March 1887 England[br]English photographic pioneer and writer.[br]A chemist by training, Hunt took an early interest in photography and during the 1840s devised several original photographic processes and techniques. The properties of iron sulphate as a developing agent, widely used by wet-collodion photographers, were first described by Hunt in 1844. He was a prolific author and it was as a writer that he was most influential. In 1841 he published the first substantial English-language photographic manual, a work that was to run to six editions. Perhaps his most important work was his Researches on Light, first published in 1844, with a second edition containing considerable additional material appearing in 1854. In 1851 Hunt was appointed Professor of Mechanical Science at the Royal School of Mines in London. He was a founder member of the London (later Royal) Photographic Society in 1853.[br]Principal Honours and DistinctionsMember of the Royal Society 1854.Further ReadingC.Thomas, 1988, Views and Likenesses, Truro: Royal Institution of Cornwall (a brief account of Hunt's life and work).H.Gernsheim and A.Gernsheim, 1969, The History of Photography, rev. edn, London.JW -
20 Niepce, Joseph Nicéphore
SUBJECT AREA: Photography, film and optics[br]b. 1765 Franced. 5 July 1833 Chalon, France[br]French inventor who was the first to produce permanent photographic images with the aid of a camera.[br]Coming from a prosperous family, Niepce was educated in a Catholic seminary and destined for the priesthood. The French Revolution intervened and Niepce became an officer in an infantry regiment. An attack of typhoid fever in Italy ended his military career, and he returned to France and was married. Returning to his paternal home in Chalon in 1801, he joined with his brother Claude to construct an ingenious engine called the pyréolophore, which they patented in 1807. The French Government also encouraged the brothers in their attempts to produce large quantities of indigo-blue dye from wood, a venture that was ultimately unsuccessful.Nicéphore began to experiment with lithography, which led him to take an interest in the properties of light-sensitive materials. He pursued this interest after Claude moved to Paris in 1816 and is reported to have made negative images in a camera obscura using paper soaked in silver chloride. Niepce went on to experiment with bitumen of judea, a substance that hardened on exposure to light. In 1822, using bitumen of judea on glass, he produced a heliograph from an engraving. The first images from nature may have been made as early as 1824, but the world's earliest surviving photographic image was made in 1826. A view of the courtyard of Niepce's home in Chalon was captured on a pewter plate coated with bitumen of judea; an exposure of several hours was required, the softer parts of the bitumen being dissolved away by a solvent to reveal the image.In 1827 he took examples of his work to London where he met Francis Bauer, Secretary of the Royal Society. Nothing came of this meeting, but on returning to France Niepce continued his work and in 1829 entered into a formal partnership with L.J.M. Daguerre with a view to developing their mutual interest in capturing images formed by the camera obscura. However, the partnership made only limited progress and was terminated by Niepce's death in 1833. It was another six years before the announcement of the first practicable photographic processes was made.[br]Bibliography1973.
