3 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.

6 Talbot, William Henry Fox
SUBJECT AREA: Photography, film and optics[br]b. 11 February 1800 Melbury, Englandd. 17 September 1877 Lacock, Wiltshire, England[br]English scientist, inventor of negative—positive photography and practicable photo engraving.[br]Educated at Harrow, where he first showed an interest in science, and at Cambridge, Talbot was an outstanding scholar and a formidable mathematician. He published over fifty scientific papers and took out twelve English patents. His interests outside the field of science were also wide and included Assyriology, etymology and the classics. He was briefly a Member of Parliament, but did not pursue a parliamentary career.Talbot's invention of photography arose out of his frustrating attempts to produce acceptable pencil sketches using popular artist's aids, the camera discura and camera lucida. From his experiments with the former he conceived the idea of placing on the screen a paper coated with silver salts so that the image would be captured chemically. During the spring of 1834 he made outline images of subjects such as leaves and flowers by placing them on sheets of sensitized paper and exposing them to sunlight. No camera was involved and the first images produced using an optical system were made with a solar microscope. It was only when he had devised a more sensitive paper that Talbot was able to make camera pictures; the earliest surviving camera negative dates from August 1835. From the beginning, Talbot noticed that the lights and shades of his images were reversed. During 1834 or 1835 he discovered that by placing this reversed image on another sheet of sensitized paper and again exposing it to sunlight, a picture was produced with lights and shades in the correct disposition. Talbot had discovered the basis of modern photography, the photographic negative, from which could be produced an unlimited number of positives. He did little further work until the announcement of Daguerre's process in 1839 prompted him to publish an account of his negative-positive process. Aware that his photogenic drawing process had many imperfections, Talbot plunged into further experiments and in September 1840, using a mixture incorporating a solution of gallic acid, discovered an invisible latent image that could be made visible by development. This improved calotype process dramatically shortened exposure times and allowed Talbot to take portraits. In 1841 he patented the process, an exercise that was later to cause controversy, and between 1844 and 1846 produced The Pencil of Nature, the world's first commercial photographically illustrated book.Concerned that some of his photographs were prone to fading, Talbot later began experiments to combine photography with printing and engraving. Using bichromated gelatine, he devised the first practicable method of photo engraving, which was patented as Photoglyphic engraving in October 1852. He later went on to use screens of gauze, muslin and finely powdered gum to break up the image into lines and dots, thus anticipating modern photomechanical processes.Talbot was described by contemporaries as the "Father of Photography" primarily in recognition of his discovery of the negative-positive process, but he also produced the first photomicrographs, took the first high-speed photographs with the aid of a spark from a Leyden jar, and is credited with proposing infra-red photography. He was a shy man and his misguided attempts to enforce his calotype patent made him many enemies. It was perhaps for this reason that he never received the formal recognition from the British nation that his family felt he deserved.[br]Principal Honours and DistinctionsFRS March 1831.

8 Lippman, Gabriel
SUBJECT AREA: Photography, film and optics[br]b. 16 August 1845 Hallerick, Luxembourgd. 14 July 1921 at sea, in the North Atlantic[br]French physicist who developed interference colour photography.[br]Born of French parents, Lippman's work began with a distinguished career in classics, philosophy, mathematics and physics at the Ecole Normale in Luxembourg. After further studies in physics at Heidelberg University, he returned to France and the Sorbonne, where he was in 1886 appointed Director of Physics. He was a leading pioneer in France of research into electricity, optics, heat and other branches of physics.In 1886 he conceived the idea of recording the existence of standing waves in light when it is reflected back on itself, by photographing the colours so produced. This required the production of a photographic emulsion that was effectively grainless: the individual silver halide crystals had to be smaller than the shortest wavelength of light to be recorded. Lippman succeeded in this and in 1891 demonstrated his process. A glass plate was coated with a grainless emulsion and held in a special plate-holder, glass towards the lens. The back of the holder was filled with mercury, which provided a perfect reflector when in contact with the emulsion. The standing waves produced during the exposure formed laminae in the emulsion, with the number of laminae being determined by the wavelength of the incoming light at each point on the image. When the processed plate was viewed under the correct lighting conditions, a theoretically exact reproduction of the colours of the original subject could be seen. However, the Lippman process remained a beautiful scientific demonstration only, since the ultra-fine-grain emulsion was very slow, requiring exposure times of over 10,000 times that of conventional negative material. Any method of increasing the speed of the emulsion also increased the grain size and destroyed the conditions required for the process to work.[br]Principal Honours and DistinctionsRoyal Photographic Society Progress Medal 1897.

9 Blanquart-Evrard, Louis-Désiré
SUBJECT AREA: Photography, film and optics[br]b. 2 August 1802 Lille, Franced. 28 April 1872 Lille, France[br]French photographer, photographic innovator and entrepreneur.[br]After beginning his working life in a tobacco company, Blanquart-Evrard became Laboratory Assistant to a chemist. He also became interested in painting on ivory and porcelain, foreshadowing a life-long interest in science and art. Following his marriage to the daughter of a textile merchant, Blanquart-Evrard became a partner in the family business in Lyon. During the 1840s he became interested in Talbot's calotype process and found that by applying gallic acid alone, as a developing agent after exposure, the exposure time could be shorter and the resulting image clearer. Blanquart-Evrard recognized that his process was well suited to producing positive prints in large numbers. During 1851 and 1852, in association with an artist friend, he became involved in producing quantities of prints for book illustrations. In 1849 he had announced a glass negative process similar to that devised two years earlier by Niepcc de St Victor. The carrying agent for silver salts was albumen, and more far-reaching was his albumen-coated printing-out paper announced in 1850. Albumen printing paper was widely adopted and the vast majority of photographs made in the nineteenth century were printed in this form. In 1870 Blanquart-Evrard began an association with the pioneer colour photographer Ducos du Hauron with a view to opening a three-colour printing establishment. Unfortunately plans were delayed by the Franco-Prussian War, and Blanquart-Evrard died in 1872 before the project could be brought to fruition.[br]Bibliography1851, Traité de photographie sur papier, Paris (provides details of his improvements to Talbot's process).Further ReadingJ.M.Eder, 1945, History of Photography, trans.
