4 Joly, John
SUBJECT AREA: Photography, film and optics[br]b. 1857 Holywood, King's County (now County Down, Northwern Ireland), Irelandd. 8 December 1933 Dublin, Eire[br]Irish pioneer of additive screen-plate colour photography.[br]Professor of Physics at Trinity College, Dublin, Joly developed a concept first suggested by Ducos du Hauron, creating in 1893 a process in which fine transparent red, green and blue lines, less than 0.1 mm wide, were ruled on a glass plate. The coloured inks were aniline dyes mixed with gum. This screen plate was held in close contact with a photographic negative plate which was exposed through the screen in a camera. The processed negative was printed onto a positive plate, and a viewing screen, similar to that used for taking, was bound up with it in careful register, to reproduce the original colours. The process was patented in 1894, and marketed in 1895. It was the first commercially successful additive screen-plate process to appear. While the results could be quite acceptable, the inadequate colour sensitivity of the negative plates then available limited the usefulness of this process. Professor Joly's other achievements included geological research and the treatment of cancer by radium.[br]Further ReadingJ.S.Friedman, 1944, History of Colour Photography, Boston.B.Coe, 1978, Colour Photography: The First Hundred Years, London.

5 Ducos du Hauron, Arthur-Louis
SUBJECT AREA: Photography, film and optics[br]b. 1837 Langon, Bordeaux, Franced. 19 August 1920 Agen, France[br]French scientist and pioneer of colour photography.[br]The son of a tax collector, Ducos du Hauron began researches into colour photography soon after the publication of Clerk Maxwell's experiment in 1861. In a communication sent in 1862 for presentation at the Académie des Sciences, but which was never read, he outlined a number of methods for photography of colours. Subsequently, in his book Les Couleurs en photographie, published in 1869, he outlined most of the principles of additive and subtractive colour photography that were later actually used. He covered additive processes, developed from Clerk Maxwell's demonstrations, and subtractive processes which could yield prints. At the time, the photographic materials available prevented the processes from being employed effectively. The design of his Chromoscope, in which transparent reflectors could be used to superimpose three additive images, was sound, however, and formed the basis of a number of later devices. He also proposed an additive system based on the use of a screen of fine red, yellow and blue lines, through which the photograph was taken and viewed. The lines blended additively when seen from a certain distance. Many years later, in 1907, Ducos du Hauron was to use this principle in an early commercial screen-plate process, Omnicolore. With his brother Alcide, he published a further work in 1878, Photographie des Couleurs, which described some more-practical subtractive processes. A few prints made at this time still survive and they are remarkably good for the period. In a French patent of 1895 he described yet another method for colour photography. His "polyfolium chromodialytique" involved a multiple-layer package of separate red-, green-and blue-sensitive materials and filters, which with a single exposure would analyse the scene in terms of the three primary colours. The individual layers would be separated for subsequent processing and printing. In a refined form, this is the principle behind modern colour films. In 1891 he patented and demonstrated the anaglyph method of stereoscopy, using superimposed red and green left and right eye images viewed through green and red filters. Ducos du Hauron's remarkable achievement was to propose theories of virtually all the basic methods of colour photography at a time when photographic materials were not adequate for the purpose of proving them correct. For his work on colour photography he was awarded the Progress Medal of the Royal Photographic Society in 1900, but despite his major contributions to colour photography he remained in poverty for much of his later life.[br]Further ReadingB.Coe, 1978, Colour Photography: The First Hundred Years, London.

6 Wratten, Frederick Charles Luther
SUBJECT AREA: Photography, film and optics[br]b. 1840 Englandd. 8 April 1926 London, England[br]English inventor and manufacturer, founder of one of the first successful gelatine dry-plate companies.[br]He started his working life as a schoolteacher, but in his early twenties he moved to London to become a clerk with a photographic wholesaler, Soloman. There Wratten became interested in photography, and on the announcement of the new gelatine dry-plate processes he began to conduct his own experiments. In 1876 he devised a means of drying gelatine emulsions and removing excess silver with alcohol, and published details in 1877 and 1878. It was during this period that he formed a partnership with Henry Wainwright to manufacture and sell photographic materials. The mass production of gelatine dry plates was a British invention and monopoly, and the new firm of Wratten \& Wainwright was one of the first in the field and soon proved to be amongst the most successful. The business exported extensively to Europe, introducing a succession of plates of increasing sensitivity. Wratten continued to trade under the same name when his partner Wainwright died in 1882. His success continued, and in 1890 he moved the company to a newly equipped factory in Croydon, near London. Six years later Wratten incorporated as co-owners of the business his son, S.H.Wainwright and a young graduate from London University, C.E.Kenneth Mees. The newly constituted company soon introduced the first British panchromatic plates and filters. The introduction of Lumiere's Autochrome plates in 1907 prompted Wratten and Mees to take out a patent on a colour screen plate process of their own. The company also found work coating plates for other similar innovations. In 1912 the business was finally sold to George Eastman and Wratten and Mees joined Kodak Ltd at Harrow.[br]BibliographyWratten's early work on the action of alcohol on gelatine emulsions was described in a series of articles: 1877, Photographic News: 390, 49.1878, Photographic News: 121–3.1878, British Journal of Photography: 124–5.Further ReadingE.J.Wall, 1925, Three Colour Photography.C.E.K.Mees, 1961, From Dry Plates to Ektachrome Film, New York.JWBiographical history of technology > Wratten, Frederick Charles Luther

7 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 Lumière, Auguste
SUBJECT AREA: Photography, film and optics[br]b. 19 October 1862 Besançon, Franced. 10 April 1954 Lyon, France[br]French scientist and inventor.[br]Auguste and his brother Louis Lumière (b. 5 October 1864 Besançon, France; d. 6 June 1948 Bandol, France) developed the photographic plate-making business founded by their father, Charles Antoine Lumière, at Lyons, extending production to roll-film manufacture in 1887. In the summer of 1894 their father brought to the factory a piece of Edison kinetoscope film, and said that they should produce films for the French owners of the new moving-picture machine. To do this, of course, a camera was needed; Louis was chiefly responsible for the design, which used an intermittent claw for driving the film, inspired by a sewing-machine mechanism. The machine was patented on 13 February 1895, and it was shown on 22 March 1895 at the Société d'Encouragement pour l'In-dustrie Nationale in Paris, with a projected film showing workers leaving the Lyons factory. Further demonstrations followed at the Sorbonne, and in Lyons during the Congrès des Sociétés de Photographie in June 1895. The Lumières filmed the delegates returning from an excursion, and showed the film to the Congrès the next day. To bring the Cinématographe, as it was called, to the public, the basement of the Grand Café in the Boulevard des Capuchines in Paris was rented, and on Saturday 28 December 1895 the first regular presentations of projected pictures to a paying public took place. The half-hour shows were an immediate success, and in a few months Lumière Cinématographes were seen throughout the world.The other principal area of achievement by the Lumière brothers was colour photography. They took up Lippman's method of interference colour photography, developing special grainless emulsions, and early in 1893 demonstrated their results by lighting them with an arc lamp and projecting them on to a screen. In 1895 they patented a method of subtractive colour photography involving printing the colour separations on bichromated gelatine glue sheets, which were then dyed and assembled in register, on paper for prints or bound between glass for transparencies. Their most successful colour process was based upon the colour-mosaic principle. In 1904 they described a process in which microscopic grains of potato starch, dyed red, green and blue, were scattered on a freshly varnished glass plate. When dried the mosaic was coated with varnish and then with a panchromatic emulsion. The plate was exposed with the mosaic towards the lens, and after reversal processing a colour transparency was produced. The process was launched commercially in 1907 under the name Autochrome; it was the first fully practical single-plate colour process to reach the public, remaining on the market until the 1930s, when it was followed by a film version using the same principle.Auguste and Louis received the Progress Medal of the Royal Photographic Society in 1909 for their work in colour photography. Auguste was also much involved in biological science and, having founded the Clinique Auguste Lumière, spent many of his later years working in the physiological laboratory.[br]Further ReadingGuy Borgé, 1980, Prestige de la photographie, Nos. 8, 9 and 10, Paris.

9 Sutton, Thomas
SUBJECT AREA: Photography, film and optics[br]b. 1819 Englandd. 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.JW / BC -
10 Muybridge, Eadweard
SUBJECT AREA: Photography, film and optics[br]b. 9 April 1830 Kingston upon Thames, Englandd. 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.[br]Bibliography1887, Animal Locomotion, Philadelphia.1893, Descriptive Zoopraxography, Pennsylvania. 1899, Animals in Motion, London.1901, The Human Figure in Motion, London.Further Reading1973, Eadweard Muybridge: The Stanford Years, Stanford.G.Hendricks, 1975, Muybridge: The Father of the Motion Picture, New York.

11 Meisenbach, Georg
SUBJECT AREA: Paper and printing[br]b. 1841 Nuremberg, Germanyd. 12 December 1912 Munich, Germany[br]German engraver, inventor of the first commercially exploitable halftone printing process.[br]Trained in Nuremberg as a copper-plate engraver, Meisenbach moved to Munich in 1873 and established the first zincographic engraving business in Germany. In 1879 he began experimenting with halftone reproductions and in May 1882 he took out a German patent which described a single-line screen made from the proof of an engraved plate ruled with lines. The screen was then placed before a photographic positive of a picture and the two were photographed together. Approximately half-way through the exposure the screen was turned 90 degrees so that the lines crossed. A halftone negative was thus produced, from which could be made a zinc printing block. The full details of the process were not revealed in the patent so that trade competition would be limited. It was the first commercially practicable halftone process. Ill health forced Meisenbach to retire from the business in 1891, by which time his process was being superseded by Ives's cross-line process.[br]BibliographyMay 1882, German patent no. 22,444 (halftone printing process). 1882, British patent no. 2,156.Further ReadingJ.M.Eder, 1945, History of Photography, trans.

13 Anschütz, Ottomar
SUBJECT AREA: Photography, film and optics[br]b. 1846 Lissa, Prussia (now Leszno, Poland) d. 1907[br]German photographer, chronophotographer ana inventor.[br]The son of a commercial photographer, Anschütz entered the business in 1868 and developed an interest in the process of instantaneous photography. The process was very difficult with the contemporary wet-plate process, but with the introduction of the much faster dry plates in the late 1870s he was able to make progress. Anschütz designed a focal plane shutter capable of operating at speeds up to 1/1000 of a second in 1883, and patented his design in 1888. it involved a vertically moving fabric roller-blind that worked at a fixed tension but had a slit the width of which could be adjusted to alter the exposure time. This design was adopted by C.P.Goerz, who from 1890 manufactures a number of cameras that incorporated it.Anschütz's action pictures of flying birds and animals attracted the attention of the Prussian authorities, and in 1886 the Chamber of Deputies authorized financial support for him to continue his work, which had started at the Hanover Military Institute in October 1885. Inspired by the work of Eadweard Muybridge in America, Anschütz had set up rows of cameras whose focal-plane shutters were released in sequence by electromagnets, taking twenty-four pictures in about three-quarters of a second. He made a large number of studies of the actions of people, animals and birds, and at the Krupp artillery range at Meppen, near Essen, he recorded shells in flight. His pictures were reproduced, and favourably commented upon, in scientific and photographic journals.To bring the pictures to the public, in 1887 he created the Electro-Tachyscope. The sequence negatives were printed as 90 x 120 mm transparencies and fixed around the circumference of a large steel disc. This was rotated in front of a spirally wound Geissler tube, which produced a momentary brilliant flash of light when a high voltage from an induction coil was applied to it, triggered by contacts on the steel disc. The flash duration, about 1/1000 of a second, was so short that it "froze" each picture as it passed the tube. The pictures succeeded each other at intervals of about 1/30 of a second, and the observer saw an apparently continuously lit moving picture. The Electro-Tachyscope was shown publicly in Berlin at the Kulturministerium from 19 to 21 March 1887; subsequently Siemens \& Halske manufactured 100 machines, which were shown throughout Europe and America in the early 1890s. From 1891 his pictures were available for the home in the form of the Tachyscope viewer, which used the principle of the zoetrope: sequence photographs were printed on long strips of thin card, perforated with narrow slots between the pictures. Placed around the circumference of a shallow cylinder and rotated, the pictures could be seen in life-like movement when viewed through the slots.In November 1894 Anschütz displayed a projector using two picture discs with twelve images each, which through a form of Maltese cross movement were rotated intermittently and alternately while a rotating shutter allowed each picture to blend with the next so that no flicker occurred. The first public shows, given in Berlin, were on a screen 6×8 m (20×26 ft) in size. From 22 February 1895 they were shown regularly to audiences of 300 in a building on the Leipzigstrasse; they were the first projected motion pictures seen in Germany.[br]Further ReadingJ.Deslandes, 1966, Histoire comparée du cinéma, Vol. I, Paris.

16 Edison, Thomas Alva
SUBJECT AREA: Architecture and building, Automotive engineering, Electricity, Electronics and information technology, Metallurgy, Photography, film and optics, Public utilities, Recording, Telecommunications[br]b. 11 February 1847 Milan, Ohio, USAd. 18 October 1931 Glenmont[br]American inventor and pioneer electrical developer.[br]He was the son of Samuel Edison, who was in the timber business. His schooling was delayed due to scarlet fever until 1855, when he was 8½ years old, but he was an avid reader. By the age of 14 he had a job as a newsboy on the railway from Port Huron to Detroit, a distance of sixty-three miles (101 km). He worked a fourteen-hour day with a stopover of five hours, which he spent in the Detroit Free Library. He also sold sweets on the train and, later, fruit and vegetables, and was soon making a profit of $20 a week. He then started two stores in Port Huron and used a spare freight car as a laboratory. He added a hand-printing press to produce 400 copies weekly of The Grand Trunk Herald, most of which he compiled and edited himself. He set himself to learn telegraphy from the station agent at Mount Clements, whose son he had saved from being run over by a freight car.At the age of 16 he became a telegraphist at Port Huron. In 1863 he became railway telegraphist at the busy Stratford Junction of the Grand Trunk Railroad, arranging a clock with a notched wheel to give the hourly signal which was to prove that he was awake and at his post! He left hurriedly after failing to hold a train which was nearly involved in a head-on collision. He usually worked the night shift, allowing himself time for experiments during the day. His first invention was an arrangement of two Morse registers so that a high-speed input could be decoded at a slower speed. Moving from place to place he held many positions as a telegraphist. In Boston he invented an automatic vote recorder for Congress and patented it, but the idea was rejected. This was the first of a total of 1180 patents that he was to take out during his lifetime. After six years he resigned from the Western Union Company to devote all his time to invention, his next idea being an improved ticker-tape machine for stockbrokers. He developed a duplex telegraphy system, but this was turned down by the Western Union Company. He then moved to New York.Edison found accommodation in the battery room of Law's Gold Reporting Company, sleeping in the cellar, and there his repair of a broken transmitter marked him as someone of special talents. His superior soon resigned, and he was promoted with a salary of $300 a month. Western Union paid him $40,000 for the sole rights on future improvements on the duplex telegraph, and he moved to Ward Street, Newark, New Jersey, where he employed a gathering of specialist engineers. Within a year, he married one of his employees, Mary Stilwell, when she was only 16: a daughter, Marion, was born in 1872, and two sons, Thomas and William, in 1876 and 1879, respectively.He continued to work on the automatic telegraph, a device to send out messages faster than they could be tapped out by hand: that is, over fifty words per minute or so. An earlier machine by Alexander Bain worked at up to 400 words per minute, but was not good over long distances. Edison agreed to work on improving this feature of Bain's machine for the Automatic Telegraph Company (ATC) for $40,000. He improved it to a working speed of 500 words per minute and ran a test between Washington and New York. Hoping to sell their equipment to the Post Office in Britain, ATC sent Edison to England in 1873 to negotiate. A 500-word message was to be sent from Liverpool to London every half-hour for six hours, followed by tests on 2,200 miles (3,540 km) of cable at Greenwich. Only confused results were obtained due to induction in the cable, which lay coiled in a water tank. Edison returned to New York, where he worked on his quadruplex telegraph system, tests of which proved a success between New York and Albany in December 1874. Unfortunately, simultaneous negotiation with Western Union and ATC resulted in a lawsuit.Alexander Graham Bell was granted a patent for a telephone in March 1876 while Edison was still working on the same idea. His improvements allowed the device to operate over a distance of hundreds of miles instead of only a few miles. Tests were carried out over the 106 miles (170 km) between New York and Philadelphia. Edison applied for a patent on the carbon-button transmitter in April 1877, Western Union agreeing to pay him $6,000 a year for the seventeen-year duration of the patent. In these years he was also working on the development of the electric lamp and on a duplicating machine which would make up to 3,000 copies from a stencil. In 1876–7 he moved from Newark to Menlo Park, twenty-four miles (39 km) from New York on the Pennsylvania Railway, near Elizabeth. He had bought a house there around which he built the premises that would become his "inventions factory". It was there that he began the use of his 200- page pocket notebooks, each of which lasted him about two weeks, so prolific were his ideas. When he died he left 3,400 of them filled with notes and sketches.Late in 1877 he applied for a patent for a phonograph which was granted on 19 February 1878, and by the end of the year he had formed a company to manufacture this totally new product. At the time, Edison saw the device primarily as a business aid rather than for entertainment, rather as a dictating machine. In August 1878 he was granted a British patent. In July 1878 he tried to measure the heat from the solar corona at a solar eclipse viewed from Rawlins, Wyoming, but his "tasimeter" was too sensitive.Probably his greatest achievement was "The Subdivision of the Electric Light" or the "glow bulb". He tried many materials for the filament before settling on carbon. He gave a demonstration of electric light by lighting up Menlo Park and inviting the public. Edison was, of course, faced with the problem of inventing and producing all the ancillaries which go to make up the electrical system of generation and distribution-meters, fuses, insulation, switches, cabling—even generators had to be designed and built; everything was new. He started a number of manufacturing companies to produce the various components needed.In 1881 he built the world's largest generator, which weighed 27 tons, to light 1,200 lamps at the Paris Exhibition. It was later moved to England to be used in the world's first central power station with steam engine drive at Holborn Viaduct, London. In September 1882 he started up his Pearl Street Generating Station in New York, which led to a worldwide increase in the application of electric power, particularly for lighting. At the same time as these developments, he built a 1,300yd (1,190m) electric railway at Menlo Park.On 9 August 1884 his wife died of typhoid. Using his telegraphic skills, he proposed to 19-year-old Mina Miller in Morse code while in the company of others on a train. He married her in February 1885 before buying a new house and estate at West Orange, New Jersey, building a new laboratory not far away in the Orange Valley.Edison used direct current which was limited to around 250 volts. Alternating current was largely developed by George Westinghouse and Nicola Tesla, using transformers to step up the current to a higher voltage for long-distance transmission. The use of AC gradually overtook the Edison DC system.In autumn 1888 he patented a form of cinephotography, the kinetoscope, obtaining film-stock from George Eastman. In 1893 he set up the first film studio, which was pivoted so as to catch the sun, with a hinged roof which could be raised. In 1894 kinetoscope parlours with "peep shows" were starting up in cities all over America. Competition came from the Latham Brothers with a screen-projection machine, which Edison answered with his "Vitascope", shown in New York in 1896. This showed pictures with accompanying sound, but there was some difficulty with synchronization. Edison also experimented with captions at this early date.In 1880 he filed a patent for a magnetic ore separator, the first of nearly sixty. He bought up deposits of low-grade iron ore which had been developed in the north of New Jersey. The process was a commercial success until the discovery of iron-rich ore in Minnesota rendered it uneconomic and uncompetitive. In 1898 cement rock was discovered in New Village, west of West Orange. Edison bought the land and started cement manufacture, using kilns twice the normal length and using half as much fuel to heat them as the normal type of kiln. In 1893 he met Henry Ford, who was building his second car, at an Edison convention. This started him on the development of a battery for an electric car on which he made over 9,000 experiments. In 1903 he sold his patent for wireless telegraphy "for a song" to Guglielmo Marconi.In 1910 Edison designed a prefabricated concrete house. In December 1914 fire destroyed three-quarters of the West Orange plant, but it was at once rebuilt, and with the threat of war Edison started to set up his own plants for making all the chemicals that he had previously been buying from Europe, such as carbolic acid, phenol, benzol, aniline dyes, etc. He was appointed President of the Navy Consulting Board, for whom, he said, he made some forty-five inventions, "but they were pigeonholed, every one of them". Thus did Edison find that the Navy did not take kindly to civilian interference.In 1927 he started the Edison Botanic Research Company, founded with similar investment from Ford and Firestone with the object of finding a substitute for overseas-produced rubber. In the first year he tested no fewer than 3,327 possible plants, in the second year, over 1,400, eventually developing a variety of Golden Rod which grew to 14 ft (4.3 m) in height. However, all this effort and money was wasted, due to the discovery of synthetic rubber.In October 1929 he was present at Henry Ford's opening of his Dearborn Museum to celebrate the fiftieth anniversary of the incandescent lamp, including a replica of the Menlo Park laboratory. He was awarded the Congressional Gold Medal and was elected to the American Academy of Sciences. He died in 1931 at his home, Glenmont; throughout the USA, lights were dimmed temporarily on the day of his funeral.[br]Principal Honours and DistinctionsMember of the American Academy of Sciences.
