121 Steinheil, Carl August von
[br]b. 1801 Roppoltsweiler, Alsaced. 1870 Munich, Germany[br]German physicist, founder of electromagnetic telegraphy in Austria, and photographic innovator and lens designer.[br]Steinheil studied under Gauss at Göttingen and Bessel at Königsberg before jointing his parents at Munich. There he concentrated on optics before being appointed Professor of Physics and Mathematics at the University of Munich in 1832. Immediately after the announcement of the first practicable photographic processes in 1839, he began experiments on photography in association with another professor at the University, Franz von Kobell. Steinheil is reputed to have made the first daguerreotypes in Germany; he certainly constructed several cameras of original design and suggested minor improvements to the daguerreotype process. In 1849 he was employed by the Austrian Government as Head of the Department of Telegraphy in the Ministry of Commerce. Electromagnetic telegraphy was an area in which Steinheil had worked for several years previously, and he was now appointed to supervise the installation of a working telegraphic system for the Austrian monarchy. He is considered to be the founder of electromagnetic telegraphy in Austria and went on to perform a similar role in Switzerland.Steinheil's son, Hugo Adolph, was educated in Munich and Augsburg but moved to Austria to be with his parents in 1850. Adolph completed his studies in Vienna and was appointed to the Telegraph Department, headed by his father, in 1851. Adolph returned to Munich in 1852, however, to concentrate on the study of optics. In 1855 the father and son established the optical workshop which was later to become the distinguished lens-manufacturing company C.A. Steinheil Söhne. At first the business confined itself almost entirely to astronomical optics, but in 1865 the two men took out a joint patent for a wide-angle photographic lens claimed to be free of distortion. The lens, called the "periscopic", was not in fact free from flare and not achromatic, although it enjoyed some reputation at the time. Much more important was the achromatic development of this lens that was introduced in 1866 and called the "Aplanet"; almost simultaneously a similar lens, the "Rapid Rentilinear", was introduced by Dallmeyer in England, and for many years lenses of this type were fitted as the standard objective on most photographic cameras. During 1866 the elder Steinheil relinquished his interest in lens manufacturing, and control of the business passed to Adolph, with administrative and financial affairs being looked after by another son, Edward. After Carl Steinheil's death Adolph continued to design and market a series of high-quality photographic lenses until his own death.[br]Further ReadingJ.M.Eder, 1945, History of Photography, trans.

123 Marey, Etienne-Jules
[br]b. 5 March 1830 Beaune, Franced. 15 May 1904 Paris, France[br]French physiologist and pioneer of chronophotography.[br]At the age of 19 Marey went to Paris to study medicine, becoming particularly interested in the problems of the circulation of the blood. In an early communication to the Académie des Sciences he described a much improved device for recording the pulse, the sphygmograph, in which the beats were recorded on a smoked plate. Most of his subsequent work was concerned with methods of recording movement: to study the movement of the horse, he used pneumatic sensors on each hoof to record traces on a smoked drum; this device became known as the Marey recording tambour. His attempts to study the wing movements of a bird in flight in the same way met with limited success since the recording system interfered with free movement. Reading in 1878 of Muybridge's work in America using sequence photography to study animal movement, Marey considered the use of photography himself. In 1882 he developed an idea first used by the astronomer Janssen: a camera in which a series of exposures could be made on a circular photographic plate. Marey's "photographic gun" was rifle shaped and could expose twelve pictures in approximately one second on a circular plate. With this device he was able to study wing movements of birds in free flight. The camera was limited in that it could record only a small number of images, and in the summer of 1882 he developed a new camera, when the French government gave him a grant to set up a physiological research station on land provided by the Parisian authorities near the Porte d'Auteuil. The new design used a fixed plate, on which a series of images were recorded through a rotating shutter. Looking rather like the results provided by a modern stroboscope flash device, the images were partially superimposed if the subject was slow moving, or separated if it was fast. His human subjects were dressed all in white and moved against a black background. An alternative was to dress the subject in black, with highly reflective strips and points along limbs and at joints, to produce a graphic record of the relationships of the parts of the body during action. A one-second-sweep timing clock was included in the scene to enable the precise interval between exposures to be assessed. The fixed-plate cameras were used with considerable success, but the number of individual records on each plate was still limited. With the appearance of Eastman's Kodak roll-film camera in France in September 1888, Marey designed a new camera to use the long rolls of paper film. He described the new apparatus to the Académie des Sciences on 8 October 1888, and three weeks later showed a band of images taken with it at the rate of 20 per second. This camera and its subsequent improvements were the first true cinematographic cameras. The arrival of Eastman's celluloid film late in 1889 made Marey's camera even more practical, and for over a decade the Physiological Research Station made hundreds of sequence studies of animals and humans in motion, at rates of up to 100 pictures per second. Marey pioneered the scientific study of movement using film cameras, introducing techniques of time-lapse, frame-by-frame and slow-motion analysis, macro-and micro-cinematography, superimposed timing clocks, studies of airflow using smoke streams, and other methods still in use in the 1990s. Appointed Professor of Natural History at the Collège de France in 1870, he headed the Institut Marey founded in 1898 to continue these studies. After Marey's death in 1904, the research continued under the direction of his associate Lucien Bull, who developed many new techniques, notably ultra-high-speed cinematography.[br]Principal Honours and DistinctionsForeign member of the Royal Society 1898.

124 Waterhouse, Major-General James
SUBJECT AREA: Photography, film and optics[br]b. 1841d. 28 September 1922[br]English military man and photographer.[br]Waterhouse spent most of his career in the Indian Army. In 1861–2 he was commissioned to photograph the tribes of central India, and over the next few years visited many parts of the subcontinent. In November 1866, after working for five months in the Great Trigonometrical Survey learning the process of photozincography (an early photomechanical process used chiefly for map making), he took charge of photographic operations at the Surveyor-General's office in Calcutta, a post he held until retiring in 1897. During this time he developed many improvements in the photomechanical methods used for reproduction in his office. He also experimented with methods of colour-sensitizing photographic materials, experimenting with eosine dye and publishing in 1875 the fact that this made silver halide salts sensitive to yellow light. He also discovered that gelatine dry plates could be made sensitive to red and infra-red illumination by treatment with alizarine blue solution.He continued his researches upon his retirement and return to England in 1897, and made a special study of the early history of the photographic process. His work on dye sensitizing brought him the Progress Medal of the Royal Photographic Society, and the Vienna Photographic Society awarded him the Voigtländer Medal for researches in scientific photography. One invention often erroneously attributed to him is the Waterhouse stop, the use of a series of perforated plates as a means of adjusting the aperture of a photographic lens. This was described in 1858 by a John Waterhouse, being his only contribution to photography.BCBiographical history of technology > Waterhouse, Major-General James
