4 Bayard, Hippolyte
SUBJECT AREA: Photography, film and optics[br]b. 1801 Breteuil-sur-Noye, France d. 1887[br]French photographer, inventor of an early direct positive paper process.[br]Educated as a notary's clerk, Bayard began his working life in Paris in the Ministry of Finance. His interest in art led him to investigations into the chemical action of light, and he began his experiments in 1837. In May 1839 Bayard described an original photographic process which produced direct positive images on paper. It was devised independently of Talbot and before details of Daguerre's process had been published. During the same period, similar techniques were announced by other investigators and Bayard became involved in a series of priority disputes. Bayard's photographs were well received when first exhibited, and examples survive to the present day. Because the process required long exposure times it was rarely practised, but Bayard is generally credited with being an independent inventor of photography.[br]Bibliography1840, Comptes rendus (24 February): 337 (the first published details of Bayard's process).Further ReadingH.Gernsheim and A.Gernsheim, 1969, The History of Photography, rev. edn, London.JW -
5 Fizeau, Armand Hippolyte Louis
SUBJECT AREA: Photography, film and optics[br]b. 23 September 1819 Paris, Franced. 18 September 1896 Nanteuil-le-Haudouin, France[br]French physicist who introduced early improvements to the daguerreotype process.[br]Fizeau's interest in photography was comparatively brief, but during this period he was at the forefront of French attempts to explore and exploit the potential of the recently announced daguerreotype process (see Daguerre). Fizeau is best remembered for his introduction in August 1840 of the practice of gold-toning daguerreotypes. This improvement not only helped protect the delicate surface of the plate from abrasion and tarnishing, but also enhanced the quality of the image. The technique was not patented and was immediately adopted by all daguerreotypists. Between 1839 and 1841, in association with Alfred Donné, Fizeau conducted experiments with the aim of converting daguerreotypes into printing plates. Prints from two of his plates were published in 1842, but the technique was never widely practised. In association with J.B.Léon Foucault, Fizeau discovered the reciprocity failure of daguerreotypes, and the same partnership produced what were probably the first daguerreotypes of the sun. Fizeau is best known in physics for making the first accurate determination of the speed of light, in 1849.[br]Further ReadingW.H.Thornthwaite, 1843, Photographic Manipulation, London (provides details of Fizeau's gold-toning process).H.Gernsheim and A.Gernsheim, 1969, The History of Photography, rev. edn, London (a more general account of Fizeau's contributions to photography).JWBiographical history of technology > Fizeau, Armand Hippolyte Louis

6 Mouriés, Hippolyte Mège
SUBJECT AREA: Agricultural and food technology[br]b. 24 October 1817 Draguignan, Franced. 1880 France[br]French inventor of margarine.[br]The son of a schoolmaster. Mouriés became a chemist's assistant in his home town at the age of 16. He then spent a period of training in Aix-enProvence, and in 1838 he moved to Paris, where he became Assistant to the Resident Pharmacist at the Hotel Dieu Hospital. He stayed there until 1846 but never sat his final exams. His main success during this period was with the drug Copahin, which was used against syphilis; he invented an oral formulation of the drug by treating it with nitric acid. In the 1840s he took out various patents relating to tanning and to sugar extraction, and in the 1850s he turned his attention to food research. He developed a health chocolate with his calcium phosphate protein, and also developed a method that made it possible to gain 14 per cent more white bread from a given quantity of wheat. He lectured on this process in Berlin and Brussels and was awarded two gold medals. After 1862 he concentrated his research on fats. His margarine process was based on the cold saponification of milk in fat emulsions and was patented in both France and Britain in 1869. These experiments were carried out at the Ferme Impériale de La Faisanderie in Vincennes, the personal property of the Emperor, and it is therefore likely that they were State-funded. He sold his knowledge to the Dutch firm Jurgens in 1871, and between 1873 and 1874 he also sold his British, American and Prussian rights. His final patent, in 1875, was for canned meat.[br]Principal Honours and DistinctionsNapoleon III awarded him the Légion d'honneur for his work on wheat and bread.Further ReadingJ.H.van Stuyvenberg (ed.), Margarine: An Economic, Social and Scientific History, 1869–1969 (provides a brief outline of the life of Mouriés in a comprehensive history of his discovery).APBiographical history of technology > Mouriés, Hippolyte Mège

7 Pixii, Antoine Hippolyte
SUBJECT AREA: Electricity[br]b. 1808 Franced. 1835[br]French instrument maker who devised the first machine to incorporate the basic elements of a modern electric generator.[br]Mechanical devices to transform energy from a mechanical to an electrical form followed shortly after Faraday's discovery of induction. One of the earliest was Pixii's magneto generator. Pixii had been an instrument maker to Arago and Ampère for a number of years and his machine was first announced to the Academy of Sciences in Paris in September 1832. In this hand-driven generator a permanent magnet was rotated in close proximity to two coils on soft iron cores, producing an alternating current. Subsequently Pixii adapted to a larger version of his machine a "see-saw" switch or commutator devised by Ampère, in order to obtain a unidirectional current. The machine provided a current similar to that obtained with a chemical cell and was capable of decomposing water into oxygen and hydrogen. It was the prototype of many magneto-electric machines which followed.[br]Principal Honours and DistinctionsAcademy of Sciences, Paris, Gold Medal 1832.Further ReadingB.Bowers, 1982, A History of Electric Light and Power, London, pp. 70–2 (describes the development of Pixii's generator).C.Jackson, 1833, "Notice of the revolving electric magnet of Mr Pixii of Paris", American Journal of Science 24:146–7.GWBiographical history of technology > Pixii, Antoine Hippolyte

14 Gramme, Zénobe Théophile
[br]b. 4 April 1826 Jehay-Bodignée, Belgiumd. 20 January 1901 Bois de Colombes, Paris, France[br]Belgian engineer whose improvements to the dynamo produced a machine ready for successful commercial exploitation.[br]Gramme trained as a carpenter and showed an early talent for working with machinery. Moving to Paris he found employment in the Alliance factory as a model maker. With a growing interest in electricity he left to become an instrument maker with Heinrich Daniel Rühmkorff. In 1870 he patented the uniformly wound ring-armature dynamo with which his name is associated. Together with Hippolyte Fontaine, in 1871 Gramme opened a factory to manufacture his dynamos. They rapidly became a commercial success for both arc lighting and electrochemical purposes, international publicity being achieved at exhibitions in Vienna, Paris and Philadelphia. It was the realization that a Gramme machine was capable of running as a motor, i.e. the reversibility of function, that illustrated the entire concept of power transmission by electricity. This was first publicly demonstrated in 1873. In 1874 Gramme reduced the size and increased the efficiency of his generators by relying completely on the principle of self-excitation. It was the first practical machine in which were combined the features of continuity of commutation, self-excitation, good lamination of the armature core and a reasonably good magnetic circuit. This dynamo, together with the self-regulating arc lamps then available, made possible the innumerable electric-lighting schemes that followed. These were of the greatest importance in demonstrating that electric lighting was a practical and economic means of illumination. Gramme also designed an alternator to operate Jablochkoff candles. For some years he took an active part in the operations of the Société Gramme and also experimented in his own workshop without collaboration, but made no further contribution to electrical technology.[br]Principal Honours and DistinctionsKnight Commander, Order of Leopold of Belgium 1897.

15 Lenoir, Jean Joseph Etienne
SUBJECT AREA: Metallurgy, Railways and locomotives, Steam and internal combustion engines, Telecommunications[br]b. 1822 Mussey-la-Ville, Belgiumd. 1900 Verenna Saint-Hildar, France[br]Belgian (naturalized French in 1870) inventor of internal combustion engines, an electroplating process and railway telegraphy systems.[br]Leaving his native village for Paris at the age of 16, Lenoir became a metal enameller. Experiments with various electroplating processes provided a useful knowledge of electricity that showed in many of his later ideas. Electric ignition, although somewhat unreliable, was a feature of the Lenoir gas engine which appeared in 1860. Resembling the steam engine of the day, Lenoir engines used a non-compression cycle of operations, in which the gas-air mixture of about atmospheric pressure was being ignited at one-third of the induction stroke. The engines were double acting. About five hundred of Lenoir's engines were built, mostly in Paris by M.Hippolyte Marinoni and by Lefébvre; the Reading Ironworks in England built about one hundred. Many useful applications of the engine are recorded, but the explosive shock that occurred on ignition, together with the unreliable ignition systems, prevented large-scale acceptance of the engine in industry. However, Lenoir's effort and achievements stimulated much discussion, and N.A. Otto is reported to have carried out his first experiments on a Lenoir engine.[br]Principal Honours and DistinctionsAcadémie des Sciences Prix Montyon Prize 1870.
