15 Duddell, William du Bois
SUBJECT AREA: Electricity[br]b. 1872 Kensington, London, Englandd. 4 November 1917 London, England[br]English engineer, inventor of the first practical oscillograph.[br]After an education at the College of Stanislas, Cannes, Duddell served an apprenticeship with Davy Paxman of Colchester. Studying under Ayrton and Mather at the Central Technical College in South Kensington, he found the facilities for experimental work of exceptional value to him and remained there for some years. In 1897 Duddell produced a galvanometer which was sufficiently responsive to display an alternating-current wave-form. This instrument, with a coil carrying a mirror in the air gap of a powerful electromagnet, had a small periodic time. An oscillating mirror driven by a synchronous motor spread out the deflection on a time-scale. This development became the first commercial oscillograph and brought Duddell into prominence as a first-rate designer of special instruments. The Duddell oscillograph remained in use until after the Second World War, examples being used for recording short-circuit tests on high-power switchgear and other rapidly varying or transient phenomena. His next important work was to collaborate with Professor Marchant at Liverpool University to investigate the characteristics of the electric arc. This led to the suggestion that, coupled to a resonant circuit, the electric arc could form a generator of high-frequency currents. This arrangement was later developed by Poulson for wireless telegraphy. Duddell spent the last years of his life on government research as a member of the Admiralty Board of Inventions and Research and also of the Inventions Board of the Ministry of Munitions.[br]Principal Honours and DistinctionsCBE 1916.

16 Joubert, Jules François
SUBJECT AREA: Electricity[br]b. 1834 Tours, Franced. 1910 Paris, France[br]French physicist, investigator of alternating-current wave-forms.[br]Joubert became Professor of Physics in the Collège Rollin, Paris, in 1874, a position he held until 1888. He was at one time General Secretary of the Société Française de Physique. In collaboration with Pasteur he began studies into the theories of germs and bacteria. In 1880 Joubert carried out research on wave-forms in alternating-current arc-lighting circuits. Reinventing a method previously used by earlier experimenters, including Wheatstone, he was, by a mechanical sampling technique, able to determine the voltage at different points in the cycle. By using a rotating contact on the alternator shaft, the angular position of which could be varied, the whole of the wave-form could be delineated. This successful technique was widely used for some thirty years.[br]Bibliography1880, "Sur les courants alternatifs et la force électromotive de l'arc électrique", Journal of Physics 9:297–303 (describes his experiments).Further Reading"Investigation of alternating current arcs", Electrician (1880) 5:151–2 (a report on Joubert's method).V.J.Phillips, 1987, Waveforms, Bristol (an extensive account of early methods of wave-form observation).W.Bulloch, 1938, The History of Bacteriology, Oxford; 1979, repub.

17 Scott de Martinville, Edouard-Léon
SUBJECT AREA: Recording[br]b. 25 April 1817 Paris, Franced. 29 April 1879 Paris, France[br]French amateur phonetician, who developed a recorder for sound waves.[br]He was the descendant of a Scottish family who emigrated to France in 1688. He trained as a printer and later became a proof corrector in printing houses catering predominantly for scientific publishers. He became interested in shorthand systems and eventually turned his interest to making a permanent record of sounds in air. At the time it was already known (Young, Duhamel, Wertheim) to record vibrations of bodies. He made a theoretical study and deposited under sealed wrapper a note in the Académie des Sciences on 26 January 1857. He approached the scientific instrument maker Froment and was able to pay for the manufacture of one instrument due to support from the Société d'Encouragement à l'Industrie Nationale. This funding body obtained a positive report from the physicist Lissajous on 6 January 1858. A new model phonautograph was constructed in collaboration with the leading scientific instrument maker in Paris at the time, Rudolph Koenig, and a contract was signed in 1859. The instrument was a success, and Koenig published a collection of traces in 1864.Although the membrane was parallel to the rotating surface, a primitive lever system generated lateral movements of a bristle which scratched curves in a thin layer of lampblack on the rotating surface. The curves were not necessarily representative of the vibrations in the air. Scott did not imagine the need for reproducing a recorded sound; rather, his intention was to obtain a trace that would lend itself to mathematical analysis and visual recognition of sounds. Obviously the latter did not require the same degree of linearity as the former. When Scott learned that similar apparatus had been built independently in the USA, he requested that his sealed wrapper be opened on 15 July 1861 in order to prove his scientific priority. The contract with Koenig left Scott without influence over his instrument, and eventually he became convinced that everyone else, including Edison in the end, had stolen his invention. Towards the end of his life he became interested mainly in the history of printing, and he was involved in the publishing of a series of books about books.[br]Bibliography25 March 1857, amended 29 July 1859, French patent no. 31,470.Further ReadingP.Charbon, 1878, Scott de Martinville, Paris: Hifi Stereo, pp. 199–205 (a good biography produced at the time of the centenary of the Edison phonograph).V.J.Philips, 1987, Waveforms, Bristol: Adam Hilger, pp. 45–8 (provides a good account of the importance of his contributions to accurate measurements of temporal phenomena).GB-NBiographical history of technology > Scott de Martinville, Edouard-Léon
