126 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.

127 Heaviside, Oliver
[br]b. 18 May 1850 London, Englandd. 2 February 1925 Torquay, Devon, England[br]English physicist who correctly predicted the existence of the ionosphere and its ability to reflect radio waves.[br]Brought up in poor, almost Dickensian, circumstances, at the age of 13 years Heaviside, a nephew by marriage of Sir Charles Wheatstone, went to Camden House Grammar School. There he won a medal for science, but he was forced to leave because his parents could not afford the fees. After a year of private study, he began his working life in Newcastle in 1870 as a telegraph operator for an Anglo-Dutch cable company, but he had to give up after only four years because of increasing deafness. He therefore proceeded to spend his time studying theoretical aspects of electrical transmission and communication, and moved to Devon with his parents in 1889. Because the operation of many electrical circuits involves transient phenomena, he found it necessary to develop what he called operational calculus (which was essentially a form of the Laplace transform calculus) in order to determine the response to sudden voltage and current changes. In 1893 he suggested that the distortion that occurred on long-distance telephone lines could be reduced by adding loading coils at regular intervals, thus creating a matched-transmission line. Between 1893 and 1912 he produced a series of writings on electromagnetic theory, in one of which, anticipating a conclusion of Einstein's special theory of relativity, he put forward the idea that the mass of an electric charge increases with its velocity. When it was found that despite the curvature of the earth it was possible to communicate over very great distances using radio signals in the so-called "short" wavebands, Heaviside suggested the presence of a conducting layer in the ionosphere that reflected the waves back to earth. Since a similar suggestion had been made almost at the same time by Arthur Kennelly of Harvard, this layer became known as the Kennelly-Heaviside layer.[br]Principal Honours and DistinctionsFRS 1891.

128 Woodbury, Walter Bentley
SUBJECT AREA: Photography, film and optics[br]b. 1834 Manchester, Englandd. 1885 Margate, Kent, England[br]English photographer, inventor of the Woodburytype process.[br]Having been apprenticed to be an engineer, Woodbury left England in 1851 to seek his fortune in the Australian gold-fields. Like many others, he failed, and after a series of transient jobs found a post as Draughtsman at the Melbourne Waterworks. He then went on to Java, where he practised wet-collodion photography before returning to England finally in 1863. Woodbury settled in Birmingham, where like most contemporary photographers he was concerned to find a solution to the troublesome problem of fading prints. He began working the carbon process, and in 1866 and 1867 took out a series of patents which were to lead to the development of the process that took his name. Woodburytypes were continuous-tone prints of high quality that could be mass produced more cheaply than the traditional silver print. This was an important innovation and Woodburytypes were extensively used for quality book illustrations until the introduction of more versatile photomechanical processes in the 1890s. In all, Woodbury took out twenty patents between 1864 and 1884, some relating to a wide range of photographic devices. He was still working to simplify the Woodburytype process when he died from an overdose of laudanum.[br]BibliographyWoodbury took out a series of patents on his process, the most significant being: 23 September 1864, British patent no. 2,338; 12 January 1866, British patent no. 105; 11 February 1866, British patent no. 505; 8 May 1866, British patent no. 1,315; 24 July 1866, British patent no. 1,918.Further ReadingG.Tissandier, 1876, A History and Handbook of Photography, trans.
