101 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.

102 Voigt, Paul Gustavus Adolphus Helmuth
[br]b. 9 December 1901 Forest Hill, London, Englandd. 9 February 1981 Brighton, Ontario, Canada[br]English/Canadian electronics engineer, developer of electromechanical recording and reproductions systems, amplifiers and loudspeakers.[br]He received his education at Dulwich College and in 1922 graduated with a BSc from University College, London. He had an early interest in the application of valve amplifiers, and after graduating he was employed by J.E.Hough, Edison Bell Works, to develop a line of radio-receiving equipment. However, he became interested in the mechanical (and later electrical) side of recording and from 1925 developed principles and equipment. In particular he developed capacitor microphones, not only for in-house work but also commercially, until the mid-1930s. The Edison Bell company did not survive the Depression and closed in 1933. Voigt founded his own company, Voigt Patents Ltd, concentrating on loudspeakers for cinemas and developing horn loudspeakers for domestic use. During the Second World War he continued to develop loudspeaker units and gramophone pick-ups, and in 1950 he emigrated to Toronto, Canada, but his company closed. Voigt taught electronics, and from 1960 to 1969 he was employed by the Radio Regulations Laboratory in Ottawa. After retirement he worked with theoretical cosmology and fundamental interactions.[br]BibliographyMost of Voigt's patents are concerned with improvements in the magnetic circuit in dynamic loudspeakers and centring devices for diaphragms. However, UK patent nos. 278,098, 404,037 and 447,749 may be regarded as particularly relevant. In 1940 Voigt contributed a remarkable paper on the principles of equalization in mechanical recording: "Getting the best from records, part 1—the recording characteristic", Wireless World (February): 141–4.Further ReadingPersonal accounts of experiences with Voigt may be found in "Paul Voigt's contribution to Audio", British Kinematography Sound and Television (October 1970): 316–27, which also includes a list of his patents.GB-NBiographical history of technology > Voigt, Paul Gustavus Adolphus Helmuth

103 Whinfield, John Rex
[br]b. 16 February 1901 Sutton, Surrey, Englandd. 6 July 1955 Dorking, Surrey, England[br]English inventor ofTerylene.[br]Whinfield was educated at Merchant Taylors' School and Caius College, Cambridge, where he studied chemistry. Before embarking on his career as a research chemist, he worked as an un-paid assistant to the chemist C.F. Cross, who had taken part in the discovery of rayon. Whinfield then joined the Calico Printers' Association. There his interest was aroused by the discovery of nylon by W.H. Carothers to seek other polymers which could be produced in fibre form, usable by the textile industries. With his colleague J.T. Dickson, he discovered in 1941 that a polymerized condensate of terephthalic acid and ethylene glycol, polyethylene terephthgal-late, could be drawn into strong fibres. Whinfield and Dickson filed a patent application in the same year, but due to war conditions it was not published until 1946. The Ministry of Supply considered that the new material might have military applications and undertook further research and development. Its industrial and textile possibilities were evaluated by Imperial Chemical Industries (ICI) in 1943 and "Terylene", as it came to be called, was soon recognized as being as important as nylon.In 1946, Dupont acquired rights to work the Calico Printers' Association patent in the USA and began large-scale manufacture in 1954, marketing the product under the name "Dacron". Meanwhile ICI purchased world rights except for the USA and reached the large-scale manufacture stage in 1955. A new branch of the textile industry has grown up from Whinfield's discovery: he lived to see most people in the western world wearing something made of Terylene. It was one of the major inventions of the twentieth century, yet Whinfield, perhaps because he published little, received scant recognition, apart from the CBE in 1954.[br]Principal Honours and DistinctionsCBE 1954.Further ReadingObituary, 1966, The Times (7 July).Obituary, 1967, Chemistry in Britain 3:26.J.Jewkes, D.Sawers and R.Stillerman, 1969, The Sources of Invention, 2nd edn, London: Macmillan.LRD -
104 Yarrow, Sir Alfred Fernandez
SUBJECT AREA: Ports and shipping[br]b. 13 January 1842 London, Englandd. 24 January 1932 London, England[br]English shipbuilder, naval architect, engineer and philanthropist.[br]At the conclusion of his schooling in the South of England, Yarrow became an indentured apprentice to the Thames engine-builder Ravenhill. During this five-year period various incidents and meetings sharpened his interest in scientific matters and he showed the skills that in later years were to be so beneficial to shipbuilding. For two years he acted as London representative for Ravenhill before joining up with a Mr Hedley to form a shipyard on the Isle of Dogs. The company lasted from 1868 until 1875 and in that period produced 350 small launches and other craft. This massive output enabled Yarrow to gain confidence in many aspects of ship design. Within two years of setting out on his own he built his first ship for the Royal Navy: a torpedo boat, then at the cutting edge of technology.In the early 1890s the company was building watertube boilers and producing destroyers with speeds in excess of 27 knots (50 km/h); it built the Russian destroyer Sokol, did pioneering work with aluminium and with high-tensile steels and worked on shipboard equipment to nullify vibrational effects. With the closure of most of the Thames shipyards and the run-down in skilled labour, Yarrow decided that the shipyard must move to some other part of the United Kingdom. After careful deliberation a green field site to the west of Glasgow was chosen, and in 1908 their first Clyde-built destroyer was launched. The company expanded, more building berths were arranged, boiler construction was developed and over the years they became recognized as specialists in smaller highspeed craft and in "knock down" ships for other parts of the world.Yarrow retired in 1913, but at the commencement of the First World War he returned to help the yard produce, in four years, twenty-nine destroyers with speeds of up to 40 knots (74 km/h). At the end of hostilities he gave of his time and money to many charities, including those for ex-servicemen. He left a remarkable industrial organization which remains to this day the most prolific builder of surface craft for the Royal Navy.[br]Principal Honours and DistinctionsCreated Baronet 1916.

As the subsequent clause οὐδὲ δωρεὰν ἄρτον ἐφάγομαν παρά τινος indicates, Paul conforms to societal proprieties and did not act as though he were entitled to free sustenance; to support his claim, he states that he ‘worked night and day so as not to be a burden to them’. Cp. 1 Cor 10:31–11:1 (for the Gr-Rom. perspective, s. Aristot. EN 4, 15–18).
