45 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.

46 Jansky, Karl Guthe
[br]b. 22 October 1905 Norman, Oklahoma, USAd. 14 February 1950 Red Bank, New Jersey, USA[br]American radio engineer who discovered stellar radio emission.[br]Following graduation from the University of Wisconsin in 1928 and a year of postgraduate study, Jansky joined Bell Telephone Laboratories in New Jersey with the task of establishing the source of interference to telephone communications by radio. To this end he constructed a linear-directional short-wave antenna and eventually, in 1931, he concluded that the interference actually came from the stars, the major source being the constellation Sagittarius in the direction of the centre of the Milky Way. Although he continued to study the propagation of short radio waves and the nature of observed echoes, it was left to others to develop the science of radioastronomy and to use the creation of echoes for radiolocation. Although he received no scientific award for his discovery, Jansky's name is primarily honoured by its use as the unit of stellar radio-emission strength.[br]Bibliography1935, "Directional studies of atmospherics at high frequencies", Proceedings of the Institute of Radio Engineers 23:1,158.1935, "A note on the sources of stellar interference", Proceedings of the Institute of RadioEngineers.1937, "Minimum noise levels obtained on short-wave radio receiving systems", Proceedings of the Institute of Radio Engineers 25:1,517.1941, "Measurements of the delay and direction of arrival of echoes from nearby short-wave transmitters", Proceedings of the Institute of Radio Engineers 29:322.Further ReadingP.C.Mahon, 1975, BellLabs, Mission Communication.

47 Kennelly, Arthur Edwin
[br]b. 17 December 1871 Colaba, Bombay, Indiad. 18 June 1939 Boston, Massachusetts, USA[br]Anglo-American electrical engineer who predicted the ionosphere and developed mathematical analysis for electronic circuits.[br]As a young man, Kennelly worked as office boy for a London engineering society, as an electrician and on a cable-laying ship. In 1887 he went to work for Thomas Edison at West Orange, New Jersey, USA, becoming his chief assistant. In 1894, with Edwin J.Houston, he formed the Philadelphia company of Houston and Kennelly, but eight years later he took up the Chair of Electrical Engineering at Harvard, a post he held until his retirement in 1930. In 1902 he noticed that the radio signals received by Marconi in Nova Scotia from the transmitter in England were stronger than predicted and postulated a reflecting ionized layer in the upper atmosphere. Almost simultaneously the same prediction was made in England by Heaviside, so the layer became known as the Kennelly-Heaviside layer. Throughout most of his working life Kennelly was concerned with the application of mathematical techniques, particularly the use of complex theory, to the analysis of electrical circuits. With others he also contributed to an understanding of the high-frequency skin-effect in conductors.[br]Principal Honours and DistinctionsPresident, American Institute of Electrical Engineers 1898–1900.

After postgraduate study in Vienna, he returned to Chicago and was appointed Professor of Surgery at Northwestern University. He pioneered surgical techniques in the pneumothoracic, biliary and gastrointestinal systems with the invention of the Murphy "button" for intestinal anastomosis. He also originated a procedure for the replacement of infected joints utilizing a living graft of fascial tissue. He was described by W.J. Mayo as "the surgical genius of our century".[br]Principal Honours and DistinctionsKnight Commander of the Order of St Gregory 1910. Hon. Fellow, Royal College of Surgeons 1913.

49 Singer, Isaac Merritt
[br]b. 27 October 1811 Pittstown, New York, USAd. 23 July 1875 Torquay, Devonshire, England[br]American inventor of a sewing machine, and pioneer of mass production.[br]The son of a millwright, Singer was employed as an unskilled labourer at the age of 12, but later gained wide experience as a travelling machinist. He also found employment as an actor. On 16 May 1839, while living at Lockport, Illinois, he obtained his first patent for a rock-drilling machine, but he soon squandered the money he made. Then in 1849, while at Pittsburgh, he secured a patent for a wood-and metal-carving machine that he had begun five years previously; however, a boiler explosion in the factory destroyed his machine and left him penniless.Near the end of 1850 Singer was engaged to redesign the Lerow \& Blodgett sewing machine at the Boston shop of Orson C.Phelps, where the machine was being repaired. He built an improved version in eleven days that was sufficiently different for him to patent on 12 August 1851. He formed a partnership with Phelps and G.B. Zieber and they began to market the invention. Singer soon purchased Phelps's interest, although Phelps continued to manufacture the machines. Then Edward Clark acquired a one-third interest and with Singer bought out Zieber. These two, with dark's flair for promotion and marketing, began to create a company which eventually would become the largest manufacturer of sewing machines exported worldwide, with subsidiary factories in England.However, first Singer had to defend his patent, which was challenged by an earlier Boston inventor, Elias Howe. Although after a long lawsuit Singer had to pay royalties, it was the Singer machine which eventually captured the market because it could do continuous stitching. In 1856 the Great Sewing Machine Combination, the first important pooling arrangement in American history, was formed to share the various patents so that machines could be built without infringements and manufacture could be expanded without fear of litigation. Singer contributed his monopoly on the needle-bar cam with his 1851 patent. He secured twenty additional patents, so that his original straight-needle vertical design for lock-stitching eventually included such refinements as a continuous wheel-feed, yielding presser-foot, and improved cam for moving the needle-bar. A new model, introduced in 1856, was the first to be intended solely for use in the home.Initially Phelps made all the machines for Singer. Then a works was established in New York where the parts were assembled by skilled workers through filing and fitting. Each machine was therefore a "one-off" but Singer machines were always advertised as the best on the market and sold at correspondingly high prices. Gradually, more specialized machine tools were acquired, but it was not until long after Singer had retired to Europe in 1863 that Clark made the change to mass production. Sales of machines numbered 810 in 1853 and 21,000 ten years later.[br]Bibliography12 August 1851, US patent no. 8,294 (sewing machine)Further ReadingBiographies and obituaries have appeared in Appleton's Cyclopedia of America, Vol. V; Dictionary of American Biography, Vol XVII; New York Times 25 July 1875; Scientific American (1875) 33; and National Cyclopaedia of American Biography.D.A.Hounshell, 1984, From the American System to Mass Production 1800–1932.

[br]b. 27 June 1901 Canton, South Dakota, USAd. 20 May 1982 Bethesda, Maryland, USA[br]American physicist and geophysicist who developed radio exploration of the ionosphere and made contributions to seismology and atomic physics.[br]After BS and AM degrees from the University of Minnesota, Tuve gained a PhD in physics from Johns Hopkins University in 1926. He then joined the Department of Terrestrial Magnetism at the Carnegie Institute, Washington, DC, where with Breit he established by experiment the existence and characteristics of the ionosphere. He also studied gamma and beta rays, artificial radioactivity and atomic transmutation, verified the existence of the neutron and measured nuclear binding forces. During the Second World War he performed military research, producing a proximity fuse for use against the VI flying bomb. He returned to Carnegie in 1946 as Director of the Department of Terrestrial Magnetism, where he remained until 1966, making many contributions to the study of the earth and space.[br]Principal Honours and DistinctionsAmerican Association for the Advancement of Science Prize for atomic and nuclear research 1931.
