21 Kettering, Charles Franklin
SUBJECT AREA: Automotive engineering, Electricity, Electronics and information technology, Metallurgy, Steam and internal combustion engines[br]b. 29 August 1876 near Londonsville, Ohio, USAd. 25 November 1958 Dayton, Ohio, USA[br]American engineer and inventor.[br]Kettering gained degrees in mechanical and electrical engineering from Ohio State University. He was employed by the National Construction Register (NCR) of Dayton, Ohio, where he devised an electric motor for use in cash registers. He became Head of the Inventions Department of that company but left in 1909 to form, with the former Works Manager of NCR, Edward A. Deeds, the Dayton Engineering Laboratories (later called Delco), to develop improved lighting and ignition systems for automobiles. In the first two years of the new company he produced not only these but also the first self-starter, both of which were fitted to the Cadillac, America's leading luxury car. In 1914 he founded Dayton Metal Products and the Dayton Wright Airplane Company. Two years later Delco was bought by General Motors. In 1925 the independent research facilities of Delco were moved to Detroit and merged with General Motors' laboratories to form General Motors Research Corporation, of which Kettering was President and General Manager. (He had been Vice-President of General Motors since 1920.) In that position he headed investigations into methods of achieving maximum engine performance as well as into the nature of friction and combustion. Many other developments in the automobile field were made under his leadership, such as engine coolers, variable-speed transmissions, balancing machines, the two-way shock absorber, high-octane fuel, leaded petrol or gasoline, fast-drying lacquers, crank-case ventilators, chrome plating, and the high-compression automobile engine. Among his other activities were the establishment of the Charles Franklin Kettering Foundation for the Study of Chlorophyll and Photosynthesis at Antioch College, and the founding of the Sloan- Kettering Institute for Cancer Research in New York City. He sponsored the Fever Therapy Research Project at Miami Valley Hospital at Dayton, which developed the hypertherm, or artificial fever machine, for use in the treatment of disease. He resigned from General Motors in 1947.IMcNBiographical history of technology > Kettering, Charles Franklin

26 Mavor, Henry Alexander
[br]b. 1858 Stranraer, Scotlandd. 16 July 1915 Mauchline, Ayrshire, Scotland[br]Scottish engineer who pioneered the use of electricity for lighting, power and the propulsion of ships.[br]Mavor came from a distinguished Scottish family with connections in medicine, industry and the arts. On completion of his education at Glasgow University, he joined R.J.Crompton \& Co.; then in 1883, along with William C.Muir, he established the Glasgow firm which later became well known as Mavor and Coulson. It pioneered the supply of electricity to public undertakings and equipped the first two generating stations in Scotland. Mavor and his fellow directors appreciated the potential demand by industry in Glasgow for electricity. Two industries were especially well served; first, the coal-mines, where electric lighting and power transformed efficiency and safety beyond recognition; and second, marine engineering. Here Mavor recognized the importance of the variable-speed motor in working with marine propellers which have a tighter range of efficient working speeds. In 1911 he built a 50 ft (15 m) motor launch, appropriately named Electric Arc, at Dumbarton and fitted it with an alternating-current motor driven by a petrol engine and dynamo. Within two years British shipyards were building electrically powered ships, and by the beginning of the First World War the United States Navy had a 20,000-ton collier with this new form of propulsion.[br]Principal Honours and DistinctionsVice-President, Institution of Engineers and Shipbuilders in Scotland 1894–6.BibliographyMavor published several papers on electric power supply, distribution and the use of electricity for marine purposes in the Transactions of the Institution of Engineers and Shipbuilders in Scotland between the years 1890 and 1912.Further ReadingMavor and Coulson Ltd, 1911, Electric Propulsion of Ships, Glasgow.FMW
