6 Finsen, Neils Ryberg
SUBJECT AREA: Medical technology[br]b. 15 December 1860 Thorshavn, Faeroe Islandsd. 24 September 1904 Copenhagen, Denmark[br]Icelandic physician, investigator and pioneer of actinotherapy.[br]Following his early education in Reykjavik, Finsen moved to Copenhagen and obtained his medical degree in 1891. Appointed as a demonstrator in anatomy at the University of Copenhagen, he soon abandoned a career in academic medicine, preferring the sunlit environment of outdoor life. He was soon studying the nature of light-induced inflammation and proceeded to identify the radiation in the blue-violet and ultraviolet (actinic) parts of the solar spectrum as being particularly responsible. By 1893 he had discovered the beneficial effect of red light on the lesions of smallpox and in 1894 he put forward his conclusion that light possessed a direct therapeutic quality. In 1895 he amplified this work with the treatment of lupus vulgaris (tuberculosis of the skin) using a carbon-arc source suitably filtered to expose the tissues to high concentrations of ultraviolet rays. Extensions of this form of therapy were applied in a number of other conditions until superseded by the development of serology, chemotherapy and antibiotic drugs.In his final years, afflicted with a cardiac condition possibly related to the endemic hydatid disease of Iceland, he carried out an important self-study on salt and water metabolism, laying the foundations for the therapeutic concept of low fluid and low salt intake therapy.[br]Principal Honours and DistinctionsNobel Prize for Medicine or Physiology 1903 (the first such award).Bibliography1894.

7 Chapelon, André
[br]b. 26 October 1892 Saint-Paul-en-Cornillon, Loire, Franced. 29 June 1978 Paris, France[br]French locomotive engineer who developed high-performance steam locomotives.[br]Chapelon's technical education at the Ecole Centrale des Arts et Manufactures, Paris, was interrupted by extended military service during the First World War. From experience of observing artillery from the basket of a captive balloon, he developed a method of artillery fire control which was more accurate than that in use and which was adopted by the French army.In 1925 he joined the motive-power and rolling-stock department of the Paris-Orléans Railway under Chief Mechanical Engineer Maurice Lacoin and was given the task of improving the performance of its main-line 4–6–2 locomotives, most of them compounds. He had already made an intensive study of steam locomotive design and in 1926 introduced his Kylchap exhaust system, based in part on the earlier work of the Finnish engineer Kyläla. Chapelon improved the entrainment of the hot gases in the smokebox by the exhaust steam and so minimized back pressure in the cylinders, increasing the power of a locomotive substantially. He also greatly increased the cross-sectional area of steam passages, used poppet valves instead of piston valves and increased superheating of steam. PO (Paris-Orléans) 4–6–2s rebuilt on these principles from 1929 onwards proved able to haul 800-ton trains, in place of the previous 500-ton trains, and to do so to accelerated schedules with reduced coal consumption. Commencing in 1932, some were converted, at the time of rebuilding, into 4–8–0s to increase adhesive weight for hauling heavy trains over the steeply graded Paris-Toulouse line.Chapelon's principles were quickly adopted on other French railways and elsewhere.H.N. Gresley was particularly influenced by them. After formation of the French National Railways (SNCF) in 1938, Chapelon produced in 1941 a prototype rebuilt PO 2–10–0 freight locomotive as a six-cylinder compound, with four low-pressure cylinders to maximize expansive use of steam and with all cylinders steam-jacketed to minimize heat loss by condensation and radiation. War conditions delayed extended testing until 1948–52. Meanwhile Chapelon had, by rebuilding, produced in 1946 a high-powered, three-cylinder, compound 4–8–4 intended as a stage in development of a proposed range of powerful and thermally efficient steam locomotives for the postwar SNCF: a high-speed 4–6–4 in this range was to run at sustained speeds of 125 mph (200 km/h). However, plans for improved steam locomotives were then overtaken in France by electriflcation and dieselization, though the performance of the 4–8–4, which produced 4,000 hp (3,000 kW) at the drawbar for the first time in Europe, prompted modification of electric locomotives, already on order, to increase their power.Chapelon retired from the SNCF in 1953, but continued to act as a consultant. His principles were incorporated into steam locomotives built in France for export to South America, and even after the energy crisis of 1973 he was consulted on projects to build improved, high-powered steam locomotives for countries with reserves of cheap coal. The eventual fall in oil prices brought these to an end.[br]Bibliography1938, La Locomotive à vapeur, Paris: J.B.Bailière (a comprehensive summary of contemporary knowledge of every function of the locomotive).Further ReadingH.C.B.Rogers, 1972, Chapelon, Genius of French Steam, Shepperton: Ian Allan.1986, "André Chapelon, locomotive engineer: a survey of his work", Transactions of the Newcomen Society 58 (a symposium on Chapelon's work).Obituary, 1978, Railway Engineer (September/October) (makes reference to the technical significance of Chapelon's work).PJGR -
8 Crookes, Sir William
SUBJECT AREA: Electricity[br]b. 17 June 1832 London, Englandd. 4 April 1919 London, England[br]English chemist and physicist who carried out studies of electrical discharges and cathode rays in rarefied gases, leading to the development of the cathode ray tube; discoverer of the element thallium and the principle of the Crookes radiometer.[br]Crookes entered the Royal College of Chemistry at the age of 15, and from 1850 to 1854 held the appointment of Assistant at the college. In 1854 he became Superintendent of the Meteorological Department at the Radcliffe Observatory in Oxford. He moved to a post at the College of Science in Chester the following year. Soon after this he inherited a large fortune and set up his own private laboratory in London. There he studied the nature of electrical discharges in gases at low pressure and discovered the dark space (later named after him) that surrounds the negative electrode, or cathode. He also established that the rays produced in the process (subsequently shown by J.J.Thompson to be a stream of electrons) not only travelled in straight lines, but were also capable of producing heat and/or light upon impact with suitable anode materials. Using a variety of new methods to investigate these "cathode" rays, he applied them to the spectral analysis of compounds of selenium and, as a result, in 1861 he discovered the element thallium, finally establishing its atomic weight in 1873. Following his discovery of thallium, he became involved in two main lines of research: the properties of rarified gases, and the investigation of the elements of the "rare earths". It was also during these experiments that he discovered the principle of the Crookes radiometer, a device in which light is converted into rotational motion and which used to be found frequently in the shop windows of English opticians. Also among the fruits of this work were the Crookes tubes and the development of spectacle lenses with differential ranges of radiational absorption. In the 1870s he became interested in spiritualism and acquired a reputation for his studies of psychic phenomena, but at the turn of the century he returned to traditional scientific investigations. In 1892 he wrote about the possibility of wireless telegraphy. His work in the field of radioactivity led to the invention of the spinthariscope, an early type of detector of alpha particles. In 1900 he undertook investigations into uranium which led to the study of scintillation, an important tool in the study of radioactivity.While the theoretical basis of his work has not stood the test of time, his material discoveries, observations and investigations of new facts formed a basis on which others such as J.J. Thomson were to develop subatomic theory. His later involvement in the investigation of spiritualism led to much criticism, but could be justified on the basis of a belief in the duty to investigate all phenomena.[br]Principal Honours and DistinctionsKnighted 1897.

9 Pierce, John Robinson
[br]b. 27 March 1910 Des Moines, Iowa, USA[br]American scientist and communications engineer said to be the "father" of communication satellites.[br]From his high-school days, Pierce showed an interest in science and in science fiction, writing under the pseudonym of J.J.Coupling. After gaining Bachelor's, Master's and PhD degrees at the California Institute of Technology (CalTech) in Pasadena in 1933, 1934 and 1936, respectively, Pierce joined the Bell Telephone Laboratories in New York City in 1936. There he worked on improvements to the travelling-wave tube, in which the passage of a beam of electrons through a helical transmission line at around 7 per cent of the speed of light was made to provide amplification at 860 MHz. He also devised a new form of electrostatically focused electron-multiplier which formed the basis of a sensitive detector of radiation. However, his main contribution to electronics at this time was the invention of the Pierce electron gun—a method of producing a high-density electron beam. In the Second World War he worked with McNally and Shepherd on the development of a low-voltage reflex klystron oscillator that was applied to military radar equipment.In 1952 he became Director of Electronic Research at the Bell Laboratories' establishment, Murray Hill, New Jersey. Within two years he had begun work on the possibility of round-the-world relay of signals by means of communication satellites, an idea anticipated in his early science-fiction writings (and by Arthur C. Clarke in 1945), and in 1955 he published a paper in which he examined various possibilities for communications satellites, including passive and active satellites in synchronous and non-synchronous orbits. In 1960 he used the National Aeronautics and Space Administration 30 m (98 1/2 ft) diameter, aluminium-coated Echo 1 balloon satellite to reflect telephone signals back to earth. The success of this led to the launching in 1962 of the first active relay satellite (Telstar), which weighed 170 lb (77 kg) and contained solar-powered rechargeable batteries, 1,000 transistors and a travelling-wave tube capable of amplifying the signal 10,000 times. With a maximum orbital height of 3,500 miles (5,600 km), this enabled a variety of signals, including full bandwidth television, to be relayed from the USA to large receiving dishes in Europe.From 1971 until his "retirement" in 1979, Pierce was Professor of Electrical Engineering at CalTech, after which he became Chief Technologist at the Jet Propulsion Laboratories, also in Pasadena, and Emeritus Professor of Engineering at Stanford University.[br]Principal Honours and DistinctionsInstitute of Electrical and Electronics Engineers Morris N.Liebmann Memorial Award 1947; Edison Medal 1963; Medal of Honour 1975.
