6 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.

7 Tuve, Merle Antony
[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.

[br]b. 6 September 1892 Bradford, Englandd. 21 April 1965 Edinburgh, Scotland[br]English physicist awarded the Nobel Prize for Physics for his discovery of the ionospheric layer, named after him, which is an efficient reflector of short radio waves, thereby making possible long-distance radio communication.[br]After early ambitions to become a professional cricketer, Appleton went to St John's College, Cambridge, where he studied under J.J.Thompson and Ernest Rutherford. His academic career interrupted by the First World War, he served as a captain in the Royal Engineers, carrying out investigations into the propagation and fading of radio signals. After the war he joined the Cavendish Laboratory, Cambridge, as a demonstrator in 1920, and in 1924 he moved to King's College, London, as Wheatstone Professor of Physics.In the following decade he contributed to developments in valve oscillators (in particular, the "squegging" oscillator, which formed the basis of the first hard-valve time-base) and gained international recognition for research into electromagnetic-wave propagation. His most important contribution was to confirm the existence of a conducting ionospheric layer in the upper atmosphere capable of reflecting radio waves, which had been predicted almost simultaneously by Heaviside and Kennelly in 1902. This he did by persuading the BBC in 1924 to vary the frequency of their Bournemouth transmitter, and he then measured the signal received at Cambridge. By comparing the direct and reflected rays and the daily variation he was able to deduce that the Kennelly- Heaviside (the so-called E-layer) was at a height of about 60 miles (97 km) above the earth and that there was a further layer (the Appleton or F-layer) at about 150 miles (240 km), the latter being an efficient reflector of the shorter radio waves that penetrated the lower layers. During the period 1927–32 and aided by Hartree, he established a magneto-ionic theory to explain the existence of the ionosphere. He was instrumental in obtaining agreement for international co-operation for ionospheric and other measurements in the form of the Second Polar Year (1932–3) and, much later, the International Geophysical Year (1957–8). For all this work, which made it possible to forecast the optimum frequencies for long-distance short-wave communication as a function of the location of transmitter and receiver and of the time of day and year, in 1947 he was awarded the Nobel Prize for Physics.He returned to Cambridge as Jacksonian Professor of Natural Philosophy in 1939, and with M.F. Barnett he investigated the possible use of radio waves for radio-location of aircraft. In 1939 he became Secretary of the Government Department of Scientific and Industrial Research, a post he held for ten years. During the Second World War he contributed to the development of both radar and the atomic bomb, and subsequently served on government committees concerned with the use of atomic energy (which led to the establishment of Harwell) and with scientific staff.[br]Principal Honours and DistinctionsKnighted (KCB 1941, GBE 1946).

SUBJECT AREA: Medical technology[br]b. 23 March 1905 Newton-le-Willows, Lancashire, Englandd. 16 June 1984 Edinburgh, Scotland[br]English physicist and biophysicist, primarily known for the development, with Boot of the cavity magnetron.[br]Following secondary education at Ashton-inMakerfield Grammar School, Randall entered Manchester University to read physics, gaining a first class BSc in 1925 and his MSc in 1926. From 1926 to 1937 he was a research physicist at the General Electric Company (GEC) laboratories, where he worked on luminescent powders, following which he became Warren Research Fellow of the Royal Society at Birmingham University, studying electronic processes in luminescent solids. With the outbreak of the Second World War he became an honorary member of the university staff and transferred to a group working on the development of centrimetric radar. With Boot he was responsible for the development of the cavity magnetron, which had a major impact on the development of radar.When Birmingham resumed its atomic research programme in 1943, Randall became a temporary lecturer at the Cavendish Laboratory in Cambridge. The following year he was appointed Professor of Natural Philosophy at the University of St Andrews, but in 1946 he moved again to the Wheatstone Chair of Physics at King's College, London. There his developing interest in biophysical research led to the setting up of a multi-disciplinary group in 1951 to study connective tissues and other biological components, and in 1950– 5 he was joint Editor of Progress in Biophysics. From 1961 until his retirement in 1970 he was Professor of Biophysics at King's College and for most of that time he was also Chairman of the School of Biological Sciences. In addition, for many years he was honorary Director of the Medical Research Council Biophysics Research Unit.After he retired he returned to Edinburgh and continued to study biological problems in the university zoology laboratory.[br]Principal Honours and DistinctionsKnighted 1962.
