21 Oberth, Hermann Julius
SUBJECT AREA: Aerospace[br]b. 25 June 1894 Nagyszeben, Transylvania (now Sibiu, Romania)d. 29 December 1989 Nuremberg, Germany[br]Austro-Hungarian lecturer who is usually regarded, with Robert Goddard, as one of the "fathers" of modern astronautics.[br]The son of a physician, Oberth originally studied medicine in Munich, but his education was interrupted by the First World War and service in the Austro-Hungarian Army. Wounded, he passed the time by studying astronautics. He apparently simulated weightlessness and worked out the design for a long-range liquid-propelled rocket, but his ideas were rejected by the War Office; after the war he submitted them as a dissertation for a PhD at Heidelberg University, but this was also rejected. Consequently, in 1923, whilst still an unknown mathematics teacher, he published his ideas at his own expense in the book The Rocket into Interplanetary Space. These included a description of how rockets could achieve a sufficient velocity to escape the gravitational field of the earth. As a result he gained international prestige almost overnight and learned of the work of Robert Goddard and Konstantin Tsiolkovsky. After correspondence with the Goddard and Tsiolkovsky, Oberth published a further work in 1929, The Road to Space Travel, in which he acknowledged the priority of Goddard's and Tsiolkovski's calculations relating to space travel; he went on to anticipate by more than thirty years the development of electric and ionic propulsion and to propose the use of giant mirrors to control the weather. For this he was awarded the annual Hirsch Prize of 10,000 francs. From 1925 to 1938 he taught at a college in Mediasch, Transylvania, where he carried out experiments with petroleum and liquid-air rockets. He then obtained a lecturing post at Vienna Technical University, moving two years later to Dresden University and becoming a German citizen. In 1941 he became assistant to the German rocket engineer Werner von Braun at the rocket development centre at Peenemünde, and in 1943 he began work on solid propellants. After the Second World War he spent a year in Switzerland as a consultant, then in 1950 he moved to Italy to develop solid-propellant anti-aircraft rockets for the Italian Navy. Five years later he moved to the USA to carry out advanced rocket research for the US Army at Huntsville, Alabama, and in 1958 he retired to Feucht, near Nuremberg, Germany, where he wrote his autobiography.[br]Principal Honours and DistinctionsFrench Astronautical Society REP-Hirsch Prize 1929.

22 Röntgen, Wilhelm Conrad
[br]b. 27 March 1845 Lennep, Prussia (now Remscheid, Germany)d. 10 February 1923 Munich, Germany[br]German physicist who discovered X-rays.[br]Expelled from school and so unable to attend university, Röntgen studied engineering at Zurich Polytechnic. After graduation he obtained a post as assistant to the distinguished German physicist Kundt and eventually secured an appointment at the University of Würzburg in Bavaria. He was successively Professor of Physics at the universities of Strasbourg (1876), Giessen (1879), Würzburg (1888) and Munich (1900–20), but he died in abject poverty. At various times he studied piezo-electricity; heat absorption by and the specific heat of gases; heat conduction in crystals; elasticity; and the capillary action of fluids. In 1895, whilst experimenting with the Crookes tube, a partially evacuated tube invented some seven years earlier, he observed that when a high voltage was applied across the tube, a nearby piece of barium platinocyanide produced light. He theorized that when the so-called cathode rays produced by the tube (electrons, as we now know) struck the glass wall, some unknown radiation occurred that was able to penetrate light materials and affect photographic plates. These he called X-rays (they also became known as Röntgen rays), but he believed (erroneously) that they bore no relation to light rays. For this important discovery he was awarded the Nobel Prize for Physics, but, sadly, he died in abject poverty during the hyperinflation of the 1920s.[br]Principal Honours and DistinctionsFirst Nobel Prize for Physics 1901.Bibliography1895, "A new kind of radiation", Meeting of the Würzburg Physical-Medical Society (December) (reported Röntgen's discovery of X-rays).Further ReadingO.Glasser, 1945, Dr. W.C.Röntgen (biography).KFBiographical history of technology > Röntgen, Wilhelm Conrad

23 Wheatstone, Sir Charles
SUBJECT AREA: Telecommunications[br]b. 1802 near Gloucester, Englandd. 19 October 1875 Paris, France[br]English physicist, pioneer of electric telegraphy.[br]Wheatstone's family moved to London when he was 4 years old. He was educated at various schools in London and excelled in physics and mathematics. He qualified for a French prize but forfeited it because he was too shy to recite a speech in French at the prize-giving.An uncle, also called Charles Wheatstone, has a musical instrument manufacturing business where young Charles went to work. He was fascinated by the science of music, but did not enjoy business life. After the uncle's death, Charles and his brother William took over the business. Charles developed and patented the concertina, which the firm assembled from parts made by "outworkers". He devoted much of his time to studying the physics of sound and mechanism of sound transmission through solids. He sent speech and music over considerable distances through solid rods and stretched wires, and envisaged communication at a distance. He concluded, however, that electrical methods were more promising.In 1834 Wheatstone was appointed Professor of Experimental Philosophy—a part-time posi-tion—in the new King's College, London, which gave him some research facilities. He conducted experiments with a telegraph system using several miles of wire in the college corridors. Jointly with William Fothergill Cooke, in 1837 he obtained the first patent for a practical electric telegraph, and much of the remainder of his life was devoted to its improvement. In 1843 he gave a paper to the Royal Society surveying the state of electrical measurements and drew attention to a bridge circuit known ever since as the "Wheatstone bridge", although he clearly attributed it to S.H.Christie. Wheatstone devised the "ABC" telegraph, for use on private lines by anyone who could read, and a high-speed automatic telegraph which was adopted by the Post Office and used for many years. He also worked on the French and Belgian telegraph systems; he died when taken ill on a business visit to Paris.[br]Further ReadingB.Bowers, 1975, Sir Charles Wheatstone FRS, London: HMSO.BBBiographical history of technology > Wheatstone, Sir Charles

33 Boot, Henry Albert Howard
[br]b. 29 July 1917 Birmingham, Englandd. 8 February 1983 Cambridge, England[br]English physicist who, with John Randall, invented the cavity magnetron used in radar systems.[br]After secondary education at King Edward School, Birmingham, Boot studied physics at Birmingham University, obtaining his BSc in 1938 and PhD in 1941. With the outbreak of the Second World War, he became involved with Randall and others in the development of a source of microwave power suitable for use in radar transmitters. Following unsuccessful attempts to use klystrons, they turned to investigation of the magnetron, and by adding cavity resonators they obtained useful power on 21 February 1940 at a wavelength of 9.8 cm. By May a cavity magnetron radar system had been constructed at TRE, Swanage, and in September submarine periscopes were detected at a range of 7 miles (11 km).In 1943 the physics department at Birmingham resumed its research in atomic physics and Boot moved to BTH at Rugby to continue development of magnetrons, but in 1945 he returned to Birmingham as Nuffield Research Fellow and helped construct the cyclotron there. Three years later he took up a post as a Principal Scientific Officer (PSO) at the Services Electronic Research Laboratories at Baldock, Hertfordshire, becoming a Senior PSO in 1954. He remained there until his retirement in 1977, variously carrying out research on microwaves, magnetrons, plasma physics and lasers.[br]Principal Honours and DistinctionsRoyal Society of Arts Thomas Gray Memorial Prize 1943.

34 Booth, Henry
[br]b. 4 April 1789 Liverpool, Englandd. 28 March 1869 Liverpool, England[br]English railway administrator and inventor.[br]Booth followed his father as a Liverpool corn merchant but had great mechanical aptitude. In 1824 he joined the committee for the proposed Liverpool \& Manchester Railway (L \& MR) and after the company obtained its Act of Parliament in 1826 he was appointed Treasurer.In 1829 the L \& MR announced a prize competition, the Rainhill Trials, for an improved steam locomotive: Booth, realizing that the power of a locomotive depended largely upon its capacity to raise steam, had the idea that this could be maximized by passing burning gases from the fire through the boiler in many small tubes to increase the heating surface, rather than in one large one, as was then the practice. He was apparently unaware of work on this type of boiler even then being done by Marc Seguin, and the 1791 American patent by John Stevens. Booth discussed his idea with George Stephenson, and a boiler of this type was incorporated into the locomotive Rocket, which was built by Robert Stephenson and entered in the Trials by Booth and the two Stephensons in partnership. The boiler enabled Rocket to do all that was required in the trials, and far more: it became the prototype for all subsequent conventional locomotive boilers.After the L \& MR opened in 1830, Booth as Treasurer became in effect the general superintendent and was later General Manager. He invented screw couplings for use with sprung buffers. When the L \& MR was absorbed by the Grand Junction Railway in 1845 he became Secretary of the latter, and when, later the same year, that in turn amalgamated with the London \& Birmingham Railway (L \& BR) to form the London \& North Western Railway (L \& NWR), he became joint Secretary with Richard Creed from the L \& BR.Earlier, completion in 1838 of the railway from London to Liverpool had brought problems with regard to local times. Towns then kept their own time according to their longitude: Birmingham time, for instance, was 7¼ minutes later than London time. This caused difficulties in railway operation, so Booth prepared a petition to Parliament on behalf of the L \& MR that London time should be used throughout the country, and in 1847 the L \& NWR, with other principal railways and the Post Office, adopted Greenwich time. It was only in 1880, however, that the arrangement was made law by Act of Parliament.[br]Bibliography1835. British patent no. 6,814 (grease lubricants for axleboxes). 1836.

35 Clarke, Arthur Charles
[br]b. 16 December 1917 Minehead, Somerset, England[br]English writer of science fiction who correctly predicted the use of geo-stationary earth satellites for worldwide communications.[br]Whilst still at Huish's Grammar School, Taunton, Clarke became interested in both space science and science fiction. Unable to afford a scientific education at the time (he later obtained a BSc at King's College, London), he pursued both interests in his spare time while working in the Government Exchequer and Audit Department between 1936 and 1941. He was a founder member of the British Interplanetary Society, subsequently serving as its Chairman in 1946–7 and 1950–3. From 1941 to 1945 he served in the Royal Air Force, becoming a technical officer in the first GCA (Ground Controlled Approach) radar unit. There he began to produce the first of many science-fiction stories. In 1949–50 he was an assistant editor of Science Abstracts at the Institution of Electrical Engineers.As a result of his two interests, he realized during the Second World War that an artificial earth satellite in an equatorial orbital with a radius of 35,000 km (22,000 miles) would appear to be stationary, and that three such geo-stationary, or synchronous, satellites could be used for worldwide broadcast or communications. He described these ideas in a paper published in Wireless World in 1945. Initially there was little response, but within a few years the idea was taken up by the US National Aeronautics and Space Administration and in 1965 the first synchronous satellite, Early Bird, was launched into orbit.In the 1950s he moved to Ceylon (now Sri Lanka) to pursue an interest in underwater exploration, but he continued to write science fiction, being known in particular for his contribution to the making of the classic Stanley Kubrick science-fiction film 2001: A Space Odyssey, based on his book of the same title.[br]Principal Honours and DistinctionsClarke received many honours for both his scientific and science-fiction writings. For his satellite communication ideas his awards include the Franklin Institute Gold Medal 1963 and Honorary Fellowship of the American Institute of Aeronautics and Astronautics 1976. For his science-fiction writing he received the UNESCO Kalinga Prize (1961) and many others. In 1979 he became Chancellor of Moratuwa University in Sri Lanka and in 1980 Vikran Scrabhai Professor at the Physical Research Laboratory of the University of Ahmedabad.Bibliography1945.

36 Davy, Sir Humphry
[br]b. 17 December 1778 Penzance, Cornwall, Englandd. 29 May 1829 Geneva, Switzerland[br]English chemist, discoverer of the alkali and alkaline earth metals and the halogens, inventor of the miner's safety lamp.[br]Educated at the Latin School at Penzance and from 1792 at Truro Grammar School, Davy was apprenticed to a surgeon in Penzance. In 1797 he began to teach himself chemistry by reading, among other works, Lavoisier's elementary treatise on chemistry. In 1798 Dr Thomas Beddoes of Bristol engaged him as assistant in setting up his Pneumatic Institution to pioneer the medical application of the newly discovered gases, especially oxygen.In 1799 he discovered the anaesthetic properties of nitrous oxide, discovered not long before by the chemist Joseph Priestley. He also noted its intoxicating qualities, on account of which it was dubbed "laughing-gas". Two years later Count Rumford, founder of the Royal Institution in 1800, appointed Davy Assistant Lecturer, and the following year Professor. His lecturing ability soon began to attract large audiences, making science both popular and fashionable.Davy was stimulated by Volta's invention of the voltaic pile, or electric battery, to construct one for himself in 1800. That enabled him to embark on the researches into electrochemistry by which is chiefly known. In 1807 he tried decomposing caustic soda and caustic potash, hitherto regarded as elements, by electrolysis and obtained the metals sodium and potassium. He went on to discover the metals barium, strontium, calcium and magnesium by the same means. Next, he turned his attention to chlorine, which was then regarded as an oxide in accordance with Lavoisier's theory that oxygen was the essential component of acids; Davy failed to decompose it, however, even with the aid of electricity and concluded that it was an element, thus disproving Lavoisier's view of the nature of acids. In 1812 Davy published his Elements of Chemical Philosophy, in which he presented his chemical ideas without, however, committing himself to the atomic theory, recently advanced by John Dalton.In 1813 Davy engaged Faraday as Assistant, perhaps his greatest service to science. In April 1815 Davy was asked to assist in the development of a miner's lamp which could be safely used in a firedamp (methane) laden atmosphere. The "Davy lamp", which emerged in January 1816, had its flame completely surrounded by a fine wire mesh; George Stephenson's lamp, based on a similar principle, had been introduced into the Northumberland pits several months earlier, and a bitter controversy as to priority of invention ensued, but it was Davy who was awarded the prize for inventing a successful safety lamp.In 1824 Davy was the first to suggest the possibility of conferring cathodic protection to the copper bottoms of naval vessels by the use of sacrificial electrodes. Zinc and iron were found to be equally effective in inhibiting corrosion, although the scheme was later abandoned when it was found that ships protected in this way were rapidly fouled by weeds and barnacles.[br]Principal Honours and DistinctionsKnighted 1812.

37 Donald, Ian
SUBJECT AREA: Medical technology[br]b. 27 December 1910 Paisley, Scotlandd. 19 June 1987 Paglesham, Essex, England[br]Scottish obstetrician and gynaecologist, pioneer of the diagnostic use of ultrasound in medicine.[br]After he received his initial education in Scotland, Donald's family moved to South Africa, where he obtained a BA degree in Cape Town in 1930. After the death of his parents he returned to England, graduating in medicine in 1937. He served in the RAF from 1942 to 1946 and was awarded the MBE for bravery in rescuing air-crews. In 1954, following a fruitful period as Reader and Lecturer at St Thomas's Hospital and the Hammersmith Hospital, he was appointed Regius Professor of Midwifery in Glasgow. It was while at St Thomas's and Hammersmith that he evolved a demand-response respirator for infants. With the assistance of Tom Brown, an engineer, and the company Kelvin Hughes—which had earlier produced ultrasound equipment for detecting flaws in metal castings—he was able to originate, develop and improve the diagnostic use of ultra-sound in obstetrics and gynaecology. The use of this technique rapidly spread into other disciplines. Donald was fortunate in that the procedure proved to have no untoward influence on pregnancy; at the time, little was known of possible side effects.He was the proponent of other advances in the speciality, including laparoscopy, breast-feeding and the preservation of the membranes during labour. An ardent anti-abortionist, his authoritarian Scottish approach made Glasgow a world centre, with himself as a renowned and loved teacher. Despite undergoing three major cardiac interventions, his longevity did not surprise those who knew of his immense vitality.[br]Principal Honours and DistinctionsCBE 1973.

38 Essen, Louis
SUBJECT AREA: Horology[br]b. 6 September 1908 Nottingham, England[br]English physicist who produced the first practical caesium atomic clock, which was later used to define the second.[br]Louis Essen joined the National Physical Laboratory (NPL) at Teddington in 1927 after graduating from London University. He spent his whole working life at the NPL and retired in 1972; his research there was recognized by the award of a DSc in 1948. At NPL he joined a team working on the development of frequency standards using quartz crystals and he designed a very successful quartz oscillator, which became known as the "Essen ring". He was also involved with radio frequency oscillators. His expertise in these fields was to play a crucial role in the development of the caesium clock. The idea of an atomic clock had been proposed by I.I.Rabbi in 1945, and an instrument was constructed shortly afterwards at the National Bureau of Standards in the USA. However, this device never realized the full potential of the concept, and after seeing it on a visit to the USA Essen was convinced that a more successful instrument could be built at Teddington. Assisted by J.V.L.Parry, he commenced work in the spring of 1953 and by June 1955 the clock was working reliably, with an accuracy that was equivalent to one second in three hundred years. This was significantly more accurate than the astronomical observations that were used at that time to determine the second: in 1967 the second was redefined in terms of the value for the frequency of vibration of caesium atoms that had been obtained with this clock.[br]Principal Honours and DistinctionsFRS 1960.

39 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.

40 Stanhope, Charles, 3rd Earl
[br]b. 3 August 1753 London, Englandd. 15 December 1816 Chevening, Kent, England[br]English politician, scientist and inventor.[br]Stanhope's schooling at Eton was interrupted in 1764 when the family moved to Geneva; there, he soon showed a talent for scientific pursuits. In 1771 he contributed a paper on the pendulum to the Swedish Academy, which awarded him a prize for it. After his return to London in 1774, he threw himself into politics, earning himself not only a reputation for promoting the liberty of the individual, but also unpopularity for championing the French Revolution.Stanhope is best known for his inventions in printing. In 1800 he introduced the first successful iron press, known by his name. Its iron frame enabled a whole forme to be printed at one pull, thus speeding up production. The press retained the traditional screw but incorporated a system of levers which increased the pressure on the platen up to the moment of contact with the type, so that fine, sharp impressions were obtained and the work of the pressman was made easier. Stanhope's process for moulding and reproducing formes, known as stereotyping, became important when curved formes were required for cylinder presses. His invention of logotypes for casting type, however, proved a failure. Throughout his political activities, Stanhope devoted time and money to scientific and mechanical matters. Of these, the development of steamships is noteworthy. He took out patents in 1790 and 1807, and in 1796 he constructed the Kent for the Admiralty, but it was unsuccessful. In 1810, however, he claimed that a vessel 110 ft (33.5 m) long and 7 ft (2.1 m) in draught "outsailed the swiftest vessels in the Navy".[br]Further ReadingG.Stanhope, 1914, The Life of Charles, Third Earl Stanhope, London.H.Hart, 1966, Charles Earl Stanhope and the Oxford University Press, London: Printing Historical Society (a reprint of a paper, originally published in 1896, describing Stanhope's printing inventions; with copious quotations from Stanhope's own writings, together with an essay on the Stanhope press by James Moran).LRDBiographical history of technology > Stanhope, Charles, 3rd Earl
