84 Fermi, Enrico
[br]b. 29 September 1901 Rome, Italyd. 28 November 1954 Chicago, USA[br]Italian nuclear physicist.[br]Fermi was one of the most versatile of twentieth-century physicists, one of the few to excel in both theory and experiment. His greatest theoretical achievements lay in the field of statistics and his theory of beta decay. His statistics, parallel to but independent of Dirac, were the key to the modern theory of metals and the statistical modds of the atomic nucleus. On the experimental side, his most notable discoveries were artificial radioactivity produced by neutron bombardment and the realization of a controlled nuclear chain reaction, in the world's first nuclear reactor.Fermi received a conventional education with a chemical bias, but reached proficiency in mathematics and physics largely through his own reading. He studied at Pisa University, where he taught himself modern physics and then travelled to extend his knowledge, spending time with Max Born at Göttingen. On his return to Italy, he secured posts in Florence and, in 1927, in Rome, where he obtained the first Italian Chair in Theoretical Physics, a subject in which Italy had so far lagged behind. He helped to bring about a rebirth of physics in Italy and devoted himself to the application of statistics to his model of the atom. For this work, Fermi was awarded the Nobel Prize in Physics in 1938, but in December of that year, finding the Fascist regime uncongenial, he transferred to the USA and Columbia University. The news that nuclear fission had been achieved broke shortly before the Second World War erupted and it stimulated Fermi to consider this a way of generating secondary nuclear emission and the initiation of chain reactions. His experiments in this direction led first to the discovery of slow neutrons.Fermi's work assumed a more practical aspect when he was invited to join the Manhattan Project for the construction of the first atomic bomb. His small-scale work at Columbia became large-scale at Chicago University. This culminated on 2 December 1942 when the first controlled nuclear reaction took place at Stagg Field, Chicago, an historic event indeed. Later, Fermi spent most of the period from September 1944 to early 1945 at Los Alamos, New Mexico, taking part in the preparations for the first test explosion of the atomic bomb on 16 July 1945. President Truman invited Fermi to serve on his Committee to advise him on the use of the bomb. Then Chicago University established an Institute for Nuclear Studies and offered Fermi a professorship, which he took up early in 1946, spending the rest of his relatively short life there.[br]Principal Honours and DistinctionsNobel Prize for Physics 1938.Bibliography1962–5, Collected Papers, ed.

85 Guillaume, Charles-Edouard
[br]b. 15 February 1861 Fleurier, Switzerlandd. 13 June 1938 Sèvres, France[br]Swiss physicist who developed two alloys, "invar" and "elinvar", used for the temperature compensation of clocks and watches.[br]Guillaume came from a family of clock-and watchmakers. He was educated at the Gymnasium in Neuchâtel and at Zurich Polytechnic, from which he received his doctorate in 1883 for a thesis on electrolytic capacitors. In the same year he joined the International Bureau of Weights and Measures at Sèvres in France, where he was to spend the rest of his working life. He retired as Director in 1936. At the bureau he was involved in distributing the national standards of the metre to countries subscribing to the General Conference on Weights and Measures that had been held in 1889. This made him aware of the crucial effect of thermal expansion on the lengths of the standards and he was prompted to look for alternative materials that would be less costly than the platinum alloys which had been used. While studying nickel steels he made the surprising discovery that the thermal expansion of certain alloy compositions was less than that of the constituent metals. This led to the development of a steel containing about 36 per cent nickel that had a very low thermal coefficient of expansion. This alloy was subsequently named "invar", an abbreviation of invariable. It was well known that changes in temperature affected the timekeeping of clocks by altering the length of the pendulum, and various attempts had been made to overcome this defect, most notably the mercury-compensated pendulum of Graham and the gridiron pendulum of Harrison. However, an invar pendulum offered a simpler and more effective method of temperature compensation and was used almost exclusively for pendulum clocks of the highest precision.Changes in temperature can also affect the timekeeping of watches and chronometers, but this is due mainly to changes in the elasticity or stiffness of the balance spring rather than to changes in the size of the balance itself. To compensate for this effect Guillaume developed another more complex nickel alloy, "elinvar" (elasticity invariable), whose elasticity remained almost constant with changes in temperature. This had two practical consequences: the construction of watches could be simplified (by using monometallic balances) and more accurate chronometers could be made.[br]Principal Honours and DistinctionsNobel Prize for Physics 1920.

86 Haynes, Elwood
[br]b. 14 October 1857 Portland, Indiana, USAd. 13 April 1925 Kokomo, Indiana, USA[br]American inventor ofStellite cobalt-based alloys, early motor-car manufacturer and pioneer in stainless steels.[br]From his early years, Haynes was a practising Presbyterian and an active prohibitionist. He graduated in 1881 at Worcester, Massachusetts, and a spell of teaching in his home town was interrupted in 1884–5 while he attended the Johns Hopkins University in Baltimore. In 1886 he became permanently diverted by the discovery of natural gas in Portland. He was soon appointed Superintendent of the local gas undertaking, and then in 1890 he was hired by the Indiana Natural Gas \& Oil Company. While continuing his gas-company employment until 1901, Haynes conducted numerous metallurgical experiments. He also designed an automobile: this led to the establishment of the Haynes- Apperson Company at Kokomo as one of the earliest motor-car makers in North America. From 1905 the firm traded as the Haynes Automobile Company, and before its bankruptcy in 1924 it produced more than 50,000 cars. After 1905, Haynes found the first "Stellite" alloys of cobalt and chromium, and in 1910 he was publicizing the patented material. He then discovered the valuable hardening effect of tungsten, and in 1912 began applying the "improved" Stellite to cutting tools. Three years later, the Haynes Stellite Company was incorporated, with Haynes as President, to work the patents. It was largely from this source that Haynes became a millionaire in 1920. In April 1912, Haynes's attempt to patent the use of chromium with iron to render the product rustless was unsuccessful. However, he re-applied for a US patent on 12 March 1915 and, although this was initially rejected, he persevered and finally obtained recognition of his modified claim. The American Stainless Steel Company licensed the patents of Brearley and Haynes jointly in the USA until the 1930s.[br]Principal Honours and DistinctionsJohn Scott Medal 1919 (awarded for useful inventions).BibliographyHaynes was the author of more than twenty published papers and articles, among them: 1907, "Materials for automobiles", Proceedings of the American Society of MechanicalEngineers 29:1,597–606; 1910, "Alloys of nickel and cobalt with chromium", Journal of Industrial Engineeringand Chemistry 2:397–401; 1912–13, "Alloys of cobalt with chromium and other metals", Transactions of the American Institute of 'Mining Engineers 44:249–55;1919–20, "Stellite and stainless steel", Proceedings of the Engineering Society of WestPennsylvania 35:467–74.1 April 1919, US patent no. 1,299,404 (stainless steel).The four US patents worked by the Haynes Stellite Company were: 17 December 1907, patent no. 873,745.1 April 1913, patent no. 1,057,423.1 April 1913, patent no. 1,057, 828.17 August 1915, patent no. 1,150, 113.Further ReadingR.D.Gray, 1979, Alloys and Automobiles.

87 Percy, John
SUBJECT AREA: Metallurgy[br]b. 23 March 1817 Nottingham, Englandd. 19 June 1889 London, England[br]English metallurgist, first Professor of Metallurgy at the School of Mines, London.[br]After a private education, Percy went to Paris in 1834 to study medicine and to attend lectures on chemistry by Gay-Lussac and Thenard. After 1838 he studied medicine at Edinburgh, obtaining his MD in 1839. In that year he was appointed Professor of Chemistry at Queen's College, Birmingham, moving to Queen's Hospital at Birmingham in 1843. During his time at Birmingham, Percy became well known for his analysis of blast furnace slags, and was involved in the manufacture of optical glass. On 7 June 1851 Percy was appointed Metallurgical Professor and Teacher at the Museum of Practical Geology established in Jermyn Street, London, and opened in May 1851. In November of 1851, when the Museum became the Government (later Royal) School of Mines, Percy was appointed Lecturer in Metallurgy. In addition to his work at Jermyn Street, Percy lectured on metallurgy to the Advanced Class of Artillery at Woolwich from 1864 until his death, and from 1866 he was Superintendent of Ventilation at the Houses of Parliament. He served from 1861 to 1864 on the Special Committee on Iron set up to examine the performance of armour-plate in relation to its purity, composition and structure.Percy is best known for his metallurgical text books, published by John Murray. Volume I of Metallurgy, published in 1861, dealt with fuels, fireclays, copper, zinc and brass; Volume II, in 1864, dealt with iron and steel; a volume on lead appeared in 1870, followed by one on fuels and refractories in 1875, and the first volume on gold and silver in 1880. Further projected volumes on iron and steel, noble metals, and on copper, did not materialize. In 1879 Percy resigned from his School of Mines appointment in protest at the proposed move from Jermyn Street to South Kensington. The rapid growth of Percy's metallurgical collection, started in 1839, eventually forced him to move to a larger house. After his death, the collection was bought by the South Kensington (later Science) Museum. Now comprising 3,709 items, it provides a comprehensive if unselective record of nineteenth-century metallurgy, the most interesting specimens being those of the first sodium-reduced aluminium made in Britain and some of the first steel produced by Bessemer in Baxter House. Metallurgy for Percy was a technique of chemical extraction, and he has been criticized for basing his system of metallurgical instruction on this assumption. He stood strangely aloof from new processes of steel making such as that of Gilchrist and Thomas, and tended to neglect early developments in physical metallurgy, but he was the first in Britain to teach metallurgy as a discipline in its own right.[br]Principal Honours and DistinctionsFRS 1847.
