18 Szilard, Leo
SUBJECT AREA: Weapons and armour[br]b. 11 February 1898 Budapest, Hungaryd. 30 May 1964 La Jolla, California, USA[br]Hungarian (naturalized American in 1943) nuclear-and biophysicist.[br]The son of an engineer, Szilard, after service in the Austro-Hungarian army during the First World War, studied electrical engineering at the University of Berlin. Obtaining his doctorate there in 1922, he joined the faculty and concentrated his studies on thermodynamics. He later began to develop an interest in nuclear physics, and in 1933, shortly after Hitler came to power, Szilard emigrated to Britain because of his Jewish heritage.In 1934 he conceived the idea of a nuclear chain reaction through the breakdown of beryllium into helium and took out a British patent on it, but later realized that this process would not work. In 1937 he moved to the USA and continued his research at the University of Columbia, and the following year Hahn and Meitner discovered nuclear fission with uranium; this gave Szilard the breakthrough he needed. In 1939 he realized that a nuclear chain reaction could be produced through nuclear fission and that a weapon with many times the destructive power of the conventional high-explosive bomb could be produced. Only too aware of the progress being made by German nuclear scientists, he believed that it was essential that the USA should create an atomic bomb before Hitler. Consequently he drafted a letter to President Roosevelt that summer and, with two fellow Hungarian émigrés, persuaded Albert Einstein to sign it. The result was the setting up of the Uranium Committee.It was not, however, until December 1941 that active steps began to be taken to produce such a weapon and it was a further nine months before the project was properly co-ordinated under the umbrella of the Manhattan Project. In the meantime, Szilard moved to join Enrico Fermi at the University of Chicago and it was here, at the end of 1942, in a squash court under the football stadium, that they successfully developed the world's first self-sustaining nuclear reactor. Szilard, who became an American citizen in 1943, continued to work on the Manhattan Project. In 1945, however, when the Western Allies began to believe that only the atomic bomb could bring the war against Japan to an end, Szilard and a number of other Manhattan Project scientists objected that it would be immoral to use it against populated targets.Although he would continue to campaign against nuclear warfare for the rest of his life, Szilard now abandoned nuclear research. In 1946 he became Professor of Biophysics at the University of Chicago and devoted himself to experimental work on bacterial mutations and biochemical mechanisms, as well as theoretical research on ageing and memory.[br]Principal Honours and DistinctionsAtoms for Peace award 1959.Further ReadingKosta Tsipis, 1985, Understanding Nuclear Weapons, London: Wildwood House, pp. 16–19, 26, 28, 32 (a brief account of his work on the atomic bomb).A collection of his correspondence and memories was brought out by Spencer Weart and Gertrud W.Szilard in 1978.CM -
19 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.
