original basis of Szilard's conviction proved to be erroneous, but he held on to his idea tenaciously and it indeed came to fruition when nuclear fission, discovered in 1939, provided the missing key. Szilard was probably the first to suggest that neutron emis sion might accompany the fission reaction, that the number of
Feb 2, 2024 · He began his career in science in 1922 as a physicist at the Institute of Theoretical Physics at Berlin University and then moved to the medical college at St. Bartholomew’s Hospital in London. While there, he collaborated with T.A. Chalmers and was one of the first scientists to envisage the possibilities of nuclear fission and chain reactions.
Szilard coined and submitted the earliest known patent applications and the first publications for the concept of the electron microscope (1928), the cyclotron (1929), and contributed to the development of the linear accelerator (1928) in Germany.

The Collected Works of Leo Szilard. Edited by Bernard T. Feld and Gertrud Weiss Szilard — In this age of high specialization … it is extremely rare to find a person who encompassed and moulded such a wide range of subjects. But then Szilard would have been a remarkable personality at any period of time. His fields of interest were physics, biology, sociology and technology, and to each of these he brought in refreshingly new concepts and a highly original approach … By the time his ideas became accepted he had already forged ahead to take up a new attitude. Szilard himself illustrated this characteristic in a story which he liked to tell about himself. He served once on a jury in a murder case. When the first vote was taken, eleven jurors were in favour of convicting, but one — Szilard — was for acquittal. Since unanimity was required, the discussion was resumed and Szilard expounded his arguments. After some time another vote was taken; the result was again eleven to one, but this time eleven were for acquittal, and one for conviction: the odd vote was Szilard’s who had in the meantime changed his mind! … Szilard was primarily a theoretician but his engineering upbringing enabled him to devise experiments which always worked … His most important role was probably in relation to the release of nuclear energy. His own account makes fascinating reading.
From Nature 2 March 1973
Fifty, forty, even thirty years ago the pathway through school (and even college) mathematics was beset with the notice “Verboten.” … [A]nalysis was forbidden in geometry papers; calculus in doing analytical geometry or mechanics; while to mention a sine or cosine in the natural philosophy paper of a certain examining body would have been to pull the very whiskers of death … But, above all, there must be no departure from the order of Euclid, and to use a later proposition in the proof of an earlier was mortal sin.

May 14, 2018 · Nuclear Scientist Szilard started work in nuclear physics in 1934, at St. Bartholomew’s Hospital, London, England, and by the late 1930s, he had become part of the distinguished group of top atomic scientists. In London, Szilard started to experiment with Thomas A. Chalmers on radioactive elements.
This influential letter was in fact drafted by Szilard. In 1944 or early 1945, scientists at the Clinton Laboratories formed an organization called “The Association of Oak Ridge Scientists at Clinton Laboratories” for discussion of issues relating to atomic bombs and peaceful uses of atomic energy.

Slowly the idea began to take shape and in August of 1963, a meeting was held in Ravello, Italy, which resulted in three main proposals: Szilárd died in California in 1964. He was a scientist who was deeply concerned with world peace and with efforts to create what he called “a more livable world”.
