James Chadwick was born on October 20th, 1891 and started his journey in the science world in 1908, Experiments done in Europe by Frederic and Irene Joliot Curie had caught his attention, leading him toward the study of radiology. After completing High School, Chadwick attended Manchester University in 1908, and later graduated from the Honours School of Physics in 1911 and spent the next two years under Professor Rutherford whom he helped in the creation of ‘proton-electron …show more content…
pair.’
Chadwick played a vital role in the atomic theory, as he discovered the Neutron. Neutrons are located in the center of an atom, in the nucleus along with the protons. They do not have a positive or negative charge, but contribute to the atomic weight with the same effect as a proton. In 1930, it was discovered that Beryllium, when bombarded by alpha particles, emitted a very energetic stream of radiation. In 1935, he was awarded the Nobel Prize for his discovery.
Chadwick's reputation manifested his involvement with the atomic bomb and the single-mindedness he brought to the early thinking and feasibility work in Britain, and to the subsequent development of the weapon in the US.
Chadwick, among the first to see the potential for a weapon and to realize that Nazi Germany might be making it, threw himself into the task and ended up in effect in charge on the British side. As the pressures of war became greater, the British realized that even with their advances, they did not have the practical resources to develop a working atomic bomb. In 1943 Britain and the United States signed the Quebec Agreement, which created a partnership between the two countries for developing an atomic bomb. Chadwick became the leader of the British contingent involved in the Manhattan Project in the United States. Although he was shy and used to the isolation of the laboratory, Chadwick became known for his tireless efforts. Chadwick's postwar involvement with nuclear energy was not limited to weapons. He also was interested in medical applications of radioactive materials, and he worked to develop ways of regulating radioactive substances. Chadwick and his wife, Aileen Stewart-Brown, whom he married in 1925, had twin daughters. Chadwick was shy and serious and had an exacting sense of discipline and a tireless attention to detail. When he was at the Cavendish laboratory, all papers that went out for publication passed under his critical
gaze.
