James Chadwick was born in Cheshire, England, on 20th October, 1891, the son of John Joseph Chadwick and Anne Mary Knowles. He attended Manchester High School prior to entering Manchester University in 1908; he graduated from the Honours School of Physics in 1911 and spent the next two years under Professor (later Lord) Rutherford in the Physical Laboratory in Manchester, where he worked on various radioactivity problems, gaining his M.Sc. degree in 1913 That same year he was awarded the 1851 Exhibition Scholarship and proceeded to Berlin to work in the Physikalisch Technische Reichsanstalt at Charlottenburg under Professor H. Geiger. During World War I, he was interned in the Zivilgefangenenlager, Ruhleben. After the war, in 1919, he returned to England to accept the Wollaston Studentship at Gonville and Caius College, Cambridge , and to resume work under Rutherford, who in the meantime had moved to the Cavendish Laboratory, Cambridge

Chadwick, Sir James Sir James Chadwick Corbis-Bettmann (b. Oct. 20, 1891, Manchester, Eng.d. July 24, 1974, Cambridge, Cambridgeshire), English physicist who received the Nobel Prize for Physics in 1935 for the discovery of the neutron Educated at the universities of Manchester and Cambridge, Chadwick also studied under Hans Geiger at the Technische Hochschule, Berlin. From 1923 he worked with Ernest Rutherford in the Cavendish Laboratory, Cambridge, where they studied the transmutation of elements by bombarding them with alpha particles and investigated the nature of the atomic nucleus, identifying the proton, the nucleus of the hydrogen atom, as a constituent of the nuclei of other atoms. In 1932 Chadwick observed that beryllium, when exposed to bombardment by alpha particles, released an unknown radiation that in turn ejected protons from the nuclei of various substances. Chadwick interpreted this radiation as being composed of particles of mass approximately equal to that of the proton, but without electrical chargeneutrons. This discovery provided a new tool for inducing atomic disintegration, since neutrons, being electrically uncharged, could penetrate undeflected into the atomic nucleus. Chadwick was knighted in 1945.

subsequent history may have been quite different had the neutron been discovered even a year later than it was. Had the ensuing breakthroughs in nuclear physics, such as the creation of the first chain reaction, been likewise delayed even a year, the A-bomb might have been ready for use, not in August 1945, but in August 1946, too late to have been used against Japan. Without the memory of the horror of Hiroshima to deter war between the Soviets and the West, such a war probably would have occurred; one way or the other, such a war would have made the world a very different place than it is now. In 1935 Chadwick left Cambridge for the University of Liverpool, where he used his Nobel Prize money to buy a cycletron, and, after the start of WWII, he explored the possibility of building an A- bomb; his motivation was a concern that the Allies would be naked if Heisenberg etc. could build a bomb for Hitler.

one of the fathers of the A-bomb, in 1932. This award is one of the most significant imaginable 20th Century historical objects. It is not only of museum quality, but is of the quality that museums are built around, and is of a magnitude that could warrant the creation of a museum with this as the collection's central object. Chadwick's discovery is generally considered one of the greatest discoveries ever, and was listed by Time as one of the 100 milestones of the 20th Century. Normally, Nobel medals and diplomas of this magnitude are considered national treasures and remain in the hands of the recipient's family or are displayed prominently in a national museum. A good example of the usual treatment accorded to Nobel Prizes of this magnitude is the story of the George Marshall 1953 Nobel Peace Prize at the George C. Marshall Museum on the campus of the Virginia Military Institute. In this case, the Marshall family lent this Nobel Prize to the

He attended Manchester University Honours School of Physics and graduated in 1911. While working on his Master's degree, Chadwick took a job in the Physical laboratory in Manchester where he studied with Professor Ernest Rutherford. In 1913, Chadwick received his Master's degree and received the 1851 Exhibition Scholarship, allowing him to continue his research and move to Berlin to work with Professor Hans Geiger. He later returned to England and was granted the Wollaston Scholarship at Gonville and Cains College in Cambridge, where he resumed working on atomic studies with Rutherford. In 1932, Chadwick proved the existence of neutrons. This momentous discovery contributed to the successful controlled fissioning of Uranium-235, and eventually to the development of the atomic bomb. For his discovery, Chadwick received the 1932 Hughes Medal of the Royal Society. In 1935, Chadwick was awarded the Nobel Prize in Physics. King George VI knighted him Sir James in 1945. From 1943 to 1946, Chadwick was the Head of the British Mission collaborating with the Manhattan Project in Los Alamos. Chadwick became a leading advocate for developing the atomic bomb in Britain and was the predominant scientist associated with the effort.

Cambridge Physics Chadwick Sir James Chadwick: 1893 - 1981 Awarded the Nobel Prize in Physics in 1935 for the discovery of the Neutron. This discovery was named as one of the greatest scientific achievements of all time and considered by Time Magazine as one of the most important milestones of the 20th century. Over the next several years, teams of researchers in several countries bombarded every known element with neutrons and recorded hundreds of new radioactive isotopes. Chadwick was key in connecting British scientists with the Manhattan Project. He was close with Manhattan Project's leader General Groves, and worked with British counterparts to determine that Americans had oversetimated the amount of U235 needed to achieve a chain reaction (critical mass). Chadwick and many of Britain's other leading physicists joined to form 'the Maud Committee', and produced a report saying that a nuclear bomb could be ready by 1943. He helped draft agreements to provide uranium for the Manhattan Project, maintained the morale of British scientists during their time in America, and was responsible for British observers being present at the bombing of Nagasaki.

Sir James Chadwick Biography Sir James Chadwick was an englishman born on October 20, 1891, in Manchester, England. Strangely, while enrolling in the University of Manchester, Chadwick who intended to major in mathematics acidentally found himself in the physics line. Too shy to admit his mistake, he stayed in line. Good thing he made that mistake. While working with Ernest Rutherford, Chadwick heard him speculating on the exitence of a particle with no charge which sparked his interest. Sir James performed experiments where he bombarded certain light elements with alpha particles leading to the discovery of a new type of particle, the neutron. For this, he won the Nobel Prize for physics in 1935. James Chadwick would die on July 14, 1974. Did you know? that James Chadwick was knighted in 1945. Want to know more about James Chadwick?

Sir James Chadwick He was awarded the 1935 Nobel Prize for Fizzix for his discovery of the neutron. Born in Manchester in 1891, he attended the Manchester Grammar School and entered the University of Manchester in 1908. He graduated with Honours from the Fizzix Department in 1911. He continued to work there with Rutherford from 1911 to 13, when he recieved his MSc. He worked with Geiger at the Physikalische-Technische Reichsanstalt in Berlin from then on, and published a book called "Radiation from Radioactive Substances" jointly with Ellis and Geiger in 1930. In 1919, he returned to England to work at Cavendish, and eventually became the director. His research there was based on the split- ting of atoms by bombardment using alpha particles. In 1930 Bothe and the Joliot-Curies found that when beryllium were bombarded with alpha particles, some sort of radiation occured which caused paraffin oil to eject protons, however, they offered no satisfactory explaination. Chadwick stepped in and suggested that a netural particle, with approximately the mass of the proton, was responsible for this strange behaviour. Enegry measurments confirmed his theory, and he was able to calcaulate the mass of Neutron. At the time it was already known from Thomson and Rutherford's results that an atom consisted of a nucleus surrounded by a cloud of electrons. Proton was the only thing that made up the nucleus, which was positively charged. However, when a thin foil of Be is bombarded with Alpha radiation, (which consisted of a Helium nucleus), a mysterious particle is ejected. This discovery subsequently lead to the discovery of the nuclear fission process. Chadwick's knowledge of British and German physics and had helped the development of the Uranium fission bomb during the second world war, a project which he regretted for getting himself involved. He eventually retired in 1958 and lived in North Wales for the rest of his life.
