 * __Biography of James Chadwick__**
 * James Chadwick born in Cheshire, England, on October 20, 1891.
 * He was the son of John Joseph Chadwick and Anne Mary Knowles.
 * He attended Manchester High School prior to entering Manchester University in 1908.
 * He later graduated form the Honors School of Physics in 1911.
 * He then spent two years working in a Physical Laboratory in Manchester, where he worked on various radioactivity problems also gaining is Masters degree in 1913.
 * That same year he was awarded the 1851 Exhibition Scholarship to proceeded to Berlin to continue his work.
 * While in Berlin he worked with Hans Geiger at the Technical University of Berlin.
 * __Chadwicks Discovery__**
 * In 1932 James Chadwick made one of the greatest discovers for nuclear science.
 * James discovered the nuetron in the atom, he was able to do this due to the fact that it has no electrical charge. This turned out to be an extremely useful tool for bombarding atomic nuclei.
 * The discovery of the nuetron made it possible for physicist to create elements that were heavier than uranium in the lab, and also lead to other great discoveries.
 * Due to this great discovery James Chadwick was awarded with the Hughes Medal of the Royal Society in 1932, and in 1935 he was awarded with the nobel prize for physics.
 * Chadwick took smashed beryllium particles.
 * He allowed the radiation that was released to hit wax paper.
 * When the beryllium atoms, and the hydrogen atoms in the wax paper hit together they released nuetrol particles.
 * Resulting in the discovery of the neutron.



__**Atomic Bomb Study**__
 * Chadwick became professor of physics in 1935.
 * As a result of the Frisch-Peierls memorandum in 1940 on the feasibility of an atomic bomb, he was appointed to the MAUD commitie to investigate the matter further.
 * He visited North America as part of the Tizard Mission in 1940 to collaborate with the Americans and Canadians on nuclear research.
 * Returning to England in November 1940, he concluded that nothing would emerge from this research until after the war.


 * __Recently Found Documents__**
 * In 1940, Chadwick forwarded the work of two French scientists, Hans Von Halban and Lew Kowarski, who worked in Cambridge to the Royal Society.
 * He asked that the papers be held as they were not appropriate for publication during the war.
 * In 2007, the Society discovered the documents during an audit of their archives


 * __James Chadwick's life__**
 * James Chadwick married a lady by the name of Aileen Stewart-Brown of Liverpool.
 * They had twin daughters
 * They lived in Denbigh, North Wales
 * Other than physics James Chadwick enjoyed gardening,fishing, and playing with his children.
