=James Chadwick=

20 October 1891 – 24 July 1974 Of English decent years of work: 1932 [] Born in Cheshire, England, James Chadwick attended Manchester college and graduated in 1911 from the Honors School of Physics. Dureing World War One he was intured in the Zivilgefangenenlager POW camp just outside of Berlin, but was allowed to set up a lab in the stables and conducted inonization expiriments for the duration of the war. After the armestice he returned to England and worked under Rutherford. In World War Two he was a member of the Manhattan Project, America's effort to built an atomic weapon. In 1925 he married and had two daughters with his wife. His hobbies included gardening and fishing.

Chadwick is most famous for his work in the advancement of nuclear fission, spicifically for the discovery of the Neutron. He was responsible for the first artificial nuclear reaction when he disintegrated nitrogen atoms by bombarding them with alpha particals (protons). However when he tried to replicate his results with more massive atoms, the postivly charged particals could not approach their dense positive nucli. Through experimentation, he discovered a subatomic particle that had no reaction to the postive charge and could split even the largest of nucli. Ne named the partical the Neutron after the latin root for neutral. For this discovery, he was awarded the Nobel Prize in Physics in 1935. [] []
