James+Chadwick

James Chadwick is one tough guy. Not only did he study with the baddest of the bad (Ernest Rutherford), but he was taken to Rhuleben P.O.W. camp in WWI where he set up his own lab in the stables where he worked on the ionization of phosphorus and the reaction of carbon monoxide (CO) and Chlorine (Cl). He is credited with discovering the Neutron, but that's not all. This discovery lead to such discoveries as nuclear fission and made it possible to create elements heavier than uranium. This addition to the field of Physics got him knighted in 1932 and a nobel prize in 1935.
