On February 27, 1932, English physicist and Nobel Laureate Sir James Chadwick published an article in the scienticic journal 'Nature' about the discovery of the neutron, a previously unknown particle in the atomic nucleus.
On December 20, 1910, New Zealand born physicist Ernest Rutherford made his seminal gold foil experiment which led to first insight about the nature of the inner structure of the atom and to the postulation of Rutherford's concept of the "nucleus", his greatest contribution to physics. Most interestingly, Rutherford made his greatest discovery after receiving the Nobel Prize in chemistry in 1908.
