Executive summary: Discovered the neutron

In 1932, while working under Ernest Rutherford at Cambridge, James Chadwick proved the existence of neutrons, the elementary particle without any electrical charge and a fundamental building block of the atom's nucleus. One of the most important scientific discoveries of the twentieth century, it effectively solved the jigsaw puzzle of the atom, and earned Chadwick the 1935 Nobel Prize for Physics. Following Chadwick's breakthrough, he and other scientists began experimenting on all types of materials with neutrons, leading to the discovery of nuclear fission when uranium is bombarded with neutrons, and the eventual development of nuclear weapons and nuclear power production.

He studied under Hans Geiger, and at the outbreak of World War I he was working in Germany, where he was imprisoned for the duration of that war. At his 1925 wedding, his best man was Pyotr Kapitsa. During World War II he came to America, where he contributed to the Manhattan Project that developed the world's first atomic weapons. He was knighted in 1945, and passed away in 1974.
