Biography
John Cockcroft pioneered nuclear physics by designing the first particle accelerator that successfully split an atomic nucleus in 1932, proving Einstein's massenergy equivalence experimentally. His groundbreaking work with Ernest Walton earned the Nobel Prize and laid the foundation for nuclear energy and weapons research. He later became a leading scientific statesman, advocating for peaceful atomic applications and international scientific cooperation.
