Today in Engineering History April 14, 1932 - Two physicists, Englishman Sir John Douglas Cockcroft and Irishman Ernest Walton developed the first nuclear particle accelerator, the Cockcroft-Walton generator. With this equipment, they succeeded in being the first to split the nucleus of an atom. When a proton from the beam supplied by the accelerator struck a lithium nucleus, their unstable combination disintegrated into two alpha particles (helium nuclei). They shared the 1951 Nobel Prize in Physics for this work.
