John Cockcroft (1897–1967) was a notable British physicist, best known for his contributions to nuclear physics and the development of particle accelerators. Along with Ernest Walton, he was awarded the Nobel Prize in Physics in 1951 for their pioneering work in artificial nuclear reactions. They achieved this by accelerating protons to collide with lithium, resulting in the disintegration of the lithium nuclei and the release of alpha particles.
