Sir John Douglas Cockcroft was a British experimental physicist who shared the 1951 Nobel Prize in Physics with Ernest Walton for their splitting of the atomic nucleus, which led to the development of

The house in Walsden, Todmorden, where Cockcroft lived from the age of two until he was 28-years-old.
The Cockcroft–Walton generator, or multiplier, is an electric circuit that generates a high DC voltage from a low-voltage AC. It was named after the British and Irish physicists John Douglas Cockcroft

…Laboratory, and Cockcroft completed his doctorate under Rutherford's supervision in 1928. With Walton and Mark Oliphant, he built what became known as a Cockcroft–Walton generator. Cockcroft and Walton used this to perform the first artificial disintegration of an atomic nucleus, a feat popularly known as "splitting the atom…
This Cockcroft–Walton particle accelerator was used during the development of the atomic bomb. Built in 1937 by Philips of Eindhoven it is now in the National Science Museum in London, England.
