John Cockcroft (1897–1967)
Born 1897 CE, died 1967 CE.
Sir John Douglas Cockcroft (27 May 1897 – 18 September 1967) 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 nuclear power and weapons. After service on the Western Front with the Royal Field Artillery during the Great War, Cockcroft studied electrical engineering at Manchester Municipal College of Technology whilst he was an apprentice at Metropolitan Vickers Trafford Park and was also a member of their research staff. He then won a scholarship to St John's College, Cambridge, where he sat the Tripos exam in June 1924, becoming a Wrangler. Ernest Rutherford accepted Cockcroft as a research student in the Cavendish 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.
