[[Knight Bachelor|Sir]] '''Charles Drummond Ellis''' (b.Hampstead, 11 August 1895; died Cookham 10 January 1980) was a [[physicist]] and scientific administrator. His work helped scientists to understand [[nuclear]] structure better. ==Education and internment== Ellis's father was a general manager of the Metropolitan Railway in [[London]]. He went to [[Harrow School]] where he was very good at all subjects as well as sport. In 1913 he become a [[cadet]] in the [[Royal Military Academy]]. He wanted to join the [[Royal Engineers]].

There were lots of stables, and in each stable there were 27 horse boxes which became the detainees' home during the war. The detainees were allowed to do lots of things to keep themselves busy. They could get books, and Ellis made good use of his time to study. Another detainee in the camp was the scientist [[James Chadwick]]. Chadwick taught Ellis a lot and together they made a laboratory in one of the horse stables where they made scientific experiments on the [[photochemical]] process. ==Career after the war== After the war Ellis decided to study at [[Trinity College, Cambridge]]. After graduating in [[1920]] he did research work at the [[Cavendish Laboratory]], [[Cambridge]]. The director there was Sir [[Ernest Rutherford]]. Chadwick also worked there. In [[1921]] Ellis had become a fellow of Trinity College and was made assistant lecturer in natural science. In 1925 he married the daughter of a rich Polish [[shipbuilder]]. In 1929 he was elected a fellow of the [[Royal Society]]. In 1930 Rutherford, Chadwick and Ellis wrote a famous book together called ''Radiations from Radioactive Substances''. ==Discovery of the neutrino== During the early 1930s Ellis worked with N.F.Mo
