Norman Feather FRS FRSE PRSE (16 November 1904, Pecket Well, Yorkshire – 14 August 1978, Christie Hospital, Manchester),〔(Wilkinson: ''Feather, Norman (1904–1978)'', rev. Oxford Dictionary of National Biography, Oxford University Press, 2004; online edn, Oct 2009, accessed 26 Jan 2013 )〕 was an English nuclear physicist. Feather and Egon Bretscher were working at the Cavendish Laboratory, Cambridge in 1940, when they proposed that the 239 isotope of element 94 (plutonium) would be better able to sustain a nuclear chain reaction. This research, a breakthrough, was part of the Tube Alloys project, the secret British project during World War II to develop nuclear weapons. Feather was the author of a series of noted introductory texts on the history, fundamental concepts, and meaning of physics. ==Early life and education== His father was headmaster at his first school. He was then educated at Bridlington Grammar School and Trinity College, Cambridge, becoming a Fellow of Trinity College from 1929 to 1933 then Fellow and Lecturer in Natural Sciences there from 1936 to 1945. Feather received his doctorate at Cambridge in 1931 under James Chadwick and Ernest Rutherford. His research employed a Wilson cloud chamber and focused on the problem of the long-range alpha particles.
