(1891–1974) British physicist.
After working at Manchester University under Rutherford, he went to work with Hans Geiger in Leipzig in 1913. Interned for the duration of World War I, he joined Rutherford in Cambridge after the war. In 1932 he discovered the neutron, as predicted by Rutherford. In 1935 he was awarded the Nobel Prize, the same year in which he built Britain's first cyclotron at Liverpool University.
