James Chadwick (1891-1974) was awarded the Nobel Prize for Physics in 1935 for his discovery of the particle in the nucleus of an atom known as the neutron.
Born in Cheshire, he graduated from Manchester University and won a scholarship in 1913 to work under Professor Geiger in Germany. He became a prisoner of war in Germany for the duration of World War 1, but was then able to return to England to rejoin the mentor of his undergraduate days, Ernest Rutherford, in Cambridge University's nuclear physics lab. He was Professor of Physics at Liverpool University from 1935 to 1948 (with three years on the Manhattan Project in the USA) and was then elected Master of Gonville and Caius College Cambridge until 1959. In retirement, he was a part-time member of the UK Atomic Energy Authority.
James Chadwick became a Fellow of the Royal Society in 1927 and was knighted in 1945.
