Sir James Chadwick, CH, FRS (20 October 1891 – 24 July 1974) was an English physicist who was awarded the 1935 Nobel Prize in Physics for his discovery of the neutron in 1932. In 1941, he wrote the final draft of the MAUD Report, which inspired the U.S. government to begin serious atom bomb research efforts.
James Chadwick (born October 20, 1891, Manchester, England—died July 24, 1974, Cambridge, Cambridgeshire) was an English physicist who received the Nobel Prize for Physics in 1935 for the discovery of the neutron.
In 1932, Chadwick made a fundamental discovery in the domain of nuclear science: he proved the existence of neutrons – elementary particles devoid of any electrical charge. In contrast with the helium nuclei (alpha rays) which are charged, and therefore repelled by the considerable electrical forces present in the nuclei of heavy atoms, this ...
In 1932, Chadwick made a fundamental discovery in the domain of nuclear science. Chadwick was fascinated by an experiment done by Frdric and Irne Joliot-Curie that studied the then-unidentified radiation from beryllium as it hit a paraffin wax target.

The essential nature of the atomic nucleus was established with the discovery of the neutron by James Chadwick in 1932 [6] and the determination that it was a new elementary particle, distinct from the proton.
The English physicist Sir James Chadwick (1891-1974) made his most outstanding contribution to modern physics by demonstrating the existence of the neutron. James Chadwick was born in Manchester on Oct. 20, 1891, the eldest son of John Joseph and Anne Mary Knowles Chadwick.
