Background
Sir James Chadwick was a very educated scientist who was famous for his discoveries of the neutron. He studied in the lab under Ernest Rutherford, who won the Nobel Prize for physics in 1908. He worked under Rutherford until he was 21, when he earned his Master's Degree in physics.
In 1912, he was awarded a scholarship to go to Berlin, Germany, and study in a lab under Hans Geiger. After being held in Germany from 1914, to 1918, he came back to Rutherford, who was now in the Cavendish Laboratory, and started working for his Ph.D. degree. He was awarded his Ph.D in 1921 regarding a thesis concerning atomic numbers and nuclear forces.
At age 32 in 1923, Chadwick was Rutherford's Assistant Director of Research, and continued to study the atomic nucleus. Three years ago in the 1920, he was becoming increasingly convinced that there was such thing as neutral particles. Then, it happened. Chadwick learned a lot of work that was done with Frederic and Irene Joliet-Curie in Paris. This involved ejecting protons from a sample wax using gamma rays. Then, he took some experiments, and founded the neutron.
