Career And Professional Highlights

Best Known For...

During World War I, James Chadwick was imprisoned in Ruhleben's Zivilgefangenenlager. In 1919, he returned to England to begin his Wollaston Studentship at Cambridge's Gonville and Caius College.

Chadwick decided to restart his work under Rutherford. He had relocated to the Cavendish Laboratory in Cambridge in the meantime. Rutherford had disintegrated atoms that year by blasting nitrogen with alpha particles. This resulted in the emission of a proton. This was the world's first artificial nuclear reaction.

In Cambridge, Chadwick worked with Rutherford on the transmutation of additional light elements using alpha particles. They also researched the characteristics and structure of atomic nuclei.

Chadwick became Assistant Director of Research in the Cavendish Laboratory after being elected Fellow of Gonville and Caius College. He was also elected a Fellow of the Royal Society in 1927.

Chadwick achieved a breakthrough in nuclear science in 1932. He confirmed the existence of neutrons. Chadwick explained that neutrons are elementary particles that have no electrical charge. This changed the atomic model.

Chadwick paved the path for the fission of uranium 235 and the development of the atomic bomb in this fashion. He received the Hughes Medal of the Royal Society in 1932 and the Nobel Prize in Physics in 1935 for this groundbreaking discovery.

Chadwick stayed in Cambridge until 1935. He was then appointed to the University of Liverpool's Lyon Jones Chair of Physics. Chadwick served as the Head of the British Mission linked to the Manhattan Project to develop the atomic bomb in the United States from 1943-1946.

Chadwick was appointed as Master of Gonville and Caius College, Cambridge. In 1948, he resigned from active physics and his job at Liverpool. He was a part-time member of the United Kingdom Atomic Energy Authority from 1957-1962.

Chadwick has authored several studies on radioactivity and related issues. With Lord Rutherford and C. D. Ellis, he co-wrote the book 'Radiations From Radioactive Substances.'

What awards did James Chadwick win?

In 1945, Sir James Chadwick was knighted. He also earned the Copley Medal and the Franklin Medal from the Franklin Institute in Philadelphia.

James Chadwick is an Honorary Fellow of the Institute of Physics and a member of several foreign academies.
