In the summer of 1941, Chadwick wrote a report that summarized all of the nuclear weapon research done in the UK, called the Military Applications of Uranium Detonation (MAUD) report. President Roosevelt read this report, and soon after, the US government began the Manhattan Project to develop the atomic bomb.

After the war ended, he was appointed to the the UK Advisory Committee on Atomic Energy (ACAE) and the United Nations Atomic Energy Commission. In 1948, he accepted the position of Master of Gonville and Caius College, where he did his Ph.D. The academic reputation of the college increased dramatically during his Mastership, due to the increase in the number of research fellowships and the hiring of controversial faculty. It was during his tenure that Francis Crick and James Watson discovered the double helix structure of DNA. He remained in this position until his retirement in 1959. He passed away peacefully in his sleep on July 24, 1974 at his home in Cambridge.</div></td></tr>
