Sir James Chadwick, (20 October 1891 – 24 July 1974) was a British 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 atomic bomb research efforts. He was the head of the British team that worked on the Manhattan Project during World War II. He was knighted in Britain in 1945 for his achievements in physics. Chadwick graduated from the Victoria University of Manchester in 1911, where he studied under Ernest Rutherford (known as the "father of nuclear physics").

In early 1944, he moved to Los Alamos, New Mexico, with his wife and their twins, who now spoke with Canadian accents. For security reasons, he was given the cover name of James Chaffee. Chadwick accepted that the Americans did not need British help, but that it could still be useful in bringing the project to an early and successful conclusion. Working closely with the director of the Manhattan Project, Major General Leslie R. Groves, Jr., he attempted to do everything he could to support the effort. He also endeavoured to place British scientists in as many parts of the project as possible in order to facilitate a post-war British nuclear weapons project to which Chadwick was committed.

Requests from Groves via Chadwick for particular scientists tended to be met with an immediate rejection by the company, ministry or university currently employing them, only to be overcome by the overriding priority accorded to Tube Alloys. As a result, the British team was critical to the Project's success.

The matter of cooperation had to be taken up at the highest level. In September 1943, the Prime Minister, Winston Churchill, and President Roosevelt negotiated the Quebec Agreement, which reinstated cooperation between Britain, the United States and Canada. Chadwick, Oliphant, Peierls and Simon were summoned to the United States by the director of Tube Alloys, Sir Wallace Akers, to work with the Manhattan Project. The Quebec Agreement established a new Combined Policy Committee to direct the joint project. The Americans disliked Akers, so Chadwick was appointed technical advisor to the Combined Policy Committee, and the head of the British Mission.

Sir James Chadwick, (20 October 1891 – 24 July 1974) was a British 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 atomic bomb research efforts.

Chadwick graduated from the Victoria University of Manchester in 1911, where he studied under Ernest Rutherford (known as the "father of nuclear physics").
James Chadwick | Introduction
Leaving Rotblat in charge in Liverpool, Chadwick began a tour of the Manhattan Project facilities in November 1943, except for the Hanford Site where plutonium was produced, which he was not allowed to see. He became the only man apart from Groves and his second in command to have access to all the American research and production facilities for the uranium bomb. Observing the work on the K-25 gaseous diffusion facility at Oak Ridge, Tennessee, Chadwick realised how wrong he had been about building the plant in wartime Britain. The enormous structure could never have been concealed from the Luftwaffe.

Gen 75 Committee | Background
He was given an apartment at St James's Palace and an office with the British Tube Alloys nuclear weapons development team. Bohr was astonished at the amount of progress that had been made. Chadwick arranged for Bohr to visit the United States as a Tube Alloys consultant, with Aage as his assistant. On 8 December 1943, Bohr arrived in Washington, D.C., where he met with the director of the Manhattan Project, Brigadier General Leslie R. Groves, Jr. He visited Einstein and Pauli at the Institute for Advanced Study in Princeton, New Jersey, and went to Los Alamos in New Mexico, where the nuclear weapons were being designed.

As overall head of the British contribution to the Manhattan Project, James Chadwick forged a close and successful partnership with the Americans, and ensured that British participation was complete and wholehearted. After the war ended, the Special Relationship between Britain and the United States "became very much less special". The British government had trusted that America would continue to share nuclear technology, which it considered a joint discovery, but little information was exchanged immediately after the war, and the Atomic Energy Act of 1946 (McMahon Act) officially ended technical cooperation. Its control of "restricted data" prevented the United States' allies from receiving any information.
Windscale fire | Background
Owing to the danger from aerial bombardment, the Chadwicks sent their twins to Canada as part of a government evacuation scheme. Chadwick was reluctant to move Tube Alloys there, believing that the United Kingdom was a better location for the isotope separation plant. The enormous scope of the effort became more apparent in 1942: even a pilot separation plant would cost over £1 million and strain Britain's resources, to say nothing of a full-scale plant, which was estimated to cost somewhere in the vicinity of £25 million. It would have to be built in America. At the same time that the British became convinced that a joint project was necessary, the progress of the American Manhattan Project was such that British cooperation seemed less essential, although the Americans were still eager to utilise Chadwick's talents.
James Chadwick | Manhattan Project
With this dispute settled collaboration could once again take place. Chadwick wanted to involve as many British scientists as possible so long as Groves accepted them. Chadwick's first choice, Joseph Rotblat refused to give up his Polish citizenship. Chadwick then turned to Otto Frisch, who to Chadwick's surprise accepted becoming a British citizen right away and began the screening process so he could travel to America. Chadwick spent the first few weeks of November 1943 acquiring a clear picture of the extensive Manhattan Project. He realised the scale of such sites as Oak Ridge, Tennessee, which was the new headquarters of the project, and could safely conclude that without similar industrial site being found in Germany the chances of the Nazi atomic bomb project being successful was very low.

Don Chadwick | Introduction
Akers summoned Chadwick, Oliphant, Simon and Peierls to the United States. They arrived the day the Quebec Agreement was signed, ready to assist the Manhattan Project in any way possible. Akers was generally disliked and the Americans refused to move forward with collaboration unless a top British scientist who was "accepted and sound of judgement" was appointed instead. British officials dug in over Britain's right to make its own appointments to its own government agencies. A compromise was reached, with Chadwick put in charge as Britain's technical advisor for the Combined Policy Committee, and as the head of the British Mission to the Manhattan Project.

Another, led by Oliphant, who acted as deputy director at the Berkeley Radiation Laboratory, assisted with the electromagnetic separation process. Cockcroft became the director of the Anglo-Canadian Montreal Laboratory. The British mission to the Los Alamos Laboratory was headed by Chadwick, and later Peierls. It included distinguished scientists such as Geoffrey Taylor, James Tuck, Niels Bohr, William Penney, Frisch, Ernest Titterton and Klaus Fuchs, who was later revealed to be a Soviet spy. As overall head of the British Mission, Chadwick forged a close and successful partnership with Brigadier General Leslie R. Groves, the director of the Manhattan Project.

The Quebec Agreement established the Combined Policy Committee and the Combined Development Trust to coordinate the efforts of the United States, the United Kingdom and Canada. The subsequent Hyde Park Agreement in September 1944 extended this cooperation to the postwar period. A British Mission led by Wallace Akers assisted in the development of gaseous diffusion technology in New York. Britain also produced the powdered nickel required by the gaseous diffusion process. Another mission, led by Oliphant who acted as deputy director at the Berkeley Radiation Laboratory, assisted with the electromagnetic separation process. As head of the British Mission to the Los Alamos Laboratory, James Chadwick led a multinational team of distinguished scientists that included Sir Geoffrey Taylor, James Tuck, Niels Bohr, Peierls, Frisch, and Klaus Fuchs, who was later revealed to be a Soviet atomic spy.

Chadwick was born in Brooklyn, New York, in June 1880. His father Charles Noyes Chadwick was the president of C.N. Chadwick Co., manufacturers of children's underwaists and boy's shirtwaists. His mother was Alice Ann (Caruth) Chadwick was born in Northern Ireland. Chadwick attended the Froebel Academy, Brooklyn Latin School and Brooklyn High School.
George B. Chadwick | Early years
By March 1943 Conant decided that British help would benefit some areas of the project. In particular, the Manhattan Project could benefit enough from assistance from James Chadwick, the discoverer of the neutron, and several other British scientists to warrant the risk of revealing weapon design secrets. Bush, Conant and Groves wanted Chadwick and Peierls to discuss bomb design with Robert Oppenheimer, and Kellogg still wanted British comments on the design of the gaseous diffusion plant. Churchill took up the matter with Roosevelt at the Washington Conference on 25 May 1943, and Churchill thought that Roosevelt gave the reassurances he sought; but there was no follow-up.

Shortly after the war ended, Chadwick was appointed to the Advisory Committee on Atomic Energy (ACAE). He was also appointed as the British scientific advisor to the United Nations Atomic Energy Commission. He clashed with fellow ACAE member Patrick Blackett, who disagreed with Chadwick's conviction that Britain needed to acquire its own nuclear weapons; but it was Chadwick's position that was ultimately adopted. He returned to Britain in 1946, to find a country still beset by wartime rationing and shortages. At this time, Sir James Mountford, the Vice Chancellor of the University of Liverpool, wrote in his diary "he had never seen a man 'so physically, mentally and spiritually tired" as Chadwick, for he "had plumbed such depths of moral decision as more fortunate men are never called upon even to peer into ...

James Dunkerley | Introduction
With Chadwick involved the main goal was to show that the Quebec Agreement was a success. It was Britain's duty to co-operate to the fullest and speed along the process. Chadwick used this opportunity to give as many young British scientists experience as possible so they might carry that experience to post-war Britain. He eventually convinced Groves of Rotblat's integrity to the cause, and this led to Rotblat being accepted to the Manhattan Project without renouncing his nationality. Rotblat had been left in charge of the Tube Alloys research, and brought with him the results obtained since Chadwick had left.

He now had two younger brothers, Harry and Hubert; a sister had died in infancy. At the age of 16, he sat two examinations for university scholarships, and won both of them. Chadwick chose to attend Victoria University of Manchester, which he entered in 1908. He meant to study mathematics, but enrolled in physics by mistake. Like most students, he lived at home, walking the to the university and back each day. At the end of his first year, he was awarded a Heginbottom Scholarship to study physics. The physics department was headed by Ernest Rutherford, who assigned research projects to final-year students, and he instructed Chadwick to devise a means of comparing the amount of radioactive energy of two different sources.

He was Rutherford's assistant director of research at the Cavendish Laboratory for over a decade at a time when it was one of the world's foremost centres for the study of physics, attracting students like John Cockcroft, Norman Feather, and Mark Oliphant. Chadwick followed his discovery of the neutron by measuring its mass. He anticipated that neutrons would become a major weapon in the fight against cancer. Chadwick left the Cavendish Laboratory in 1935 to become a professor of physics at the University of Liverpool, where he overhauled an antiquated laboratory and, by installing a cyclotron, made it an important centre for the study of nuclear physics.

Chadwick's Clerk-Maxwell studentship expired in 1923, and he was succeeded by the Russian physicist Pyotr Kapitza. The Chairman of the Advisory Council of the Department of Scientific and Industrial Research, Sir William McCormick arranged for Chadwick to become Rutherford's assistant director of research. In this role, Chadwick helped Rutherford select PhD students. Over the next few years these would include John Cockcroft, Norman Feather and Mark Oliphant, who would become firm friends with Chadwick. As many students had no idea what they wanted to research, Rutherford and Chadwick would suggest topics. Chadwick edited all the papers produced by the laboratory.

Chadwick promptly hired Rotblat as a lecturer, despite his poor grasp of English. In October 1939, Chadwick received a letter from Sir Edward Appleton, the Secretary of the Department of Scientific and Industrial Research, asking for his opinion on the feasibility of an atomic bomb. Chadwick responded cautiously. He did not dismiss the possibility, but carefully went over the many theoretical and practical difficulties involved. Chadwick decided to investigate the properties of uranium oxide further with Rotblat. In March 1940, Otto Frisch and Rudolf Peierls at the University of Birmingham re-examined the theoretical issues involved in a paper that became known as the Frisch–Peierls memorandum.

While still in Poland, Rotblat had realised that nuclear fission might possibly be used to produce an atomic bomb. He first thought that he should "put the whole thing out of my mind", but he continued because he thought the only way to prevent Nazi Germany from using a nuclear bomb was if Britain had one to act as a deterrent. He worked with Chadwick on Tube Alloys, the British atomic bomb project. In February 1944, Rotblat joined the Los Alamos Laboratory as part of Chadwick's British Mission to the Manhattan Project. The usual condition for people to work on the Manhattan Project was that they had to become US citizens or British subjects.

By April 1941, it had been experimentally confirmed that the critical mass of uranium-235 might be or less. His research into such matters was complicated by all-but-incessant Luftwaffe bombings of the environs of his Liverpool lab; the windows were blown out so often that they were replaced by cardboard. In July 1941, Chadwick was chosen to write the final draft of the MAUD Report, which, when presented by Vannevar Bush to President Franklin D. Roosevelt in October 1941, inspired the U.S. government to pour millions of dollars into the pursuit of an atomic bomb. When George B. Pegram and Harold Urey visited Britain to see how the project, now known as Tube Alloys, was going, Chadwick was able to tell them: "I wish I could tell you that the bomb is not going to work, but I am 90 per cent sure that it will."

They investigated the possibility of an independent nuclear program, but determined that it could not be ready in time to affect the outcome of the war in Europe. By March 1943 Conant decided that British help would benefit some areas of the project. James Chadwick and one or two other British scientists were important enough that the bomb design team at Los Alamos needed them, despite the risk of revealing weapon design secrets. In August 1943 Churchill and Roosevelt negotiated the Quebec Agreement, which resulted in a resumption of cooperation between scientists working on the same problem. Britain, however, agreed to restrictions on data on the building of large-scale production plants necessary for the bomb.

With the onset of the Great Depression in the United Kingdom, the government became more parsimonious with funding for science. At the same time, Lawrence's recent invention, the cyclotron, promised to revolutionise experimental nuclear physics, and Chadwick felt that the Cavendish laboratory would fall behind unless it also acquired one. He therefore chafed under Rutherford, who clung to the belief that good nuclear physics could still be done without large, expensive equipment, and turned down the request for a cyclotron. Chadwick was himself a critic of Big Science in general, and Lawrence in particular, whose approach he considered careless and focused on technology at the expense of science.

Ironically, it was the British project that had already been penetrated by atomic spies for the Soviet Union. Yet the United Kingdom did not have the manpower or resources of the United States, and despite its early and promising start, Tube Alloys fell behind its American counterpart and was dwarfed by it.
