  James Chadwick - Biography
James Chadwick was born in Cheshire, England, on 20th October, 1891, the son of John Joseph Chadwick and Anne Mary Knowles.
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 new tool in atomic disintegration need not overcome any electric barrier and is capable of penetrating and splitting the nuclei of even the heaviest elements.
Chadwick has had many papers published on the topic of radioactivity and connected problems and, with Lord Rutherford and C. Ellis, he is co-author of the book Radiations from Radioactive substances (1930).

  James Chadwick
Chadwick was born in Manchester, England and educated at Manchester University[?] and Cambridge University.
In 1932 Chadwick made a fundamental discovery in the domain of nuclear science[?]: he discovered the particle in the nucleus of an atom that became known as the neutron because it has no electric charge.
Chadwick became professor of Physics at Liverpool University in 1935 and during the Second World War he joined the Manhattan Project in the United States, developing the atomic bombs dropped on Hiroshima and Nagasaki.

 James Chadwick Summary
James Chadwick was born in Manchester on Oct. 20, 1891, the eldest son of John Joseph and Anne Mary Knowles Chadwick.
Chadwick showed, by using a cloud chamber filled with nitrogen, that the radiation caused the nitrogen atoms to recoil with such energy as could be imparted only by collisions with uncharged particles having approximately the mass of protons.
James Chadwick, the son of John Joseph Chadwick and Anne Mary Knowles, was born in Cheshire, an English mill town, and later moved with his family to Manchester.

Consequently, Justice Chadwick was deprived of critical information and knowledge with which to situate the conduct, demeanor and testimony of the witnesses against the serious allegations of non-disclosure put forth by defence.
Finally, I respectfully submit that, in granting the stay, Justice Chadwick was attempting in part to exonerate Justice McKinnon by sparing him the embarrassment of recusal and the concurrent legal disgrace of declaring a mistrial.
Justice Chadwick indicated that he opted against a mistrial because it would be “a tremendous hardship” on the victims and other witnesses to testify again.

 James Chadwick
Chadwick in collaboration with Rutherford realized that the atomic mass of most elements was about double the number of protons.
Chadwick realized that some of their experiments might be used to find the elusive neutron, so he repeated their experiments with this goal in mind.
In 1932, he found definitive evidence for the existence of a neutral particle that had roughly the same mass as a proton.
