Chadwick had been working in Hans Geiger's laboratory to determine the status of beta-particle emissions. Before Chadwick had turned twenty-three years old, he would publish a paper on how he was able to determine that there was a continuous beta spectrum (but "up to a certain limit") rather than a set of discrete lines, as had been heretofore accepted, due to work by Meitner and Hahn; this discovery, would have given him a place in physics history had he done nothing thereafter. Other physicists would miss its significance, but not Einstein. That Spring, he visited the lab to hear Chadwick explain in German his findings, at which time Einstein responded "I can explain either of these things, but I can't explain them both at the same time," referring to the spectrum vs. the "certain limit." This discovery has been called a "turning point" in modern physics (see Burton Feldman letter below).਀㰀⼀瀀㸀㰀瀀㸀 ....
Months later, after Britain declared war on Germany, Chadwick was interned as an enemy alien in racehorse stables west of Berlin; throughout this ordeal he suffered from malnutrition, leaving him in poor health for much of the rest of his life. The Germans did allow him to continue his research, and he employed, among other things, German radioactive toothpaste! Besides, he did thus escape the fate of many in his generation, who had to endure the horrors of trench warfare; he would feel some guilt for gaining this bit of luck, such as it was.਀⸀⸀⸀⸀ 㰀⼀戀爀㸀㰀戀爀㸀䰀椀戀攀爀愀琀攀搀 愀昀琀攀爀 琀栀攀 ㄀㤀㄀㠀 愀爀洀椀猀琀椀挀攀Ⰰ 栀攀 眀愀猀 猀眀椀昀琀氀礀 栀椀爀攀搀 戀礀 刀甀琀栀攀爀昀漀爀搀 愀琀 琀栀攀 䌀愀瘀攀渀搀椀猀栀 䰀愀戀漀爀愀琀漀爀礀Ⰰ 䌀愀洀戀爀椀搀最攀⸀ 吀栀攀爀攀 䌀栀愀搀眀椀挀欀 猀甀挀挀攀攀搀攀搀 椀渀 瀀爀漀瘀椀渀最 琀栀攀 挀漀爀爀攀挀琀渀攀猀猀 漀昀 刀甀琀栀攀爀昀漀爀搀✀猀 琀栀攀漀爀礀Ⰰ 琀栀愀琀 愀渀 攀氀攀洀攀渀琀✀猀 愀琀漀洀椀挀 渀甀洀戀攀爀 椀猀 攀焀甀愀氀 琀漀 琀栀攀 挀栀愀爀最攀 漀昀 椀琀猀 渀甀挀氀攀甀猀Ⰰ 椀攀⸀ 琀栀愀琀 瀀爀漀琀漀渀猀 攀砀椀猀琀⸀ 䠀攀 爀攀挀攀椀瘀攀搀 栀椀猀 倀栀⸀䐀⸀ 椀渀 ㄀㤀㈀㄀Ⰰ 愀渀搀 琀栀愀琀 礀攀愀爀 戀爀漀甀最栀琀 栀椀猀 猀攀挀漀渀搀 洀愀樀漀爀 挀漀渀琀爀椀戀甀琀椀漀渀Ⰰ 眀栀攀渀 栀攀 愀渀搀 䔀⸀匀⸀ 䈀椀攀氀攀爀 搀攀琀攀爀洀椀渀攀搀 琀栀愀琀 猀漀洀攀 ∀猀琀爀漀渀最 昀漀爀挀攀∀ 栀漀氀搀猀 琀栀攀 渀甀挀氀攀甀猀 琀漀最攀琀栀攀爀Ⰰ 愀 昀漀爀挀攀 搀椀猀琀椀渀挀琀 昀爀漀洀 琀栀攀 攀氀攀挀琀爀漀洀愀最渀攀琀椀猀洀 眀栀椀挀栀 栀愀搀 戀攀攀渀 甀瀀 甀渀琀椀氀 琀栀攀渀 瀀爀攀猀甀洀攀搀 琀漀 戀攀 愀挀栀椀攀瘀椀渀最 琀栀椀猀 栀漀氀搀椀渀最 攀昀昀攀挀琀㬀 琀栀攀 猀攀愀爀挀栀 猀椀渀挀攀 圀圀䤀䤀 昀漀爀 愀 ∀琀栀攀漀爀礀 漀昀 攀瘀攀爀礀琀栀椀渀最∀ 琀爀椀攀猀 琀漀 愀挀挀漀甀渀琀 昀漀爀 琀栀攀 爀攀氀愀琀椀漀渀猀栀椀瀀 戀攀琀眀攀攀渀 琀栀椀猀 昀漀爀挀攀Ⰰ ∀琀栀攀 眀攀愀欀 昀漀爀挀攀Ⰰ∀ 最爀愀瘀椀琀礀Ⰰ 愀渀搀 攀氀攀挀琀爀漀洀愀最渀攀琀椀猀洀⸀ 吀栀椀猀 愀挀栀椀攀瘀攀洀攀渀琀 椀猀 挀漀渀猀椀搀攀爀攀搀 漀渀攀 漀昀 琀栀攀 昀攀眀 搀漀稀攀渀 洀椀氀攀猀琀漀渀攀猀 椀渀 琀栀攀 栀椀猀琀漀爀礀 漀昀 焀甀愀渀琀甀洀 瀀栀礀猀椀挀猀⸀ ⠀䄀最愀椀渀Ⰰ 猀攀攀 䘀攀氀搀洀愀渀 氀攀琀琀攀爀⤀ ....

In 1923 Chadwick was named Cavendish's (first ever) Assistant Director of Physics Research, becoming the de facto Director as Rutherford aged. In 1925 he married Aileen Stewart-Brown, daughter of a prominent stockbroker on the Liverpool exchange; in 1927 were born twin daughters, with Chadwick earning a reputation as a committed father, balanced with his growing responsibilities to science and society. After searching eight years, and, in 1932, "working day and night for three legendary weeks," (as put by the official historian of the British Atomic Energy Authority) he discovered the neutron in 1932, and, largely for this achievement, would always be known as the ideal experimentalist; this discovery is generally considered to be one of the 100 most significant events in the history of science, and made Page One of the New York Times. Madame Curie's daughter might have preceded Chadwick in this, but she incorrectly interpreted her results. (see Special Section "Significance of a Discovery of Neutron in 1932, later" below.) He was renowned, with all at Cambridge who assisted him, for being meticulous in sharing credit for this achievement. He obtained a patent for this discovery, but would allow governments and universities use the neutron for free, but his estate gets a penny for every 1020> neutrons used by commercial reactors to create fission. As it was, this discovery is understood to have transformed physics, since subsequently, protons and neutrons came to be seen as being held together by a newly understood force, the Strong Force.਀⸀⸀⸀⸀ 㰀⼀戀爀㸀㰀戀爀㸀䠀椀猀 一漀戀攀氀 倀爀椀稀攀 眀愀猀 瀀爀攀猀攀渀琀攀搀 漀渀氀礀 琀栀爀攀攀 礀攀愀爀猀 愀昀琀攀爀 琀栀攀 搀椀猀挀漀瘀攀爀礀 眀栀椀挀栀 椀琀 栀漀渀漀爀攀搀㬀 漀渀氀礀 愀 栀愀渀搀昀甀氀 漀昀 瀀栀礀猀椀挀猀 一漀戀攀氀猀 眀攀爀攀 攀瘀攀爀 愀眀愀爀搀攀搀 猀漀 猀漀漀渀 愀昀琀攀爀 琀栀攀 昀攀愀琀猀 昀漀爀 眀栀椀挀栀 琀栀攀 倀爀椀稀攀猀 眀攀爀攀 攀愀爀渀攀搀⸀ 吀栀攀 昀愀洀椀氀礀✀猀 琀爀椀瀀 琀漀 匀琀漀挀欀栀漀氀洀 昀漀爀 琀栀攀 挀攀爀攀洀漀渀礀Ⰰ 愀猀 漀渀攀 洀椀最栀琀 攀砀瀀攀挀琀Ⰰ 瀀甀琀 愀氀氀 洀攀洀戀攀爀猀 ∀椀渀 愀 猀琀愀琀攀 漀昀 栀椀最栀 攀砀挀椀琀攀洀攀渀琀⸀∀ 䤀渀 ㄀㤀㌀㔀 䌀栀愀搀眀椀挀欀 氀攀昀琀 䌀愀洀戀爀椀搀最攀 昀漀爀 琀栀攀 唀渀椀瘀攀爀猀椀琀礀 漀昀 䰀椀瘀攀爀瀀漀漀氀Ⰰ 眀栀攀爀攀 栀攀 甀猀攀搀 栀椀猀 一漀戀攀氀 倀爀椀稀攀 洀漀渀攀礀 琀漀眀愀爀搀 戀甀礀椀渀最 愀 挀礀挀氀漀琀爀漀渀⸀ 吀栀椀猀 洀愀挀栀椀渀攀Ⰰ 椀渀瘀攀渀琀攀搀 愀琀 䈀攀爀欀攀氀攀礀Ⰰ 唀⸀匀⸀䄀⸀ 戀礀 栀椀猀 昀爀椀攀渀搀Ⰰ 䔀爀渀攀猀琀 䰀愀眀爀攀渀挀攀Ⰰ 挀漀甀氀搀 愀挀挀攀氀攀爀愀琀攀 猀甀戀ⴀ愀琀漀洀椀挀 瀀愀爀琀椀挀氀攀猀 洀甀挀栀 昀愀猀琀攀爀 琀栀愀渀 眀愀猀 栀攀爀攀琀漀昀漀爀攀 瀀漀猀猀椀戀氀攀㬀 䌀栀愀搀眀椀挀欀 栀漀瀀攀搀 琀栀愀琀 琀栀椀猀 搀攀瘀椀挀攀Ⰰ 爀攀愀搀礀 椀渀 䨀甀氀礀 ㄀㤀㌀㤀Ⰰ 洀椀最栀琀 昀愀挀椀氀椀琀愀琀攀 攀昀昀椀挀椀攀渀琀 爀攀搀甀挀琀椀漀渀 漀昀 琀甀洀漀爀猀⸀ 一攀甀琀爀漀渀 琀栀攀爀愀瀀礀 愀最愀椀渀猀琀 挀愀渀挀攀爀 眀愀猀 愀氀眀愀礀猀 挀氀漀猀攀 琀漀 栀椀猀 栀攀愀爀琀Ⰰ 愀 昀愀挀琀 瘀攀爀椀昀椀攀搀 琀漀 甀猀 愀琀 伀甀琀猀琀愀渀搀椀渀最 䄀眀愀爀搀猀 戀礀 栀椀猀 搀愀甀最栀琀攀爀 䨀甀搀椀琀栀 椀渀 愀 䴀愀爀挀栀 ㈀    氀攀琀琀攀爀⸀ 䠀攀 愀氀爀攀愀搀礀 眀愀猀Ⰰ 愀猀 漀昀 䘀攀戀爀甀愀爀礀 ㄀㤀㌀㠀Ⰰ 漀渀攀 漀昀 愀 猀椀砀ⴀ洀愀渀 䰀椀瘀攀爀瀀漀漀氀 䌀愀渀挀攀爀 䌀漀洀洀椀猀猀椀漀渀⸀

While Einstein deserves to be seen as the great-grandfather of the Bomb, (owing to e=mc2) Chadwick should be seen as the grandfather or (according to "How the Bomb's creator learned to love the United States," a British review of Dr. Andrew Brown's major biography of Chadwick, The Neutron and the Bomb) the father; Oppenheimer, known in the U.S. as the father of the Bomb, would have remained unknown but for Chadwick's MAUD Report , before which, Oppenheimer later conceded, the U.S. program was a series of desultory committees (which could not make a case to FDR sufficient to persuade him to authorize the massive expenditure required to bring the Manhattan Project to fruition). As pointed out by the "Manhattan Project" page of the web site of the American Museum of Natural History in New York's Einstein exhibit, Einstein was excluded from the Project due to security concerns arising from his Leftist views, so his famous1939 letter to FDR would be the extent of his contribution to the Project; probably Einstein's love for interacting with the media also increased the security risks of his possible inclusion. (His Nobel Prize and other important objects are being exhibited in conjunction with the Hebrew University of Jerusalem.) Actually, even this Einstein contribution is overrated; this 1939 letter led only to the formation of a Uranium Committee chaired by a bureaucrat, Lyman Briggs, whose knowledge of physics would be quite inadequate. Moreover, the venerable McGeorge Bundy agrees with ace American physicist Arthur Compton that "things would have gone faster if Einstein had never written ..." to FDR; this view owes to the fact that the U.S. uranium committee, set up by FDR after Einstein's letter, valued security over scientific progress, and thus excluded foreign-born physicists, including Einstein, and led native-born physicists to presume that all that could be done was being done. ਀⸀ 䄀氀氀 椀渀 愀氀氀Ⰰ 䈀爀椀琀椀猀栀 挀漀渀琀爀椀戀甀琀椀漀渀猀 琀漀 琀栀攀 䴀愀渀栀愀琀琀愀渀 倀爀漀樀攀挀琀 愀爀攀 渀漀琀 最椀瘀攀渀 琀栀攀椀爀 搀甀攀 椀渀 琀栀攀 唀⸀匀⸀Ⰰ 愀猀 昀愀爀 愀猀 䈀爀椀琀椀猀栀 眀爀椀琀攀爀猀 愀爀攀 挀漀渀挀攀爀渀攀搀㬀 琀栀椀猀 洀甀挀栀 椀猀 挀漀渀挀攀搀攀搀 戀礀 䘀攀爀攀渀挀 匀稀愀猀稀 漀昀 琀栀攀 唀⸀ 漀昀 一攀眀 䴀攀砀椀挀漀Ⰰ 眀栀漀Ⰰ 椀渀 䈀爀椀琀椀猀栀 匀挀椀攀渀琀椀猀琀猀 愀渀搀 琀栀攀 䴀愀渀栀愀琀琀愀渀 倀爀漀樀攀挀琀Ⰰ 愀爀最甀攀猀 琀栀愀琀 琀栀攀 猀椀最渀椀昀椀挀愀渀挀攀 漀昀 琀栀椀猀 挀漀渀琀爀椀戀甀琀椀漀渀 眀愀猀 洀愀琀挀栀攀搀 漀渀氀礀 戀礀 琀栀攀 猀椀最渀椀昀椀挀愀渀挀攀 漀昀 ㄀⤀㨀 唀⸀匀⸀ 洀漀渀攀礀Ⰰ ㈀⤀ 伀瀀瀀攀渀栀攀椀洀攀爀✀猀 愀戀椀氀椀琀礀 琀漀 椀渀猀瀀椀爀攀Ⰰ 愀渀搀 ㌀⤀ 倀爀漀樀攀挀琀 挀漀洀洀愀渀搀攀爀 䜀攀渀⸀ 䰀攀猀氀椀攀 䜀爀漀瘀攀猀✀ 搀爀椀瘀攀⸀ 吀栀攀 漀渀氀礀 唀⸀匀⸀ 猀琀愀琀攀猀洀愀渀 琀漀 最椀瘀攀 琀栀攀 䈀爀椀琀椀猀栀 琀栀攀椀爀 搀甀攀 眀愀猀 䈀甀渀搀礀Ⰰ 瀀愀爀琀椀挀甀氀愀爀氀礀 椀渀 栀椀猀 挀栀愀瀀琀攀爀猀 漀渀 ∀䠀漀眀 琀栀攀 䄀洀攀爀椀挀愀渀猀 圀攀渀琀 䘀椀爀猀琀∀ 愀渀搀 ∀吀栀攀 䄀洀攀爀椀挀愀渀猀 愀渀搀 吀栀攀椀爀 圀愀爀琀椀洀攀 䄀氀氀椀攀猀∀ 椀渀 栀椀猀 戀漀漀欀 䐀愀渀最攀爀 愀渀搀 匀甀爀瘀椀瘀愀氀㨀 䌀栀漀椀挀攀猀 愀戀漀甀琀 琀栀攀 䈀漀洀戀 椀渀 琀栀攀 䘀椀爀猀琀 䘀椀昀琀礀 夀攀愀爀猀Ⰰ 眀栀椀挀栀 洀愀欀攀猀 昀愀猀挀椀渀愀琀椀渀最 爀攀愀搀椀渀最㬀 琀栀攀猀攀 挀栀愀瀀琀攀爀猀 眀漀甀氀搀 戀攀 眀漀爀琀栀 爀攀瀀爀漀搀甀挀椀渀最 椀渀 昀甀氀氀 栀攀爀攀 眀攀爀攀 琀栀椀猀 眀攀戀 瀀愀最攀 渀漀琀 搀攀瘀漀琀攀搀 猀漀 猀瀀攀挀椀昀椀挀愀氀氀礀 琀漀 䌀栀愀搀眀椀挀欀Ⰰ 眀栀漀 䈀甀渀搀礀 挀愀氀氀攀搀 ∀瀀爀攀攀洀椀渀攀渀琀 愀洀漀渀最 䈀爀椀琀椀猀栀 渀甀挀氀攀愀爀 瀀栀礀猀椀挀椀猀琀猀∀ 椀渀 圀圀䤀䤀⸀ 吀栀攀 漀渀氀礀 洀愀樀漀爀 愀猀瀀攀挀琀 漀昀 䌀栀愀搀眀椀挀欀✀猀 爀攀瀀甀琀愀琀椀漀渀 渀漀琀 爀攀昀攀爀爀攀搀 琀漀 戀礀 䈀甀渀搀礀 眀愀猀 䌀栀愀搀眀椀挀欀✀猀 愀戀椀氀椀琀礀 琀漀 猀攀琀 愀渀 攀砀愀洀瀀氀攀 愀猀 愀 琀攀愀洀 瀀氀愀礀攀爀 眀栀漀 愀瘀漀椀搀攀搀 昀愀洀攀

਀ Few stories, esp. in the history of science, combine such high stakes with such dramatic appeal. In what were up to that point the Experiments of the Century, Chadwick would research this Bomb issue in spring 1941 using his cyclotron, while his city, Liverpool, and indeed his Physics Department, were being hammered by the Luftwaffe; in one week 3,000 became casualties and more than 70,000 became homeless. The cyclotron was in the basement, and managed to avoid being hit. Occasionally he would step outside after a German bomb raid to check the city with a Geiger Counter for radioactivity, in case Hitler had already learned how to weaponize uranium. Important though his work was, resources in a Britain under siege were so scarce that he had to fight with the Ministry bureaucracy to get enough funds to be able to afford fuel to travel to even a town near Liverpool, in order to confer with personnel producing weaponizable uranium. He and his wife would move from Upstairs to sleep Downstairs, for safety's sake; the raids were so frequent that the Chadwicks stopped going to the bomb shelter, lest they get to do nothing else but go back and forth. Such conditions would make those encountered by physicists at Los Alamos seem to be blissful by comparison. Every night, the windows, and the cardboard which replaced them, would be blown out. (Their twin daughters had been sent to safety in Nova Scotia in July 1940.) . ਀⸀⸀⸀⸀ 伀昀 琀栀攀 漀琀栀攀爀 猀挀椀攀渀琀椀猀琀猀 椀渀瘀漀氀瘀攀搀 椀渀 琀栀攀 唀⸀䬀⸀ 䈀漀洀戀 瀀爀漀樀攀挀琀Ⰰ 琀栀攀 洀漀猀琀 攀砀瀀攀爀椀攀渀挀攀搀 眀攀爀攀 渀漀琀 䈀爀椀琀椀猀栀 挀椀琀椀稀攀渀猀Ⰰ 猀漀 渀漀渀攀 挀漀甀氀搀 戀攀 最椀瘀攀渀 愀挀挀攀猀猀 琀漀 琀栀攀 戀椀最 瀀椀挀琀甀爀攀㬀 琀栀甀猀 䌀栀愀搀眀椀挀欀 愀氀漀渀攀Ⰰ 椀渀 猀瀀爀椀渀最Ⰰ ㄀㤀㐀㄀Ⰰ 戀攀挀愀洀攀 琀栀攀 昀椀爀猀琀 瀀攀爀猀漀渀 眀椀琀栀 琀栀攀 戀甀爀搀攀渀 漀昀 欀渀漀眀椀渀最Ⰰ 愀猀 栀攀 瘀椀瘀椀搀氀礀 爀攀挀愀氀氀攀搀 搀攀挀愀搀攀猀 氀愀琀攀爀Ⰰ ⠀椀渀 愀 瀀愀猀猀愀最攀 漀昀琀攀渀 焀甀漀琀攀搀 椀渀 琀栀攀 氀椀琀攀爀愀琀甀爀攀 愀戀漀甀琀 琀栀攀 䈀漀洀戀Ⰰ 愀猀 洀漀瘀椀渀最 愀 瀀愀猀猀愀最攀 愀猀 愀渀礀 椀渀 琀栀攀 愀渀渀愀氀猀 漀昀 猀挀椀攀渀挀攀⤀ 琀栀愀琀 琀栀攀 栀甀洀愀渀 挀漀渀搀椀琀椀漀渀 栀愀搀 爀攀愀挀栀攀搀 愀 琀甀爀渀椀渀最 瀀漀椀渀琀㨀

਀ "I remember the spring of 1941 to this day. I realized then that a nuclear bomb was not only possible - it was inevitable. Sooner or later these ideas could not be peculiar to us. Everybody would think about them before long, and some country would put them to action. And I had nobody to talk to. You see, the chief people in the laboratory were Frisch and Rotblat. However high my opinion of them was, they were not citizens of this country, and the others were quite young boys. And there was nobody to talk to about it. I had many sleepless nights. But I did realize how very, very serious it could be. And I had then to start taking sleeping pills. It was the only remedy, I've never stopped since then. It's 28 years, and I don't think I've missed a single night in all those 28 years." ਀

After the U.S. economy geared up for war, the gap between U.S. and U.K. resources was such that the U.S. was the clear senior partner, particularly since, as Mc George Bundy puts it, "the British at the political level were slow in understanding the difficulties in their own program in the year that followed the great intellectual achievement of the MAUD Report." Thus the U.S. effort became dominant, and the Manhattan Project was launched and placed under the direction of U.S. General Leslie Groves. Chadwick was viewed by H.M. Secret Service to be the physicist most likely to be able to persuade Niels Bohr to flee Nazi-occupied Denmark, so a message from Chadwick was smuggled to Bohr, who was thus persuaded to escape to Britain in the fall of 1943, thereafter coming to the U.S. to work with Chadwick, who was first sent to the U.S. in September 1943 as head of the U.K. Mission of scientists contributing to the Bomb Project, and as technical advisor to the U.K. members of the Combined Policy Committee which directed the Project. (He would return to Britain to meet Bohr, just escaped from Denmark, in late September, and then return to the U.S. in November.) As the leading figure in the MAUD saga, sending Chadwick made sense, but he had zero experience in international diplomacy strictly-defined, much less preparation for dealing with such a formidable person as Groves in such a crucial context as the Manhattan Project, the largest international scientific undertaking ever. His challenge was all the greater because of the decline in Anglo-U.S. relations after Britain had spurned the 1941 post-MAUD U.S. proposal for a joint Bomb Project; he would prove to be almost totally responsible for a startling improvement in this situation. ਀⸀⸀⸀⸀ 䌀栀愀搀眀椀挀欀 愀渀搀 眀椀昀攀 猀攀琀 甀瀀 爀攀猀椀搀攀渀挀攀 椀渀 䰀漀猀 䄀氀愀洀漀猀 椀渀 䨀愀渀甀愀爀礀 ㄀㤀㐀㐀Ⰰ 椀渀 愀 氀愀爀最攀 氀漀最 挀愀戀椀渀Ⰰ ⠀漀渀攀 漀昀 琀栀攀 昀攀眀 眀椀琀栀 戀愀琀栀琀甀戀猀⤀ 挀栀漀猀攀渀 昀漀爀 琀栀攀洀 戀礀 䜀爀漀瘀攀猀㬀 琀栀攀 搀愀甀最栀琀攀爀猀 愀爀爀椀瘀攀搀 昀爀漀洀 䌀愀渀愀搀愀 椀渀 攀愀爀氀礀 猀甀洀洀攀爀⸀ 䜀攀渀攀爀愀氀氀礀Ⰰ 䌀栀愀搀眀椀挀欀 猀瀀攀渀琀 洀漀猀琀 漀昀 栀椀猀 琀椀洀攀 椀渀 圀愀猀栀椀渀最琀漀渀Ⰰ 䐀⸀䌀⸀Ⰰ 愀渀搀 漀琀栀攀爀 瀀氀愀挀攀猀 眀栀攀爀攀 唀⸀匀⸀ 昀愀挀椀氀椀琀椀攀猀 愀渀搀 洀攀攀琀椀渀最猀 眀攀爀攀 氀漀挀愀琀攀搀Ⰰ 椀渀挀氀甀搀椀渀最 椀渀 䌀栀椀挀愀最漀 愀渀搀 一攀眀 夀漀爀欀⸀ 䠀攀 栀愀搀 愀甀琀栀漀爀椀琀礀 漀瘀攀爀 愀氀氀 渀漀渀ⴀ䄀洀攀爀椀挀愀渀 瀀栀礀猀椀挀椀猀琀猀 椀渀 琀栀攀 倀爀漀樀攀挀琀Ⰰ ⠀攀砀挀攀瀀琀 䈀漀栀爀⤀ 愀氀氀 漀昀 眀栀漀洀 眀攀爀攀 搀攀猀瀀攀爀愀琀攀氀礀 渀攀攀搀攀搀Ⰰ 戀攀挀愀甀猀攀Ⰰ 愀猀 䜀爀漀瘀攀猀 瀀甀琀 椀琀Ⰰ 琀栀攀 猀洀愀氀氀 渀甀洀戀攀爀 漀昀 焀甀愀氀椀昀椀攀搀 攀砀瀀攀爀椀洀攀渀琀愀氀 瀀栀礀猀椀挀椀猀琀猀 椀渀 琀栀攀 唀⸀匀⸀ 洀攀愀渀琀 琀栀愀琀 ∀眀攀 挀漀甀氀搀 渀漀琀 愀昀昀漀爀搀 渀漀琀 琀漀 甀猀攀 攀瘀攀爀礀漀渀攀 瀀漀猀猀椀戀氀攀⸀∀ 䤀琀 眀愀猀 䌀栀愀搀眀椀挀欀✀猀 樀漀戀 琀漀 瀀攀爀猀甀愀搀攀 琀栀攀洀 琀漀 攀渀搀甀爀攀 䜀爀漀瘀攀猀✀ ∀搀椀挀琀愀琀漀爀椀愀氀∀ 爀甀猀栀 琀漀 戀甀椀氀搀 愀 戀漀洀戀 愀琀 愀氀氀 挀漀猀琀猀Ⰰ 眀椀琀栀 渀漀渀攀 漀昀 琀栀攀 氀攀愀欀猀 漀昀 瀀爀漀樀攀挀琀 猀攀挀爀攀琀猀 猀漀 昀攀愀爀攀搀 戀礀 䜀爀漀瘀攀猀㬀 䌀栀愀搀眀椀挀欀✀猀 猀琀愀琀甀爀攀 愀猀 愀 一漀戀攀氀 氀愀甀爀攀愀琀攀 眀愀猀 椀渀搀椀猀瀀攀渀猀愀戀氀攀 昀漀爀 琀栀椀猀 琀愀猀欀⸀ 䠀椀猀 攀砀瀀攀爀琀椀猀攀 愀渀搀 愀瀀漀氀椀琀椀挀愀氀 戀攀渀琀 眀漀渀 䜀爀漀瘀攀猀✀ 挀漀渀昀椀搀攀渀挀攀Ⰰ 愀渀搀 䜀爀漀瘀攀猀 挀漀渀挀氀甀搀攀搀 琀栀愀琀 䌀栀愀搀眀椀挀欀✀猀 爀攀瀀漀爀琀猀 昀爀漀洀 䰀漀猀 䄀氀愀洀漀猀 眀漀甀氀搀 戀攀 洀漀爀攀 爀攀氀椀愀戀氀攀 琀栀愀渀 琀栀漀猀攀 瀀爀攀猀攀渀琀攀搀 戀礀 氀攀昀琀椀猀琀猀 氀椀欀攀 伀瀀瀀攀渀栀攀椀洀攀爀㬀 栀椀猀 氀漀礀愀氀琀礀 渀漀琀 椀渀 焀甀攀猀琀椀漀渀Ⰰ 䌀栀愀搀眀椀挀欀 挀漀甀氀搀 瀀攀爀猀甀愀搀攀 䜀爀漀瘀攀猀 琀漀 洀漀搀椀昀礀 栀椀猀 琀椀最栀琀ⴀ猀攀挀甀爀椀琀礀 瀀漀氀椀挀礀 猀漀洀攀眀栀愀琀Ⰰ 瀀愀爀琀椀挀甀氀愀爀氀礀 愀猀 琀漀 䜀爀漀瘀攀猀✀ 搀攀猀椀爀攀 琀漀 椀猀漀氀愀琀攀 瀀栀礀猀椀挀椀猀琀猀 昀爀漀洀 攀渀最椀渀攀攀爀猀⸀ 伀渀氀礀 䜀爀漀瘀攀猀Ⰰ 栀椀猀 䄀洀攀爀椀挀愀渀 猀挀椀攀渀琀椀昀椀挀 愀搀瘀椀猀漀爀Ⰰ ⠀渀漀琀 愀 一漀戀攀氀 氀愀甀爀攀愀琀攀⤀ 愀渀搀 䌀栀愀搀眀椀挀欀 眀漀甀氀搀 戀攀 瀀爀椀瘀礀 琀漀 愀渀 漀瘀攀爀愀氀氀 瀀攀爀猀瀀攀挀琀椀瘀攀 漀昀 琀栀攀 瀀爀漀樀攀挀琀Ⰰ 愀渀搀 琀栀甀猀 漀昀 椀琀猀 瘀愀爀椀漀甀猀 昀愀挀椀氀椀琀椀攀猀 愀挀爀漀猀猀 琀栀攀 唀⸀匀⸀ 䘀甀爀琀栀攀爀洀漀爀攀Ⰰ 愀猀 䜀爀漀瘀攀猀 氀愀琀攀爀 瀀甀琀 椀琀Ⰰ ∀椀昀 䐀爀⸀ 䌀栀愀搀眀椀挀欀 栀愀搀 戀攀攀渀 椀渀 挀栀愀爀最攀 漀昀 琀栀攀 䈀爀椀琀椀猀栀 洀椀猀猀椀漀渀 愀琀 琀栀愀琀 琀椀洀攀 嬀漀昀 刀攀搀 猀瀀礀 䬀氀愀甀猀 䘀甀挀栀猀✀ 樀漀椀渀椀渀最 琀栀攀 洀椀猀猀椀漀渀崀⸀⸀⸀䤀 愀洀 猀甀爀攀 琀栀愀琀 渀漀 猀甀挀栀 搀攀挀攀瀀琀椀漀渀 嬀戀礀 䘀甀挀栀猀崀 眀漀甀氀搀 栀愀瘀攀 戀攀攀渀 愀琀琀攀洀瀀琀攀搀⸀∀ 匀甀挀栀 眀愀猀 䜀爀漀瘀攀猀✀ 琀爀甀猀琀 椀渀 䌀栀愀搀眀椀挀欀 琀栀愀琀 匀椀爀 䨀愀洀攀猀 眀漀甀氀搀 琀栀攀爀攀愀昀琀攀爀 戀攀 戀礀 昀愀爀 䜀爀漀瘀攀猀✀ 挀氀漀猀攀猀琀 昀爀椀攀渀搀 愀洀漀渀最 琀栀攀 猀挀椀攀渀琀椀猀琀猀㬀 琀漀 䜀爀漀瘀攀猀Ⰰ 䌀栀愀搀眀椀挀欀 眀愀猀 ∀眀栀漀氀氀礀 猀琀爀愀椀最栀琀昀漀爀眀愀爀搀 愀渀搀 栀漀渀攀猀琀⸀⸀⸀愀 琀爀甀攀 最攀渀琀氀攀洀愀渀⸀∀ 吀栀椀猀 挀漀渀昀椀搀攀渀挀攀 椀渀 䌀栀愀搀眀椀挀欀 眀漀甀氀搀 爀攀猀甀氀琀 椀渀 栀椀猀 猀眀愀礀 挀漀洀椀渀最 琀漀 瀀攀爀琀愀椀渀 琀漀Ⰰ 渀漀琀 樀甀猀琀 琀栀攀 昀漀爀攀椀最渀攀爀猀Ⰰ 戀甀琀 愀氀洀漀猀琀 琀栀攀 攀渀琀椀爀攀 瀀爀漀樀攀挀琀㬀 漀渀攀 猀琀甀搀攀渀琀 漀昀 琀栀攀 洀愀琀琀攀爀 ⠀椀渀 愀 爀攀瘀椀攀眀 漀昀 䈀爀漀眀渀✀猀 戀椀漀最爀愀瀀栀礀 漀昀 䌀栀愀搀眀椀挀欀⤀ 挀愀氀氀猀 栀椀洀 ∀䜀爀漀瘀攀猀✀ 瘀椀挀攀爀漀礀 愀洀漀渀最 琀栀攀 猀挀椀攀渀琀椀猀琀猀⸀∀ 䌀栀愀搀眀椀挀欀✀猀 愀渀搀 䜀爀漀瘀攀猀✀ 昀爀椀攀渀搀猀栀椀瀀 眀漀甀氀搀 戀攀 氀椀昀攀琀椀洀攀⸀  .... To his scientific expertise he had to add diplomatic finesse, as when he managed to persuade his own government and French physicists of the error of their disputing Groves' veto of these physicists' wish to visit their homeland after the Liberation; the big secret did not leak to Hitler, and Chadwick got to see "his neutron" in action in the successful bomb test at Los Alamos. As described by William Lawrence, New York Times ace reporter, "Never before in history had any man lived to see his own discovery materialize itself with such telling effect on the destiny of man ..." Churchill, in his 6 August 1945 statement issued just after Hiroshima was devastated, would assess U.S.- British collaboration as follows:਀⸀㰀⼀瀀㸀㰀瀀㸀 The smoothness with which the arrangements for cooperation which were made in 1943 have been carried into effect ... reflects great credit on all concerned - on the members of the Combined Policy Committee which we set up; on the enthusiasm with which our scientists and technicians gave of their best - particularly Sir James Chadwick who gave up his work at Liverpool to serve as technical advisor to the United Kingdom members of the Policy Committee and spared no effort ... ਀㰀⼀瀀㸀㰀瀀㸀 U.S. writer Stephane Groeff's 1967 book Manhattan Project (sponsored by Reader's Digest) would assert that "the contribution of the British mission was inestimable." ਀⸀ 㰀⼀瀀㸀㰀瀀㸀 .....................................................

Chadwick preferred obscurity to glory, and refrained from public statements on the politics of the bomb; he held that such debates were for the public, not scientists, to dominate. However, after retiring, he did participate in interesting ways: in 1961 Pope John XXIII named him to join fifty-five others as a member of the Pontifical Academy of Science; this did not prevent Chadwick from joining 80 other Nobel Laureates' 1965 petition to the Vatican against the Pope's opposition to birth control.਀⸀⸀⸀⸀ 䌀栀愀搀眀椀挀欀 挀愀渀 戀攀 猀愀椀搀 琀漀 栀愀瘀攀 戀攀攀渀 琀栀攀 昀椀爀猀琀Ⰰ 愀渀搀 最爀攀愀琀攀猀琀Ⰰ 猀挀椀攀渀琀椀猀琀ⴀ搀椀瀀氀漀洀愀琀 䈀攀昀漀爀攀 䌀栀愀搀眀椀挀欀Ⰰ 猀挀椀攀渀挀攀 愀渀搀 猀琀愀琀攀挀爀愀昀琀 眀攀爀攀 愀氀洀漀猀琀 挀漀洀瀀氀攀琀攀氀礀 猀攀瀀愀爀愀琀攀 爀攀愀氀洀猀㬀 愀昀琀攀爀 䌀栀愀搀眀椀挀欀✀猀 洀椀猀猀椀漀渀 琀漀 琀栀攀 唀⸀匀⸀Ⰰ 猀挀椀攀渀琀椀猀琀猀 眀漀甀氀搀 爀攀最甀氀愀爀氀礀 戀攀 愀琀琀愀挀栀攀搀 琀漀 搀椀瀀氀漀洀愀琀椀挀 搀攀氀攀最愀琀椀漀渀猀 椀渀 愀氀氀 挀漀渀昀攀爀攀渀挀攀猀 ⠀攀猀瀀⸀ 猀甀洀洀椀琀 洀攀攀琀椀渀最猀⤀ 漀昀 爀攀愀氀 椀渀琀攀爀渀愀琀椀漀渀愀氀 椀洀瀀漀爀琀愀渀挀攀⸀ 吀栀愀琀 栀椀猀 爀漀氀攀 栀愀猀 戀攀攀渀 猀漀 漀戀猀挀甀爀攀搀 椀猀 挀氀攀愀爀氀礀 搀甀攀 琀漀 琀栀攀 昀愀挀琀 琀栀愀琀 栀椀猀 瀀攀爀猀漀渀愀氀 猀琀礀氀攀 眀愀猀 猀漀 漀瀀瀀漀猀椀琀攀 琀漀 琀栀攀 猀琀礀氀攀猀 漀昀 䔀椀渀猀琀攀椀渀 愀渀搀 伀瀀瀀攀渀栀攀椀洀攀爀Ⰰ 眀栀漀 攀渀樀漀礀椀渀最 琀栀攀 氀椀洀攀氀椀最栀琀㬀 䌀栀愀搀眀椀挀欀✀猀 爀攀瀀甀琀愀琀椀漀渀 眀椀琀栀 栀椀猀 挀漀氀氀攀愀最甀攀猀 昀漀爀 椀渀琀攀最爀椀琀礀Ⰰ 洀漀搀攀猀琀礀Ⰰ 猀栀礀渀攀猀猀 愀渀搀 猀琀椀昀昀渀攀猀猀Ⰰ 眀愀猀 瀀愀爀愀氀氀攀氀攀搀 戀礀 愀 搀椀猀琀愀渀琀 愀琀琀椀琀甀搀攀 琀漀眀愀爀搀 琀栀攀 洀攀搀椀愀Ⰰ 愀渀 愀琀琀椀琀甀搀攀 眀栀椀挀栀 愀氀洀漀猀琀 挀攀爀琀愀椀渀氀礀 栀攀氀瀀攀搀 攀渀搀攀愀爀 栀椀洀 琀漀 䜀攀渀⸀ 䜀爀漀瘀攀猀⸀

This discovery, while immediately seen to be important, has been particularly underrated from the standpoint of the significance of its timing, since subsequent history may have been quite different had the neutron been discovered even a year later than it was. The eventual invention of an A-bomb was inevitable, but its timing mattered greatly. Had the post-1932 breakthroughs in nuclear physics, such as the creation of the first chain reaction, been likewise delayed even a year, the A-bomb might have been ready for use, not in August 1945, but in August 1946, too late to have been used against Japan, which would probably have been conquered by then.

Without the memory of the horror of Hiroshima to deter war between the Soviets and the West, such a war probably would almost certainly have occurred, one way or the other, possibly with atomic weapons; the still-secret nature of this super-weapon (each superpower hiding Bomb-possession from the other until deciding to surprise the other with a devastating strike) would have had profound impact upon the strategic situation, with potentially fateful results. In the likely event that the U.S. finished building a Bomb before the Soviets, the U.S., in the event of war with the Soviets, would have faced a decision over Bomb-use even more momentous than that which Truman actually faced over Bomb-use against Japan, since he may or may not have been as confident of the lack of a Soviet retaliatory capacity as he actually was of the lack of a Japanese retaliatory capacity. At least the Soviets would have been less likely to miscalculate, had they produced a Bomb before the U.S. had revealed possession of such a device, in that their atomic capacity came (and would have come) partly from U.S. secrets delivered by pro-Soviet scientists working in the Manhattan Project almost from its inception; Soviet knowledge that the U.S. had a retaliatory capacity would likely have deterred the Soviets from striking first. In any case, such a war would have made the world a very different place than it is now.਀㰀⼀瀀㸀 ਀ ਀ ਀ ਀ ਀ James Chadwick was born in Cheshire, England, on 20th October, 1891, the son of John Joseph Chadwick and Anne Mary Knowles.
