Winner of the 1935 Nobel Prize in Physics, he discovered the neutron for the atomic bomb. ALS signed “J. Chadwick,” one page both sides, 5.5 x 7, July 24, 1968. In part: “I am not able to answer properly your question ‘How did I feel when I received the Nobel Prize?’ I suppose that you mean when I received the news that a Nobel Prize had been awarded to me. Naturally, I was delighted to receive such a signal honour, but to say this does not adequately describe the variety of emotions which I experienced. This event happened in 1935, now a long time ago; and I no longer remember how the news reached me. But I still remember the telephone call from my old master and friend, Lord Rutherford, sending his congratulations and expressing his pleasure; this was in itself a Nobel Prize.” In fine condition, with show-through of handwriting on opposing sides. An insightful and personal look at Chadwick’s grand recognition. RRAuction COA.
