ON 11 JANUARY 1939 after a visit to Berkeley, I wrote a letter to Ernest Lawrence that contained the following paragraph:
“I find it very difficult to thank you for the magnificent and instructive time which I had in Berkeley. It was truly fine of you to be so liberal of time and of thought on my behalf. I know of no laboratory in the world at the present time which has so fine a spirit or so grand a tradition of hard work. While there I seemed to feel again the spirit of the old Cavendish, and to find in you those qualities of a combined camaraderie and leadership which endeared Rutherford to all who worked with him. The essence of the Cavendish is now in Berkeley. I am sincere in this, and for these reasons I shall return again some day, and I hope very soon.”
