[Q] And did you go speak to Oppenheimer when the time came to... what you should be doing in the future?

Yes, I talked with Oppenheimer and he said it was good that I go back to England. He thought that I should spread the word in England. I'd done all this good stuff in America, that I should go back to England and build a school in England and my future should be in England. He was very clear about that. He didn't want me to settle in the States. He wrote me a cryptic note which I was to give to the harbourmaster at Lowestoft in case of necessity, and that was the kind of obscure language he loved to use. I never really figured out what he meant, but I think the basic idea was that... and Niels Bohr in 1940... or whenever it was, I guess it was '43...

[Q] When he left...

...when the Germans - well, of course they had occupied Denmark for several years - but they were going to have a round up of all the Jews, and so he and his Jewish friends took the boat across to Sweden, and I think that was roughly what Oppenheimer had in his mind, that...

[Q] That you could always come back...

... that I could come back to Princeton, if I were in a desperate situation of that sort. But why he chose the harbourmaster at Lowestoft I never could figure out.
