What developed then I do not know. I know the results, but how they could have come about I do not know. As Bethe and I left Oppenheimer's office, Bethe said to me- I am still planning to come to Los Alamos. You should be satisfied. And I was. Within a week I heard that he changed his mind: he was not coming. I believe that the situation implied, and I accepted the implication, that the work had to be done, and I better not run around and ask others to do it. I should take care of it as best I could myself. One of my not so close friends reacted differently - Johnny Wheeler, He and I had met as Rockefeller Fellows in Copenhagen. He worked with Bohr, showing some of the difficulties, the need to separate isotopes in order to get anywhere with the atomic bomb. He was in France on leave of absence, doing some special physics there that he enjoyed. I wrote to him, he wrote back- You seem to be alone doing that. I'd be delighted to come back. And did. Showed up in Los Alamos after we had started on the President's recommendation to do a little more and indeed, Bradbury's contribution was that he said- We have to work our own people harder. We shall work on Saturdays and I will raise everybody's salary by 20% for working six days a week rather than five. Johnny Wheeler arrived. We talked about it - well, I tried to talk about it - about the whole situation and Johnny was not talking, he was very, very sleepy. Next morning I saw him and then he said- Well, you know, Edward, when I went to sleep last night, there was a Bible next to my bed and I opened it and you know what I found? Six days shall thou labor. Well he did. He brought others who did and he was a very, very great help. In the meantime things were going on in Washington. I got an invitation from an important senator, Brian McBain. He was chairman of a committee that kept watch on the atomic developments.
