The one man who really wouldn't give up was, of course, Leó Szilárd. He, together with Eugene Wigner, went to Einstein, whom they knew way back from Berlin and they put the case before Einstein and asked him to use his authority. I don't know to what extent Einstein then agreed, but I know of first hand- first hand about it - was concerning Szilárd and concerning the point that Szilárd, with all his ingenuity, still did not know how to do one thing. He did not know how to drive a car. And so he asked, where I was teaching then summer school at Columbia, summer of '39, the 2nd of August, I think, to be precise, to drive me out, to drive- drive him out to the end of Long Island where Einstein spent his summer weeks. And I did drive, we didn't get into any trouble. We couldn't find Einstein, for the simple reason that Szilárd did not know where he lived, he only knew the name of the place. So we asked and finally we came down to a nice little girl, I don't think she was ten years old yet. She hadn't heard ever about Einstein either but then Szilárd said- This nice old man with the long white hair. - Oh yes, right there, next door. So we arrived. And Einstein invited Szilárd for tea and since he was very democratic he invited Szilárd's chauffeur as well. So I was there on the historic occasion when Szilárd took out the letter of Einstein to Roosevelt, from Szilárd's pocket - I think Szilárd's writing - informing the President of the possibility of an atomic bomb, of the real danger that the Nazis might do something about it. Szilárd gave the letter to Einstein and Einstein read it carefully. And my impression is that he read it- that he never had seen it before. At any rate, when he was through reading it, he said- Yes, yes. This would be the first time that nuclear energy would be re- would be released closer to us than in the sun. And he signed.
