I remember a friend of mine who worked with me, Paul Olum, a mathematician, came up to me afterwards and said, ‘When they make a moving picture about this, they’ll have the guy coming back from Chicago to make his report to the Princeton men about the bomb. He’ll be wearing a suit and carrying a briefcase and so on—and here you’re in dirty shirtsleeves and just telling us all about it, in spite of its being such a serious and dramatic thing.’
