Oliphant met with the S-1 Section. Samuel K. Allison was a new committee member, an experimental physicist and a protégé of Compton at the University of Chicago. Oliphant "came to a meeting," Allison recalled, "and said 'bomb' in no uncertain terms. He told us we must concentrate every effort on the bomb and said we had no right to work on power plants or anything but the bomb. The bomb would cost 25 million dollars, he said, and Britain did not have the money or the manpower, so it was up to us."
