In London, Bertrand Russell published the Russell-Einstein Manifesto that expressed many scientists’ concerns regarding nuclear proliferation. It reads: “In view of the fact that in any future world war nuclear weapons will certainly be employed, and that such weapons threaten the continued existence of mankind, we urge the governments of the world to realize, and to acknowledge publicly, that their purpose cannot be furthered by a world war, and we urge them, consequently, to find peaceful means for the settlement of all matters of dispute between them.” In addition to Russell and Einstein, the document was signed by other famous scientists, among them Bridgeman, Infeld, Müller, Powell, and Yukawa.
