Albert Einstein was famously a pacifist, but he urged the US to develop the atomic bomb. Szilard and two other Hungarian physicists, Edward Teller and Eugene Wigner, who were both refugees, told Einstein of their grave concerns. Einstein and Leo Szilard reenacting the signing of their letter to Roosevelt warning that Germany may be building an atomic bomb. Einstein later said, "Had I known that the Germans would not succeed in developing an atomic bomb, I would have done nothing for the bomb." UK Prime Minister Winston Churchill meets with Roosevelt in the meeting where they finalized plans for an atomic bomb.
