Shortly before his intuition about an atomic bomb, Leo Szilard had been reading The World Set Free by H. G. Wells--a novel about a German invasion of France and the use of atomic bombs in a global war, a novel written in 1913 but set in the 21st century. Wells called his radioactive element Carolinum: "once its degenerative process had been induced, [Carolinum] continued a furious radiation of energy, and nothing could arrest it." In 1913, Wells was already writing about radioactive decay, half-lives, burning cities, even about deforestation, diminishing supplies of coal and oil, and the rush toward bankruptcy. And he inspired Szilard. Wells wrote--and Szilard read--of the final achievement of a world government and the abolition of atomic weapons--the "world set free." "The catastrophe of atomic bombs shook men...," Wells wrote, "out of their old-established habits of thought." And it was H.G. Wells who gave us the phrase, "a war to end all war."
