Writing in 1913, on the eve of World War I’s mass slaughter and long before World War II’s mushroom cloud finale, H. G. Wells imagined a war that begins in atomic apocalypse but ends in a utopia of enlightened world government. Set in the 1950s, Wells’s neglected novel The World Set Free describes a conflict so horrific that it actually is the war that ends war.

Wells—the first to imagine a “uranium-based bomb”—offers a prescient description of atomic warfare that renders cities unlivable for years: “Whole blocks of buildings were alight and burning fiercely, the trembling, ragged flames looking pale and ghastly and attenuated in comparison with the full-bodied crimson glare beyond.” Drawing on discoveries by physicists and chemists of the time, Wells foresees both a world powered by clean, plentiful atomic energy—and the destructive force of the neutron chain reaction.
