This article explains Niels Bohr’s conveyance of Lise Meitner's and Otto Frisch’s theory of nuclear fission to the United States in 1939. After reviewing the results of experiments conducted by Otto Hahn and Fritz Strassman, Frisch and Meitner theorized that the barium Hahn and Fritz had found after bombarding uranium with neutrons had been the result of splitting a small portion of atoms in the uranium sample. Frisch sought out Niels Bohr in Copenhagen and shared the conclusions that he and Meitner had drawn. The article discusses how Bohr worked out the theory, the transatlantic communication mishaps between Bohr and Frisch, and how Bohr introduced the theory of uranium fission to the physics community in the United States.
