The Manhattan Project may have never come to fruition if it wasn’t for that one German physicist: Otto Hahn. Hahn, working with Fritz Strassmann, discovered that when uranium was bombarded with neutrons a radioactive barium isotope was among the products. Hahn immediately realized the importance of this and told one of his colleagues (who had fled Germany due to nazi racial laws), Lise Meitner, about his findings. Lise worked with her nephew Otto Frisch to replicate Hahn’s findings and conclude that fission had taken place. The duo immediately made their way to Copenhagen to tell Bohr of their theories. Bohr was soon to be in the United States at Princeton’s Institute for Advanced Study. (Hewlett and Anderson,
