Albert Einstein and Leo Szilard sit at a garden table on the veranda of Einstein's house in Princeton, working together on the wording of the letter to President Franklin D. Roosevelt; Szilard holds a notebook while written pages, an inkwell and fountain pens lie on the table. The letter warned of the possibility of a German atomic weapon and recommended government support for American uranium research. Szilard, who had theoretically predicted the nuclear chain reaction, remained a driving but also critical voice throughout the Manhattan Project; in 1945 he initiated a petition against using the bomb on Japan.
