I do not believe that America can be made secure by keeping ahead in such an arms race,” Szilard declared in April 1962 as he toured the country building support for the Council. “What one needs to create is not a membership organization, but a movement,” Szilard said.

Szilard fought for years to harness the power of atomic energy. In a letter prepared in 1939 for Albert Einstein, Szilard warned President Franklin Roosevelt about the possibility of atomic weaponry and urged the United States to develop these weapons before Nazi Germany could. This letter catalyzed the American government’s involvement in atomic research and led to the establishment of the Manhattan Project.

After unleashing the first controlled nuclear chain reaction and participating in the Manhattan Project, Szilard adamantly advocated against using the atomic bomb. Szilard drafted a July 1945 petition to President Harry Truman opposing the use of the bomb on moral grounds. Szilard also made a concerted effort to warn Truman about the dangers of using atomic weapons against Japan.
