A couple of prominent physicists wrote up a warning letter, had it signed by Albert Einstein, and had it delivered to US president Franklin D. Roosevelt, urgently warning of the potential development of a new type of extremely powerful bombs, in August of 1939.

In June of 1941, the Office of Scientific Research and Development was created by FDR's Executive Order 8807. They were authorized to engage in research and establish large engineering projects.

In October, FDR approved the atomic program and got in touch with England's Prime Minister Winston Churchill, recommending correspondence in matters atomic, and project sites were established in the US & Canada.
