The Atomic Bomb: Albert Einstein's Letter to President Franklin D. Roosevelt
Digital History ID 1184
Author: Albert Einstein
Date:1939
Annotation: In August 1939, six months after physicists Otto Hahn and Fritz Strassman had demonstrated the process of nuclear fission, Albert Einstein, at the urging of physicist Leo Szilard, wrote to President Franklin D. Roosevelt about the danger of Nazi Germany creating an atomic bomb.
Document: Sir:
Some recent work by E. Fermi and L. Szilard, which has been communicated to me in manuscript, leads me to expect that the element uranium may be turned into a new and important source of energy in the immediate future. Certain aspects of the situation which has arisen seem to call for watchfulness and, if necessary, quick action on the part of the Administration. I believe therefore that it is my duty to bring to your attention the following facts and recommendations:
In the course of the last four months it has been made probable-through the work of Joliot in France as well as Fermi and Szilard in America-that it may become possible to set up a nuclear chain reaction in a large mass of uranium, by which vast amount of power and large quantities of new r
