Letter from Albert Einstein and the Emergency Committee of Atomic Scientists

Not long after the end of World War II, Albert Einstein founded the Emergency Committee of Atomic Scientists. He and his co-founder, scientist Leό Szilάrd, toured the country to educate the public on the peaceful uses of nuclear energy. Ironically, an earlier letter signed by Einstein—warning President Roosevelt of the dangers of a possible German atomic bomb—is credited with starting the U.S. drive to establish the Manhattan Project that built the first atomic bomb.
