On August 2, 1939, Albert Einstein signed one of the most consequential letters in history.
Drafted by physicist Leo Szilard, the letter warned President Franklin D. Roosevelt that Nazi Germany could be developing an atomic bomb using uranium. It urged the United States to accelerate its own nuclear research before it was too late.
Although Einstein did not write the letter himself, his signature gave it the influence needed to reach the White House. Roosevelt responded by creating the Advisory Committee on Uranium, a decision that eventually led to the Manhattan Project and the development of the first atomic weapons.
A single letter helped alter the course of World War II and forever changed the future of science, warfare, and global politics.
