About the time Leo Szilard told him about it and had Einstein sign the letter Szilard had written to FDR.
well, the atomic bomb research was done by Robert oppenheimer. the original creation or idea was from albert Einstein
Franklin Delano Roosevelt
No.
Leo Szilard. Einstein came up with the idea though, I think.
he had the idea of the atomic bomb and thought the German army had more Info than USA about bombs. Roosevelt wanted to bomb Japan, then Einstein begged him in a letter not to because Germany didnt have as much info as he thought. Roosevelt died and Truman decided to finally drop the two atomic bombs on hiroshima and nagasaki.
Nobody.It was Leo Szilard, a Hungarian who had invented the Atomic Bomb in 1933 while living in London that wrote a letter to FDR about the risk if the Nazis built the atomic bomb first, then had Einstein sign it. The Szilard-Einstein letter eventually started the Manhattan Project.
None of the men involved with making "the bomb" were happy about it. They, more than any other living human being knew what doors they had opened (the atomic age).
Truman didn't. Albert Einstein did, and after seeing the horrors it caused, stated he wished he had never made the atomic bomb.----------------------------------------------------------------------------------------------------------------------------------Neither did, it was made by the Manhattan Project which involved tens of thousands of scientists, technicians, and ordinary workers many of which had no idea what was being made. FDR authorized the project, at the request of Leo Szilard on a letter signed by Einstein (which was the only connection Einstein had to it, he was a pacifist and never worked on anything war related).

Albert Einstein's only connection to nuclear weapons was to sign a letter written by Leo Szilard in 1939 that was addressed to president Franklin Roosevelt warning that Nazi Germany might be working on an atomic bomb and that the US should begin research into the subject. Einstein was a pacifist and refused to do any war or weapons related work, he spent all of World War 2 working on the equations of his Grand Unified Theory (which he never worked out by the time he died). Albert Einstein had no idea if any action had been taken on the letter he had signed until he saw the August 6, 1945 newspaper headlines reporting the atomic bombing of Hiroshima.
Albert Einstein's work in theoretical physics, particularly his theory of relativity, revolutionized our understanding of time, space, and gravity. His discoveries laid the foundation for numerous technological advancements and fundamentally altered the way we perceive the universe. Additionally, Einstein's advocacy for peace and social justice continue to inspire efforts for a more equitable and compassionate society.
