Einstein has some credit in the development of the nuclear bomb, but never thought of it himself... I believe it was Hitler who first thought of the atomic bomb. The Germans were working on a way to harness the energy from a split atom. Einstein sent the US president a letter, telling him of the power such a weapon could have, and the Germans were working on splitting atoms. That brought about the Manhattan Project.


The Einstein letter to FDR was actually entirely written by Leo Szilard, all Einstein did was sign it.

The writer H.G. Wells had imagined them and wrote about them in his 1914 novel "The World Set Free", but this was just SciFi.

Leo Szilard was the first to actually invent the process that makes the atomic bomb work (neutron chain reaction) in 1933 while in London and patented this on June 28, 1934.

A team of German scientists working in Germany and Sweden discovered fission in uranium-235 in 1939 and after the publication of their paper, Germany blocked further publication of the results of all research in nuclear physics.

By the time the Manhattan Project became fully active, Germany had already decided to scale back their nuclear project to just basic reactor research with the single goal of building power reactors after Germany won the war. They considered a bomb impractical in the time estimated to win the war by conventional means, even if it was possible (and Heisenberg's calculations suggested such a bomb would be too large for any available aircraft to deliver).

To Hitler the idea of an Atomic Bomb sounded like Jewish Physics, and thus nonsense. Hitler knew nothing of physics, nuclear or otherwise, and the teaching of Einstein's theories of relativity were already banned in Nazi Germany simply because Einstein was a Jew (implicitly making it Jewish Physics) regardless of any experimental evidence confirming the theories.

We developed the first working atomic bomb but, GER. made up the idea.

Albert Einstein sent a letter 2 the white house proposing his idea of the atomic bomb he created it

What gave you that idea? It isn't obsolete in any way. In fact every Hydrogen bomb contains an Atomic bomb as its primary stage.

well, the atomic bomb research was done by Robert oppenheimer. the original creation or idea was from albert Einstein

No Idea! But I heard they can survive an atomic bomb.

he took the idea of ernest rutherford's idea and tweaked them up a bit. in the end he creted the atomic bomb

Both atomic bombs dropped on Japan were successful. What gave you the idea they weren't?

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.

for some reason it was really great idea to drop the atomic bomb at japan why would they start the us. they knew tht thy couldnt stop or hanle the u s in the first place..

The president was Harry S. Truman

No he thought it was the best solution and would save millions of american lives, along with the lives of allied troops. He fully supported the idea of dropping the bomb fully.

We were trying to "open the Japanese eyes" to world issues... nevermind, I have no idea.

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).

Because even in the U.S. and Japan everyone hated the idea because an atomic bomb could kill everyone including children.

Leo Szilard. Einstein came up with the idea though, I think.

Physicists world wide knew about the possibility for atomic power and atomic blast. They knew about it long before the Manhattan Project developed atomic power and atomic bombs. It was Physicist Einstien who wrote a letter to FDR to let him know there was evidence of the Germans looking into the idea of building an atomic bomb.

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.

Franklin D Roosevelt did. He approved the atomic bomb idea.

Albert Einsten wrote him that Germany were working on the atomic bombs. The German scientists did all they could to take longer.

an American B-29 bomber dropped the world's first deployed atomic bomb over the Japanese city of Hiroshima.

To end the war and collapse Japan's means to make war ever again.

H. G. Wells thought of them and coined the term "atomic bomb" for his 1914 novel The World Set Free. However he had no idea how they might work.Leo Szilard invented the process of the neutron chain reaction in 1933 and patented it in 1934 with claims for its use in atomic bombs and reactors. However he had no idea what material(s) might be suitable to support the neutron chain reaction.The work of Otto Hahn and Fritz Strassmann, in Germany and Lise Meitner and Otto Robert Frisch, in Sweden showed in January 1939 that uranium fissioned when struck by neutrons. Thus it might be a suitable material for making atomic bombs.

About the time Leo Szilard told him about it and had Einstein sign the letter Szilard had written to FDR.

The atomic bomb was invented in 1933 by Leo Szilard, but could not be built until 1945.The hydrogen bomb was invented in 1943 during discussions of possible atomic bomb designs (but it was not recorded who proposed the idea, although Edward Teller became its main proponent), but could not be built until 1952.
