Probably the most central was Leo Szilard. He drafted a letter that was signed by Einstein warning Roosevelt of the possibility that the Germans were working on atomic weapons, which was directly responsible for the US Manhattan Project.
No, Einstein had very little to do with the design of any nuclear weapon beyond signing a letter written by Szilard to FDR that warned that the Germans were likely working on such a bomb and if they were we better get there first.
V-E day
The conception and the development of the atomic bombs were started in 1942 when Einstein contacted Roosevelt to warn him the Germans were dabbling in atomic bomb ideas. It was completely manufactured and ready to drop in 1945.
It was president Franklin D. Roosevelt who order the development of the atomic bomb. It was Harry S. Truman who order its use on Japan during World War II.
The concept of the atomic bomb was originally conceived by physic scientists in many countries. Once Einstein learn the Germans were researching and attempting to build an atomic bomb he contacted President Roosevelt. Roosevelt and the War Cabinet chose to develop their own in the Manhattan Project. They managed to develop three bombs. One was used in testing and the other two were dropped on Japan. They did not invent the bombs but they were the first to use them. As I said before it was invented the minds of the theorists.
Albert Einstein warned President Franklin D. Roosevelt about the potential development of an atomic bomb by the Germans during World War II, which led to the initiation of the Manhattan Project in the United States.
He warned President Roosevelt that he believed Germany was developing an atomic bomb, so the United States should do so as well.
Franklin Roosevelt- but he died before the atomic bomb was used. Harry Truman was the next president, and ordered the use of the atomic bomb.
Wanted to developer the atomic bomb before Germans
No, Albert Einstein did not develop the atomic bomb, which was developed by a team of researchers led by J. Robert Oppenheimer. Einstein's theoretical work does provide the basis upon which the bomb was developed.
write a letter warning him about an atomic bomb
Albert Einstein.
No. He died prior to the testing of the atomic bomb. Harry S Truman was President.
President Theodore Roosevelt Harry S. Truman, the "buck stops here" president.
He and himself only.
he knew that the germans were making an atomic bomb.
Franklin Delano Roosevelt
