The Manhattan Project, or more formally, the Manhattan Engineering District (MED), was the effort during World War II to develop the first nuclear weapons of the United States with assistance from the United Kingdom and Canada. Its research was directed by American physicist J. Robert Oppenheimer, under the overall project supervision of General Leslie R. Groves and the auspices of the U.S. Army Corps of Engineers. The project's origins were in fears during the 1930s that Nazi Germany was also investigating such weapons of its own.

"This new phenomenon would also lead to the construction of bombs,
The Manhattan Project was started to develop and build atom bombs. At the time it was believed that Germany and Japan were working on them because in the late 1930's it became known among phycisists that it might be possible. Albert Einstein used his influence to get the government to examine the possibility and start the program, but otherwise he had almost no part in it.
He encouraged FDR to start the Manhattan Project because the Nazi Germans were starting to focus their interest into nuclear physics, and had recently split the atom. Making the US build an atomic bomb would make them a step ahead of all their enemies, but has also led to other countries being eager to have it also (the arms race), and welcome to the Cold War.

He was warned in the Einstein-Szilard letter of 1939 that Nazi Germany was probably already working on atomic bombs and the damage they could do.
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.

Oppenheimer as Einstein was not directly involved in the Manhattan Project he only supported it initially and encouraged Roosevelt to proceed in a letter.
The atomic bomb was developed by the Manhattan Project led by Robert Oppenheimer. What Einstein did was to write to the President. He and several other scientists told Roosevelt of efforts in Nazi Germany to purify uranium-235, which could be used to build an atomic bomb. The President put the plans in work to build the bomb.
On August 2, 1939, just before the beginning of World War II, Albert Einstein wrote to then President Franklin D. Roosevelt. Einstein and several other scientists told Roosevelt of efforts in Nazi Germany to purify uranium-235, which could be used to build an atomic bomb. It was shortly thereafter that the United States Government began the serious undertaking known then only as "The Manhattan Project." Simply put, the Manhattan Project was committed to expediting research that would produce a viable atomic bomb. Yes, I believe they used it in 1945 July 16.
I think it started by a letter of concern from Albert Einstein to President Franklin Roosevelt.
Einstein didn't precisely participate in the making of the atomic bomb. all he did was sign a letter to president Franklin Roosevelt to encourage the making of it =-]
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.
Franklin Delano Roosevelt
Albert Einstein did not work on the Manhattan Project, the US efforts to develop the atomic bomb. He was denied sufficient security clearance to do so. He did however write a letter to President Roosevelt, composed by his friend Leo Szilard, who did work on the project. Einstein was a teacher.
write a letter warning him about an atomic bomb
Albert Einstein.
he knew that the germans were making an atomic bomb.
No he did not create the atomic bomb nor was he involved with the Manhattan Project. He did play a role though by sending a letter to convince president Roosevelt to start work on a nuclear weapon, and many of his theories went into the making of it. Einstein himself was a pacifist and regretted for the rest of his life that he had influenced the creation of nuclear weapons.
President Franklin D. Roosevelt
the letter inspired nuclear fusion.
