The Manhattan Project was one of the most secretive projects in the history of the United States. It took place during World War II and its purpose was to create a bomb by splitting atoms apart. This project was a success and created one of the most devastating bombs ever used by mankind, the atomic bomb. The president at the time, Harry S. Truman, had to face the many factors that were involved in making the decision to drop the bomb. In this paper I will discuss those and the events leading up to The Manhattan Project. The factors in dropping the bomb can be put into three categories: military, moral and political. I will also go into the scientific means of developing such a weapon.Albert Einstein was living in Germany at the time Hitler came into power. Albert Einstein, Edward Teller, Leo Szilard and the rest of his colleagues wrote a letter in August 1939 to warn the United States that Germany was researching and developing nuclear weapons. They were afraid that once Germany finished building the bomb, they would use it on the United States. (Cayton, Perry, Winkler, 1995, pg. 786)When President Franklin Delano Roosevelt received the letter, he was both amazed and scared. He was amazed that science could make such a devastating weapon, a weapon that could destroy an entire city. President Roosevelt then quickly assembled the Manhattan Project so they could build the bomb before Germany. The Manhattan Project started in 1942 in Oak Ridge, Tennessee. The name "Manhattan Project" was secretly coded as a United States effort in an attempt to build an atom bomb during World War II. It was named after the Manhattan Engineer District of the US Army Corps of Engineers, because most of the research was done in New York City. In Oak Ridge there were tests for separating a rare Uranium-235 (U-235) an unstable isotope from Uranium-238 (U-238).General Leslie Groves was chosen by President Roosevelt to lead the project.
