The Manhattan Project
What was the Manhattan Project, we know it created the first atomic bombs (see Fig. 1), but how did it end World War II and use fission to its full power? World War II and the Manhattan Project lasted from 1939 to 1945. World War II started when Hitler invaded Poland on September 1, 1939. The origins of the Manhattan Project date back to a letter Albert Einstein sent Franklin D. Roosevelt warning him of the powers of fission and the weapons it could produce. 60 million people were killed in World War II and the Manhattan Project resulted in the deaths of 130,000 Japanese civilians.

Enrico Fermi, Arthur Holly Compton, Ernest Lawrence, Richard Feynman, Leo Szilard, Harold Urey, J. Robert Oppenheimer, and Leslie R. Groves were all committed to the Manhattan Project. There were roughly 100,000 people that took part in the building of the atomic bomb. In 1940 German scientists began conducting similar research that was taking place in the Manhattan Project. To hasten progress and prevent the Germans from being the first to produce atomic bombs, Urey and Pengram were sent to England in the fall of 1941 where they made the first steps in making the Manhattan Project an international effort. Two years later the U.S., Great Britain, and Canada had created combined policy committee. This collaborative effort caused many scientists from Canada and Great Britain to the United States, where it would be easier for them to work on the Manhattan …show more content…
The project was also in need of a strong leader, Leslie R. Groves was selected by the U.S. secretary of war, George Marshall. Groves was a colonel in thee Army Corps of Engineers, even though he was a strong leader who would often “bully his way into getting what he needed”(Elish, 19) a brilliant mind that expertised in science was needed to help Groves. Intellectual and physicist J. Robert Oppenheimer was selected by Groves Enrico Fermi had developed a system that could create a fission chain reaction. Upon learning about the system the U.S. government budgeted $40,000 to construct Fermi’s system. This system was of high importance and allowed scientists to use the power of atomic bombs. This fission process required uranium and graphite to work properly. Fermi and other scientists chose a squash field located beneath Stagg Field at the University of Chicago to set off a chain reaction. On December 2, 1942 Fermi and other scientists, using uranium, successfully produced and controlled a chain reaction self-sustained by
Then he went to teach at Berkley University.4 Another main person in the research project was Enrico Fermi. Fermi was a graduate of the University of Pisa, where he received his Ph.D. Fermi then went to the University of Rome teaching chemistry and biology. Fermi played a major role in the development of the bomb by creating a sustained nuclear fission chain reaction, which was critical to making the atomic bomb.4 Richard Feyman was another scientist which worked on the atomic bomb. Feyman graduated from Princeton where he excelled in physics and other scientific studies. Feyman's big duty on the Manhattan Project was to break big problems into smaller easier to do problems.4 The Manhattan Project, also had to have facilities for the research and testing of the atomic bomb. Some of the facilities built by U.S. Army Corps of Engineers included: power stations, factories, steel works, hospitals, laboratories, and housing for everybody that worked on the project.. Other facilities that were built for the construction of the bomb were plants to make the radioactive material needed to construct the bomb. Oak Ridge, Tennessee was used to make uranium which was used as an explosive to react with plutonium. The plutonium itself was made in Hanford, Washington.5 To make this explosion possible, a piece of uranium was fired at another piece of uranium to make the critical mass that was needed for an explosion. Critical mass is the exact amount of
The Manhattan Project was created out of the fear of their current enemy, Germany of making the first atomic bomb and using it in the war. The current President of the United States was Franklin Roosevelt. It was seen that Germany was making great advances in the war which worried many. But the people who were very worried were three prestigious scientists. Leo Szilard, Eugene Wigner, and Edward Teller who were Hungarian scientists who immigrated to the United States during the war. Szilard and the other scientists wished to advocate for the start of a program that put all efforts into making an atomic bomb. But of course they were very intelligent on how to get their cause across seriously. “Though the three men, particularly Szilard, were well known
Even before the outbreak of War, the United States was concerned with a fascist regime in Europe researching in nuclear weapons. In retaliation, the United States began to fund an atomic weapon development program which became known as “The Manhattan Project” led by J. Robert Oppenheimer. Over the next several years, the Manhattan project started obtaining key materials such as Uranium-235 and Plutonium and testing prototypes until they reached a working model (Coroner).
Thesis Statement: The Manhattan Project was the American program for researching and developing the first atomic bombs because of the project it cost a lot of people their lives.
Leo Szilard was a Hungarian Physicist who dedicated himself to learning how to create a successful chain reaction to make an atomic bomb before the Germans had a chance to do so. Szilard convinced Albert Einstein to help research with him on how to create an atomic bomb. The “Einstein-Szilard” letter, sent to President Franklin D. Roosevelt led to the foundation of research into nuclear fission by the United States government. This ultimately encouraged the development of the program, the Manhattan Project.
The process of building the two atomic bombs was long and hard. The Manhattan project employed 120,000 people, and cost almost $2 billion. Although there were 120,000 Americans working on the project only a select group of scientist knew of the atomic bomb development. Vice president Truman never knew about the development of the bombs until he became president. The axis powers did not know what was going on with the development of the atomic bomb; there was a soviet spy in the project. The soviet spy was Klaus Fuchs, and he had become one of the few people who knew of the bombs.
The Manhattan project was an organization that was formed to make mass weapons of war. It was formed in fear of the Germans, and we used the project to make first atomic bomb. The first atomic was done “under the direction of theoretical physicist J. Robert Oppenheimer.” His research “ushered in the atomic age”, and his group helped us make the first atomic bombs
Throughout the Roosevelt administration and later through the Truman administration, it became clear that both had the distinct focus of ending World War II at the earliest possible time. This is a common theme identified throughout J. Samuel Walker’s Prompt and Utter Destruction. While some countries had put moderate effort into researching atomic power and how it could affect the war, the United States was the only country capable of putting full effort into researching and creating an atomic bomb that could be utilized during the war. Following warnings from scientists that informed Roosevelt of the possibility of the Germans making progress on their knowledge of nuclear energy, Roosevelt assigned a lofty and difficult project to the U.S. Army Corps of Engineers. This project soon became known as “the Manhattan Project” due to the engineer district that was formed to design and build this bomb being originally headquartered in New York. The Manhattan Project was established at a time in the war when the United States was uncertain of its outcome. After the first successful, self-sustaining nuclear chain reaction took place in a squash court at the University of Chicago, the idea of an atomic bomb became more feasible. However, while the idea became more feasible, the transition from experimental knowledge to designing an actual bomb was a huge step that involved many uncertainties and troubles. Although the Manhattan Project was formed during a period of uncertainty, the government had high hopes of the newly formed project, but despite these high hopes, the Manhattan Project faced seemingly insurmountable obstacles as it moved from experimental knowledge to designing the bomb, the most prominent being the design for the new technology and the role the bomb would play in the realm of global diplomacy.
The origins of the Manhattan Project go back to 1939, when Hungarian-born physicist Leo Szilard, who had moved to the U.S. in 1938 to conduct research at Columbia University, became convinced of the feasibility of using nuclear chain reactions to create new, powerful bombs. German scientists had just conducted a successful nuclear fission experiment, and based on those results, Szilard was able to demonstrate that uranium was capable of producing a nuclear chain reaction. Szilard noted that Germany
In 1942, the Manhattan project was started. The Manhattan project was created to make the first nuclear weapon in the United States.The bomb was created to help defend the United States. World War II was going on and the United States was not involved yet. President Harry S. Truman was elected after the death of Franklin Delano Roosevelt. Harry
The Manhattan Project was assembled when “in 1939 the world’s scientific community discovered that German physicists had learned the secrets of splitting a uranium atom.” (US History 1) This caused many people to panic and it was later agreed that this issue of the Axis powers developing nuclear weaponry should be brought up to the United States, which could perhaps stop the Germans from causing unspeakable destruction to much of the world. Scientists Albert Einstein and Enrico Fermi, who both were living in the United States after leaving their previous countries to escape from either persecution or just leave the fascist state that Italy was currently in. Fermi was the scientist that went to Washington in order to express his concerns about this development of the splitting of the uranium atoms but not many others shared his concerns. Once Fermi
Groves was appointed to supervise every aspect of the atomic bomb. It was called the “Manhattan Project”, and was conducted in the utmost secrecy. On March 15th, 1945 at the request of General Leslie Groves, Americans dropped nearly 1,300 tons of high explosive bombs on the German thorium ore processing plant at Oranienburg. The above-ground parts of the plant were destroyed and Germans had to stop atomic bomb research.
The Manhattan Project was to see if making an atomic bomb possible. The success of this project would forever change the world forever making it known that something this powerful can be manmade. The Manhattan Project’s success was something that had an impact on everybody involved since they helped create something with so much destructive power it could destroy a city within seconds.
The ingredients that went into baking the cake. The United States government initiated the Manhattan Project, when they were notified by a letter from Albert Einstein, which disclosed the prospects of a nuclear chain reaction to formulate a nuclear bomb, and it also announced that Germans had already begun experimenting with Uranium, according to Encyclopedia.com. The Manhattan Project required the construction of two colossal facilities: one in Oak Ridge, Tennessee and
In 1941, The United States began an atomic bomb program called the “Manhattan Project.” The main objective of the “Manhattan Project” was to research and build an atomic bomb before Germany could create and use one against the allied forces during World War II. German scientists had started a similar research program four years before the United States began so the scientists of the “Manhattan Project” felt a sense of urgency throughout their work (Wood “Men … Project”).
