Who was the first scientist to develop atomic bomb?

Answer 1

Ernest Rutherford, in 1919, was the first to split an atom, though it was nitrogen, and thus there was no power generation or explosion. In 1932 Sir John Cockcroft and Ernest Walton were the first to cause a nuclear reaction by the fission of an atom. Enrico Fermi, however was the first to fission uranium, in 1932, though at the time he did not fully appreciate the consequences of this discovery. Otto Robery Frisch and Lise Meitner were the first to realize the potential energy produced by the fission of uranium, however, and in a latter experiment, Frisch proved the theory.

The first person to ever realize its potential as a weapon, though, was the Hungarian physicist Leo Szilard, who realized, after experimentation, that the amount of neutrons released by the fission of uranium (two on average) could produce a nuclear chain reaction, which could lead to a massive explosion. Fearing the use of this reaction as a weapon by a facist government, however, Szilard kept his discovery secret, and convinced others to do the same, but the Joliot Curie group published the exact same results, coming to the same conlusion as Szilard.

However, the man who is generaly regarded as the "father of the A-bomb" is J. Robert Oppenheimer, who led the Manhattan Project in the United States, which produced the first ever nuclear weapon.

H.G. Wells was the first to envision a nuclear weapon driven by nuclear fission, when he wrote of "air dropped 'atomic bombs'" in his 1914 novel, The World Set Free. At the time, Wells did not know of the destructive power the such weapons would one day harness. Leo Szilard latter said that this novel had been the inspiration for his research on nuclear fission.And he has tested the bomb offensivly in japan
No one found it!

Leó Szilárd invented it in 1933 while living in London and patented it in 1934, his patent was granted in 1936 and the British Admiralty promptly bought the patent and classified it. However no fuel was known that could make the patent work to build an actual bomb.

In early 1939 a team of scientists working in Germany and Sweden discovered that one isotope of uranium (U-235) could fission when struck by a neutron and produce more neutrons that could cause more fissions. While these scientists did not know of Leó Szilárd's patent (as it was classified) they rapidly figured out everything Leó Szilárd had in 1933 now that they had a usable fuel.

In August 1939, prominent physicists Leó Szilárd and Eugene Wigner drafted the Einstein-Szilárd letter, which warned of the potential development of "extremely powerful bombs of a new type". It urged the United States to take steps to acquire stockpiles of uranium ore and accelerate the research of Enrico Fermi and others into nuclear chain reactions. They had it signed by Albert Einstein and delivered to President Franklin D. Roosevelt. Roosevelt soon authorized preliminary studies.

In 1942, with the United States now at war, Roosevelt decided to begin full scale development of these bombs and authorized the Manhattan Project.

In June 1944, the Manhattan Project employed some 129,000 workers but after construction was complete this declined to 100,000 workers.

The first bombs were ready in the summer of 1945.

Answer 2

Atomic Bomb Scientists

Though not involved in developing the Atomic Bomb, Albert Einstien, along with other scientists, told President Roosevelt that Germany had plans to purify uranium-235 which could be used in an atomic bomb. Not long after that, the US government began what was called "The Manhatten Project." The goal of the project was to expediate research that would lead to the production of a viable atomic bomb.

Harold C Urey and his peers at Columbia University devised an extraction system for the uranium and Ernest O. Lawrence from the University of California in Berkley devised a method of magnetic separation of the isotopes.

Scientists who helped put the bomb together were: J. Robert Oppenheimer, the overseer of the Manhatten Project, David Bohm, Leo Szilard, Eugene Wigner, Otto Frisch, Rudolf Peierls, Felix Bloch, Niels Bohr, Emilio Segre, James Franck, Enrico Fermi, Klaus Fuchs and Edward Teller.

Deb

most of the credit though should be given to Enrico Fermi. In 1938, Fermi received the Nobel Prize in physics at the age of 37 for his "demonstrations of the existence of new radioactive elements produced by neutron irradiation, and for his related discovery of nuclear reactions brought about by slow neutrons". Later Fermi and Szilard's reactor work was folded into the Manhattan Project.

Answer 3

The German physicist Albert Einstein warned President Franklin Roosevelt that the Nazis would use atom energy bombs. Wanting to produce them first the president created a top-secret operation called the Manhattan Project. The scientists in this project created the atomic bomb.They were droped on Nagasaki and Hiroshima Japan during World War 2.

Answer 4

Well the Germans were the first to think of it the Russians were the first to make one and America is the first to use it.

Wrong, Leo Szilard a Hungarian invented the Atomic Bomb in 1933 (but couldn't build it himself at the time), the Russians did not make one until 1949, four years after the US made and used their first three in 1945. The Russian bomb was a clone of the American Trinity/Fatman design made from plans stolen by Klaus Fuchs and Ted Hall. Stalin would not let his scientists design an Atomic Bomb themselves until the stolen plans were tested.

Answer 5

The answer most people are looking for is Robert Oppenheimer. But this is incomplete at best.

There was a gigantic effort by the US to develop the Atomic Bomb (The Manhattan Project). This project used hundreds of scientist and thousands of people to develop the first Atomic Bomb.

The Manhattan Project was implemented by President Franklin Roosevelt in no small part due to two letters sent to him by Albert Einstein. In these letters, Mr. Einstein refers to the work being done by Enrico Fermi and Leo Szilard.

The Manhattan Project was assigned to General Leslie Groves. He in turn recruited theoretical physicist J. Robert Oppenheimer to lead the "army" of scientists in the development of "the gadget" -- code name for the Atomic Bomb.

So, who was the first scientist to develop the Atomic Bomb?

-Robert Oppenheimer directly led a group of about 100 scientists that developed the first working device.

-Enrico Fermi was the first to design a theoretical device that could be an Atomic Bomb

-Leo Szilard was the first to propose the feasibility and destructive power of such a device (for the Allies) and warned of the possibility that German scientists may already be working on such a device.

-Albert Einstein first proposed that enormous amounts of energy could be extracted from just a small amount of matter (e=mc²). He also used his fame to get President Roosevelt's attention to the possibility of an Atomic Bomb.

Other scientist that helped develop the groundwork for the bomb are

Niels Bohr (Theoretical Physics), Marie Curie (Discovered Radium) and Otto Frisch. Otto Frisch is credited as discovering fission which is the reaction that makes an atomic bomb possible.

Answer 6

The scientist who developed the atomic bomb was J. Robert Oppenheimer.

Answer 7

idk all of 'em, but the most important 1 was Albert Einstein.

Answer 8

No one found it. It was created by a large group of scientists and engineers in the 1940s

Answer 9

Leo Szilard in 1934.

Answer 10

some person from Harvard
