No they never did, it was a well known german who invented it actually. A very well known man indeed.
Which well known german was this???

The physicist Albert Einstein did not directly participate in the invention of the atomic bomb. But as we shall see, he was instrumental in facilitating its development.
In 1905, as part of his Special Theory of Relativity, he made the intriguing point that a large amount of energy could be released from a small amount of matter. This was expressed by the equation E=mc2 (energy = mass times the speed of light squared). The atomic bomb would clearly illustrate this principle.
But bombs were not what Einstein had in mind when he published this equation. Indeed, he considered himself to be a pacifist. In 1929, he publicly declared that if a war broke out he would "unconditionally refuse to do war service, direct or indirect... regardless of how the cause of the war should be judged." (Ronald Clark, "Einstein: The Life and Times", pg. 428). His position would change in 1933, as the result of Adolf Hitler's ascent to power in Germany. While still promoting peace, Einstein no longer fit his previous self-description of being an "absolute pacifist".
Einstein's greatest role in the invention of the atomic bomb was signing a letter to President Franklin Roosevelt urging that the bomb be built. The splitting of the uranium atom in Germany in December 1938 plus continued German aggression led some physicists to fear that Germany might be working on an atomic bomb. Among those concerned were physicists Leo Szilard and Eugene Wigner. But Szilard and Wigner had no influence with those in power. So in July 1939 they explained the problem to someone who did: Albert Einstein. According to Szilard, Einstein said the possibility of a chain reaction "never occurred to me", altho Einstein was quick to understand the concept (Clark, pg. 669+; Spencer Weart & Gertrud Weiss Szilard, eds., "Leo Szilard: His Version of the Facts", pg. 83). After consulting with Einstein, in August 1939 Szilard wrote a letter to President Roosevelt with Einstein's signature on it. The letter was delivered to Roosevelt in October 1939 by Alexander Sachs, a friend of the President. Germany had invaded Poland the previous month; the time was ripe for action. That October the Briggs Committee was appointed to study uranium chain reactions.
But the Briggs Committee moved very slowly, prompting Einstein, Szilard, and Sachs to write to FDR in March 1940, pointing again to German progress in uranium research (Weart & Szilard, pg. 119+). In April 1940 an Einstein letter, ghost-written by Szilard, pressed Briggs Committee chairman Lyman Briggs on the need for "greater speed" (Weart & Szilard, pg. 125+; Clark, pg. 680).
Research still proceeded slowly, because the invention of the atomic bomb seemed distant and unlikely, rather than a weapon that might be used in the current war. It was not until after the British MAUD Report was presented to FDR in October 1941 that a more accelerated pace was taken. This British document stated that an atomic bomb could be built and that it might be ready for use by late 1943, in time for use during the war (Richard Rhodes, "The Making of the Atomic Bomb", pg. 377+).
Einstein biographer Ronald Clark has observed that the atomic bomb would have been invented without Einstein's letters, but that without the early U.S. work that resulted from the letters, the a-bombs might not have been ready in time to use during the war on Japan (Clark, pg. 682-683).
The atomic bomb related work that Einstein did was very limited and he completed it in two days during December 1941. Vannevar Bush, who was coordinating the scientific work on the a-bomb at that time, asked Einstein's advice on a theoretical problem involved in separating fissionable material by gaseous diffusion. But Bush and other leaders in the atomic bomb project excluded Einstein from any other a-bomb related work. Bush didn't trust Einstein to keep the project a secret: "I am not at all sure... [Einstein] would not discuss it in a way that it should not be discussed." (Clark, pg. 684-685; G. Pascal Zachary, "Endless Frontier: Vannevar Bush, Engineer of the American Century", pg. 204).
As the realization of nuclear weapons grew near, Einstein looked beyond the current war to future problems that such weapons could bring. He wrote to physicist Niels Bohr in December 1944, "when the war is over, then there will be in all countries a pursuit of secret war preparations with technological means which will lead inevitably to preventative wars and to destruction even more terrible than the present destruction of life." (Clark, pg. 698).
The atomic bombings of Japan occurred three months after the surrender of Germany, whose potential for creating a Nazi a-bomb had led Einstein to push for the development of an a-bomb for the Allies. Einstein withheld public comment on the atomic bombing of Japan until a year afterward. A short article on the front page of the New York Times contained his view: "Prof. Albert Einstein... said that he was sure that President Roosevelt would have forbidden the atomic bombing of Hiroshima had he been alive and that it was probably carried out to end the Pacific war before Russia could participate." ("Einstein Deplores Use of Atom Bomb", New York Times, 8/19/46, pg. 1). Einstein later wrote, "I have always condemned the use of the atomic bomb against Japan." (Otto Nathan & Heinz Norden, editors, "Einstein on Peace", pg. 589).
In November 1954, five months before his death, Einstein summarized his feelings about his role in the creation of the atomic bomb: "I made one great mistake in my life... when I signed the letter to President Roosevelt recommending that atom bombs be made; but there was some justification - the danger that the Germans would make them." (Clark, pg. 752)."

Quoted From Article "
The Manhattan Project was a research and development program, led by the United States with participation from the United Kingdom and Canada,
that produced the first atomic bomb during World War II. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the US Army Corps of Engineers. The Army component of the project was designated the Manhattan District; "Manhattan" gradually superseded the official codename, "Development of Substitute Materials", for the entire project. Along the way, the Manhattan Project absorbed its earlier British counterpart, Tube Alloys.
The Manhattan Project began modestly in 1939, but grew to employ more than 130,000 people and cost nearly US$2 billion (roughly equivalent to $24.4 billion as of 2011[1]). Over 90% of the cost was for building factories and producing the fissionable materials, with less than 10% for development and production of the weapons. Research and production took place at more than 30 sites, some secret, across the United States, the United Kingdom and Canada. Two types of atomic bomb were developed during the war. A relatively simple gun-type fission weapon was made using uranium-235, an isotope that makes up only 0.7 percent of natural uranium. Since it is chemically identical to the main isotope, uranium-238, and has almost the same mass, it proved difficult to separate. Three methods were employed for uranium enrichment: electromagnetic, gaseous and thermal. Most of this work was performed at Oak Ridge, Tennessee.

The theory of nuclear weapons was created by albert einstein but the cost of developing the bombs was carried mostly by the american, british and canadian taxpayers.
Quoted From Article "Julius Robert Oppenheimer[note 1] (April 22, 1904 – February 18, 1967)[1] was an American theoretical physicist and professor of physics at the University of California, Berkeley.
Along with Enrico Fermi,[2][3] he is often called the "father of the atomic bomb" for his role in the Manhattan Project, the World War II project that developed the first nuclear weapons.[4] The first atomic bomb was detonated on July 16, 1945 in the Trinity test in New Mexico; Oppenheimer remarked later that it brought to mind words from the Bhagavad Gita: "Now, I am become Death, the destroyer of worlds."

Quoted From Article "Enrico Fermi (29 September 1901 – 28 November 1954)[1] was an Italian-born, naturalized American physicist particularly known for his work on the development of the first nuclear reactor, Chicago Pile-1, and for his contributions to the development of quantum theory, nuclear and particle physics, and statistical mechanics. He was awarded the 1938 Nobel Prize in Physics for his work on induced radioactivity.
Fermi is widely regarded as one of the leading scientists of the 20th century, highly accomplished in both theory and experiment.[2]
Along with J. Robert Oppenheimer,[3] he is frequently referred to as "the father of the atomic bomb".[4][5] He also held several patents related to the use of nuclear power."

The atomic bomb was largely funded and developed by the americans if anyone deserves to have nuclear weapons it is them.
