Albert Einstein visited the U.S. in 1933 when Adolf Hitler came into power and Albert Einstein did not go back to Germany since he was of Jewish ancestry. Albert Einstein knew that Adolf Hitler was anti-Semitic before the Nazi Regime was formed. He became a U.S. citizen in 1940 and on the eve of World War 2, he endorsed a letter to President Franklin D. Roosevelt alerting him to the potential development of 'extremely powerful bombs of a new type', and recommended that the U.S. begin similar research.
This led to the Manhattan Project.
The first nuclear testing of the bomb, by the Manhattan Project, which they dropped on Hiroshima, was conducted in New Mexico in July of 1945 in the Jornada del Muerto desert.
The U.S. with consent from the U.K, then dropped the nuclear bomb on Hiroshima in August of 1945, 1 month after the test and 5 years after the war had begun.
The concept of nuclear weapons being possible through the process of 'fission', first arose in 1938 by Otto Hahn and Fritz Strassmann and was theoretically explained by Lise Meitner in January of 1939. This led to the discovery of 'spontaneous Fission' in Russia in 1940.
After the war had begun, Germany put aside their nuclear investigation. The German Nuclear Weapon Project was postponed and the Military of Germany was being strengthened by the German's enrollment into the military.
Although Germany and Russia had the foundations of nuclear weapons during WWII, neither Germany nor Russia had nuclear weapons during World War 2.
