World War ll
The Manhattan Project
In 1938, three chemists working in a laboratory in Berlin made a discovery that would alter the course of history: they split the uranium atom. The energy released while splitting,or fission, occurs is tremendous. When Eisenstein learned that the Germans might succeed in solving these problems, he wrote to president Franklin D. Roosevelt his concerns. Two other findings in 1940 and 1941 demonstrated that the bomb was feasible. It made building a bomb a top priority for the United States. In August 1939 Einstein wrote to president Roosevelt about how the Nazis are making a nuclear bomb. The first bomb was dropped on Hiroshima, Japan.
Nazi leader, Adolf Hitler, was born in 1889, in Austria and died in 1945, in Berlin, Germany. He was one of the most powerful dictators in the 20th century. After World War One, he rose to power in the National Socialist German Workers party, taking control of the German government in 1933. His attack on Poland resulted in World War One. By 1941, Germany occupied much of Europe and North Africa. When he invaded Russia and when America entered the war, Hitler started losing. He killed himself before the war was over.
