Why did the US develop the atomic bomb first?
President Truman authorized the use of the atom bombs in an effort to bring about Japan’s surrender in the Second World War. The Manhattan Project was the US government program during World War II that developed and built these first atomic bombs.
What inspired the atomic bomb?
In 1941 James Bryant Conant opened a liaison office between the British government and the National Defense Research Council of the United States. The Japanese bombing of Pearl Harbor on December 7, 1941, accelerated the development of an atomic bomb in the United States.

The modern atomic theory, which has undergone continuous refinement, began to flourish at the beginning of the 19th century with the work of the English chemist John Dalton.
Who split the atom?
Manchester is the birthplace of nuclear physics and this year marks 100 years since Ernest Rutherford ‘split the atom’ at The University of Manchester…or does it? In 1917, the Nobel Prize winner actually became the first person to create an artificial nuclear reaction in laboratories at the University.
When were the first atomic bombs made and tested?
The Manhattan Project atomic research team was formed, and the first atomic bombs were developed by the United States, from 1939 to 1945. The first test of the atomic bomb was on July 16, 1945.
How did Einstein contribute to the development of the atomic bomb?
Einstein suggested that the United States start building its own nuclear research centers and begin mining uranium. He described how a single atomic bomb, carried into a port by ship, could destroy the entire port and surrounding territories. This gave the U.S. a priority that had to be completed.
How did the use of the bomb affect other scientists?
The use of the bomb caused many other scientists to despair as well. Albert Einstein deeply regretted that he had written to President Roosevelt. He did not work on the Manhattan Project, but he had used his influence to encourage the start of the American bomb project.
Why did America decide to use the atomic bomb on Japan?
The decision to use the atomic bombs was prompted by Japan’s refusal to surrender. On August 6, 1945, Little Boy was dropped on the Japanese city of Hiroshima. It was detonated at 1,900 feet and missed its target by just 800 feet.
