The method of making an atomic bomb was discovered by European scientists in 1938. A year later, Albert Einstein (1879-1955) sent a letter to President Franklin Delano Roosevelt urging him to initiate an American atomic weapons program because he feared that Nazi Germany might develop an atomic bomb, . After some delay, the $2 billion Manhattan Project was launched in 1942. 125,000 people were involved in this project at one time to produce uranium 235 and plutonium 239 at Oak Ridge, Tennessee, and at Hanford, Washington. In addition, thousands of scientists were to produce the bomb itself at Los Alamos, New Mexico.

By July 13, there were indications that the Japanese were seeking to end the war. Evidence of this is found in ex-Prime Minister Konoe Fumimaro's cable to the Soviet Union on July 12 which expressed a desire to end the war swiftly. On July 18, Truman had receive

There were a considerable number of foreigners among the hibakusha. For example, one report estimates that 25,000 - 28,000 Koreans became hibakusha. Because of the Japanese had brought many of these people from Korea, then a Japanese colony, for forced labor and discriminated against them even after World War II, the plight of the Korean hibakusha was worse than that of Japanese hibakusha.

The temperature at the hypocenter was estimated to be 3000 degrees to 4000 degrees celcius. For comparison, the melting point of an iron bar is approximately 1500 degrees celcius. As a result, those who were exposed to heat rays died within 1 week. Not only their skin, but also their internal organs were ruptured by the heat. People as far away as 3.5km from the hypocenter also suffered skin burns from the heat rays. Shadows were imprinted on concrete walls, and the surface of granite stones and roof tiles near the hypocenter melted.
