Before the atomic bomb was dropped on Japan, Leo Hillard, a scientist at the University of Chicago's Metallurgical Laboratory, was trying to stop the unprecedented bombing. Leo Szirard is a famous Hungarian-American nuclear physicist, inventor, professor at the University of Chicago, he conceived the nuclear chain reaction as early as 1933, after the Nazis came to power, he left his growing Europe to continue his research, and in 1939 assisted Albert Einstein to send a letter to US President Franklin Roosevelt, directly contributing to the launch of the Manhattan Project. Hillard himself had been involved in the Manhattan Project, but as the threat of Nazi Germany's atomic bomb project was eliminated, he began recommending to President Truman that the bombing of Japan be canceled. In the petition, he confessed that the atomic bomb in the possession of the United States has terrible destructive power, that it is sad that this huge force of nature that has just been discovered by mankind is used to destroy it, and that if more countries master this weapon technology after the war, then the world will be in great danger of destruction. Hillard distributed the petition widely in Chicago and Oak Ridge, collecting a total of 88 signatures, but Oppenheimer, a theoretical physicist at Los Alamos, refused to participate.

The petition quickly reached General Leslie Groves, who oversaw the Manhattan Project, who surveyed scientists at the Metropolitan Laboratory and found that only 15 percent wanted the atomic bomb to be used "in the most effective military way," and another 46 percent wanted "a military demonstration before the full use of this new weapon, giving Japan a new chance to surrender." These figures mean that 87 percent of Met's scientists support the use of the atomic bomb. In the end, Groves chose to shelve Hillard's petition without submitting it to President Truman. Later, atomic bombs eventually landed on Nagasaki and Hiroshima.
