During his final years, Szilard served as a fellow at the Salk Institute for Biological Studies in La Jolla, California, which he had helped to found in 1963.
Szilard’s ultimate goal was for President Truman to read his petition and consider the moral questions raised by the use of the atomic bomb.
In another story, “My Trial as a War Criminal,” Szilard presents a revealing, though fantasized, view of himself standing trial for war crimes against humanity after the United States had unconditionally surrendered to the Soviet Union, after losing a war in which the U.S.S.R. had unleashed a devastating germ warfare program.
Leo Szilard (1898-1964) was a Hungarian-born American physicist and inventor who played a key role in the development of the atomic bomb. Though he vocally opposed using the bomb in war, Szilard felt it was important to perfect the super-weapon before Nazi Germany.
Leo Szilard drafted the petition below to the President in the summer of 1945 attempting to avert the U.S.'s use of the atomic bomb against Japan.
In 1955, Szilard and Enrico Fermi jointly received the patent for a neutronic reactor. Despite his express desire to develop atomic weapons before Nazi Germany, Szilard publicly stated his opposition to using the bomb in war.
Official A-Bomb Justification: Save US Lives According to Truman and others in his administration, the use of the atomic bomb was intended to cut the war in the Pacific short, avoiding a U.S. invasion of Japan and saving hundreds of thousands of American lives.
Szilard was the chief physicist at the Chicago Metallurgical Laboratory from February 1942 to July 1946. He worked for Arthur H. Compton, the head of the Met Lab. Szilard helped build Chicago Pile-1, the first neutronic reactor to achieve a self-sustaining nuclear chain reaction.
He drafted the Szilard petition advocating a demonstration of the atomic bomb, but the Interim Committee chose to use them against cities without warning. After the war, Szilard switched to biology. He invented the chemostat, discovered feedback inhibition, and was involved in the first cloning of a human cell.
July 1945The Szilárd petition, drafted and circulated in July 1945 by scientist Leo Szilard, was signed by 70 scientists working on the Manhattan Project in Oak Ridge, Tennessee, and the Metallurgical Laboratory in Chicago, Illinois.
Why did supporters of using the atomic bomb reject the idea of dropping one on a deserted island? They thought the radioactive fallout was too dangerous. They thought it would make Japan fight even harder. They did not want other nations to know about the bomb.
President Harry S. Truman, warned by some of his advisers that any attempt to invade Japan would result in horrific American casualties, ordered that the new weapon be used to bring the war to a speedy end. On August 6, 1945, the American bomber Enola Gay dropped a five-ton bomb over the Japanese city of Hiroshima.
Which of the following is a common argument in favor of the development of nuclear weapons? This development paved the way for non-military use of nuclear energy. You just studied 8 terms!
Truman believed that the bombs saved Japanese lives as well. Prolonging the war was not an option for the President. Over 3,500 Japanese kamikaze raids had already wrought great destruction and loss of American lives. The President rejected a demonstration of the atomic bomb to the Japanese leadership.
Robert OppenheimerRobert Oppenheimer, “father of the atomic bomb.” On July 16, 1945, in a remote desert location near Alamogordo, New Mexico, the first atomic bomb was successfully detonated—the Trinity Test.
In December 1938, over Christmas vacation, physicists Lise Meitner and Otto Frisch made a startling discovery that would immediately revolutionize nuclear physics and lead to the atomic bomb.
Shaken by the destructive force of the weapon he had helped to create, Szilard decided to dedicate the rest of his life to nuclear safety, arms control, and the prevention of further development of nuclear energy for military purposes.
In January 1938, with the impending war in Europe threatening his work, if not his very life, Szilard immigrated to the United States, where he continued his research in nuclear chain reactions while teaching at New York’s Columbia University.
While experimenting with chain reactions at London’s St. Bartholomew's Hospital, he discovered a method of separating the radioactive isotopes of iodine. This research led to Szilard being granted the first patent for a method of creating a nuclear chain reaction in 1936. As war with Germany grew more likely, his patent was entrusted to the British Admiralty to ensure its secrecy.
Early Life. Leo Szilard was born Leo Spitz on February 11, 1898, in Budapest, Hungary. A year later, his Jewish parents, civil engineer Louis Spitz and Tekla Vidor, changed the family’s surname from the German “Spitz” to the Hungarian “Szilard.”. Even during high school, Szilard showed an aptitude for physics and mathematics, ...

In 1927, Szilard was hired as an instructor at the University of Berlin. It was there that he published his paper “On the Decrease of Entropy in a Thermodynamic System by the Intervention of Intelligent Beings,” which would become the basis for his later work on the second law of thermodynamics .
Forced to return to Budapest to recover from the dreaded Spanish Influenza of 1918, Szilard never saw battle. After the war, he briefly returned to school in Budapest, but transferred to the Technische Hochschule in Charlottenburg, Germany, in 1920.
