  Leó Szilárd - Wikipedia, the free encyclopedia
Szilard was probably the first scientist to seriously examine the science behind the creation of nuclear weapons, as he knew about the fictional "atomic bombs" described in H.
Szilard was well known to his colleagues as an eccentric, lightning-quick thinker who "seemed fond of startling people" with strange, seemingly incongruous, yet extremely perceptive statements and questions.
Although nuclear fission had not yet been discovered, Szilard was reportedly so annoyed at this dismissal that he conceived of the idea of the nuclear chain reaction while waiting for traffic lights to change on Southampton Row in Bloomsbury.

Szilard and his colleagues Eugene Wigner and Edward Teller hoped to gain the financial support of the United States Government in underwriting the cost of a definitive, large-scale experiment to prove that a sustained nuclear chain reaction was possible.

Szilard, experimenting in collaboration with Fermi, Zinn, and Anderson, proved the possibility of a nuclear chain reaction, but he may be best known for his role in the initiation of the Manhattan Project for developing an atomic bomb during World War II.

 Leo Szilard
Szilard had already tried to prevent all the theoretical and experimental work on uranium that was done outside of Germany from publication, and ran into several conflicts with other scientists, so the only other thing left for him to do was restrict access to the Congo uranium.
Szilard, however, was "an independent gadfly" of the project, in the words of Stephane Groueff: "He would rove through the labs, suggesting revolutionary approaches to the problems, sounding the alarm about Hitler's military advances, and often asking some young scientists to switch from one experiment to another.
Szilard went beyond the cost-benefit calculations justifying the murder of a hundred thousand innocent people in order to prevent the death of a million; he was able to see the long-term consequences of the weapon, which his contemporaries could not even grasp until it was too late.

 Leo Szilard and H.G. Wells, founders of the Green Left
Szilard was too sophisticated to think that the inductive logic of natural science could be transferred to the infinitely more obtuse and intractable questions of politics, and he readily acknowledged the rift between physical problems and social problems.
Szilard did not need to "obey" these commandments, for (in the words of his widow) they already reflected his spirit "like a portrait." Scientific inquiry, personal life, and social action were inseparable for him; he brought the same intellectual habits and moral values to an three.
Szilard's record of the interview does not say whether Khrushchev was amused, but the length of the ensuing conversation suggests that the Soviet premier had seen through the devices of the razor and the political wisecrack and understood that Szilard was more interested in peace than in political partisanship.

Leo Szilárd (February 11, 1898 - May 30, 1964) was a Hungarian physicist who worked on the Manhattan Project.
He hoped that the US Government, which before the war was much opposed to the bombing of civilians, would not use the bomb, as the only possible purpose of a weapon of that magnitude could be to slaughter civilians.
Before the war, Szilard had considered the US the one truly humane government in the world; that is why he chose to give THEM, over everyone else, the atomic bomb.

The Hungarian-born Szilard was at the epicenter of the Manhattan Project--indeed, he patented the first reactor design with Enrico Fermi--but his concern over the destructive uses of atomic power (and a degree of personal eccentricity) isolated him from the celebrity (and Nobel prizes) that came to other founding fathers of quantum physics.
Leo Szliard was a mental gypsy from the old world who saw the new world before most of the other "famous" thinkers of the 20th Century even opened their eyes.
