Apparently, some translated samizdat version of this story was smuggled into the USSR and was read by Sakharov (the Russian equivalent to Oppenheimer) and actually changed his opinions about the nuclear testing program they were engaged in.
In general, I feel like Szilard doesn't get the attention he deserves for his huge contributions. That's probably because he really rubbed a lot of people the wrong way, who thought he was rude and egotistical. Fascinating life though-- also check out his refrigerator inventions/patents that he made with Einstein after they heard a sad story of a family dying in their apartment from a leaky old fridge.
