Originally published in German in 1956. First English translation 1958. So it covers up to the claimed Soviet nuclear H bomb, and the 'Lucky Dragon' incident of supposed irradiated Japanese fishermen. Jungk was apparently a Berlin Jew, born 1913, who studied European classics and got a PhD in 'modern European history' - presumably Europe since the French Revolution.
I reread this to try to disentangle mythology from truth. Jungk as might perhaps be guessed says virtually nothing about the science or technology - or mistakes. There is (for example) no account of separation of U235; no account of why 'heavy water' might be important, or how it's isolated; no account even of where uranium was mined. Jungk says in effect that radioactive poison can now be made more or less indefinitely - but this seems not true since the supply of neutrons seemed/seems fixed by the amount of uranium mined. Jungk made little attempt to check anything, though there are a few letters to him from physicists.
Jungk's main attitude is rather awestruck reverence in quotation - for example, a Japanese physicist is quoted as saying only an atomic bomb could do this. This doesn't really work: for example, Jungk says hugely detailed calculations were needed. (He doesn't say what they were and in fact one has to wonder whether it's true - but I suppose if computers then resembled pocket calculators, well, they would be of some use. But if the need for elaborate calculations is true, how come the measured blast from explosions was supposed to be far greater than estimated?
Unfortunately Jungk is uncritical as regards the political material: as an example there's a whole section on Oppenheimer's fall, but although the type of building, sofa, characters of the nterviewee/interrogators, weather, tone of voice, etc etc are detailed, it's not made clear what he was charged with - let alone of course how serious it was.
An appendix is the 'Franck Report' to I think Stimson. This is full of comment on dangers of nuclear weapons, proliferation, treaties, control, and so on. Astonishingly, this was dated a few months before the first test, at night, in a remote country area, ten miles from observers, with full military secrecy! They had a lot to lose if their huge funding was found not to work.
