    Checked out the documents. These are documents written in the sixties, i.e. twenty years after Heissenberg supposedly tried to convince Bohr to build a german A-bomb. Doesn't really add anything interesting to the story. Bohr had his version, Heissenberg his. Neither one can back it up.


    Why is this such a big deal anyway? Heissenberg, one of many famous modern physisists might have been a Nazi. So was almost the entire german population for crying out loud. Most of them did not know the entire story, and later on most of them understood that they had been horribly wrong. Let it rest.

      I think many Germans who were living in Germany in the 30s and 40s would balk at the statement that "almost the entire german population" were Nazis. There were very large numbers of them that opposed Hitler and Nazism, either privately or publicly (those who did so publicly were not around much longer however). Just because the leader of a country is something, do not assume that all, most, or even some of the citizens agree with his beliefs.

      2) Hitler was legally elected Chancellor, but anyone who has ever read the events surounding Hitler's rise to ultimate power after Paul Von Hindenburg's death knows that it was a thrown election. Reichstag members were forced at gunpoint to vote in fvor of granting Hitler ultimate power. This was partially also the fault of a loophole in the 1919 Weimar constitution. After the war, the loophole was definately taken out of the new constitution so that the role of President and Chancellor are completely separate, with President being an entirely ceremonial role.

      3) The Pan-Germanism movement had its roots in Austria, with many small parties and youth movements recorded even as early as 1907. National Socialism was much more than just Hitler, and much more than just Germany. As one poster noted, there were many foreigners who supported the anti-semetic (which had been brewing in Europe for _centuries_.), anti-bolkshevik, and pan-germanic aspects of the NSDAP platform.

Plus, I'm speaking loosely here, so this isn't my considered historical opinion, just my offhand thoughts as a semi-informed person. Oh, and I don't have any of the books and documents here to refer to, so I may make factual errors. - I think that about covers it

      1. I realise you're just repeating what you saw on TV, but I think that either the TV program really twisted the history hard, or you didn't quite understand it correctly. I don't think anybody's actually seriously suggested that H tried to recruit B for the German A-bomb program.
      H said that he informed B of the German program in order to get his agreement that all scientists everywhere should refrain from building a bomb (knowing, of course, that B had contacts in Britain and the United States).
      B said that H informed him of the German program for... well, he never quite explained it. From what he said after the war, he was just really shocked by the revelation that H was working on the program and was very upset by the idea that his friend might be working against the common interest of humanity.

      2. I've read through the letters and they *don't* substantially clear up the case. Perhaps more documents to be released will tell us more, but these documents simply give us a lucid and interesting account of B's outrage. He says things like , but he doesn't specifically tell us *what those words were*. Not having read B's documents myself, I can't tell you whether he meant things like this seriously, or whether it was just a figure of speech, nor do I know how accurate his memory would have been. What we do know is that his impressions of that day were coloured deeply by his dismay at H's pro-Nazi comments prior to the private meeting between H and B. Which brings us to...

      3. It is unclear as to how deeply H supported the Nazi regime, if at all. Now I am not an H biographer, and I would like to refer you to the many fascinating books written about him for actual authoritative comment. Having said that, a Coles Notes version is that H's relationship with Nazism and with German nationalism was extremely complex and ambiguous (for any historians out there, I discuss this merely because I'm sick to death of hackers telling me "just go program it yourself" and I think that telling them "just go read a bunch of history books yourself" would be just as bad). I would say that most observers believe that H saw himself as a patriotic and loyal German, but not a supporter of the Nazis per se. There were many Germans, at the time, who believed that the Nazis were, rightly or wrongly, the official government of Germany and that to go against them would be an act of treason against Germany (just to make it clear: I believe, personally, that this attitude was wrong, wrong, wrong, and that the Nazis were bad, bad, bad. ok? so nobody make like I'm defending this or anything). H seems to have held this opinion, at least in the period before the war (but more on that later).
      Now it actually gets way more complicated than this because, I am told, in German culture there were different concepts for treason against the nation and treason against the government, but that doesn't change the fact that we *have* to keep this idea in mind (keep in mind that I'm not an expert on German culture in the middle of the 20th century). Many Germans, having courageously resisted the Nazis, had to face the stigma of having "betrayed their country" during the war.
      If you want to read a fascinating and very readable account of the way these ambiguities played out among the German atomic scientists, there is a book called _Hitler's Uranium Club: The Secret Recordings at Farm Hall_ edited by Jeremy Bernstein.

      This is where the plot thickens because, if we actually look at the historical record, there *was no* Nazi atomic bomb program. "What?" you say "no a-bomb program? Then what are we arguing about?"
      It turns out, and bare with me here, because I don't remember the chronology, that the Nazis got wind of the idea of an a-bomb, and called in a bunch of atomic scientists to ask them about it. The answer they got was, you guessed it, ambiguous. They were told that, yes, it would be possible to build a bomb and, yes, it would be powerful and reasonably small. However, the scientists also hinted that such a program would consume an inordinate amount of resources, might not work. Now that was a reasonable thing to say, and doesn't necessarily cast doubt on their commitment to helping the war effort. But what comes next rings alarm bells: when asked whether they could guarantee that the chain reaction in a fission explosion would be contained - that is to say, to guarantee that it would not start a chain reaction in the rest of the matter in the world and turn the entire planet into one great nuclear fission fireball - they said that they could not. Now anybody who knows a little nuclear physics knows that this was a preposterous statement. Why would a nuclear explosion magically turn the air into fissionable material? You need constant core-of-the-sun like temperatures to do that. The best explanation is that the German scientists had *very* cold feet about running a bomb program.
      Incidentally, this was not necessarily because they feared arming Hitler with an a-bomb. There were other good reasons for them to not want to run an a-bomb program I won't go into here for lack of space and time (rimshot!).
      In the end, the scientists got to have their cake and eat it to. Substantial amounts of government money were put into a *reactor* program, allowing them to say in a job and keep their students away from the Eastern Front. At the same time, they weren't burdened with the huge and risky job of trying to produce an atomic bomb for the state.

      So I said I'd get back to why H might have changed his views during the war... Several writers have pointed out, I think rightly, that H was "betraying" the German war effort by telling B about the possibility that the Germans might develop an a-bomb at all. H *knew* that B had contacts outside Nazi-occupied Europe. H *knew* that B was an ardent anti-Nazi. He was an intelligent man. He could not have been blind to the fact that B would certainly repeat every word he said to his contacts in Sweden and thence to Britain. So however we interpret the meeting, I cannot see a way in which it would support the idea that H was an ardent Nazi trying to strengthen the Nazi cause. It just doesn't make sense.

      But that's the trouble, you see. None of it makes perfect sense. Nobody will ever know precisely what happened in that meeting or why, but if I had to guess, I would say that H was conflicted about what to do. He was mixed up. On the one hand lay, what her perceived to be, his duty to the state and his genuine patriotism. On the other hand lay his fear of the destructive power of the bomb in anybody's hands. Probably, on a third hand, lay his duty to science, and then on a fourth hand his friend and so on and so on (and yes, I'm aware of the fact that I totally mangled that metaphor).

      One very important fact to remember is that the Russians (and Germans) around this time were using an incorrect estimate of the cross section of uranium, which did seem to indicate that sustained fission was not possible.

      To be more precise, the wrong cross section the Germans (Bothe and Jensen) obtained was not for uranium but for inelastic neutron scattering in graphite. Neutron scattering, i.e. the slowdown of fast neutrons generated in a fission process to thermal energies is an important factor in achieving a chain reaction, because only slow (thermal) neutrons are efficient at fissioning further uranium nuclei. This so called "moderation" process provides the essential link between the different stages of a nuclear fission chain reaction.

      The following paragraph, found at the history page of the KWImF (Kaiser-Wilhelm Institut für medizinische Forschung), now MPImF (Max-Planck Institut für medizinische Forschung), Heidelberg, where Bothe did his neutron moderation research is interesting in this context:
      Two facts in this controversy are quite clear: first, although Bothe had used the purest form [of graphite] available to the Germans, the graphite he used contained minute traces of boron; second, it was this contamination that made the graphite ineffective as a moderator. It is commonly believed that Bothe made a crucial mistake in not noticing the presence of the contaminating Boron. Gentner, however, attempted to set the record straight in 1980 as he lay upon his deathbed. Writing the last letter of his life to respected colleagues, he claimed that Bothe knew full well of the trace boron, as well as its implications. According to Gentner, Bothe simply did not know where or how to obtain a more pure sample of graphite.

      To state it more clearly: Bothe knew that his contaminated graphite made it unusable for moderation. However he didn't announce that he had contaminated graphite nor that more pure graphite might have worked, therby ruling out graphite as candidate for moderation, leaving only the other candidate, D2O (heavy water), of which the production facilities were sabotaged by the Allies. Whether this non-disclsure was a passive act of delaying The Bomb or not, will probably never be known with certainty.

      There was an official event at a german "cultural" institute which Bohr as he says "of course could not attend" followed by this private meeting at the Niels Bohr institute.

      Also do not forget that there were another person in the meeting, and while his "memory" is as suspect as Heisenbergs, his recollection is the same.

      Niels Bohr provably had possesed the data to indicate that a bomb would be possible for at least one year at the time, but was not in any way in contact with the allied program until he escaped from Denmark via Sweden shortly after and partly because of the meeting with Heisenberg.

      It is also important to remember that Hitler did not appreciate science, engineering yes, but not science. It is unconceiveable that he would have dedicated the necessary funds to create a german bomb, without some pretty hard evience and demonstrations.

      The claim that the nazi program was mostly for power-generation therefore sounds very credible.

      Heisenberg were fully aware of these things, in particular that even if physically possible, the bomb would be politcally out of reach.

      Therefore one cannot easily dismiss the claim that Heisenberg, convinced by nazi propaganda that the nazis would win, was merely tried to protect his old friend Bohr by getting him onto the victors bandwagon.

      In other words: Heisenberg probably tried to say something between the lines and Bohr missed it, and Bohr being better informed about the real standing of the war was unlikely to be swayed anyway. (Bohr could listen to BBC, Heisenberg could not for instance).

      I think the fact that no evidence has been found which indicates that Heisenberg actually did anything more than think about the bomb should be credited him, as for being convinced by the nazi propaganda, he was already punished more than fair is for that.

      From Could Germany Have Won the Second World War?

      The answer: yes.

      I think that the USA, and to a lesser extent the USSR, held what might be called the decisive advantage in WW II. By which I mean that these two countries, singly or together, had the resources, manpower, and material to decide the war in favor of either the Axis or the Allies. Had neither become involved in the war in Europe, it would likely have become a stalemate; Germany and Italy would not have been able to conquer the British Empire, and the British Empire would not have been able to conquer Germany and Italy. Whichever side either of these two countries joined would have the advantage.

      Once Hitler opened a second front by attacking the USSR, the Nazis were doomed. They did not have the resources in terms of people or material to defeat both the British Empire and the USSR simultaneously. The USSR probably did more than any other combatent to drain the German war machine. The Third Reich was bleeding to death in front of Leningrad, Moscow, and Stalingrad, even before it was pulverized from the air by the Western Allies.

      Probably Germany's best (though slim) chance to defeat the USSR would have been to talk Japan into attacking the USSR from the east (and leaving the US strictly alone). Initally, I suspect that Hitler was too arrogant to ask his Asian ally for help, even though he needed it desperately. Later, it was too late for both Germany and Japan. Also, the Japanese did not want to fight a war in Siberia that they probably could not win, especially as their Army was heavily engaged in China. They were a naval power, and the IJN could not contribute much to a war against the USSR. Of course, the IJN could have contributed a lot to a war against the Royal Navy in the Pacific and Indian Oceans, but that would have almost certainly brought the US into the war, an event that Germany was trying to avoid. Ultimately, Japan had less to contribute to a German victory than the USSR had to contribute to a British victory, so any Japanese strategy would probably have failed.

      Similarly, once the US entered the war on the Allied side, Germany was doomed. Even if Hitler had refrained from attacking the USSR, America simply had too many resources. Just as in the First World War, the US and the British Empire (plus most of the rest of the Western Hemisphere) would have eventually won a war of attrition.

      Again, probably Germany's best hope would have involved Japan and the USSR. If Hitler had refrained from attacking the USSR (Japanese diplomats were trying to get the USSR to join the Axis when Germany attacked, thereby demonstrating that at least some in the Japanese government had a much better concept of global strategy than Hitler did), and instead convinced both Japan and the USSR to join the Axis and help Germany, Italy, and their allies against the British Empire, the US, and their allies, it would have been a long and bitter war indeed, perhaps another stalemate. The posibility of stalemate or Axis victory would have been enhanced if Hitler also forced Spain into the war on the Axis side, taking Gibralter, driving England from the Mediterranean, and protecting Italy.

      In fact, of course, Hitler did open a second front by attacking the USSR, and the US and UK made the European war their first priority after Japan drew the US into the war on Dec 7, 1941. So even though Germany gained Japan as an active ally, she was doubly doomed. By which I do not mean to imply that defeating Germany (and Italy and Japan) was easy. In fact, it was a long, costly, dangerous, bloody road to victory. But, the odds favored the Allies.

      Fortunately, none of the Axis heads of state had any plan or strategy for a joint war effort, so the Allies were able to defeat them piecemeal. And the Japanese, who at least had a pre-war grand strategy in the Pacific, over extended themselves after their unexpectedly easy initial victories, and hastened their own defeat.

      Since I have considered the possibility of the USSR fighting on the Axis side in WW II, it is only fair to examine the scenerio of the US joining the Axis. Had Hitler not attacked the USSR (and the USSR remained neutral), and had the US unexpectedly joined the Axis, then:

      A major war would have been fought in North America, as Canada was already at war with Germany.

      After (if) the US defeated Canada, plus Australia, New Zealand, and the rest of the British Empire outside of the UK (maybe with the help of Japan [!] in the Pacific and Indian Oceans), the US Navy could neutralize the Royal Navy in the Atlantic, and the US and German Armies and Air Forces together could defeat the RAF, invade the UK, and win the war for the Axis. Then, Germany could have attacked the USSR with a reasonable chance of success. Of course, politically, there was zero chance of such a thing happening. I would like to make a few comments about Adolf Hitler, since he personified the Third Reich, and made all of the strategic decisions. I regard Hitler as a superb (if evil) politician with great political insight. This allowed him to gain power, re-arm Germany, and gobble-up parts of Europe with impunity.

      Once the war started, however, his weaknesses became evident. He had some tactical sense, probably due to his experience in WW I as a combat infantryman. But, he was a very poor strategist. As far as I can tell, he never had a "grand strategy." By which I mean a clear set of goals for the war and a plan to reach them. Hitler was, in fact, taken by surprise when England and France declared war on Germany. He had expected to partition Poland without fighting a major war, and had no plan beyond defeating Poland. Hence the period of "Phony War" after the defeat of Poland, while the German generals planned the campaign against France. When Italy joined the war, Hitler and Mussolini made no serious attempt to devise a common strategy. In fact, Mussolini's military mis-adventures in Greece and North Africa drained away valuable German military resources. After the defeat of France, Hitler seemed to have no idea what to do next, no plan at all for defeating the British Empire. Instead, he formulated his plan to attack the USSR, against the advice of his generals and without consulting his allies, and sealed the fate of Germany. Hitler fought the whole war on an "ad-hoc" basis, a campaign at a time. This lack of any coherent strategy cost Germany dearly. After Japan attacked Pearl Harbor and brought America into the war, Hitler made no attempt to formulate a common strategy with Japan. Again, he was taken completely by surprise (In truth, the Japanese leaders did not consult with Hitler, either, and may not have had much respect for him. Before the war, Admiral Yamamato declined an offer to meet with Hitler when the Admiral was traveling across Germany). I have always blamed this failure to consult with his allies, at least partly, on Hitler's arrogance. Hitler generally seemed to believe himself superior to his allies, as if he knew more. In fact, in terms of overall strategy, he knew less.

      Interesting speculation, but probably incorrect. Germany did ask for Japanese help against the USSR and was flatly refused. The Japanese were terrified of the USSR entering into the war in East Asia- they had gotten their clocks cleaned when they tangled with the Soviets earlier- and bent over backward to avoid giving the Soviets a reason to attack. This included an absolute refusal to attack Soviet flagged ships. This allowed the U.S. to send about 50% of its Lend-Lease cargo to the USSR through Vladivostok without risk of attack just by reflagging the ships as Soviet.

They really didn't think it could be done. Was that due to Aryan superiority beliefs or due to their science, hard to say.

    One story told by my history of science prof (he had interviewed Teller, Groves, Oppy, Szilard, etc.) was that Max Born was given the assignment of calculating the neutron cross section of graphite. This is useful for determining how much the neutrons coming out of a fission would be slowed, so they can hit another nucleus. For a reactor to work, they need to be slowed a little but not absorbed. Hence the need to know the cross-section.

    He apparently goofed with the decimal points, and wound up "proving" that graphite would never work. Pretty surprising since they had a small reactor going in Paris shortly after the city fell, moderated by graphite.

    That's why the Nazis kept trying to build heavy water plants - they thought that was the only possible reactor medium to use. But heavy water plants are fairly obvious targets, and Allied saboteurs took most of them out.

In a book by a Swiss journalist (Brighter Than a Thousand Suns )Heisenberg claims that because of his refusal to work on the bomb the Nazis did not obtain it. The problem with his version is the fact that transcripts were taken secretly in the U.K. where many of the German nuclear physicists were held after being captured in Germany by the allieds (out of fear they could work for the Russians later!). From these transcripts it is concluded that the German effort concentrated on building a reactor to breed plutonium and use that as bomb fuel (hence the importance of heavy water, which is used to moderate reactors). It is very likely that the Germans overestimated the amount of fissible uranium needed for a chain reaction (critical mass) by a huge amount and therefore did not attempt to separate uranium isotopes.
      The problem with Heisenberg was therefore perhaps not so much his role in WWII, but his dramatic reinvention of his role after the war.

    He gave an interview with the Süddeutsche Zeitung one or two days ago. His recollection of the meeting is rather interesting (the interview is in German, sorry).

    Firstly, he says that Heisenberg started an A-bomb project in 1939, in which Weizsäcker took part, but by 1941 they came to the conclusion that they would not be able to succeed before the war was over. The problem was the tremendous effort needed to separate the isotopes. So from 1941 on they were only interested in building a reactor. Once that worked (it never did, as the heavy water production was sabotaged) there might have been the possibility to create Plutonium and build a bomb with that. But they didn't expect this to happen before the war was over by conventional means.

    The reason Heisenberg went to see Bohr, according to Weizsäcker, was that they didn't want the Americans or the British to build a bomb either. If they stated publically that they're not working on a bomb, then of course nobody would have believed them. But Heisenberg thought that they might believe Bohr. So he hoped that Bohr could convince the Allies not to build the bomb either. This was not motivated by pure pacifism - he didn't want Germany to get nuked.

    In 1941 the war looked pretty good for Germany, they were winning on all fronts. So basically Heisenberg believed that a German victory was inevitable, but with conventional weapons. He tried to explain this to Bohr, who was shocked. Bohr may have understood Heisenberg's "inevitable" to mean that he WAS working on a bomb, and planning to use it. But Weizsäcker suggests that Bohr may well have understood correctly, and didn't want the Germans to win (conventionally), and therefor figured that the Allies would have to build a bomb, to avoid a Nazi victory.

    What we can accept as quite reliable, is the following: (a) Heisenberg did lead an A-bomb project from 1939 to 1941. (b) He came to the conclusion that he couldn't build a bomb before the war was over. (c) He continued working on a reactor from 1941 onwards (possibly with the option of producing Plutonium for later weapons use).

    And what also seem quite plausible: (d) that he tried to convince Bohr that he was only working on a reactor, not a bomb. This is what he claimed afterwards, and is backed up by Weizsäcker. Many people might not believe these two, so here is another interesting piece of the puzzle:

    I read some time ago, either in Physics Today or in Scientific American that when Bohr came to Los Alamos, he brought with him a sketch which Heisenberg had made during his 1941 visit. Bohr claimed it depicted a bomb which Heisenberg was building, but the people at Los Alamos recognised it as a heavy water reactor. As far as I remember, the sketch depicted a large bottle, filled with water (presumably heavy water, but only labelled "H2O"), and some stuff inside. Can anybody dig up this sketch on the net? At any rate, this strongly suggests that Bohr had misunderstood Heisenberg, and mistook Heisenberg's reactor for a bomb.

    For instance, Gitta Serenys excellent
    book "Albert Speer: His battle with truth".
    (Albert Speer was the Nazi minister of armaments during the latter part of the war).

    In the book Sereny notes that Speer, in a letter to a friend from Spandau prison after the war,
    wrote of Heisenbergs engagement in developing an A-bomb, and how he had they had been short of funds.
    According to the book, Speer remarked in the letter something to the extent of: "Now, I suppose he'll claim he didn't want the bomb built, and didn't ask for funding".

    This is, in fact, what Heisenberg claimed after the war. However, Speer could not have known this, since the prisoners in Spandau were not allowed to read newspapers or have any correspondence with the outside world.
    (With the exception of the contraband letters)

  80. Points to ponder by Spinality · · Score: 3, Insightful

    From my reading of the current material, and of other sources:

    1. Heisenberg took a substantial risk visiting Copenhagen and discussing secret and dangerous information with Bohr. We don't know exactly what was on his mind, but he wasn't doing this lightly.

    2. Heisenberg didn't like his fascist government; but he was still a patriot and wanted to do what was good for his people in the long run.

    3. In 1941, it was a very reasonable conclusion that Germany would win the war. Most people feared this. It would not be unreasonable to plan accordingly.

    4. Heisenberg was very, very smart.

    5. Bohr was troubled by what he saw as inconsistent and inexplicable behavior. He was surprised and concerned, at the time and later, and he sought in vain to understand his friend's words and actions, which seemed clear but inexplicable to him.

    6. After the war, Heisenberg felt bitter and misunderstood, and avoided discussing wartime events after having received censure from many sides.

    Assume, for the moment, that in 1941 Heisenberg a) thought Germany would win the war, b) hoped Bohr was aware how serious a threat was posed by nuclear weapons, c) wanted to prepare for good humane postwar German physics, and d) deliberately but secretly focused German research efforts on avenues leading to peaceful applications. How would his behavior have been different? Who would have been aware of this lonely struggle, at the time or later? And, assuming this were all true, how bitter and frustrated would he feel after the war, being blackguarded for actions that (if all were known) should be seen as heroic?

    The historical record is clearly ambiguous, and there are certainly valid interpretations of events that show him in a bad or foolish light. But this was an extraordinary man, dealing with titanic issues at an extraordinary time. I am more inclined to give him the benefit of the doubt. The great scientists I've known have tended to share a common trait: intellectual honesty, to the point of ruthlessness and even self-destruction if necessary. The great thinker is rarely petty of self-deceptive about important issues. So I have a hard time picturing Heisenberg conducting decades of revisionism to whitewash over bad behavior. I find it more likely that Bohr misunderstood his brief exchange with a troubled and tortured man, a man who was trying to do what he thought was right in a difficult situation. Bohr's own mystification with Heisenberg's actions is clear in the draft letters.

    We won't ever have a certain resolution to this question, because letters and recordings only reveal certain kinds of information. The truth was hidden in Heisenberg's inner beliefs and motivations, but he chose to close the door on discussing such issues, after receiving what he perceived as unfair rebukes.

    For me, it all comes down to a question of emotional and intellectual plausibility. Which 'plot' makes the most human sense -- Heisenberg as shallow, self-interested, incompetent, venal Nazi bureaucrat? -- or Heisenberg as an heroic, solitary, tortured visionary? Each version of history has problems, but look at the stature and reputation of this man before the war. He was larger than life. I hate to see him made so small in today's debate.
