Dissolve my Nobel Prize! Fast!

Dissolve my Nobel Prize! Fast! It's 1940. The Nazis have taken Copenhagen. They are literally marching through the streets, and physicist Niels Bohr has just hours, maybe minutes, to make two Nobel Prize medals disappear.
What a cool story. Thanks for posting this.

With the passing of Dr. Ralph Steinman, it may inspire some perspective to know that not even coinage metals are permanent fixtures relative to the long arc of Science.

Perhaps. It took a chemist to save the day though. Dissolving them in aqua regia is easy enough. Getting the gold back to the committee to recast the medals after the war was a neat trick.

But chemistry is so much more awesome than magic! Because it's real. And because you can do things like dissolving gold before the Nazis get it and then recreating it afterward.

He doesn't say specifically, but there are a number of ways to do it. You need to do a couple of things: first remove the nitric acid to prevent redissolution, then reduce the gold back to metallic form, finally remove the other impurities. Here's a sketch of one possible route; this is a more detailled version.

So this is actually kind of tricky to explain, and not a super-simple thing if you're working on, say, half-remembered high school chemistry. But the principle is simple enough: The atoms are still there. Molecules are just arrangements of atoms; water is a bonding of oxygen with hydrogen at a 1:2 ratio, but if you zap it the right way (literally, I mean; electrolysis is the name of the process and that electro part is just what you think) you can separate them and end up with oxygen bonding to other oxygen, and hydrogen doing the same thing. It's a lot more complicated than that for getting the gold back out of the gold-plus-aqua-regia, but it's the same basic principle: The Stuff is there, just bonded differently than the combination we think of as "shiny special gold."
To use a weird analogy, you can build a house out of bricks and wood, or take it all apart and rearrange them into a gazebo and a brick firepit. Same bricks, same wood, but different arrangement that works very differently.

Shortly before this my Morfar was down at the border, I guess somewhere in Sønderjylland, in the Danish army. He told me that they shot at the radiators on the trucks, but tried not to shoot directly at the Germans because they didn't want to make them mad. I guess by the time the Nazis were in Copenhagen he was being marched to internment accommodations, but from what he tells me they didn't have it that tough. But he hated Germans, especially Germans around his own age and older, right up to his death.

Niels Bohr slow-walked the development of nuclear weapons throughout the war, such that the Nazis never actually got them. We owe him a great debt of gratitude for that. The business with the medals is nice but it's nowhere near as important as this.

...When the Nazis ransacked Bohr's institute, they scoured the building for loot or evidence of wrongdoing but left the beaker of orange aqua regia untouched. Hevesy was forced to flee to Stockholm in 1943, but when he returned to his battered laboratory after V-E Day, he found the innocuous beaker undisturbed on a shelf.
Why was it not disturbed by the Nazis, or anyone else for four or five years? Because it looked like a beaker full of pee, that's why.

Bohr got out and worked on the Manhattan Project, and, it's to be presumed, did not slow-walk the development of nuclear weapons. You're thinking of Heisenberg. It's been proposed, but, so far as I know, we don't know for sure, that he deliberately stymied progress on the Germans' bomb project.

Not only did Bohr work on the Manhattan Project, he struck up a friendship with Feynman because Feynman was the only one who would argue with him
Per Wikipedia
Feynman was sought out by physicist Niels Bohr for one-on-one discussions. He later discovered the reason: most physicists were too in awe of Bohr to argue with him. Feynman had no such inhibitions, vigorously pointing out anything he considered to be flawed in Bohr's thinking. Feynman said he felt as much respect for Bohr as anyone else, but once anyone got him talking about physics, he would become so focused he forgot about social niceties.

My understanding, from an Oppenheimer biography I read some time ago, is that by the time Bohr got to Los Alamos most of the physics related to the uranium and plutonium fission bombs was settled. Mostly what he did is act as a physics devils advocate (pushing scientists to think beyond the project) and to spur discussion of moral/ethical problems.
So his ability to "slow-walk" the American project would have been quite limited, even if he wanted to.
Of course, I could be misremembering things. It's been awhile since I cracked that one open.

OK, but does this then count as a collaboration for purposes of calculating a given physicist's Einstein Number? And does Bohr count as a collaborator or contributor?

Huh? From your own link: "The Soviet Union and Nazi Germany signed the Molotov–Ribbentrop Pact in August 1939. The pact was nominally a non-aggression treaty, but it included a secret protocol in which the Eastern European countries were divided into spheres of interest. Finland fell into the Soviet sphere."
The Winter War was very much an arm of WWII.

Another great moment in covert chemist genius: Herman Mark's coat hangers.
In early 1938 Mark began preparing to leave Austria by delegating his administrative duties to colleagues. At the same time he clandestinely started to buy platinum wire, worth roughly $50,000, which he bent into coat hangers while his wife knitted covers so that the hangers could be taken out of the country.
