I'm researching about the presence of important scientists in Nordic Countries (Iceland, Norway, Denmark, Sweden and Finland).
I was hoping that someone could help me since I've not been able to find relevant information.
It is well known that Eugene Paul Wigner had to travel to Stockholm, Sweden, to receive his Nobel Prize. I thought that he also travelled to Copenhagen (mainly to discuss Quantum Models with Niels Bohr, like many scientists at the time did, like Paul Dirac, Albert Einstein or John Wheeler) I'm pretty convinced that he travelled at least once to Denmark...But I did not find anything...So, maybe someone here knows more about this...
Also, I have not found any information that says that Wigner travelled at least once to Norway or Finland (I honestly don't think that any scientist at that time travelled to Iceland, so I'm going to ignore this country)...
Finally, I have not found any information that says that John von Neumann travelled at least once to any nordic country...But again, this is weird for me...Didn't he at least go once to Copenhagen?
So did they travelled to any Nordic Countries? Didn't they give conferences, for example, at these countries at least once in their lifes?
Thank you for your help in advance!
