Aside from discussing the emergence of the neutron and the neutrino, which resolved important questions about the atom and changed the face of physics forever, they were also entertained by a theatrical parody of Goethe's Faust. One of them caricatured Paul Ehrenfest as Faust, another Niels Bohr as the Lord, a third Wolfgang Pauli as Mephisto, etc., and a Danish woman played a neutrino as Gretchen.
In the late 1920s and early 30s, Germany was no longer associated as strongly with the Kaiser-era imperialist and jingoist tendencies that undermined the moral stature of the German scientific communities during World War I.
(Scientists like Fritz Haber, Ernst Haeckl, Max Planck, and Wilhelm Roentgen, composer Engelbert Humperdinck, artist Max Liebermann, and literary figures like Gerhart Hauptmann, signed a 1914 letter proclaiming amongst other things, in a mischaracterization of the invasion of Belgium, that:
It is not true that our troops treated Louvain brutally. Furious inhabitants having treacherously fallen upon them in their quarters, our troops with aching hearts were obliged to fire a part of the town as a punishment. The greatest part of Louvain has been preserved. The famous Town Hall stands quite intact; for at great self-sacrifice our soldiers saved it from destruction by the flames.("Manifesto of the Ninety-Three" [Wikipedia] (Retrieved September 19, 2019))
Gino Segrè, a physicist who worked at CERN and Berkeley and taught at the University of Pennsylvania, has written a book about the Copenhagen Conferences and physicists' progress in and around 1932, that 'year of miracles': Faust in Copenhagen (2007).
Bohr and Bohr's guests face almost no adverse judgment from Segrè's pen, in my opinion.
I don't know if the author was forbearing because he reveres these figures so greatly — his physicist uncle also met and knew a few of them; or because he is a rarely optimistic critic of human nature. Or perhaps he was worried about receiving angry reactions, or about betraying the understandings on the basis of which he obtained his material.
