Thank you for the additional research. I may go over to the German Wikipedia and the Russian to see their versions of the same event.
Often different Wikipedias have VERY different accounts of the same issues; but because people tend to stick to their own native language Wikipedias, they never see it.
[most notably, the German Wikipedia has LOTS of extra information on certain scientists I’d found interesting in the past, filling in a lot of knowledge gaps that are resolved in German but are absent in English ]
