Link here - 'Unknown facts from Mieczyslaw Wajnberg's biography'
Gwizdalanka will be well-known to Shostakovich fans - she has authored several books on his life and music. She is also married to the composer Krzysztof Meyer, who has himself written widely on Shostakovich. Both of them have also written on Weinberg's music - Meyer has spoken often about his respect for Weinberg, while Gwizdalanka is the author of the Polish-language book Mieczysław Wajnberg: kompozytor z trzech światów [Mieczysław Wajnberg: Composer of three worlds]. Her book is an excellent introduction to Weinberg's biography and it documents several new discoveries on Gwizdalanka's part - new evidence that is included in this culture.pl article.
Her book also catalogues the various discrepancies between spellings of his name - see my article here on the same topic. To summarise, the 'Wajnberg' option appears to be becoming more and more compelling the deeper I dig.

All of this is certainly extremely interesting (though I am perhaps tempted to conclude that Weinberg lied about his age in order to join the Warsaw conservatoire - especially since he celebrated his birthday on the 8 December date throughout his life).
Whatever you think of these documents, and the 'Wajnberg' spelling (I find myself increasingly tempted), Gwizdalanka's article certainly provides great food for thought.
