BTW
What I say about Irina Sender, also applies to Wallenberg , Sugihara, Schindler members of Zegota and anyone else who saved even one jew at great personal risk.
Irina Sender had a long life and lived to 99 and almost nobody had heard of her until recently and I bet almost nobody has heard of Zegota (many of its members were tortured and killed for trying to save jews)
