Jan Gebert says he is happy to offer his own bed to Ukrainians arriving in Warsaw.
Gebert is descended from Holocaust survivors, some of the few who lived through Hitler's obliteration of Warsaw's Jewish community , which was then the largest in Europe.
To not help others now is unthinkable to him, so he and his girlfriend repeatedly invite refugees to stay until they have somewhere more permanent.
He said global Jewish philanthropies, mainly in the US, have raised about $100 million to help Ukrainian refugees.
But asked what life could have been like if more of his relatives had been saved from the Nazis, he sounds almost wistful.
"If someone had helped those, my ancestors, my cousins, during the Holocaust, I will have much greater family next to me," he said.
"That would be wonderful -- to have a great big family in Warsaw, a Jewish family which survived the war, that would be the most beautiful, beautiful thing.". »
