Raoul Wallenberg was a Swedish humanitarian, who in 1944 travelled to Budapest to organise a rescue program for Hungarian Jews.
He issued them with "protective passports" stating they were Swedish subjects awaiting repatriation. Although not legal, these documents looked sufficiantly official to bluff the authorities.
On one occasion he boarded a train bound for Auschwitz & handed out these passports to everyone he could. When he ran out of them he demanded the release of all who held them & escorted those freed past dumbfounded guards to safety.
Ironically, when Soviet forces entered Budapest, Wallenberg was arrested on suspicion of being a U.S. spy. He was imprisoned in Lubyanka prison, & it is probable he was executed there in 1947. However, some reports suggest he may have survived in custody until as recently as 1987.
His efforts helped save the lives of tens of thousands of Jewish people, yet until I stumbled upon this statue, I'd never even heard about him.
