Do you know of Maximilian Kolbe?

Go read about this man. Maximilian Kolbe
When ten prisoners at Auschwitz-Birkenau were condemned to death by starvation, Maximilian Kolbe stepped forward and said, "I am a Catholic priest from Poland; I would like to take his place, because he has a wife and children."

The man he saved? Franciszek Gajowniczek ?

He died on March 13, 1995, at Brzeg in Poland, 95 years old - and 53 years after Kolbe had saved him. But he was never to forget the ragged monk. After his release from Auschwitz, Gajowniczek spent the next five decades paying homage to Father Kolbe, honoring the man who died on his behalf.
In December 1994, the 94-year-old Pole visited St. Maximilian Kolbe Catholic Church of Houston. His translator on that trip, Chaplain Thaddeus Horbowy, said: "He told me that as long as he . . . has breath in his lungs, he would consider it his duty to tell people about the heroic act of love by Maximilian Kolbe."

The timeliness is self evident.
