Abraham Gordon, a good Jew from Poland, has a favorite Christmas tradition. Each year on Dec. 25 he tells the story of the cast iron stove. It’s a tale with a happy ending — about the family that saved Gordon and his family from the Nazis.On Christmas Eve, 1943, the youngest son in the Ziemczonek family — Catholics who lived on a farm in the part of Poland that became Byelorussia in 1939 — carried the heavy stove to the cave in the forest where the Gordons were hiding.
