Exhibition recalls zoo wardens who hid dozens of Jews

It was World War II, Warsaw was under German occupation, and the wife of the director of the Warsaw zoo spotted troops approaching the white stucco villa that she and her family inhabited on the zoo grounds.

According to plan, she went straight to her piano and began to play a lively tune from an operetta by Jacques Offenbach, a signal to Jews being sheltered in the house that they should be quiet and not leave their hiding places.

That scenario, repeated over years of war, was one of the tricks that allowed Jan and Antonina Zabinski to save the lives of dozens of Jews, a dramatic chapter in Poland's wartime drama that was virtually unknown until an American author, Diane Ackerman, published a book about the couple in 2007 called The Zookeeper's Wife.
