The Zookeeper's Wife is a non-fiction book written by the poet and naturalist Diane Ackerman. Drawing on the diary of Antonina Żabińska, unpublished in English (though published in Polish in 1968), it recounts the true story of how Antonina and her husband, Jan Żabiński, director of the Warsaw Zoo, saved the lives of 300 Jews who had been imprisoned in the Warsaw Ghetto following the German invasion of Poland on September 1, 1939. The book was first published in 2007 by W. W. Norton.
