This thought provoking and poignant story was written on the eve of the Holocaust as a series of letters between an American Jew living in San Francisco and his former business partner and friend who returned to his native Germany. Address Unknown caused a sensation when it was first published in 1938 by exposing early on the poison of Nazism. The significant and timeless message of Address Unknown speaks to our moral conscience and survives as a searing reminder that history can repeat itself.
