Note to the electronic edition: Address Unknown first appeared in 1938 in the literary magazine Story. The foreword below appeared in its first separate book publication the following year. Curiously, although the story remains popular in French, German, and other languages, the original has largely been forgotten in the United States, as has the author, Kathrine Kressmann Taylor (1903-1997), who suppressed her first name when Address Unknown was first published in deference to the common prejudice against woman writers who chose “masculine” themes and genres. Although one can quibble with historical details, the story is surprisingly accurate for its time in its portrayal of the fate of Jews in the Third Reich.
