Some Jews survived by assuming false identities and pretending to be Christian. Anna Lipszyc assumed the name Anna Wojcik and was able to find work as a housekeeper in Stuttgart, Germany.  She was aided by Jurek, a Polish policeman, who wrote letters to Anna so that she would not arouse suspicion. Anna’s family and friends had all been taken away and murdered, so she otherwise would not have received any mail.  Jurek was himself imprisoned but he continued to write to her. Thanks to his help, Anna survived the Nazi period and was able to resume her life.
