Scope and Content

1942 August 16, letter from Lorenz Janowski to his wife, Johanna Janowksi with secret note.

Context

Although mail between concentration camp prisoners and their families was limited to one or two letters or cards per month each way, and Nazi censors checked all incoming and outgoing mail, some inmates occasionally managed to slip secret messages past the censors, risking severe punishment. Lorenz Janowski concealed a note to his wife beneath a pair of 6-pfennig stamps on this August 16, 1942, letter. Written in Polish, the secret message acknowledged receipt of clothing and asked for bread. The normal letter inside, written in German as required, contained only the permissible platitudes. Prisoners were allowed to request parcels from their loved ones, but they were not permitted to request specific items.
