Martin Luther at the Foreign Office.
Heydrich refers to Luther as “Parteigenosse” (Party comrade).
Luther is thus a member of the Nazi Party.
His office is on Rauchstraße in the Tiergarten district of Berlin. However, the letter is addressed to the official postal address of the Foreign Office, on Wilhelmstrasse, which is within the Berlin postal district W(est) 8.
