In post-war interviews, she refrained from answering questions about Himmler's involvement in war crimes committed by the Nazis or about her own knowledge of them.

[1] Through Kurt Baron von Schröder, one of the founders of the Freundeskreis der Wirtschaft ("Circle of Friends of the Economy"), she met Reichsführer-SS Heinrich Himmler.

[1] That same year, Himmler borrowed 80,000 Reichsmarks from the Nazi Party Chancellery and had a house built for Potthast near Berchtesgaden in the small picturesque city of Schönau am Königssee.

[1] It remains unclear how much, if anything, either Potthast or Himmler's wife knew about his "secret work"—i.e., his involvement in the Final Solution, the genocide of the Jews.

[1] Potthast's relationship with Himmler ended in early 1945;[6] they met for the last time in mid-March 1945, after which they shared daily telephone calls until 19 April 1945.

[7] When World War II in Europe ended, Potthast was in Achensee, Austria, and, after having learned of the death of Himmler on the radio on 23 May 1945, went into hiding, living temporarily with Eleonore Pohl in Rosenheim, Upper Bavaria.

[9] In a 1987 interview with former Der Spiegel editor Peter-Ferdinand Koch, Potthast remained silent about Himmler's responsibility for Nazi war crimes.
