Sachsenhausen appears in the book’s postwar account of Fritz Pfeffer’s fate, not as a setting described through Anne Frank’s diary. The record says Pfeffer died at Neuengamme after being transferred there from either Sachsenhausen or Buchenwald, leaving Sachsenhausen as one possible stop in an otherwise incompletely documented final journey.

Identification in the Postwar Account

The reference occurs in the book’s concluding biographical information about those who hid in the Secret Annex. It identifies Pfeffer—known in Anne Frank’s diary as Albert Dussel—as having died at Neuengamme on December 20, 1944. The account names Sachsenhausen alongside Buchenwald as a possible camp from which he had been transferred, but does not resolve which one.

What the Evidence Establishes

The wording preserves a distinction between a confirmed outcome and an uncertain intermediate detail: Pfeffer’s death at Neuengamme is stated as fact, while his prior transfer from Sachsenhausen or Buchenwald is left open. The passage supplies no dates for such a transfer and no further information about Pfeffer’s time at Sachsenhausen. It therefore does not support treating his confinement there as certain.

Place in the Diary’s Documentary Frame

Sachsenhausen is mentioned in the introductory and concluding material surrounding the diary, rather than as part of a narrated episode in Anne’s entries. That framing matters: the diary records events from the perspective of a person in hiding, while the postwar account adds information about what happened to the Annex residents after their arrest. In this brief reference, the camp name marks the limits of that later reconstruction as much as it identifies a possible point in Pfeffer’s deportation history.
