Friedrich Mennecke

sentenced to death in a judgment that did not become final; died in prison before his appeal was heard 1904–1947

Friedrich Mennecke served as director of the Eichberg institution, T4 medical assessor and travelling physician who selected prisoners under Aktion 14f13. The profile reconstructs the person’s function in Germany / concentration-camp system through documented office, decisions, supervision or operational conduct. It does not assign every crime committed by an institution or region to one individual.

Confirmed findings

  • As director of the Eichberg institution he helped shape its participation in the system for murdering patients, while also working as a T4 assessor.
  • He travelled to psychiatric institutions and concentration camps where, on the basis of forms and brief examinations, he selected thousands of patients and prisoners for death in T4 killing centres.
  • In a letter of 25 November 1941 he described his own pace and routine of selection at Buchenwald; this perpetrator document makes it possible to individualise his actions in Aktion 14f13.
  • Frankfurt am Main Regional Court sentenced him to death in the Eichberg Trial in 1946. Mennecke appealed and died in Butzbach Prison before the appeal was heard, so the judgment never became final.

Place in the chain of responsibility

Mennecke connects the local direction of a psychiatric institution with the supraregional, itinerant selection mechanism of T4 and 14f13. His surviving letters make it possible to describe not merely his position but his own working methods.

Key events and mechanisms

  • taking charge of the Eichberg institution in 1939
  • beginning work as a T4 medical assessor in 1940
  • selections of concentration-camp prisoners under Aktion 14f13 in 1941–1942
  • the non-final death sentence in the Eichberg Trial in 1946 and death before the appeal was heard on 28 January 1947
No victim-count ranking

The circle records authority, function and agency. Several profiles may describe different parts of the same persecution chain, so profile-level totals must not be added together.

Postwar accountability

In the first Eichberg Trial before Frankfurt am Main Regional Court, he was sentenced to death in 1946. He appealed, but died in Butzbach Prison on 28 January 1947 before it was heard; the judgment never became final.

Limits of the evidence

Institutional sources refer to thousands of people selected by Mennecke, but do not provide one uncontested personal total. Figures for Aktion 14f13 as a whole must not be transferred to his account. Accounts of the cause of his death in prison diverge, so the profile should not decide the point without medical records.
