Karl-Otto Koch

convicted by an SS court and executed by an SS firing squad in Buchenwald in April 1945 1897–1945

Karl-Otto Koch served as first commandant of Buchenwald and Majdanek, after earlier service as commandant of Sachsenhausen. The profile reconstructs the person’s function in Buchenwald in Germany and Majdanek in occupied Poland through documented office, decisions, supervision or operational conduct. It does not assign every crime committed by an institution or region to one individual.

Crimes against humanity

Confirmed findings

Koch commanded Sachsenhausen in 1936, became the first commandant of Buchenwald in 1937 and the first commandant of Majdanek in 1941.
Under his command, camp rule included starvation, forced labour, beatings, torture and executions.
An internal SS investigation charged him with embezzlement and the murder of prisoners who could expose his offences.

Place in the chain of responsibility

As commandant, Koch helped establish and enforce the camp regimes through which imprisonment, exploitation and lethal violence were organised. The profile does not attribute every death over the full histories of Buchenwald and Majdanek to his command periods.

Key events and mechanisms

On 1 August 1937 he became the first commandant of Buchenwald.
From September 1941 to August 1942 he served as the first commandant of Majdanek.
On 5 April 1945 he was shot in Buchenwald following conviction by an SS court.

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

Koch never faced an Allied court. The SS tried and executed him before the end of the war, principally in connection with corruption, embezzlement and unauthorised murders rather than for the camp system's crimes against its prisoners as such.

Limits of the evidence

Some biographical details differ between secondary accounts. Figures for all victims of Buchenwald and Majdanek cover periods beyond Koch's command and cannot be used as a personal victim total.
