Heinrich Bütefisch (24 February 1894, Hanover – 5 September 1969, Essen) was a German chemist, manager at IG Farben, and Nazi war criminal.
As a leading figure in IG Farben, Bütefisch joined the Freunde des Reichsführer-SS, an exclusive group close to Heinrich Himmler whose membership allowed prominent individuals in German society to become effectively SS officers without undergoing rigorous selection or training.
Monowitz was built as an Arbeitslager (workcamp); it also contained an "Arbeitsausbildungslager" (Labor Education Camp) for non-Jewish prisoners perceived not up to par with German work standards.
By 1942 the new labour camp complex for IG Farben prisoners occupied about half of its projected area, the expansion was for the most part finished in the summer of 1943.
Because the factory management insisted on removing sick and exhausted prisoners from Monowitz, people incapable of continuing their work were murdered.
Summing up all figures, an estimated total number of about 10,000 Auschwitz concentration camp prisoners lost their lives because of working for IG Farben.
He was indicted at the Nuremberg IG Farben trial, convicted and sentenced to 6 years including time already served.
The reasons for the judgment contain the statement 'Die Ausbeutung der Arbeit von KZ-Insassen ist ein Verbrechen gegen die Menschlichkeit.'
