Krakow Forensic Institute
In response to the Leuchter Report, the Auschwitz State Museum in 1990
commissioned the Krakow Forensic Institute to carry out an investigation of the
alleged gassing sites at the camp. The result of the testing of brick and mortar samples
fully corroborated the findings of Leuchter: the Institute found either no traces or
extremely small traces of cyanide in its samples. The Institute explained the test
results, however, by stating that it could not be assumed that cyanide traces would still
be detected after 45 years of being subjected to the weather and the elements. The
Krakow Forensic Institute also tested samples of hair from the Auschwitz Museum for
cyanide. The tests proved negative. (For a copy of the report and commentary, see
"An Official Polish Report on the Auschwitz 'Gas Chambers'", Journal of Historical
Review, vol. 11, pp. 207- 216).
