Debunking the myth of Nazi mosquito-borne biological weapons

Starting at the end of January, several press items reported on an academic article published in the December edition of the quarterly magazine Endeavour. Based on documents from the Dachau concentration camp, Dr Klaus Reinhardt, a biologist at the University of Tübingen uncovered that Nazi scientists wanted to use mosquitos as insect vector for the delivery of malaria plasmodium protozoans. According to the article abstract:

In January 1942, Heinrich Himmler, head of the Schutzstaffel (SS) and police in Nazi Germany, ordered the creation of an entomological institute to study the physiology and control of insects that inflict harm to humans. Founded in the grounds of the concentration camp at Dachau, it has been the focus of previous research, notably into the question of whether it was involved in biological warfare research. This article examines research protocols by the appointed leader Eduard May, presented here for the first time, which confirm the existence of an offensive biological warfare research programme in Nazi Germany.

In 1999, while at SIPRI, I oversaw the publication of a volume in the Chemical & Biological Warfare Studies series edited by Erhard Geissler and John Ellis van Courtland Moon on Biological and Toxin Weapons: Research, Development and Use from the Middle Ages to 1945. Geissler, now a retired professor in molecular biology and genetics, wrote the chapter on Germany’s biological warfare programmes before and during World War 2. He basically debunked the myth that the SS was conducting a secret offensive biological warfare programme against Hitler’s explicit orders not to investigate such weapons.

Reinhardt claims to have recently uncovered fresh documents from Dachau and suggests that the earlier assessments of Germany’s offensive BW activities are wrong. Being familiar with Geissler’s investigations — particularly with the 900-page mastodont, emphatically entitled Biologische Waffen – nicht in Hitlers Arsenalen — and other historical research on the origins of offensive biological warfare programmes on the eve of and during World War 2, I was mildly sceptical of the new claims. While the possibility of finding new archival material always exists, contradicting a central conclusion of extensive historical research is quite a different matter. An article in National Geographic summarised Reinhardt’s findings, but also noted that they are controversial among researchers. His conclusions were therefore not as absolute as some press items were suggesting, I therefore assumed.

Yesterday, however, Erhard Geissler posted a blog commentary, calling the findings ‘disinformation’ :

Despite the thrilling headline Reinhardt in his article does not provide any new material regarding the dual-use activities performed in the Entomological Institute of the Waffen-SS beyond that what was already published. The low-scale experiments performed by Eduard May in September 1944 on the survival of food-deprived mosquitoes, can hardly assessed as confirmation of “the existence of an offensive biological warfare research programme in Nazi Germany”. Besides that, the main body of Reinhardts paper including its concluding paragraph does not pick up the alleged BW preparations but deals with the “enigmatic figure” of its director, Eduard May.

Geissler concludes:

Up to today there is no evidence of offensive biological warfare research in Germany after the unsuccessful attempts of German biosabotage in WWI. It is a pitty that the misleading heading of Reinhardt ‘s article similar to other disinformation campaigns are favored by some media’s apparent craving for a breaking story that often supersedes thorough investigation.

This is pretty categorical debunking of research findings. To be continued?
