40 Like Dr Kurt Schilling, who sought to develop a malaria serum in Dachau by experimenting on prisoners; see Gilbert, Nuremberg Diary. Moreover, this research was part of that far-reaching endeavour to build a 'special SS science'; see Mitscherlich and Mielke, Doctors of Infamy. Mention here must also be made of the so-called Freundeskreis Himmler, a gathering of predominantly industrial patrons of the SS. Several members of this circle apparently passed on to Himmler and the quacks who surrounded him a few concrete suggestions in consideration of the fact that human research in the concentration camps presented an unrivalled opportunity to shorten protracted and costly tests; see Mitscherlich and Mielke, Doctors; also the analytically cliche-ridden but factually informative article by Klaus Drobisch, 'Der Freundeskreis Himmler. Ein Beispiel fur die Unterordnung der Nazipartei und des faschistischen Staatsapparats durch die Finanzoligarchie', Zeitschrift für Geschichtswissenchaft, No. 2 (East Berlin, 1960).
