Dachau: Polish Clergy Subjected to Infectious Experiments
Second World War; experimental operations from 1941 · Torture, maiming and killing of defenceless people
At Dachau, Polish clergy were used in experiments that induced illness. Documentation in the memorial exhibition separates malaria research from purulent-infection research, but presents the second group as part of the first. The cited testimony of Kazimierz Majdański describes prisoners being selected. Participant figures are not death figures, and Polish subsets must not be added. [1]
Editorial account based on the sources listed below. Sources checked: 5 September 2026.
- Victims and toll
- 176 Polish clergy in a group of 185 infected with malaria; from that group, 40 clergy, including 38 Poles, were subjected to phlegmon experiments. The groups are not added.
- Perpetrators
- German doctors conducting experiments and the SS camp apparatus at Dachau; the excerpts used do not identify every executor personally.
- Documented methods
- deliberate infection with malaria · inducing purulent infections · forced experiments on prisoners
Two series, two different sets
Panel 2207 of the Dachau Memorial exhibition gives 185 clergy infected with malaria, including 176 Poles. The wording '40 of them' presents the clergy subjected to phlegmon experiments as part of the first group; that subset included 38 Poles. One must therefore not add 176 and 38 or write of 214 different Polish priests. The panel used contains no lists that would independently verify this relationship by name. [1]
Selection seen by a prisoner
A neighbouring panel cites Kazimierz Majdański's account of the selection of clergy on 10 November 1942. Prisoner numbers were recorded, depriving them of influence over their later fate. This Polish survivor account is a different kind of testimony from the editorial numerical summary in the exhibition, though both are provided by the same institution. [1]
A hospital subordinated to violence
The museum history of the Dachau infirmary describes the contrast between propaganda depictions of care and the lack of medicines, neglect and use of prisoners for experiments. From 1941, experiments involving, among other things, malaria and purulent infections were carried out there. General totals of infirmary victims cover different nationalities and are not a total for Polish clergy alone. [2]
The panel gives 12 deaths in the group of 40 clergy examined in connection with phlegmon. It does not state the nationality of every person who died. We therefore do not present these 12 as an established number of Poles killed. Exposure to illness and forced intervention remain a crime also against those who survived. [1]
Limits of the findings
Panel 2207 presents 40 clergy as part of the group of 185; Polish subsets of 176 and 38 are therefore not added. This relationship was not verified against nominal lists. Numbers subjected to experiments do not mean numbers killed, and the nationality of the 12 who died is not broken down. The infirmary study supplies context, not a second national total. [1] [2]

How we assess sources
The evidence base consists primarily of Polish scholarly publications, investigative findings, archives, museums and documented witness accounts. Reliability is assessed through the document’s provenance, scholarly method and the ability to check the finding. Statements by perpetrators and family accounts of perpetrators require especially critical comparison with other material. Two pages from the same institution may repeat one finding; they are not automatically treated as independent confirmation.
