Warsaw, 19 May 1947. A member of the District Commission for the Investigation of German Crimes in Warsaw, Halina Wereńko, interviewed the person named below as a witness, without an oath. Having been advised of the criminal liability for making false declarations and of the obligation to speak the truth, the witness testified as follows:

Before the war, I was employed as a secretary at the National Zoological Museum in Warsaw at Wilcza Street 64. In October 1939, I was at the museum. At the end of October or at the beginning of November, some Germans came to the museum and talked to the museum director, Jaczewski. I was not present during that conversation. The next day, a truck with German police arrived, and they took away collections from the museum. The truck came back several times.

While they were taking the collections away, I went out to the hall and saw Associate Professor Jaczewski talking to a German officer and a German dressed in civilian clothes. That German asked me if Dr. Dunajewski, a famous ornithologist (who later died in the Warsaw Uprising), was present. He also said that he had exchanged scientific letters with Dunajewski.

I don’t speak German very well, so I don’t know the details of the conversations between the Germans and Mr. Jaczewski.

I don’t know what exactly was taken away from the museum. I heard about microscopes and a bison.

I don’t remember what the Germans looked like and who took the collections, and I don’t know their names.

At this point, the report was concluded and read out.
