Berlin - Over 300 tissue samples from people killed by the Nazi regime and kept by a Berlin doctor will be laid to rest in a ceremony in Berlin on May 13, 74 years after the end of World War Two, Bild am Sonntag newspaper reported on Sunday.

The tiny samples were discovered in 2016 in the estate of anatomy professor Hermann Stieve from the University of Berlin, who had received the bodies of German anti-Nazi fighters for dissection, sometimes just minutes after they were killed at the Berlin-Ploetzensee prison.

Stieve, who died of a stroke in 1952, dissected the bodies of the mostly female victims for his research and then had them cremated and interred, sometimes in mass graves.

The samples - most less than a millimeter long - were found in small black boxes, and some were labeled with the names of the victims, Bild am Sonntag reported.

They were found in Stieve’s estate by his heirs and given to Berlin’s Charite hospital, which commissioned a study by Johannes Tuchel, director of the Berlin-based Memorial to the German Resistance, a copy of which was obtained by Bild.

“We have discovered that (Stieve) systematically aided the (Nazi) Reich Justice Ministry in obliterating the tracks of these criminal acts,” Tuchel told the newspaper. Read more at Reuters
