David Pastel was a Polish Jew who went to France before the War II. He survived Auschwitz but was murdered in January 1945 in a death march. The local priest, who buried the dead in a mass grave, didn’t know the victims’ names, asked his assistant to register the numbers tattooed on their arms. The numbers were later put on gravestones. A Holocaust researcher interested in documenting Pastel’s fate would have to go to four archives in four different countries to collect the information. At Yad Vashem: a document on which Aharon Pastel, David’s son who survived the Holocaust, registered information as well as a photograph of father and son. The document expelling him to Auschwitz is at the International Tracing Service at Bad Arolsen, Germany, where researchers will also find a photograph of Pastel during a Passover seder at the camp, etc. But now a new European Union project aims to create a unified network of Holocaust archives to make it easier for researchers and the public to find information.
