Research possibilities

Hadamar Memorial Museum offers various possibilities to conduct research.
This includes, in particular, the digital data base of persons in which almost all of the approximately 15,000 “euthanasia” victims who were murdered at the Hadamar killing centre between 1941 and 1945 are recorded by name.

The database collects information about the individual victims of the Nazi “euthanasia” crimes. However, not all information is available for all persons.
The database serves as a basis for providing information to the relatives of victims, but also to researchers.

We generally carry out the search for you using the database. However, if your inquiries are too extensive, we ask that you come to the Memorial Museum and carry this research out yourself. As a general rule, you can conduct research using the database on-site.

In addition to the database of persons murdered, you can use our archive, collection and documentation to conduct your own research or make inquiries on various areas of investigation. These areas include the following main topics:

  • any research into persons murdered in Hadamar
  • patients of the pre-war and post-war period
  • staff (including perpetrators)
  • foundation and development of the Memorial Museum
  • source material (photos and documents) for publications
  • The estate (Nachlass) of Ernst Klee
  • history of the institution

Conducting research at the Memorial Museum is free of charge. The relevant data protection regulations must be observed.

For all inquiries, please use our online contact form.

Support for relatives

People of all generations are increasingly turning to Hadamar Memorial Museum and requesting information about the fate of their relatives. Since communication in writing can only be concise and usually raises more questions than it answers, the Memorial Museum offers relatives the opportunity to meet and discuss the matter in person.
During these meetings, relatives learn about the circumstances surrounding the death of their relatives and have the opportunity to ask specific questions. Relatives often bring copies of documents and photos to the meeting, so that a face can be put to the victims’ names and life stories may emerge from the individual lines in the database.

Should you decide to offer originals or copies to Hadamar Memorial Museum after consulting with your family members, we would very much appreciate this. This would enable us to preserve these documents permanently and also make them available for academic research into the Nazi “euthanasia” crimes.
