Documents of the Racial Hygiene Research Unit (RHF) in the Federal Archives in Koblenz, Germany, September 1981. After 1945, the files described by survivors as ‘planning documents for the genocide’ continued to be used by former employees of the RHF. After the Association of German Sinti learned of their existence and the Federal Archives did not take any action, 18 Sinti occupied the archives of the University of Tübingen on 1 September 1981 and managed to have the documents removed to the Federal Archives on the same day.
The collection includes thousands of personal names, index cards, survey documents, registration data, family trees and photographs—testimonies and pieces of evidence that were withheld from the survivors for decades in order to enforce their claims for recognition and compensation.
