Returned to the owner

Since the creation of the Origins Unknown Agency (Bureau Herkomst Gezocht), nearly 500 works of art have been returned to rightful claimants at the advice of the Restitutions Committee. These restitutions were preceded by detailed research of the records of the Netherlands Art Property Foundation (SNK – Stichting Nederlands Kunstbezit). Some claims which were made immediately after the Second World War turned out to have been unjustly rejected by the SNK. Claimants were also often unable to pay the money they had received as a result of forced sale back to the Dutch state. Using the name of the previous owner listed on these claims as a point of departure, the search could begin. Research of the SNK records also revealed entirely new information about potential rightful claimants. First, it had to be determined whether these individuals had survived the war and/or whether any of their direct heirs were able to be located. An exhaustive search for previous rightful claimants and their heirs was launched. Civil status registers and population registers, telephone books from all over the world, notarial archives and tax archives were carefully examined. For a number of difficult cases, this phase of the research is still in full swing. Considering all the restitutions that have been made, it is clear that this enormous amount of work has not been in vain.

In August 1946, a shipment of jewelled, gold and silver objects containing a silver kiddush cup with a Hebrew inscription returned to the Netherlands. There were some signs which may have helped to clear up the shipment's provenance, but nothing happened. Until recently, the cup remained part of the NK (Dutch Art Property) collection. During the preparations for the Origins Unknown Agency's (Bureau Herkomst Gezocht) sixth interim report, a decision was taken to devote extra attention to the object by printing an image of it in colour. In doing so, the Agency was hoping to provoke a reaction. And that is exactly what happened. In October 2004, Jelka Kröger from the Jewish Historical Museum wrote a letter and published an article in the Nieuw Israelietisch Weekblad. She had done research into the correct translation of the Hebrew inscription on the cup. She discovered that the cup had been presented to Hartog Koopman by the Jewish Community of Oud-Beijerland on the occasion of his 80th birthday in 1889. Presumably, in 1940 the kiddush cup had been in the possession of his grandson, who was killed during the war. In April 2005, five heirs submitted a request for restitution. Following the Restitutions Committee's positive pronouncement, the then State Secretary of the Ministry of Education, Culture and Science resolved to return the cup.
