In May 2005, an application for restitution was filed with the Restitutions Committee regarding a rather unique object, namely a silver Kiddush cup with Hebrew inscription that was part of the Netherlands Art Property Collection (NK 3519). The cup is shown on the cover. In the Jewish tradition, the word Kiddush – which literally means consecration – refers to the blessing of a glass or goblet of wine at the beginning and end of the Sabbath and other holy days and ceremonies. According to the Origins Unknown Agency, the cup may have belonged to the applicant’s great-grandfather. The Restitutions Committee gave priority to this application for restitution because of the applicant’s advanced age. The applicant also acted on behalf of four other descendants of his great-grandfather.
The investigation showed that the cup had been part of a shipment of gold and silver jewellery and other objects that was returned to the Netherlands in 1946 and that were known to have been looted from Dutch prisoners, particularly Jews, during the war. The cup had been included in the Netherlands Art Property Collection though the meaning of the inscription had not been looked into before. At the end of December 2004, in response to a publication containing an illustration of the cup in a sub-report of the Origins Unknown Agency, an employee of the Jewish Historical Museum in Amsterdam conducted a study of the Kiddush cup and the inscription. The inscription was translated as follows:
—- The holy congregation of Oud-Beijerland
To the beloved Mr Zwi, son of Mr Uri
—on his eightieth birthday
—-Niesan [5]649 (=1889)
In the light of this, the employee reached the following conclusion. In Jewish circles, the name Zwi is also rendered as Hartog, while the name Uri translates as Philip. Hartog Koopman Sr. was the son of Philip Koopman and celebrated his 80th birthday in April 1889. He was a prominent member of the Jewish Community of Oud-Beijerland and a well-known tradesman in the village. He had also presented the Jewish Community with several synagogal objects. In all probability, Hartog Koopman Sr. was the person known in the Jewish community of Oud-Beijerland as Zwi, son of Uri, and he had received the claimed object from the Jewish Community of Oud-Beijerland in April 1889 as a token of appreciation.
The Committee took up this conclusion and considered Hartog Koopman Sr. the first owner of the Kiddush cup. The investigation did not reveal with any certainty, however, which of his twelve children inherited the cup on Hartog Koopman Sr.’s death in 1892. As to who owned the cup in 1940, a matter of importance with regard to the possible restitution, the investigation found no unequivocal proof either. As the applicant suggested in his application, this might have been the grandson of Hartog Koopman Sr., known as Hartog Koopman Jr., who perished in Sobibor in 1943 together with his wife and three children. In any event, the Committee considered it plausible that because Kiddush cups are considered family heirlooms, this cup was passed on within the family. The Committee decided to leave the question which of the children owned the cup in 1942 unanswered and to allow the application for restitution on behalf of all Hartog Koopman Sr.’s heirs. Moreover, the Committee concluded that it was plausible that the family’s loss of possession of the cup had been of an involuntary nature, being a result of persecution by the Nazi regime.
In its meeting of 3 April 2006, the Committee recommended that the Kiddush cup be returned to the applicant and the parties on whose behalf the claim had been submitted, for the benefit of the heirs of Hartog Koopman Sr. In a decision taken on 23 May 2006, and supplemented by a further decision on 13 November 2006, the State Secretary adopted the recommendation.
