Rudi Ekkart

Ekkart was born in The Hague on 23 December 1947.^[1] He studied art history and archaeology at Leiden University.^[1][2] In 1997, he received his doctorate from the University of Amsterdam with the dissertation Portrettisten en portretten: studies over portretkunst in Holland, 1575–1650, supervised by Ernst van de Wetering.^[1][3]

After his studies, Ekkart worked at the Academisch Historisch Museum in Leiden and at the Rijksmuseum Meermanno-Westreenianum / Museum van het Boek in The Hague.^[2][3] He joined the Netherlands Institute for Art History as deputy director in 1987 and became director in 1990, leading the RKD until his retirement in 2012.^[2][4]

In 2004, Ekkart was appointed professor of methodological aspects of art-historical documentation at Utrecht University, a chair that reflected the RKD's central role in attribution, documentation, image archives, and the research infrastructure of Dutch art history.^[1][5] His inaugural lecture, delivered in 2005, was titled Kwesties van vraag en antwoord.^[1]

Ekkart also served on numerous Dutch and international cultural, scholarly, and museum boards, including bodies connected with art-historical publishing, museum policy, digital heritage, university collections, the Mondriaan Foundation, the Vereniging Rembrandt, and the Research Institutes in the History of Art.^[1][2]

Ekkart's scholarship has centered on portraiture in the Low Countries, with particular attention to attribution, likeness, inscriptions, social function, and the documentary value of portraits as historical evidence. His dissertation examined portrait painters and portraiture in Holland from 1575 to 1650, a period central to the development of portraiture before and during the Dutch Golden Age.^[1][3]

With Quentin Buvelot, Ekkart co-authored Dutch Portraits: The Age of Rembrandt and Frans Hals, published in connection with the 2007–2008 exhibition at the National Gallery in London and the Mauritshuis in The Hague.^[6][7] The exhibition brought together sixty-six examples of seventeenth-century Dutch portraiture and was reviewed as one of several major studies that expanded scholarly attention to Dutch portraiture as a distinct historical and artistic field.^[8]

He has also published on individual portraitists and draftsmen, including Johannes Thopas, the seventeenth-century deaf draughtsman whose portrait drawings were the subject of Ekkart's study Deaf, Dumb and Brilliant: Johannes Thopas, Master Draughtsman.^[9] CODART lists his later publications on subjects including Rembrandt's portrait commissions, Govert Flinck, Ferdinand Bol, Aert Schouman, and Johann Friedrich August Tischbein, showing the range of his work across portraiture, court culture, museum catalogues, and exhibition scholarship.^[10]

In 2012, the Dordrechts Museum, in collaboration with the RKD, organized Portret in portret in de Nederlandse kunst in honor of Ekkart's retirement from the RKD. CODART described Ekkart as a prominent specialist in portraiture and identified Dutch portraiture from the sixteenth century to the present as his central field of study.^[4]

Ekkart has been a central figure in Dutch provenance research concerning artworks looted, confiscated, sold under duress, or displaced during the Second World War. From 1997 to 2004, he chaired the Origins Unknown Committee, widely known as the Ekkart Committee, which supervised research into the provenance of the Netherlands Art Property Collection, or NK Collection.^[3][11] The NK Collection consisted of roughly 4,000 objects, including paintings, works on paper, furniture, ceramics, and other objects that had been confiscated during the war, recovered from Germany, and remained in Dutch state custody.^[3][11]

The Ekkart Committee also investigated the postwar work of the Netherlands Art Property Foundation, or Stichting Nederlands Kunstbezit (SNK), which had been responsible between 1945 and 1952 for the recovery and restitution of cultural property.^[11][3] Its recommendations helped reshape Dutch restitution policy by urging systematic provenance research, claimant-sensitive standards of evidence, and a broader understanding of forced sales by Jewish owners during the Nazi period.^[12]

The committee recommended that sales by Jewish private persons in the Netherlands from 10 May 1940 onward be treated as forced sales unless express evidence showed otherwise, and that claimants receive the benefit of the doubt where the wartime record was incomplete. One of its recommendations concerned the establishment of a separate Restitutions Committee to handle individual restitution requests; the Dutch Restitutions Committee was established in late 2001.^[3][13] Later restitution cases continued to cite the Ekkart Committee's recommendations, including its standard that title to a claimed work could be accepted when proved with a high degree of probability and without indications to the contrary.^[14]

Ekkart later chaired the independent supervisory committee overseeing renewed provenance research into NK Collection objects at the Cultural Heritage Agency of the Netherlands. The agency described the committee's role as monitoring the quality of past and future provenance research and assessing whether research standards were sufficient to determine object histories as accurately as possible.^[3]

In 2023, Ekkart and Eelke Muller published Looted Art & Restitution: The Exodus and Partial Return of Dutch Art Property During and After World War II, a study of the wartime removal, postwar recovery, and partial restitution of Dutch art property.^[15][16]

Ekkart's work also extended into the field of art authentication, where questions of attribution, documentation, provenance, technical research, and legal responsibility converge. In 2012, he and Milko den Leeuw founded the Authentication in Art Foundation, which brought together specialists from art history, conservation, material science, the art market, and art law to address developments in authentication practice.^[17]

In 2023, Ekkart was made an honorary member of the Association for Dutch Art Historians.^[18]
