Nazi-era Provenance Gaps and Digital Analytics: A Stunning Lack of Progress

As 2019 draws to a close, one is astonished at how little digital analysis has been published concerning artworks that changed hands during the Nazi era and still have provenance gaps today.

Powerful digital tools exist. Yet they are not used by the Nazi-era art provenance research community. 

• There is no "dashboard".
• No "at-a-glance" executive summary that tells us how the different museums and institutions around the world are advancing in their provenance research projects related to the persecution of the Jews during the Nazi era. 
• No "Transparency/Opacity Index" to identify institutions that do and do not publish provenance
• No executive management tool (with goals, tasks, resources, action items and persons responsible) for ensuring that provenance information is publicly available, much less accurate.  
• No single database that brings together provenances that have already been published publicly. 
• No world map that compares the pre-1932 location of Jewish-owned artworks and their current location today.
• No digital network analysis of the art dealers, collectors, institutions, publishers, and experts who collectively managed to shift artworks once owned by Jewish collectors in Europe to other hands.
• No database of fake provenances, (and authors of fake provenances), even though "errors" in provenance texts correlate significantly with illicit transactions that a person or persons has tried concealed
• No attempt at pattern detection in the provenance texts, though tools for regression analysis and even AI are becoming mainstream

Here we are in the digital age, but only the tiniest fraction of the power of the digital tools available has been applied to the problem of the Nazi-era art market. 

The task is massive, as everyone knows. Each individual artwork can take years to research. Archives are missing, hidden, destroyed, manipulated. Access is hard to obtain. Partial. But even amid all these obstacles, there is plenty that can be done in using digital tools to gain insights from the research that already exists. 

Let 2020 be the watershed year in the use of advanced digital tools to track, expose and analyse Nazi-era art provenance gaps.

Perhaps the recent interest in the cultural heritage of colonial era transfers from Africa, Asia and other lands will infuse new energy  and more advanced digital methodologies into provenance research.

ART PROVENANCE DATASET: Origins Unknown: artworks recovered from Germany after WWII and held by the Dutch state

The Netherlands, which saw more than 75% of its Jews murdered in the Holocaust*, has created a website for "what remains of the artworks recuperated from Germany after World War II and is managed by the State". 

The Nederlands Kunstbezit collection, or NK-COLLECTION, includes around 4,700 paintings (approx. 1,600), drawings, prints, ceramics, silverware, furniture, carpets and other special art objects. The artworks are currently located in a variety of places: Dutch museums, embassies and government buildings, as well as  the Cultural Heritage Agency (RCE) depot.** 

The "Origins Unknown Agency" (Bureau Herkomst Gezocht  or "BHG")  was created in 1998, however digitisation and online publication only began in 2015. (see Origins Unknown)

Several databases are public and can be consulted, item by item. However, there is not to our knowledge at present an easy way to download all the provenance files in order to analyse them with advanced digital tools outside of Holland.

This first dataset is an attempt to facilitate access to the public provenance information published online by the Dutch authorities, and to put it in a form that will facilitate digital analysis.

Additional information provided about the provenance research project at the Albertina Museum by the Kunstdatenbank on its website:

Provenance researcher: Mag.a Julia Eßl

In the Albertina, Maren Gröning carried out provenance research for the period 1938–1960 actively between 1998 and 2000 and as required between 2000 and 2009. During this time, 49 reports regarding 317 works were submitted to the Commission for Provenance Research. Of these, 163 objects were restituted, in addition to a collection of around 3,500 posters (as at October 2009) and the restitution of a further 34 objects was recommended by the Advisory Board pursuant to the Art Restitution Law, Federal Law Gazette 1998/181.

Mag. Julia Eßl and Dr. Pia Schölnberger (until August 2017) have been working as provenance researchers at the Albertina since spring 2011, on behalf of the Commission for Provenance Research. Their task is to build on the research already carried out at an intensified level, by examining all objects which came into the collection between 1933 and the present for their origins and previous owners. In dubious or contentious cases, dossiers are compiled which are subsequently submitted to the Art Restitution Advisory Board, whose task is to advise the Federal Minister of Education, the Arts and Culture on a possible restitution.

Due to the extension of the period to be investigated, the provenance researchers of the Albertina will carry out investigations into the purchases from the German art trade between 1933 and 1938, into all purchases after 1960 and into acquisitions of the library, and a general object autopsy in order to look for indications of provenance on the originals as well as a systematic revision of the entire holdings of the works of Egon Schiele and Gustav Klimt.
