Who owned Pissarros? What else did they own? Where are they today?


What else?  German and French Jews who were persecuted by the Nazis often owned artworks from several different artists. If one focuses on claims for one artist, can one then expand the search to see what other artworks were stolen?

In this post we look at artworks by Pissarro which are being searched for by the families of Jewish art collectors who were plundered and persecuted during the Nazi era. And then we ask: what other artworks were owned by (and possibly stolen from) these same collectors?

To gather these artworks, and the information about them, we will use Wikidata queries. The graph structure enables us to start from one point (the collector) and move to other artworks owned all around the world. (if the ownership information has been entered in Wikidata.

Databases consulted: Lostart.de and ErrProject

Remarks: There are 48 German and French art collectors who owed Pissarros in these Nazi-looted art databases. Hugo Simon and Jules Lindauer appear in both LostArt and ERRPROJECT but otherwise there is little overlap.  To have a more complete view of Pissarros looted from (or acquired under duress from) Jewish collectors, one would need to consult databases in The Netherlands, Austria, Belgium, Poland, and elsewhere. In short, this is a glimpse or a sampling, not a complete overview.  


The appearance of any of the above names in a provenance for any artwork is an obvious red flag.


Are there any patterns we might be able to detect using the Wikidata general knowledge graph?
