Tracing the Nazi extermination of Jewish art collectors with Wikidata Sparql Queries


How to represent the impact of the Holocaust?

Inhumanly huge numbers defy our capacity to understand.

How to depict both the fates of individuals and the larger context, without losing sight of either?

In this next series of posts we attempt to find a way to show what happened to Jewish art collectors and their world during and after the Holocaust.


Timeline from Wikidata Query

As Jewish art collectors, dealers, artists, curators, historians  and museum personnel were being targeted for persecution, robbery and murder by Germany's Nazi government, covetous eyes fixed upon their precious art collections. 


How can we document and visualise this massive double movement: the persecuted people on one hand and their possessions on the other?

We will begin with the people. Those who did not manage to flee, and who ended up murdered in Nazi camps or ghettos.




Each and every one of these individuals had a story: a family, friends, business and social relations, activities, passions, beliefs, enthusiasms, achievements, foibles; a life filled with events and people and - in the case of the individuals whose stories we trace here -  art.



How can we gather the huge amount of information and comprehend how it all fits together and what it means? 

This is not a small challenge.
___


One of the best tools for dealing with large amounts of linked information, such as relationships between people, places, things and events, is Wikidata.







Why Wikidata?


1) STRUCTURED

Because Wikidata is open yet structurally rigorous where it matters.
Wikidata has built into it a linked data structure that can be read by both humans and machines. 

2) OPEN TO THE OUTSIDE WORLD
Wikidata can be used for querying not only what is referenced in Wikidata itself, but also for linking to information that is held outside of Wikidata which shares a reference or authority file.

3) DATA QUALITY

For the art world and the Holocaust, Wikidata has remarkably rich data. Though still a work in progress with much that remains to be done, Wikidata is already far more reliable and complete in the topics that concern us than any other database, authority file or linked dataset that I know of.

4) CROWDSOURCED

The task of telling the story of the Jewish art world and what happened to the people and the artworks during and after the Holocaust is too big for any one person or institution. There are so many people and events and places and objects, so many photos and documents, so many sources, so many languages. It is a job for every individual of good faith who wants to contribute to the sum of our knowledge.

5) WIKIMEDIA FOUNDATION

Because Wikidata is driven and maintained and enriched by very clever and hardworking people, and whatever innovations and advances are achieved become available to all of us, for free, where amazingly powerful tools cost only the effort of learning how to use them.


In this next series of posts, I hope to share some ideas and practical tips for using Wikidata Sparql queries to better understand the fates of Jewish art collectors and their collections, both collectively and individually. 


I hope that Holocaust scholars, art historians, provenance researchers, families and their advocates will find some of this useful, and that Sparql mavens will engage with the queries to improve them for the benefit of all.





(My apologies in advance to people who actually know how to write Sparql queries, and my thanks in advance for improving upon these amateurish efforts.)

The Holocaust and the art market: What does it mean to find Kieslinger in a provenance?



What does it mean to find the name Franz Kieslinger in a provenance? 
(above "Acquired from Dr. Franz Kieslinger, expert at the Dorotheum, Vienna, for 40 Reichsmarks in 1939"

Franz Kieslinger was, first and foremost, a Nazi art looter.
His name in a provenance is a screaming Red Flag. 
This does not mean, of course, that every artwork he touched was looted from Jewish collectors, but his name indicates a high probability of a serious problem.  



In which art collections does his name appear today, in 2020?


1. Albertina Museum, Vienna, Austria.


The National Fund of the Republic of Austria for Victims of National Socialism lists six artworks at the Albertina Museum that passed through the hands of Nazi art looter Franz Kieslinger, all of which were acquired in 1939.


Gentleman in blue high-necked coat with golden cordingAnonymous, attributed to 'German artist'28378Acquired from Dr. Franz Kieslinger, expert at the Dorotheum, Vienna, together with inventory numbers 28377, 28379, 28380 for 360 Reichsmarks in 1939

Officer in blue uniform with red collar and cannon crossAttributed to Grahl, August (1791 - 1868)28379Acquired from Dr. Franz Kieslinger, expert at the Dorotheum, Vienna, together with inventory numbers 8377, 28378, 28380 for 360 Reichsmarks in 1939
Triumphal gate in InnsbruckHagenauer, Karl (1898 - 1956)28207Acquired from Franz Kieslinger, expert at the Dorotheum, Vienna, for 30 Reichsmarks in 1939
Underdrawing for 'Aus dem Leben eines Wüstlings' (From the Life of a Libertine)Genelli, Bonaventura (1798 - 1868)28323Acquired from Dr. Franz Kieslinger, expert at the Dorotheum, Vienna, for 40 Reichsmarks in 1939



see: https://www.kunstdatenbank.at/search-for-objects/fulltext/kieslinger


Comments: First of all, it should be noted that the provenance for the Genelli featured above is pubished NOT on the Albertina Museum website but rather on the separate website of the National Fund of the Republic of Austria for Victims of National Socialism. 

Below is a screenshot from 23 April 2020 of the artwork as it appears on the Albertina Museum website. There is no provenance listed at all. This means that any search - even an Advanced Search - on the Albertina website will not pick up the artwork if one searches "Provenienz" for Kieslinger.






Secondly one notes that none of the artworks listed as having Kieslinger in the provenance are from what the Nazis labeled "degenerate" artists like Schiele. This is rather surprising as Kieslinger was known to have been involved in the expropriation of at least one Jewish collector of these artworks. 

This suggests that the listings, not only of the Albertina Museum but also possibly of even the National Fund of the Republic of Austria for Victims of National Socialism might be incomplete.

Who can verify this and if necessary add the information?

Art Market and the Holocaust: New Questions about the Miedl Looted Art Network



Art Market and the Holocaust: New Questions about the Miedl Looted Art Network





Alois Miedl: art looter 

Miedl's network according to the Art Looting Investigation Unit Final Report of 1946 Red Flag Names List includes a number of names that appear frequently in provenances. Every one of the names below was identified as a Red Flag Name by the ALIU.

Questions for Holocaust-era art historians: Which artworks in which collections include any of these names in their provenance?

Are there gaps in the ownership history 1933-1945?

What is the appropriate action to resolve these unclear provenances?
