Pinakothek Munich: artworks with no provenance transferred from the German state

Where to find the provenance of artworks held at the Pinakothek in Bavaria, Germany?

Not, it seems, on the Pinakothek website.

Frequently, the information provided in the Origin or Herkunft field limits itself to the mention: "on loan" or "transferred from the German state".

But there is no link or reference to any further information. 

Yet we know that many looted artworks returned to Germany after the war and then distributed to museums "on loan" or as "transfers").

How to verify whether or not an artwork held at the Pinakothek is referenced in the database, the DHM Munich or Linz databases?

To find out, we will look at a selection of artworks at the Pinakothek, many of which are "on loan" or transferred from State possession.

Waldmüller, Hitler and Collections Today

Hilter loved the art of Ferdinand Georg Waldmüller (15 January 1793 in Vienna – 23 August 1865 in HinterbrühlAustria). Waldmüller was a Nazi favourite. So much so that in examining the provenances 
of Waldmüller art acquired after 1933, one can reasonably wonder : 

How likely is it that this Waldmüller did not pass through Nazi hands?

In this post we try to get a sense of what is known (and not known) about the provenance of artworks attributed to Waldmüller.

Looted Art Detector Tool: Swiss GLAMHACK2021

Objective: Identify high priority artworks for provenance research

Description: Online Free Digital Tool

Approach: Automatic text analysis using frequency counts

note: The frequency counts target textual indicators of UNCERTAINTY, UNRELIABILITY,  or ANONYMITY, as well as the possible presence of RED FLAG names related to NAZI-looted art, forced sales and duress sales. 
The resulting calculations do not signify that an artwork is looted. They simply quantify observations concerning the text for further analysis.

How it works:

Cultural property at the Oberfinanzdirektion München Bundesarchiv: archives



In attempting to verify one of the names that appears in a provenance with an extremely high Uncertainty Index (Bottenwieser), we stumbled upon an archive file (xml) in German that contains the names of many plundered Jewish collectors (and other people as well).  

Are there names here that should be plugged into the Looted Art Detector? 

Below is a Google translation of the first few paragraphs of the German text followed by the text itself.

Let's run 1000 NEPIP provenances that contain Munich through the Looted Art Detector

In the previous post we gathered one thousand provenances of artworks listed (for the most part) by American museums on the Nazi Era Provenance Internet Portal that contain the word "Munich" or "München" in the provenance text.

In this post, using the Looted Art Detector developed at the Swiss Glamhack2020 and Glamhack2021, we rank artworks that contain a mention of Munich according to the criteria of "Uncertainty".

Data Visualization Test

How to grasp the scale of the transfer from Jewish art collectors persecuted by the Nazi to museums in the United States, Germany, Austria, France, Switzerland, the Netherlands, as well as countries in South America?

Some experiments in data visualization.

First, an overview (attention: the figures are not real, they are only to test the visualization.)

The Nazis looted so much. Destroyed so many lives. How to represent this in a way that is understandable, meaningful - and actionable?

The devil is in the detail.
