Revisiting the numbers game

by Marc Masurovsky

Since 2011, the Holocaust Art Restitution Project (HARP) has periodically addressed the problematic of quantifying the thefts of art works, art objects, and other items of esthetic value, looted between 1933 and 1945 under National Socialist rule, during WWII and the Holocaust. After the conflict, there was no internationally-sanctioned and organized audit of cultural losses suffered by the victims of National Socialist and Fascist aggression on the European continent. Therefore, experts and amateurs alike have wallowed in the murky waters of estimations of human and material losses from 1945 to the present.

Regarding the scale of human losses, the international community accepts that between 45 and 55 million men, women, and children lost their lives as a direct and indirect result of the continental conflagration between September 1, 1939, and May 8, 1945. That figure includes the six million Jews targeted for physical extermination by the Nazi government. The continental theater of operations included 15 European countries (and North Africa) which were directly involved either as a result of being militarily occupied by Axis powers, annexed by Nazi Germany, or allied to the Axis: Norway, Denmark, Holland, Belgium, Italy, Germany, Austria, Poland, Czechoslovakia, Greece, Yugoslavia, Romania, Bulgaria, Hungary, the Soviet Union, North Africa (Morocco, Algeria and Tunisia).

Wherever the German Army and the Nazi political and security apparatus went, there followed intense repression, the physical eradication of local populations accompanied by systematic, State-sponsored acts of plunder and illicit displacement of individual and communal properties.

By the time Nazi Germany agreed to terms of unconditional surrender on 8 May 1945, the Allies had realized that “art treasures” (museum-quality objects) were systematically looted across Axis-controlled Europe, stored away in gigantic depots or sold on the international art market to replenish the Reich’s warmongering coffers. Allied focus on “art plunder” went hand in hand with “rescuing the treasures of Europe” and returning them to the countries from which they had been forcibly removed. In and of itself, this task was barely manageable, but if you factored in “everything else” that was stolen, the task was simply unmanageable and would have required several decades of full-time focus by myriad specialists from the victorious nations to sort out what had been stolen by 1945, what was recovered, and what was still missing as of Victory-Day (V-E-Day).

The ex-Soviets always wanted to do things their own way, which, if you look back at the consequences of WWII on the Soviet Union’s infrastructure, human and industrial capital and cultural infrastructure, you might understand some of their reasoning. Their losses for the period of 1941-1945 are estimated in the millions. One snapshot of these staggering figures can be best summed up by their estimation of museum losses: 1,129,929 units of conservation comprising objects, rare books, manuscripts, as well as archival collections.https://lostart.ru/fr/svodnyj_katalog/

Some more elliptical estimates suggest that 20% of European art was plundered “from Jewish collectors and other individuals and organizations.” We don’t know what 100% amounts to, which would represent the universe of “stealable” European art. Hence, the 20% ratio seems a bit vapid and lacking substance. 

We still don’t really know…

In the media-hungry and attention-starved world that we all bask in, there has developed an insatiable appetite to provide numbers that explain the true extent of the plunder and what is still missing. These valiant self-interested pronouncements do not usually come from historians and experts who, for professional reasons, are reluctant to venture in such murky and troubled waters. They emanate from politicians, international personalities, media hounds, and anyone seeking attention for not more than 3 minutes but whose pronouncements will live on forever as random digital factoids on the Internet which end up restated and reposted blindly and thoughtlessly. Repeated enough times, they are true. Fact-checking, go take a hike!

So, what’s the problem exactly?

In November-December 1998, an international conference dubbed the Washington Conference on Holocaust-era Assets took place in Washington, DC. It brought together under one roof 44 nations and a smattering of NGOs to assess where we were with respect to honoring postwar claims for compensation and restitution submitted by Holocaust victims’ families to the governments of their adopted countries and against the main architects and perpetrators of the horrors unleashed upon them and their families—Germany and its allies. Although the results of the Washington Conference were mixed, a set of eleven principles was released on its last day to guide the art market and governments on how to address the possibility that looted art objects may have entered public collections and businesses and how to resolve these claims to everyone’s satisfaction (one would only hope…). These principles avoided mentioning anything about the private art market and—in true diplomatic verbiage—kept the notion of plunder at its vaguest and limited the main perpetrators to “the Nazis.”

Ronald Lauder, who, at the time of the December 1998 Washington Conference, was Chairman of the Board of the Museum of Modern Art (MoMA) in New York and the chairman of the recently-established Commission for Art Recovery (CAR), proclaimed that 110,000 art works were still missing, half of the total number that was allegedly stolen (or 220,000)-- a figure advanced without a hint of critical insight as to its veracity and on what facts it rested. He also placed a value on the missing works: 10-30 billion dollars (1998 value). This would assign an approximate value per object of 100,000 dollars, give or take 50,000. The average value of art objects looted from Jewish owners could be estimated grossly at between 5 and 10,000 dollars (1998) and that is still an uneducated guess. Only 5 to 15%--again, uninformed guesses based on years spent reviewing restitution claims and Nazi inventories of stolen property—reached or exceeded the values hypothetized by Mr. Lauder.

Mr. Lauder's estimates pale against those proffered by the Polish government. They estimate that their battered nation alone lost 600,000 works of art, many of which remain unrecovered. 

Since 1998, the London-based Art Loss Register (ALR), one of the most important proprietary (privately-owned) databases of stolen art in existence today, proffered an estimate of 200,000 stolen works of art, and even averred that 170,000 had been recovered and therefore that would leave only 30,000 still gallavanting about and waiting to be plucked for a handsome finder’s fee. These figures are astounding for several reasons: 1/ they are unjustified and unverifiable; and 2/ they presume a rate of restitution of more than 85%! A rather extraordinary feat which, it too, is surreally wrong. Of course I invite you all to fact-check this and contact ALR directly to verify or infirm the above.

600,000 art objects stolen, 100,000 still missing

This formula, backed up by no scientific research or historical documentation, has been the most popular mantra proffered by government officials, reporters, and restitution lawyers.

The most notable proponent of this statistic is Ambassador Stuart Eizenstat, currently Special Advisor on Holocaust Affairs to the US Secretary of State and an internationally-recognized authority on the diplomacy of reparations for Holocaust victims. He first posited (as far as we can tell) these figures at an international conference held in Prague (Czechia) in June 2009. Mr. Eizenstat repeated those figures as recently as 2018 which were reported in 2019 by the Washington Post.

These figures have also been repeated in the following media outlets:

-history.co.uk,
-Time Magazine,
-the Smithsonian Magazine in 2022,
-Swissinfo.ch
-Deutsche Welle
The DW article contradicts itself when, in the same breath, it posits that 5 million artworks changed hands illegally. Which is it?
-The LA Times, whose editorial board actually wondered whether the estimates might be much higher.
-National Public Radio
-and, of course, the US Department of State

Other far-flung estimates include:

-30,000 looted art works are still missing
-10,000 works are still missing

How do we stop the misrepresentation of one of the most heinous crimes committed against culture, against humanity as part of a genocide of the Jewish people?

When someone asks you how many objects were looted during the Nazi years (1933-1945), 

1/ you do not to provide an accurate figure because there is none. 

2/ You do not know how many objects have been recovered, 

3/ you do not how many have been restituted, and how many are still missing, regardless of style, value, and importance to art world denizens. 

4/ you must err on the side of caution and state in all seriousness: between six and ten million.

Restitution and ‘restitution’: Some thoughts on the MNR problem in France

by Marc Masurovsky
edited and updated on 5 July 2025

Restitution involves the act of returning a stolen object to the owner who was the victim of the theft.

However, if a gallery sells a painting to a citizen of the German Reich who then takes it home across the Rhine, does that constitute theft, especially if the object itself is proven not to have been stolen in the first place?

When the French claims agency, the Office des Biens et Intérêts Privés (OBIP) transferred a painting to the Selection Committee (Commission de choix) of the Louvre in December 1951, it implied that the Selection Committee and/or the Louvre had lost the painting in the first place and justice was being served by incorporating the painting into French State collections. In this particular instance, the painting, Vénus, Bacchus, Cérès, amours et saphirs, by Frans Floris, had been sold in 1941 to a leading German agent—Karl Haberstock--through a gallery owned by Hugo Engel in German-occupied France. Although the item had not been stolen prior to sale, the postwar French government nevertheless treated the work as a stolen object. One year after the liberation of North Africa by Anglo-American troops and contingents of the French Resistance in November 1942, the French National Liberation Committee had declared that all transactions on French territory since June 1940 were deemed null and void, an act which paved the way for a complex and lopsided campaign of restitution and compensation in the years following the Liberation of France in the second half of 1944. For all intents and purposes, the act of declaring a transaction null and void conferred on the transacted object the taint of illegality.

Let’s pretend for a second that France had not been invaded by Nazi Germany. Hugo Engel still would have offered the Fioris painting to Karl Haberstock, a Nazi cultural agent, who then returned to the Reich with it, acting on behalf of his superiors in the Nazi hierarchy. The French government would not have objected to the sale and departure of this object from French territory. But all of that changed with the German invasion of France and the subsequent wholesale requisitions, acts of plunder and spoliation that befell those living within its now truncated borders. The Floris painting was no longer just another painting being offered for sale in a Paris gallery. It was now treated as if it belonged to France, in other words, its acquisition and transfer to Reich territory was tantamount to a forcible removal of the painting from the bosom of that organic national entity known as France. In sum, a war of aggression and conquest against France waged by Nazi Germany had transformed the privately-owned Fioris painting into a State-controlled object that earned it the full protection and consideration of the French State. A curious turn of alchemy which afforded France to lay claims in the postwar to a significant haul of art that had emanated from its private art market and been acquired by individuals who had transported their cultural purchases outside its borders into the Reich.

The Allies countenanced this conversion of private commercial transactions under Nazi rule into illicit acts of property transfers, thus equating them with actual acts of plunder and misappropriation. Regardless of how one judges this policy, it has produced, among other things, an awkward category of objects known as the MNRs—Musées Nationaux Récupération. Many of the MNRs fall into the category of the Fioris painting—acquired in the open private art market during the German occupation and removed from French territory by the purchaser. There is no evidence that the Floris painting was, in fact, incorporated into the MNR category since it is absent from the French government's website devoted to those objects.

The question now becomes: should the MNR’s even exist since they are as close to war booty as one can get, save for those which are, beyond a shadow of a doubt, plundered objects? The maintenance of this ambiguity forces us to consider that all objects acquired in France—fair and square—during the period of Vichy rule and German occupation—from June 1940 to the fall of 1944—should be considered as illicit transfers of property until otherwise stated. One can’t have one’s cake and eat it too, but it appears that, for the past eighty years, that is precisely what has occurred, thus casting an inexorable taint of wartime theft and illegality on an unimaginable number of cultural objects that have since made it into countless collections on both sides of the Atlantic Ocean.

Update on 5 July 2025

Since this article was written in 2011, the French government has changed its tune regarding the so-called MNR works and objects of which they are the custodians until the rightful owner(s) state their claims for their restitution, historical evidence in hand. Close to 50 objects have been returned since 2011, a small number but a significant leap forward when compared to the prior 60 years since the MNRs became a "thing."

The French government is still unwilling to admit that most of the works that fall under that label are not Jewish losses. They are simply works and objects that changed hands under the pseudo-legality established by the Vichy regime under German military occupation. Neighboring countries under the Nazi yoke also saw their art markets fructify and grow as if nothing untoward had happened. Another way of saying that the art market is impervious to the vagaries of history. As long as someone has something to sell, there will be a buyer willing to plunk down the requisite sum of money to acquire it in good faith.

Looking back, I speculate that the decision by the French Resistance to declare all transactions null and void may have been a principled, although ill-thought out declaration not realizing how potentially sweeping and destructive its literal enforcement would have been in the postwar years. It foreshadows to some extent Law 59 which was passed in the US Zone of Occupation in Germany in order to hold accountable current possessors of objects acquired during the Third Reich. There is nothing wrong with making the last owner/possessor accountable as an enforcement to establish the circumstances of an acquisition during the commission of an act of genocide.
