French senator Corinne Bouchoux is urging French museum officials to take closer looks at their prized holdings as many public art collections contain works looted by Nazis during World War II. Bouchoux has led an investigative committee devoted to uncovering Nazi-looted artwork in France, which prompted her to ask museums to be more thorough in their provenance research.

Bouchoux revealed that out of the 100,000 artworks stolen from Jewish families in France and Belgium, approximately 2,000 of those works were still present in French museums. Many of these museums were designated “national museums of recovery,” which allowed the institutions to keep the works as long as they did not become property of the state and if identified, the rightful owners could reclaim them.

Bouchoux wrote her doctoral thesis, which has just been published as a book, on Nazi-looted art in France and has suggested nine proposals to direct the stolen works back to their rightful owners or offer restitution for them.

In line with Bouchoux’s efforts, the Shoal Memorial in Paris presents the exhibition Looting of the Jews: A State Policy (1940-44), which grants visitors a glimpse of the goods, including artworks, that originally belonged to Jews in France. The show is on view through September 29, 2013.
