Raubkunst
Jeu de Paume was used from 1940 to 1944 to store Nazi plunder looted by the regime's Reichsleiter Rosenberg Taskforce (ERR) in France (see Rose Valland). These works included masterpieces from the collections of French Jewish families like the Rothschilds, the David-Weills, the Bernheims, and noted dealers including Paul Rosenberg who specialised in impressionist and post-impressionist works.
