 In July 1940, Nazi Alfred Rosenberg established the Parisian base of the Einsatzstab Reichsleiter Rosenberg (ERR), whose purpose was to confiscate masonic artifacts and the highest-quality works of art for Hitler's planned Führermuseum in Linz, Austria.All looted art works, including Paul Rosenberg's, were initially shipped by truck to the depot created in the Galerie nationale du Jeu de Paume.There Nazi art historians, experts, photographers, and maintenance and administrative personnel appraised, filed, photographed and packed what were now termed "ownerless cultural goods" for rail transport to Germany.
