So called "degenerate art" (modern art "unworthy" in the eyes of the Nazis) was legally banned from entering Germany, and so once designated was held in what was called the Martyr's Room at the Jeu de Paume. Much of Paul Rosenberg's professional dealership and personal collection were subsequently so designated by the Nazis. Following Joseph Goebbels's earlier private decree to sell these degenerate works for foreign currency to fund the building of the Führermuseum and the wider war effort, Goering personally appointed a series of ERR-approved dealers including Hildebrand Gurlitt to liquidate these assets and then pass the funds to swell his personal art collection. With much of the looted degenerate art sold onwards via Switzerland, Rosenberg's collection was scattered across Europe. Unsold art (including works by Picasso and Dalí) was destroyed on a bonfire in the grounds of the Jeu de Paume on the night of 27 July 1942, an act of almost unparalleled vandalism. However, the Nazis had burned nearly 4000 works of German "degenerate" art in Berlin in 1939.
