The Orangerie was joined with the Louvre in 1930. The western half of the Orangerie was dedicated to temporary exhibitions for the Louvre and other national museums in France. Each year, the Orangerie hosted a variety of exhibitions. From 1930 to 1933, the Orangerie hosted an exhibition on
Impressionism. In 1934, the exhibition
Peintres de la realité (Painters of Reality) was dedicated to the 17th century and became famous. In 1936, the exhibition
Rubens et son temps (Rubens and his Age) attracted a million visitors to the museum. There was an entire exhibition dedicated to
Degas in 1937, titled in his name. In 1942, there was an exhibition dedicated entirely to
Arno Breker, who was an official artist of the
Third Reich and who studied in
France. In 1946, after the end of
World War II, many masterpieces from private collections were recovered in
Germany by the French Commission for Art Recovery and the
Monuments Men and they were displayed in the Orangerie. ==The Jean Walter and Paul Guillaume Collection==
