I’m talking about decor, and her enormous efforts to acquire donations of important antique furnishings, paintings, etc.
You’re right. Jackie Kennedy worked to make the White House rooms as historically accurate as possible. She worked to get as many of the original furniture pieces back to the White House. She managed to get quite a few items from private owners, and pursued private money donations to purchase period pieces. Say what you will about Jackie Kennedy, but she did know fashion, and she was untiring in trying to bring the history of the White House back to life. If I’m not mistaken, she had a leading role in preserving New York’s Grand Central Station, and I am under the impression that she was a behind-the-scenes supporter for the preservation of Willard’s Hotel, among other Washington buildings.
