Cross Hall. Central air conditioning was added, as well as two additional sub-basements providing space for workrooms, storage, and a bomb shelter. The Trumans moved back into the White House on March 27, 1952. While the Truman reconstruction preserved the house's structure, much of the new interior finishes were generic and of little historic significance. Much of the original plasterwork, some dating back to the 1814–1816 rebuilding, was too damaged to reinstall, as was the original robust Beaux Arts paneling in the East Room. President Truman had the original timber frame sawed into paneling; the walls of the Vermeil Room, Library, China Room, and Map Room on the ground floor of the main residence were paneled in wood from the timbers. Jacqueline Kennedy restoration Jacqueline Kennedy, wife of President John F. Kennedy (1961–63), directed a very extensive and historic redecoration of the house. She enlisted the help of Henry Francis du Pont of the Winterthur Museum to assist in collecting artifacts for the mansion, many of which had once been housed there. Other antiques, fine paintings, and improvements from the Kennedy period were donated to the White House by wealthy philanthropists, including the Crowninshield family, Jane Engelhard, Jayne Wrightsman, and the Oppenheimer family. Stéphane Boudin of the House of Jansen, a Paris interior-design firm that had been recognized worldwide, was employed by Jacqueline Kennedy to assist with the decoration. Different periods of the early republic and world history were selected as a theme for each room: the Federal style for the Green Room, French Empire for the Blue Room, American Empire for the Red Room, Louis XVI for the Yellow Oval Room, and Victorian for the president's study, renamed the Treaty Room. Antique furniture was acquired, and decorative fabric and trim based on period documents was produced and installed. The Kennedy restoration resulted in a more authentic White House of grander stature, which recalled the French taste of Madison and Monroe. In the Diplomatic Reception Room, Mrs. Kennedy installed an antique "Vue de l'Amérique Nord" wallpaper which Zuber & Cie had designed in 1834. The wallpaper had hung previously on the walls of another mansion until 1961 when that house was demolished for a grocery store. Just before the demolition, the wallpaper was salvaged and sold to the White House. The first White House guidebook was produced under the direction of curator Lorraine Waxman Pearce with direct supervision from Mrs.
