Another closet extended from the west into the northwest corner of the room. To accommodate these spaces, the northern wall of the large bedroom was made convex. It continued to be used as a sitting room by Bess Truman, but reverted to bedroom space in 1953. It has remained in its 1952 configuration ever since, and has been occupied by First Lady Mamie Eisenhower; First Lady Jacqueline Kennedy; First Lady Lady Bird Johnson; First Lady Pat Nixon; President Gerald R. Ford and his wife, Betty; President Jimmy Carter and his wife, Rosalynn; President Ronald Reagan and his wife, Nancy; President George H. W. Bush and his wife, Barbara; President Bill Clinton and his wife, Hillary; and President Barack Obama and his wife, Michelle. The Presidential Bedroom Suite dressing room was part of the Executive Residence when it was completed in 1809. A full bath was added to it some time before 1849. The bath was expanded to take up half the dressing room's space in the 1952 reconstruction. The dressing room has not always served as a dressing room, however. It served as a small bedroom for Susanna Adams, daughter of President John Adams; Louisa Smith, niece of First Lady Abigail Adams; Tad Lincoln, son of President Abraham Lincoln; Robert Johnson, son of President Andrew Johnson; Anne Thompson, nursemaid to the young children of President Grover Cleveland; First Lady Eleanor Roosevelt; and First Lady Bess Truman. It was used as a private study of by First Ladies Lucy Webb Hayes and Lou Henry Hoover, and as a private dining room by President Woodrow Wilson and his second wife, Edith. First Lady Florence Harding used it as a dress storage room. It also served as a combination dressing room/sitting room/office to First Ladies Mamie Eisenhower, Jacqueline Kennedy, Lady Bird Johnson, Pat Nixon, Betty Ford, Rosalynn Carter, Nancy Reagan, Barbara Bush, and Hillary Rodham Clinton. Michelle Obama used it as a dressing room. West Sitting Hall did not exist when the White House was completed in 1809. James Hoban's original design for the White House had a flight of stairs, one against the north wall and one against the south wall, on the Ground Floor. These rose to a landing, and then a single flight of stairs rose to the Second Floor. This left only a small area north and south of the staircase, which by 1865 was being called the West Hall. In 1869, President Grant rebuilt the stairs so that the single staircase rose against the south wall.
