Octagon (Washington, D.C.), 1922-1930, 1945-1950, undated

These records document Kimball's involvement as first Chair (1945-1947), and later Member (1948-1950), of the American Institute of Architect's Committee on Restoration of the Octagon. The Octagon (1799-1801) was designed by William Thorton as a residence for Col. John Tayloe III and in 1899, became the Institute's headquarters. Kimball's committee was charged with restoring the building as a historic monument, refurnishing its interior appropriately, and raising the necessary funds. The records are comprised primarily of correspondence, much of it with architect and author Thomas Waterman who served as restoration consultant, other members of the Committee, and directors of the Institute. Also includes some ephemera, photographs, and notes, as well as a small amount of material documenting Kimball's earlier role as a member of the Building Committee which oversaw the development of the Octagon and related property in the 1920s.
