the groundwork for the creation of a research institute. They greatly increased their already considerable collection of artworks and reference books, forming the nucleus of what would become the Research Library and Collection. In 1938 they engaged the architect Thomas T. Waterman (1900–1951) to build two pavilions to house their Byzantine Collection and an 8,000-volume library, and in 1940 gave Dumbarton Oaks (which included about of land) to Harvard University, Robert Bliss's alma mater. At the same time they gave a portion of the grounds—some 27 acres—to the National Park Service to establish the Dumbarton Oaks Park. In 1941, the administrative structure of Dumbarton Oaks, now owned by Harvard University, was modeled according to the following design: the Trustees for Harvard University, composed primarily of the President and Fellows of Harvard College, made all appointments, including those to the Administrative Committee, which in turn would supervise the entire operation and refer to the Trustees such recommendations as may require their action. This committee was first chaired by Paul J. Sachs (1878–1965), Harvard Professor and Associate Director of the Fogg Art Museum, but by 1953 it was chaired by the Dean or Provost and, beginning in 1961 and thereafter, by the President of Harvard University. In early years the Administrative Committee appointed a Board of Scholars to make recommendations in regard to all scholarly activities. The Board of Scholars was first organized in 1942 (with eleven members, of which seven were from Harvard); its membership was increased to twenty-two members by 1960. In 1952, this board was titled the Board for Scholars in Byzantine Studies. In 1953, a Garden Advisory Committee was created to make recommendations in regard to the garden and, later, to the Garden Library and its Fellows, and in 1963 an Advisory Committee for Pre-Columbian Art was created. The Administrative Committee also historically appointed a Visiting Committee consisting of persons interested in the welfare and broad aims of Dumbarton Oaks. This committee was abolished in 1960 when it was replaced by a Board of Advisors. Wishing to increase the scholarly mission of Dumbarton Oaks, in the early 1960s the Blisses sponsored the construction of two new wings, one designed by Philip Johnson (1906–2005) to house the Robert Woods Bliss Collection of Pre-Columbian Art and its research library and, the other, a garden library designed by Frederic Rhinelander King (1887–1972), of the New York City architectural firm Wyeth and
