reservation land by lumber and land companies. The museum curates photographs documenting the work and gifts from Annishinabe people whose land was eventually returned. Between 1915 and 1929 A. V. Kidder excavated sites in the Pecos Valley, New Mexico and elsewhere in the American southwest. Kidder is known as the “father of archaeology” for his demonstration of the value of stratigraphic excavation in the Americas. With Carl Guthe and Anna O. Shepard, Kidder's analysis resulted in the first full chronology of southwestern archaeology. Inspired by questions raised at Pecos, Carl Guthe and Elsie Clews Parsons conducted ethnographic studies at Jemez and San Ildefonso Pueblos in the first use of analogy with the present as a tool in archaeological interpretation. The excavations at Pecos and related sites recovered more than 25,000 artifacts. Earnest Hooton at Harvard's Peabody Museum studied the more than 2,000 sets of human remains from Pecos in the first physical anthropological study of population groups through time. In 1927 Kidder held the first Pecos Conference, initiating regional archaeological conferences. The Pecos Conferences were first sponsored by the Peabody and later hosted by participating institutions. Third director, Douglas S. Byers, and curator Fred Johnson were national leaders in research and publication from 1938 through 1968. The Robert S. Peabody “Foundation for Archaeological Research” updated and revised cataloging, artifact storage systems, exhibits and publications. Fieldwork was focused on identifying the New England stratigraphic sequence. Johnson pioneered interdisciplinary paleoecological analysis for archaeological interpretation, applying it first to the Boylston Street Fish Weir in 1939. Excavation of Paleoindian occupations at the Bull Brook and Debert sites during the 1950s and 60s employed Pleistocene geology as an analytical tool. Extensive work was also undertaken in the Yukon and in Mexico. These excavations, plus several significant private collections, added another 200,000 objects. The RSPM hosted the initial meeting of the Society for American Archaeology in 1935 and inaugurated the Massachusetts Archaeological Society five years later. During the 1950s Fred Johnson chaired the American Anthropological Association committee linking the needs of archaeologists with the expertise of Willard F. Libby to develop Carbon 14 dating for archaeological sites. The Peabody hosted the 1954 Conference on Radiocarbon Dating and the 1956 International Conference on Radiocarbon Dating with representatives from seven European countries, Canada, and the United States. In 1968, Richard “Scotty” MacNeish was appointed Director. His major excavations in Mexico, Peru, and Belize investigated the origins of
