The renowned anthropologist Margaret Mead (1901-1978) worked in the Museum's Anthropology Department from 1926 until her death. Through her groundbreaking expeditions to Samoa, New Guinea, and Bali, Mead brought anthropological work into the public consciousness. Her studies provide the foundation for the Hall of Pacific Peoples, which reflects a remarkable geographic and cultural diversity. The Hall explores the cultures of the South Pacific islands, which range from tiny stretches of land to the island continent of Australia and include Polynesia, Micronesia, and Melanesia. Highlights include a display of elaborately painted and adorned dance masks from Northern New Ireland, part of Papua New Guinea. Made of wood and bark fibers, the masks represent specific spirits and are used in traditional dance ceremonies. Also on view are intricately detailed shadow puppets from Java. Originating in the 11th century, Javanese puppet theater is used as an educational tool to communicate information about religious tenets, moral codes, history, and myths.
