Robert Stewart Culin was an American ethnographer and author interested in games, art and dress. Culin played a major role in the development of ethnography, first concentrating his efforts on studying the Asian-Americans workers in Philadelphia. His first published works were "The Practice of Medicine by the Chinese in America" and "China in America: A study in the social life of the Chinese in the eastern cities of the United States", both dated 1887. He believed that similarity in gaming demonstrated similarity and contact among cultures across the world.

Frank Hamilton Cushing was an American anthropologist and ethnologist. He made pioneering studies of the Zuni Indians of New Mexico by entering into their culture; his work helped establish participant observation as a common anthropological research strategy. In recent years, however, questions have emerged about Cushing's activities among the Zuni. Consequently, Frank Cushing's work provides an important case study for considering the ethics of both ethnographic research and the generation of museum collections.
