Terence Turner , Emeritus Professor of Anthropology at the University of Chicago and Cornell University, has worked with the Kayapo of Central Brazil since 1962. His writings on the Kayapo cover social organization, myth, ritual, history, politics, values, and inter-ethnic relations. He has also published numerous papers on general theoretical topics, including structural analysis and interpretation of ritual and myth, the social construction of the body, emotions and subjectivity, family structures and kinship terminology, the application of aspects of Marxian theory to anthropology, and the theoretical basis of anthropological approaches to human rights, multiculturalism, and activism in support of indigenous causes. He has made a number of ethnographic films about the Kayapo with the British Broadcasting Company and Granada Television International. In 1990 he founded the Kayapo Video Project, through which the Kayapo have become able to shoot and edit videos about their own culture and encounters with Brazilian society.
