(now the Museum of Cultural History). It was based in Victorian folklore and museum approaches. By founding the department at Bergen, Barth hoped to create a modern, world-class department with an approach similar to those found in England and the United States. Barth remained at Bergen from 1961 to 1972. During this time his own work developed in two key ways. First, he developed research projects inside Norway (and published a study entitled The Role of the Entrepreneur in Social Change in Northern Norway in 1963). Second, he began writing more purely theoretical works that secured his international reputation within anthropology. These included Models of Social Organization (1966) and especially the small, edited volume, Ethnic Groups and Boundaries: The Social Organization of Cultural Difference (1969). Barth's introduction to Ethnic Groups and Boundaries became his most well-known essay and "ended up among the top 100 on the social science citation index for a number of years.". In 1974 Barth moved to Oslo, where he became professor of social anthropology and the head of the city's Museum of Cultural History. During this period, anthropology was changing. Marxism and interpretive approaches were becoming more central, while Barth's focus on strategy and choice was being taken up by economics and related disciplines. Barth shifted to studying meaning and ritual as developed in ethnic groups, and conducted research in Papua New Guinea, where he conducted fieldwork with the Baktaman. He published several works from these studies, namely the Ritual and Knowledge among the Baktaman of New Guinea (1975). He also continued studies in the Middle East, conducting fieldwork in Oman with his wife Unni Wikan. This resulted in his 1983 volume Sohar: Culture and Society in an Omani Town. Barth received a state scholarship from the Norwegian government in 1985. He left the country to accept two positions in the United States—at Emory University from 1989 to 1996, and Boston University from 1997 to 2008. By this time, Barth and his wife "felt we had both done our share of physically strenuous fieldwork" and decided to begin an ethnographic project in Bali. He developed an interest in the anthropology of knowledge at around this time, an interest which he explored in his book Balinese Worlds (1993). More recently, he has also conducted research in Bhutan. Barth was a member of the Norwegian Academy of Science and Letters. In 1997 he was elected a Foreign Honorary
