Elizabeth Florence Colson (June 15, 1917 – August 3, 2016) was an American social anthropologist and professor emerita of anthropology at the University of California, Berkeley. She was best known for the classic long-term study of the Tonga people of the Gwembe Valley in Zambia and Zimbabwe, which she began in 1956 with Thayer Scudder, 11 years after she obtained her doctorate and while Scudder was a second-year graduate student. Dr. Colson focused her research on the consequences of forced resettlement on culture and social organization, the effects of economic pressure on familial relationships, rituals, religious life, and even drinking patterns.
