Reo Franklin Fortune (27 March 1903 – 25 November 1979) was a New Zealand-born social anthropologist. Originally trained as a psychologist, Fortune was a student of some of the major theorists of British and American social anthropology including Alfred Cort Haddon, Bronislaw Malinowski and Alfred Radcliffe-Brown.[1] He lived an international life, holding various academic and government positions: in China, at Lingnan University from 1937 to 1939; in Toledo, Ohio, USA from 1940 to 1941; at the University of Toronto, from 1941 to 1943; in Burma, as government anthropologist, from 1946 to 1947;[1] and finally, at Cambridge University in the United Kingdom from 1947 to 1971, as lecturer in social anthropology specialising in Melanesian language and culture.[2]
He was first married to Margaret Mead in 1928, with whom he undertook field studies in New Guinea from 1931 to 1933.[3] They divorced in 1936. Fortune subsequently married Eileen Pope, also a New Zealander, in 1937.[4]
Fortune provided significant insights into the consequences of matrilateral and patrilateral cross-cousin marriage in advance of work by Claude Levi-Strauss. He is also known for his contribution to mathematics with his study of Fortunate numbers in number theory.[5]
The 2014 novel Euphoria by Lily King is a fictionalized account of the relationships between Fortune, Mead and Gregory Bateson in pre-WWII New Guinea.[6]
