Sir Edmund Ronald Leach (7 November 1910 – 6 January 1989) was a British social anthropologist.
Edmund Ronald Leach was born on 7 November 1910 at Sidmouth. He attended Marlborough College, and won an Exhibition to Clare College, Cambridge, matriculating in 1929. He studied mathematics for the first year, then engineering, achieving a First in 1932.
After Cambridge, Leach worked initially as a commercial assistant for Butterfield and Swire in Shanghai, spending his holidays travelling around the country. He undertook anthropological field research in Botel Tobago, (Orchid Island, Taiwan) in 1938, before returning to England as a graduate student at the London School of Economics, where he studied under Malinowski. This was followed by further research in Kurdistan. From 1939-45 Leach was an army officer stationed in Burma, where he carried out more field work. He married Celia Joyce Buckmaster in 1940, and they had a daughter, Louisa.
After the war Leach returned to LSE to complete his PhD, and, after a brief spell in Borneo, became a lecturer, later a Reader, in Social Anthropology. In 1953 he moved to the Faculty of Archaeology and Anthropology at Cambridge University as a lecturer, then Reader, and was given his own chair in 1972. Leach's final piece of field work was undertaken in 1954-5 in Ceylon, where he studied the village of Pul Eliya.
Leach was made a Fellow of King's College in 1960 and was elected Provost in 1966. Alongside his work within Cambridge University, Leach was a Fellow of the Center for Advanced Study in Behavioural Sciences at Stanford University (1961); a member of the Social Science Research Council (1968); Vice President and then President of the Royal Anthropological Institute (1964-6, 1968-70), and an Honorary Fellow of the School of Oriental and African Studies. He won the Curl Essay Prize in 1951 and 1957 and the Rivers Medal in 1958, and delivered a controversial series of Reith Lectures in 1968.
Leach retired from the Provostship in 1978 and moved to Barrington. He died on 6 January 1989 .
