Ronald Godfrey Lienhardt (17 January 1921 – 9 November 1993) was a British anthropologist. He took many photographs of the Dinka people he studied. He wrote about their religion in Divinity and Experience: the Religion of the Dinka.
Born in Bradford, West Riding of Yorkshire, England, of mixed Swiss and Yorkshire parentage, he went to Cambridge University in 1939, where he read English at Downing College under F. R. Leavis until he was called up and became a transport officer, stationed in Africa. He was followed in 1946 to Downing by his brother Peter Lienhardt, who also read English and became an anthropologist. After returning to civilian life, Godfrey's academic interests were redirected to anthropology by an encounter with Edward Evans-Pritchard, under whom he subsequently studied at Oxford.
His chosen field of research were the Dinka of southern Sudan, a people closely related to the Nuer studied by his mentor, (1947–50) and the Anuak (1952-1954). His work on the former, culminating in Divinity and Experience: the Religion of the Dinka, is regarded as unsurpassed as a study of African religion. His central, ultimately Durkheimian premise here is that religion is not reducible to a matter of beliefs and practices, but rather to a complex set of natural and social practices. His methodology shows an acute sensitivity to the dangers of translating key words in an indigenous lexicon concerning belief and religion, for example, into Western languages.
