Evans-Pritchard (1902-1973) was an English anthropologist who was instrumental in the development of social anthropology. His first fieldwork began in 1926 with the Azande, a people of the upper Nile, and resulted in both a doctorate (in 1927) and his classic Witchcraft, Oracles and Magic Among the Azande (in 1937). In 1930, he began a new research project among the Nuer. During the Second World War Evans-Pritchard served in Ethiopia, Libya, Sudan, and Syria. In Sudan, he raised irregular troops among the Anuak to harass the Italians and engaged in guerrilla warfare. In 1942 he was posted to North Africa. He became one of a few English-language authors to write about the tariqa. He donated his photographic collection from his travels to the Pitt Rivers Museum in 1966.
