Between 1909 and 1915, N. W. Thomas conducted four extensive anthropological surveys in West Africa: three in areas corresponding with parts of present day Edo, Delta, Anambra and Enugu states in Southern Nigeria, and one in mainly northern Sierra Leone. We have reconstructed Thomas’s itineraries from fieldnotes, letters and information associated with his photographs, sound recordings and collections.
