Sir Arthur Keith FRS FRAI was a British anatomist and anthropologist, and a proponent of scientific racism. He was a fellow and later the Hunterian Professor and conservator of the Hunterian Museum of the Royal College of Surgeons of England. He was a strong proponent of the Piltdown Man, but conceded it to be a forgery shortly before his death.

The Royal Anthropological Institute of Great Britain and Ireland (RAI) is a long-established anthropological organisation, and Learned Society, with a global membership. Its remit includes all the component fields of anthropology, such as biological anthropology, evolutionary anthropology, social anthropology, cultural anthropology, visual anthropology and medical anthropology, as well as sub-specialisms within these, and interests shared with neighbouring disciplines such as human genetics, archaeology and linguistics. It seeks to combine a tradition of scholarship with services to anthropologists, including students.
