The search for Sir John Franklin (1847–59) coincided with a growing interest in mesmerism and modern spiritualism in Britain. Several clairvoyants, claiming to ‘see’ Franklin's ships and crews in the Arctic, made statements about the status and location of the overdue expedition, and at least three mediums described communications with Franklin’s spirit. Although the Admiralty provided assistance to Dr Haddock, the mesmerist of Emma, the Bolton clairvoyant, they did not take any action on the basis of her statements, probably because the various accounts were contradictory and could not be verified, and because the Admiralty Lords were sceptical of paranormal phenomena. Lady Franklin, on the other hand, visited clairvoyants and altered the plans for her search expeditions under Forsyth and Kennedy on the basis of a revelation. Recently, an American medium has described more than two dozen conversations with the spirits of Sir John and Lady Franklin.
