Victoria Helen McCrae Duncan (née MacFarlane, 25 November 1897 – 6 December 1956) was a Scottish medium best known as the last person to be imprisoned under the Witchcraft Act 1735 (9 Geo. 2. c. 5) for fraudulent claims. She was famous for producing ectoplasm which was proved to be made from cheesecloth.[1][2][3][4]
