Helen Duncan was one of the most controversial spiritualists of the twentieth century. Born in Scotland in 1897, she became famous for claiming that she could communicate with the dead. During the early decades of the twentieth century, spiritualism attracted many followers, especially after the First World War, when thousands of grieving families hoped to contact lost relatives. Helen Duncan quickly gained attention because of her dramatic séances, in which she claimed spirits appeared physically before audiences.
Many people believed in her abilities, but others accused her of fraud. Investigators argued that the “ectoplasm” she produced during séances was made from ordinary materials such as cloth or paper. Despite criticism, Duncan continued to attract supporters who believed she possessed genuine supernatural powers. Her séances often created excitement and curiosity across Britain.
Helen Duncan became widely known during the Second World War. In 1941, she reportedly revealed information about the sinking of the British battleship HMS Barham before the news had been officially announced. Authorities feared that she might reveal military secrets or damage wartime morale. In 1944, she was arrested during a séance in Portsmouth and charged under the Witchcraft Act of 1735. This old law had originally been created to punish people pretending to use magical powers.
Her trial attracted considerable public attention. Duncan was found guilty and sentenced to nine months in prison, becoming the last person in Britain to be imprisoned under the Witchcraft Act. The case caused debate about freedom of belief and the fairness of using an outdated law in modern society. In 1951, the Witchcraft Act was repealed and replaced with the Fraudulent Mediums Act.
Helen Duncan died in 1956, but her story remains fascinating today. Some people still view her as a genuine medium who was unfairly treated, while others consider her an entertainer who deceived the public. Regardless of opinion, Helen Duncan remains an important figure in the history of spiritualism and British law.
