Medium practices for many years have been the lot of a few representatives who were famous for their aristocracy and education. And only in the nineteenth century such a concept as spiritualism became widely known. Oddly enough, but the developers of fairly simple and well-known devices throughout the world were not famous scientists, but ordinary Americans. It was from them that such a hobby as spiritualism spread throughout the New and Old Worlds. These ordinary Americans were the Fox sisters. Let's turn to history and take a look at the nineteenth century.
In 1848, the rather ordinary Fox family, consisting of mom, dad and two daughters, began to hear strange knocks at night. While the older generation was looking for the culprit among the poorly fixed doors, sash windows and pets, their youngest daughter Kat shared with her sister the assumption that these sounds are not random, but are made by their intelligent creature. The girls decided to take a chance and try to establish contact with their unexpected guest. A rather simple scheme was chosen for communication: one knock meant “No”, and three quick ones - “Yes”. As a result, the sisters managed to find out that the spirit that settled in their house is the spirit of the peddler who was killed. He described in great detail the scene of his death and told the girls such details that could not be accessible to the general public. The spirit of the deceased turned out to be very sociable:he was always in contact with the Fox sisters without fail. This continued even after they left their parents' home.
Not surprisingly, conversations about the girls' unusual abilities very quickly spread to the entire district, and then the continent. This was facilitated by people who attended the Fox sisters' home sessions of spiritualism and who understood the value of this phenomenon in science.
Officially, girls were recognized as "natural phenomena, mediators between two worlds", mediums who help people create contact with the other world.
