The Fox Brothers, who founded the first professional mediumship business in 1848, have an interesting place in the history of spiritualism. In 1848, when Margaret was 14 and Kate was 10, they moved to a house in New York with their families. It's been a few months since they moved, when one night the whole family is startled by strange noises coming from the house. The mother of the house wants her daughters to sleep with them now that these noises continue on other nights.

They tell their neighbors about their experiences and now the house becomes a "haunted house" in the eyes of everyone. Even from France, people who say they are "psychologists" come to the family's house and want to do research and even dig under the house. Now these rumors get so big that even news is made.

The girls say that there is a spirit in the house and that they are talking to him, and his name is "Mr. Splitfool". There is another interesting situation when Kate suddenly warns everyone to be quiet while everyone's eyes are on her, and strange noises begin to come from the wooden house. In the news in the newspapers, it is written that the spirit that the girls spoke belongs to the traveler named Charles B. Rosna, who was killed five years ago. Even the writer Arthur Conan Doyle, the creator of the character of Sherlock Holmes, says that the bottom of the house was dug and bone fragments were found in his articles about these girls at that time.

The girls' fathers decide to move from here and change their homes, but when they hear the same voices in the new house they go to, mother Fox is completely convinced that their daughter can talk to spirits. After this moment, the girls' older sister Leah steps in and plans to make money from this business. Thus, on November 14, 1849, a psychic show was presented to ticketed customers for the first time in world history in the Hall of Corinth. This date is also a turning point for the spiritualism movement in the USA.

When we come to 1850, they have become one of the most famous people of the time, and now the psychic sisters and even the famous politicians, men of letters and scientists of the time come to the shows they organize in New York. But in 1851, a relative of the girls made a confession and said that he made the sounds from behind the stage during the performances. Later, a team of doctors examines the girls and realizes that by pretending to crack their toes, they make sounds that a normal person cannot make.

Is there a trick? Confessions come from the psychic brothers. They say that in the first house they moved in, they tied the apple to a rope and moved it even though they were lying in their beds, and that's how they made the sounds in the house. They state that there was no corpse or spirit in the second house they moved to, but people wanted to believe it. In fact, some of these curious people found a poor man named Bell, who lived in the haunted house before the Fox Family, and accused him of being a murderer.

Kate, one of the psychic sisters who can no longer perform, marries a wealthy banker and goes to England. He has two sons. But after his wife died, he returned to New York and died as an alcoholic in 1892. A year after Kate, her sister Margaret dies from excessive alcohol consumption. Despite all these confessions, most people continue to believe that psychic sisters communicate with spirits. In fact, until their death, they received various offers from many sects and organizations in the USA to act with them.

However, in the last days of their lives, they also made violent statements against psychology. Kate even withdrew her confessions and writings against spiritualism after backlash from spiritualists. The houses of the psychic sisters in New York have been visited by spiritualists for a long time as a museum.
