From the accounts of Thomas Edison's experiments with the "necrophone" or "necrophonic device," it is interesting to note that his work on this device is often intertwined with facts and legends.
 Among the first experiments, Edison and his team used a device called a "spirit receiver." This device was supposed to detect the presence of spirits or supernatural manifestations. One notable experiment involved an Edison light bulb. Here's how these experiments unfolded:
 Edison designed the "spirit receiver" to pick up signals or vibrations that spirits might produce. The exact operation of this device remains unclear, but the idea was for it to be sensitive to changes imperceptible to the human ear or standard instruments of the time. The device was connected to a light bulb, a signature invention of Thomas Edison. The experiment involved observing the bulb to see if it lit up in response to spirit activity or messages from the beyond.
 In one such test, Edison and his colleagues reportedly installed the spirit receiver in a dark room conducive to spiritual manifestations. The bulb was carefully monitored. At one point, the bulb reportedly began to glow dimly, suggesting that the spirit receiver had picked up some sort of signal or spiritual presence.
 This experiment reportedly gave Edison hope that his necrophone project could indeed enable communication with the dead. However, like many other stories related to paranormal research, the details and results of these trials are often disputed and shrouded in mystery.
 Edison, known for his pragmatism and scientific approach, never published conclusive evidence on the effectiveness of his necrophonic devices. The necrophone project therefore remains a historical curiosity, a blend of science, spirituality, and fascination with the unknown.
 JACK THE RIPPER
 The story of Catherine Eddowes, one of Jack the Ripper's most famous victims, is tragic and mysterious, and has given rise to numerous legends and paranormal tales.
 Catherine Eddowes and Jack the Ripper
 Catherine Eddowes is one of the five so-called "canonical" victims of Jack the Ripper, the notorious serial killer who terrorized the streets of Whitechapel, London, in 1888. She was murdered on the night of September 29-30, 1888, in Mitre Square. Her murder was particularly brutal, with gruesome mutilations that shocked Victorian society. Investigations never revealed the killer's identity, and her case remains one of the most fascinating mysteries in criminal history.
 Edison's Apparatus and Spiritism
 The Legend of the Spiritist Circle and Catherine Eddowes
 This spiritualist group, composed of mediums and fervent believers in spiritualism, is said to have used an electrical device, powered by a light bulb, to communicate with spirits.
 According to the story, the light bulb only lit up when Catherine Eddowes's spirit was present. The mediums allegedly interpreted this signal as tangible evidence that her soul was trying to contact them. Messages dictated by Catherine's spirit would arrive through the device, revealing details about her murder or her life, creating a regular connection with the afterlife. These sessions with the device would have reinforced the idea that Catherine was still seeking to share her story and solve the mystery of her murderer.
 In some variations of this legend, Catherine's spirit is said to have appeared regularly, with the bulbs lighting up more brightly when she attempted to convey more urgent or personal messages, including details about the circumstances of her death. The device used during these séances is said to have served as a "portal" between the worlds of the living and the dead, creating a kind of constant connection between this spirit circle and Catherine.
