O. Jim Ellis was a researcher of the spiritualist and paranormal. Ellis spent six decades documenting the sittings of direct-voice medium Leslie Flint. Ellis passed away on September 17, 2013.

Leslie Flint was one of Britain's most well know spiritualists. Born in 1911 Flint stated that he first encountered the dead at the age of eight when he saw the solid figure of his deceased uncle standing in his grandmother's kitchen. Later in life Flint utilized his gift as a direct-voice medium where the deceased would speak in their own voices from space just outside of Flint's body. Many people felt that celebrities and ordinary people alike spoke through Leslie Flint. Sittings were conducted in the dark ostensibly because Flint emitted ectoplasm which would form an "etheric voice-box" through which the dead would speak. Flint was tested repeatedly to verify the legitimacy of his performances. He held water in his mouth during seances, and made use of a throat microphone which demonstrated that no vibrations were emitted from his voice box to deny claims of ventriloquism. Flint died in 1994.
