Harris was born in Treherbert, Wales. As a young man he joined the army as World War I (1914-18) began. He married in 1928 and in the 1930s was introduced to Spiritualism. He attended séances with the fraud medium Helen Duncan which he was convinced were genuine. After attending other séances he became a medium himself and claimed the ability to materialize spirit guides. Harris would only work in dark conditions with a cabinet in a curtained-off alcove from his audience where the spirits were reported to emerge.
In the 1940s it was stated by spiritualists that he could materialize as many as 15 to 30 spirits in a single séance. He later moved to South Africa to resume a career as a medium. He conducted séances until his death in 1974. He died on February 12, 1974, in Johannesburg. His wife, Louie Harris, wrote a biography of him after his death.
In January 1955, Tony Cornell attended a séance to investigate the mediumship of Harris. In the séance Harris sat behind a curtain cabinet and in total eleven "spirit" figures came out from behind the curtain at different times dressed in different clothing. They walked around the room, communicated with the sitters to then disappear behind the curtain. The room was in complete darkness apart from some dim light in the middle of the room.
Cornell noted that all the figures had a similar stature, they dressed similarly but used different masks and hats. Only one figure came out from the curtain at a time and only minutes after each other. According to the sitters who had touched the figures, their skin felt coarse and rough even though some were supposed to be female. Cornell wrote that a stomach rumble, nicotine smelling breath and a pulse gave it away that all the figures were in fact Harris and that he had dressed up as each one behind the cabinet. The cabinet was not examined before or after the sitting and Harris refused to be searched before or after the sitting.
The spirit figures were also reported to creak and move floor boards as they walked on them, indicating that they were human.
