After his son’s death in 1918, Dr. Thomas Glendenning Hamilton began to experiment with psychic phenomena, investigating paranormal occurrences such as rappings, psychokinesis, ectoplasms, trance states, psychic phenomena, and apparitions. He conducted his experiments under scientific conditions that he believed would minimize errors and expose hoaxes. His work became known throughout Europe as well as the United States.
