- In 1886 the paranormal researchers and founders of the Society for Psychical Research (SPR) Edmund Gurney (1847-1888), Frederic Myers (1843-1901), and Frank Podmore (1856-1910) defined hallucinations as "percepts which lack, but which can only by a distinct reflection be recognized as lacking, the objective basis which they suggest".ReferencesGurney, E., Myers, F.W.H., Podmore, F.
