Zierold, Maria Reyes
A Mexican sensitive who was the subject of experiments by
Gustav Pagenstecher (1855–1942) from about 1919 onward.
Zierold was a housewife whom Pagenstecher treated for insomnia
by means of hypnosis. To his surprise, Zierold manifested
psychometric ability while in hypnotic trance.
A medical committee in Mexico City also examined
Zierold’s abilities and reported that the phenomena seemed
genuinely paranormal. In 1921 Walter Franklin Prince, then
principal research officer of the American Society for Psychical
Research visited Mexico to observe Pagenstecher’s experiments
and to conduct his own. He reached similar conclusions.
