Since the age of seventeen, Dr. Tenhaeff has been interested in the whole field of parapsychology. He has investigated and reported on spontaneous cases of psychometry, clairvoyance, precognition, unorthodox healing; and on the use of the divining rod, and the structure of personality. Since the founding of the Parapsychology Institute at Utrecht University, he has specialized in the study of the personality structure of sensitives. His lectures on parapsychology have taken him to Norway, Sweden, Germany, Belgium, Switzerland, Austria and Italy, and, before World War II, to Czechoslovakia and Hungary. His articles have appeared in Tijdschrift voor Parapsychologie, Tomorrow magazine, and other journals devoted to psychical research.
