Breakthrough: An Amazing Experiment in Electronic Communication With the Dead by Konstantin Raudive, Ph.D

Translated by Nadia Fowler, edited by Joyce Morton, with a Preface by Peter Bander. This book is the documented result of six years' arduous research into an astounding scientific phenomenon, accidentally discovered in Sweden by Friedrich Jurgenson in 1957. In some way, and for reasons not yet fully understood, voices of dead persons linked by affection or interest with the experimenter appear during playbacks of tape recordings on which no such voices were audible at the time of the original recording. These voices always state their names and may be identified as male or female, but all speak very much faster than is normal and employ a curious speech rhythm. In the course of his research, Dr Raudive was joined by eminent scientists, physicists, psychologists, and theologians, many of whom were university professors. Before undertaking the publication of this English-language edition, the publishers have requested other respected scientists and scholars to verify procedures and findings related in Dr Raudive's book. The discovery of this phenomenon - later called the Electronic Voice Phenomenon - is a breakthrough of unquestionable importance.
