These photomicrographs are from the personal scrapbook of Nandor Fodor. The attached caption reads, “The disputed fingerprints of Walter and Margery’s dentist.” During a sitting, “Walter” was said to produce a fingerprint (shown on the left) in dental wax. However, in 1935, the American Society for Psychical Research announced that the resulting fingerprint was a near-identical match to that of Crandon’s dentist (shown on the right), who had been present during the sitting. This evidence fueled existing skepticism of Crandon’s abilities.
