There is no RationalWiki without you. We are a small non-profit with no staff – we are hundreds of volunteers who document pseudoscience and crankery around the world every day. We will never allow ads because we must remain independent. We cannot rely on big donors with corresponding big agendas. We are not the largest website around, but we believe we play an important role in defending truth and objectivity.
If everyone who saw this today donated $5, we would meet our goal for 2019.

Crandon grew up on a farm in Canada but moved to Boston as a young woman. She married Earl Rand, a grocer. They had one son. She later met Dr. LeRoi Goddard Crandon when she entered a Dorchester, Massachusetts, hospital for an operation. Dr. Crandon was her surgeon. She later divorced Rand and married Crandon.
Her second husband Dr. Crandon, was a wealthy Boston physician and professor of surgery at Harvard. Both Crandon and her husband took interest in spiritualism and took part in seances. She claimed to be able to contact her deceased brother Walter by mediumship and her seances were widely reported, causing much publicity and controversy.
Crandon died an alcoholic in 1941.
Crandon was a famous medium in the 1920s known for producing ectoplasm during her seance sittings. She produced a small ectoplasmic hand from her stomach which waved about in the darkness. Her career ended however when biologists examined the hand and found it to be made of a piece of carved animal liver. The escape artist Harry Houdini had also exposed the mediumship tricks of Crandon.
Crandon also claimed to produce wax impressions of spirit fingerprints but was exposed as a fraud as she had been using moulds of fingerprints from her living dentist Dr. Kerwin and pretended in the seance room that they were spirit fingerprints from her deceased brother Walter. According to Zusne and Jones (1989), "When in 1932 it was discovered that the spirit fingerprints left behind on a piece of wax (spirit fingerprints had become a specialty of Margery's) were those of Margery's dentist, very much alive, rather than those of Walter, the Boston Society for Psychical Research published a report on it, describing Margery as the most ingenious and persistent fraud in the annals of psychical research."
The Italian skeptic Massimo Polidoro has written an article that has documented the fraud of Crandon.
Crandon's husband was known for displaying nude photographs of her in her mediumship sessions. Mina Crandon was described as a very beautiful lady who men found "too attractive for her own good". Psychical investigator Malcolm Bird was actively conspiring with the Crandon's in stage-managing the seances in an attempt to have a sexual relationship with Mina. Reports however, suggest that Mina found Bird repulsive. Instead she held amorous affections for the psychical researcher Hereward Carrington with whom she had an affair.
