Some scientists of the period who investigated Spiritualism also became converts. They included chemist Robert Hare, physicist William Crookes (1832–1919) and evolutionary biologist Alfred Russel Wallace (1823–1913). Nobel laureate Pierre Curie took a very serious scientific interest in the work of medium Eusapia Palladino. Other prominent adherents included journalist and pacifist William T. Stead (1849–1912) and physician and author Arthur Conan Doyle (1859–1930).
Psychic mediums have the ability to sense and communicate with beings and energies in other dimensions, including the spirits of people who have died. They are often called upon to help people who have unresolved questions for loved ones who have passed away. Psychic mediums may use meditative channeling, palmistry, psychometric, or readings from tarot cards or crystal balls to facilitate communication with those in other dimensions. This article includes information on what it means to be a psychic medium, how to improve your psychic abilities, and how to use your abilities in the service of others, whether they be people or spirits.
Physical mediumship is defined as manipulation of energies and energy systems by spirits. This type of mediumship is claimed to involve perceptible manifestations, such as loud raps and noises, voices, materialized objects, apports, materialized spirit bodies, or body parts such as hands, legs and feet. The medium is used as a source of power for such spirit manifestations. By some accounts, this was achieved by using the energy or ectoplasm released by a medium, see spirit photography. The last physical medium to be tested by a committee from Scientific American was Mina Crandon in 1924.
On Fox News on the Geraldo at Large show, October 6, 2007, Geraldo Rivera and other investigators accused Schwartz as a fraud as he had overstepped his position as a university researcher by requesting over three million dollars from a bereaved father who had lost his son. Schwartz claimed to have contacted the spirit of a 25-year-old man in the bathroom of his parents house and it is alleged he attempted to charge the family 3.5 million dollars for his mediumship services. Schwartz responded saying that the allegations were set up to destroy his science credibility.
According to the magician John Booth the stage mentalist David Devant managed to fool a number of people into believing he had genuine psychic ability who did not realize that his feats were magic tricks. At St. George's Hall, London he performed a fake "clairvoyant" act where he would read a message sealed inside an envelope. The spiritualist Oliver Lodge who was present in the audience was duped by the trick and claimed that Devant had used psychic powers. In 1936 Devant in his book Secrets of My Magic revealed the trick method he had used.
Humans have been fascinated with contacting the dead since the beginning of human existence. Cave paintings by indigenous Australians date back 28,000 years, some depicting skulls, bones, spirits and the afterlife. Other cave paintings in Indonesia date back a further 10,000 years. Mediumship gained popularity during the nineteenth century, when ouija boards were used by the upper classes as a source of entertainment. Investigations during this period revealed widespread fraud—with some practitioners employing techniques used by stage magicians—and the practice began to lose credibility. Fraud is still rife in the medium/psychic industry, with cases of deception and trickery being discovered to this day.
