Maria Silbert

Silbert was born in Waltendorf, Graz and claimed powers of apportation and psychokinesis as well as the ability to produce "spirit raps".

The psychical researcher Eric Dingwall in a review wrote that "as a work of scientific interest it is worthless, but as illustrating the minds of those over whom Frau Silbert cast her influence it is by no means without value.

"[3] In 1925, the British psychical researcher Harry Price investigated Silbet and caught her using her feet and toes to move objects in the séance room.

She had developed the ability to maneuver a stiletto using only her feet and was thus able to write names on the cigarette cases when they were held under the table.

[1] Another researcher Theodore Besterman investigated Silbert in 1928 and observed that the "spirit raps" only occurred when Silbert had her legs under the table or in front of the chair which suggested that she tapped the furniture herself with her feet to make the sounds.
