A small British psychical research organization founded specifically to develop a mechanical apparatus for communication with the spirits of the dead. It was named for the founders A. J. Ashdown, B. K. Kirby, and George Jobson, who were somewhat obsessed with scientifically proving survival of bodily death and made a pact that whoever passed away first would attempt to communicate with the other two in the form of a brief message. Jobson died in 1930, and three months later the confidential message was received through a MEDIUM who was not formerly acquainted with any of the three. After Ashdown and Kirby established a relationship with the medium, Mrs. L. E. Singleton, Job- son, supposedly speaking through Singleton, gave the instructions for constructing various instruments to facilitate communication.
The Ashkir-Jobson Trianion Guild was founded to construct and market the several instruments described by Jobson. Among these were the Ashkir-Jobson vibrator, which produced a continuous musical tone for the purpose of creating a harmonious atmosphere at seances. It operated by clockwork and could send out a steady sound for up to three hours. The device activated an A-note tuning fork. Other instruments for actual communication were termed the communigraph and the reflectograph.
