Excerpt from Cyclopedia of Applied Electricity, Vol. 7 of 7: A General Reference Work on Direct-Current Generators and Motors, Storage Batteries, Electrochemistry, Welding, Electric Wiring, Meters, Electric Lighting, Electric Railways, Power Stations, Switchboards, Power Transmission, Etc Steinheil Telegraph. Steinheil was engaged by Gauss to develop apparatus which had been invented by Gauss and Webber. The transmitter being of the magneto type required no battery but pro duced impulses of current, alternating in polarity, by the movement back and forth of a strong permanent magnet. The original Gauss Webber receiver was practically Webber's mirror galvanometer, which would deflect a beam of light to the right or left according to the polarity of the impulse generated by the transmitter. A given number of swings in each direction represented the various letters of the alphabet. Steinheil made several improved forms of receivers, including an ink writing recorder. This telegraph required only one circuit and it appears to have operated satisfactorily over short lines but was not successfully operated over long lines.
