Title: TELEGRAPHY, SUBMARINE.
Authors: Hempstead, Colin A.1
Source: Encyclopedia of Electrical & Electronics Engineering. 1999 1st Edition, Vol. 21, p470-480. 11p.
Subjects: Submarine cables, Electric wiring, Telegraph lines, Radioactive substances in rivers, lakes, etc., Radioactive pollution of water, Radioactive waste disposal in rivers, lakes, etc.
Abstract: This article presents information regarding submarine telegraphy. Experiments to send electrical signals along insulated conductors submerged in rivers and lakes began during the 1800's and were successful, but commercial subaqueous telegraph lines were not feasible in the absence of a sufficiently reliable insulating material. By the middle of the 19th century London, the foremost commercial capital of the major manufacturing nation, was not in telegraphic contact with other important centers. To remedy this shortcoming, Jacob and John Brett, British entrepreneurs, determined to lay a telegraph line from Dover in England to Cap Gris Nez in northern France.
