The Submarine Telegraph Company was a British company which laid and operated submarine telegraph cables.
Jacob and John Watkins Brett formed the English Channel Submarine Telegraph Company to lay the first cable across the English Channel. An unarmoured cable with gutta-percha insulation was laid in 1850. The recently introduced gutta-percha was the first thermoplastic material available to cable makers and was resistant to seawater. This first unarmoured cable was a failure and was soon broken either by a French fishing boat or by abrasion on the rocks off the French coast.
The Bretts formed a new company, the Submarine Telegraph Company, and laid a new cable in 1851. This cable had multiple conductors and iron wire armouring. Telegraph communication with France was established for the first time in October of that year. This was the first undersea telegraph cable to be put in service anywhere in the world.
The Company continued to lay, and operate, more cables between England and the Continent until they were nationalised in 1890. Through a series of mergers they ultimately became part of Cable and Wireless (CW). The Times commemorated the 50th anniversary of the cable in 1900; CW and the Science Museum, London did the same on the 100th anniversary in 1950.
