British Electric Telegraph Company
In the nineteenth century, the United Kingdom had the world's first commercial telegraph company. British telegraphy dominated international telecommunications well into the twentieth. Telegraphy is the sending of textual messages by human operators using symbolic codes. Electrical telegraphy used conducting wires to send messages, often incorporating a telegram service to deliver the telegraphed communication from the telegraph office. This is distinct from optical telegraphy that preceded it and the radiotelegraphy that followed. Though Francis Ronalds first demonstrated a working telegraph over a substantial distance in 1816, he was unable to put it into practical use. Starting in 1836, William Fothergill Cooke, with the scientific assistance of Charles Wheatstone, developed the Cooke and Wheatstone telegraph. The needle telegraph instrument suggested by Wheatstone, the battery invented by John Frederic Daniell, and the relay invented by Edward Davy were import ...

Electric Telegraph Company
The Electric Telegraph Company (ETC) was a British telegraph company founded in 1846 by William Fothergill Cooke and John Ricardo. It was the world's first public telegraph company. The equipment used was the Cooke and Wheatstone telegraph, an electrical telegraph developed a few years earlier in collaboration with Charles Wheatstone. The system had been taken up by several railway companies for signalling purposes, but in forming the company Cooke intended to open up the technology to the public at large. The ETC had a monopoly of electrical telegraphy until the formation of the Magnetic Telegraph Company (commonly called the ''Magnetic'') who used a different system which did not infringe the ETC's patents. The Magnetic became the chief rival of the ETC and the two of them dominated the market even after further companies entered the field. The ETC was heavily involved in laying submarine telegraph cables, including lines to the Netherlands, Ireland, the Channel Islands ...

Eastern Telegraph Company
Cable & Wireless plc was a British telecommunications company. In the mid-1980s, it became the first company in the UK to offer an alternative telephone service to British Telecom (via subsidiary Mercury Communications). The company later offered cable TV to its customers, but it sold its cable assets to NTL in 2000. It remained a significant player in the UK telecoms market and in certain overseas markets, especially in the former British colonies of the Caribbean, where it was formerly the monopoly incumbent. It was also the main supplier of communication in the British South Atlantic, including Saint Helena and the Falkland Islands. It was listed on the London Stock Exchange and was a constituent of the FTSE 100 Index. The company split in March 2010, with its international division demerging to form Cable & Wireless Communications, acquired by Liberty Global in 2015, and since spun-off in 2018 from Liberty Global to Liberty Latin America, while the remainder of the Cable & W ...

Atlantic Telegraph Company
The Atlantic Telegraph Company was a company formed on 6 November 1856 to undertake and exploit a commercial telegraph cable across the Atlantic ocean, the first such telecommunications link. History Cyrus Field, American businessman and financier, set his sights on laying the first transatlantic underwater telegraph cable after having been contacted by Frederic Newton Gisborne who attempted to connect St. Johns, Newfoundland to New York City, but failed due to lack of funding. After inquiring about the feasibility of a transatlantic underwater cable to Lieutenant Matthew Fontaine Maury of the U.S. Navy, Field formed an agreement with the Englishmen John Watkins Brett and Charles Tilston Bright to create the Atlantic Telegraph Company. It was incorporated in December, 1856 with £350,000 capital, raised principally in London, Liverpool, Manchester, and Glasgow. The board of directors was composed of eighteen members from the United Kingdom, nine from the United States, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transatlantic Telegraph Cable
Transatlantic telegraph cables were undersea cables running under the Atlantic Ocean for telegraph communications. Telegraphy is now an obsolete form of communication, and the cables have long since been decommissioned, but telephone and data are still carried on other transatlantic telecommunications cables. The first cable was laid in the 1850s from Valentia Island off the west coast of Ireland to Bay of Bulls, Trinity Bay, Newfoundland. The first communications occurred on 16 August 1858, but the line speed was poor, and efforts to improve it caused the cable to fail after three weeks. The Atlantic Telegraph Company led by Cyrus West Field constructed the first transatlantic telegraph cable. The project began in 1854 and was completed in 1858. The cable functioned for only three weeks, but was the first such project to yield practical results. The first official telegram to pass between two continents was a letter of congratulations from Queen Victoria of the United ...

Submarine Telegraph Company
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 Engla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gutta-percha
Gutta-percha is a tree of the genus ''Palaquium'' in the family Sapotaceae. The name also refers to the rigid, naturally biologically inert, resilient, electrically nonconductive, thermoplastic latex derived from the tree, particularly from ''Palaquium gutta''; it is a polymer of isoprene which forms a rubber-like elastomer. The word "gutta-percha" comes from the plant's name in Malay: ''getah'' translates as "latex". ''Percha'' or ''perca'' is an older name for Sumatra. Description ''P. gutta'' trees are tall and up to in trunk diameter. The leaves are evergreen, alternate or spirally arranged, simple, entire, long, glossy green above, and often yellow or glaucous below. The flowers are produced in small clusters along the stems, each flower with a white corolla with four to seven (mostly six) acute lobes. The fruit is an ovoid berry, containing one to four seeds; in many species, the fruit is edible. In Australia, gutta-percha is a common name specifically used for ...

William Montgomerie
William Montgomerie (1797–1856) was a Scottish military doctor with the East India Company, and later head of the medical department at Singapore. He is best known for promoting the use of gutta-percha in Europe. This material was an important natural rubber that made submarine telegraph cables possible. Montgomerie was involved in spice cultivation as head of the Singapore botanical experimental gardens and at his personal estate in Singapore. The latter never became economically viable, but he received a Society of Arts gold medal for nutmeg cultivation. He was also responsible for building the first lunatic asylum in Singapore. Montgomerie died at Barrackpore in India a few years after taking part in the Second Anglo-Burmese War as Superintendent Surgeon. Early life and family Montgomerie was born in Scotland in 1797. In 1827, he married Elizabeth Graham in Calcutta. A son is mentioned in a newspaper article. His brother was Major-General Sir P. Montgomerie of the Ma ...

Great Britain
Great Britain is an island in the North Atlantic Ocean off the northwest coast of continental Europe. With an area of , it is the largest of the British Isles, the largest European island and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The 60% smaller island of Ireland is to the west—these islands, along with over 1,000 smaller surrounding islands and named substantial rocks, form the British Isles archipelago. Connected to mainland Europe until 9,000 years ago by a landbridge now known as Doggerland, Great Britain has been inhabited by modern humans for around 30,000 years. In 2011, it had a population of about , making it the world's third-most-populous island after Java in Indonesia and Honshu in Japan. The term "Great Britain" is often used to refer to England, Scotland and Wales, including their component adjoining islands. Great Britain and Northern Ireland now constitute the ...

Submarine Telegraph Cable
A submarine communications cable is a cable laid on the sea bed between land-based stations to carry telecommunication signals across stretches of ocean and sea. The first submarine communications cables laid beginning in the 1850s carried telegraphy traffic, establishing the first instant telecommunications links between continents, such as the first transatlantic telegraph cable which became operational on 16 August 1858. Subsequent generations of cables carried telephone traffic, then data communications traffic. Modern cables use optical fibre technology to carry digital data, which includes telephone, Internet and private data traffic. Modern cables are typically about in diameter and weigh around for the deep-sea sections which comprise the majority of the run, although larger and heavier cables are used for shallow-water sections near shore. Submarine cables first connected all the world's continents (except Antarctica) when Java was connected to Darwin, Northern Terri ...
