Transcontinental Telegraph Line (U.S.) The first transcontinental telegraph line was built in 1861 by the Western Union Telegraph Company. The line extended from Omaha, Nebraska to Carson City, Nevada and was the first high-speed link between California and the rest of the United States. It reached the West Coast eight years in advance of the transcontinental railroad.

- Morse came rather late to the development of telegraphy, although he had always expressed an interest in the science of electricity. First invented in 1774, the telegraph was a bulky and impractical machine that was designed to transmit over twenty-six electrical wires.

Antique glass insulators Background. Antique glass insulators were designed in the early 1800s as a means of insulating early communication wires. Their production spans more than 100 years-a period punctuated by changed in design and use. In 1844, Morse's first telegraph line was installed between Baltimore and Washington.ntique glass insulators were an early means of insulating communication wires. They are often discovered alongside (disused) railway tracks. Although the practice of collecting antique glass insulators only dates back approximately fifty years, it is a very popular pastime, particularly in the United States.

Transatlantic telegraph cable In the 1840s and 1850s several individuals proposed or advocated construction of a telegraph cable across the Atlantic Ocean, including Edward Thornton and Alonzo Jackman. Cyrus West Field and the Atlantic Telegraph Company were behind the construction of the first transatlantic telegraph cable.efore the first transatlantic cable, communications between Europe and the Americas took place only by ship. Sometimes, however, severe winter storms delayed ships for weeks. The transatlantic cable reduced communication time considerably, allowing a message and a response in the same day.

- History [edit]. Early telegraph systems used the first forms of electrical cabling, transmitting tiny amounts of power. Gutta-percha insulation used on the first submarine cables was, however, unsuitable for building wiring use since it deteriorated rapidly when exposed to air.istory [edit].

Technological and industrial history of the United States Prior to the Industrial Revolution, which began in Britain in the late 1700s, manufacturing was often done in people’s homes, using hand tools or basic machines.ommunication became easier during the Industrial Revolution with such inventions as the telegraph. In 1837, two Brits, William Cooke (1806-1879) and Charles Wheatstone (1802-1875), patented the first commercial electrical telegraph.

Electrical telegraph The electrical telegraph, or more commonly just telegraph, superseded optical semaphore telegraph systems, such as Claude Chappe 's cables designed for communication among the French military, and Friedrich Clemens Gerke for the Prussian military, thus becoming the first form of electrical telecommunications.

Samuel Morse Around that time, two German engineers had invented a five-wire model, but Morse wanted to be the first to reduce the number of wires used to one. Between 1832 and 1837, he developed a working model of an electric telegraph, using crude materials such as a home-made battery and old clock-work gears.

Telegraph Telegraph: Telegraph, any device or system that allows the transmission of information by coded signal over distance. Many telegraphic systems have been used over the centuries, but the term is most often understood to refer to the electric telegraph, which was developed in the mid-19th century and for more than 100 years was the principal means of transmitting printed information by wire or radio wave.

- The word telegraph was first coined by the French inventor of the Semaphore line, Claude Chappe, who also coined the word semaphore. A telegraph is a device for transmitting and receiving messages over long distances, i.e., for telegraphy. The word telegraph alone now generally refers to an electrical telegraph.

Samuel Morse In time the Morse code, which he developed, would become the primary language of telegraphy in the world. It is still the standard for rhythmic transmission of data. Meanwhile, William Cooke and Professor Charles Wheatstone had learned of the Wilhelm Weber and Carl Gauss electromagnetic telegraph in 1833.

The History of the Electric Telegraph and Telegraphy The electric telegraph is a now outdated communication system that transmitted electric signals over wires from location to location that translated into a message. The non-electric telegraph was invented by Claude Chappe in 1794. This system was visual and used semaphore, a flag-based alphabet, and depended on a line of sight for communication. The optical telegraph was replaced by the electric telegraph, the focus of this article. In 1809, a crude telegraph was invented in Bavaria by Samuel Soemmering. He used 35 wires with gold electrodes in water and at the receiving end 2000 feet the message was read by the amount of gas caused by electrolysis.
