Samuel Finley Breese Morse (April 27, 1791 – April 2, 1872) was an American inventor and painter. After having established his reputation as a portrait painter, in his middle age Morse contributed to the invention of a single-wire telegraph system based on European telegraphs.
According to Morse, telegraph dates only from 1832 when Pavel Schilling invented one of the earliest electrical telegraphs. [ 3 ] A telegraph message sent by an electrical telegraph operator or telegrapher using Morse code (or a printing telegraph operator using plain text) was known as a telegram.
Morse code. Morse code is a telecommunications method which encodes text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs. [ 3][ 4] Morse code is named after Samuel Morse, one of the early developers of the system adopted for electrical telegraphy .
The archetype of this category was the Morse system and the code associated with it, both invented by Samuel Morse in 1838. In 1865, the Morse system became the standard for international communication, using a modified form of Morse's code that had been developed for German railways.
Samuel Morse's first experimental line between Washington, D.C., and Baltimore—the Baltimore-Washington telegraph line—was demonstrated on May 24, 1844. [3] By 1850 there were lines covering most of the eastern states, [ 4 ] and a separate network of lines was soon constructed in the booming economy of California.
The telegraph represented a disruptive innovation in the history of the United States from its invention in the 1830s onward by quickly becoming a vital part of the nation's communication infrastructure. Its relative importance declined with the spread of telephones in the 20th century. Telegraph service permitted short texts to be sent cheaply ...
A telegraph code is one of the character encodings used to transmit information by telegraphy. Morse code is the best-known such code. Telegraphy usually refers to the electrical telegraph, but telegraph systems using the optical telegraph were in use before that. A code consists of a number of code points, each corresponding to a letter of the ...
