According to one researcher, in a February 1838 letter to his father, Judge Stephen Vail, Alfred wrote, "Professor Morse has invented a new plan of an alphabet, and has thrown aside the Dictionaries." [5] In an 1845 book Vail wrote describing Morse's telegraph, he also attributed the code to Morse. [10] He died in 1859 at the age of 51. [11]
American Morse Code — also known as Railroad Morse—is the latter-day name for the original version of the Morse Code developed in the mid-1840s, by Samuel Morse and Alfred Vail for their electric telegraph.
Chart of the Morse code 26 letters and 10 numerals [1]. This Morse key was originally used by Gotthard railway, later by a shortwave radio amateur [2]. 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.
Samuel Finley Breese Morse (April 27, 1791 – April 2, 1872) was an American inventor and painter. After establishing his reputation as a portrait painter, Morse, in his middle age, contributed to the invention of a single-wire telegraph system based on European telegraphs.
It is the site of the first public demonstration of the Morse electromagnetic telegraph on January 11, 1838. Although Morse and Alfred Vail had conducted most of the research and development in the ironworks facilities, they chose the factory house for demonstration. Without the repeater, the range of the telegraph was limited to two miles (3 ...
Telegraph Sounder. A telegraph sounder is an antique electromechanical device used as a receiver on electrical telegraph lines during the 19th century. It was invented by Alfred Vail after 1850 to replace the previous receiving device, the cumbersome Morse register [1] and was the first practical application of the electromagnet.

A telegraph key, clacker, tapper or morse key is a specialized electrical switch used by a trained operator to transmit text messages in Morse code in a telegraphy system. [1] Keys are used in all forms of electrical telegraph systems, including landline (also called wire) telegraphy and radio (also called wireless) telegraphy .
