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].

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 ...
Part of his duties in 1844 and 1845 were to assist Joseph Henry, Samuel F. B. Morse, [1] and Alfred Vail [2] with the installation of the first Morse telegraph. When the Morse Telegraph Company was formed, Brown left the post office and for the next seven years he continued to work for Samuel Morse as battery tender.
A single needle telegraph (1903) A needle telegraph is an electrical telegraph that uses indicating needles moved electromagnetically as its means of displaying messages.
