Wireless telegraphy is the practice of remote writing (see telegraphy) without the wires normally involved in an electrical telegraph. Wireless telegraphy devices started appearing in the 1860s. Edison, for example, patented one in 1885 for use by trains. The so-called father of wireless telegraphy is considered by many to be Jozef Murgas, for his revolutionary work in the late 1880s. Telegraphy (from the Greek words tele = far and graphein = write) is the long-distance transmission of written messages without physical transport of letters, originally over wire. ...

In St. Louis, Missouri, Nikola Tesla made the first public demonstration of such a system in 1893. Addressing the Franklin Institute in Philadelphia and the National Electric Light Association, he described and demonstrated in detail the principles of wireless telegraphy. The apparatus that he used contained all the elements that were incorporated into radio systems before the development of the vacuum tube.

The later derived system (which used several patents of Tesla's) that achieved widespread use was demonstrated by Guglielmo Marconi in 1896. As far back as Faraday and Hertz in the early 1800s, it was clear to most scientists that wireless communication was possible, and many people worked on developing many devices and improvements. For instance, in 1832, James Bowman Lindsay gave a classroom demonstration of wireless telegraphy to his students. By 1854 he was able to demonstrate transmission across the Firth of Tay from Dundee to Woodhaven (now part of Newport-on-Tay), a distance of two miles. Marconi and Braun shared the 1909 Nobel Prize in physics for "contributions to the development of wireless telegraphy". Guglielmo Marconi Guglielmo Marconi, GCVO (25 April 1874 – 20 July 1937) was an Italian electrical engineer and Nobel laureate, known for the development of a practical wireless telegraphy system commonly known as the radio.

A few decades later, the term radio became more popular. Early radio could not transfer sounds, only Morse code in the tones made by rotary spark gaps. Canadian-American scientist Reginald Aubrey Fessenden was the first to wirelessly transmit a human voice (his own). Read more about History of radio. The ultimate development of wireless telegraphy was telex on radio. The most advanced form (CCITT R.44) automated both routing and encoding of messages over short wave radio. Telex on radio was invented in the 1940s, and was for many years the only reliable way to reach many distant countries (See telegraphy for more information). 1922 Chart of the Morse Code Letters and Numerals Morse code is a method for transmitting information, using standardized sequences of short and long marks or pulses — commonly known as dots and dashes — for the letters, numerals and special characters of a message. ...
