Also, at this time the first "wireless" transatlantic telegrams were being sent and it was obvious that a wireless-radio communications system would become the next telecommunications technical revolution. Ed Nally went on to become VP of American Marconi and later the first president of RCA (in 1919.)In 1925, Clarence Mackay formed Mackay Radio & Telegraph Company.Photo above: The back of a 1912 Postal Telegraph Telegram with a map showing the cables that extend two-thirds of the way around the earth. The company was to operate a radiogram service that provided world-wide communications using company owned and operated stations.Though the discovery of electricity and the beginnings of radio can be traced back to Thales of Miletus (static electricity charge via amber,) the first deliberately sent electromagnetic "signal" was the result of experiments performed in 1868 by a Virginia dentist named Malon Loomis.His device consisted of identical length wires held aloft by kites separated by a distance of 18 miles.
By 1891, Nikola Tesla was beginning to demonstrate wireless and in 1892 gave a demonstration of wireless transmission and reception at the Franklin Institute.
The ITT-Mackay name in radio was actively used for decades, sometimes as Mackay Marine ITT and also Mackay Thales.
Nowadays, Mackay Communications Company is doing business out of North Carolina. Mackay's wealth - acquired in Virginia City, Nevada - he would not have had the financial wealth and power to form the vast telecommunications company that eventually allowed his son, Clarence Mackay, to form Mackay Radio & Telegraph Company. Even Jay Gould said that he couldn't beat John Mackay because ",..he (Mackay) needed more money he would just go to Nevada and dig up some more." The historic telecommunications and radio connection to Nevada is certainly real and Mackay and his telecommunications companies there at the beginning.
With connections using timed switching, each system would alternately connect galvanometers and ground connections.
Loomis was able to see a "cause and effect" that he attributed to "atmospheric static electricity." Loomis appealed to Congress for ,000 to develop his system but the post-Civil War politicians were not interested in wireless communications and saw "no value" to Loomis' experiments.
