First Operational Use Of Wireless Telegraphy
Society: IEEEMain Category: ElectricEra: 1900-1909DateCreated: 1899-1902Telkom MuseumCapetownCountry: South AfricaWebsite:,_1899-1902

The first use of wireless telegraphy in the field occurred during the Anglo-Boer War (1899-1902). The British Army experimented with Marconi's system and the British Navy successfully used it for communication among naval vessels in Delagoa Bay, prompting further development of Marconi's wireless telegraph system for practical uses. The Anglo-Boer War of 1899-1902 will be remembered as the last of the gentleman's wars, the war that marked the end of the Victorian era.

The first transmission of intelligible speech over electrical wires took place on 10 March 1876. Inventor Alexander Graham Bell called out to his assistant Thomas Watson, “Mr. Watson, come here! I want to see you.” This transmission took place in their attic laboratory located in a near here at 5 Exeter Place. A pioneer in the field of telecommunications, Alexander Graham Bell was born in 1847 in Edinburgh, Scotland. He moved to Ontario, and then to the United States, settling in Boston, before beginning his career as an inventor.

On 10 August 1876, Alexander Graham Bell demonstrated on this site that the human voice could be transmitted electrically over distance. While family members spoke into a transmitter in Brantford, 13 km away, Bell was able to hear them at a receiver located in Paris. This test convinced Bell that his invention could be used for communication between towns and could compete successfully with the telegraph.

NHK began the world's first direct broadcast satellite service in May, 1984. This was the culmination of eighteen years of research that included the development of an inexpensive low-noise receiver and investigations of rain attenuation in the 12 GHz band. RRL, NASDA, TSCJ, Toshiba Corporation, General Electric Company, and NASA participated with NHK to make satellite broadcasting to the home a practical reality.

The United States Electric Illuminating Company of Charleston started up South Carolina's first central station for incandescent lighting in October 1882 -- only one month after Thomas Edison opened his famous Pearl Street plant in New York City. In the following years, the company's parent firm was a major force in the growing electrical industry.

First 500 MeV Proton Beam from the TRIUMF Cyclotron

At 3:30 pm on 15 December 1974, the first 500 MeV proton beam was extracted from the TRIUMF cyclotron. Since then, TRIUMF has used proton beams from its cyclotron (and secondary beams of pions, muons, neutrons and radioactive ions produced in its experimental halls) to conduct pioneering studies that have advanced nuclear physics, particle physics, molecular and materials science, and nuclear medicine.

First 735 kV AC Transmission System

Hydro-Quebec's 735,000 volt electric power transmission system was the first in the world to be designed, built and operated at an alternating-current voltage above 700 kV. This development extended the limits of long-distance transmission of electrical energy. On 29 November 1965 the first 735 kV line was inaugurated. Power was transmitted from the Manicouagan-Outardes hydro-electric generating complex to Montreal, a distance of 600 km.

Experimental Breeder Reactor I

At this facility on 20 December 1951 electricity was first generated from the heat produced by a sustained nuclear reaction providing steam to a turbine generator. This event inaugurated the nuclear power industry in the United States. On 4 June 1953 EBR-I provided the first proof of "breeding" capability, producing one atom of nuclear fuel for each atom burned, and later produced electricity using a plutonium core reactor.

Electronic Technology for Space Rocket Launches

The demonstrated success in space flight is the result of electronic technology developed at Cape Canaveral, the J. F. Kennedy Space Center, and other sites. A wide variety of advances in radar tracking, data telemetry, instrumentation, space-to-ground communications, on-board guidance, and real-time computation were employed to support the U.S. space program. These and other electronic developments provided infrastructure necessary for the successful landing of men on the moon in July 1969 and their safe return to earth.

A key milestone in development of the quartz electronic wristwatch in Switzerland was the creation in 1962 of the Centre Electronique Horloger of Neuchâtel. The Centre produced the first prototypes incorporating dedicated integrated circuits that set new timekeeping performance records at the International Chronometric Competition held at this observatory in 1967. Since then quartz watches, with hundreds of millions of units produced, became an extremely successful electronic system.
