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.

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.

Electric Fire Alarm System

On 28 April 1852 the first municipal electric fire alarm system using call boxes with automatic signaling to indicate the location of a fire was placed into operation in Boston. Invented by William Channing and Moses Farmer, this system was highly successful in reducing property loss and deaths due to fire and was subsequently adopted throughout the United States and in Canada.

In January 1838, Samuel F. B. Morse and Alfred Vail first demonstrated publicly crucial elements of their telegraph system, using instruments that Vail had constructed during the previous months. Electrical pulses, transmitted through two miles of wire, caused an electromagnet to ink dots and dashes (grouped to represent letters and words) on a strip of paper. Commercialization began in 1844 when funding became available. A ministerial student, a professor of fine arts, and a prominent industrialist...

The discoveries of electricity in the latter half of the 18th Century, and its close connection with magnetism, were the products of earlier experiments, which in turn led to the invention of the electric telegraph. Telegraphy had connected the interior of the United States, and it also connected Europe together. However, connecting the Americas and Europe proved to be a challenge. Due to the electric current that ran through the cable lines, insulation and waterproofing was necessary.
