The invention of the telephone by American inventor Alexander Graham Bell and his first telephone conversation with his assistant Thomas Watson on March 10, 1876 broke new ground in humanity's remote communication efforts.
The phone , which was invented in the USA in 1876 to translate and transmit human voice to electrical signals , has become a center in human life today, transforming into a platform where all kinds of visual, audio and written content are transmitted and received.
The invention of the phone was a revolutionary revolution in remote communication. The invention could translate and transmit human voice into electrical signals, then decode and transmit the signals as sound again. The instant realization of this process meant that the most important goal of humanity's remote communication effort was reached.
The first telephone conversation in history was made in Boston between US inventor Alexander Graham Bell and his assistant Thomas Watson on March 10, 1876.
In a screening that he patented three days ago to publicize his own invention "voice telegraph" device, Bell said to his assistant in the next room with a cable-attached voice transmitter, "Mr. Watson, come here. I want to see you." conveyed his message.
Recently, few technologies have managed to transform human life as radically as the phone.
Bell's invention originally had the same logic of operation as the electrical telegraph previously developed by US inventor Samuel Morse, but it aimed to transmit human voice naturally by encoding different audio frequencies as electrical signals instead of symbolic messages.
The first telephone line
Bell's successful experiment initiated developments that paved the way for the practical use of the phone. In 1877, the first telephone line was established between Boston and Somerville, Massachusetts.
Telephone lines started to spread in the USA in the following years. The lines of long cables carried on wooden poles covered every part of the country.
By the year 1880, there were about 50 thousand telephone devices in the country.
First transcontinental phone call
The first phone call from one end of the American continent to another was held by Bell during the Panama-Pacific International Fair held in California, USA on January 25, 1915. During a meeting on the cable line, where the American continent was laying from one end to the other, Bell called his ex-assistant Watson, who was in the city of San Francisco on the west coast of New York City on the east coast of the continent.
On the same day, US President Woodrow Wilson addressed people from the White House at the fair in San Francisco using the continental line.
The first intercontinental meeting
The first intercontinental phone call was made using radio frequencies, not wired lines. British Postal Office General Manager Evelyn Murray and American Bell Telephone Company Chairman Walter S. Gifford held the first telephone conversation between London and New York on January 7, 1927.
Since laying telephone cables under the ocean was extremely costly, corded phone calls were not used until the first oceanic overseas line between Ireland and Canada's Newfoundland region was established in 1956.
