17 Mar A History of the Telephone
This article will give you a brief overview of the history of the telephone. You will be able to understand the history of the telephone and how it became a vital part of modern life. But you will have to know that Bell was not the first person to try to come up with the concept. In fact, there were over a dozen inventors working on this very idea before Bell got started. The first telephone was not invented until Bell’s research was completed in 1876.
The first telephones were manual and connected to a local exchange. These exchanges were connected by trunks. These trunks were plugged into each other to create long-distance calls. At this time, about 100,000 telephone operators were employed in the United States. In 1892, the telephone network was expanded from one town to another and Chicago was connected to New York. In 1894, the telephone reached the Pacific Ocean and two years later, New York was connected to San Francisco. It was during this time that Alexander Graham Bell made his first phone call, and it would be over three million by the end of the century.

Alexander Graham Bell moved back to Boston to continue his research on the telephone. He used a liquid transmitter to transmit sounds. A needle in water vibrated because of the diaphragm vibrations. This varying resistance varied the electrical resistance within the circuit. The transmission of speech was successful just five days later.
