In 1892, the telephone lines in New York and Chicago were opened . Bell, the inventor of the telephone, was the first to audition: "Hello, Chicago", and this historic sound was recorded.
Today, people living in different places need to communicate directly. They do not need to send letters or rush to the other party's location in person. They can do it through the phone. Who invented the telephone, a communication tool, and when? The inventor of the telephone was Bell. He was originally from Scotland and was born in 1847. He immigrated to the United States when he was 24 years old and became an American citizen soon after. In 1873 he was a professor of speech physiology at Boston University. Once, he attempted to send several messages simultaneously through a telegraph wire. His idea was supported by his wife Mabel Hubbard and his father-in-law. Mabel is deaf and was a former student of Bell's. Her father was relatively wealthy and generously provided necessary financial support for his son-in-law's scientific experiments.
Many of Bell's friends wanted him to study telegraphy. But the inventor disagreed. The only thing on his mind was to complete the job of transmitting human voices. He first experimented with a "harmonic telegraph" - a collection of two harp-like sets of electrified reeds connected on a wire. Each reed has a counterpart of the same frequency at that end of the wire. Bell hung two "harps" from magnetic film. This membrane is a device that mimics the human ear.
One day, Bell's assistant Thomas Watson was playing with the clamped reeds, and Bell heard the sound of plucked strings from the neighboring room from the wire. He noted the facts, which led to further experiments. During the experiment, Bell encountered many difficulties. But he was an open-minded and studious person, so when he asked for advice from others, he received guidance and help from some famous scientists, including famous physicists Helmholtz, Joseph Henry, Edison, etc.
On March 10, 1876, Bell shouted through the walkie-talkie: "Mr. Watson, please come here! I have something to ask you!"
Watson's assistant in the laboratory When he heard the call, he jumped out of the laboratory like crazy and ran to the dormitory where Bell shouted. He shouted all the way: "I heard Bell calling me! I heard Bell calling me!"...
In this way, mankind has the first telephone call, opening a new page of communication history. In 1877, the first news dispatch sent by telephone was sent to the Boston "World", marking the adoption of the telephone by the public. In 1878, the Bell Telephone Company was officially established.
