Alexander Graham Bell
1847-1922
"The inventor looks upon the world and is not contented with things as they are. He wants to improve whatever he sees, he wants to benefit the world; he is haunted by an idea. The spirit of invention possesses him, seeking materialization.“ Alexander Graham Bell

At last they decided to try a new kind of transmitter (микрофон). The new transmitter was set in Bell's bedroom on the first floor. Watson was sitting in the laboratory on the ground floor . He put his ear to the receiver (трубка) and was waiting. Suddenly he heard Bell's voice. And not the voice only but the words too: "Mr. Watson, come here. I want to see you! " Watson ran upstairs and shouted, "I heard you! " It was on the 10th of March, 1876. The telephone was invented.

*** Years after Bell’s invention, there is a story told of a woman whom he met at a party. When she was introduced to the great inventor she expressed pleasure in meeting him and then she said smilingly, “But often I wish you had never been born.” Bell smiled and said, “I sympathize. I never use that beast myself.” The most extraordinary thing is that Bell hated the telephone, he hardly ever used it.
