In 1860, in the USA, an Italian immigrant Antonio Meucci showed a device that could transmit sounds by wire. Drawings Antonio acquired Western Union, promising to continue to cooperate with him. In 1876
Meucci learned about the grand invention of the phone by the Scottish scientist Alexander Bell. Since Bell was not well versed in electricity, he took the mechanic Thomas Watson as his partner. The invention itself turned out randomly. During the next experiment, the partner did not have time to fix a small accident, began to swear,and Bell heard his indignant speech at some distance from Watson.
Thus the first telephone was invented. After this event, the phone has undergone many metamorphoses to the state that we see today.
