Краткий пересказ The Man and His Work

Two world wars helped to develop the chemical industry. The 20th century gave us the automobile, the airplane, the helicopter, the cinema, the computer and the nuclear reactor.

People believe that inventions occur as the need arises. From this point of view, someone else might have invented the telephone. As it happened, it was Alexander Graham Bell.

He was born in Scotland and spent his youth in England. His parents moved in scientific circles, where experiments were being carried out on the human voice. That was the reason why Bell became interested in the subject. Later he began experimenting with a multiple telegraph that could send more than one message at a time.

After graduating from the University of London, Bell was a teacher of the deaf. Later he moved to America and invented a little machine, that he could use in teaching the deaf. This little machine called the phonautograph, gave him a key to the invention of the telephone. Bell took on an assistant, Thomas A. Watson, who knew about electricity a lot more than he did. They were working together, when Bell's idea for the telephone came to him.

The first model of his invention was shown in 1876
