ALEXANDER GRAHAM BELL

Alexander's Experiments

In 1871, Alexander moved to Boston. Why? Because he began to work on a device that allow several messages set to different frequencies in the telegraph transmission. From 1873 until 1874, Alexander put tremendous efforts in a long days and night trying to get the harmonic telegraph. 

 

In the between years, he developed an idea of transmitting the human voice over wires. 

The changes of the Bell’s new idea have disappointing Alexander's supporters and Thomas Watson. Thomas Watson is a talented electrician and he was assigned to refocus Bell on the harmonic telegraph again. 

Later, Watson enchanted to the idea of voice transmission they have a great partnership.

In the following years, Bell experimented on how to detect metal in wounds and with a vacuum-jacket respirator that led to the development of the iron lung.

In 1874 and the following years, Alexander Graham Bell and Thomas Watson put together the harmonic telegraph and the voice transmitting device. The values of voice transmission experiments attract the investors and the idea has filed a patent.

Finally on March 10, 1876, they were successful. The famous and meaningful sentence, "Mr. Watson, come here. I want you!" is the explanation of Bell is able to hear a noise over the wire and so do Watson. They received the first telephone call.

The Achievements of Alexander Graham Bell

Alexander Graham Bell is capable to boost the careers of other scientist by using the wealth from the telephone achievement. Bell founded the National Geographic Society, the premier American scientific journal. 

While continuing experiments in science, Bell is helping the deaf, and he convincing their integration into society. Alexander was successfully founded his own corporation named Alexander Graham Bell Association for the Deaf.

Another success of Alexander Graham Bell is, his telephone was promoted in a series of public demonstration in 1876, at the Centennial Exhibition in Philadelphia.

Later on July 9, 1877, The Bell Telephone Company was established.
