How did Alexander Graham Bell invent the telephone? Bell's extensive knowledge of the nature of sound and his understanding of music enabled him to conjecture the possibility of transmitting multiple messages over the same wire at the same time. Although the idea of a multiple telegraph had been in existence for some time, Bell offered his own musical or harmonic approach as a possible practical solution. His "harmonic telegraph" was based on the principle that several notes could be sent simultaneously along the same wire if the notes or signals differed in pitch.

Help us to communicate with friends/family members easily.We like his inventions because they are very useful.

He is very determine to complete his invention and he perservere.

Bell's inventions spanned a wide range of interests and included the audiometer to detect minor hearing problems, a device to locate icebergs, investigations on how to separate salt from seawater, and work on finding alternative fuels. He also worked extensively in medical research and invented techniques for teaching speech to the deaf.
