The Influence Of Bell

Introduction
Bell’s contribution to both American and the world is enormous, and he deserves a great place in history, greater than the one he currently has.
Reasons
The importance of his contribution is caused by a number of reasons: first of all, the impact of his inventions. We can cite the photophone light-based speech transmitter), the graphophone (sound recorder), the induction balance (used to detect metal pieces inside the human body), and the telephone, which revolutionized telecommunications and still pays a critical role in modern life, 140 years before its invention. All this innovations not only were very useful, but it also were done in a wide range of fields. Precisely this fact gives us another reason to remember him as one
However, the field he was most interested on was helping deaf people to talk, and improving their lifestyle. This passion for the care of the hearing impaired came from his mother and wife’s condition as deaf. This is, in fact, the third reason to give him a great place in our textbooks: much of his work was inspired for his wish of understanding better the physiology of human speech, trying to help people.
ALEXANDER GRAHAM BELL 3
Background and Education
Bell was born in Edinburgh, Scotland. His grandfather had published some books, including The Practical Elocutionist, Stammering and Other Impediments of Speech, and A New
Elucidation of the Principles of Speech and Elocution, and his father had invented the visible speech, a visual system used to teach deaf people to talk. The involvement of his family
His work with him helped Bell to formulate the idea of the telephone.
History of his Most Important Invention: The Telephone
This achievement could not have been possible without the help of his most important assistant, Thomas A. Watson. As said on Scientists: Their Lives and Works: “Watson became
Bell's indispensable assistant, bringing to his experiments the crucial ingredient that had been lacking: technical expertise in electrical engineering”.When talking about the invention of the telephone, it is important to mention Bell’s previous work on the transmission of sound over wires. This led to his experiments on the harmonic telegraph, able to send several messages using only one wire. He also experimented with the transmission of human voice, and in 1874 he developed a membrane that formed the base for the invention of the telephone. However, one of his financial backers, Gardiner Hubbard, who was interested on Bell’s research because of his
