While in the U. In , he opened the School of Vocal Physiology and Mechanics of Speech in Boston, where deaf people were taught to speak.
While teaching, Bell met Mabel Hubbard, a deaf student. The couple married on July 11, They went on to have four children, including two sons who died as infants.
In , Bell started working on the harmonic telegraph — a device that allowed multiple messages to be transmitted over a wire at the same time.
While trying to perfect this technology, which was backed by a group of investors, Bell became preoccupied with finding a way to transmit human voice over wires.
By , Bell, with the help of his partner Thomas Watson, had come up with a simple receiver that could turn electricity into sound.
On March 7, , Bell was granted his telephone patent. Watson, come here. I want you. In , the U. In addition to the telephone, Bell worked on hundreds of projects throughout his career and received patents in various fields.
Some of his other notable inventions were:. In , Bell was awarded the French Volta Prize, and with the money, he founded a facility devoted to scientific discovery, the Volta Laboratory in Washington, D.
Bell invented numerous techniques to help teach speech to the deaf and even worked with well-known author and activist Helen Keller.
He also helped launch Science magazine , and from to served as president of the National Geographic Society.
In , Bell was given the controversial title of honorary president at the Second International Congress of Eugenics. It talks!
Bell, who was then a full-time teacher, had not planned to exhibit at the fair because of his heavy teaching schedule and preparation for his student's examinations.

During his tour of the continent, the Belgian government offered him the greatest financial incentives to establish his European subsidiary's headquarters in their country.
BTMC eventually came under complete ownership by Western Electric, and also established other divisions as national companies across Continental Europe and Russia.

In only a few years, Western Union's president would acknowledge that it was a serious business error, one that nearly led to his company later almost being swallowed up by the newly emerging telecommunications giant into which Bell Telephone would shortly evolve.
Western Union was saved from demise only by the U. Government's anti-monopoly interventions. The project was the first of its kind to create a nationwide long-distance network with a commercially viable cost-structure.
Starting from New York City, its long-distance telephone network reached Chicago, Illinois, in ,  with its multitudes of local exchanges continuing to stretch further and further yearly, eventually creating a continent-wide telephone system.
John Elbridge Hudson joined Bell Telephone as counsel in and served as president from to In , there was a large strike across the US against the company's long hours and low pay by its workers.
The memorial was planned to be completed by [ when? Allward designed the monument to symbolize the telephone's ability to overcome distances.
At each end of the memorial there are two female figures mounted on granite pedestals representing Humanity , one sending and the other receiving a message.
The Bell Telephone Memorial 's grandeur has been described as the finest example of Allward's early work, propelling the sculptor to fame.
The memorial itself has been used as a central fixture for many civic events and remains an important part of Brantford's history, helping the city of Brantford to style itself as 'The Telephone City'.
The Bell Memorial Association also purchased the Bell family's former farmhouse, Melville House, and its orchard at Tutela Heights, opening it as a museum to the family and to the invention of the telephone.
In , it was declared a historic landmark, and is now known as the Bell Homestead National Historic Site. From Wikipedia, the free encyclopedia.
