It received its historical designation from the Government of Canada on June 1, Mabel's exact age when she became deaf would later play a part in the debate on the effectiveness of manual versus oral education for deaf children , as children who are older at the onset of deafness retain greater vocalization skills and are thus more successful in oral education programs.

Some of the debate centred on whether Mabel had to relearn oral speech from scratch, or whether she never lost it.

It was invented in Brantford at Tutela Heights in the summer of Others transmitted a sound or a click or a buzz but our boys [Bell and Watson] were the first to transmit speech one could understand.

Archived from the original on October 15, Retrieved December 29, He founded the Aerial Experiment Association in The first telephone had two parts: a transmitter and a receiver.

The transmitter comprised three parts—a drumlike device a cylinder with a covered end , a needle, and a battery. The covered end of the drumlike device was attached to the needle.

The needle was connected by wire to the battery, and the battery was connected by wire to a receiver. When Bell spoke into the open end of the drumlike device, his voice made the paper and needle vibrate.

The vibrations were then converted into an electric current which traveled along the wire to the receiver. At age 11 he entered the Royal High School at Edinburgh , but he did not enjoy the compulsory curriculum, and he left school at age 15 without graduating.

In the family moved to London. Alexander passed the entrance examinations for University College London in June and matriculated there in the autumn.

Mabel had become deaf at age five as a result of a near-fatal bout of scarlet fever. Bell began working with her in , when she was 15 years old. Despite a year age difference, they fell in love and were married on July 11, They had four children, Elsie — , Marian — , and two sons who died in infancy.

In Joseph Stearns had invented the duplex, a system that transmitted two messages simultaneously over a single wire. Inventors then sought methods that could send more than four; some, including Bell and his great rival Elisha Gray , developed designs capable of subdividing a telegraph line into 10 or more channels.

These so-called harmonic telegraphs used reeds or tuning forks that responded to specific acoustic frequencies.

They worked well in the laboratory but proved unreliable in service. A group of investors led by Gardiner Hubbard wanted to establish a federally chartered telegraph company to compete with Western Union by contracting with the Post Office to send low-cost telegrams.

Bell, however, was more interested in transmitting the human voice. Finally, he and Hubbard worked out an agreement that Bell would devote most of his time to the harmonic telegraph but would continue developing his telephone concept.

From harmonic telegraphs transmitting musical tones, it was a short conceptual step for both Bell and Gray to transmit the human voice.

Bell filed a patent describing his method of transmitting sounds on February 14, , just hours before Gray filed a caveat a statement of concept on a similar method.

On March 7, , the Patent Office awarded Bell what is said to be one of the most valuable patents in history.

It is most likely that both Bell and Gray independently devised their telephone designs as an outgrowth of their work on harmonic telegraphy. However, the question of priority of invention between the two has been controversial from the very beginning.

Despite having the patent, Bell did not have a fully functioning instrument. He first produced intelligible speech on March 10, , when he summoned his laboratory assistant, Thomas A.
