Toronto, Ontario: Natural Science of Canada. 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.

Watson—come here—I want to see you. In August of that year, he was on the receiving end of the first one-way long-distance call, transmitted from Brantford to nearby Paris, Ontario, over a telegraph wire.

When he began experimenting with electrical signals, the telegraph had been an established means of communication for some 30 years.

Although a highly successful system, the telegraph was basically limited to receiving and sending one message at a time. Bell's extensive knowledge of the nature of sound enabled him to imagine 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, no one had been able to perfect one. Watson, a skilled electrician, to keep Bell on track.

By October , Bell's research had progressed to the extent that he could inform his future father-in-law about the possibility of a multiple telegraph.

Hubbard, who had long resented the absolute control then exerted by the Western Union Telegraph Company, instantly saw the potential for breaking such a monopoly and gave Bell the financial backing he needed.

Bell proceeded with his work on the multiple telegraph, but he did not tell Hubbard that he and Watson were also developing a device that would transmit speech electrically.

While Watson worked on the harmonic telegraph at the insistent urging of Hubbard and other backers, Bell secretly met in March with Joseph Henry , the respected director of the Smithsonian Institution, who listened to Bell's ideas for a telephone and offered encouraging words.

Spurred on by Henry's positive opinion, Bell and Watson continued their work. By June , the goal of creating a device that would transmit speech electrically was about to be realized.

They had proven that different tones would vary the strength of an electric current in a wire. Pada tahun , Kansas City undertaker Almon B.
