Alexander Graham Bell’s Early Years

Elisha Gray and Alexander Graham Bell, each independently, designed devices that could transmit speech electrically. Mabel had become deaf at age five as a result of a near-fatal bout of scarlet fever.

Bell began working with her inwhen 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 Graydeveloped 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. He filed the patent for his telephone at the U. Patent Office on February 14, —just two hours before a rival, Elisha Gray, filed a declaration of intent to file a patent for a similar device.

Watson, assistant to Alexander Graham Bell, discussing the birth of the telephone, including the first words spoken. 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.
