This enabled him to perceive the possibility of transmitting more than one message along the same wire at one time. Bell's idea was not new, others before him had envisaged a multiple telegraph.
Bell offered his own solution, the "Harmonic Telegraph". This was based on the principal that musical notes could be sent simultaneously down the same wire, if those notes differed in pitch. By the latter part of Bell's experiment had progressed enough for him to inform close family members about the possibility of a multiple telegraph.
Bell's future father in law, attorney Gardiner Green Hubbard saw the opportunity to break the monopoly exerted by the Western Union Telegraph Company.
He gave Bell the financial backing required for him to carry on his work developing the multiple telegraph. However Bell failed to mention that he and his accomplice, another brilliant young electrician Thomas Watson, were developing an idea which occurred to him during the summer.
This idea was to create a device that could transmit the human voice electrically. Bell and Watson continued to work on the harmonic telegraph at the insistence of Hubbard and a few other financial backers.
Joseph Henry was the respected director of the Smithsonian Institution. He listened closely to Bell's ideas and offered words of encouragement. Both Bell and Watson were spurred on by Henry's opinions and continued their work with even greater enthusiasm and determination.
By June they realised their goal of creating a device that could transmit speech electrically would soon be realised. Their experiments had proven different tones would vary the strength of an electric current in a wire. Now all they had to do was build a device with a suitable membrane capable of turning those tones into varying electronic currents and a receiver to reproduce the variations and turn them back into audible format at the other end.
In early June, Bell discovered that while working on his harmonic telegraph, he could hear a sound over the wire. It was the sound of a twanging clock spring. It was on March 10th that Bell was to finally realise the success and communications potential of his new device. The possibilities of being able to talk down an electrical wire far outweighed those of a modified telegraph system, which was essentially based on just dots and dashes.
According to Bell's notebook entry for that date, he describes his most successful experiment using his new piece of equipment, the telephone. Bell spoke to his assistant Watson, who was in the next room, through the instrument and said "Mr Watson, come here, I want to speak to you.
His family were leading authorities in elocution and speech correction. He was groomed and educated to follow a career in the same specialty. By the age of just 29 in he had invented and patented the telephone. Improvements were made on the device including the addition of a microphone, invented by Thomas Edison , which eliminated the need to shout into the telephone to be heard.
Throughout his life, Bell continued his family's work with the deaf, establishing the American Association to Promote Teaching of Speech to the Deaf in Eight years later, Bell assumed the presidency of a small, little-known U. Bell is also one of the founders of Science magazine.
Shortly after his death, the entire telephone system was shut down for one minute in tribute to his genius. We strive for accuracy and fairness.
