The Invention of the Telephone
water transmitter
Around the same time, Elisha Gray was developing his own telephone using what kind of transmitter?
Boston University
Around this time, Alexander Graham Bell was teaching at what university?
speech overtones
Further experiments on multiple telegraph led to an accidental discovery. When Bell's assistant, Thomas Watson accidentally plucked a reed, and Bell heard the overtones and realized that they were similar to what kind of overtones?
A working transmitter with a membrane capable of varying electronic currents and a receiver that would reproduce these variations in audible frequencies.
Realizing that they were moving closer to developing a device that could transmit speech , Bell and his assistant set about creating what?
a toy
Th president of the company said no, feeling that the new invention was nothing but what?
"Mr. Watson come here I want to see you"

Who did Bell offer to sell his patent to for $100,000?
William Orton
Who was the President of the Western Union?
Thomas Edison and Elisha Gray
William Orton had contracted with what inventors to find a way to send multiple messages on the same line to avoid the cost of constructing new lines?
Antonio Meucci
Another inventor deserves some credit for inventing the telephone. Who was he?
material evidence
Although he sued Bell, he was not able to prove much in the way of what, and his case died with him in 1889?
Elisha Gray
At the same time, who was developing a similar system to Bell's?
It was a theory of a multiple harmonic telegraph that could be used to send a multiple tones on a telegraph line.
Bell first developed a theory of what?
February of 185
Both men submitted patents for their invention when?
one message
By 1884, communication traffic on the 30 year-old system had become very congested and operators were limited to sending how many messages at a time per line?
Thomas Edison
In 1879, the telephone company acquired whose patent for the carbon microphone, which made the telephone practical for long distances, unlike Bell's voice-powered transmitter that required users to shout to be heard even at short distances?
telegraph
The telephone was created as a direct result of trying to improve what machine?
lawsuits
There is still debate over who should receive the credit and Bell had to fight off what by those claiming they had invented the telephone first?
telephone
These closely timed submissions would foreshadow their competition over development of what invention?
English
Through misfortune and his lack of understanding what, Meucci was not able to renew his caveat or apply for a patent before Bell submitted his?
$25 million
Two years later, after the president rejected the telephone, the president told the colleagues he would consider how much money for the patent which was a bargain, but by that time the Belle Telephone Company was no longer interested in selling the patent?
A system that could transmit musical notes and speech.
What kind of system did Bell want to develop?
the science of acoustics
What science did Bell have a keen interest in?
