what is telephone ? who invented it ?
Answers
Answer:
In 1871, Bell started working on the harmonic telegraph — a device that allowed multiple messages to be transmitted over a wire at the same time. While trying to perfect this technology, which was backed by a group of investors, Bell became preoccupied with finding a way to transmit human voice over wires.
By 1875, Bell, with the help of his partner Thomas Watson, had come up with a simple receiver that could turn electricity into sound.
Other scientists, including Antonio Meucci and Elisha Gray, were working on similar technologies, and there’s some debate over who should be credited with the invention of the telephone. It’s said that Bell raced to the patent office to be the first to secure the rights to the discovery.
On March 7, 1876, Bell was granted his telephone patent. A few days later, he made the first-ever telephone call to Watson, allegedly uttering the now-famous phrase, “Mr. Watson, come here. I want you.”
By 1877, the Bell Telephone Company, which today is known as AT&T, was created. In 1915, Bell made the first transcontinental phone call to Watson from New York to San Francisco.
