Answer: Alexander Graham Bell.
Explanation: He was the man that created the telephone in 1876. He invented it because he believed it was his important invention, so he decided to invent it. It was made for communication, and it allowed it for sound to transmit through a sound beam.
More facts: One of his assistants, Thomas A. Watson tired to reactivate a telegraph, and Bell had an idea and solved the problem. How? He sent a human voice over a wire.
Without the telephone: If we didn't have the telephone, we couldn't communicate with our friends! We'll had to go to their location or let them come where we came.
