The Telephone

"Mr. Watson, come here. I want to see you."

The Inventor, Alexander Graham Bell

This ingenius man created the telephone in 1876. He was originally from Scotland and moved to Boston. Surprisingly, he was just 29 when he invented the telephone. Later he married Mabel Hubbard. He died at the age of 75 in the year 1922.

How It Works

Bell achieved this accomplishment by having a needle glued to a cork, which was pointing at a glass of sulphuric acid. His voice caused the needle to vibrate. This needle was wired to a battery. The strength of the vibration converted the sound waves into an electric signal. A wire moved the signal to a reciever. The first words, "Mr. Watson, come here. I want to see you," were spoken when Bell spilled some of the acid on his pants. Mr. Watson rushed in when we had heard it. The first telephone call had been made!

Evolution Of Phones

Impact On Society

Before the telephone, people only sent important messages because they had to be delivered either by mail or messenger. The telephone allowed people to send messages easily and efficiently. Bell's invention evolved into the cell phones we all rely on today.
