Inventor: Alexander Graham Bell
Invention created in: 1876
Background: Bell was a teacher at a school for the deaf. He tried to invent a machine to send messages over an electronic wire. This eventually led to the idea of a telephone. Later, with his assistant, he created a device to produce and receive sound waves using electrical signals.
First phone call: On 10 March 1876, Bell made the first clear and complete phone call to his assistant, saying, “Mr Watson–come here–I want to see you.”
Other information: Bell never had a telephone in his study, where he wanted to be alone with his thoughts and work.
