The telephone was invented by the Italian inventor Antonio Meucci. He built it to connect his office with his bedroom so he could talk to his wife, who was immobilized in bed due to illness. The device could transmit acoustic signals at a distance by means of electrical signals. Meucci had no money to patent the invention, so his discovery was never recognized.
