Alexander Graham Bell
By: Kayla

Alexander Graham Bell was a famous American inventor. His mom and wife couldn't hear, so he was interested in ways he could help the deaf. He taught the deaf and was a speech therapist. He invented a piece of equipment that detected the vibrations in someone's voice. It was called the phonautograph. It could draw the vibrations and it helped his students see what the human voice looked like. The phonautograph made Bell wonder if he could show voice sounds electrically. He and his assistant tested a receiver and transmitter that allowed them to speak to each other. This is what we know now as the telephone.
