This audiobook tells the story of how Alexander Graham Bell came up with the telephone, and how his invention changed the way people communicate.

The biography of the teacher of the deaf who, through his knowledge of music, human speech, and hearing, invented the telephone. Bell was a pioneer in many fields that aided communication over distances. He worked tirelessly to help the deaf communicate with others (even Helen Keller came to him for help).
