Alexander Graham Bell was born in Scotland, but moved first for health reasons to Canada, and then to the United States to continue his work as a professor of vocal physiology - how people talk. He put this interest and a fascination for electricity together and began to experiment with transmitting voices over an electric wire. The narrative tells of his struggle to discover the principle which would make the telephone possible and, with the aid of accurate illustrations, how the early telephone worked. The reader will learn how Bell was challenged many times and how his invention revolutionised the field of communications almost immediately.
