The Telephone

Alexander Graham Bell first successfully spoke to Thomas Watson over his telephone device in 1876. But in order to invent the telephone, Bell had to study the work of scientists who came before him. And to this day, engineers continue to build upon this history of invention, resulting in the sleek, powerful smartphones in use today. From Charles Bourseul's early idea to send sound waves through wires, to the cell towers of today, this book explores the invention and evolution of the telephone.
