Synopsis

While Alexander Graham Bell won the race to patent the telephone, he was only one among many inventors who explored instant voice communication. This fascinating book describes the evolution of the telephone from the invention of the telegraph by Marconi to the modern day cell phones that have become a popular part of our everyday life. It also takes a close up look at - how the telephone works - early inventors and those who continue to enhance the technology - telephone companies, their products, and competition. Teacher's guide available.
