Beschreibung

This book was written back when the telephone was a new device.  In The History of the Telephone you will see how much of a fight Bell and his associates had on their hands to prove the telephone could be useful and wasn’t just a parlor trick.  We learn why Bell and his associated companies fought so hard to defend their patents.
