Guglielmo Marconi is sometimes called the father of the radio, because he was the first person to send radio waves over a long distance. But in order to achieve this feat, Marconi had to study the successes and shortcomings of earlier inventors’ experiments. To this day, engineers continue to build upon this history of invention, resulting in the radio technology of today. From Heinrich Hertz to Nikola Tesla and more, this book explores the invention and evolution of the radio.
