This book chronicles the invention, development and eventual exploitation of the electronics on which we have come to depend for our work, our democracy and our lives. It shows how we went from absolutely nothing to the abundance of electronic items we regard as normal today. Often one thing led to another in an apparently unrelated way. For example, wartime radio to microwave ovens and moonshots to worldwide live TV. There is a long trail of successes, some failures and many unsung heroes who received little credit because someone else was better at publicity. Where these individuals can be identified, their stories are recounted here.
