Death and misfortune were often the spark for engineers and technologists to turn scientific discovery into everyday electronic appliances. Alexander Graham Bell was a specialist teacher of the deaf, while it took many deaths from contaminated food before the first cooling machines were constructed. Some of the earliest equipment is little-known today. There is no linear trajectory from the Teletrophone, Tamodine and Phantascope to the telephone, lightbulb and projector, but this book sheds light on their role. It shows how, over a hundred years, a few basic inventions spawned the huge range of electronic devices that have changed the way we live.
