Power Struggles


Book Description

Laying the foundation for Thomas Edison, the first electric generators were built in the 1830s, the earliest commercial lighting systems before 1860, and the first commercial application of generator-powered light in the early 1860s. This book examines some of these early applications of electricity.




Sir Francis Ronalds: Father Of The Electric Telegraph


Book Description

Telecommunication has undergone unprecedented change in recent times. Two hundred years ago, Sir Francis Ronalds foresaw its development and imagined a world of 'electrical conversations'. His subsequent creations, the most important of which include an early version of the telegraph, have had significant impact on modern living. Little recognized until now, his extraordinary legacy is brought to life through never-before published sources written by people close to the man himself.In this book, details of Sir Francis's inventions — covering areas as diverse as electrical devices, weather forecasting, photography, art, mass production, and even fishing — are interwoven with personal and professional tales of achievement. Fresh light is shone on controversies and precedence in several important discoveries. Using both anecdotal and scientific evidence, it is written for those interested in the pursuit of science in the 19th century and the fascinating developments which have proved essential to the technological revolution of the 21st century.




Edison and the Electric Chair


Book Description

Thomas Edison stunned America in 1879 by unveiling a world-changing invention--the light bulb--and then launching the electrification of America's cities. A decade later, despite having been an avowed opponent of the death penalty, Edison threw his laboratory resources and reputation behind the creation of a very different sort of device--the electric chair. Deftly exploring this startling chapter in American history, Edison & the Electric Chair delivers both a vivid portrait of a nation on the cusp of modernity and a provocative new examination of Edison himself. Edison championed the electric chair for reasons that remain controversial to this day. Was Edison genuinely concerned about the suffering of the condemned? Was he waging a campaign to smear his rival George Westinghouse's alternating current and boost his own system? Or was he warning the public of real dangers posed by the high-voltage alternating wires that looped above hundreds of America's streets? Plumbing the fascinating history of electricity, Mark Essig explores America's love of technology and its fascination with violent death, capturing an era when the public was mesmerized and terrified by an invisible force that produced blazing light, powered streetcars, carried telephone conversations--and killed.
