Beauchamp (1923-99, retired from the U. of Lancaster, UK) devotes the first half of the book to terrestrial telegraphy, from the beginnings of communication with mechanical signaling to the electrical system using Morse code, including a large chapter on the laying of submarine cables across the English Channel and the Atlantic Ocean. The second half, on aerial telegraphy, discusses its beginnings with Marconi and its use on board ships and aircraft in both world wars. Dozens of maps show routes of telegraph cable and figures depict old telegraph equipment. Annotation copyrighted by Book News Inc., Portland, OR.

Download The Telegraph in America, 1832–1920 Book in PDF, ePub and Kindle
A complete history of how the telegraph revolutionized technological practice and life in America. Telegraphy in the nineteenth century approximated the internet in our own day. Historian and electrical engineer David Hochfelder offers readers a comprehensive history of this groundbreaking technology, which employs breaks in an electrical current to send code along miles of wire. The Telegraph in America, 1832–1920 examines the correlation between technological innovation and social change and shows how this transformative relationship helps us to understand and perhaps define modernity. The telegraph revolutionized the spread of information—speeding personal messages, news of public events, and details of stock fluctuations. During the Civil War, telegraphed intelligence and high-level directives gave the Union war effort a critical advantage. Afterward, the telegraph helped build and break fortunes and, along with the railroad, altered the way Americans thought about time and space. With this book, Hochfelder supplies us with an introduction to the early stirrings of the information age.

In the second half of the nineteenth century, British firms and engineers built, laid, and ran a vast global network of submarine telegraph cables. For the first time, cities around the world were put into almost instantaneous contact, with profound effects on commerce, international affairs, and the dissemination of news. Science, too, was strongly affected, as cable telegraphy exposed electrical researchers to important new phenomena while also providing a new and vastly larger market for their expertise. By examining the deep ties that linked the cable industry to work in electrical physics in the nineteenth century - culminating in James Clerk Maxwell's formulation of his theory of the electromagnetic field - Bruce J. Hunt sheds new light both on the history of the Victorian British Empire and on the relationship between science and technology.
