Published in 1907, this book became a key text for radio engineers and enthusiasts who wanted to understand wireless technology.
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.
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.
This study offers an analysis of the technological and entrepreneurial features of the Victorian telegraph service, together with the companies which ran it until nationalization in 1869. It shows a historical reconstruction mainly based on original and unedited documents belonging to a variety of archives.

"This study also explores the surprising parallels between the telegraphy of the nineteenth century and the work of women in technical fields today. The telegrapher's work, like that of the modern computer programmer, involved translating written language into machine-readable code. And anticipating the Internet by over one hundred years, telegraphers often experienced the gender-neutral aspect of the "cyberspace" they inhabited."--BOOK JACKET.
