History Of Telegraphy written by K. G. Beauchamp and has been published by IET this book supported file pdf, txt, epub, kindle and other format this book has been release on 2001 with Technology & Engineering categories.
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.

First published in 1921, this book was originally intended to supplement the knowledge of electrical engineers with limited experience of wireless telegraphy. Turner examines various branches of the technology's development, focusing especially on the thermionic method of wireless, and compares telegraphy to telephony. This book will be of value to anyone with an interest in the history of science, telegraphy in particular.

Excerpt from American Telegraphy and Encyclopedia of the Telegraph: Systems, Apparatus, Operation Somewhat less than twenty-five years ago the simple Morse system of telegraphy was the only one in general use in America. One or two printing telegraph systems were in operation, and attempts were being made to utilize, satisfactorily, chemical automatic telegraph systems. At that time, although the duplex system of telegraphy was in limited use, it had not been perfected, and in some quarters it was looked upon as a "scientific toy," "very beautiful in its way but quite useless in a practical point of view." Since then the duplex and quadruplex systems, and the Wheatstone automatic telegraph system, have been extensively introduced into the commercial telegraph service of this country. Since then, also, multiplex, phonoplex, burglar alarm, police signal and other analogous systems of telegraphy have been invented and placed in successful operation. Many important improvements in printing telegraphy, submarine telegraphy, fire alarm telegraphy, etc., have, in recent years, also been introduced, and in numerous other ways the art of electrical telegraphy has been advanced. While a number of the systems and improvements referred to have, at different times, and at more or less length, been described in electrical books and periodicals, the writer is not aware that even a majority of them has been fully described in any one book, and thus a knowledge of them placed within easy reach of the ordinary student of telegraphy. Believing that such a book would be of value, the attempt has been made, in the present work, to supply a comprehensive account of the systems of telegraphy now in use in America, and as such an account naturally includes sources of electromotive force employed, line construction, line and apparatus testing, etc., those subjects have also been dwelt upon at some length. As far as possible each subject has been treated from a practical standpoint, and the book, as a whole, has been written in a manner intended to be clear to novices in electrical matters, more especially those who are directly engaged in the practical working of electrical systems of telegraphy. To that end, where it has seemed essential to a proper understanding of a subject, full, and, it is hoped, accurate, explanations of laws and facts of electricity and magnetism involved in the operation of systems and methods described, have been given.
