Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Excerpt from Telegraph Engineering: A Manual for Practicing Telegraph Engineers and Engineering Students This book is intended for electrical engineering students and as a reference book for practicing telegraph and telephone engineers and for others engaged in the arts of electrical communication. It presents in a logical manner the subject of modern overland and submarine telegraphy from an engineering viewpoint, its theoretical and practical aspects being correlated. No attempt is made to describe all telegraphic devices and to explain their operation, but rather to consider one or more representative types for the accomplishment of the various desired objects, thus permitting a presentation of the subject matter in proper perspective. The book is the outgrowth of the course in Telegraph Engineering given by the author for a number of years at the Polytechnic Institute of Brooklyn. A knowledge of elementary electricity and magnetism is presupposed. For understanding the mathematical demonstrations a knowledge of algebra will in many cases suffice, but in other cases, appearing toward the latter part of the book, the calculus is a necessary adjunct, the study of which frequently precedes or accompanies the vocational studies of students and progressive telegraph workers. That the use of higher mathematics is important in the thorough pursuit of telegraph and telephone transmission studies is evident from an inspection of the writings of Lord Kelvin, Heaviside, Kennelly, Pupin, Campbell, Malcolm and others.

Book excerpt: Excerpt from The History and Progress of the Electric Telegraph: With Descriptions of Some of the Apparatus The favourable reception with which this work has been met by the public and the kindly expressions of encouragement and approval accorded to it by the press, not in England alone, have determined the publishers to reprint it, with some additions, in this smaller and cheaper form The edition in one volume is divided into two parts: the first containing a history of the rise and progress of the art of telegraphy, with descriptions of most of the apparatus in use at the present day; the second being devoted exclusively to the more scientific part of the subject, dealing particularly with matter having an immediate relation to submarine work. It has now been decided to separate these parts into distinct volumes, it being thought that there are many who, whilst interested in the history and apparatus, may not care for the scientific part; whilst others, and especially those connected with telegraphic engineering, may find only the information collected in the second part useful to them.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Manual of Telegraph Construction: The Mechanical Elements of Electric Telegraph Engineering A telegraph structure must fulfil two distinct sets of conditions, the Mechanical and the Electrical. On the subject of the latter there are many special Treatises, on the former this book is the first of its kind. The special Treatises on Telegraphy, with the exception of that of M. Blavier, do not treat of Mechanical principles, these being very justly regarded as distinct from the Electrical conditions, and their full exposition as out of place in a Treatise on the application of Electricity. Although the Mechanical principles and practice are common to other structures than Telegraphs, the particular case of a Telegraph structure requires separate treatment; for some of the materials employed and the functions of the structure are peculiar to Telegraph structures. In no branch are the requirements of the Telegraph Engineer co-extensive with those of the Civil Engineer. Telegraph Engineering has several branches, as mast building, cable laying, &c., not pertaining to Civil Engineering, and Civil Engineering, again, includes many branches, as tunnelling, roads, railways, drainage, water supply, bridge building, &c., of no concern to the Telegraph Engineer. As examples may be instanced carpentry, brickwork, masonry, and earthwork: - the Telegraph Engineer has to join timbers in different ways, to make simple trusses, to build masts, &c.; but he is not concerned with very complex frames, roofs, &c., and is not called upon to execute extensive works in brick or cut stone.

Book excerpt: Excerpt from Journal of the Society of Telegraph Engineers, 1874, Vol. 3: Including Original Communications on Telegraphy and Electrical Science We owe to Gauss and iveber the first great practical realization in abstract science of a system of absolute measurement; but their principles did' not extend rapidly even in the domains of abstract science where their theory was well understood, because the urgent need for its practical application was not felt. When accurate measurement in any definite unit first became prevalent was when it was required by the electric telegraph. The pioneers of science in electric telegraphy, many of whom, happily for us, still work for science and for the electric telegraph, laid down - among various perfectly definite subjects for measurement - a unit of electric resistance - that most primary one of the different things to be measured respecting electricity. I need not remind any of you of the history of electric units of resistance, or of the labours of the Committee of the British Association to bring that system of measurement into harmony with the theoretical definitions of Gauss and Weber. The benefits conferred by introducing a system of definite measurement into the working of the electric telegraph are due not solely - perhaps not even in chief - to the application of Gauss's system, but to the introduction of very accurate and definite standards of resistance and means of reproducing those standards should the originals be lost. The benefit of putting the practical standards into relation with the science of Gauss and Weber has been set forth in the successive reports of the Committee of the British Association on electric measurement, and is well known, I believe, to most of the members of the Society of Telegraph Engineers. But what I wish to say now is that theoretical science has gained great reflected benefit from the introduction of accurate measure ment of resistance into practical telegraphy.
