Book Description
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 Description
Here is an often cited panoramic history of the telegraph which discusses the principal telegraph firms and the key persons within them. Throughout his work, Reid stresses the business and economic aspects of marketing this remarkable scientific invention. The importance of The Telegraph in America as a classic reference in the field is under-scored by the fact that the author was active in telegraphy throughout the period he discusses. He thus had a personal knowledge of persons and events under examination.

Book Description
Samuel F.B. Morse's invention of the telegraph marked a new era in communication. For the first time, people were able to communicate quickly from great distances. The genesis of Morse's invention is covered in detail, starting in 1832, along with the establishment of the first transcontinental telegraph line in the United States and the dramatic effect the device had on the Civil War. The Morse telegraph that served the world for over 100 years is explained in clear terms. Also examined are recent advances in telegraph technology and its continued impact on communication.

Book Description
Excerpt from American Telegraph Practice: A Complete Technical Course in Modern, Telegraphy, Including Simultaneous Telegraphy and Telephony In this work the aim has been to give a detailed exposition of the various systems of telegraphy in use in America at the present time, together with a complete description of modern methods of operation, and an extensive compilation of the formulae used in practical telegraphy. One occasionally hears it remarked that since the practical introduction of the quadruplex about thirty years ago there have been no important developments in telegraphy, but those who have been engaged in the work of improving telegraph apparatus and operating methods are well aware that even since the last American book dealing with this subject was written several years ago, material progress has been made in several directions. The fact that to-day eighty telegrams per hour are handled over a single Morse outlet where ten years ago half that number in the same time was considered good performance, and that during the same period the time of transmission of a telegram between cities remotely separated has been reduced at least one-half, cannot but be regarded as convincing evidence that vast improvement has taken place. One factor that has contributed largely to the improvement in the service is the increasing technical knowledge of the men engaged in operating the plant; and this, in spite of the fact that the production of technical telegraph literature has not kept pace with the actual development of the art. In the present work the author has incorporated all of the elemental essentials of the general subject as well as all of the new departures which have made for betterment, and an attempt has been made to treat the various divisions of the subject in terms that should make it possible for the student, by due exercise of diligence, to qualify himself for the most advanced positions in the service. Incidentally, it might here be stated that it is no longer possible for the telegrapher to make much headway in the service without an understanding of arithmetic and elementary algebra, and, while usually mathematical formulae are regarded as being incomprehensible, by those who have not had the advantages of high school education, the author believes that as herein employed and worked out, all of the required mathematics may be mastered without difficulty.

Book Description
When John White returned to Roanoke Island in 1590, the English colony he had left there three years earlier was abandoned. The only traces of the 117 colonists were letters carved on trees. The search to discover the fate of the missing Roanoke Island settlers has gone on for over four hundred years. The mystery remains unsolved today. In The Mysterious Disappearance of Roanoke Colony in American History, an exciting addition to the "In American History" series, Zachary Kent examines the lost colony at Roanoke. Through fast-paced story telling and quotes from historic men and women, Kent helps readers understand the background and history of the Roanoke experiment. The author also discusses modern attempts to solve the disappearance. Book jacket.

Book Description
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.
