Telecommunication has undergone unprecedented change in recent times. Two hundred years ago, Sir Francis Ronalds foresaw its development and imagined a world of 'electrical conversations'. His subsequent creations, the most important of which include an early version of the telegraph, have had significant impact on modern living. Little recognized until now, his extraordinary legacy is brought to life through never-before published sources written by people close to the man himself.In this book, details of Sir Francis's inventions — covering areas as diverse as electrical devices, weather forecasting, photography, art, mass production, and even fishing — are interwoven with personal and professional tales of achievement. Fresh light is shone on controversies and precedence in several important discoveries. Using both anecdotal and scientific evidence, it is written for those interested in the pursuit of science in the 19th century and the fascinating developments which have proved essential to the technological revolution of the 21st century.

Telecommunications is a major global industry, and this unique book chronicles the development of this complex technology from the electric telegraph to the Internet in a simple, accessible, and entertaining way. The book opens with the early years of the electric telegraph. The reader will learn how the Morse telegraph evolved into an international network that spanned the globe, starting with the development of international undersea cables, and the heroic attempts to lay a trans-Atlantic cable. The book describes the events that led to the invention of the telephone, and the subsequent disputes over who had really invented it. It takes a look at some of the most important applications that have appeared on the Internet, the mobile revolution, and ends with a discussion of future key developments in the telecommunications industry.

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.

Both first-year electrical engineering students and non-majors taking a survey course in the field will find this book's coverage of circuit analysis, digital systems, electronics, and electromechanics accessible and engaging. Learning about and building things with electronics can be, and should be, enjoyable. This text, therefore, takes an approach that is intended to make learning about electrical engineering fundamentals fun. Fundamentals of Electrical Engineering and Applications deals with the study, design, and application of equipment, devices, and systems that use electricity, electronics, and electromagnetism. Electrical Engineering concentrates on the representation, manipulation, transmission, and reception of information by electrical means.
In the seven decades from its establishment in 1775 to the commercialization of the electric telegraph in 1844, the American postal system spurred a communications revolution no less far-reaching than the subsequent revolutions associated with the telegraph, telephone, and computer. This book tells the story of that revolution and the challenge it posed for American business, politics, and cultural life. During the early republic, the postal system was widely hailed as one of the most important institutions of the day. No other institution had the capacity to transmit such a large volume of information on a regular basis over such an enormous geographical expanse. The stagecoaches and postriders who conveyed the mail were virtually synonymous with speed. In the United States, the unimpeded transmission of information has long been hailed as a positive good. In few other countries has informational mobility been such a cherished ideal. Richard John shows how postal policy can help explain this state of affairs. He discusses its influence on the development of such information-intensive institutions as the national market, the voluntary association, and the mass party. He traces its consequences for ordinary Americans, including women, blacks, and the poor. In a broader sense, he shows how the postal system worked to create a national society out of a loose union of confederated states. This exploration of the role of the postal system in American public life provides a fresh perspective not only on an important but neglected chapter in American history, but also on the origins of some of the most distinctive features of American life today. Table of Contents: Preface Acknowledgments The Postal System as an Agent of Change The Communications Revolution Completing the Network The Imagined Community The Invasion of the Sacred The Wellspring of Democracy The Interdiction of Dissent Conclusion Abbreviations Notes Sources Index Reviews of this book: "[A] splendid new book...that gives the lie to any notion that 'government' and 'administration' were 'absent' in early America." DD--Theda Skocpol, Social Science History "This well-researched and elegantly written book will become a model for historians attempting to link public policy to cultural and political change...[It] will engage not only historians of the early republic, but all scholars interested in the relationship between state and society." DD--John Majewski, Journal of Economic History "The strength of the book is...the author's ability to untangle the thousands of social, political, economic, and cultural threads of the postal fabric and to rearrange them into a clear and compelling social history." DD--Roy Alden Atwood, Journal of American History "Richard R. John provides an insightful cultural history of the often-overlooked American postal system, concentrating on its preeminent status for long-distance communication between its birth in 1775 and the commercialization of the electric telegraph in 1844...John effectively draws upon government documents, newspapers, travelogues, and contemporary social and political histories to argue that the postal system causes and mirrors dramatic changes in American public life during this period...John focuses his study on the communication revolution of the past, yet his meticulous analysis of the complex motives forming the postal institution and its policies relate to such current controversies as those that surround the transmission of information in cyberspace. These contemporary disputes highlight the power of the government in shaping the communication of the people. John privileges the postal institution as the reigning communication system, yet he links it with the developing ideology of the nation, and the scope of his study ensures its value--in the disciplines of communication studies, literature, history, and political science, among others--as a history of the past and present." DD--Sarah R. Marino, Canadian Review of American Studies "Spreading the News exemplifies the kind of sophisticated and nuanced research that US postal history has long needed. Richard R. John breaks from the internalist, antiquarian tradition characteristic of so many post office histories to place the postal system at the centre of American national development." DD--Richard B. Kielbowicz, Business History "[John] presents a thoroughly researched and well-written book...[which will give] insight into the history of the post office and its impact on American life." DD--Library Journal "It is surely true that in Richard John the post has had the good fortune to have found its proper historian, one capable of appreciating the complex design and social importance of the means a people use to distribute information. He has also accomplished the impressive feat of gathering together the pieces of a postal history present elsewhere as so many tiny fragments. John has drawn into a coherent design the stories of postal patronage, the decisions about postal privacy, the incidents along post roads used by others as illustrative anecdotes. John's work has inspired in him a deep appreciation for the accomplishments of the post." DD--Ann Fabian, The Yale Review "John's book explains how the letters and newspapers sent through the post were really the glue that held the early 13 states together and that embraced additional states as the nation expanded westward...It is a splendid attempt to show the importance of mail service in the years before the telegraph or the telephone made at least brief news transmission possible. The postal system of the 19th century really was a factor, perhaps the major factor, in making the United States one nation." DD--Richard B. Graham, Linn's Stamp News "This book traces the central role of the postal system in [its] communications revolution and its contribution to American public life. The author shows how the postal system influenced the establishment of a national society out of a loose union of confederated states. Richard John throws light onto a chapter in American history that is often neglected but sets up the origins of some of the most distinctive features of American life today...The book is a comprehensive study on an important American institution during a critical epoch in its history." DD--Monika Plum, Prometheus [UK] "John has produced an original, well-documented, and thoughtful study that offers alternative and enticing interpretations of Jacksonian policies and public institutions."
