Book Description
A new look at the early history of wireless communication. By 1897 Guglielmo Marconi had transformed James Clerk Maxwell's theory of electromagnetic waves into a workable wireless telegraphy system, and by 1907 Lee de Forest had invented the Audion, a feedback amplifier and oscillator that opened the way to practical radio transmission. Fifteen years after Marconi's invention, wireless had become an essential means of communication, as well as a hobby for many. This book offers a new perspective on the early days of wireless communication. Drawing on previously untapped archival evidence and recent work in the history and sociology of science and technology, it examines the substance and context of both experimental and theoretical aspects of engineering and scientific practices in the first years of this technology. It offers new insights into the relationship between Marconi and his scientific advisor, the physicist John Ambrose Fleming (inventor of the vacuum tube). It includes the full story of the infamous 1903 incident in which Marconi's opponent Nevil Maskelyne interfered with Fleming's public demonstration of Marconi's syntonic (tuning) system at the Royal Institution by sending derogatory messages from his own transmitter. The analysis of the Maskelyne affair highlights the struggle between Marconi and his opponents, the efficacy of early syntonic devices, Fleming's role as a public witness to Marconi's private experiments, and the nature of Marconi's "shows." It also provides a rare case study of how the credibility of an engineer can be created, consumed, and suddenly destroyed. The book concludes with a discussion of de Forest's Audion and the shift from wireless telegraphy to radio.

Book Description
Excerpt from Wireless Telegraphy: Its History, Theory and Practice Nearly a decade has now elapsed since the wireless telegraph made its spectacular appearance on the horizon of progressive achievement, and in these passing years it has come to be a factor of the first magnitude in the scheme of social and commercial economics which forms the foundation of our complex mode of living. As an example of occult manifestations by the most subtle of nature's forces it stands vividly at the head of this class of phenomena, and the skilled labor it has called forth, that longer distances might be bridged, greater accuracy assured, swifter working effected, and, above all, the correlation of the invisible and elusive waves which would render selectivity a concrete fact, may in a small measure be determined by a perusal of these pages. Since it frequently happens that didactic treatises fall into the hands of the untaught and the simplest of texts are sometimes found useful by the most highly trained specialist, it was proposed that all the various phases of the subject under consideration should receive due attention and, by connecting them in series, a complete and logical account would necessarily follow and one that would bring the state of the art down to the present time. For this reason a brief historical retrospect takes precedence at the beginning of nearly every chapter, and then, in order to fulfil in sequence the conditions cited above, the theoretical deductions, experimental physics and finally the practical workings are given, and it is believed that by pursuing this course of treatment the book will find a hitherto unoccupied niche in the bibliography relating to wireless telegraphy. In conclusion I wish to acknowledge my indebtedness to my friend, Dr. James E. Ives, for many consequential details herein enumerated, and which should, in virtue of his wide experience in the analysis and synthesis of electric wave action, make these portions invaluable to the student as well as to the advanced worker; and my thanks are also due to my brother, Dr. T. Byard Collins and to my wife, both of whom have greatly assisted in its preparation by reading the proofs and checking up the data.
