Product Description
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.

5.0 out of 5 stars Where radio came from, February 12, 2002

By	Harvey M. Solomon (Smyrna, GA USA) - See all my reviews

This book is an excellent history of important events associated with the early scientific understanding of electromagnetic radiation and with the technical development of wireless communication. It answers many questions which have been raised concerning the roles of individuals who participated in critical events associated with the transition from electrics to electronics. Activities which occurred over 100 years ago are skillfully recreated based on extensive research involving many unusual references. The book is well written and demonstrates a high level of scholarship. It explains clearly how the rudimentary spark gap transmitter and primitive receiver which Marconi brought to England in 1896 was so effectively transformed that a successful transatlantic transmission of the letter S took place in 1901. The quality of the illustrations, circuit diagrams and figures obtained from laboratory note books and patent applications is excellent. No photographs of Marconi with various social luminaries of the time are included; this only enhances the quality of the book and the judgement of the author.

The author thoroughly documents the technical progression from Edison's monode, to Fleming's diode, to De Forest's triode and characterizes how the development and understanding of these important early hollow-state devices contributed to the ultimate introduction of continuous wave technology.

It has been illegal to communicate with spark gap transmitters since the late 1920's. Today few people know how such devices sound. In honor of the 100th anniversary of Marconi's first transatlantic transmission, VE3BBN was permitted to operate a low-power rotary spark transmitter on the 80 meter amateur band. (...)

3.0 out of 5 stars Covers an important part of radio history, January 27, 2008

By	Randolph Cabell "Old Sparky" (Virginia) - See all my reviews (REAL NAME)

The structure is pretty good, but it gets bogged down in the two areas in which I was most interested. (1) the evolution to tuned LC circuits which are the foundation of all radio and TV today -- the ability to generate specific frequencies rather than the wide-band-noise of a spark. and (2) the importance of the TRIODE which argurebly was the greatest single invention to bring us radio. He does talk about "The Edison Effect" and "The Audion" which I think - but am not sure -- was actually the triode. But all in all, the best short history of radio at that time period that I have come across.
