Available in PDF, EPUB and Kindle. Book excerpt: The life-long inventor, Lee de Forest invented the three-element vacuum tube used between 1906 and 1916 as a detector, amplifier, and oscillator of radio waves. Beginning in 1918 he began to develop a light valve, a device for writing and reading sound using light patterns. While he received many patents for his process, he was initially ignored by the film industry. In order to promote and demonstrate his process he made several hundred sound short films, he rented space for their showing; he sold the tickets and did the publicity to gain audiences for his invention. Lee de Forest officially brought sound to film in 1919. Lee De Forest: King of Radio, Television, and Film is about both invention and early film making; de Forest as the scientist and producer, director, and writer of the content. This book tells the story of de Forest’s contribution in changing the history of film through the incorporation of sound. The text includes primary source historical material, U.S. patents and richly-illustrated photos of Lee de Forest’s experiments. Readers will greatly benefit from an understanding of the transition from silent to audio motion pictures, the impact this had on the scientific community and the popular culture, as well as the economics of the entertainment industry.

Available in PDF, EPUB and Kindle. Book excerpt: "This book is not so much an analysis of de Forest's contribution to technology as it is a chronicle of his spiritual quest. Lee de Forest was an important inventor, and this biography attempts to explain what moved him to become one. It tries to show how - in a universe from which deity had seemingly disappeared - de Forest's devotion to invention was part of his search for a new light. The book is not a study in the history of technology but in the history of the religion of technology." "In 1906, de Forest created the "Audion," the three-electrode vacuum tube, which became the foundation of the electronics industry for half a century. He was a pioneer in radio and talking pictures, and he worked on projects ranging from television to solar energy. Holder of more than three hundred patents, he was one of the most prolific inventors in American history." "But he was more than that. Lee de Forest had an immense curiosity that extended beyond science and engineering to politics, literature, and religion. His active and far-ranging mind became a register for many social and intellectual events during his long life: from Populism to McCarthyism, and from Darwinism to agnosticism. But while his interests were diverse, his vision was not. For him invention was not merely a vocation but a worldview. He represented a technological progressivism that advocated reform, but reform stemming less from social engineering than from real engineering. Although he favored certain improvements in law and education, he did not think that these would be the basis of social transformation. Instead, he believed that inventions - ranging from radios to war planes - would reform the human condition and that the future was more in the hands of inventors than statesmen. The millenium would be a technical innovation, with himself as one of its principal inventors." "As a young man, de Forest came to spurn conventional notions of an immortal soul; but he never ceased to seek ways to overcome death - not merely the physical death of the body but also the spiritual death of living without purpose. The fame of his inventions would, he hoped, keep him forever alive in the memory of posterity. Moreover, the good that his inventions did for humanity - his contribution to progress - would give meaning to his existence. For Lee de Forest, then, invention was a substitute for religion. By helping to build the future, he sought to become an indelible part of it."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc. All Rights Reserved

Book excerpt: 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 excerpt: Empire of the Air tells the story of three American visionaries—Lee de Forest, Edwin Howard Armstrong, and David Sarnoff—whose imagination and dreams turned a hobbyist's toy into radio, launching the modern communications age. Tom Lewis weaves the story of these men and their achievements into a richly detailed and moving narrative that spans the first half of the twentieth century, a time when the American romance with science and technology was at its peak. Empire of the Air is a tale of pioneers on the frontier of a new technology, of American entrepreneurial spirit, and of the tragic collision between inventor and corporation.

Available in PDF, EPUB and Kindle. Book excerpt: From AM radio to color television, broadcasting raised enormous practical and policy problems in the United States, especially in relation to the federal government's role in licensing and regulation. How did technological change, corporate interest, and political pressures bring about the world that station owners work within today (and that tuned-in consumers make profitable)? In Radio and Television Regulation, Hugh R. Slotten examines the choices that confronted federal agencies—first the Department of Commerce, then the Federal Radio Commission in 1927, and seven years later the Federal Communications Commission—and shows the impact of their decisions on developing technologies. Slotten analyzes the policy debates that emerged when the public implications of AM and FM radio and black-and-white and color television first became apparent. His discussion of the early years of radio examines powerful personalities—including navy secretary Josephus Daniels and commerce secretary Herbert Hoover—who maneuvered for government control of "the wireless." He then considers fierce competition among companies such as Westinghouse, GE, and RCA, which quickly grasped the commercial promise of radio and later of television and struggled for technological edge and market advantage. Analyzing the complex interplay of the factors forming public policy for radio and television broadcasting, and taking into account the ideological traditions that framed these controversies, Slotten sheds light on the rise of the regulatory state. In an epilogue he discusses his findings in terms of contemporary debates over high-resolution TV.

It explores his career in the decorative arts by examining cultural context, material culture, biography, and patronage. Lockwood de Forest (1850-1932) is best known as an artistic decorator with a flair for designs based on the arts and crafts of the Middle East and India. He began his career in partnership with Louis Comfort Tiffany. By 1883, de Forest had his own business and successfully introduced the East Indian craft revival to the United States. His interior designs and furnishings were embraced by some of the wealthiest families of the Gilded Age. His family home at 7 East Tenth Street in New York City served as a designer showcase and was compared to Arab Hall, a pinnacle of exotic design that was part of Frederic, Lord Leighton's home and studio in Holland Park, London. Complemented by sixty color plates and 132 black-and-white illustrations." --Publisher description.

Available in PDF, EPUB and Kindle. Book excerpt: In this media history of the Caribbean, Alejandra Bronfman traces how technology, culture, and politics developed in a region that was "wired" earlier and more widely than many other parts of the Americas. Haiti, Cuba, and Jamaica acquired radio and broadcasting in the early stages of the global expansion of telecommunications technologies. Imperial histories helped forge these material connections through which the United States, Great Britain, and the islands created a virtual laboratory for experiments in audiopolitics and listening practices. As radio became an established medium worldwide, it burgeoned in the Caribbean because the region was a hub for intense foreign and domestic commercial and military activities. Attending to everyday life, infrastructure, and sounded histories during the waxing of an American empire and the waning of British influence in the Caribbean, Bronfman does not allow the notion of empire to stand solely for domination. By the time of the Cold War, broadcasting had become a ubiquitous phenomenon that rendered sound and voice central to political mobilization in the Caribbean nations throwing off what remained of their imperial tethers.

Available in PDF, EPUB and Kindle. Book excerpt: As the telecommunication and information field expands and becomes more varied, so do publications about these technologies and industries. This book is a first attempt to provide a general guide to that wealth of English-language publications -- both books and periodicals -- on all aspects of telecommunication. It is a comprehensive, evaluative sourcebook for telecommunications research in the United States that brings together a topically-arranged, cross-referenced, and indexed volume in one place. The information provided is only available by consulting a succession of different directories, guides, bibliographies, yearbooks, and other resources. On the one hand, it is a directory that describes in detail the major entities that comprise the American telecommunication research infrastructure including federal and state government offices and agencies, and private, public, and corporate research institutions. On the other hand, it is a bibliography that identifies and assesses the most important and useful reference and critical resources about U.S. telecommunication history, technology, industry and economics, social applications and impacts, plus policy, law and regulations, and role in the global telecommunication marketplace. No existing guide covers all of these aspects in the depth and detail of this volume.
