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: 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.

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.

In the futuristic world of Indigo, reproduction is controlled by the government, guaranteeing that every baby is happy, healthy, and beautiful. But mistakes happen, and a rare few babies are accidentally born biologically, like Magdala Cled.

When he offers to transfer Magdala's consciousness into the body, she cannot refuse the priceless opportunity for a new, beautiful life.

Now Magdala must impersonate Christophine to infiltrate high society, court Claudio's advances, and decide whose side she is truly on--all while maintaining her real body lest it die...and she die with it.

Available in PDF, EPUB and Kindle. Book excerpt: In the forty-year history of Star Trek®, none of the television show's actors are more beloved than DeForest Kelley. His portrayal of Leonard "Bones" McCoy, the southern physician aboard the Starship Enterprise™, brought an unaffected humanity to the groundbreaking space frontier series. Jackson DeForest Kelley came of age in Depression-era Georgia. He was raised on the sawdust trail, a preacher's kid steeped in his father's literal faith and judgment. But De's natural artistic gifts called him to a different way, and a visit to California at seventeen showed a bright new world. Theater and radio defined his early career -- but it was a World War II training film he made while serving in the Army Air Corps that led to his first Paramount Studios contract. After years of struggle, his lean, weathered look became well known in notable westerns and television programs such as You Are There and Bonanza. But his work on several pilots for writer-producer Gene Roddenberry changed his destiny and the course of cultural history. This thoroughly researched actor's life is about hard work and luck, loyalty and love. It is a journey that takes us all...from sawdust to stardust.

Available in PDF, EPUB and Kindle. Book excerpt: Still broadcasting today, the world's first radio station was invented by Charles Herrold in 1909 in San Jose, California. His accomplishment was first documented in a notarized statement written by him and published in the Electro-Importing Company's 1910 catalog: "We have given wireless phone concerts to amateur wireless men throughout the Santa Clara Valley." Being the first to "broadcast" radio entertainment and information to a mass audience puts him at the forefront of modern day mass communication. This biography of Charles Herrold focuses on how he used primitive technology to get on the air. Today it is a 50,000-watt station (KCBS, in San Francisco). The authors describe Herrold's story as one of early triumph and final failure, the story of an "everyman," an individual who was an innovator but never received recognition for his work and, as a result, died penniless. His most important work was done between 1912 and 1917, and following World War I, he received a license and operated station KQW for several years before running out of money. Herrold then worked as a radio time salesman, an audiovisual technician for a high school, and a janitor at a local naval facility, still telling anyone who would listen to him that he was the father of radio. The authors also consider some other early inventors, and the directions that their work took.

Available in PDF, EPUB and Kindle. Book excerpt: From the Preface: Few if any events have had greater impact on the history of film than the coming of the talkies, film historians have paid relatively little attention to how and why the transition from silent to sound cinema came about. It is hoped that the present work will provide the factual groundwork for repairing that neglect. Its emphasis is on the history of American contributions to the evolution of the sound film, but significant foreign achievements have not been overlooked. The book surveys the events that led from the invention of the phonograph in 1877 to that momentous evening in 1927 when an audience at the Warner's Theatre in New York City saw and heard Al Jolson speak from the screen. It also considers the effects of the sound revolution on Hollywood and Hollywood film production during the transitional years 1928-29. The published sources on which this study was based have all been indicated in the notes, and the reader is advised to consult that original material whenever he requires additional technical or factual information.
