Thomas A. Edison – författare

The third volume of this widely acclaimed series reveals the breath-taking intensity, intellectual acumen, and vast self-confidence of twenty-nine-year-old Thomas Edison. In the depths of the 1870s depression, he moved his independent research and development laboratory from industrial Newark to pastoral Menlo Park, some fifteen miles to the south on the main line of the railroad from New York to Philadelphia. There, equipped with resources for experimental development that were extraordinary for their time, Edison and a few close associates began twenty months of research that expanded their well-established accomplishments in telegraphy into pioneering work on the telephone. Edison's ideas and techniques from telegraph message recording and the telephone next led to his invention of the phonograph, the first patent for which was filed in December 1877. This invention ultimately gave Edison a world-wide reputation--and the nickname "the wizard of Menlo Park."

The fifth volume of The Papers of Thomas A. Edison covers Edison's invention and development of the first commercial incandescent electric light and power system. In the process he turned his famed Menlo Park laboratory into the first true research and development facility. This also enabled him to develop a new telephone for the British market in the midst of his herculean efforts on electric lighting. In the face of daunting technical challenges and skepticism from leading scientists and engineers, Edison and his team of experimenters and machinists found the solution to the decades-old problem of creating a practical incandescent lamp. By focusing on the characteristics of the entire system Edison reconceptualized the requirements of a successful lamp design. While rivals worked primarily on lamps, Edison developed other parts of a complete system as well. This approach was most notable in his revolutionary work on generator technology, one of the highlights of this volume. Successful exhibitions of the system in December 1879 drew crowds to Menlo Park to witness the softly glowing lamps.These spectacles gratified his financial backers but Edison realized the importance of following experimental demonstrations with the hard work of commercial development. He needed to make each component work effectively in daily use and to improve the designs so that they were easy to use and inexpensive to manufacture. To create a daytime market for electricity he also developed electric motors for a variety of uses, including electric railways, for which he built a small demonstration line at Menlo Park. To accomplish all this Edison greatly enlarged his staff to as many as sixty experimenters, machinists, carpenters, and office workers. He began manufacturing lamps at a factory in Menlo Park. At the end of 1880, Edison was ready to move his system into commercial production and made plans to produce other components in New York. He also invited New York officials to a demonstration in order to win their approval for running underground lines in lower Manhattan where he planned to put his first commercial central station.In March 1881, he moved to the Edison Electric Light Company's headquarters on Fifth Avenue and began the hard work of introducing the new electric light and power technology.

This newest volume in the acclaimed 'Papers of Thomas A. Edison' covers one year in the life of America's greatest inventor--1878. That year Edison, whom a New York newspaper in the spring first called "the Wizard of Menlo Park," developed the phonograph, one of his most famous inventions; made a breakthrough in the development of telephone transmitters, which made the instrument commercially viable; and announced the advent of domestic electric lighting, with only a few weeks' worth of tinkering necessary to complete its design (the announcement sent gas-company stocks plummeting; the research and development went on for four years). These inventions brought Edison financial support for his work and attention from the public. In January investors in the Edison Speaking Phonograph Company agreed to fund development work on the phonograph. The invention made Edison internationally famous and in May he traveled to Washington, D.C., to show the phonograph at the National Academy of Sciences, to Congress, and to President Rutherford B. Hayes at the White House.That same month Western Union agreed to pay Edison an annual salary of $6,000 for his telephone inventions, although other support from the company declined following the death of its president, William Orton. The stress of unceasing public attention, including a trans-Atlantic dispute over the question of who invented the microphone, led an exhausted Edison to travel west during the summer to witness a solar eclipse but also to seek rest. His six-week trip took him to San Francisco and the Yosemite region of California. Edison began working on electric lighting after his return and in October the Edison Electric Light Company was formed to support his research.

With his move from Menlo Park, New Jersey, to New York City at the end of March 1881, Edison shifted his focus from research and development to the commercialization of his electric lighting system. This volume of The Papers of Thomas A. Edison chronicles Edison's central role in the enormous effort to manufacture, market, and install electric lighting systems in the United States and abroad. Standard studies of this period emphasize the inauguration of the commercial electric utility industry at the Pearl Street central station. Edison and his associates, however, audaciously operated on a global scale, not just focusing on the major cities of North America and Europe but reaching simultaneously from Appleton, Wisconsin, to Australia, through the Indian subcontinent and East Asia, to Central and South America.

Edison: "A mine of material...Scrupulously edited...No one could ask for more...A choplicking feast for future Edison biographers-well into the next century, and perhaps beyond."- Washington Post "What is most extraordinary about the collection isn't necessarily what it reveals about Edison's inventions...It's the insight into the process."- Associated Press "Those interested in America's technological culture can eagerly look forward to the appearance of each volume of the Edison Papers."- Technology and Culture "His lucidity comes through everywhere...His writing and drawing come together as a single, vigorous thought process."- New York Times "A triumph of the bookmaker's art, with splendidly arranged illustrations, essential background information, and cautionary reminders of the common sources on which Edison's imagination drew."- New York Review of Books "In the pages of this volume Edison the man, his work, and his times come alive...A delight to browse through or to read carefully."- Science "Beyond its status as the resource for Edison studies, providing a near inexhaustible supply of scholarly fodder, this series...will surely become a model for such projects in the future...The sheer diversity of material offered here refreshingly transcends any exclusive restriction to Edisonia."- British Journal for the History of Science

Seeking to replicate the success of his New York electric central station throughout the United States and in Europe and Latin America, Thomas A. Edison vowed to become a "business man for a year." This bold decision began a remarkable transition period for America's greatest inventive thinker. The seventh volume of Edison's papers chronicles the profound changes in his professional and personal life, including the unexpected death of his wife. It concludes with Edison returning to the laboratory to develop new communications technology.

Two decades after the American Civil War, no name was more closely associated with the nation's inventive and entrepreneurial spirit than that of Thomas Edison. The restless changes of those years were reflected in the life of America's foremost inventor. Having cemented his reputation with his electric lighting system, Edison had decided to withdraw partially from that field. At the start of 1885, newly widowed at mid-life with three young children, he launched into a series of personal and professional migrations, setting in motion chains of events that would influence his work and fundamentally reshape his life. Edison's inventive activities took off in new directions, flowing between practical projects (such as wireless and high-capacity telegraph systems) and futuristic ones (exploring forms of electromagnetic energy and the convertibility of one to another). Inside of two years, he would travel widely, marry the daughter of a prominent industrialist and religious educator, leave New York City for a grand home in a sylvan suburb, and construct a winter laboratory and second home in Florida.Edison's family and interior life are remarkably visible at this moment; his papers include the only known diary in which he recorded personal thoughts and events. By 1887, the familiar rhythms of his life began to reassert themselves in his new settings; the family faded from view as he planned, built, and occupied a New Jersey laboratory complex befitting his status. The eighth volume of the series, New Beginnings includes 358 documents (chosen from among thousands) that are the most revealing and representative of Edison's work, life, and place in American culture in these years. Illustrated with hundreds of Edison's drawings, these documents are further illuminated by meticulous research on a wide range of sources, including the most recently digitized newspapers and journals of the day.

This richly illustrated volume explores Edison's inventive and personal pursuits from 1888 to 1889, documenting his responses to technological, organizational, and economic challenges.Thomas A. Edison was received at the 1889 Paris Exposition Universelle—the World's Fair—as a conquering hero. Extravagantly fêted and besieged by well-wishers, he was seen, like Gustave Eiffel's iron tower, as a triumphal symbol of republicanism and material progress. The visit was a high-water mark of his international fame.Out of the limelight, Edison worked as hard as ever. On top of his work as an inventor, entrepreneur, and manufacturer, he created a new role as a director of research. At his peerless laboratory in Orange, New Jersey, he directed assistants working in parallel on multiple projects. These included the "perfected" phonograph; a major but little-recognized effort to make musical recordings for sale; the start of work on motion pictures; and improvements in the recovery of low-grade iron ore. He also pursued a public "War of the Currents" against electrical rival George Westinghouse. Keenly attuned to manufacturing as a way to support the laboratory financially and control his most iconic products, Edison created a new cluster of factories. He kept his manufacturing rights to the phonograph while selling the underlying patents to an outside investor in a deal he would regret. When market pressures led to the consolidation of Edison lighting interests, he sold his factories to the new Edison General Electric Company. These changes disrupted his longtime personal and professional relations even as he planned an iron-mining project that would take him to the New Jersey wilderness for long periods.The ninth volume of the series, Competing Interests explores Edison's inventive and personal pursuits from 1888 to 1889, documenting his responses to technological, organizational, and economic challenges. The book includes 331 documents and hundreds of Edison's drawings, which are all revealing and representative of his life and work in these years. Essays and notes based on meticulous research in a wide range of sources, many only recently available, provide a rich context for the documents.

A comprehensive chronicle of Edison's industrial, technological, and electrical pursuits from 1890 to 1892.Thomas A. Edison started the 1890s as one of the most famous people in the Western world, with his name celebrated in small-town newspapers and imperial courts. However, the changing technological and corporate environments of this decade raised obstacles that Edison could only partially overcome while reorienting his career away from his signature electrical technologies.The tenth volume of the widely acclaimed series The Papers of Thomas A. Edison chronicles the end of the "Battle of the Currents," the contest over the development of US electric utility infrastructure. Edison struggled to adapt his direct-current system to overcome the advantages of the Westinghouse Electric alternating-current system and to outpace Thomson-Houston Electric's development of motors for industry and electric traction. The forced merger with Thomson-Houston that created General Electric in 1892 ended Edison's dozen years of leadership in the electrical business. Edison remained prolific in other fields documented in this volume—sound recording, motion pictures, and batteries. But all these projects were overshadowed by his efforts to revitalize uncompetitive eastern iron mines by concentrating low-grade iron ores. Edison opened a massive ore-concentrating works in Ogdensburg, New Jersey, in 1890. The operation, improvement, and expansion of that plant consumed much of his energy and wealth for the rest of the decade.
