". . . rarely have inventor and invention been better served than in this book." – New York Times Book Review Here, Edwin Grosvenor, American Heritage's publisher and Bell's great-grandson, tells the dramatic story of the race to invent the telephone and how Bell's patent for it would become the most valuable ever issued. He also writes of Bell's other extraordinary inventions: the first transmission of sound over light waves, metal detector, first practical phonograph, and early airplanes, including the first to fly in Canada. And he examines Bell's humanitarian efforts, including support for women's suffrage, civil rights, and speeches about what he warned would be a "greenhouse effect" of pollution causing global warming.

Alexander Graham Bell’s invention of the telephone in 1876 stands as one of the great touchstones of American technological achievement. Bringing a new perspective to this history, Invented by Law examines the legal battles that raged over Bell’s telephone patent, likely the most consequential patent right ever granted. To a surprising extent, Christopher Beauchamp shows, the telephone was as much a creation of American law as of scientific innovation. Beauchamp reconstructs the world of nineteenth-century patent law, replete with inventors, capitalists, and charlatans, where rival claimants and political maneuvering loomed large in the contests that erupted over new technologies. He challenges the popular myth of Bell as the telephone’s sole inventor, exposing that story’s origins in the arguments advanced by Bell’s lawyers. More than anyone else, it was the courts that anointed Bell father of the telephone, granting him a patent monopoly that decisively shaped the American telecommunications industry for a century to come. Beauchamp investigates the sources of Bell’s legal primacy in the United States, and looks across the Atlantic, to Britain, to consider how another legal system handled the same technology in very different ways. Exploring complex questions of ownership and legal power raised by the invention of important new technologies, Invented by Law recovers a forgotten history with wide relevance for today’s patent crisis.

On March 7, 1876, the U.S. Patent Office issued to a young inventor named Alexander Graham Bell what is arguably the most valuable patent ever: entitled "improvements in telegraphy," in truth it secured for Bell the basic principles involved in a telephone. On the same day that Bell filed his patent application, a caveat (a preliminary patent document) was filed by Elisha Gray. This coincidence sparked the first of many debates over whether Bell was the true inventor of the telephone. In the early 1860s Johann Phillipp Reis developed a version of the instrument, but his claims against Bell were hampered by the bungling of his lawyers in demonstrating his instrument in court. This work is a first look at the many men who developed the telephone and an examination of their claims against Bell's patent. A lay description of the phone is also provided, as well as a history of the development of the telephone system.

Alexander Graham Bell invented the telephone during the years of the Industrial Age in Europe and America. It was the day and age for new innovations and new devices that exploded in the field of manufacturing. While many of those instruments were suited for large companies and the wealthy, why not invent devices that everyone could use? This is the story of Alexander Graham Bell, of his telephone and of all the other inventions that sprung from his fruitful mind. Although he worked with the deaf, he never lived in a world of silence, and neither did his hearing-impaired family and friends. Inside you'll read about Budding Inventor A Lovely Wife: A Loving Life Mixing Business with Pleasure And much more!Alexander Graham Bell was a precious young man, and it didn't dismay him that many others, who were older and more experienced than he, were scrambling to build the world's first telephone. There was a stampede to the patent office toward the latter half of the 19th Century. Patent attorneys were shown anything from rough pencil drawings to scribbled out explanations of how these devices were sure to work. Many, many of the applicants presented verbal ideas. Others, though, designed carefully engineered diagrams and prototypes. Only Alexander Graham Bell and his assistant, James Watson, had demonstrated it in front of influential scientists and notable statesmen at a University.

The popular image of Alexander Graham Bell is that of an elderly American patriarch, memorable only for his paunch, his Santa Claus beard, and the invention of the telephone. In this magisterial reassessment based on thorough new research, acclaimed biographer Charlotte Gray reveals Bell’s wide-ranging passion for invention and delves into the private life that supported his genius. The child of a speech therapist and a deaf mother, and possessed of superbly acute hearing, Bell developed an early interest in sound. His understanding of how sound waves might relate to electrical waves enabled him to invent the “talking telegraph” be- fore his rivals, even as he undertook a tempestuous courtship of the woman who would become his wife and mainstay. In an intensely competitive age, Bell seemed to shun fame and fortune. Yet many of his innovations—electric heating, using light to transmit sound, electronic mail, composting toilets, the artificial lung—were far ahead of their time. His pioneering ideas about sound, flight, genetics, and even the engineering of complex structures such as stadium roofs still resonate today. This is an essential portrait of an American giant whose innovations revolutionized the modern world.
