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.

The invention of the telephone is a subject of great controversy, central is which is the patent issued to Alexander Graham Bell on March 7, 1876. Many problems and questions surround this patent, not the least of which was its collision in the Patent Office with a strangely similar invention by archrival Elisha Gray. A flood of lawsuits followed the patent's issue; at one point the government attempted to annul Bell's patent and launched an investigation into how it was granted. From court testimony, contemporary accounts, government documents, and the participants' correspondence, a fascinating story emerges. More than just a tale of rivalry between two inventors, it is the story of how a small group of men made Bell's patent the cornerstone for an emerging telephone monopoly. This book recounts the little-known story in full, relying on original documents (most never before published) to preserve the flavor of the debate and provide an authentic account. Among the several appendices is the "lost copy" of Bell's original patent, the document that precipitated the charge of fraud against the Bell Telephone Company.

Alexander Graham Bell invented the telephone or did he? Inventor Antonio Santi Giuseppe Meucci was also working on a telephone at the same time. Watch Meucci and Bell race to be first to the invention finish line.

". . . 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.

Nine remarkable men produced inventions that changed the world. The printing press, the telephone, powered flight, recording and others have made the modern world what it is. But who were the men who had these ideas and made reality of them? As David Angus shows, they were very different quiet, boisterous, confident, withdrawn but all had a moment of vision allied to single-minded determination to battle through numerous prototypes and produced something that really worked. It is a fascinating account for younger listeners.
