Download or read book Makers of the Telegraph written by Kenneth B. Lifshitz and published by McFarland. This book was released on 2017-02-13 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: The single-wire telegraph revolutionized long distance communication but it was not the brainchild of one inventor, Samuel Morse. His colleagues and employees--specifically Ezra Cornell and Joseph Henry--made crucial contributions. Examining the careers of the three men and the key events, this book presents Morse as primarily a businessman and consolidator of ideas who, frequently in conflict with his associates, sought to present the telegraph as a uniform system under his sole imprimatur. The battle between Morse and Cornell over the invention of the magnetic relay was central to the drama. What emerges is a complex portrait of three ambitious and brilliant innovators and the age in which they lived.

Download or read book The Codebreakers written by David Kahn and published by Simon and Schuster. This book was released on 1996-12-05 with total page 1307 pages. Available in PDF, EPUB and Kindle. Book excerpt: The magnificent, unrivaled history of codes and ciphers -- how they're made, how they're broken, and the many and fascinating roles they've played since the dawn of civilization in war, business, diplomacy, and espionage -- updated with a new chapter on computer cryptography and the Ultra secret. Man has created codes to keep secrets and has broken codes to learn those secrets since the time of the Pharaohs. For 4,000 years, fierce battles have been waged between codemakers and codebreakers, and the story of these battles is civilization's secret history, the hidden account of how wars were won and lost, diplomatic intrigues foiled, business secrets stolen, governments ruined, computers hacked. From the XYZ Affair to the Dreyfus Affair, from the Gallic War to the Persian Gulf, from Druidic runes and the kaballah to outer space, from the Zimmermann telegram to Enigma to the Manhattan Project, codebreaking has shaped the course of human events to an extent beyond any easy reckoning. Once a government monopoly, cryptology today touches everybody. It secures the Internet, keeps e-mail private, maintains the integrity of cash machine transactions, and scrambles TV signals on unpaid-for channels. David Kahn's The Codebreakers takes the measure of what codes and codebreaking have meant in human history in a single comprehensive account, astonishing in its scope and enthralling in its execution. Hailed upon first publication as a book likely to become the definitive work of its kind, The Codebreakers has more than lived up to that prediction: it remains unsurpassed. With a brilliant new chapter that makes use of previously classified documents to bring the book thoroughly up to date, and to explore the myriad ways computer codes and their hackers are changing all of our lives, The Codebreakers is the skeleton key to a thousand thrilling true stories of intrigue, mystery, and adventure. It is a masterpiece of the historian's art.
