Codes, Ciphers and Spies by John F. Dooley Pdf

When the United States declared war on Germany in April 1917, it was woefully unprepared to wage a modern war. Whereas their European counterparts already had three years of experience in using code and cipher systems in the war, American cryptologists had to help in the building of a military intelligence unit from scratch. This book relates the personal experiences of one such character, providing a uniquely American perspective on the Great War. It is a story of spies, coded letters, plots to blow up ships and munitions plants, secret inks, arms smuggling, treason, and desperate battlefield messages. Yet it all begins with a college English professor and Chaucer scholar named John Mathews Manly. In 1927, John Manly wrote a series of articles on his service in the Code and Cipher Section (MI-8) of the U.S. Army’s Military Intelligence Division (MID) during World War I. Published here for the first time, enhanced with references and annotations for additional context, these articles form the basis of an exciting exploration of American military intelligence and counter-espionage in 1917-1918. Illustrating the thoughts of prisoners of war, draftees, German spies, and ordinary Americans with secrets to hide, the messages deciphered by Manly provide a fascinating insight into the state of mind of a nation at war.

In the Enemy's House by Howard Blum Pdf

The New York Times bestselling author of Dark Invasion and The Last Goodnight once again illuminates the lives of little-known individuals who played a significant role in America’s history as he chronicles the incredible true story of a critical, recently declassified counterintelligence mission and two remarkable agents whose story has been called "the greatest secret of the Cold War." In 1946, genius linguist and codebreaker Meredith Gardner discovered that the KGB was running an extensive network of strategically placed spies inside the United States, whose goal was to infiltrate American intelligence and steal the nation’s military and atomic secrets. Over the course of the next decade, he and young FBI supervisor Bob Lamphere worked together on Venona, a top-secret mission to uncover the Soviet agents and protect the Holy Grail of Cold War espionage—the atomic bomb. Opposites in nearly every way, Lamphere and Gardner relentlessly followed a trail of clues that helped them identify and take down these Soviet agents one by one, including Julius and Ethel Rosenberg. But at the center of this spy ring, seemingly beyond the American agents’ grasp, was the mysterious master spy who pulled the strings of the KGB’s extensive campaign, dubbed Operation Enormoz by Russian Intelligence headquarters. Lamphere and Gardner began to suspect that a mole buried deep in the American intelligence community was feeding Moscow Center information on Venona. They raced to unmask the traitor and prevent the Soviets from fulfilling Soviet Premier Nikita Khrushchev’s threat: "We shall bury you!" A breathtaking chapter of American history and a page-turning mystery that plays out against the tense, life-and-death gamesmanship of the Cold War, this twisting thriller begins at the end of World War II and leads all the way to the execution of the Rosenbergs—a result that haunted both Gardner and Lamphere to the end of their lives.

Unsolved! by Craig P. Bauer Pdf

"In 1953, a man was found dead from cyanide poisoning near the Philadelphia airport with a picture of a Nazi aircraft in his wallet. Taped to his abdomen was an enciphered message. In 1912, a book dealer named Wilfrid Voynich came into possession of an illuminated cipher manuscript once belonging to Emperor Rudolf II, who was obsessed with alchemy and the occult. Wartime codebreakers tried--and failed--to unlock the book's secrets, and it remains an enigma to this day. In this lively and entertaining book, Craig Bauer examines these and other vexing ciphers yet to be cracked. Some may reveal the identity of a spy or serial killer, provide the location of buried treasure, or expose a secret society--while others may be elaborate hoaxes. Unsolved! begins by explaining the basics of cryptology, and then explores the history behind an array of unsolved ciphers. It looks at ancient ciphers, ciphers created by artists and composers, ciphers left by killers and victims, Cold War ciphers, and many others. Some are infamous, like the ciphers in the Zodiac letters, while others were created purely as intellectual challenges by figures such as Nobel Prize-winning physicist Richard P. Feynman. Bauer lays out the evidence surrounding each cipher, describes the efforts of geniuses and eccentrics--in some cases both--to decipher it, and invites readers to try their hand at puzzles that have stymied so many others. Unsolved! takes readers from the ancient world to the digital age, providing an amazing tour of many of history's greatest unsolved ciphers"--

The Woman Who Smashed Codes by Jason Fagone Pdf

National Bestseller NPR Best Book of the Year “Not all superheroes wear capes, and Elizebeth Smith Friedman should be the subject of a future Wonder Woman movie.” —The New York Times Joining the ranks of Hidden Figures and In the Garden of Beasts, the incredible true story of the greatest codebreaking duo that ever lived, an American woman and her husband who invented the modern science of cryptology together and used it to confront the evils of their time, solving puzzles that unmasked Nazi spies and helped win World War II. In 1916, at the height of World War I, brilliant Shakespeare expert Elizebeth Smith went to work for an eccentric tycoon on his estate outside Chicago. The tycoon had close ties to the U.S. government, and he soon asked Elizebeth to apply her language skills to an exciting new venture: code-breaking. There she met the man who would become her husband, groundbreaking cryptologist William Friedman. Though she and Friedman are in many ways the "Adam and Eve" of the NSA, Elizebeth’s story, incredibly, has never been told. In The Woman Who Smashed Codes, Jason Fagone chronicles the life of this extraordinary woman, who played an integral role in our nation’s history for forty years. After World War I, Smith used her talents to catch gangsters and smugglers during Prohibition, then accepted a covert mission to discover and expose Nazi spy rings that were spreading like wildfire across South America, advancing ever closer to the United States. As World War II raged, Elizebeth fought a highly classified battle of wits against Hitler’s Reich, cracking multiple versions of the Enigma machine used by German spies. Meanwhile, inside an Army vault in Washington, William worked furiously to break Purple, the Japanese version of Enigma—and eventually succeeded, at a terrible cost to his personal life. Fagone unveils America’s code-breaking history through the prism of Smith’s life, bringing into focus the unforgettable events and colorful personalities that would help shape modern intelligence. Blending the lively pace and compelling detail that are the hallmarks of Erik Larson’s bestsellers with the atmosphere and intensity of The Imitation Game, The Woman Who Smashed Codes is page-turning popular history at its finest.
