Book Description
The award-winning New York Times bestseller about the American women who secretly served as codebreakers during World War II--a "prodigiously researched and engrossing" (New York Times) book that "shines a light on a hidden chapter of American history" (Denver Post). Recruited by the U.S. Army and Navy from small towns and elite colleges, more than ten thousand women served as codebreakers during World War II. While their brothers and boyfriends took up arms, these women moved to Washington and learned the meticulous work of code-breaking. Their efforts shortened the war, saved countless lives, and gave them access to careers previously denied to them. A strict vow of secrecy nearly erased their efforts from history; now, through dazzling research and interviews with surviving code girls, bestselling author Liza Mundy brings to life this riveting and vital story of American courage, service, and scientific accomplishment.

Joe Rochefort's War

Joe Rochefort's War PDF Author: Elliot W Carlson
Publisher: Naval Institute Press
ISBN: 1612510736
Category : History
Languages : en
Pages : 626

Book Description
Elliot Carlson’s award-winning biography of Capt. Joe Rochefort is the first to be written about the officer who headed Station Hypo, the U.S. Navy’s signals monitoring and cryptographic intelligence unit at Pearl Harbor, and who broke the Japanese navy’s code before the Battle of Midway. The book brings Rochefort to life as the irreverent, fiercely independent, and consequential officer that he was. Readers share his frustrations as he searches in vain for Yamamoto’s fleet prior to the Japanese attack on Pearl Harbor, but share his joy when he succeeds in tracking the fleet in early 1942 and breaks the code that leads Rochefort to believe Yamamoto’s invasion target is Midway. His conclusions, bitterly opposed by some top Navy brass, are credited with making the U.S. victory possible and helping to change the course of the war. The author tells the story of how opponents in Washington forced Rochefort’s removal from Station Hypo and denied him the Distinguished Service Medal recommended by Admiral Nimitz. In capturing the interplay of policy and personality and the role played by politics at the highest levels of the Navy, Carlson reveals a side of the intelligence community seldom seen by outsiders. For a full understanding of the man, Carlson examines Rochefort’s love-hate relationship with cryptanalysis, his adventure-filled years in the 1930s as the right-hand man to the Commander in Chief of the U.S. Fleet, and his return to codebreaking in mid-1941 as the officer in charge of Station Hypo. He traces Rochefort’s career from his enlistment in 1918 to his posting in Washington as head of the Navy’s codebreaking desk at age twenty-five, and beyond. In many ways a reinterpretation of Rochefort, the book makes clear the key role his codebreaking played in the outcome of Midway and the legacy he left of reporting actionable intelligence directly to the fleet. An epilogue describes efforts waged by Rochefort’s colleagues to obtain the medal denied him in 1942—a drive that finally paid off in 1986 when the medal was awarded posthumously.

The Secret Code-Breakers of Central Bureau

The Secret Code-Breakers of Central Bureau PDF Author: David Dufty

ISBN: 9781761380327

Languages : en
Pages : 0

Book Description
Central Bureau - Australia's own large and sophisticated intelligence network, built from scratch. It was this group of mathematicians, code-breakers, and radio experts who intercepted the travel plans of the architect of the Pearl Harbor attack, Admiral Yamamoto, leading to his ambush and death. Australian signals intelligence also played a vital role in the battles of the Coral Sea, Milne Bay, Hollandia, and many others. General Douglas MacArthur, the supreme commander of the local Allied forces, went so far as to insist that the men of Central Bureau accompany him on his counter-attack in the Pacific. After the war, the US sought to give these non-combatants the highest awards possible - honours that were suppressed by the Australian government in their need for secrecy. A groundbreaking work of military history, The Secret Code-breakers of Central Bureau gives these talented and dedicated individuals their due at last. It is a rich account of the shadowy side of military strength and of the men and women whose work was, in the words of the US navy, of 'immeasurable importance in the successfulmprosecution' of the Pacific War. 'Who knew? This enthralling study tells a deeply human story. The men and women who gave our troops a significant edge in the fight against the Japanese are the genuine heroes in this engaging and exciting book.' -Michael McKernan, author of The Strength of a Nation and When This Thing Happened 'This is history and military strategy written at its most engaging.' -Waikato Times 'A delightfully and thoroughly engaging story of the emergence of the Australian contribution to the signals and radio interception intelligence ... Dufty's writing style is light and easy to read, reminiscent of other contemporary historical narratives that tell a series of stories, most notably the emphasis of the human story associated with these experiences.' -Rhys Ball, NZ International Review

Code Warriors

Code Warriors PDF Author: Stephen Budiansky
Publisher: Knopf
ISBN: 0385352662
Category : Cryptography
Languages : en
Pages : 433

Book Description
In Code Warriors, Stephen Budiansky--a longtime expert in cryptology--tells the fascinating story of how NSA came to be, from its roots in World War II through the fall of the Berlin Wall. Along the way, he guides us through the fascinating challenges faced by cryptanalysts, and how they broke some of the most complicated codes of the twentieth century. With access to new documents, Budiansky shows where the agency succeeded and failed during the Cold War, but his account also offers crucial perspective for assessing NSA today in the wake of the Edward Snowden revelations. Budiansky shows how NSA's obsession with recording every bit of data and decoding every signal is far from a new development; throughout its history the depth and breadth of the agency's reach has resulted in both remarkable successes and destructive failures.

Pages : 431

Book Description
“What would it be like to keep a secret for fifty years? Never telling your parents, your children, or even your husband?” Codebreaker Girls: A Secret Life at Bletchley Park tells the true story of Daisy Lawrence. Following extensive research, the author uses snippets of information, unpublished photographs and her own recollections to describe scenes from her mother’s poor, but happy, upbringing in London, and the disruptions caused by the outbreak of the Second World War to a young woman in the prime of her life. The author asks why, and how, Daisy was chosen to work at the Government war station, as well as the clandestine operation she experienced with others, deep in the British countryside, during a time when the effects of the war were felt by everyone. In addition, the author examines her mother’s personal emotions and relationships as she searches for her young fiancée, who was missing in action overseas. The three years at Bletchley Park were Daisy’s university, but having closed the door in 1945 on her hidden role of national importance — dealing with Germany, Italy and Japan — this significant period in her life was camouflaged for decades in the filing cabinet of her mind. Now her story comes alive with descriptions, original letters, documents, newspaper cuttings and unique photographs, together with a rare and powerful account of what happened to her after the war. “Here’s a beauty of a history of some of the codebreaking girls who helped save us during the second world war. This one’s about Daisy Lawrence’s extraordinary life as a poor girl brought up in London and then chosen for top secret work at Bletchley Park. Reads like fiction.” —Books Monthly

Lorenz PDF Author: Jerry Roberts
Publisher: The History Press
ISBN: 0750982047
Category : Biography & Autobiography
Languages : en
Pages : 300

Book Description
The breaking of the Enigma machine is one of the most heroic stories of the Second World War and highlights the crucial work of the codebreakers of Bletchley Park, which prevented Britain's certain defeat in 1941. But there was another German cipher machine, used by Hitler himself to convey messages to his top generals in the field. A machine more complex and secure than Enigma. A machine that could never be broken. For sixty years, no one knew about Lorenz or 'Tunny', or the determined group of men who finally broke the code and thus changed the course of the war. Many of them went to their deaths without anyone knowing of their achievements. Here, for the first time, senior codebreaker Captain Jerry Roberts tells the complete story of this extraordinary feat of intellect and of his struggle to get his wartime colleagues the recognition they deserve. The work carried out at Bletchley Park during the war to partially automate the process of breaking Lorenz, which had previously been done entirely by hand, was groundbreaking and is recognised as having kick-started the modern computer age.
