Book excerpt: 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.

Download or read book Enigma written by Hugh Sebag-Montefiore and published by Weidenfeld & Nicolson. This book was released on 2011-07-21 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: The complete story of how the German Enigma codes were broken. Perfect for fans of THE IMITATION GAME, the new film on Alan Turing's Enigma code, starring Benedict Cumberbatch. Breaking the German Enigma codes was not only about brilliant mathematicians and professors at Bletchley Park. There is another aspect of the story which it is only now possible to tell. It takes in the exploits of spies, naval officers and ordinary British seamen who risked, and in some cases lost, their lives snatching the vital Enigma codebooks from under the noses of Nazi officials and from sinking German ships and submarines. This book tells the whole Enigma story: its original invention and use by German forces and how it was the Poles who first cracked - and passed on to the British - the key to the German airforce Enigma. The more complicated German Navy Enigma appeared to them to be unbreakable.
Download or read book Geniuses at War written by David A. Price and published by Knopf. This book was released on 2021-06-22 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dramatic, untold story of the brilliant team whose feats of innovation and engineering created the world’s first digital electronic computer—decrypting the Nazis’ toughest code, helping bring an end to WWII, and ushering in the information age. • Winner, Institute of Electrical and Electronics Engineers Middleton Award for "a book ... that both exemplifies exceptional scholarship and reaches beyond academic communities toward a broad public audience." • A Kirkus Best Book of 2022 • Planning the invasion of Normandy, the Allies knew that decoding the communications of the Nazi high command was imperative for its success. But standing in their way was an encryption machine they called Tunny (British English for “tuna”), which was vastly more difficult to crack than the infamous Enigma cipher. To surmount this seemingly impossible challenge, Alan Turing, the Enigma codebreaker, brought in a maverick English working-class engineer named Tommy Flowers who devised the ingenious, daring, and controversial plan to build a machine that would calculate at breathtaking speed and break the code in nearly real time. Together with the pioneering mathematician Max Newman, Flowers and his team produced—against the odds, the clock, and a resistant leadership—Colossus, the world’s first digital electronic computer, the machine that would help bring the war to an end. Drawing upon recently declassified sources, David A. Price’s Geniuses at War tells, for the first time, the full mesmerizing story of the great minds behind Colossus and chronicles the remarkable feats of engineering genius that marked the dawn of the digital age.

Book Synopsis Code Warriors by : Stephen Budiansky
Download or read book Code Warriors written by Stephen Budiansky and published by Knopf. This book was released on 2016 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Before Bletchley Park by : Paul Gannon
Download or read book Before Bletchley Park written by Paul Gannon and published by The History Press. This book was released on 2020-10-23 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: The story of Bletchley Park's codebreaking operations in the Second World War is now well known, but its counterparts in the First World War – Room 40 & MI1(b) – remain in the shadows, despite their involvement in and influence on most of the major events of that war. From the First Battle of the Marne, the shelling of Scarborough, the battles of Jutland and the Somme in 1916, to the battles on the Western Front in 1918, the German naval mutiny and the Zimmermann Telegram, this cast of characters – several of them as eccentric as anyone from Bletchley Park in the Second World War – secretly guided the outcome of the 'Great War' from the confines of a few smoke-filled rooms. Using hundreds of intercepted and decrypted German military, naval and diplomatic messages, bestselling author Paul Gannon reveals the fascinating story of British codebreaking operations. By drawing on many newly discovered archival documents that challenge misleading stories about Room 40 & MI1(b), he reveals a sophisticated machine in operation.

The fledgling Australian Navy had an opportunity to immediately change the course of the war. But what exactly had they found? Enter the Australian code breakers ... Recruited by savvy top brass, maths whizz and German speaker Frederick Wheatley worked night and day to fathom the basic principles of the code and start tracking the German Navy's powerful East Asia Squadron, led by the brilliant Maximilian von Spee. Soon Melbourne was a hub of international Allied intelligence. This is the untold story of how a former Australian headmaster and his mostly female team cracked one of Germany's most complex codes, paving the way for the greatest Allied naval victory of World War I.

Download or read book Seizing the Enigma written by David Kahn and published by Frontline Books. This book was released on 2012-02-02 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: “An absorbing and thoroughly well documented account” of WWII naval intelligence and the Allied hunt for the Nazi code machine known as the Enigma (Warship). From the start of World War II to mid-1943, British and American naval forces fought a desperate battle against German submarine wolfpacks. And the Allies might have lost the struggle at sea without an astounding intelligence coup. Here, the author brings to life the race to break the German U-boat codes. As the Battle of the Atlantic raged, Hitler’s U-boats reigned. To combat the growing crisis, ingenious amateurs joined the nucleus of dedicated professionals at Bletchley Park to unlock the continually changing German naval codes. Their mission: to read the U-boat messages of Hitler’s cipher device, the Enigma. They first found success with the capture of U-110,—which yielded the Enigma machine itself and a trove of secret documents. Then the weather ship Lauenburg seized near the Arctic ice pack provided code settings for an entire month. Finally, two sailors rescued a German weather cipher that enabled the team at Bletchley to solve the Enigma after a year-long blackout. In “a highly recommended account with a wealth of materials” Seizing the Enigma tells the story of a determined corps of people who helped turn the tide of the war (Naval Historical Foundation).

Book Synopsis Joe Rochefort's War by : Elliot W Carlson
Download or read book Joe Rochefort's War written by Elliot W Carlson and published by Naval Institute Press. This book was released on 2013-09-15 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: “The reigning queen of historical fiction” -- Fiona Davis, New York Times bestselling author of The Lions of Fifth Avenue The New York Times and USA Today bestselling author of The Huntress and The Alice Network returns with another heart-stopping World War II story of three female code breakers at Bletchley Park and the spy they must root out after the war is over. 1940. As England prepares to fight the Nazis, three very different women answer the call to mysterious country estate Bletchley Park, where the best minds in Britain train to break German military codes. Vivacious debutante Osla is the girl who has everything—beauty, wealth, and the dashing Prince Philip of Greece sending her roses—but she burns to prove herself as more than a society girl, and puts her fluent German to use as a translator of decoded enemy secrets. Imperious self-made Mab, product of east-end London poverty, works the legendary codebreaking machines as she conceals old wounds and looks for a socially advantageous husband. Both Osla and Mab are quick to see the potential in local village spinster Beth, whose shyness conceals a brilliant facility with puzzles, and soon Beth spreads her wings as one of the Park’s few female cryptanalysts. But war, loss, and the impossible pressure of secrecy will tear the three apart. 1947. As the royal wedding of Princess Elizabeth and Prince Philip whips post-war Britain into a fever, three friends-turned-enemies are reunited by a mysterious encrypted letter--the key to which lies buried in the long-ago betrayal that destroyed their friendship and left one of them confined to an asylum. A mysterious traitor has emerged from the shadows of their Bletchley Park past, and now Osla, Mab, and Beth must resurrect their old alliance and crack one last code together. But each petal they remove from the rose code brings danger--and their true enemy--closer...
Book Synopsis Codebreaking and Signals Intelligence by : Christopher Andrew
Download or read book Codebreaking and Signals Intelligence written by Christopher Andrew and published by Taylor & Francis. This book was released on 2021-05-30 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite publicity given to the successes of British and American codebreakers during the Second World War, the study of signals intelligence is still complicated by governmental secrecy over even the most elderly peacetime sigint. This book, first published in 1986, lifts the veil on some of these historical secrets. Christopher Andrew and Keith Neilson cast new light on how Tsarist codebreakers penetrated British code and cypher systems. John Chapman’s study of German military codebreaking represents a major advance in our understanding of cryptanalysis during the Weimar Republic. The history of the Government Code and Cypher School – forerunner of today’s GCHQ – by its operational head, the late A.G. Denniston, provides both a general assessment of the achievements of British cryptanalysis between the wars and a tantalising glimpse of what historians may one day find in GCHQ’s forbidden archives. The distinguished cryptanalyst of Bletchley Park, the late Gordon Welchman, describes in detail how the Ultra programme defeated the German Enigma machine, while another Bletchley Park cryptographer, Christopher Morris, reminds us in his account of the valuable work on hand cyphers that wartime sigint consisted of much more than Ultra. Roger Austin’s study of surveillance under the Vichy regime shows the continuing importance of older and simpler methods of message interception such as letter-opening. Taken together, the articles establish sigint as an essential field of study for both the modern historian and the political scientist.
Download or read book X, Y and Z written by Dermot Turing and published by The History Press. This book was released on 2018-09-03 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: December, 1932 In the bathroom of a Belgian hotel, a French spymaster photographs top-secret documents – the operating instructions of the cipher machine, Enigma. A few weeks later a mathematician in Warsaw begins to decipher the coded communications of the Third Reich and lays the foundations for the code-breaking operation at Bletchley Park. The co-operation between France, Britain and Poland is given the cover-name 'X, Y & Z'. December, 1942 It is the middle of World War Two. The Polish code-breakers have risked their lives to continue their work inside Vichy France, even as an uncertain future faces their homeland. Now they are on the run from the Gestapo. People who know the Enigma secret are not supposed to be in the combat zone, so MI6 devises a plan to exfiltrate them. If it goes wrong, if they are caught, the consequences could be catastrophic for the Allies. Based on original research and newly released documents, X, Y & Z is the exhilarating story of those who risked their lives to protect the greatest secret of World War Two.
