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.

WW2 Codebreaking People and Places is the first volume of a series on a glossary of codebreaking, ‘People and Places’, brings to the reader an easily understandable account and listing, of those involved in collecting and analysing military intelligence, principally during the second world war. while some will be well known, such as Alan Turing, many others have made significant contributions to codebreaking but fail to attract the attention of the media for the most part. From an individual named ‘Wren’ who worked at a codebreaking outstation supporting Bletchley Park, to a mathematician who modified a codebreaking machine just prior to D-Day, to a ladies foundationwear factory in Hertfordshire that helped make machine components, these people and places now can be appreciated as to where they fitted-in within the overall picture of gathering, and processing enemy intelligence in wartime. The entries are cross-referenced to enable the reader to research as much or as little as they want, to dip-in to the glossary, to use it as a basis for further study, or just to learn a little more about the people that helped us win the war with our allied friends. .

"This is the story of the Allied codebreakers puzzling through the most difficult codebreaking problems that ever existed.

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.

“A fascinating account” of the secret Virginia facility code-named PO Box 1142, where the US gathered intelligence and interrogated German prisoners (Journal of Counterterrorism & Homeland Security International). About fifteen miles south of Washington, DC, Fort Hunt, Virginia is a green open space enjoyed by residents. But not so long ago, it was the site of one of the highest-level clandestine operations of World War II. Shortly after the US entered the war, the military realized it had to work on exploiting any advantages it might gain on the Axis Powers. One part of this endeavor was to establish a secret facility not too close to—but also not too far from—the Pentagon, which would interrogate and eavesdrop on the highest-level Nazi prisoners and also translate and analyze captured German war documents. That complex was established at Fort Hunt, known by the code name: PO Box 1142. The American servicemen who did the interrogating and translating were young, bright, hardworking, and absolutely dedicated to their work. Many of them were Jews who’d escaped Nazi Germany as children—some had come to America with their parents, others had escaped alone, but their experiences, and what they’d been forced to leave behind, meant they had personal motivation to do whatever they could to defeat Nazi Germany. They were perfect for the difficult and complex job at hand. They never used corporal punishment in interrogations of German soldiers but developed and deployed dozens of tricks to gain information. The Allies won the war against Hitler for a host of reasons, discussed in hundreds of volumes. This is the first book to describe the intelligence operations at PO Box 1142 and their part in that success. It will never be known how many American lives were spared, or whether the war ended sooner with the programs at Fort Hunt, but it’s doubtless that they made a difference—and gave the young Jewish men stationed there the chance to combat the evil that had befallen them and their families. “Fills a gap in World War II intelligence history by documenting the origins of a number of European Theater intelligence successes thanks to the work of Ft. Hunt interrogators.” —Studies in Intelligence Includes photographs

Discover the true stories of code breakers who worked behind the scenes during World War II. Men and women cracked enemy codes in order to gain information that helped the Allies win the war.

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.
