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.

Decode the story of Elizebeth Friedman, the cryptologist who took down gangsters and Nazi spies In this picture book biography, young readers will learn all about Elizebeth Friedman (1892–1980), a brilliant American code breaker who smashed Nazi spy rings, took down gangsters, and created the CIA's first cryptology unit. Her story came to light when her secret papers were finally declassified in 2015. From thwarting notorious rumrunners with only paper and pencil to “counter-spying into the minds and activities of” Nazis, Elizebeth held a pivotal role in the early days of US cryptology. No code was too challenging for her to crack, and Elizebeth’s work undoubtedly saved thousands of lives. Extensive back matter includes explanations of codes and ciphers, further information on cryptology, a bibliography, a timeline of Elizebeth’s life, plus secret messages for young readers to decode.

"Along with a brief explanation of the workings of cipers and cryptanalysts, the computer program that accompanies this book provides a replacement for paper and pencil, which has always been a burdensome requirement in operating on ciphers. I think the tedium of a manual trial and error approach might tend to discourage a newcomer to the world of codes and ciphers. These computer programs take over that task and eliminate the tedium." -From foreword

When Richard Hayes, a gifted polymath and cryptographer, was drafted by Irish intelligence services to track the movements of a prolific Nazi spy, Hermann Görtz, it set in motion one of the most remarkable episodes in Irish history. What followed was a high-stakes game of cat and mouse that would wind its way through the capital and its suburbs, reverberate through the corridors of power, test the sympathies of those in high society, and even expand to jeopardise the Allied war effort.Codebreaker is a riveting and deeply researched account of an extraordinary period of history – when Dublin became a hotbed of Nazi intrigue and the fate of an independent Ireland settled on the shoulders of an unassuming employee of the National Library.

"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.

The extraordinary story of a headmaster turned cryptographer, and our top-secret war with the Kaiser's Reich. On 11 August 1914, just days after war had been declared, Australian Captain J.T. Richardson boarded a German merchant vessel fleeing Melbourne's Port Phillip and audaciously seized a top-secret naval codebook. 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.
