Download or read book Lorenz written by Jerry Roberts and published by The History Press. This book was released on 2017-03-02 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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.

Download or read book The Forgotten Giant of Bletchley Park written by Harold Liberty and published by Pen and Sword Military. This book was released on 2022-07-20 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the work of the Bletchley Park codebreakers has caught the public’s imagination with books and films. While men such as Alan Turing and Dilly Knox have been recognized, Brigadier John Tiltman has been hardly mentioned. This overdue biography reveals that ‘The Brig’, as he was known, played a key role. After distinguished Great War military service, he established himself as a skilled codebreaker between the Wars, monitoring Russian and other unfriendly powers’ messages. During World War Two he was regarded as the most versatile of cryptographers, cracking a range of codes including Japanese ones. He made the first breakthrough against the German High Command Lorenz system and what he found led to the creation of machines including Colossus, the first recognisable computer. His lack of recognition may be down to his apparent lack of association with Enigma but, in truth, he was closely involved at the start. In addition to his cryptological brilliance, ‘The Brig’ was a gifted communicator and team-builder whose character combined charm, intelligence, determination and common sense. He was key to building the special relationship with our American partners both during and after the war. Harold Liberty’s biography shines light on a man whose contribution was essential to Britain’s survival and triumph in the Second World War.

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.
Download or read book The Computable City written by Michael Batty and published by MIT Press. This book was released on 2024-03-26 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: How computers simulate cities and how they are also being embedded in cities, changing our behavior and the way in which cities evolve. At every stage in the history of computers and communications, it is safe to say we have been unable to predict what happens next. When computers first appeared nearly seventy-five years ago, primitive computer models were used to help understand and plan cities, but as computers became faster, smaller, more powerful, and ever more ubiquitous, cities themselves began to embrace them. As a result, the smart city emerged. In The Computable City, Michael Batty investigates the circularity of this peculiar evolution: how computers and communications changed the very nature of our city models, which, in turn, are used to simulate systems composed of those same computers. Batty first charts the origins of computers and examines how our computational urban models have developed and how they have been enriched by computer graphics. He then explores the sequence of digital revolutions and how they are converging, focusing on continual changes in new technologies, as well as the twenty-first-century surge in social media, platform economies, and the planning of the smart city. He concludes by revisiting the digital transformation as it continues to confound us, with the understanding that the city, now a high-frequency twenty-four-hour version of itself, changes our understanding of what is possible.

Download or read book The Enigma Girls How Ten Teenagers Broke Ciphers Kept Secrets and Helped Win World War II Scholastic Focus written by Candace Fleming and published by Scholastic Inc.. This book was released on 2024-03-05 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: With numerous starred reviews and accolades, from award-winning author Candace Fleming, comes the powerful and fascinating story of the brave and dedicated young women who helped turn the tides of World War II for the Allies, with their hard work and determination at Bletchley Park. "Events are brought to dramatic life through a treasure trove of photographs--which show the goings-on at Bletchley and the sobering progress of the war--and through the author's meticulous research." -- The New York Times Book Review "You are to report to Station X at Bletchley Park, Buckinghamshire, in four days time....That is all you need to know." This was the terse telegram hundreds of young women throughout the British Isles received in the spring of 1941, as World War II raged. As they arrived at Station X, a sprawling mansion in a state of disrepair surrounded by Spartan-looking huts with little chimneys coughing out thick smoke-these young people had no idea what kind of work they were stepping into. Who had recommended them? Why had they been chosen? Most would never learn all the answers to these questions. Bletchley Park was a well-kept secret during World War II, operating under the code name Station X. The critical work of code-cracking Nazi missives that went on behind its closed doors could determine a victory or loss against Hitler's army. Amidst the brilliant cryptographers, flamboyant debutantes, and absent-minded professors working there, it was teenaged girls who kept Station X running. Some could do advanced math, while others spoke a second language. They ran the unwieldy bombe machines, made sense of wireless sound waves, and sorted the decoded messages. They were expected to excel in their fields and most importantly: know how to keep a secret. Candace Fleming is the award-winning and highly acclaimed author of Crash from Outer Space, The Curse of the Mummy, and many other nonfiction books for young readers. With her canny and compelling narrative voice she makes history come alive. The recipient of five starred reviews, and thick with tension and suspense, The Enigma Girls is an extraordinary and relatively unknown story of World War II that will fascinate readers who will be thrilled to see young people playing such an important role in the wartime effort. Scholastic Focus is the premier home of thoroughly researched, beautifully written, and thoughtfully designed works of narrative nonfiction aimed at middle-grade and young adult readers. These books help readers learn about the world in which they live and develop their critical thinking skills, so that they may become dynamic citizens who are able to analyze and understand our past, participate in essential discussions about our present, and work to grow and build our future. Praise for The Enigma Girls: "Events are brought to dramatic life through a treasure trove of photographs--which show the goings-on at Bletchley and the sobering progress of the war--and through the author's meticulous research." -- The New York Times Book Review * "A thrilling account... Fleming does it again! [T]his compelling blend of WWII, cryptography, and women's history... will mesmerize middle schoolers and inspire them to make an indelible impact on history, too." -- School Library Journal, starred review * "Fleming delivers a fascinating and cohesive overview of Bletchley Park's necessarily siloed, collaborative inner workings that reveals how the figures' ardent efforts affected the outcome of WWII." -- Publishers Weekly, starred review * "In this absorbing book, Fleming approaches the subject by telling the individual stories of 10 young women... who left their homes to work secretly on projects related to the German military's Enigma cipher machine. Even readers with little interest in codes and ciphers will find the women's experiences intriguing." -- Booklist, starred review * "This compulsively readable, compellingly written book will appeal to a broad audience, from readers already interested in World War II to those who are new to the subject." -- Kirkus Reviews, starred review * "[This] is a fascinating and emotionally moving perspective on the well-trod ground of WWII, carefully balanced and rich with details of technology, history, and humanity. This book is not just about deciphering the Enigma messages, however, as it peels back the mythological layers of history to depict the people, technology, mind-numbing mundanity, and heartbreaking tragedy of the war machine." -- The Bulletin of the Center for Children's Books, starred review

Download or read book Churchill Master and Commander written by Anthony Tucker-Jones and published by Bloomsbury Publishing. This book was released on 2021-11-25 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Masterful research, impeccable detail, with a beautifully flowing narrative of which Churchill himself would have been proud.' - Professor Peter Caddick-Adams From his earliest days Winston Churchill was an extreme risk taker and he carried this into adulthood. Today he is widely hailed as Britain's greatest wartime leader and politician. Deep down though, he was foremost a warlord. Just like his ally Stalin, and his arch enemies Hitler and Mussolini, Churchill could not help himself and insisted on personally directing the strategic conduct of World War II. For better or worse he insisted on being political master and military commander. Again like his wartime contemporaries, he had a habit of not heeding the advice of his generals. The results of this were disasters in Norway, North Africa, Greece and Crete during 1940–41. His fruitless Dodecanese campaign in 1943 also ended in defeat. Churchill's pig-headedness over supporting the Italian campaign in defiance of the Riviera landings culminated in him threatening to resign and bring down the British Government. Yet on occasions he got it just right: his refusal to surrender in 1940, the British miracle at Dunkirk and victory in the Battle of Britain, showed that he was a much-needed decisive leader. Nor did he shy away from difficult decisions, such as the destruction of the French Fleet to prevent it falling into German hands and his subsequent war against Vichy France. In this fascinating new book, acclaimed historian Anthony Tucker-Jones explores the record of Winston Churchill as a military commander, assessing how the military experiences of his formative years shaped him for the difficult military decisions he took in office. This book assesses his choices in the some of the most controversial and high-profile campaigns of World War II, and how in high office his decision making was both right and wrong.
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.
Download or read book The Last Cambridge Spy written by Chris Smith and published by The History Press. This book was released on 2019-05-13 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: John Cairncross was among the most damaging spies of the twentieth century. A member of the infamous Cambridge Ring of Five, he leaked highly sensitive documents from Bletchley Park, MI6 and the Treasury to the Soviet Union – including the first atomic secrets and raw decrypts from Enigma and Tunny that influenced the outcome of the Battle of Kursk. In 2014, Cairncross appeared as a secondary, though key, character in the biopic of Alan Turing's life, The Imitation Game. While the other members of the Cambridge Ring of Five have been the subject of extensive biographical study, Cairncross has largely been overlooked by both academic and popular writers. Despite clear interest, he has remained a mystery – until now. The Last Cambridge Spy is the first ever biography of John Cairncross, using newly released material to tell the story of his life and espionage.
Download or read book Between Five Eyes written by Anthony R. Wells and published by Casemate Publishers. This book was released on 2020-09-30 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: “A fascinating insider’s account” of the decades-long intelligence sharing relationship among the US, UK, Canada, Australia, and New Zealand (Perspectives on Terrorism). UK/US intelligence and the wider Five Eyes community of Canada, Australia, and New Zealand is primarily about one thing: relationships. In this remarkable book, Anthony Wells charts fifty years of change, turmoil, intense challenges, successes and failures, and abiding Five Eyes relationships. He traces the development of institutions that he firmly believes have sustained, and indeed may have saved, Western democracies and their allies from those ill disposed to the value system and culture of our nations. More than a chronology of the UK/US intelligence community during this fifty-year period, it is also a personal insight into key relationships and the abiding strength of the United States and the United Kingdom and its Five Eyes allies relationships. The author is the only living person to have worked for British Intelligence as a British citizen and US Intelligence as a US citizen. As a fully trained and accredited security officer for two US intelligence organizations, Wells has relied on his own extensive unclassified collection of papers, personal notes and diaries, as well as his family library, for source material to create this book. “Few people are as uniquely well equipped as Anthony Wells to write an account of these close and special relationships. His penetrating and informed analysis offers us all hope for the continuance of an alliance which makes the world a safer place.” —Vice Admiral Sir Jeremy Blackham, Knight Commander of the Bath, editor, The Naval Review
Download or read book The Pursuit of Peace Science Law and Art written by Anthony R. Wells and published by Xlibris Corporation. This book was released on 2024-03-21 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: 2022-2023 witnessed tragedies on a huge scale precipitated by human weakness, folly, and wickedness, exacerbated by nature that caused catastrophic earthquakes, hurricanes, floods, and destruction and loss of life on enormous scales. Dominating this era of destruction was the February, 2022 Russian invasion of Ukraine followed in October, 2023 by a Middle East crisis and war of enormous proportions. These events brought into sharp focus the precipitous, reckless, and thoroughly evil actions of a relatively very small number of human beings that led and instigated actions that have caused the deaths of hundreds of thousands of innocent human beings, caught up in events not of their choosing. The sum of the parts make the whole, and each of us, each individual can make a difference. We can collectively change the world for the better, countering the evil worst intentions and actions of those who precipitate death, destruction, and human suffering on enormous scales. History is replete with those who made a difference and showed and led the way to peace and harmony. This story is about how two individuals, in totally widely different ways, can make a difference. To these two lives is added the dimension of a crucial human endeavor that has marked our progress and development since the earliest times, the role of art as a human virtue, a creative life form that underlies humankind’s ability to come to terms with our existence and our progress through time. The art aspect is very different, seen through the lens of good and bad, and unified in the theme of achieving peace and that which is right after turmoil, and downright evil. The story challenges us to review our world, and what each of us may do to enhance peace, to look beyond the daily routine that most of us follow by the sheer nature of our circumstances and find ways and means by which we may all contribute, albeit perhaps in small, maybe insignificant ways in the greater scheme of things, though nonetheless significant. The reason is simple. Each of us can make a difference in our own individual way, and together, collectively, the sum of us all can truly make a huge difference. The pursuit of peace is not an imagery ideal. It is a fundamental necessity that behooves us all to help maintain for the sake of our world, children, grandchildren and all those whom we love and care about. This story is about hope and how peace can be shaped by positive and courageous human endeavor.
Download or read book Kursk 1943 written by Anthony Tucker-Jones and published by The History Press. This book was released on 2018-05-07 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1943, as war raged along the Eastern Front, the German forces attempted to push further east in the brutal Operation Citadel, which saw one of the largest armoured clashes in history: the Battle of Prokhorovka. Countered by two Soviet attacks, this operation saw the tide turn on the Eastern Front. For the first time a German offensive was halted in its tracks and the Soviets ended the conflict as the decisive victors. With a loss of over 200,000 men on both sides, this two-month clash was one of the costliest of the war. In this dramatic study, Anthony Tucker-Jones reassesses this decisive tank battle through the eyes of those who fought, using translated first-person accounts. Kursk 1943 is one volume that no military history enthusiast should be without.
