Available in PDF, EPUB and Kindle. Book excerpt: The thrilling true story of Agent A12, the earliest enemy of the Nazis, and the first spy to crack Hitler’s deadliest secret code: the framework of the Final Solution. In public life, Dr. Winthrop Bell was a Harvard philosophy professor and wealthy businessman. As an MI6 spy—known as secret agent A12—in Berlin in 1919, he evaded gunfire and shook off pursuers to break open the emerging Nazi conspiracy. His reports, the first warning of the Nazi plot for World War II, went directly to the man known as C, the mysterious founder of MI6, as well as to various prime ministers. But a powerful fascist politician quietly worked to suppress his alerts. Nevertheless, Dr. Bell's intelligence sabotaged the Nazis, in ways only now revealed in Cracking the Nazi Code. As World War II approached, Bell became a spy once again. In 1939, he was the first to crack Hitler’s deadliest secret code: Germany’s plan for the Holocaust. At that time, the führer was a popular politician who said he wanted peace. Could anyone believe Bell’s shocking warning? Fighting an epic intelligence war from Eastern Europe and Russia to France, Canada, and finally Washington, DC, agent A12 was a real-life 007, waging a single-handed struggle against fascists bent on destroying the Western world. Without Bell’s astounding courage, the Nazis just might have won the war.

Available in PDF, EPUB and Kindle. Book excerpt: Alan Turing: Enigma: The Incredible True Story of the Man Who Cracked The Code If you have ever used a computer, you owe that joy to Alan Turing. Turing is known by many as the Father of the Modern Computer for his conception of the theoretical stored-memory machine (known as the Turing Machine) and for the subsequent implementation of this idea in the creation of some of the world's first working computers, the Automatic Computing Engine, and the Manchester Mark 1. Impressive as they are, though, Turing's contributions to computer science are not necessarily his most famous or influential projects. Alan Turing was one of the most significant figures in the Allied victory of World War Two, thanks to his ingenious code breaking skills and the invention of the British Bombe at Bletchley Park. In his later life, Turing even dabbled in artificial intelligence, and biology, creating concepts that are still being investigated today. Until recently, Alan Turing had often been overlooked as an important figure in history. Thanks to in-depth biographies like Andrew Hodges' Alan Turing: The Enigma, and film depictions of Turing's life, like The Imitation Game, based on Hodges' book, Alan Turing is quickly becoming a household name, as people begin to recognize that his contributions to various fields were so influential they actually changed the course of human history.

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.

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 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.

Available in PDF, EPUB and Kindle. Book excerpt: Bletchley Park was where one of the war’s most famous – and crucial – achievements was made: the cracking of Germany’s “Enigma” code in which its most important military communications were couched. This country house in the Buckinghamshire countryside was home to Britain’s most brilliant mathematical brains, like Alan Turing, and the scene of immense advances in technology – indeed, the birth of modern computing. The military codes deciphered there were instrumental in turning both the Battle of the Atlantic and the war in North Africa. But, though plenty has been written about the boffins, and the codebreaking, fictional and non-fiction – from Robert Harris and Ian McEwan to Andrew Hodges’ biography of Turing – what of the thousands of men and women who lived and worked there during the war? What was life like for them – an odd, secret territory between the civilian and the military? Sinclair McKay’s book is the first history for the general reader of life at Bletchley Park, and an amazing compendium of memories from people now in their eighties – of skating on the frozen lake in the grounds (a depressed Angus Wilson, the novelist, once threw himself in) – of a youthful Roy Jenkins, useless at codebreaking, of the high jinks at nearby accommodation hostels – and of the implacable secrecy that meant girlfriend and boyfriend working in adjacent huts knew nothing about each other’s work.

Available in PDF, EPUB and Kindle. Book excerpt: National Bestseller NPR Best Book of the Year “Not all superheroes wear capes, and Elizebeth Smith Friedman should be the subject of a future Wonder Woman movie.” —The New York Times Joining the ranks of Hidden Figures and In the Garden of Beasts, the incredible true story of the greatest codebreaking duo that ever lived, an American woman and her husband who invented the modern science of cryptology together and used it to confront the evils of their time, solving puzzles that unmasked Nazi spies and helped win World War II. In 1916, at the height of World War I, brilliant Shakespeare expert Elizebeth Smith went to work for an eccentric tycoon on his estate outside Chicago. The tycoon had close ties to the U.S. government, and he soon asked Elizebeth to apply her language skills to an exciting new venture: code-breaking. There she met the man who would become her husband, groundbreaking cryptologist William Friedman. Though she and Friedman are in many ways the "Adam and Eve" of the NSA, Elizebeth’s story, incredibly, has never been told. In The Woman Who Smashed Codes, Jason Fagone chronicles the life of this extraordinary woman, who played an integral role in our nation’s history for forty years. After World War I, Smith used her talents to catch gangsters and smugglers during Prohibition, then accepted a covert mission to discover and expose Nazi spy rings that were spreading like wildfire across South America, advancing ever closer to the United States. As World War II raged, Elizebeth fought a highly classified battle of wits against Hitler’s Reich, cracking multiple versions of the Enigma machine used by German spies. Meanwhile, inside an Army vault in Washington, William worked furiously to break Purple, the Japanese version of Enigma—and eventually succeeded, at a terrible cost to his personal life. Fagone unveils America’s code-breaking history through the prism of Smith’s life, bringing into focus the unforgettable events and colorful personalities that would help shape modern intelligence. Blending the lively pace and compelling detail that are the hallmarks of Erik Larson’s bestsellers with the atmosphere and intensity of The Imitation Game, The Woman Who Smashed Codes is page-turning popular history at its finest.

Available in PDF, EPUB and Kindle. Book excerpt: A NEW YORK TIMES BESTSELLER The official book behind the Academy Award-winning film The Imitation Game, starring Benedict Cumberbatch and Keira Knightley It is only a slight exaggeration to say that the British mathematician Alan Turing (1912-1954) saved the Allies from the Nazis, invented the computer and artificial intelligence, and anticipated gay liberation by decades--all before his suicide at age forty-one. This New York Times–bestselling biography of the founder of computer science, with a new preface by the author that addresses Turing's royal pardon in 2013, is the definitive account of an extraordinary mind and life. Capturing both the inner and outer drama of Turing’s life, Andrew Hodges tells how Turing’s revolutionary idea of 1936--the concept of a universal machine--laid the foundation for the modern computer and how Turing brought the idea to practical realization in 1945 with his electronic design. The book also tells how this work was directly related to Turing’s leading role in breaking the German Enigma ciphers during World War II, a scientific triumph that was critical to Allied victory in the Atlantic. At the same time, this is the tragic account of a man who, despite his wartime service, was eventually arrested, stripped of his security clearance, and forced to undergo a humiliating treatment program--all for trying to live honestly in a society that defined homosexuality as a crime. The inspiration for a major motion picture starring Benedict Cumberbatch and Keira Knightley, Alan Turing: The Enigma is a gripping story of mathematics, computers, cryptography, and homosexual persecution.

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 excerpt: For the first time, the inside story of the brilliant American engineer who defeated Enigma and the Nazi code-masters Much has been written about the success of the British “Ultra” program in cracking the Germans’ Enigma code early in World War II, but few know what really happened in 1942, when the Germans added a fourth rotor to the machine that created the already challenging naval code and plunged Allied intelligence into darkness. Enter one Joe Desch, an unassuming but brilliant engineer at the National Cash Register Company in Dayton, Ohio, who was given the task of creating a machine to break the new Enigma settings. It was an enterprise that rivaled the Manhattan Project for secrecy and complexity–and nearly drove Desch to a breakdown. Under enormous pressure, he succeeded in creating a 5,000-pound electromechanical monster known as the Desch Bombe, which helped turn the tide in the Battle of the Atlantic–but not before a disgruntled co-worker attempted to leak information about the machine to the Nazis. After toiling anonymously–it even took his daughter years to learn of his accomplishments–Desch was awarded the National Medal of Merit, the country’s highest civilian honor. In The Secret in Building 26, the entire thrilling story of the final triumph over Enigma is finally told. From the Trade Paperback edition.

Book excerpt: In 1936, when he was just twenty-four years old, Alan Turing wrote a remarkable paper in which he outlined the theory of computation, laying out the ideas that underlie all modern computers. This groundbreaking and powerful theory now forms the basis of computer science. In Turing's Vision, Chris Bernhardt explains the theory, Turing's most important contribution, for the general reader. Bernhardt argues that the strength of Turing's theory is its simplicity, and that, explained in a straightforward manner, it is eminently understandable by the nonspecialist. As Marvin Minsky writes, "The sheer simplicity of the theory's foundation and extraordinary short path from this foundation to its logical and surprising conclusions give the theory a mathematical beauty that alone guarantees it a permanent place in computer theory." Bernhardt begins with the foundation and systematically builds to the surprising conclusions. He also views Turing's theory in the context of mathematical history, other views of computation (including those of Alonzo Church), Turing's later work, and the birth of the modern computer. In the paper, "On Computable Numbers, with an Application to the Entscheidungsproblem," Turing thinks carefully about how humans perform computation, breaking it down into a sequence of steps, and then constructs theoretical machines capable of performing each step. Turing wanted to show that there were problems that were beyond any computer's ability to solve; in particular, he wanted to find a decision problem that he could prove was undecidable. To explain Turing's ideas, Bernhardt examines three well-known decision problems to explore the concept of undecidability; investigates theoretical computing machines, including Turing machines; explains universal machines; and proves that certain problems are undecidable, including Turing's problem concerning computable numbers.
