Engineering is everywhere, from the Large Hadron Collider to invisibly small circuits on silicon chips. The 50 Greatest Engineers celebrates the great achievements that have been made through the ages, containing profiles of the best-known and most innovative engineers of all time.

Alan Turing was an extraordinary man who crammed into a life of only 42 years the careers of mathematician, codebreaker, computer scientist and biologist. He is widely regarded as a war hero grossly mistreated by his unappreciative country, and it has become hard to disentangle the real man from the story. It is easy to cast him as a misfit, the stereotypical professor.

Only days after the Japanese attacked Pearl Harbor, President Franklin D. Roosevelt tapped Chester W. Nimitz to assume command of the Pacific Fleet. Nimitz transformed the devastated and dispirited Pacific fleet into the most powerful and commanding naval force in history. Facing demands from Washington to mount an early offensive, he had first to revive the depressed morale of the thousands of sailors, soldiers, and Marines who served under him. And of course, he also confronted a formidable and implacable enemy in the Imperial Japanese Navy.

The Second World War changed the course of modern history. It is filled with incredible stories of daring risks and exceptional struggles, but in the popular imagination, these stories are more often than not the stories of men. There is, however, a hidden treasure trove of untold stories of heroic women who have risked their lives in the monumental battle against fascism. We’ve heard of women who became nurses treating soldiers with battlefield injuries, partisans who fought occupying armies, and skilled laborers who worked in wartime industries.

Robert Oppenheimer was among the most brilliant and divisive of men. As head of the Los Alamos Laboratory, he oversaw the successful effort to beat the Nazis in the race to develop the first atomic bomb – a breakthrough that was to have eternal ramifications for mankind and that made Oppenheimer the “Father of the Atomic Bomb.” But with his actions leading up to that great achievement, he also set himself on a dangerous collision course with Senator Joseph McCarthy and his witch-hunters. In Robert Oppenheimer: A Life Inside the Center, Ray Monk, author of peerless biographies of Ludwig Wittgenstein and Bertrand Russell, goes deeper than any previous biographer in the quest to solve the enigma of Oppenheimer’s motivations and his complex personality.

Historian and broadcaster Tessa Dunlop tells the story of the women of Bletchley Park through exclusive and unprecedented access to the women themselves. The Bletchley Girls weaves together the lives of 15 women who were all selected to work in Britain's most secret organisation - Bletchley Park. It is their story, told in their voices; Tessa met and talked to 15 veterans, often visiting them several times. Firm friendships were made as their epic journey unfolded on paper.

The National Security Agency was born out of the legendary codebreaking programs of World War II that cracked the famed Enigma machine and other German and Japanese codes, thereby turning the tide of Allied victory. In the postwar years, as the United States developed a new enemy in the Soviet Union, our intelligence community found itself targeting not soldiers on the battlefield, but suspected spies, foreign leaders, and even American citizens.

Ben Macintyre’s Agent Zigzag was hailed as “rollicking, spellbinding” (New York Times), “wildly improbable but entirely true” (Entertainment Weekly), and, quite simply, “the best book ever written” (Boston Globe). In his new book, Operation Mincemeat, he tells an extraordinary story that will delight his legions of fans. In 1943, from a windowless basement office in London, two brilliant intelligence officers conceived a plan that was both simple and complicated - Operation Mincemeat.

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.

J. Robert Oppenheimer was one of the iconic figures of the 20th century, a brilliant physicist who led the effort to build the atomic bomb but later confronted the moral consequences of scientific progress. When he proposed international controls over atomic materials, opposed the development of the hydrogen bomb, and criticized plans for a nuclear war, his ideas were anathema to powerful advocates of a massive nuclear buildup during the anti-Communist hysteria of the early 1950s.

Only four men in American history have been promoted to the five-star rank of Admiral of the Fleet: William Leahy, Ernest King, Chester Nimitz, and William Halsey. These four men were the best and the brightest the navy produced, and together they led the U.S. Navy to victory in World War II, establishing the United States as the world's greatest fleet. In The Admirals, award-winning historian Walter R. Borneman tells their story in full detail for the first time.

1942: World War II is in full swing. Odette Sansom decides to follow in her war hero father’s footsteps by becoming an SOE agent to aid Britain and her beloved homeland, France. Five failed attempts and a plane crash later, she finally lands in occupied France to begin her mission. It is here that she meets her commanding officer, Captain Peter Churchill. As they successfully complete mission after mission, Peter and Odette fall in love. All the while, they are being hunted by the cunning German secret police sergeant, Hugo Bleicher, who finally succeeds in capturing them.

Britain's Special Air Service - or SAS - was the brainchild of David Stirling, a young, gadabout aristocrat whose aimlessness in early life belied a remarkable strategic mind. Where most of his colleagues looked at a battlefield map of World War II's African theater and saw a protracted struggle with Rommel's desert forces, Stirling saw an opportunity: Given a small number of elite, well-trained men, he could parachute behind enemy lines and sabotage their airplanes and war matériel.

As riveting as a World War II thriller, The Forger's Spell is the true story of Johannes Vermeer and the small-time Dutch painter who dared to impersonate him centuries later. For seven years a no-account painter named Han van Meegeren managed to pass off his paintings as those of one of the most beloved and admired artists who ever lived. As Edward Dolnick reveals, his true genius lay in psychological manipulation, and he came within inches of fooling the world. Instead, he landed in an Amsterdam court on trial for his life.

In 1943, as the war against Nazi Germany raged abroad, President Franklin Roosevelt had a critical goal: a face-to-face sit-down with his allies Joseph Stalin and Winston Churchill. This first-ever meeting of the Big Three in Tehran, Iran, would decide some of the most crucial strategic details of the war. Yet when the Nazis found out about the meeting, their own secret plan took shape—an assassination plot that would’ve changed history.

In a different world, Evie Milton would have accepted her fate, married an aristocrat and become the doyenne of one of England’s finest estates, just like her mother. In a different world, Rose Wiley would have married her fiancé, David, established a modest homestead and brought up a brood of babies, just like her mother. But this isn’t a different world, and these women are not their mothers. Rose dreams of a life filled with more than family and duty to her husband—a life of purpose—and Evie dreams of a life far away from her rarefied existence.

Summer, 1940. Nineteen-year-old Jakob Novis and his quirky younger sister Lizzie share a love of riddles and puzzles. And now they’re living inside of one. The quarrelsome siblings find themselves amidst one of the greatest secrets of World War II—Britain’s eccentric codebreaking factory at Bletchley Park. As Jakob joins Bletchley’s top minds to crack the Nazi's Enigma cipher, fourteen-year-old Lizzie embarks on a mission to solve the mysterious disappearance of their mother.

Bletchley Park looked like any other sprawling country estate. In reality, however, it was the top-secret headquarters of Britain’s Government Code and Cypher School - and the site where Germany’s legendary Enigma code was finally cracked. There, the nation’s most brilliant mathematical minds - including Alan Turing, whose discoveries at Bletchley would fuel the birth of modern computing - toiled alongside debutantes, factory workers, and students on projects of international importance. Until now, little has been revealed about ordinary life at this extraordinary facility.

The Enigma cipher was supposed to be the German's impenetrable defence for its military communications against prying eyes during World War II. All manner of secrets were entrusted to it. When the Allies finally managed to crack the code, it heralded a turning point in the war.

The World War II codebreaking station at Bletchley is well known and its activities documented in detail. Its decryption capabilities were vital to the war effort, significantly aiding the Allied victory. But where did the messages being deciphered come from in the first place? This is the extraordinary untold story of the Y service, a secret even more closely guarded than Bletchley Park. 'Y service' was the code for the chain of wireless intercept stations around Britain and all over the world.

When Stefania Carmichael steps into the mysterious world of Bletchley Park, she immediately finds herself signing the Official Secrets Act. In whispers, she is told that she’s been recruited because of her talent for languages. Before the war ripped Europe apart, Stefania was living in Rome, charming everyone she met, and engaged to the man of her dreams, handsome and brave Matteo. And now everything has changed. With secrets swirling around the building, Stefania finds it hard to know who to trust, until she forms a close bond with two other new recruits.

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.

In 1938, Sarah Baring was enjoying life as a young debutante. Only a few years later, at the height of World War Two, she was working alongside some of the greatest minds of Britain in their code-breaking operations at Bletchley Park. How did she end up in the top-secret world of cyphers and codes?

Alan Mathison Turing. Mathematician, philosopher, codebreaker, a founder of computer science, and the father of Artificial Intelligence, Turing was one of the most original thinkers of the last century - and the man whose work helped create the computer-driven world we now inhabit. But he was also an enigmatic figure, deeply reticent yet also strikingly naive. Turing's openness about his homosexuality at a time when it was an imprisonable offense ultimately led to his untimely death at the age of only 41.
