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 fascinating, improbable true story of Maxwell Knight - the great MI5 spymaster and inspiration for the James Bond character M. Maxwell Knight was perhaps the greatest spymaster in history. He did more than anyone in his era to combat the rising threat of fascism in Britain during World War II, in spite of his own history inside this movement. He was also truly eccentric - a thrice-married jazz aficionado who kept a menagerie of exotic pets - and almost totally unqualified for espionage. Yet he had a gift for turning practically anyone into a fearless secret agent.

After the end of World War II, the race for technological supremacy sped on. Top-secret research into ballistics and computing, begun during the war to aid those on the front lines, continued across the United States as engineers and programmers rushed to complete their confidential assignments. Among them were six pioneering women, tasked with figuring out how to program the world's first general-purpose, programmable, all-electronic computer—better known as the ENIAC. Proving Ground restores these women to their rightful place as technological revolutionaries.

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.

In the late 1930s, legendary financier, philanthropist, and society figure Alfred Lee Loomis gathered the most visionary scientific minds of the 20th century at his state-of-the-art laboratory in Tuxedo Park, New York. He established a top-secret defense laboratory at MIT and personally bankrolled pioneering research into new, high-powered radar detection systems that helped defeat the German Air Force and U-boats. With Ernest Lawrence, he pushed Franklin Delano Roosevelt to fund research in nuclear fission, which led to the development of the atomic bomb.

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.

Few historians end up as historical actors in their own right, but Bernard Lewis has both witnessed and participated in some of the key events of the last century.

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.
