Alan Turing saved millions of lives. But Bletchley Park wasn’t the only major code-breaking operation during World War II. Down under, there was Central Bureau. Central Bureau — Australia’s own large and sophisticated intelligence network, built from scratch. It was this group of mathematicians, code-breakers, and radio experts who intercepted the travel plans of the architect of the Pearl Harbor attack, Admiral Yamamoto, leading to his ambush and death. Australian signals intelligence also played a vital role in the battles of the Coral Sea, Milne Bay, Hollandia, and many others. General Douglas MacArthur, the supreme commander of the local Allied forces, went so far as to insist that the men of Central Bureau accompany him on his counter-attack in the Pacific. After the war, the US sought to give these non-combatants the highest awards possible — honours that were suppressed by the Australian government in their need for secrecy. A groundbreaking work of military history, The Secret Code-Breakers of Central Bureau gives these talented and dedicated individuals their due at last. It is a rich account of the shadowy side of military strength and of the men and women whose work was, in the words of the US navy, of ‘immeasurable importance in the successful prosecution’ of the Pacific War.

Have you ever wished that you could do something heroic to help your country? When Alan Turing was a boy, he was fascinated by math and science. Later, Turing's math skills would help Great Britain win World War II. Turing's parents and teachers thought he'd be better off dropping math in favor of more gentlemanly studies, such as literature and Latin. But he stuck with it, and by the start of World War II in 1939, he was ready to take on the biggest challenge his country faced: Nazi Germany. Turing put his advanced knowledge of math to work decoding secret German messages. His ideas not only helped Great Britain turn the tide of the war—they provided the foundation upon which much of modern computing and artificial intelligence is based.

An exploration of how codes—both cipher and aesthetic—have come to exist in history from Pythagoras through the Knights Templar to Turing and more. Did the Masons encode messages in walls—and even in the street plan of Washington, D.C.? Does the Hebrew Bible conceal hidden mysteries? Ingenious methods for encoding secrets have taken many amazing turns through the ages, from the military signals the Romans flashed from hilltop to hilltop, to the computer codes that guard your cash at the ATM. Pierre Berloquin, one of France’s leading puzzle book authors, takes you on a tour of them all in a book full of astonishing historical insights. With more than 150 brain-teasing problems for readers to solve for themselves, this is a journey beyond the gee-whiz and deep into the how-to of codes, ciphers, and other secret communication systems.

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.
