Watch Craig Bauer discuss the Zodiac Killer’s cipher on HISTORY’s new miniseries The Hunt for the Zodiac Killer In 1953, a man was found dead from cyanide poisoning near the Philadelphia airport with a picture of a Nazi aircraft in his wallet. Taped to his abdomen was an enciphered message. In 1912, a book dealer named Wilfrid Voynich came into possession of an illuminated cipher manuscript once belonging to Emperor Rudolf II, who was obsessed with alchemy and the occult. Wartime codebreakers tried—and failed—to unlock the book's secrets, and it remains an enigma to this day. In this lively and entertaining book, Craig Bauer examines these and other vexing ciphers yet to be cracked. Some may reveal the identity of a spy or serial killer, provide the location of buried treasure, or expose a secret society—while others may be elaborate hoaxes. Unsolved! begins by explaining the basics of cryptology, and then explores the history behind an array of unsolved ciphers. It looks at ancient ciphers, ciphers created by artists and composers, ciphers left by killers and victims, Cold War ciphers, and many others. Some are infamous, like the ciphers in the Zodiac letters, while others were created purely as intellectual challenges by figures such as Nobel Prize–winning physicist Richard P. Feynman. Bauer lays out the evidence surrounding each cipher, describes the efforts of geniuses and eccentrics—in some cases both—to decipher it, and invites readers to try their hand at puzzles that have stymied so many others. Unsolved! takes readers from the ancient world to the digital age, providing an amazing tour of many of history's greatest unsolved ciphers.

Presents new facts and suppositions on the Beale treasure story.

First discovered in a Hungarian library in 1838, the Rohonc Codex keeps privileged company with some of the most famous unsolved writing systems in the world, notably the Voynich manuscript, the Phaistos Disk, and Linear A. Written entirely in cipher, this 400-year-old, 450-page-long, richly illustrated manuscript initially gained considerable attention but was later dismissed as an apparent forgery. No serious scholar would study it again until the turn of the twenty-first century. This engaging narrative follows historian Benedek Láng’s search to uncover the truth about this thoroughly mysterious book that has puzzled dozens of codebreakers. Láng surveys the fascinating theories associated with the Codex and discusses possible interpretations of the manuscript as a biblical commentary, an apocryphal gospel, or a secret book written for and by a sect. He provides an overview of the secret writing systems known in early modern times and an account of the numerous efforts to create an artificial language or to find a long-lost perfect tongue—endeavors that were especially popular at the time the Codex was made. Lastly, he tests several codebreaking methods in order to decipher the Codex, finally pointing to a possible solution to the enigma of its content and language system. Engagingly written, academically grounded, and thoroughly compelling, The Rohonc Code will appeal to historians, scholars, and lay readers interested in mysteries, codes, and ciphers.

During the 1920s Herbert O. Yardley was chief of the first peacetime cryptanalytic organization in the United States, the ancestor of today's National Security Agency. Funded by the U.S. Army and the Department of State and working out of New York, his small and highly secret unit succeeded in breaking the diplomatic codes of several nations, including Japan. The decrypts played a critical role in U.S. diplomacy. Despite its extraordinary successes, the Black Chamber, as it came to known, was disbanded in 1929. President Hoover's new Secretary of State Henry L. Stimson refused to continue its funding with the now-famous comment, "Gentlemen do not read other people's mail." In 1931 a disappointed Yardley caused a sensation when he published this book and revealed to the world exactly what his agency had done with the secret and illegal cooperation of nearly the entire American cable industry. These revelations and Yardley's right to publish them set into motion a conflict that continues to this day: the right to freedom of expression versus national security. In addition to offering an exposé on post-World War I cryptology, the book is filled with exciting stories and personalities.
