The Codebreakers – The Story of Secret Writing (ISBN 0-684-83130-9) is a book by David Kahn, published in 1967, comprehensively chronicling the history of cryptography from ancient Egypt to the time of its writing. The United States government attempted to have the book altered before publication, and it succeeded in part.[1]
The Codebreakers is widely regarded as the best account of the history of cryptography up to its publication. William Crowell, the former deputy director of the National Security Agency, was quoted in Newsday magazine: "Before he (Kahn) came along, the best you could do was buy an explanatory book that usually was too technical and terribly dull."[2][3]
The Puzzle Palace (1982), written by James Bamford, gives a history of the writing and publication of The Codebreakers.[4] Kahn, then a journalist, was contracted to write a book on cryptology in 1961. He began writing it part-time, and then he quit his job to work on it full-time.[4] The book was to include information on the NSA and, according to Bamford, the agency attempted to stop its publication. The NSA considered various options, including writing a negative review of Kahn's work to be published in the press to discredit him.[4]
A committee of the United States Intelligence Board concluded that the book was "a possibly valuable support to foreign COMSEC authorities" and recommended "further low-key actions as possible, but short of legal action, to discourage Mr. Kahn or his prospective publishers".[4] Kahn's publisher, Macmillan and Sons, handed over the manuscript to the government for review without Kahn's permission on 4 March 1966.[4] Kahn and Macmillan eventually agreed to remove some material from the manuscript, particularly concerning the relationship between the NSA and its counterpart in the United Kingdom, GCHQ.[4]
The book finishes with a chapter on SETI. Because of the year of its publication, the book did not cover most of the history concerning the breaking of the German Enigma machine, which became public knowledge during the 1970s. Hence, not much was said of Alan Turing. It also did not cover the advent of strong cryptography in the public domain, beginning with the invention of public key cryptography and the specification of the Data Encryption Standard in the mid-1970s. The book was republished in 1996, and this new edition included an additional chapter briefly covering the events since the original publication.
Bradford Hardie III, an American cryptographer during World War II, contributed insider information, German translations from original documents, and intimate real-time operational explanations to The Codebreakers.[5]

The Codebreakers Statue (Welsh: Cerflun Torwyr Cod) is a group statue of the Welsh rugby players Billy Boston, Clive Sullivan, and Gus Risman in Cardiff Bay. Each of the three players began his career in rugby union, before switching to another code of football, rugby league, hence the name "Codebreakers". It is the first statue to depict historical and named Black Welsh men.
David Kahn (February 7, 1930 – January 23, 2024) was an American historian, journalist, and writer. He wrote extensively on the history of cryptography and military intelligence. Kahn's first published book, The Codebreakers – The Story of Secret Writing (1967), has been widely considered to be a definitive account of the history of cryptography.
Bletchley Park is an English country house and estate in Bletchley, Milton Keynes (Buckinghamshire), that became the principal centre of Allied code-breaking during the Second World War. During World War II, the estate housed the Government Code and Cypher School (GC&CS), which regularly penetrated the secret communications of the Axis powers – most importantly the German Enigma and Lorenz ciphers. The GC&CS team of codebreakers included John Tiltman, Dilwyn Knox, Alan Turing, Margaret Rock, Mavis Lever, Harry Golombek, Gordon Welchman, Hugh Alexander, Donald Michie, Bill Tutte and Stuart Milner-Barry. The team at Bletchley Park, 75% women, devised automatic machinery to help with decryption, culminating in the development of Colossus, the world's first programmable digital electronic computer. Codebreaking operations at Bletchley Park ended in 1946 and all information about the wartime operations was classified until the mid-1970s. After the war it had various uses and now houses the Bletchley Park museum.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
