Alan Turing’s Enigma Treatise – The Prof’s Book

The Codebreaking Manuscript That Changed History

Known at Bletchley Park simply as "The Prof's Book," this treatise is Alan Turing's own analysis of the Enigma machine and the mathematical techniques used to break its encryption. Written during World War II, this document was classified for decades before being released. Now, Kronecker Wallis presents a meticulously remastered edition that brings Turing's original work to life.

Faithfully Restored, Detail by Detail

Every element of Turing's original typewritten manuscript has been carefully preserved and enhanced:

• Vectorized annotations: All of Turing's handwritten notes, corrections, and margin comments have been digitally traced and reproduced with precision
• Original errors preserved: You will see Turing's own typing mistakes and his handwritten corrections above them, exactly as they appeared in the original
• Complete diagrams: Graphs, tables, technical illustrations, and handwritten mathematical notation faithfully reproduced
• New typography: The typewritten text has been reset in a period-appropriate typeface for improved readability while maintaining the vintage aesthetic
• Vintage style: The publication recreates the look and feel of a classified wartime document

What This Treatise Covers

Turing systematically analyzes the Enigma machine's encryption method: its rotor configurations, plugboard settings, and the mathematical weaknesses he exploited to break the cipher. This is the primary source document for understanding how the Allies cracked the code that the German military believed was unbreakable.

Who This Book Is For

• Computer science students and historians of computing
• Cryptography enthusiasts and cybersecurity professionals
• WWII history collectors and military history readers
• Alan Turing admirers and those inspired by The Imitation Game
• Anyone fascinated by the intersection of mathematics and warfare

Consult the Original

Frequently Asked Questions

Is this the original classified document?

This is a remastered edition of Turing's original typewritten manuscript. The text has been reset in a new typeface for improved readability, but all of Turing's handwritten annotations, corrections, graphs, and tables have been carefully vectorized and faithfully reproduced.

Can I read the handwritten notes clearly?

Yes. All of Turing's handwritten elements have been digitally traced (vectorized) to ensure clarity while preserving the look and character of his original writing. You will see his notes, corrections, and margin comments exactly where he placed them.

Do I need a background in cryptography to understand this book?

Basic knowledge of mathematics helps, but the book is also valuable as a historical document. Even without deep cryptographic expertise, you can appreciate Turing's systematic approach to breaking the Enigma cipher and the historical significance of this wartime manuscript.

How does this relate to the film The Imitation Game?

The Imitation Game (2014) tells the story of Turing's work at Bletchley Park. This treatise is the actual technical document Turing wrote during that period, analyzing the Enigma machine's encryption and the methods used to break it. It is the real-life source behind the film's story.
