The Science of Secrecy: How Cryptography Defined World War I

In this documentary, we explore the evolution of signals intelligence (SIGINT) during the First World War, a conflict that marked the transition from classical codes to modern mathematical ciphers. While the war is often defined by its physical battlefields, a silent struggle for information was waged through the electromagnetic spectrum, fundamentally altering global geopolitics. We examine the technological shift necessitated by the cutting of German undersea cables and the subsequent rise of wireless telegraphy. This video details the rigorous scientific methods used by elite units like Britain’s "Room 40" and France’s "Bureau du Chiffre." You will learn about the complex mechanics of the ADFGVX cipher and how Captain Georges Painvin used frequency analysis to halt the German Spring Offensive of 1918. Furthermore, we analyze the interception and decryption of the Zimmermann Telegram, a landmark event in cryptanalysis that served as the catalyst for the United States' entry into the war. By understanding these historical breakthroughs, we gain insight into the foundations of modern cybersecurity and the birth of the computer. Join us as we uncover the mathematicians and linguists who turned the tide of the Great War through the power of the algorithm.
