The Overlooked Innovator Behind WWII's First Programmable Computer

In World War II, British engineer Tommy Flowers designed and built Colossus, the world’s first programmable electronic computer. Working at Bletchley Park, Flowers’s invention decoded the German Lorenz cipher, giving the Allies access to top-secret Nazi communications and helping secure victory in Europe. This documentary explores the hidden story behind Colossus, the engineering challenges, and how one Post Office engineer transformed the course of computing history — decades before the world even knew his name. Discover how WWII codebreaking, cryptanalysis, and innovation converged to create the first step toward the digital age. Learn why Tommy Flowers’s contribution remained classified for thirty years, and how his work laid the foundations for modern computers, artificial intelligence, and electronic warfare. 🔍 Topics covered: The Lorenz cipher and German high-command encryption The secret operations of Bletchley Park How Colossus Mark I and II changed intelligence work The forgotten role of civilian engineers in the war How secrecy delayed recognition of Britain’s first computer 🟢Welcome to the channel that uncovers the darkest side of history—military war horror stories.
