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.
