Cracking the Lorenz Cipher (Preston)

Tutte, Flowers and the Birth of Colossus

About

This talk tells the story of how engineers and mathematicians at Bletchley Park overcame the formidable Lorenz cipher. You’ll discover how Bill Tutte deduced the machine design, how Max Newman and Tommy Flowers turned a problem into an engineering challenge, and how their creation – Colossus, the first programmable electronic computer – transformed codebreaking. The session offers insights into the blend of mathematics, ingenuity, and technology that not only shortened the war but also shaped the dawn of computing.
