Welcome to this Bletchley Park Intelligence Insight.

In this episode, we're going to take you back to 2017.

That year was the centenary of a relatively little-known genius

who went straight from studying

mathematics at Cambridge to code breaking for the government code and cyphers school. The crucial role

that Bill Tut played in the attack on the system that Hitler and his high command used, Lorenz,

not only broke it, but also helped pave the way for the creation of the world's first

large-scale digital computer,

colossus. Bill finally now receives the recognition he richly deserved. In 2017, there was a BBC

documentary about him. At Bletchley Park, we opened a major exhibition about him, and on the actual

day of his centenary, we held a symposium

of talks about his life and work. When we originally put that episode out, we could only really

include sort of five minute, ten minute highlights from each of the talks, just due to the number

of people who'd spoken. So I'm really pleased that we can bring you the entire talk and question

and answer session from that day, from GCHQ's shortly to retire departmental historian Tony Comer.

Tony decided in his talk that he'd look at some of the fundamental changes that had happened at GCNCS that basically allowed Bill to carry out his breathtaking achievements.

After the talk, we've decided to include the interview we recorded last year with Tony at the National Arboretum.

It was a nice opportunity to look back at his career and also to exclusively introduce his replacement.

But before that, we'll go back to the Built Tutte's symposium in 2017, where Catherine Lynch,

court at returning before his talk.
