The From the home of the co-breakers and the birthplace of modern computing, this is the Bletchley Park podcast.

Welcome to another Bletchley Park podcast Extra.

In this episode we'll bring you another one of the talks from the Codebreaker Legacy event that was held at Bletchley Park.

would call Tommy's greatest achievement, the invention of Colossus, the world's first programmable

electronic digital computer. What I especially like about this talk is the really simple and engaging way

that Jack explains both how the Lorentz, or Tunney, as it was known by the codebreakers, worked

and how codebreakers such as Bill Turing and Max Newman, with the help of engineers such as

Tommy, finally broke into Hitler's most secret code.

Tommy Flowers is one of my greatest heroes,

so it's an absolute pleasure to be talking about him here today.

Flowers' most significant contribution, of course, was to design and build the world's first large-scale electronic computer, Colossus.

And here is the man himself.

This photograph of Flowers was given to me by Fleur's son, Kenneth. And when

he handed it to me, it was in the form of a old-fashioned black and white print. And it had obviously

been screwed up into a ball at some point in its existence, presumably by a young child,
