Turing Oversold?

However, his greatest impact came probably through his contribution to cracking the Enigma code, used by the German military during the Second World War. He worked with Gordon Welchman at Bletchley Park in the UK. The famous code-breaking Colossus machine, however, was designed by Tommy Flowers (not by Turing). The British cryptographers built on earlier foundational work by Polish mathematicians Marian Rejewski, Jerzy Rozycki and Henryk Zygalski who were the first to break the Enigma code (none of them were even mentioned in the movie). Some say this was decisive for defeating the Third Reich.

Yes, Turing worked on Enigma and the Bombe to automate breaking of the code. However, Colossus wasn't for Engima (it was for Tunny) and Turing didn't work on it. This paragraph seems confused about which is which.

Also, the fact that the Polish who did the original work weren't mentioned in the movie is just one of many things horribly wrong with that movie. It's so bad it shouldn't be considered canon.

I feel the era of great thinkers who single handledly performed disruptive breakthroughs in their field, the Galileos and Newtons, was over with the Einstein-era (and even Einstein also stood in the shoulders of giants).

No one works in isolation any more, and that is not a bad thing. You can subject any relevant figure to a similar analysis and come with the same results, it's absurd to try and come up with someone with such an overwhelming figure like Albert Einstein these days.

But if you need to choose a Founding Father of Computing Science for the general public, I'd say Alan Turing is the best candidate. Scholars will give due credit to Church, Zuse, von Neumann and all the others.

But science fields do need marketing. All children have heroes they look up to. Putting focus on Turing's achievements is merely creating a pop star figure in the mainstream, which I think is a good thing: a smart dude works on a problem that saves World War 2 and now powers your phone and your TikTok app. Once you are actually interested in the field you can work out the nuances and the falsehoods in that claim.

Evaluating earlier work in some field throughout history always leads to a complex graph of achievements, but you cannot put that graph in the name of an annual prize. Do we change "Turing Award" to "Frege-Cantor-Godel-Church-Turing"?

I think this is a joking extrapolation to the real life, and the "author" here is, in best case real life, or as an approximation, historians' position based on evidence.
