Bletchley Park, Enigma, and GB3RS

Bletchley Park, northwest of London (between Oxford and Cambridge), is one of the best known British sites from WW2. Its fame goes back to the breaking of the legendary Enigma cipher machine and its successor, the Lorenz cipher machine.
In order to perform this work a large effort in the development of early computers took place here. They include the mechanical Bombe for breaking the Enigma, and the valve-based Colossus for breaking the Lorenz.
The Bombe was reconstructed through a 13 year effort that resulted in an Engineering Heritage Award in 2009.

Colossus was the world’s first electronic digital computer that was at all programmable. It was also finally reconstructed in 2007 despite most of the hardware and blueprints being destroyed after WW2.
I visited it with my oldest son who lives in Cambridge, and it was a fascinating place that made me want to learn more about the work done at Bletchley Park and in particular one of the founders of computation, the brilliant Alan Turing, who was treated so badly after the war.

I was also impressed by the National Radio Centre run by the RSGB, callsign GB3RS, with its informative and well laid out exhibition and demonstrations.
They are able to keep it staffed for four days a week based on volunteers, and I really appreciated the hospitality and friendliness of the radio amateurs I met there.
If you ever come to London you should really try to visit this place. It is only a 36 minute train ride from London Euston station.

Bletchley Park was already an impressive site when I visited the place in 2002. The guy that took me there, Keith Canadine, emphasised during the tour that today we all are enjoying freedom because of the efforts that were deployed there. Reading the above will make me go to Bletchley Park once more.
Hi Danny – I think you will see many new things there if you go again. And thanks for the reminder of how the people who worked there contributed to the freedom that Western Europe has had since then.
I’ve seen some video pieces (here in the states) about the site and am very interested to keep learning more about it as I run across articles and links such as yours.
Thanks for making note of a such an historic site.

Timing is everything it seems. Our local PBS station re-ran the Bletchley Park documentary last night.Reviewed the key folks who figured out the ‘key’ for the German code as well as the “first” computer. Great review for a very historic site and time.
