When I saw the French navy with bagpipes on a military parade, I was not expecting an absolute banger!

24 May 1941: Mathematician I.J. "Jack" Good joins #BPark Hut 8, helping Alan #Turing with probabilistic analysis of German naval Enigma.

🎧 Part Two is here! Explore the secret world of radio interception in WWII — from chasing shifting frequencies to decoding Morse by hand. 📺 Watch now: youtu.be/oAgHMPfTcGY #BletchleyPark #WWIIHistory #YStations #MorseCode #SignalsIntelligence #RadioInterception

Josephine Baker served as a spy for the French Resistance during WW2. She used her performances to collect intelligence, smuggled messages using invisible ink, and aided refugees at her château. She received the Croix de Guerre and Légion d’honneur for her efforts.

Our Virtual Schlüsselgerät 41 was looking a little naked, so this week, I've been modelling it something to cover it up. This really adds so much to the look of the machine, looking awesome. Still lots to do, so keep following along. Bletchley Park TNMOC CryptoMuseum Three.js

Have you watched part two of our You Tube mini series about Y Stations? In this new video, we dive into the work of the radio intercept operators, the work was incredibly demanding. Operators faced intense pressure, tirelessly capturing enemy messages. In this video, we hear

🎙️Out now - a new episode of The Bletchley Park Podcast: "Dollis Hill Days" Discover the secret wartime work of the Post Office Research Station at Dollis Hill, a key partner in developing codebreaking machines like Colossus and the Bombe. We’re joined by BT archivist

04 Jun 1941: HMS Marsdale captures tanker Gedania and its Enigma codebooks. Germans find out later, and worry that Enigma is compromised.

Mavis Batey (1921–2013) joined Bletchley Park as a codebreaker at 19 years old. Her work was vital to the success of D-Day and played a key role in the defeat of the Italian navy. On the 81st anniversary of the D-Day landings, let's also remember heroines like Mavis Batey.

7 June 1954. Alan Turing died (aged 41). He was a key influence on theoretical computer science and computation with the Turing machine considered a model of a general-purpose computer. He was not fully recognised during his lifetime.

Now we finally get to see how all the messing about in Virtual SG-41 with cogs & cams starts to encipher our letter. A lot of work done in past couple of weeks to get here, this is a fiendishly clever device! TNMOC Bletchley Park CryptoMuseum Three.js

Virtual Colossus Prof. Frank McDonough I had a great book on the NPL and remember reading about Strachey and Turing - Strachey was quickly drawn to intelligent machines and, at the beginning of 1951, joined the National Physical Laboratory, which had just succeeded in building a prototype computer called the Pilot ACE

Lincoln City's new football kit features a coded message to celebrate George Boole who invented Boolean logic & was born in the city. The binary code spells out "We Are Imps" bbc.co.uk/news/articles/…

Adding in a few shadows make all the difference to a simulation. This is made very easy with Three.js which is the JavaScript library I'm using for 3D. The encrypted output is not from a coded sim, it's from the mechanics alone! #VirtualSG41 TNMOC Bletchley Park David Abrutat 🇺🇦

From rowing at Cambridge to running marathons. He even once ran from London to Guildford to visit his mother. 10 things to know about Alan Turing Image credit: Archives Centre, King's College, Cambridge #AlanTuring #TuringLegacy #BletchleyPark

I wonder if I can ask a favour? This Friday, I'm walking in the Milton Keynes "Midnight Moo" to help raise for Willen Hospice who provide free care & support for local people with a life-limiting illness. Even a small amount (if you can) would be amazing! donate.willen-hospice.org.uk/pf/martin-gill…

Time to start on the next part of Virtual Schlüsselgerät 41. Now we have the actual PRNG (pseudo-random number generator) working, the next part is to print! Unlike the M-209, the SG-41 has 2 tapes; one plaintext & one encrypted. Wish me luck! Bletchley Park TNMOC CryptoMuseum

Yes yes! Let's get Bill Tutte's house a blue plaque in Canada! I'm behind this idea all the way .. now who do we have to contact to make it happen
