Cracking the code…

Tuesday 16 July 2019

After a long day at work, there’s no rest for me. My eldest has a driving theory test and I have agreed to be her chauffeur. Upon reaching our location, we are greeted by a sign announcing that ‘Candidates may NOT park at the Centre’. And so it it that I drop her off and then park myself on a dodgy side street, where I try to get on with some work.

Up ahead, a group of youths are knocking on car windows and asking for money. The driver, two cars in front of me hands over some cash and they disappear. The street is quiet after that, nonetheless I decide to keep my window shut and it starts to get very stuffy. Feeling drowsy and struggling to concentrate on my task, I turn to the internet for diversion, and am woken up by Dr Emily Grossman’s article in the Guardian,

Putting Alan Turing on the £50 note is a triumph for British science – and for equality

Hip hip hooray! Back in the Autumn, when the Bank of England launched the public vote on this issue, Turing was my man! There’s the incredible contribution his mathematical brain made to the development of computing, which is mind blowing. And, of course, his legendary code-breaking at Bletchley Park,

You needed exceptional talent, you needed genius at Bletchley and Turing’s was that genius.” ( Asa Briggs )

But with Turing, the human story is equally powerful. Under the Official Secrets Act, much of his work was to remain hidden for a long time, denying him deserved recognition. At the age of 39, he was convicted of ‘gross indecency’ due to a relationship with another man, a judgement that led to the removal of his security clearance. Despite his outstanding contribution to war time intelligence, he was barred from continuing with his cryptographic consultancy for the GCHQ. Far more shockingly, Turing also underwent ‘chemical castration’ treatment, to avoid imprisonment, and died 2 years later, an inquest ruled by suicide.

About 10 years ago, petitions began for his pardon. In 2014, the Queen granted a full pardon and by 2016 the “Alan Turing law” paved the way to retroactively pardon other men too.

We ask the HM Government to grant a pardon to Alan Turing for the conviction of “gross indecency” … Alan Turing was driven to a terrible despair and early death by the nation he’d done so much to save….A pardon can go some way to healing this damage. It may act as an apology to many of the other gay men, not as well-known as Alan Turing, who were subjected to these laws.

So one of the founding fathers of computing, an unsung hero of our war effort and a significant icon for equality. If, like me, you are a mathematician, its is a wonderful privilege to have lived this life seeing the world through the eyes of many of the greatest minds humankind has ever known. And this man is undoubtedly up there at the top, for his immense and lasting contribution to our modern society. I am overjoyed that he has won a place on our £50 note and, as I look closely, the image also features a short piece of binary code. Cocooned as I may be, within the confines of my clammy car, trying to decode this keeps me busy until my eldest emerges triumphant from her theory test…
