Dr Black visited Brazil recently and toured the country lecturing on Bletchley Park and Alan Turing - 2012 being the one hundredth anniversary of the birth of Turing.
The estate of Bletchley Park can be found, enjoying regal respite, on lavish greens in Buckinghamshire. To the casual observer, there is nothing at all captivating about the site. But to the historian, or, fortunately, many a charming survivor of the old British Empire, this extensive manor is not merely a ramshackle corporation, it is the soul of our nation, hollowed ground, and the very embodiment of that uniquely British spirit, of resilience.
