If you stumbled across Alan Turing because of the film “The Imitation Game” starring Benedict Cumberbatch in the lead role, you may be aware of Andrew Hodges’ biography “The Enigma” – the basis of Graham Moore’s Oscar awarded screenplay.
A much deeper inside look at Alan Turing’s work which helped breaking the German enigma code, shortened the Second World War by at least two years and saved millions of lives, you should read the huge book “Alan Turing – His work and impact” by S. Barry Cooper and Jan van Leewen. Yes, there are lots of mathematical theories, even formulas (something very awful for people like me unable to cope with numbers) but the more than 870 pages, accompanied by indexes and bibliographies are worth reading, browsing through essays about and from Alan.
“He was a genius: he was ‘a wonder of the world’.
Bernards Richards about Alan Turing
One essay that strikes me most – besides the ones by Alan himself which offer a look inside the brain of a man a colleague described as “a Wonder of the world” – is the piece “Why Turing cracked the Enigma code and the Germans did not” by Klaus Schmeh. The German computer scientist explains that Germans were unable to bring their cryptographers together to find a possible weakness in the Enigma code itself. Despite the fact that German experts were aware of a possible breach, Britain’s success in breaking Enigma was only revealed in the 1970s when details about the codebreaker’s work at Bletchley Park became public.
“Alan Turing – His work and impact” may not be an easy read. But it is worth every try.
