Computer genius, logician, cryptanalyst and hero of Bletchley Park during WW II, Alan Turing created a code even he could not solve. During the 1940s, Turing became worried about losing his savings, if the German’s invaded Britain. He bought two large silver bars and buried them in the woods near Bletchley Park. Later, returning to dig them up, Alan Turing discovered he was unable to break his own code describing their hiding place. He never did find his hidden silver bars.
