Alan Turing followed the mode of that other Earth-shaking and eccentric English genius, Sir Isaac Newton. That is, he shunted the world into a new epoch.
Born in 1912, the theoretical work Turing conducted when in his mid-20s, specifically discovering mathematical proof that enough simple computations carried out in the right way could solve any solvable problem, is the seed from which our modern software-enabled world grew.
His later code-breaking work during World War II was hidden behind ironclad government secrecy until quite recently. When the true nature of all he’d accomplished became public knowledge (decades after his death in 1954), Turing at once went from an obscure mathematician to a popular hero of the Allied victory in Europe.
Today, Turing is rightly regarded as setting the theoretical stage for computer science and artificial intelligence research.
