Alan Mathison Turing (1912 - 1954) was an English mathematician, logician, cryptanalyst and computer scientist. He was highly influential in the development of computer science, providing a formalisation of the concepts of 'algorithm' and 'computation' with the Turing machine, which played a significant role in the creation of the modern computer. Turing is widely considered to be the father of computer science and artificial intelligence.
Today's Google doodle features a Turin machine, a device used to simulate the logic of a computer algorithm and is helpful in explaining the functioning of a CPU. The doodle is interactive and requires users to break a set of six codes and each successful code break adds color to a letter of the greyed out Google logo.
