Alan Turing: The Genius Who Founded Computing and Artificial Intelligence

Alan Turing was one of the greatest geniuses of the 20th century.

Like all geniuses, he lived briefly — just 41 years — yet his contributions shaped the course of all humanity.

Alan Turing’s Mathematical Legacy: The Foundation of Computing

In 1936, at the age of 24, Turing published a paper titled “On Computable Numbers,” the essence of which was the concept of a universal computing machine — the Turing Machine. Using only zeros and ones, this theoretical device could solve any problem (or determine that a problem was unsolvable). That paper laid the intellectual foundation for every computer ever built.

Breaking Enigma: How Turing Helped Win World War II

Turing played a decisive role for the Allies in World War II by cracking the Enigma — the device Germany used to encrypt all military communications. The British credit him with saving millions of lives. You may have seen a version of this story in the film starring Benedict Cumberbatch; there is more than a grain of truth in it.

The Athlete Behind the Alan Turing Legacy

Few people know that Turing nearly competed in the 1948 Olympic Games. He finished 5th in a qualifying marathon, but a leg injury prevented him from making it to the Olympics. His marathon time that day was 2:46:03.

Alan Turing’s Legacy in Artificial Intelligence

In 1950, Turing published “Computing Machinery and Intelligence,” where he tackled the question: Can machines think? Rather than debating the philosophy, he proposed a practical alternative — the Imitation Game. If a machine could behave indistinguishably from a human, perhaps that was answer enough. This became known as the Turing Test.

The idea has never lost its relevance. Every time someone tests ChatGPT or a similar AI tool and tries to gauge how “human” it feels, they are, in essence, running Turing’s experiment — decades after he first described it.

What Came Next

But there is another fascinating side to Alan Turing — one that is less often discussed. His story did not end with mathematics and code-breaking, and that chapter is just as remarkable as everything that came before it.
