Alan Turing: The Life and Times

The announcement of ‘The Alan Turing institute,’ got me thinking about the legendary genius. Who was he, how did he live his life and what was his legacy?

Anybody who readers the OliverRawlings blog knows that I have a major interest in technology. The way technology changes our world with every new discovery, every practical application, fascinates me. That’s why I’ve long been interested in the life and times of Alan Turing.

His name has entered popular discourse in recent years due to his personal life. Alan Turing was gay in a time where it was illegal to be gay in Britain, and got caught. He was tried, convicted and chemically castrated in 1952. He died from cyanide poisoning at the age of 42 in 1954.

This injustice has led in recent times to a campaign to strike down Turing’s 1952  conviction for homosexuality, based on both the fact that it is now no longer illegal and on the great work he did that changed the world forever. He received a posthumous royal pardon. What was that great work?

Essentially, Turing was a mathematician, logician, cryptanalyst, computer scientist and philosopher. He is perhaps most famous as being a significant contributor to the moderncomputer, through his ‘Turing Machine.’ This means that he’s basically regarded as the father of modern computer science.

The implications of this are enormous. Think about how much the computer has contributed to our world. So much modern technology depends on computer science, that without it, this world would still be stuck in the 19^th Century. Forget smartphones and laptops, we never even would have got the basic computer.

This wasn’t Turing’s only contribution to the world in his lifetime. During the Second World War, he worked at Bletchley Park, the government’s infamous code breaking headquarters. He was vital to the effort to develop the Enigma machine, the device which enabled the allies to understand and manipulate coded Nazi messages.

Again, the magnitude of this work on the modern world is astounding. Have you ever read one of those dystopic novels about how the world went to hell in a hand basket because the Nazi’s won the Second World War?  Yeah… Alan Turing had a large role in stopping that.

Despite his tragic and undeserved end, Alan Turing was a great British hero, and his work influenced modern life in numerous ways. I’m glad that the man himself is being remembered and celebrated as the genius he undoubtedly was.
