Breaking the Code - The Biography of Alan Turing

Computers don't grow on trees, and even though they are ubiquitous today, that wasn't always the case. In fact, they've only been around for less than a hundred years, and although there are certain folks to whom we owe a huge debt of gratitude for laying down the conceptual foundations (the philosopher Leibniz for inventing the binary language system upon which programming depends, for instance, or the enchantress of numbers Ada Lovelace's brilliant insight into the power of computation rather than mere calculation), the individual most directly responsible for modern computation is Alan Turing.

His was a remarkable life, full of genius, insight, inspiration, courage and intellectual creativity. His contributions during World War II (like the fact he broke the Nazi code and was privy to the information sent in secret messages to Hitler and his thugs even before they received it) may be directly responsible for saving hundreds of thousands of lives, and of accelerating the end of the war.

For all of his importance, however, his life was also very tragic. Because of the top-secret nature of his mathematical work during the war, he was never officially recognized. And to add insult to injury, his homosexuality was used to ban him from his own work, to treat him worse than a common criminal, and eventually it led to his suicide. This is his life:
