PERSON
George Boole
The self-taught English mathematician who reduced the operations of human reasoning to an algebra of zeros and ones—believing he had described the mind, producing instead the blueprint of the digital computer—and whose masterwork, The Laws of Thought, bound logic and probability into a single science of reasoning that AI has spent a century trying to reunify.
George Boole was born in Lincoln in 1815 to a shoemaker with a passion for optical instruments, taught himself mathematics from borrowed texts, ran his own school to support his family, and won the Royal Society's Royal Medal in 1844 before holding any university degree. In 1854 he published
An Investigation of the Laws of Thought, the most consequential book in the history of computing he did not know he was writing. He believed he was describing the human mind; he was describing the machine. His algebra—treating logical operations as arithmetic over the values 0 and 1, with the law
x² =
x forcing every meaningful term toward exactly two states—sat as an elegant abstraction for seventy years until a twenty-one-year-old MIT student named
Claude Shannon recognized in 1937 that Boole's two-valued algebra was the exact mathematics
