George Boole


(1815–64) Mathematician who devised a method by which logical reasoning could be expressed in mathematical form, the resulting method being generally known as Boolean algebra. The simplest binary version of this algebra became the language of computers. His ideas were most fully expressed in An Investigation of the Laws of Thought, on which are founded the mathematical theories of logic and probabilities (1854).
