Boolean operators are named for George Boole (1815-1864), who was a mathematician, logician and philosopher whose legacy of Boolean algebra and symbolic logic is credited with laying the foundations for the information age. According to GeorgeBoole.com, a University College Cork website dedicated to him, "his legacy surrounds us everywhere. His pivotal advances in mathematics, logic and probability provided the essential groundwork for modern mathematics, microelectronic engineering and computer science."
