Claude Shannon

  • Gerard O’Regan


Claude Shannon was an American mathematician and engineer who made fundamental contributions to computing. He was the first person to see the applicability of Boolean algebra to simplify the design of circuits and telephone routing switches. He showed that Boole’s symbolic logic developed in the nineteenth century provided the perfect mathematical model for switching theory and for the subsequent design of digital circuits and computers.
