Norbert Wiener
The author of Cybernetics: or the Control and Communication in the Animal and the Machine
[ISBN 026273009X],
The Human Use of Human Beings: Cybernetics and Society [ISBN 0306803208], and many other seminal works in the computer industry. I believe he invented the term 'cybernetics', derived from the Greek 'gubernetes', a governor (?).
(Hey, I'm surprised he didn't have a page before!)
