John McCarthy, the American mathematician known universally as the father of Artificial Intelligence, died last Monday at his home in Palo Alto. He was 84.
WEEKEND EDITION's Math Guy, Keith Devlin, knew McCarthy and has this remembrance.
KEITH DEVLIN, BYLINE: I first got to know John McCarthy when I arrived at Stanford as a visiting professor in 1987. He was 60 years old at that time, with a towering and, to me, somewhat daunting, reputation.
