Washington Post article: Stanford professor John McCarthy, father of artificial intelligence, dies in Calif. at age 84 - The Washington Post
I've been wondering who the third one to die would be- first Jobs, then Ritchie, now McCarthy. McCarthy was a pioneer and an innovator in the computing and artificial intelligence world, and he invented lisp. He coined the term "artificial intelligence", and the impact of his contributions will continue to be felt as more advanced AI is built on the foundation that he created.
I've been working in lisp for my AI class, and this news makes all my frustrations seem a little more worthwhile.
