McCarthy coined the term “Artificial Intelligence” in 1955, with his desire for an algebraic list processing language for AI taking shape in the form of Lisp in 1958. Following this, McCarthy developed garbage collection for Lisp in 1959. McCarthy proposed computer time-sharing in a speech in 1961.

He was the winner of the Turing Award, Benjamin Franklin Medal and was also inducted into the IEEE’s Intelligent Systems Hall of Fame in August.

The news comes on the back of fellow Turing Award winner, C creator and Unix co-creator Dennis Ritchie who passed away earlier this month.
