John McCarthy Gave Artificial Intelligence Its Name—and Lisp Its Language
John McCarthy transformed artificial intelligence through ideas that still shape modern technology.
John McCarthy helped turn machine intelligence from an intriguing possibility into an academic field. He named it, gave researchers one of its defining languages and kept asking how computers might reason.

Defining milestone
Naming a new discipline
McCarthy used the term “artificial intelligence” in the proposal for the 1956 Dartmouth summer research project. That meeting became a founding moment for a field devoted to making machines perform tasks associated with intelligence.
Lisp made ideas executable
In 1958, he created Lisp, a programming language whose symbolic expressions and recursive style suited early AI research. Its concepts shaped generations of languages and remain influential in computer science.
Computing as a public utility
At Stanford, McCarthy advanced time-sharing, formal reasoning and robotics. He also imagined interactive computing delivered like a utility—an idea that anticipated parts of today’s cloud-computing world.
Why John McCarthy still matters
John McCarthy’s work changed the questions engineers and researchers could ask—and the systems they could build. The clearest thread is an obsession with turning abstract ideas into durable tools.
