John McCarthy

Definition

John McCarthy was an American computer scientist and cognitive scientist, known as one of the founders of artificial intelligence (AI). He coined the term 'artificial intelligence' in 1955 and organized the seminal Dartmouth Conference in 1956, which is considered the birthplace of AI as a field. His work not only laid the groundwork for AI but also contributed significantly to computer science through his development of the LISP programming language.
