John McCarthy (September 4, 1927 – October 24, 2011) was an American computer scientist and cognitive scientist. McCarthy was one of the founders of the discipline of artificial intelligence.[1] He coined the term "artificial intelligence" (AI), developed the Lisp programming language family, significantly influenced the design of the ALGOL programming language, popularized timesharing, and was very influential in the early development of AI.

McCarthy received many accolades and honors, such as the Turing Award for his contributions to the topic of AI, the United States National Medal of Science, and the Kyoto Prize.

Early life and education

John McCarthy was born in Boston, Massachusetts on September 4, 1927 to an Irish immigrant father and a Lithuanian Jewish immigrant mother,[2] John Patrick and Ida Glatt McCarthy. The family was obliged to relocate frequently during the Great Depression, until McCarthy's father found work as an organizer for the Amalgamated Clothing Workers in Los Angeles, California. His father came from the fishing village of Cromane in County Kerry, Ireland.[3] His mother died in 1957.[4]

McCarthy was exceptionally intelligent, and graduated from Belmont High School two years early.[5] McCarthy was accepted into Caltech in 1944.

McCarthy showed an early aptitude for mathematics; during his teens he taught himself college mathematics by studying the textbooks used at the nearby California Institute of Technology (Caltech). As a result, he was able to skip the first two years of mathematics at Caltech.[6] McCarthy was suspended from Caltech for failure to attend physical education courses[7]; he then served in the US Army and was readmitted, receiving a B.S. in mathematics in 1948.[8]

It was at Caltech that he attended a lecture by John von Neumann that inspired his future endeavors.

McCarthy initially completed graduate studies at Caltech before moving to Princeton University. He received a Ph.D. in mathematics from the institution in 1951 as a student of Solomon Lefschetz.
