John McCarthy (born September 4, 1927, in Boston, Massachusetts), is an American computer scientist and cognitive scientist who received the Turing Award in 1971 for his major contributions to the field of Artificial Intelligence (AI). He was responsible for the coining of the term "Artificial Intelligence" in his 1955 proposal for the 1956 Dartmouth Conference and is the inventor of the Lisp programming language.

[edit] Life

John McCarthy was born in Boston on September 4, 1927 to two immigrants, John Patrick and Ida Glatt McCarthy. The family was forced to move frequently during the depression, until McCarthy's father found work as an organizer for the Amalgamated Clothing Workers in Los Angeles, California. McCarthy showed an early aptitude for mathematics; in his teens he taught himself mathematics by studying the textbooks used at the nearby California Institute of Technology (Caltech). As a result, when he was accepted into Caltech the following year, he was able to skip the first two years of mathematics.[2]

Receiving a B.S. in Mathematics in 1948, McCarthy initially continued his studies at Caltech. He received a Ph.D. in Mathematics from Princeton University in 1951 under Solomon Lefschetz. After short-term appointments at Princeton, Stanford, Dartmouth, and MIT, he became a full professor at Stanford in 1962, where he remained until his retirement at the end of 2000. He is now a Professor Emeritus.

[edit] Work

McCarthy championed mathematical logic for Artificial Intelligence. In 1958, he proposed the advice taker, which inspired later work on question-answering and logic programming. Based on the Lambda Calculus, Lisp rapidly became the programming language of choice for AI applications after its publication in 1960 [3]. He helped to motivate the creation of Project MAC at MIT, but left MIT for Stanford University in 1962, where he helped set up the Stanford AI Laboratory, for many years a friendly rival to Project MAC.

In 1961, he was the first to publicly suggest (in a speech given to celebrate MIT's centennial) that computer time-sharing technology might lead to a future in which computing power and even specific applications could be sold through the utility business model (like water or electricity). This idea of a computer or information utility was very popular in the late 1960s, but faded by the mid-1970s as it became clear that the hardware, software and telecommunications technologies of the time were simply not ready. However, since 2000, the idea has resurfaced in new forms. See application service provider.

From 1978 to 1986, McCarthy developed the circumscription method of nonmonotonic reasoning.

John McCarthy often comments on world affairs on the Usenet forums. Some of his ideas can be found in his sustainability web page, which is "aimed at showing that human material progress is desirable and sustainable".
