Carl E. Hewitt is an Associate Professor (Emeritus) in the Electrical Engineering and Computer Science department at the Massachusetts Institute of Technology (MIT). Hewitt obtained his PhD in mathematics at MIT in 1971, under the supervision of Seymour Papert, Marvin Minsky, and Mike Paterson. He is known for his design of Planner , which was the first Artificial Intelligence programming language based on procedural plans that were invoked using pattern-directed invocation from assertions and goals. He is also known for his work on the Actor model of computation, which influenced the development of the Scheme programming language and the π calculus, and served as an inspiration for several other programming languages.
Biography
Work on Planner
Hewitt's work on Planner introduced the notion of the "procedural embedding of knowledge", which was an alternative to the logical approach to knowledge encoding for artificial intelligence pioneered by John McCarthy. A subset of Planner called Micro Planner was implemented by Gerry Sussman, Eugene Charniak and Terry Winograd. It was used in Winograd's famous SHRDLU program, and Eugene Charniak's natural language story understanding work.
Work on the Actor Model
Hewitt's work on the Actor model of computation has spanned over 30 years. The first work on the Actor model was published in a 1973 paper authored by Hewitt, Peter Bishop, and Richard Steiger. Since then, Hewitt has continued to work on the development of the Actor model, publishing new results on Actor model semantics as recently as 2006.
MIT career
Hewitt was inducted into MIT's Quarter Century Club, marking 25 years of employment at MIT, in March of 1996. He retired from the faculty of the MIT Department of Electrical Engineering and Computer Science during the 1999-2000 school year. During his time at MIT, Hewitt supervised the studies of a number of doctoral students, including Dr. Russell Atkinson, Dr. Gerald Barber, Dr. Peter Bishop, Professor William Clinger, Dr. Peter de Jong, Dr. Irene Greif, Dr. Kenneth Kahn, and Professor Akinori Yonezawa.
Awards
From September 1989 to August 1990, Hewitt was the IBM Chair Visiting Professor in the Department of Computer Science at Keio University in Japan.
