Marvin Minsky

Marvin Lee Minsky (August 9, 1927 – January 24, 2016) was an American mathematician who conducted research in the cognitive and computer science aspects of artificial intelligence (AI). After three years as a Junior Fellow of the Harvard Society of Fellows, Minsky joined the faculty at the Massachusetts Institute of Technology (MIT) in 1958 and spent the rest of his career at that institution. There, he co-founded MIT's AI laboratory, among other initiatives, and wrote extensively about AI and philosophy. Minsky, Claude Shannon, Nathaniel Rochester, and John McCarthy have been called the "fathers of AI" due to their participation in the Dartmouth workshop. At the time he was made emeritus, Minsky was the Toshiba Professor of Media Art & Sciences at MIT. Minsky received many accolades and honors for his work, including the ACM Turing Award in 1969, the Golden Plate Award of the American Academy of Achievement in 1982, the Japan Prize in 1990, the Benjamin Franklin Medal in 2001, and of the past-present-future trio of Dan David Prizes in 2014, the "Future"-oriented prize for "Artificial Intelligence, the Digital Mind". He was elected to the U.S. National Academy of Sciences in 1973 and the U.S. National Academy of Engineering in 1989, and was inducted into IEEE Intelligent Systems' AI Hall of Fame for contributions to AI and intelligent systems in 2011.

Early life and education Marvin Lee Minsky was born on August 9, 1927, into a Jewish family in New York City. His mother was Fannie (Reiser), a Zionist activist, and his father was Henry, an eye surgeon. Minsky attended the Ethical Culture Fieldston School and the Bronx High School of Science. He later attended Phillips Academy in Andover, Massachusetts. He served in the U.S. Navy from 1944 to 1945 before returning to his education and earning a A.B. in mathematics from Harvard University (1950) and a Ph.D. in mathematics from Princeton University (1954). His doctoral dissertation was titled "Theory of neural-analog reinforcement systems and its application to the brain-model problem".

Career Minsky began his academic career as a Junior Fellow of the Harvard Society of Fellows from 1954 to 1957. He joined the MIT faculty in 1958 and remained there until his death. He joined the staff at MIT Lincoln Laboratory in 1958; a year later, he and John McCarthy initiated what was, as of 2003, named the MIT Computer Science and Artificial Intelligence Laboratory. At the time of his death, Minsky was the Toshiba Professor of Media Arts and Sciences as well as professor of electrical engineering and computer science at MIT.

Contributions in computer science

Minsky's inventions include the first head-mounted graphical display (1963) and the confocal microscope (1957, a predecessor to today's widely used confocal laser scanning microscope). With Seymour Papert, he developed the first Logo programming language-driven "turtle robot". In 1951, Minsky built SNARC, which is often considered the first artificial neural network. In 1962, he worked on small universal Turing machines and published his well-known 7-state, 4-symbol machine. Minsky and Papert's book Perceptrons attacked the work of Frank Rosenblatt on Perceptrons and became the foundational work in the analysis of artificial neural networks. The book is controversial, as some claim it greatly discouraged research on neural networks in the 1970s and contributed to the so-called "AI winter". Minsky also developed several other AI models. His paper "A Framework for Representing Knowledge" created a new paradigm in knowledge representation. Perceptrons is now viewed as of more historical than practical interest, but his theory of frames was in wide use as of 1975.

In the early 1970s, at the MIT Artificial Intelligence Lab, Minsky and Papert began to develop what came to be known as the Society of Mind theory. The theory describes intelligence as the possible product of the interaction of non-intelligent parts. Minsky said that ideas for the theory came from his work in trying to create a machine that uses a robotic arm, a videocamera, and a computer to build with children's blocks. In 1986, he published The Society of Mind, a comprehensive book on the theory that—unlike most of his previously published work—was written for the general public. In 2006, Minsky published The Emotion Machine, a book that critiques many popular theories of how the human mind works, and suggests alternative theories, often replacing simple ideas with more complex ones.

Miscellaneous interests Minsky examined the possibility that extraterrestrial life may think like humans, thus permitting communication. Minsky invented a "gravity machine" that rings a bell if the gravitational constant changes, a theoretical possibility not expected to occur in the foreseeable future.

Role in popular culture Minsky was an adviser to Stanley Kubrick on his movie 2001: A Space Odyssey; one of the movie's characters, Victor Kaminski, was named in Minsky's honor. Arthur C. Clarke's novel of the same name explicitly mentions Minsky. In it, he achieves a crucial breakthrough in artificial intelligence in the then-future 1980s, paving the way for HAL 9000 in the early 21st century:

In the 1980s, Minsky and Good had shown how artificial neural networks could be generated automatically—self replicated—in accordance with any arbitrary learning program. Artificial brains could be grown by a process strikingly analogous to the development of a human brain. In any given case, the precise details would never be known, and even if they were, they would be millions of times too complex for human understanding.

While working at Bell Labs in 1952, Minsky proposed a design for a useless machine he called the "ultimate machine". When switched on, a device emerges from it to switch it back off. Claude Shannon, Minsky's mentor at the time, built the first working prototype. After seeing it, Arthur C. Clarke commented "There is something unspeakably sinister about a machine that does nothing—absolutely nothing—except switch itself off". The design regained popularity in the 2010s on the internet. The Fargo episode "The Law of Non-Contradiction" included a useless box and an android named Minsky.
