Marvin Minsky receives the 1969 ACM Turing Award

The A.M. Turing Award is the ACM's annual prize for contributions to computing. In 1969 the association named Marvin Minsky as its recipient^[1]. The citation read: "For his central role in creating, shaping, promoting, and advancing the field of Artificial Intelligence."^[1] The wording honours a career spent building a field, not a single paper or a single machine.

Before the award

Minsky was born in New York City on August 9, 1927^[1]. He took a BA in Mathematics at Harvard College in 1950 and a PhD in Mathematics at Princeton University in 1954^[1]. While at Princeton he built a learning machine out of tubes and motors^[1]: a physical device assembled to learn, rather than only to calculate.

The ideas behind the citation

His 1960 paper "Steps toward Artificial Intelligence" established symbol manipulation as central to attempts to understand intelligence^[1]. The idea is that thinking can be treated as operations performed on symbols — structures that stand for things, relations and rules — so that a machine able to manipulate such structures can be studied as an intelligent system rather than only as a calculator.

In the early 1960s Minsky, together with John McCarthy, founded the MIT Artificial Intelligence Laboratory^[1]. The laboratory gave that research programme an institutional home, a place where the questions raised in the paper could be turned into working programs and machines and where students could be trained to build them.

A date that disagrees with itself

The award carries one small oddity. The ACM lists Minsky as the recipient of the 1969 A.M. Turing Award, while the honours list on the same page records the Turing Award under the year 1970^[1]. Both dates describe the same prize, and the discrepancy is a reminder that the year printed beside an award is not always the year a reader expects: when comparing sources, it is worth checking which year each one means.

Later years

Minsky spent his working life at MIT, where he was Toshiba Professor of Media Arts and Sciences, Emeritus, and Professor of Electrical Engineering and Computer Science, Emeritus^[1]. His other honours include the Japan Prize in 1990 and the IJCAI Research Excellence Award in 1991, and he was past president of the American Association for Artificial Intelligence^[1]. He died in Boston on January 24, 2016^[1].

Why it matters

The citation's four verbs — creating, shaping, promoting, advancing — describe a role that is hard to pin to a single result^[1]. A field needs people who frame its questions, name it, build institutions for it and argue for it in public, and the award recorded that this kind of work counted as a contribution to computing in its own right. It also marked a moment when the questions Minsky had set out in 1960 had become a recognised research area with a laboratory, a vocabulary and a growing body of programs behind it^[1].
