AI milestones in 1972
3 documented milestones from 1972.
MYCIN: A Rule-Based Expert System for Infectious Disease Diagnosis, Developed at Stanford University
Beginning around 1972, Edward Shortliffe at Stanford University developed MYCIN, a rule-based expert system written in Lisp that used approximately 600 if-then rules to diagnose bacterial blood infections and recommend antibiotic treatments adjusted for patient body weight, establishing a widely studied model for clinical decision support.
Prolog Logic Programming Language Created by Alain Colmerauer and Philippe Roussel
In 1972, Alain Colmerauer and Philippe Roussel at the University of Aix-Marseille created Prolog (Programmation en Logique), a declarative programming language grounded in first-order predicate logic, enabling computers to reason over symbolic knowledge without requiring procedural step-by-step instructions.
Smalltalk-72 Developed at Xerox PARC by Alan Kay, Dan Ingalls, and Adele Goldberg
In 1972, Alan Kay and Dan Ingalls at Xerox PARC produced Smalltalk-72, the first working implementation of the Smalltalk language, which embodied Kay's concept of object-oriented programming in which all computation proceeds by objects sending messages to one another.
