Smalltalk was developed in the Learning Research Group (LRG) at Xerox's Palo Alto Research Center back in the early 1970. The group was led by Alan Kay who worked on a vision he called "Dynabook" - the computer could be used creatively like a dynamic book. even by children. Their explorations led them to develop not only the prescient vision of notebook computing (the Dynabook), but also to the Smalltalk object-oriented programming language. The first Smalltalk programming system (called Smalltalk-72) ran on a Xerox Alto and was designed to support Alan Kay's new programming paradigm called object-oriented programming.
