From abstract: "Smalltalk-80, the language from which Squeak is derived, traces its roots to the famous beanbag chair culture of Xerox PARC in the 1970s. Developed by a team headed by Dan Ingalls, Smalltalk was to be the supporting software environment for Alan Kay's visionary portable and networked Dynabook computer -- a concept that remains compelling today. Though the original Dynabook never came into being, Smalltalk took root and continued on. Ingalls tells the story of how the forward-looking Smalltalk concepts and capabilities have evolved into a modern environment called Squeak that could still be... the supporting software environment for the Dynabook.
