Introducing the Smalltalk Zoo Share In commemoration of the 40 th anniversary of the release of Smalltalk-80, the Computer History Museum is proud to announce a collaboration with Dan Ingalls to preserve and host the “Smalltalk Zoo.” Below, computer scientist Adele Goldberg explains the vision behind Smalltalk. What is Smalltalk, and what is the Smalltalk Zoo? The Smalltalk Zoo is a collection of historical versions of the revolutionary graphical programming and user environment Smalltalk, originally developed at Xerox PARC, ranging from the 1972 version all the way to the modern “Squeak” version whose development began in 1995. These emulated Smalltalk environments run in your web browser and are hosted by CHM at smalltalkzoo.thechm.org.
