Smalltalk is an object-oriented programming language, developed by a team at the Xerox Palo Alto Research Center which included Alan Kay, Dan Ingalls and Adele Goldberg. In Smalltalk everything is an object, and computation is done by sending messages between objects, and the language runs in an environment that can be changed while the program runs. It was designed to be used by children and others to learn programming and to create simulations, as part of Kay's Dynabook vision of personal computing. The Smalltalk environment also pioneered the graphical user interface, with windows and menus. It strongly influenced later languages such as Objective-C, Java and Ruby.
