Smalltalk is a purely object oriented programming language originally created in the 1970s for educational use in constructionist learning, and later used in business. It was created at Xerox PARC by Learning Research Group scientists including Alan Kay, Dan Ingalls and Adele Goldberg; Smalltalk-80 was the first variant made available outside PARC, shared in 1981 with Tektronix, Hewlett-Packard, Apple and DEC. Its design, in which everything is an object, is the other parent, beside Simula, of the object oriented mainstream.
