An object-oriented operating system and programming language developed at Xerox Corporation’s Palo Alto Research Center. Smalltalk was the first object-oriented programming language (Simula was the very first). Although it never achieved the commercial success of other languages such as C++ and Java, Smalltalk is considered by many to be the only true object-oriented programming environment, and the one against which all others must be compared.
