Smalltalk - Software Concepts Group, Xerox PARC, led by Alan Kay, early
70s. Took the concepts of class and message from Simula-67 and made them
all-pervasive, the quintessential object-oriented language. Innovations
included the bitmap display, windowing system and use of mouse. Early
versions: Smalltalk-72, Smalltalk-74, Smalltalk-76 (inheritance taken from
Simula, and concurrency), and Smalltalk-78. "The Smalltalk-76 Programming
System Design and Implementation", D.H. Ingalls, 5th POPL, ACM 1978, pp.9-
