Clascal
From Lazarus wiki
Clascal was the first working prototype of Object Pascal. Developed in 1983 by the Personal Office Systems (POS) division (later renamed The Lisa Division, still later The 32-Bit Systems Division) of Apple Computer, it was the first truly object-oriented version of Pascal.
Clascal was an extension of Lisa Pascal and strongly inspired by Xerox PARC's release of Smalltalk-80 and also by the Modula language. It laid in turn the foundation for the development of Apple's Object Pascal, later referred to as Mac Pascal.
