The Lisa had the Application Toolkit, which was a shared library written in Clascal (predecessor to Object Pascal) that had all of the basic behaviors of an application.

Then the Macintosh had its function library, called the Toolbox. That's where a great many people heard the term. (The Mac didn't have a framework, though it did get MacApp later - which was similar in design to the Application Toolkit and originally written in Object Pascal.)
