===Clascal and Apple's early Object Pascal===

Object Pascal is an extension of the Pascal language that was developed at [[Apple Computer]] by a team led by [[Larry Tesler]] in consultation with [[Niklaus Wirth]], the inventor of Pascal.<ref>{{cite journal |last1=Tesler |first1=Larry |title=Object Pascal Report |journal=Structured Language World |date=1985 |volume=9 |issue=3 |pages=10–7}}</ref>. It is descended from an earlier object-oriented version of Pascal named [[Clascal]], which was available on the [[Apple Lisa|Lisa]] computer.

Object Pascal was needed to support [[MacApp]], an expandable Macintosh application framework that would now be termed a [[class library]]. Object Pascal extensions, and MacApp, were developed by Barry Haynes, Ken Doyle, and Larry Rosenstein, and were tested by Dan Allen. Larry Tesler oversaw the project, which began very early in 1985 and became a product in 1986.
