Seminar with Alan Kay on Object Oriented Programming (VPRI 0246)
Yoshiki Ohshima (大島芳樹)
A long recorded seminar in which Alan Kay discusses object-oriented programming, probably from the mid-1980s. He covers the original idea of objects, messaging and the work done at Xerox.
HN points to it as primary-source evidence of what Kay meant by objects, which resembled services and message passing rather than modern class-based OOP.
