Recently, the Computer History Museum has uploaded on its YouTube channel a lecture called Origins of the Apple human interface, delivered by Larry Tesler and Chris Espinosa. The lecture was held at the Computer History Museum in Mountain View, California, on October 28, 1997.
Being extremely interested in the subject myself, and seeing how apparently little thought is being given today to the subject, I wanted to quote a few selected excerpts from the talk, just to show what kind of hard work creating a user interface was back in the day when the Apple Lisa was being developed. It turns out that isolating this or that bit was futile, as the whole talk is made up of such cohesive, engrossing discourse. So I chose to transcribe it almost entirely, and add a few personal remarks here and there. You can read the full annotated transcription on my main website.
