The Apple Cambridge lab was started in January 1989 with five developers from Coral (Gary Byers, Jeremy Jones, Andrew Shalit, Richard Mlynarik, and Gail Zacharias). Gary kept working on MCL and the rest of us started designing and implementing the programming language Ralph which became Dylan.

These events led directly to the single best professional experience of my career: working on the experimental bauhaus OS for Newton, which was written in Ralph. The language that Apple Cambridge created for that project remains my favorite programming language to this day.

Of course, these events also led the long-term survival of Coral Common Lisp, first as Macintosh Common Lisp and then as Clozure Common Lisp. In a world without Ralph, Common Lisp remains my favorite programming language that I can still get my hands on.

I owe thanks to Larry, but also to you, Jeremy, and to the rest of the Apple Cambridge team.
