Common Lisp vs. Smalltalk

Which Smalltalk got the basics from Lisp anyway, like the image-based development, in-core editing, interactive debugging, ... Core implementors came from PDP-1 LISP (implemented by L Peter Deutsch in 1962, who implemented much of the low-level of Smalltalk) and then BBN Lisp.

"Deutsch moved to Xerox PARC, where he worked on the Interlisp system and on the Smalltalk virtual machine, helping to invent the technique of just-in-time compilation."

Here a Interlisp manual from 1972: http://bitsavers.informatik.uni-stuttgart.de/pdf/bbn/tenex/T...

BBN Lisp was then developed as Interlisp at Xerox PARC, side by side with Smalltalk. Interlisp-D then run on the same hardware as the Smalltalk system, but as its own OS/IDE/Window system...
