"The Roots of LISP" include Herbert Simon and Allen Newell too. They co-invented the linked list (once called "NSS memory") in the mid 1950s, setting the stage for LISP and earning them a Turing award (McCarthy got his own). They were founders of AI and implemented some really neat software like the General Problem Solver. See Simon's "The Sciences of the Artificial" or his Nobel prize lecture, and "Unified Theories of Cognition" by Newell.
