The "Early Lisp History" paper at
http://www8.informatik.uni-erlangen.de/html/lisp/histlit1.html definitely
shows otherwise: Lisp was designed from the beginning as a programming
language, and was specific to the IBM 704: in addition to car and cdr,
there were also cpr, csr, cir, and ctr selectors (and cwr to select the
whole word) and corresponding setters, and two relatives of cons, consw
(whole word) and consls (sublist).
