 From the _History of Programming Languages_, edited by Wexelblat,    (02)

p. 174, McCarthy wrote:  "During the meeting [at Dartmouth in 1956],
Newell, Shaw, and Simon described IPL 2, a list processing language
for RAND Corporation's JOHNNIAC computer."    (03)

At that meeting, plans for a new programming language were being
discussed, and Nat Rochester from IBM made sure that an IBM 704
would be available to run it.    (04)

That same book says that the specifications for Algol 58 weren't
actually implemented until later by various groups that adopted
different names for their versions -- MAD, JOVIAL, NELLIAC.    (05)

The Algol 58 spec's didn't require recursion, nor did they
prohibit recursion.  The Algol 60 spec's did require recursion.    (06)
