August 1996
The Computer Recreations column of Scientific American for March 1985 related a somewhat garbled version of the ANIMAL saga a little more than ten years after the events upon which it was based. David D. Clark of the Laboratory for Computer Science at the Massachusetts Institute of Technology recounted the story in a letter to columnist A. K. Dewdney. Already, the ANIMAL story had begun to mutate into an "urban legend" of computerdom - moving through space and time, recalled by a "friend of a friend", and accreting additional details with every telling.
