Robert Rosen

Robert Rosen (June 27, 1934 – December 28, 1998) was an American theoretical biologist and Professor of Biophysics at Dalhousie University... His year-long sabbatical in 1970 as a visiting fellow at Robert Hutchins' Center for the Study of Democratic Institutions in Santa Barbara, California was seminal, leading to the conception and development of what he later called Anticipatory Systems Theory, itself a corollary of his larger theoretical work on relational complexity. https://en.wikipedia.org/wiki/Robert_Rosen_(biologist)

Complexity Theory person - A system is simple if all its models are simulable. A system that is not simple, and that accordingly must have a nonsimulable model, is complex.
