H EMOGLOBIN KOLN (Hb K#{246}ln) is characterized by a point mutation in its chains, in which the f198 valine is replaced by the bulkier methionine residue.1 This substitution destabilizes the hemoglobin’s T state and increases its oxygen affinity, while at the same time loosening the heme pocket and making Hb K#{246}ln subject to heme loss and to the precipitation of granular deposits, known as...

Reproduced below, with a few small edits, is a paper I wrote in 1979 for the International Cybernetics Newsletter, as part of its ‘founding fathers of cybernetics’ series (Scott, 1979). I offer it here as a contribution to this special issue of C&HK because (i) I believe my younger self did quite a good job of overviewing von Foerster’s career (recall, he ‘retired’ in 1976) and (ii) the article...
