Passing of Ernst von Glasersfeld

This evening I came home to news about Ernst's death this morning, 12 November 2010, at 7am US east coast time.  Ernst was seen by some as the originator of 'radical constructivism'.  I was fortunate to see him again at the recent ASC Conference in Troy, upstate New York where he gave, as always, an erudite talk as the conference after dinner speaker.  He was clearly pleased to be amongst that community even though his deafness made connection difficult.  Reports of his death at the age of 93 are beginning to appear.
