[SIGCIS-Members] Seymour Papert has died

See http://news.mit.edu/2016/seymour-papert-pioneer-of-constructionist-learning-... Papert was one of the co-inventors of the Logo programming language. My memory is that his group of Logo people was located at 545 Technology Square in Cambridge, MA, among the Project MAC (later LCS) groups of MIT computing research people.
