I received word from a friend of mine who used to work for the Armory Foundation that Dr Sander passed away unexpectedly. I not sure when or what happened. Dr Sander was the key person behind the revitalization of the Fort Washington Armory in New York from a homeless shelter to the indoor track & field hub it is today (2013 article about this work is available here - http://www.runblogrun.com/2013/12/track-field-visionary-dr-norbert-sander-armory-savior-by-david-hunter.html).
