Greenspan's series "16 Days of Glory" from the 1984 Los Angeles Olympics solidified my interest in the Olympic Movement during my early teens, and it was an honor to meet Greenspan more than once, starting in 1997 at the premiere of his documentary film for the Centennial Olympic Games of Atlanta.
I was also lucky to be in the room when the International Society of Olympic Historians (ISOH) presented Greenspan with an award on the eve of the Vancouver 2010 Olympic opening ceremony. Greenspan's health was clearly deteriorating but he was in good spirits.
The Olympic Family lost a major contributor. Fortunately, Greenspan's work will remain accessible for future generations.
