I had the privilege of getting to know John Wheeler late in his career. He was a wonderful man with a wonderful joker's sense of humor, in addition to having a wonderful sort of OCD for an academic (a significant portion of the library in the Physics department at Princeton was dedicated to holding a copy of every book and article and proceeding referenced anywhere in the mighty book that is Misner Thorne and Wheeler, all carefully filed and categorized and organized by John Wheeler).
