Calderon, who retired from NIU in 2008, was a fixture at Northern Illinois home and away football games for many, many seasons. In addition to operating the public address and music systems during games, he was responsible for the coaches' headset communications both home and away. At head coach Joe Novak's request, Calderon would set up "music" (often the opposing teams' fight songs, crowd noise and band played on a loop) to be blared at footbal practice during the week to simulate the other team's stadium atmosphere. On road trips, he would spend time illustrating post cards which he would then send to his many friends.
Calderon graduated from Northern Illinois in 1982 and was active in designing, installing and maintaining audio/visual systems around campus in addition to working with the football team. Read much more on Calderon, here. A memorial service was held Wednesday, May 8, in DeKalb.
