A statue of a Naperville firefighter in rescue mode rushing into danger illuminates the night sky along Jefferson Street in a tiny park nestled near the bridge over the west branch of the DuPage River. “Ladder of Light” created by Naperville artist Paul Kuhn in partnership with Dark Moon Designs and Intelligent Lighting Creations was unveiled Monday just after dusk on the 50th anniversary of the day three Naperville firefighters were killed when their fire truck was struck by another vehicle. About 200 people were on hand in the park and in the parkway across the street for the hour-long ceremony at Fireman’s Memorial Park, which unintentionally included the lights and sirens of an ambulance and fire truck headed east on Jefferson Street in response to an emergency call. What makes this piece different from other sculptures in Naperville are the two large beams of light projected from the base that at night make it appear that the firefighter is climbing a ladder.
