David Larsen (1960-2011) was a National Park Service Interpretive Ranger who became the Manager of Interpretive Training with National Park Service (NPS) at The Mather Employee Development Center. After many years as a frontline interpreter at sites such as the the Vietnam Memorial and Harper's Ferry National Historic Park, David stepped up to become a leader in Interpretive thought, philosophy, and training.   Bill Gwaltney, Connie Rudd, and Kim Sikoryak were colleagues and collaborators with David during his training years and knew him well. Tim Merriman interviews the trio on “Reflections on Interpretation” about the enduring impact David's philosophy on training and the conceptual framework of Interpretation that has impacted the entire profession of heritage interpretation. Thanks is due NPS for our use of short clips of David speaking via a series of 5-videos available on youtube.com. We highly recommend you watch the entire series of about one hour and fifteen minutes. David's excellent interactive book entitled “Meaningful Interpretation” published by the Eastern National Cooperating Association is available through the association.
