Terry Huizing is a lifelong mineral collector who has indulged his interest in calcite by collecting on every continent except Antarctica, but typically much closer to home in the mines and quarries of the American Midwest. His childhood interests in minerals led him to pursue electives in mineralogy while completing a degree in chemical engineering from the University of Michigan. Gainful employment followed in Cincinnati, Ohio, where he interacted with the mineral community accepting volunteer responsibilities such as show manager (GeoFair), mineral curator (Cincinnati Museum Center), and consulting editor (Rocks & Minerals). Terry is a seasoned exhibitor, a published author, and an occasional speaker.
