Obviously, Washington Roebling was an extremely energetic and intellectually charged individual. For diversion, he directed these energies into his lifelong hobby and passion, his rock and mineral collection. That priceless 16,000-piece collection was eventually donated by his son, John A. Roebling II, to the Smithsonian Institution. It has since become the cornerstone of the Museum of Natural History's mineral and gem collection.
