In 1932, after rusting in a public park for more than two decades, the U.S.S. Holland was cut up for scrap, a sad and ignoble end for the vessel hailed as the first modern submarine. Beyond sentiment, however, the Holland’s unseemly demise was a historical tragedy. With the ship destroyed and most of the plans used to build it scattered and lost, researchers long believed that the opportunity to study the innovative genius of the submarine and its inventor, John P. Holland, had disappeared forever. Seventy years later, however, thanks to the patient historical spadework of a devoted amateur historian and the magic of 3D digital design tools from IBM and Dassault Systemes, the Holland has come back to life in virtual reality.
