RMS Titanic Founder G. Michael Harris put the first Salvage Operation of the RMS Titanic in October 1986. The first Titanic expedition began in July 1987 and was financed by Titanic Ventures Limited Partnership, George Tulloch, Connecticut, and Oceanic Research & Exploration, G. Michael Harris, Florida. These co-partners led a $6 million expedition to the ship, and recovered artifacts beneath the surface of the North Atlantic. In order to recover these artifacts, George Tulloch, G. Michael Harris and their team completed 32 dives to Titanic in the “Nautile”, a deep-diving submersible chartered by Oceanic Research and Exploration in a partnership with Ifremer, the French Research Institute for Exploration of the Sea. This is the greatest number of deep-sea dives ever completed for any televised project. The company had an OTC ticker symbol of SOST. In 1994 it won a Virginia court order to get salvor-in-possession rights to the ship.
