The company that owns the salvage rights to the wreck of the Titanic is holding a virtual memorial for one of the world's foremost experts about the ship a month after he died with four others in a submersible explosion.
Paul-Henri Nargeolet, 77, died when the Titan submersible descended into deep North Atlantic waters on June 18 to explore the Titanic — something Nargeolet had done dozens of times before. Investigators believe the submersible, owned by a private company, imploded during the descent, killing everyone aboard.
