Without Dr. Robert Ballard, the location of the wreck might have taken awhile longer to discover.
But is is film director James Cameron who reignited the imagination about the fateful voyage with his blockbuster 1997 film The Titanic.
Cameron's film was not the first, and countless books, articles, papers and documentaries have been produced over the years.
Dr. Ballard has continued his research into the exploring the sea bottom and discovering wrecks. Cameron's continued fascination with the wreck has led to dives to uncover how exactly she sank.
