Dr. E. Lee SpenceDr. E. Lee Spence - Owner

Dr. E. Lee Spence
Vice President
Internationally Known Shipwreck Expert

Dr. E. Lee Spence is an internationally known expert on shipwrecks and sunken treasures. Spence found his first shipwrecks in 1960. The late Peter Throckmorton (who is frequently described as the "father of marine archaeology") once compared Spence to Heinrich Schlieman. Schlieman is considered the founder of historic archaeology. Spence graduated Cum Laude from the University of South Carolina in 1976, where he obtained a Bachelor of Arts Degree in Interdisciplinary Studies with an academic concentration in marine archaeology.

Spence's past work has been funded by such institutions as the Savannah Ships of the Sea Museum, the College of Charleston, the South Carolina Committee for the Humanities and the National Endowment for the Humanities. In 1991 and '92, Spence served as Chief of Underwater Archaeology for Providencia, a 40,000 square-mile archipelago in the Western Caribbean. He has worked on the wrecks of Spanish galleons, pirate ships, Great Lakes freighters, modern luxury liners, Civil War blockade-runners and submarines. He has authored more than two dozen books, and has served as editor for a number of nationally distributed magazines.

Spence was the discoverer of the Civil War submarine Hunley, and in 1995, at the official request of the State of South Carolina Hunley Commission, he donated all of his rights to the wreck to the State. The Hunley has been described as the most important underwater archaeological discovery of the 20th century.

Although he has discovered numerous historically significant shipwrecks, including the Confederate cruiser Georgiana, and has salvaged millions of valuable artifacts, Spence considers his identification of George Trenholm, who was the owner of the Georgiana, as the "Real Rhett Butler" to have been his most important literary discovery.

Spence is also an award-winning cartographer and has published a number of maps and charts dealing with shipwrecks and treasure.
