Renowned undersea explorer and Titanic discoverer Robert Ballard delivered the keynote address for Illinois State University’s Science and Technology Week on April 17. His address, “Exploring the Living Dream,” included a question and answer session with audience members.

Ballard, best known for his 1985 discovery of the wreck of the Titanic, has had an extensive career of underwater explorations using manned and unmanned submersible vehicles. His work has helped scientists to better understand life in the deep oceans and the internal composition of the earth’s crust. Because of his work, historians and the general public now have a better understanding of famous shipwrecks such as the German battleship Bismarck, the liner Lusitania and two ancient Phoenician ships in the Mediterranean Sea, the oldest shipwrecks ever found in deep water.
