It took University of Maine professor Warren Riess some 30 years to solve the mystery of a ship.
It was buried for hundreds of years below filled-land in lower Manhattan, and was discovered in 1982 as preparations were underway to build a 30-story building on the site. Archaeologists who first spotted it knew they needed expert help, so they called Riess, who had just received a master's degree in nautical archaeology.
Warren Riess and his partner, Sheli Smith, wrote "The Ship that Held Up Wall Street."
