Two retired teachers from Schuylkill County Ned Eisenhuth and Fred Lutkus presented the program. They worked with students at Hamburg Area School District as a senior graduation project in the metal shop to create a replica of the lantern, the heart of the mystery of the H.L. Hunley a submarine that disappeared shortly after becoming the first sub in history to sink an enemy warship on February 17, 1864. The H.L. Hunley went undiscovered on the bottom of the Atlantic Ocean off the South Carolina coast until being found in 1995. It was raised in 2000. They created four replicas of the lantern and one is showcased at the Warren Lasch conservation Center in Charleston, S.C., one is in the Civil War Museum in Harrisburg, and two others are in storage. Christine Roth was the program chairperson.
