A treasure trove of artifacts was uncovered at the Lutheran Theological Seminary at Gettysburg when workers broke through the walls and ceilings during the renovation of a 180-year-old dormitory. Found were a nearly century-old wardrobe signed by decades of students, letters to Civil War soldiers, a plaster relief of Martin Luther and four men's shoes, the oldest dating to 1830. The shoes were deliberately damaged before being stored in the walls, apparently a folk custom intended to bring good luck. In one of the letters, a father encouraged his soldier son to kill "Old Jeff," meaning Jefferson Davis, president of the Confederacy. Known as the Old Dorm, the building was converted into a hospital during the Civil War. It is being turned into an interpretive museum showing neglected dimensions of the Civil War (Evening Sun, March 12).
