At the end of the month, the University of Virginia will say goodbye to one of its longest-tenured and most beloved employees. Alexander “Sandy” Gilliam, the university’s historian, is one of a few people who can truly say he has lifelong ties to UVa. The men in his family have been attending UVa since the 19th century. As a child, he remembers visiting the old natural history museum in Brooks Hall. He graduated in 1955 and came back to work at the university in 1975. He hasn’t left since.
