The latest in a series of historical markers that honor Bulloch County’s past was dedicated Monday on the campus of Georgia Southern University. Members of the Bulloch County Historical Society and University President Brooks Keel gathered at Sweetheart Circle, near the college’s main entrance, to christen the group’s eighth marker, this time honoring a tiny agricultural and mechanical school that grew into the state’s third-largest university. A new plaque situated among the oaks near the Marvin Pittman Administration Building pays tribute to the First District A&M School, which in 1908 opened its doors with just 42 students, but developed into the nationally recognized doctoral/research institution Georgia Southern University.
