Delta Kappa Epsilon has as long a history as any fraternity, and its brothers have held many important leadership positions.
An Eta (Virginia) alumnus recently found a pin from a brother from the 1860's. The pin was engraved with "Minor" on its back. In their search to find out just who this brother was, they dug up a couple candidates. The winning candidate was a fellow by the name of Charles Nelson Berkeley Minor, who has his share of stories; he was at the Appomattox Courthouse for the surrender.
Berkeley's brother, Charles Landon Carter Minor, made more of a difference for our lives. Carter was the first president of Virginia Agricultural and Mechanical College, then a new land grant university and now Virginia Tech. I recommend following the link above to read about his history with the school.
