Although not a brother fraternity, Delta Zeta has a unique bond with Phi Delta Theta in that one of the brothers, Dr. Guy Potter Benton, is our sorority's Grand Patron. Dr. Benton made the decision, when he was President of Miami University of Ohio, to allow women to matriculate and he provided much guidance, inspiration and advice to our six founders.
He even helped keep our Ritual a secret when a Beta brother stole a copy out of the hands of our secretary and Dr. Benton (if I recall from my pledge handbook) pursued the villain and won back the document "not by his sprinting ability but by virtue of his official position"
