The Founding of Theta Xi
Theta Xi was founded at Rensselaer Polytechnic Institute (RPI) in Troy, New York, on April 29th, 1864, by Peter Henry Fox, Ralph Gooding Packard, Christopher Champlin Waite, George Bradford Brainerd, and Nathaniel Henry Starbuck. Minutes if the original meeting, Constitution and Ritual have been preserved by the Fraternity to this day. Our tradition is truly continuous.
The only college Fraternity founded during the civil war, Theta Xi’s roots can be traced to the RPI secret society, Sigma Delta. Sigma Delta, although a popular campus organization, suffered from internal conflict. This became evident with the resignation of one of its most prominent members, George Brainerd. In an effort to heal the problem, the members decided to have a blackball vote on all members. The voting led to the removal of all but eight members. Instead of continuing as Sigma Delta, these eight members chose to establish a completely new Fraternity: Theta Xi.
