The Pi Iota chapter, oldest of the Worcester Polytechnic Institute fraternities, founded its local chapter in the fall of 1891. The star of Phi Gamma Delta was brought to the Worcester Tech campus largely through the efforts of Brother Archibald MacCullagh, a member of the Beta chapter at the University of Pennsylvania. Brother MacCullagh had transferred to Tech, and together with several of his buddies decided to band together in a club. As fraternities were just coming into popularity, a petition was submitted to Phi Gamma Delta, and the society was admitted on November 20, 1891. The chapter's original cabinet consisted of Hugh M. Southgate (Senior Class President), Fred A. Morse, and Albert E. Culley.

Many years later, in recognition of Brother Morse's contributions to the chapter, the Alumni Corporation chose to be known as the F.A. Morse Association. The call letters Pi Iota were selected because of the chapter's location at Worcester Polytechnic Institute, and reflect Phi Gamma Delta's loyalty to the institution that fostered it. After several experiments in location, Brother Robert S. Parks one of the chapter's original members purchased a parcel of land on the corner of Boynton and Salisbury Streets, from Mr. Stephen Salisbury. Brother Parks donated the land to the chapter and the present house was constructed as one of the first houses built in the United States strictly for fraternity use on May 1, 1899.

Due to the fact that it was the first fraternity at Tech, the college cooperated greatly with the organization, and the opening of the chapter house was a huge event on the hill. Over the course of its one hundred and fourteen years at WPI, Phi Gamma Delta has given many young men the opportunity, to learn and excel academically, socially, and fraternally.

Phi Gamma Delta is a leading fraternity at WPI and our current numbers show it. We are welcoming 20 new members into our brotherhood this year, and welcome all past brothers to become more involved through our alumni website.
