The Gamma Phi Society is the genesis organization that led to the founding of the Delphic Fraternity. Gamma Phi was formed sometime before 1833 (the actual founding date is unknown) at the Hamilton Literary & Theological Institution, one of the former names of today's Colgate University in Hamilton, New York. Gamma Phi was the first college literary society formed at Colgate.
Not much is known about Gamma Phi, except that at least half of the student population were members. The society is credited as the catalyst for fraternity and sorority life at Colgate University. Gamma Phi was later incorporated into the Adelphian Society.
