Sigma Pi (ΣΠ) is a collegiate fraternity with 233 chapters at American universities. As of 2021, the fraternity had more than 5,000 undergraduate members and over 110,000 alumni. Sigma Pi headquarters are in Nashville, Tennessee. The fraternity was founded on February 26, 1897, by William R Kennedy, James T Kingsbury, George M Patterson, and Rolin R James at Vincennes University. The group was initially known by the Greek letters Tau Phi Delta (ΤΦΔ), but was renamed Sigma Pi in 1907. The change of name was instigated by Robert George Patterson, then a student at Ohio State University. Patterson had wanted to join the Sigma Pi literary society at Illinois College in Jacksonville, Illinois, but the latter group had rejected his request to expand to OSU. In 1907 Patterson approached Tau Phi Delta members, claiming to represent a historic fraternity called Sigma Pi that dated to the 18th century. Tau Phi Delta accepted Patterson's invitation to merge and adopted the named Sigma Pi. More information...
