Theta Sigma Tau was a non-national co-ed fraternity on the campus of Ripon College in Ripon, Wisconsin. Founded May 2, 1910, it was the oldest Greek organization on campus until it closed in 2021. Tau, as it is affectionately referred to by its members, has been known at various times as the Elms Club, Sanford House, and the now inactive Zeta Tau chapter of the national fraternity Sigma Nu. One past member of renown is the actor Harrison Ford.
In 1980 Theta Sigma Tau became a coed "fraternity," the members believing that the richest living group experiences come when men and women can live together as equals. A small fraternity with a long and distinguished history, its members were dedicated to academic excellence and social consciousness.
