Indiana University of Pennsylvania (also known as IUP) was founded in 1875 as a state teacher's college. There are three buildings on campus which were named after Phi Sigma Pi Brothers: Foster, Walsh, and Wilson, and also Beard Auditorium in Stouffer Hall.
Eta Chapter was closed in 1942 because of World War II, but in February of 1946, many Brothers returned to IUP and reactivated the chapter. Past president Ellwood Sheeder led the reactivation efforts, aided by Charles Tyger, John Feather, and Charles Stewart. On May 22, 1951, Eta's president, Joe Caletvi, decided to close the chapter because he felt it was not living up to the National Constitution.
