Here's what the Alpha Xi Delta history says about Alpha Sigma chapter

First founded as the local Xi Delta in December 1922, the group changed its name to Gamma Nu in 1924 and petitioned Alpha Xi Delta for a charter a year later. Gamma Nu was installed as Alpha Xi Delta's 42nd chapter on June 5, 1926. While Alpha Sigma produced many campus leaders, it was unable to survive the college population decline during World War II and became dormant in 1943.

The chapter was re-established in 1968 and enjoyed an active, productive 5 years before the unrest of the early '70s and the unfavorable housing situation in the community once again neccessitated closure in 1973.
