Delta Nu was formally pledged on May 15, 1959, the 108th anniversary of the sorority. Installation followed the next day for 45 collegians and five alumnae members of the Hesperian Society - a literary society founded in 1914. Delta Nu originally met in a room in the Memorial Hall Student Center before moving into chapter facilities in a residence hall. The hall is located in an area exclusive to Greeks, giving it a community-like atmosphere. When the university introduced plans to renovate Greek housing, Delta Nu successfully challenged the decision, remaining in their residence hall and preserving years of memories and traditions. Bettie McHaney Talbert, Alpha Gamma - Missouri, was instrumental in bringing Alpha Delta Pi to campus and served for many years as an advisor and international officer. Lisa Richardson Quick was a long-serving international officer. The chapter has received the Golden Lion Award three times.
