College of Charleston, Charleston, South Carolina, April 21, 1979
Zeta Sigma chapter was installed as the fifth sorority at the College of Charleston in 1979. The oldest municipal college in the United States, the College of Charleston was established in 1785. It became a municipal college in 1837, admitted females in 1918 and became a state-sponsored institution in 1970. Helen Anderson Pruitt, Beta Epsilon - South Carolina, was instrumental in colonizing the chapter as was Mary Bel Higgins Howe, also of Beta Epsilon, who opened her home, the Calhoun Mansion, to rush parties for years. The historic chapter house was built in 1849 and is complete, it is told, with a secret room and staircase. The university owns the house, but Beta Zeta owns the furnishings. The chapter has always been devoted to philanthropy, winning numerous awards, but also emphasizing scholastics and campus involvement. They had the highest GPA on campus for seven consecutive years and have won Greek Week many times. Several alumnae have been instrumental in Zeta Sigma's success, including Karen Moon Keels, Beta Epsilon, and Sally Blackburn Dozier and her daughter Leigh Dozier Taylor, both of Kappa - Samford. Former Foundation President, Chloe Knight Tonney has served in many ways. The chapter won Golden Lion in 2007.
