Alpha Omicron Pi (
ΑΟΠ,
AOII) is an international
women's fraternity promoting friendship for a lifetime, inspiring academic excellence and lifelong learning, and developing leadership skills through service to the fraternity and community. ΑΟΠ was founded on January 2, 1897 at
Barnard College on the campus of
Columbia University in New York. Its founders were Stella George Stern Perry, Helen St. Clair Mullan, Elizabeth Heywood Wyman, and
Jessie Wallace Hughan. The four founders met in the Columbia Law Library to begin their fraternity and to forever seal their friendships and the friendships of all future members. The philosophy which the founders guided their principles included membership to women who share their belief in lifelong friendship, service and love. Membership is offered to women regardless of ethnicity, religion or socio-economic background.
