Alpha Chi Omega and Zeta Tau Alpha share a Founders' Day, October 15.
Alpha Chi Omega's seven founders, Anna Allen, Olive Burnett, Bertha Deniston, Amy DuBois, Nellie Gamble, Bessie Grooms and Estelle Leonard, were students in the DePauw School of Music. With the guidance and support of James Hamilton Howe, Dean of the School of Music, they created an organization that at its beginning insisted that its members possess some musical culture. The group was organized on October 15, 1885.
