Alpha Omicron Pi was founded on January 2, 1897 at the home of Helen St. Clair (Mullan). She and three of her Barnard College friends, Stella George Stern (Perry), Jessie Wallace Hughan, and Elizabeth Heywood Wyman had pledged themselves to the organization on December 23, 1896. That first pledging ceremony took place in a small rarely used upstairs room in the old Columbia College Library.
Celebrating a Founders' Day on the second day of the new year proved to be a challenge for the organization, so Alpha Omicron Pi now celebrates Founders' Day on December 8, Stella's birthday.
