From Aurora Magazine of Sigma Gamma Rho and Other Sources: Sunday, November 12, 1922: Seven young African American women educators met on the Irvington campus of Butler College to found Sigma Gamma Rho Sorority. The Grand Chapter of Sigma Gamma Rho was incorporated the following month under the laws of Indiana. The founding members of Alpha Chapter were Butler College graduate Nannie Mae Gahn; Indianapolis Normal School and Butler College graduate Vivian Irene White; Indianapolis Normal School graduates Mary Lou Allison, Bessie Mae Downey, Dorothy N. Hanley, and Cubena McClure; and Indiana State Teachers College graduate Hattie Mae Annette Dulin. Founded on the tenets of excellence in scholarship, sisterhood, and service, Sigma Gamma Rho was initially composed of young women who had had normal training and who were working for college degrees. The sorority continues to adhere to its slogan Better Service, Greater Progress.
