Sigma Gamma Rho Sorority, Inc. was organized on November 12, 1922, in Indianapolis, Indiana, by seven young educators: Mary Lou Allison Gardner Little, Dorothy Hanley Whiteside, Vivian White Marbury, Nannie Mae Gahn Johnson, Hattie Mae Annette Dulin Redford, Bessie Mae Downey Rhoades Martin and Cubena McClure. The group became an incorporated national collegiate sorority on December 30, 1929, when a charter was granted to Alpha chapter at Butler University.

Today there are over 85,000 members and over 500 chapters in the U.S., Bahamas, Bermuda, the U.S. Virgin Islands, Canada, Germany, and Korea.
