Gamma Delta Sigma Chapter of Sigma Gamma Rho Sorority, Inc. was chartered as a result of the envisioned dream of Allene V. Jones Taylor. Her aspiring dream, to work in the Greater Miami community and mold the character of youth, captured the minds and hearts of ten very special, dedicated, and intelligent women. They concurred in the idealistic vision of establishing a chapter.

Soror Beatrice Keys, then Basileus of Beta Iota Sigma Chapter, Daytona Beach, Florida; Soror Bertha Rhoda Black, Anti-Grand Syntaktes, St. Louis, Missouri; and Southeastern Regional Syntaktes Soror Myrtle S. Russell organized the first Aurora Club on February 5, 1955. The zeal with which Soror Taylor and the women worked was highly commended by Soror Elizabeth Espy Curtis and Soror Ruby Thomas Rayford, graduate members of Sigma Gamma Rho Sorority, Inc. The two graduate sorors advised and nurtured this dream with deep sisterly support. When the group was prepared, Soror Curtis, Soror Rayford, and Soror Russell conducted the pledging ceremonies at the home of charter member, Allene V. Taylor.

On March 11, 1955, a charter was granted to Gamma Delta Sigma at the Southeastern Regional Conference, in Tampa, Florida. It was in Tampa under Beta Kappa Sigma Chapter that the "burning sands" of Greekdom was crossed. The charter members and first sorors included Vera Austin, Mable D. Barlow, Naomi Gooding, Inez K. Davis, Naomi Espy, Mallie Hunter, Allene V. J. Taylor, Jane D. Lewis, Eunice W. Liberty, Walton Y. Robinson, Roberta Thompson, and Velma Hurd (an Aurora from Colorado State University).  Soror Curtis and Soror Rayford transferred immediately into the chapter. Soror Thomas was the first Basileus of Gamma Delta Sigma.
