The first ceremony held was on November 17, 1946, in the lobby of Jackson Davis Hall on the campus of Florida Agricultural and Mechanical College. The ceremony which was attended by Southern Regional Director, Addie D. Jones, welcomed the new graduated chapter into ranks of Delta Sigma Theta.
The first initiated welcome into the chapter were: Barbara Baker Boardley, Amerique C Briggs, Willie Mae Miles, Willie B. Stewart and Genevieve J. Wheeler (Thomas) which was held in the home of Glovenia Baker. In November 1958, Gamma Eta Sigma Chapter was renamed the Tallahassee Alumnae Chapter as amended by the Constitution and Bylaws of the Grand Chapter at the 25th National Convention held in Washington, D. C., August 1958. The term “graduate” chapter became obsolete and “alumnae” was adopted.
