Sigma Sigma Delta
On November 11, 1924, Lanterna Laetitiae was organized at Bucknell University. Four years later, the decision to become a national organization prompted the name change to Sigma Sigma Delta. The sorority had "open membership as a fundamental principle" (Bucknell University website).
Four more chapters were chartered: Susquehanna, Northwestern, Baldwin-Wallace, Ohio Marietta (Baird's).
Northwestern's came from the local Aeukiga and Baldwin-Wallace's from the Calumet Club (Baird's).
In Ohio Marietta's catalogue (1933), the sorority is listed as "Sigma Sigma Delta National Open Sorority" (p. 23)
By 1938, all chapters had dissolved. Northwestern's went to Phi Omega Pi. Baldwin-Wallace's reorganized as Theta Tau Delta, then affiliated with Phi Mu.
The sorority's official colors were green and white; the flower was the white carnation; the publication was The Evergreen (L'Agenda).
