Kappa Kappa Gamma (ΚΚΓ) was founded at Monmouth College in Monmouth, Illinois.
The idea of Kappa Kappa Gamma is said to have been conceived in a conversation between two college women, Mary Louise Bennett and Hannah Jeannette Boyd, on a wooden bridge over a stream on the Monmouth College campus in the late 1860s. Although the groundwork of the organization was developed as early as 1869, the 1876 Convention voted on October 13, 1870 as Founders Day, because no earlier charter date could be determined. This makes Kappa Kappa Gamma one of the oldest women's Greek-letter societies in existence today. It is technically a "women's fraternity" rather than a sorority, because the organization came into existence before the term "sorority" had been coined.
The fraternity was formed by six pioneering women with a love of learning, pictured above. They are responsible for Kappa's name, secret motto, constitution, and badge.
