Happy Founders’ Day to Zeta Phi Beta Sorority Incorporated!  The community-conscious, action-oriented organization was founded this day in 1920 by five collegiate women on the campus of Howard University in Washington, DC.  It is one of nine historically African American Greek Lettered Organizations.  Opera singer Madame Lillian Evanti was a member of the sorority and in this undated image by Paul Henderson in the  Evans-Tibbs collection, she proudly performs for her Sisters.
