@ The Charles L. Blockson Afro-American Collection, Sullivan Hall, 1310 Polett Walk What do Lena Horne, Aretha Franklin, Camille Cosby and Winnie Mandela have in common? All of these talented, important women were Delta Sigma Thetas. The Blockson Collection’s fall exhibition celebrates the Epsilon Delta Chapter of Philadelphia, started at Temple fifty years ago. Hundreds of women–some are household names and some you do not yet know–have been part of this important organization of African American women. Look at their history, and take a trip into Philadelphia’s past, with this exhibition.
