Founded in 1937 and formally opened three years later, the Philadelphia Pyramid Club was a small, exclusive club for black professionals. Its mission was to foster the “cultural, civic, and social advancement of Negroes in Philadelphia.” The membership fee was $120, and monthly dues were $2.40.

The club hosted a wide range of social and cultural activities, including performances by Marian Anderson and Duke Ellington and, after 1941, annual art exhibitions for African American artists. It also hosted events with Dr. Martin Luther King Jr. and physicist J. Robert Oppenheimer, father of the atomic bomb. During the Pyramid Club’s heyday, its membership rolls were a Who’s Who of black Philadelphia.

The club was dissolved in 1963.
