The National Memorial African Bookstore office of Mr. Lewis Michaux.
Mr. Michaux began the bookstore in Harlem in 1939, with only five books, a storefront, and $100—along with a great deal of passion and determination. He opened the bookstore to sell books by and about black people.
The National Memorial African Bookstore became an intellectual, cultural, and social hub of the community before, during, and after the Civil Rights era, and was frequented by such luminaries as Malcolm X and Langston Hughes before its doors closed in 1975. [source]
