Belle da Costa Greene has a secret that she must protect at all cost. She was not born Belle da Costa Greene, but Belle Marion Greener, the daughter of Richard Greener, the first black graduate of Harvard and a well known advocate for equality. In her twenties, Belle was hired by J.P. Morgan to curate a collection of rare manuscripts, books, and artwork for the Pierpont Morgan Library. Belle soon became a fixture in New York City society and one of the most powerful people in the art and book world. She became known for her impeccable taste and negotiating skills. Belle, a powerful woman, faced the challenge daily of hiding her true identity to be able to work where she does. She had to go lengths to protect herself, her family, and her legacy. She had to preserve her carefully crafted white identity in the racist world in which she lives.
