In Becoming Belle da Costa Greene: A Visionary Librarian through Her Letters, Deborah Parker chronicles the making and empowerment of a female connoisseur, curator, and library director in a world where such positions were held by men. Belle da Costa Greene (1879-1950) was Pierpont Morgan's personal librarian (1908-1913) and the first Director of the Morgan Library (1924-1948). She was also the daughter of two mixed-race parents and passed for white. In the nearly six hundred letters that Greene sent to art historian Bernard Berenson (1865-1959), Parker identifies Greene's energetic pursuit of exceptional opportunities, illuminating the artistry and imaginative features of Greene's writing-her self-invention, her vibrant responses to books and art, and her pathbreaking work as a librarian. As Greene transformed a private library into a magnificent public institution, she also transformed herself: hers was a life both lived and writ large.
