Greene formed deep bonds with her female colleagues. Marguerite Duprez Lahey, a bookbinder, was a confidant to Greene, who in this letter shared her daydreams of running away to Europe. Ada Thurston, Greene’s assistant and first hire after becoming librarian, would remain a close friend even after leaving the Morgan. Written following the death of J. P. Morgan Jr., the letter to Thurston, affectionately called “Thursty,” shows a profound connection between the two women as well as the personal importance of the Morgan Library in their lives.
